Racial,Ethnic, and Sex Disparities in Patients With STEMI and Cardiogenic Shock

ObjectivesThe aim of this study was to evaluate the combined impact of race, ethnicity, and sex on in-hospital outcomes using data from the National Inpatient Sample.BackgroundCardiogenic shock (CS) is a major cause of mortality following ST-segment elevation myocardial infarction (STEMI). Early revascularization reduces mortality in such patients. Mechanical circulatory support (MCS) devices are increasingly used to hemodynamically support patients during revascularization. Little is known about racial, ethnic, and sex disparities in patients with STEMI and CS.MethodsThe National Inpatient Sample was queried from January 2006 to September 2015 for hospitalizations with STEMI and CS. The associations between sex, race, ethnicity, and outcomes were examined using complex-samples multivariate logistic or generalized linear model regressions.ResultsOf 159,339 patients with STEMI and CS, 57,839 (36.3%) were women. In-hospital mortality was higher for all women (range 40% to 45.4%) compared with men (range 30.4% to 34.7%). Women (adjusted odds ratio [aOR]: 1.11; 95% confidence interval [CI]: 1.06 to 1.16; p < 0.001) as well as Black (aOR: 1.18; 95% CI: 1.04 to 1.34; p = 0.011) and Hispanic (aOR: 1.19; 95% CI: 1.06 to 1.33; p = 0.003) men had higher odds of in-hospital mortality compared with White men, with Hispanic women having the highest odds of in-hospital mortality (aOR: 1.46; 95% CI: 1.26 to 1.70; p < 0.001). Women were older (age: 69.8 years vs. 63.2 years), had more comorbidities, and underwent fewer invasive cardiac procedures, including revascularization, right heart catheterization, and MCS.ConclusionsThere are significant racial, ethnic, and sex differences in procedural utilization and clinical outcomes in patients with STEMI and CS. Women are less likely to undergo invasive cardiac procedures, including revascularization and MCS. Women as well as Black and Hispanic patients have a higher likelihood of death compared with White men.     

The correlations among racial/ethnic groups,hypertriglyceridemia, thrombosis,and mortality in hospitalized patients with COVID-19

Reports of racial and ethnic disparities regarding both rates of infection of the SARS-CoV-2 virus and morbidity of the coronavirus disease-19 (COVID-19) contain profound differences depending on the population. Our previous study has shown that patients with COVID-19 who developed hypertriglyceridemia during hospitalization have a 2.3 times higher mortality rate. However, whether the correlation between hypertriglyceridemia and mortality has disparity among different racial and ethnic groups is unknown.In this study, we investigated the impact of race/ethnicity on the correlation between hypertriglyceridemia and mortality in hospitalized patients with COVID-19. De-identified information from 904 hospitalized patients diagnosed with COVID-19 between March 2020 and June 2021 were extracted from the Medical College of Wisconsin Clinical Data Warehouse. A multivariable regression analysis suggested that the Asians and non-White Hispanics had 4 or 3.9 times higher mortality rate, respectively, after adjusting for age, morbid obesity (BMI ≥40), and gender. The hypertriglyceridemia (≥150 mg/dL) was associated with higher mortality, after adjusting for age, gender, and morbid obesity. The baseline hypertriglyceridemia occurrence had relevantly more consistent percentages among all racial/ethnic groups. However, non-White Hispanic and Asian patients had the highest frequencies of peak hypertriglyceridemia occurrence during hospitalization. The peak hypertriglyceridemia developed during hospitalization correlates with the incidence of thrombosis after adjusting for morbid obesity, age, and sex. In summary, in this retrospective study of 904 hospitalized COVID-19 patients, Asians and non-White Hispanics had a greater likelihood of developing hypertriglyceridemia during hospitalization and mortality than White patients.     

Good post-transplant outcomes using liver donors after circulatory death when applying strict selection criteria: A propensity-score matched-cohort study

Introduction and ObjectivesOutcomes of liver transplantation (LT) with donors after circulatory death (DCD) have been considered suboptimal due to higher rates of ischemic cholangiopathy, especially when the super-rapid recovery (SRR) technique is used. This study aimed to compare the incidence of complications between recipients receiving DCD vs those receiving donors after brain death (DBD) in a large-volume liver transplant centre.MethodsWe performed a retrospective cohort study (LT from January 2015 to December 2018) comparing recipients who underwent a LT with DCD vs. a control group of LT with DBD, matched 1:1 without replacement by propensity score matching that included the following variables: LT indication, recipient sex and age, donor age and MELD score.Results51 recipients with DCD-LT (29 SRR, 22 normothermic regional perfusion [NRP]) were matched with 51 DBD-LT recipients. Biliary complications were more frequent in DCD, 10% (n=5), all with SRR technique, vs 2% (n=1) in the DBD group, p=0.2. Two patients (4%) suffered primary graft non-function in the DCD group (1 SRR and 1 NRP) versus zero in the DBD group (p=0.49). Postoperative bleeding and reinterventions were also higher in the DCD group: 7 (13.7%) vs 1 (1.95%) and 8 (15.7%) vs 2 (3.9%) respectively (p=0.06 and 0.09). On the 1^st postoperative day AST/ALT peak was higher in DCD (p≤0001). The incidence of rejection, vascular complications, renal injury, hospital stay, and readmissions were similar in both groups. Cumulative 1-, 2-, 3- and 4-year graft and patient survival were also similar.ConclusionsDCD donors are an adequate option to increase the donor pool in LT, achieving similar graft and patient survival rates to those achieved with DBD donors, especially when the NRP technique is used.     

The effectiveness of a structured group education programme for people with established type 2 diabetes in a multi-ethnic population in primary care: A cluster randomised trial

Background and aimsStructured self-management education has been shown to be effective in type 2 diabetes (T2DM) but more research is needed to look at culturally appropriate programmes in ethnic minority groups, where prevalence of T2DM is higher and diagnosis earlier. The study tested the effectiveness of a group education programme for people with established T2DM in a multi-ethnic primary care population.Methods and resultsCluster randomised trial conducted in two multi-ethnic UK sites. Practices were randomised (1:1) to a structured T2DM group education programme or to continue with routine care. A culturally-adapted version was offered to South Asians, who formed the majority of ethnic minority participants. Other ethnic minority groups were invited to attend the standard programme. Primary outcome was change in HbA1c at 12 months. All analyses accounted for clustering and baseline value.367 participants (64(SD 10.8) years, 36% women, 34% from minority ethnic groups) were recruited from 31 clusters. At 12 months, there was no difference in mean change in HbA1c between the two groups (?0.10%; (95% CI: ?0.37, 0.17). Subgroup analyses suggested the intervention was effective at lowering HbA1c in White European compared with ethnic minority groups. The intervention group lost more body weight than the control group (?0.82 kg at 6 months and ?1.06 kg at 12 months; both p = 0.03).ConclusionOverall, the programme did not result in HbA1c improvement but in subgroup analysis, a beneficial effect occurred in White Europeans. Findings emphasise a need to develop and evaluate culturally-relevant programmes for ethnic minority groups.     

Life expectancy following a cardiovascular event in individuals with and without type 2 diabetes: A UK multi-ethnic population-based observational study

Background and aimsWe aimed to evaluate the life expectancy following the first cardiovascular disease (CVD) event by type 2 diabetes (T2D) status and ethnicity.Methods and resultsWe used the Clinical Practice Research Datalink database in England (UK), linked to the Hospital Episode Statistics information, to identify individuals with and without T2D who survived a first CVD event between 1st Jan 2007 and 31st Dec 2017; subsequent death events were extracted from the Office for National Statistics database. Ethnicity was categorised as White, South Asian (SA), Black, or other. Flexible parametric survival models were used to estimate survival and predict life expectancy. 59,939 individuals with first CVD event were included: 7596 (12.7%) with T2D (60.9% men; mean age at event: 69.7 years [63.2 years in SA, 65.9 in Black, 70.2 in White]) and 52,343 without T2D (56.7% men; 65.9 years [54.7 in Black, 58.2 in SA, 66.3 in White]). Accounting for potential confounders (sex, deprivation, lipid-lowering medication, current smoking, and pre-existing hypertension), comparing individuals with vs without T2D the mortality rate was 53% higher in White (hazard ratio [HR]: 1.53 [95% CI: 1.44, 1.62]), corresponding to a potential loss of 3.87 (3.30, 4.44) life years at the age of 50 years in individuals with T2D. No evidence of a difference in life expectancy was observed in individuals of SA (HR: 0.82 [0.52, 1.29]; −1.36 [-4.58, 1.86] life years), Black (HR: 1.26 [0.59, 2.70]; 1.21 [-2.99, 5.41] life years); and other (HR: 1.64 [0.80, 3.39]; 3.89 [-2.28, 9.99] life years) ethnic group.ConclusionFollowing a CVD event, T2D is associated with a different prognosis and life years lost among ethnic groups.     

Inequalities in enrollment of women and racial minorities in trials testing uric acid lowering drugs

AimsWe investigated sex and racial inequalities in clinical trials testing serum uric acid (SUA) lowering drugs and analyzed the temporal trends of participation among the pre-specified demographic groups.Data were collected from publications of clinical trials testing SUA-lowering drugs. Linear regression analysis was performed to assess the relation between drug approval year and proportion of women and minorities enrolled in clinical studies.Data synthesisThe mean percentage enrollment of women in clinical trials significantly decreased over the time (r = −0.43, P-value = 0.02). Moreover, there was a statistically significant difference in mean percentage enrollment of women among trials testing different SUA-lowering drugs, with the highest representation in rasburicase (71.1%) and the lowest representation of women in dotinurad (0.8%). Over the time, also the mean percentage enrollment of racial minorities decreased, passing from 8.7% to 2.2% in a 10-year period.Women were proportionally underrepresented compared with their share of the population with asymptomatic hyperuricemia, overall (participation-to-prevalence ratio (PPR) = 0.34), in trials testing xanthine oxiase inhibitors (PPR = 0.38) and uricosurics (PPR = 0.29), and in trials with febuxostat, allopurinol, pegloticase, halofenate/arhalofenate, verinurad, lesinurad and dotinurad. Women were proportionally underreppresented also compared with their share of the population with gout, overall (PPR = 0.69) and in trials testing XOIs (PPR = 0.69), uricosurics (PPR = 0.68), and all SUA-lowering drugs excepted for rasburicase, pegloticase and topiroxostat.ConclusionsOur analysis shows that women and racial and ethnical minorities are underrepresented in controlled clinical trials testing SUA-lowering drugs, with similar pattern across drug classes.     

Computerized tomography scan in pre-diagnostic pancreatic ductal adenocarcinoma: Stages of progression and potential benefits of early intervention: A retrospective study

BackgroundThe frequency, nature and timeline of changes on thin-slice (≤3 mm) multi-detector computerized tomography (CT) scans in the pre-diagnostic phase of pancreatic ductal adenocarcinoma (PDAC) are unknown. It is unclear if identifying imaging changes in this phase will improve PDAC survival beyond lead time.MethodsFrom a cohort of 128 subjects (Cohort A) with CT scans done 3–36 months before diagnosis of PDAC we developed a CTgram defining CT Stages (CTS) I through IV in the radiological progression of pre-diagnostic PDAC. We constructed Cohort B of PDAC resected at CTS I and II and compared survival in CTS I and II in Cohort A (n = 22 each; control natural history cohort) vs Cohort B (n = 33 and 72, respectively; early interception cohort).ResultsCTs were abnormal in 16% and 85% at 24–36 and 3–6 months respectively, before PDAC diagnosis. The PDAC CTgram stages, findings and median lead times (months) to clinical diagnosis were: CTS I: Abrupt duct cut-off/duct dilatation (−12.8); CTS II: Low density mass confined to pancreas (−9.5), CTS III: Peri-pancreatic infiltration (−5.8), CTS IV: Distant metastases (only at diagnosis). PDAC survival was better in cohort B than in cohort A despite inclusion of lead time in Cohort A: CTS I (36 vs 17.2 months, p = 0.03), CTS II (35.2 vs 15.3 months, p = 0.04).ConclusionStarting 12–18 months before PDAC diagnosis, progressive and increasingly frequent changes occur on CT scans. Resection of PDAC at the time of pre-diagnostic CT changes is likely to provide survival benefit beyond lead time.     

In the Era of Direct-Acting Antivirals,Liver Transplant Delisting Due to Clinical Improvement for Hepatitis C Remains Infrequent

Background / AimsStudies have suggested marked increases in transplant delisting due to clinical improvement for patients with hepatitis C virus (HCV) associated cirrhosis in the era of direct acting antivirals (DAAs). This study provides a ‘real world’ assessment of waitlist dynamics for HCV transplant candidates in the current era.MethodsThis was a retrospective cohort study of adults waitlisted for liver transplant (LT) alone between 1/1/2005-12/31/2018 using national US data. The post-DAA era included all listings occurring after 1/1/2013. Temporal trends in waitlisting, patient characteristics and outcomes with decompensated cirrhosis were evaluated. Adjusted competing risks models assessed the interaction of DAA-era and HCV history on (i) waitlist mortality, and (ii) delisting due to clinical improvement.ResultsOverall listing rates for HCV patients have decreased in the DAA era and particularly with Model for End-stage Liver Disease score ≥15 and ≥30. Rates of refractory ascites and severe encephalopathy at listing have increased. Delisting due to clinical improvement remains low (6.1% for 2013-2017 versus 5.2% for 2009-2012 versus 4% for 2005-2008; p < .001) and, for many, ascites (46.5%) and encephalopathy (30.5%) persist at delisting. Waitlist recovery is more frequent for HCV patients post-DAA (adjusted SHR 1.78 vs pre-DAA, 95% CI: 1.58-2.02; p < .001), while improvements in waitlist mortality by era are similar to non-HCV candidates (adjusted SHR 0.74 [95% CI: 0.7-0.78; p < .001] and 0.77 [95% CI: 0.74-0.8; p < .001], respectively).ConclusionListing rates for decompensated HCV cirrhosis have decreased in the DAA era. Delisting of HCV patients for clinical improvement has increased, but remains infrequent and many continue to experience considerable morbidity.     

Triglyceride glucose index and carotid atherosclerosis incidence in the Chinese population: A prospective cohort study

Background and aimsThe association of the triglyceride glucose (TyG) index with carotid atherosclerosis has not been reported in longitudinal studies. The present study aimed to investigate whether the TyG index increases the risk of carotid atherosclerosis incidence.Methods and resultsThis study included data from the Beijing Health Management Cohort (BHMC; n = 6955) and the Beijing Physical Examination Cohort (BPEC; n = 8473). Participants without a history of carotid atherosclerosis who underwent health examination in 2011 or 2012 were annually followed until 2019. The TyG index was denoted as ln [triglycerides (mmol/L)1fasting glucose (mmol/L)/2]. During a median follow-up of 5.02 years and 5.36 years, 1441 individuals in the BHMC group and 2181 individuals in the BPEC group developed carotid plaque, respectively. The adjusted hazard ratios (HRs) of the continuous TyG index were 1.253 (95% CI, 1.044 to 1.505) and 1.252 (95% CI, 1.091 to 1.437) for the BHMC and BPEC groups, respectively. Individuals in the highest quartile of the TyG index were associated with an increased risk of carotid plaque compared with those in the lowest quartile (BHMC: HR, 1.366; 95% CI, 1.101 to 1.695, P for trend = 0.010; BPEC: HR, 1.379; 95% CI, 1.196 to 1.591, P for trend = 0.013).ConclusionThese findings suggested that a higher TyG index increases the risk of carotid atherosclerosis incidence in the general population.     

Neighborhood-Level Factors Contribute to Disparities in Hepatocellular Carcinoma Incidence in Texas

Background and AimsTexas has the highest hepatocellular carcinoma (HCC) incidence rates in the continental United States, but these rates vary by race-ethnicity. We examined racial-ethnic disparities through a geospatial analysis of the social determinants of health.MethodsUsing data from the Texas Cancer Registry, we assembled 11,547 HCC cases diagnosed between 2011 and 2015 into Texas’s census tracts geographic units. Twenty-nine neighborhood measures representing demographics and socioeconomic, and employment domains were retrieved from the U.S. Census Bureau. We performed a series of aspatial and spatially weighted regression models to identify neighborhood-level characteristics associated with HCC risk.ResultsWe found positive associations between HCC and proportion of population in census tracts that are Black or African American, Hispanic, over 60 years of age, in the construction industry, and in the service occupation but an inverse association with the proportion of population employed in the agricultural industry. The magnitude of these associations varied across Texas census tracts.ConclusionsWe found evidence that neighborhood-level factors are differentially associated with variations in HCC incidence across Texas. Our findings reinforce existing knowledge about HCC risk factors and expose others, including neighborhood-level employment status.     

Race- and sex-specific association between alcohol consumption and hypertension in 22 cohort studies: A systematic review and meta-analysis

Background and aimsThe alcohol–hypertension relation has been well documented, but whether women have protective effect or race and type of beverage consumed affect the association remain unclear. To quantify the relation between total or beverage-specific alcohol consumption and incident hypertension by considering the effect of sex and race.Methods and resultsArticles were identified in PubMed and Embase databases with no restriction on publication date. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were calculated by random effects models. Restricted cubic splines were used to model the dose–response association. This study involved 22 articles (31 studies) and included 414,477 participants. The hypertension risk was different among liquor, wine, and beer at 5.1–10 g/d of ethanol consumption (P_{-across subgroups} = 0.002). The hypertension risk differed between men (RR: 1.14, 95% CI: 1.07, 1.20) and women (RR: 0.98, 95% CI: 0.89, 1.06) at 10 g/d (P_{-across subgroups} = 0.005). We found a linear alcohol–hypertension association among white (P-_linearity = 0.017), black people (P-_linearity = 0.035), and Asians (P-_linearity<0.001). With 10 g/d increment of consumption, the RRs for hypertension were 1.06 (95% CI: 1.04, 1.08), 1.14 (95% CI: 1.01, 1.28), and 1.06 (95% CI: 1.01, 1.10) for Asians, black, and white people, respectively.ConclusionSex modifies the alcohol–hypertension association at low level of alcohol consumption and we did not find evidence of a protective effect of alcohol consumption among women. Black people may have higher hypertension risk than Asians and white people at the same ethanol consumption.     

Incidence of Malignancies in Patients Treated With Sirolimus Following Heart Transplantation

BackgroundMalignancy is a major cause of late post-heart transplantation (HT) mortality. Sirolimus (SRL) exerts antiproliferative properties and its long-term use in HT as primary immunosuppression (IS) is associated with decreased mortality risk that is not fully explained by attenuation of cardiac allograft vasculopathy progression.ObjectivesThis study sought to examine whether conversion from calcineurin inhibitor (CNI)-based to SRL-based IS was associated with decreased risk of malignancy post-HT.MethodsOverall, 523 patients underwent HT between 1994 and 2016 at a single institution. The main outcomes included incidence of overall de novo malignancies (excluding non-melanoma skin cancers [NMSCs]), post-transplantation lymphoproliferative disorders (PTLD), and first and subsequent primary occurrences of NMSC post-HT.ResultsThe study identified 307 patients on SRL-based and 216 on CNI-based maintenance IS. Over a median follow-up of 10 years after HT, overall de novo malignancies (non-NMSC) occurred in 31% of CNI patients and in 13% of SRL patients (adjusted hazard ratio [HR]: 0.34; 95% confidence interval [CI]: 0.18 to 0.62; p < 0.001). The incidence of the first NMSC was similar in the SRL and CNI groups (HR: 0.92; 95% CI: 0.66 to 1.28; p = 0.62). However, conversion to SRL was significantly associated with a decreased risk of subsequent primary occurrences of NMSC compared with that of CNI (adjusted HR: 0.44; 95% CI: 0.28 to 0.69; p < 0.001). The adjusted PTLD risk was significantly decreased in the SRL group (HR: 0.13; 95% CI: 0.03 to 0.59; p = 0.009). Late survival post-HT was markedly decreased in patients who developed non-NMSC, PTLD, or non-PTLD compared with patients who did not develop these malignancies, whereas NMSC had no significant effect on survival.ConclusionsConversion to SRL was associated with a decreased risk of all de novo malignancies, PTLD, and subsequent primary occurrences of NMSC after HT. These findings provided further explanation of the late survival benefit with long-term SRL use.     

Racial and Ethnic Differences in Treatment and Outcomes of Severe Aortic Stenosis: A Review

Aortic stenosis (AS) is among the most common valvular heart diseases encountered in the United States. In this review the authors examine differences between racial and ethnic groups in the epidemiology and management of severe AS, explore potential explanations for these findings, and discuss the implications for improving the delivery of care to racially and ethnically diverse populations. Underrepresented racial and ethnic groups experience a paradoxically lower prevalence or incidence of AS relative to white subjects, despite having a higher prevalence of traditional risk factors. Historically, UREGs with severe AS have had lower rates of both surgical and transcatheter aortic valve replacement and experienced more post-surgical complications, including, bleeding, worsening heart failure, and rehospitalization. Last, UREGs with severe AS have an increased risk for morbidity and mortality relative to white patients. To date much of the research on AS has examined black-white differences, so there is a need to understand how other racial and ethnic groups with severe AS are diagnosed and treated, with examination of their resulting outcomes. Overall, racial and ethnic disparities in health care access and care delivery are a public health concern given the changing demographics of the U.S. population. These differences in AS management and outcomes highlight the need for additional research into contributing factors and appropriate interventions to address the lower rates of aortic valve replacement and higher morbidity and mortality among UREGs.     

Outcomes of patients undergoing elective liver and pancreas cancer surgery during the SARS-CoV-2 pandemic: an international,multicentre, prospective cohort study

BackgroundThe effect of SARS-CoV-2 infection upon HPB cancer surgery perioperative outcomes is unclear. Establishing risk is key to individualising treatment pathways.We aimed to identify the mortality rate and complications risk for HPB cancer elective surgery during the pandemic.MethodsInternational, prospective, multicentre study of consecutive adult patients undergoing elective HPB cancer operations during the initial SARS-CoV-2 pandemic. Primary outcome was 30-day perioperative mortality. Secondary outcomes included major and surgery-specific 30-day complications. Multilevel cox proportional hazards and logistic regression models estimated association of SARS-CoV-2 and postoperative outcomes.ResultsAmong 2038 patients (259 hospitals, 49 countries; liver n = 1080; pancreas n = 958) some 6.2%, n = 127, contracted perioperative SARS-CoV-2. Perioperative mortality (9.4%, 12/127 vs 2.6%, 49/1911) and major complications (29.1%, 37/127 vs 13.2%, 253/1911) were higher with SARS-CoV-2 infection, persisting when age, sex and comorbidity were accounted for (HR survival 4.15, 95% CI 1.64 to 10.49; OR major complications 3.41, 95% CI 1.72 to 6.75). SARS-CoV-2 was associated with late postoperative bleeding (11.0% vs 4.2%) and grade B/C postoperative pancreatic fistula (17.9% vs 8.6%).ConclusionSARS-CoV-2 infection was associated with significantly higher perioperative morbidity and mortality. Patients without SARS-CoV-2 had acceptable morbidity and mortality rates, highlighting the need to protect patients to enable safe ongoing surgery.     

Functional Mitral Regurgitation Outcome and Grading in Heart Failure With Reduced Ejection Fraction

ObjectivesThis study aims to define excess-mortality linked to functional mitral regurgitation (FMR) quantified in routine-practice.BackgroundAppraisal of FMR in heart failure with reduced ejection fraction (HFrEF) is challenging because risks of excess mortality remain uncertain and guidelines diverge.MethodsCases of HFrEF (ejection-fraction <50%) Stage B-C that were diagnosed between 2003 and 2011 and had routine-practice FMR quantitation (FMR cohort, n = 6,381) were analyzed for excess mortality thresholds/rates within the cohort and in comparison to the general population. These were also compared to those of a degenerative mitral regurgitation (DMR) simultaneous cohort (DMR cohort, n = 2,416).ResultsIn the FMR cohort (age: 70 ± 11 years, ejection fraction: 36 ± 10%, effective regurgitant orifice area [EROA]: 0.09 ± 0.13 cm²), EROA distribution was skewed towards low-values (≥0.40 cm² in only 8% vs 38% for the DMR cohort; P < 0.0001). One-year mortality was high (15.6%), increasing steeply from 13.3% without FMR to 28.5% with EROA ≥0.30 cm² (adjusted odds ratio: 1.57 [95% CI: 1.19-2.97]; P = 0.001). In the long term, 3,538 FMR cohort patients died with excess mortality threshold ∼0.10 cm² (vs ∼0.20 cm² in the DMR cohort), with 0.10 cm² EROA increments independently associated with considerable mortality increment (adjusted HR: 1.11 [95% CI: 1.08-1.15]; P < 0.0001) and with no detectable interaction. Compared to the general population, FMR excess mortality increased exponentially with higher EROA (risk ratio point estimates 2.8, 3.8, and 5.1 at EROA 0.20, 0.30, and 0.40 cm², respectively), and was much steeper than that of the DMR cohort (P < 0.0001). In nested models, individualized EROA was the strongest FMR survival marker, and a new expanded FMR grading scale based on 0.10 cm² EROA increments provided incremental power over current American Heart Association–American College of Cardiology/European Society of Cardiology guidelines (all P < 0.03).ConclusionsIn HFrEF, FMR is skewed towards smaller EROA. Nevertheless, when measured in routine practice, EROA is the strongest independent FMR determinant of survival after diagnosis. Excess mortality increases exponentially above the threshold of 0.10 cm², with a much steeper slope than in DMR, for any EROA increment. An expanded EROA-based stratification, superior to existing grading schemes in determining survival, should allow guideline harmonization.     

Spontaneous portosystemic shunt embolization in liver transplant recipients with recurrent hepatic encephalopathy

Introduction and objectivesSpontaneous portosystemic shunts (SPSS) are a common cause of recurrent hepatic encephalopathy (HE). Shunt occlusion is an effective and safe procedure when performed in patients with cirrhosis and preserved liver function. We aimed to describe our experience with SPSS embolization after liver transplantation (LT).PatientsWe identified five patients who underwent SPSS embolization after LT. Clinical, biochemical and technical procedure data were collected.ResultsAt presentation, all patients had developed graft cirrhosis and HE after LT. Median Model for End-stage Liver Disease (MELD) at embolization was 9 (range 7-12), median Child-Pugh was 8 (range 7-9). Splenorenal and mesocaval shunt were the most frequent types of SPSS found. Three patients have been completely free of HE. Of the two patients who had HE recurrence after embolization, one patient had two episodes of HE which was controlled well with medications. The other patient required three embolizations because of recurrent HE. Median follow-up was 4.4 years (range 1.0-5.0) and MELD score at last follow up was 13 (range 10-18) and median Child-Pugh score B, 7 points (range 5-12).ConclusionsSPSS can be considered as a cause of HE after LT. SPSS embolization is feasible and safe in LT recipients.     

Healthcare resource utilization and costs of nonalcoholic steatohepatitis patients with advanced liver disease in Italy

Background and aimsNonalcoholic steatohepatitis (NASH) may progress to advanced liver disease (AdvLD). This study characterized comorbidities, healthcare resource utilization (HCRU) and associated costs among hospitalized patients with AdvLD due to NASH in Italy.Methods and resultsAdult nonalcoholic fatty liver disease (NAFLD)/NASH patients from 2011 to 2017 were identified from administrative databases of Italian local health units using ICD-9-CM codes. Development of compensated cirrhosis (CC), decompensated cirrhosis (DCC), hepatocellular carcinoma (HCC), or liver transplant (LT) was identified using first diagnosis date for each severity cohort (index-date). Patients progressing to multiple disease stages were included in >1 cohort. Patients were followed from index-date until the earliest of disease progression, end of coverage, death, or end of study. Within each cohort, per member per month values were annualized to calculate all-cause HCRU or costs(€) in 2017.Of the 9,729 hospitalized NAFLD/NASH patients identified, 97% were without AdvLD, 1.3% had CC, 3.1% DCC, 0.8% HCC, 0.1% LT. Comorbidity burden was high across all cohorts. Mean annual number of inpatient services was greater in patients with AdvLD than without AdvLD. Similar trends were observed in outpatient visits and pharmacy fills. Mean total annual costs increased with disease severity, driven primarily by inpatient services costs.ConclusionNAFLD/NASH patients in Italy have high comorbidity burden. AdvLD patients had significantly higher costs. The higher prevalence of DCC compared to CC in this population may suggest challenges of effectively screening and identifying NAFLD/NASH patients. Early identification and effective management are needed to reduce risk of disease progression and subsequent HCRU and costs.     

Uptake and effectiveness of a primary cardiovascular prevention program in an underserved multiethnic urban community

Background and aimsCardiometabolic risk is increased among disadvantaged people and ethnic minorities. Paradoxically, their uptake of primary cardiovascular prevention is relatively low. New strategies are needed to tackle this public health problem. Aims of this study were to assess the uptake (as well as its determinants) and effectiveness of a primary cardiovascular prevention program for communities devised to facilitate access of disadvantaged and inclusion of ethnic minorities in addition to providing a state-of-the-art interdisciplinary personalized care.Methods and resultsSingle center, hospital-based, open study. All the residents in an underserved multiethnic urban community aged 40–65 years (n = 1646, 43.6% immigrants) were proactively invited by post mail to participate in a cardiovascular prevention program and different approaches were adopted to promote accessibility and inclusiveness. Program uptake was 23% and individual features independently associated with program uptake were status of immigrant (OR [CI 95%]: 3.6 [2.6–5.1]), higher educational level (3.6 [2.8–4.7]), and female gender (1.6 [1.2–2.1]). Retention was 82% at 6 months and 69% at 12 months. A predefined outcome of global cardiovascular risk improvement at 12 months in subjects with glycaemia >126 mg/dl, LDL-C >115 mg/dl, systolic blood pressure ≥140 mmHg or BMI >28 at baseline was reached in 35%, 33%, 37% and 7% of the patients, respectively. 20% of smokers quitted and significant favorable changes were reported in diet quality, anxiety, depression and physical activity.ConclusionAccess inequalities to effective prevention may be counteracted, but increasing global uptake requires further upstream sensitization and awareness actions.Registered in ClinicalTrials.govNCT03129165.     

The Mitral Annular Disjunction of Mitral Valve Prolapse: Presentation and Outcome

ObjectivesThe aim of this study was to assess in patients with mitral valve prolapse (MVP) mitral annular disjunction (MAD) prevalence, phenotypic characteristics, and long-term outcomes (clinical arrhythmic events and excess mortality).BackgroundClinical knowledge regarding MAD of MVP remains limited and controversial, and its potential link with untoward outcomes is unsubstantiated.MethodsA cohort of 595 (278 women, mean age 61 ± 16 years) consecutive patients with isolated MVP, with comprehensive clinical, rhythmic, Doppler echocardiographic, and consistent MAD assessment, were examined. MAD prevalence, associated MVP phenotypes, and outcomes (survival, clinical arrhythmic events) starting at diagnostic echocardiography were analyzed. To balance important baseline differences, propensity scoring matching was conducted among patients with and those without MAD.ResultsThe presence of MAD was common (n = 186 [31%]) in patients with MVP, generally in younger patients, and was not random but was independently associated with severe myxomatous disease involving bileaflet MVP and marked leaflet redundancy (both P ≤ 0.0002). The presence of MAD was also independently associated with a larger left ventricle (P = 0.005). Age-matched cohort survival after MVP diagnosis was not worse with MAD (10-year survival 93% ± 2% for patients without MAD and 97% ± 1% for those with MAD; P = 0.40), even adjusted comprehensively for MVP characteristics (P = 0.80) and accounting for time-dependent mitral surgery (P = 0.60). During follow-up, 170 patients had clinical arrhythmic events (ventricular tachycardia, n = 159; arrhythmia ablation, n = 14; cardioverter-defibrillator implantation, n = 14; sudden cardiac death, n = 3). MAD was independently associated with higher risk for arrhythmic events (adjusted HR: 2.60; 95% CI: 1.87-3.62; P < 0.0001). The link between MAD and arrhythmic events persisted with time-dependent mitral surgery (adjusted HR: 2.54; 95% CI: 1.84-3.50; P < 0.0001), was strong under medical management (adjusted HR: 3.21; 95% CI: 2.03-5.06; P < 0.0001) but was weaker after mitral surgery (adjusted HR: 2.07; 95% CI: 1.24-3.43; P = 0.005).ConclusionsThis large cohort with MVP comprehensively characterized shows that MAD is frequent at MVP diagnosis and is strongly linked to advanced myxomatous degeneration. The presence of MAD was independently associated with long-term excess incidence of clinical arrhythmic events. However, within the first 10 years post-diagnosis, MAD was not linked to excess mortality, and although reassurance should be provided from the survival point of view, careful monitoring for arrhythmias is in order for MAD.
