Long-term effects of lowering postprandial glucose level on cardiovascular outcomes in early-stage diabetic patients with coronary artery disease: 10-year post-trial follow-up analysis of the DIANA study

AimsTo elucidate the long-term cardiovascular benefit of lowering postprandial hyperglycemia (PPG) in early-stage T2DM patients.MethodsThis 10-year post-trial follow-up study included 243 patients from the DIANA (DIAbetes and diffuse coronary Narrowing) study, a multi-center randomized controlled trial which compared the efficacy of one-year life-style and pharmacological (voglibose/nateglinide) intervention lowering PPG on coronary atherosclerosis in 302 early-stage T2DM subjects [impaired glucose tolerance (IGT) or newly-diagnosed T2DM] (UMIN-CTRID#0000107). MACE (all-cause death, non-fatal MI or unplanned coronary revascularization) were compared in (1) three assigned therapies (life-style intervention/vogliose/nateglinide) and (2) patients with and without improvement of PPG (reversion from IGT to NGT or from DM to IGT/NGT on 75 g oral glucose tolerance test).ResultsDuring the 10-year post-trial observational period, voglibose (HR = 1.07, 95%CI: 0.69–1.66, p = 0.74) or nateglinide (HR = 0.99, 95%CI: 0.64–1.55, p = 0.99) did not reduce MACE. Similarly, achieving the improvement of PPG was not associated with a reduction of MACE (HR = 0.78, 95%CI: 0.51–1.18, p = 0.25). However, in IGT subjects (n = 143), this glycemic management significantly reduced the occurrence of MACE (HR = 0.44, 95%CI: 0.23–0.86, p = 0.01), especially unplanned coronary revascularization (HR = 0.46, 95%CI: 0.22–0.94, p = 0.03).ConclusionsThe early improvement of PPG significantly reduced MACE and unplanned coronary revascularization in IGT subjects during the post-trial 10-year period.     

Association between body mass index and mortality in atrial fibrillation patients with and without diabetes mellitus: Insights from a multicenter registry study in China

Background and aimsThe aim of this study was to evaluate the association between body mass index (BMI) and mortality in atrial fibrillation (AF) patients with and without diabetes mellitus (DM).Methods and resultsA total of 1991 AF patients were enrolled and divided into two groups according to whether they have DM at recruitment. Baseline information was collected and a mean follow-up of 1 year was carried out. The primary outcome was defined as all-cause mortality with the secondary outcomes including cardiovascular mortality, stroke and major adverse events (MAEs). Univariable and multivariable Cox regression were performed to estimate the association between BMI and 1-year outcomes in AF patients with and without DM. 309 patients with AF (15.5%) had comorbid DM at baseline. Patients with DM were more likely to have cardiovascular comorbidities, receive relevant medications but carry worse 1-year outcomes. Multivariable Cox regressions indicated that elevated BMI was related with reduced risk of all-cause mortality, cardiovascular mortality and major adverse events. Compared to normal weight, overweight [HR (95% CI): 0.548 (0.405–0.741), p < 0.001] and obesity [HR (95% CI): 0.541 (0.326–0.898), p = 0.018] were significantly related with decreased all-cause mortality for the entire cohort. Remarkably reduced all-cause mortality in the overweight [HR (95% CI): 0.497 (0.347–0.711), p < 0.001] and obesity groups [HR (95% CI): 0.405 (0.205–0.800), p = 0.009] could also be detected in AF patients without DM, but not in those with DM.ConclusionElevated BMI was associated with reduced mortality in patients with AF. This association was modified by DM. The obesity paradox confined to AF patients without DM, but could not be generalized to those with DM.     

Invasive versus conservative management in spontaneous coronary artery dissection: A meta-analysis and meta-regression study

BackgroundData regarding the best treatment for spontaneous coronary artery dissection (SCAD) are limited. The aim of the present study was to compare the clinical outcomes of conservative versus invasive treatment in SCAD patients.MethodsWe systematically searched the literature for studies evaluating the comparative efficacy and safety of invasive revascularization versus medical therapy for the treatment of SCAD from 1990 to 2020. The study endpoints were all-cause death, cardiovascular death, myocardial infarction, heart failure, SCAD recurrence and target vessel revascularization (TVR) rates. Random effect meta-analysis was performed by comparing the clinical outcomes between the two groups. A univariate meta-regression analysis was also performed.ResultsTwenty-four observational studies with 1720 patients were included. After 28 ± 14 months, a conservative approach was associated with lower TVR rate compared with invasive treatment (OR = 0.50; 95%CI 0.28–0.90; P = 0.02). No statistical difference was found regarding all-cause death (OR = 0.81; 95%CI 0.31–2.08; P = 0.66), cardiovascular death (OR = 0.89; 95%CI 0.15–5.40; P = 0.89), myocardial infarction (OR = 0.95; 95%CI 0.50–1.81; P = 0.87), heart failure (OR 0.96; 95%CI 0.41–2.22; P = 0.92) and SCAD recurrence (OR = 0.94; 95%CI 0.52–1.72; P = 0.85). The meta-regression analysis suggested that male gender, diabetes mellitus, smoking habit, prior coronary artery disease, left main coronary artery involvement, lower ejection fraction and low TIMI flow at admission were related with high overall mortality, whereas SCAD recurrence was higher among patients with fibromuscular dysplasia.ConclusionsA conservative approach was associated with similar clinical outcomes and lower TVR rates compared with an invasive strategy in SCAD patients; future prospective studies are needed to confirm these results.     

The impact of recipient and donor gender-match and mismatch on the post-liver transplant outcomes of patients with primary biliary cholangitis

Background & aimsIn this study, we evaluate the effects of donor gender on post-liver transplant (LT) prognosis. We specifically consider patients with primary biliary cholangitis (PBC).MethodsThe 2005 to 2019 UNOS transplant registry was used to select patients with PBC. The study cohort was stratified by donor gender. All-cause mortality and graft failure hazards were compared using iterative Cox regression analysis. Subanalyses were performed to evaluate gender mismatch on post-LT prognosis.ResultsThere were 1885 patients with PBC. Of these cases, 965 entries had male donors and 920 had female donors. Median follow-up was 4.82 (25–75% IQR 1.83–8.93) years. Having a male donor was associated with higher all-cause mortality (aHR 1.28 95%CI 1.03–1.58) and graft failure (aHR 1.70 95%CI 1.02–2.82). Corresponding incidence rates were also relatively increased. In the sub-analysis of female recipients (n = 1581), those with gender-mismatch (male donors, n = 769) were associated with higher all-cause mortality (aHR 1.41 95%CI 1.11–1.78) but not graft failure. In the male recipient subanalysis (n = 304), no associations were found between gender-mismatch (female donors, n = 108) and all-cause mortality or graft failure.ConclusionThis study shows that recipients who have male donors experienced higher rates of all-cause mortality following LT. This finding was consistent in the female recipient-male donor mismatch cohort.     

Angiographic Functional Scoring of Coronary Artery Disease Predicts Mortality in Patients With Severe Aortic Stenosis Undergoing TAVR

Background/purposeCoronary artery disease (CAD) is common in patients undergoing transcatheter aortic valve replacement (TAVR), although its prognostic significance is questionable. Significant CAD stratified using SYNTAX score (SS) has been associated with greater mortality, yet it is unknown whether the functional impact of CAD also impacts outcomes in this cohort. DILEMMA score (DS) is a validated angiographic functional scoring tool that correlates with fractional flow reserve and instantaneous wave-free ratio.This study sought to assess the functional impact of CAD on outcomes in patients undergoing TAVR for severe aortic stenosis (AS).Methods/materials229 patients were included in this analysis. Patients underwent angiographic DS and SS and were classified using predefined values. The primary endpoint was one-year all-cause mortality, with secondary endpoints of 30-day major adverse cardiac and cerebrovascular events (MACCE).ResultsThe mean age was 83.9 ± 0.5 years (55.0% female), with 11.8% all-cause mortality. CAD defined by ≥30% stenosis in any vessel was not associated with adverse outcomes (HR = 1.08, p = 0.84). However, the risk of one-year mortality was greater in patients with either SS > 9 (20.8% vs. 9.4%, HR 2.34, p = 0.03) or DS > 2 (18.4% vs. 8.5%, HR = 2.28, p = 0.03). Both scoring systems were also associated with 30-day MACCE (both p < 0.05). After multivariate adjustment, independent predictors of one-year mortality were DS > 2 (HR = 2.29, p = 0.04), left ventricular ejection fraction <50% (HR 2.66, p = 0.04) and COPD (HR 2.43, p = 0.04).ConclusionOur results demonstrate that angiographic functional scoring is independently predictive of both 12-month mortality and 30-day MACCE following TAVR.     

Malnutrition in patients with coronary artery disease: Prevalence and mortality in a 46,485 Chinese cohort study

Background and aimsMalnutrition is associated with poor prognosis in a wide range of illnesses. However, its long-term prognostic impact in general coronary artery disease (CAD) patients is not well known. We aim to report the prevalence and long-term mortality of malnutrition in the whole general population.Methods and resultsIn this retrospective cohort study, the controlling nutritional status (CONUT) score was applied to 46,485 consecutive patients undergoing coronary angiography (CAG) and diagnosed with CAD from January 2007 to July 2018. Patients were stratified as having no malnutrition (n = 19,780), mild (n = 21,092), moderate (n = 5286) and severe malnutrition (n = 327), based on CONUT score. Overall, mean age was 63.1 ± 10.7 years, and 75.8% of patients (n = 35,250) were male. 45.4% of patients were mildly malnourished and 12.1% were moderately or severely malnourished. During a median follow-up of 5.1 years (interquartile range: 3.0–7.7 years), 6093 (17.3%) patients died. After adjusting for confounders, malnutrition risk was associated with significantly increased risk for all-cause death (mild vs. normal, HR = 1.19,95% confidence interval [CI]: 1.12 to 1.28; moderate vs. normal, HR = 1.42,95% CI: 1.30 to 1.55; severe vs. Normal, HR = 1.95, 95% CI: 1.57 to 2.41) (p for trend<0.001). The similar result on all-cause mortality was also found in different subgroups stratified by gender, chronic kidney disease, anemia, percutaneous coronary intervention.ConclusionsMalnutrition is a common complication among patients with CAD, and is strongly associated with increased mortality. Further studies need to explore the efficacy of nutritional interventions on long-term prognosis among CAD patients.This study was registered at Clinicaltrials.gov as NCT04407936.     

Impact of metformin use on risk and mortality of hepatocellular carcinoma in diabetes mellitus

BackgroundThe views regarding the associations between metformin use and hepatocellular carcinoma (HCC) among diabetes mellitus (DM) patients are divisive. Thus we summarized all available published studies evaluating the relationship between metformin therapy and HCC survival and risk, and aim to conduct an updated meta-analysis study to more accurately clarify the association.MethodsWe searched for articles regarding impact of metformin use on risk and mortality of HCC in DM and published before April 2021 in databases (PubMed and Web of Science). We used STATA 12.0 software to compute odds ratios (ORs)/relative risks (RRs) or hazard ratios (HRs) and their 95% confidence intervals (CIs) to generate a computed effect size and 95% CI.ResultsThe present study showed that metformin use was associated with a decreased risk of HCC in DM with a random effects model (OR/RR = 0.59, 95% CI 0.51–0.68, I2 = 96.5%, p < 0.001). In addition, the study indicated that metformin use was associated with a decreased all-cause mortality of HCC in DM with a random effects model (HR = 0.74, 95% CI 0.66–0.83, I2 = 49.6%, p = 0.037).ConclusionIn conclusion, our studies support that the use of metformin in DM patients is significantly associated with reduced risk and all-cause mortality of HCC. And more prospective studies focusing on the metformin therapy as a protective factor for HCC are needed to verify the accuracy of the findings.     

Safety of coffee consumption after myocardial infarction: A systematic review and meta-analysis

Background and aimsThis systematic review aims to evaluate the impact of coffee consumption in patients with previous myocardial infarction (MI), in relation to all-cause and cardiovascular mortality, as well as other major cardiovascular events (MACE) such as stroke, heart failure, recurrent MI and sudden death.Methods and resultsMEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science Core Collection, SciELO Citation Database, Current Contents Connect®, KCI Korean Journal Database, African Index Medicus, and LILACS were searched for longitudinal studies evaluating the impact of coffee consumption in patients with previous myocardial infarction. We performed a random-effects meta-analysis to estimate the pooled hazard ratios (HR) with 95% confidence intervals (CI). The statistical heterogeneity was measured by I². A dose–response analysis was also conducted.Six prospective cohort studies were included in the primary meta-analysis. Consumption of coffee was associated with lower risk of cardiovascular mortality (HR = 0.70; 95% CI 0.54–0.91, I² = 0%; 2 studies) and was not associated with an increased risk of all-cause mortality (HR = 0.85; 95% CI 0.63–1.13; I² = 50%; 3 studies), recurrent MI (HR = 0.99; 95% CI 0.80–1.22; I² = 0%; 3 studies), stroke (HR = 0.97; 95% CI 0.63–1.49; I² = 39%; 2 studies) and MACE (HR = 0.96; 95% CI 0.86–1.07; I² = 0%; 2 studies). A significant non-linear inverse dose–response association was found for coffee consumption and all-cause mortality.ConclusionsConsumption of coffee was not associated with an increased risk of all-cause mortality and cardiovascular events in patients with previous myocardial infarction.     

Malnutrition status in patients of very advanced age with nonvalvular atrial fibrillation and its impact on clinical outcomes

Background and aimsMalnutrition is associated with adverse outcomes in patients with chronic disease. We screened malnutrition among patients of very advanced age with nonvalvular atrial fibrillation (AF) by malnutrition scores and investigated the associations between malnutrition and clinical outcomes.Methods and resultsThis retrospective observational study included 461 patients aged ≥80 years with nonvalvular AF. Malnutrition was screened using the Controlling Nutritional Status (CONUT), Prognostic Nutritional Index (PNI), and Geriatric Nutritional Risk Index (GNRI) scores. The primary endpoints were composite events, including thromboembolic events and all-cause death. Malnutrition was present in 62.9%, 5.0%, and 21.9% of patients according to the CONUT, PNI, and GNRI scores, respectively. During a median 27-month follow-up, 130 (28.2%) patients had composite events. Kaplan−Meier curves revealed that patients with moderate to severe malnutrition had the worst clinical outcomes (log-rank P < 0.05 for all scores). Multivariate Cox proportional hazards analysis showed that moderate to severe malnutrition was an independent predictor of composite events [hazard ratio (HR): 2.051, 95% confidence interval (95%CI): 1.143–3.679, P = 0.016 for CONUT score; HR: 3.374, 95%CI: 1.898–5.998, P < 0.001 for PNI score; HR: 2.254, 95%CI: 1.381–3.679, P = 0.001 for GNRI score]. Addition of the CONUT or GNRI score to a baseline prediction model for composite events significantly improved the net reclassification improvement and integrated discrimination improvement (all P < 0.05).ConclusionModerate to severe malnutrition was an independent predictor of adverse outcomes among patients of very advanced age with nonvalvular AF. Screening for malnutrition might provide useful information regarding prognosis and risk stratification.     

Influence of sex on long-term prognosis in patients with atrial fibrillation treated with oral anticoagulants. Results from the prospective,nationwide FANTASIIA study

BackgroundWhile many risk factors for Atrial Fibrillation (AF) have been identified, there are important differences in their relative impact between sexes. The aim of our study was to investigate the influence of sex as a long-term predictor of adverse events in “real world” AF patients treated with direct oral anticoagulants.MethodsThe FANTASIIA registry is a prospective, national and multicentric study including outpatients with anticoagulated AF patients. Baseline characteristics and adverse events at 3 years of follow-up were collected and classified by sex. Cox multivariate analysis was performed to investigate the role of sex in major events and composite outcomes.ResultsA total of 1956 patients were included in the study. 43.9% of them were women, with a mean age of 73.8 ± 9.4 years (women were older 76.5 ± 7.9 vs 71.7 ± 10.1, p<0.001). Women had higher rate of cardiovascular risk factors and higher mean of CHA₂DS₂-VASc (4.4 ± 1.4 vs 3.7 ± 1.6, p<0.001) and HAS-BLED (2.1 ± 1.0 vs 1.9 ± 1.1, p<0.001) than men. After 3 years of follow-up, rates of major events were similar in both groups with limit difference for all-cause mortality (4.4%/year in women vs 5.6%/year in men; p = 0.056). However, all the composite events were more frequent in women. We observed in the non-adjusted adverse events lower rate of all-cause mortality (HR 0.62, 95%CI 0.47–0.81; p<0.001), composite 1 outcomes (HR 0.80, 95%CI 0.65–0.98; p = 0.029) and composite 2 (HR 0.77, 95%CI 0.64–0.94; p = 0.010) in women compared with men. In multivariate Cox regression analysis observed that female sex was an independently protector factor for all-cause mortality and for the composite outcomes 1 and 2.ConclusionsIn this “real world” study of anticoagulated AF patients, women could have a protective role against development of adverse events, mainly on all-cause mortality and combined events.     

Compared impact of diabetes on the risk of heart failure from acute myocardial infarction to chronic coronary artery disease

AimWe attempted to describe the risk of heart failure (HF) occurrence according to diabetes mellitus (DM) status in patients with coronary artery disease (CAD) over time, from acute myocardial infarction (MI) to the chronic stable phase.MethodsFor the acute and subacute MI phases, we analysed the FAST-MI cohort restricted to patients without history of HF (n = 12,473). The analysis on 1-year outcomes after MI was further restricted to patients who were discharged alive and without history of HF and/or HF symptoms during the index hospitalisation for MI (n = 9181). To analyse the chronic phase, we analysed the CORONOR cohort restricted to patients without history of HF (n = 3871). The primary endpoint was HF occurrence according to DM status. We also analysed the composite of all-cause death or HF.ResultsKillip-Kimball class ≥II during the index MI hospitalisation was more frequent in DM patients compared to non-DM patients (29% vs. 15.3%, adjusted OR = 1.60). At one year after MI, hospitalisation for HF was more frequent in DM patients (3.3% vs. 1.2%, adjusted HR = 1.73). At the chronic phase (5-year outcomes), hospitalisation for HF was more frequent in DM patients (8.5% vs. 4.3%, adjusted HR = 1.70). Results focusing on the composite endpoint (all-cause death or HF) were consistent.ConclusionDM was associated with a very constant near 2-fold increase in the risk of HF whatever the presentation of CAD. Avoiding the risk of HF occurrence in CAD patients with DM is critical in daily practice and should be a constant life-long endeavour.     

Elevated serum uric acid and risk of cardiovascular or all-cause mortality in maintenance hemodialysis patients: A meta-analysis

Background and aimsStudies have shown inconsistent results about the association between serum uric acid (SUA) levels and mortality in hemodialysis patients. We performed this meta-analysis to determine whether higher SUA values comprised a risk factor of cardiovascular or all-cause mortality in maintenance hemodialysis patients.Methods and resultsPubmed, Embase and the Cochrane library were searched up to August 31, 2020 for the longitudinal studies that investigated the association between the elevated SUA and cardiovascular or all-cause mortality risk in maintenance hemodialysis patients. Pooled adjusted hazard ratios (HR) and corresponding 95% confidence interval (CI) were calculated using a random-effects model. We included 10 studies with an overall sample of 264,571 patients with hemodialysis in this meta-analysis. Patients with the highest SUA were associated with a decreased risk of cardiovascular mortality (HR = 0.72, 95% CI 0.59–0.87) compared with patients with the lowest SUA after adjustment for potential confounders in a random effects model. Moreover, for each increase of 1 mg/dl of SUA, the overall risks of all-cause and cardiovascular mortality decreased by 6% and 9%, respectively (HR = 0.94, 95% CI 0.90–0.99; HR = 0.91, 95% CI 0.89–0.94).ConclusionElevated SUA levels are strongly and independently associated with lower risk of cardiovascular mortality in maintenance hemodialysis patients. More designed studies, especially randomized controlled trials, should be conducted to determine whether high SUA levels is an independent risk factor of all-cause mortality in hemodialysis patients.     

Surgical Versus Transcatheter Aortic Valve Replacement in Patients With Malignancy

BackgroundPatients with aortic stenosis (AS) and malignancy experience poor clinical outcomes with challenging decisions regarding aortic valve replacement (AVR). We sought to compare the outcomes of transcatheter (TAVR) versus surgical (SAVR) AVR in patients with AS and malignancy.MethodsBased on the Nationwide Readmission Database, we compared all patients with malignancy who underwent isolated SAVR vs. TAVR in 2016 for severe AS. We performed univariate and multivariate analyses for baseline characteristics and clinical outcomes. A total of 2566 patients were included, 1952 (76%) had TAVR and the remaining 614 (24%) had isolated SAVR. Patients who underwent TAVR were older (82 vs 72 years, p < .001), had more metastasis (19 vs 14%, p = .004), heart failure (72% vs 34%, p < .001), coronary artery disease (72% vs 52%, p < .001), anemia (28% vs 22%, p = .006), chronic lung (30% vs 22%, p < .001) and renal disease (35% vs 14%, p < .001), and shorter length of stay (3 vs 7 days, p < .001).ResultsIn multivariate regression, TAVR and SAVR had similar in-patient mortality (HR = 1.08; 95%CI 0.61 ̶ 1.94) and 30-day readmission (HR = 1.26; 95%CI 0.95 ̶ 1.67). TAVR was associated with lower vascular complications (HR = 0.59; 95%CI 0.41 ̶ 0.86), acute deep venous thrombosis (HR = 0.25, 95%CI 0.1 ̶ 0.59), acute kidney injury (HR = 0.24, 95%CI 0.17 ̶ 0.33), blood transfusion (HR = 0.22, 95%CI 0.16 ̶ 0.3), cardiogenic shock (HR = 0.48, 95%CI 0.26 ̶ 0.89), and respiratory complications (HR = 0.26, 95%CI 0.2 ̶ 0.35).ConclusionsIn patients with malignancy, TAVR is a viable and safe option compared to SAVR with better clinical outcomes, especially thromboembolic events.     

ACOD frente a AVK en pacientes con fibrilación auricular y bioprótesis: revisión sistemática y metanálisis

Introduction and objectivesDirect oral anticoagulant (DOAC) therapy has been shown to be safe and effective in patients with atrial fibrillation (AF). However, outcomes in AF patients with bioprosthetic valves are unclear, as this population has been underrepresented in clinical trials. The aim of this study was to assess the safety and efficacy of DOACs in this population based on the existing published literature.MethodsA systematic search and review were conducted to identify randomized clinical trials and comparative observational studies published from 2017 to January 2022 that compared DOACs and vitamin K antagonists (VKAs) in AF patients with bioprosthetic valves. Hazard ratios (HR) were collected to compare the 2 treatments in terms of cardiovascular and all-cause mortality, stroke/systemic embolism, and major bleeding. A meta-analysis combining the results was performed.ResultsWe included 12 studies (30 283 patients). DOACs and VKAs were compared based on HRs at the 95% confidence interval. DOAC therapy was associated with a significant 9% reduction in all-cause mortality (HR, 0.91; 95%CI, 0.85-0.97; P = .0068; I² = 8%), with no significant differences in the risk of stroke/systemic embolism (HR, 0.87; 95%CI, 0.67-1.14; P = .29; I² = 45%) or major bleeding (HR, 0.82; 95%CI, 0.67-1.00; P = .054; I² = 48.7%).ConclusionsDOAC therapy in AF patients with bioprosthetic valves may be associated with a significant reduction in all-cause mortality, with no reduction in the efficacy of stroke/systemic embolism prevention or increase in major bleeding risk.     

Prediction of all-cause mortality with malnutrition assessed by nutritional screening and assessment tools in patients with heart failure：a systematic review

Background and aimsIn the absence of a gold standard or scientific consensus regarding the nutritional evaluation of heart failure (HF) patients, this study aimed to summarize and systematically evaluate the prognostic value of nutritional screening and assessment tools used for all-cause mortality in HF patients.Methods and resultsRelevant studies were retrieved from major databases (PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), WanFang Data, and China Biology Medicine disc (CMB)) and searched from the earliest available date until July 2021. If three or more studies used the same tool, meta-analysis using RevMan 5.3 was performed. This systematic review was registered at PROSPERO (number CRD42021275575). A total of 36 articles involving 25,141 HF patients were included for qualitative analysis and 31 studies for quantitative analysis. Meta-analysis of these studies indicated, poor nutritional status evaluated by using 5 nutritional screening tools (Prognostic Nutritional Index (PNI), Geriatric Nutritional Risk Index (GNRI), Controlling Nutritional Status Score (CONUT), Nutritional Risk Index (NRI), and Short Form Mini Nutritional Assessment (MNA-SF)) or 2 nutritional assessment tools (the Mini Nutritional Assessment (MNA) and Generated Subjective Global Assessment (SGA)) predicted all-cause mortality in HF patients. Of all tools analyzed, MNA had the maximum HR for mortality [HR = 2.62, 95%CI 1.11–6.20, P = 0.03] and MNA-SF [HR = 1.94, 95%CI 1.40–2.70, P＜0.001] was the best nutritional screening tools.ConclusionPoor nutritional status predicted all-cause mortality in HF patients. MNA may be the best nutritional assessment tool, and MNA-SF is most recommended for HF patient nutritional screening. The application value of MNA, especially in patients with reduced left ventricular ejection fraction (LVEF), needs to be further confirmed. The clinical application value of Mini-Nutrition Assessment Special for Heart Failure (MNA-HF) and Global Leadership Initiative on Malnutrition (GLIM) in HF patients needs to be confirmed.     

Inverse association between circulating vitamin D and mortality – Dependent on sex and cause of death?

Background and aimsIn various populations, vitamin D deficiency is associated with chronic diseases and mortality. We examined the association between concentration of circulating 25-hydroxyvitamin D [25(OH)D], a marker of vitamin D status, and all-cause as well as cause-specific mortality.Methods and ResultsThe study included 3404 participants of the general adult Swiss population, who were recruited between November 1988 and June 1989 and followed-up until the end of 2008. Circulating 25(OH)D was measured by protein-bound assay. Cox proportional hazards regression was used to examine the association between 25(OH)D concentration and all-cause and cause-specific mortality adjusting for sex, age, season, diet, nationality, blood pressure, and smoking status. Per 10 ng/mL increase in 25(OH)D concentration, all-cause mortality decreased by 20% (HR = 0.83; 95% CI 0.74–0.92). 25(OH)D concentration was inversely associated with cardiovascular mortality in women (HR = 0.68, 95% CI 0.46–1.00 per 10 ng/mL increase), but not in men (HR = 0.97; 95% CI 0.77–1.23). In contrast, 25(OH)D concentration was inversely associated with cancer mortality in men (HR = 0.72, 95% CI 0.57–0.91 per 10 ng/mL increase), but not in women (HR = 1.14, 95% CI 0.93–1.39). Multivariate adjustment only slightly modified the 25(OH)D-mortality association.Conclusion25(OH)D was similarly inversely related to all-cause mortality in men and women. However, we observed opposite effects in women and men with respect to cardiovascular and cancer mortality.     

Association between monocyte count to high-density lipoprotein cholesterol ratio and mortality in patients undergoing peritoneal dialysis

Background and aimsPrevious studies had demonstrated that elevated monocyte count to high-density lipoprotein cholesterol ratio (MHR), a novel marker of inflammation, was associated with higher cardiovascular events and mortality in patients with pre-dialysis chronic kidney disease, diabetes, and coronary heart disease. However, the association between MHR and mortality in patients undergoing peritoneal dialysis (PD) has received little attention. The aim of this study was to investigate the association between MHR and all-cause and cardiovascular mortality in PD patients.Methods and resultsIn this single center retrospective cohort study, PD patients who had catheter insertion in our PD center from January 1, 2006 to December 31, 2016 were enrolled. All patients were divided into three groups according to the tertiles of baseline MHR levels and followed up until December 31, 2018. The associations of MHR levels with all-cause and cardiovascular mortality were assessed by using Cox proportional hazards models. Of 1584 patients, mean age was 46.02 ± 14.65 years, 60.1% were male, and 24.2% had diabetes. The mean MHR level was 0.39 ± 0.23. During a median follow up time of 45.6 (24.6–71.8) months, 349 patients died, and 181 deaths were caused by cardiovascular disease. After adjusting for confounders, the highest MHR tertile was significantly associated with all-cause and cardiovascular mortality with a hazard ratio of 1.43 (95%CI = 1.06–1.93, P = 0.019), 1.54 (95%CI = 1.01–2.35, P = 0.046), respectively.ConclusionHigher MHR level was an independent risk factor for all-cause and cardiovascular mortality in PD patients.     

Efecto pronóstico diferencial de la diabetes mellitus tipo 2 en mujeres y varones con insuficiencia cardiaca y fracción de eyección conservada

Introduction and objectivesType 2 diabetes mellitus (DM2) is a common comorbidity in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Previous studies have shown that diabetic women are at higher risk of developing HF than men. However, the long-term prognosis of diabetic HFpEF patients by sex has not been extensively explored. In this study, we aimed to evaluate the differential impact of DM2 on all-cause mortality in men vs women with HFpEF after admission for acute HF.MethodsWe prospectively included 1019 consecutive HFpEF patients discharged after admission for acute HF in a single tertiary referral hospital. Multivariate Cox regression analysis was used to evaluate the interaction between sex and DM2 regarding the risk of long-term all-cause mortality. Risk estimates were calculated as hazard ratios (HR).ResultsThe mean age of the cohort was 75.6 ± 9.5 years and 609 (59.8%) were women. The proportion of DM2 was similar between sexes (45.1% vs 49.1%, P = .211). At a median (interquartile range) follow-up of 3.6 (1-4-6.8) years, 646 (63.4%) patients died. After adjustment for risk factors, comorbidities, biomarkers, echo parameters and treatment at discharge, multivariate analysis showed a differential prognostic effect of DM2 (P value for interaction = .007). DM2 was associated with a higher risk of all-cause mortality in women (HR, 1.77; 95%CI, 1.41-2.21; P < .001) but not in men (HR, 1.23; 95%CI, 0.94-1.61; P = .127).ConclusionsAfter an episode of acute HF in HFpEF patients, DM2 confers a higher risk of mortality in women. Further studies evaluating the impact of DM2 in women with HFpEF are warranted.Full English text available from:www.revespcardiol.org/en     

Sex Differences in the Long-term Prognosis of Dilated Cardiomyopathy

BackgroundDilated cardiomyopathy (DCM) represents a specific phenotype of heart failure. Sex differences in the long-term prognosis of patients with DCM are unknown. The aim of this study is to investigate the long-term prognostic role of gender in a large cohort of patients with DCM.MethodsA total of 1113 patients with DCM were prospectively enrolled. To investigate the impact of sex, a propensity score–matching analysis was performed on a sample of 586 patients. Univariable and multivariable Cox models and competing-risk analyses were estimated on both cohorts for the following outcome measures: (1) all-cause mortality/heart transplantation (HTx)/ventricular assist device (VAD); (2) cardiovascular mortality/HTx/VAD; and (3) sudden cardiac death or malignant ventricular arrhythmias.ResultsWomen were older than men (50 ± 15 years vs 47 ± 15 years, respectively, P = 0.004) and more frequently had moderate to severe left ventricular dilation (P < 0.001) and left bundle branch block (P = 0.019). At multivariable analyses, male sex was independently associated with all considered outcome measures in the total cohort. At propensity score–matching analysis, over a median follow-up of 126 months (interquartile range, 62-201), 96 men (33%) vs 66 women (22%) experienced all-cause mortality/HTx/VAD (P = 0.03), 95 men (32%) vs 57 women (20%) experienced cardiovascular mortality/HTx/VAD (P = 0.025), and 46 men (16%) vs 28 women (10%) experienced sudden cardiac death/malignant ventricular arrhythmias (P = 0.07).ConclusionThe long-term outcomes of women affected by DCM are more favourable than those of men, and sex emerged as an important independent factor, particularly for cardiovascular outcomes.
