Clinical Characteristics and Outcomes of Patients With Primary Plasma Cell Leukemia in the Era of Novel Agent Therapy

ObjectiveTo evaluate the clinical outcomes of patients with primary plasma cell leukemia (pPCL) defined by 5% or greater clonal circulating plasma cells on peripheral blood smear and treated with novel agent induction therapies.Patients and MethodsA cohort of 68 patients with pPCL diagnosed at the Mayo Clinic in Rochester, Minnesota, from January 1, 2000, to December 31, 2019, and treated with novel agent induction therapies was evaluated.ResultsThe median follow-up was 46 (95% CI, 41 to 90) months. The median bone marrow plasma cell content was 85% (range, 10% to 100%) and median clonal circulaitng plasma cell percentage on the peripheral blood smear was 26% (range, 5% to 93%). There was a preponderance of t(11;14) primary cytogenetic abnormality in this cohort. The median time to next therapy (TTNT) and overall survival (OS) for all patients with pPCL patients in this cohort was 13 (95% CI, 9 to 17) and 23 (95% CI, 19 to 38) months, respectively. However, when stratified by cytogenetic risk, the median TTNT and OS were 16 and 51 months for standard risk vs 9 and 19 months for high risk (P=.01 for OS).ConclusionPrimary plasma cell leukemia remains an aggressive disease with poor prognosis despite novel agent–based therapies. Some patients have better than expected survival and this phenomenon may be influenced by the absence of high-risk cytogenetics. Newer treatment regimens are needed to improve the prognosis of this devastating disease.     

Cardiac Abnormalities in COVID-19 and Relationship to Outcome

ObjectiveTo characterize the clinical and transthoracic echocardiographic features and 30-day outcomes of hospitalized patients with coronavirus disease 2019 (COVID-19).MethodsRetrospective cohort study that included consecutive inpatients with COVID-19 infection who underwent clinically indicated transthoracic echocardiography at 10 sites in the Mayo Clinic Health System between March 10 and August 5, 2020. Echocardiography was performed at bedside by cardiac sonographers according to an abbreviated protocol. Echocardiographic results, demographic characteristics, laboratory findings, and clinical outcomes were analyzed.ResultsThere were 179 patients, aged 59.8±16.9 years and 111 (62%) men; events within 30 days occurred in 70 (39%) patients, including prolonged hospitalization in 43 (24%) and death in 27 (15%). Echocardiographic abnormalities included left ventricular ejection fraction less than 50% in 29 (16%), regional wall motion abnormalities in 26 (15%), and right ventricular systolic pressure (RVSP) of 35 or greater mm Hg in 44 (44%) of 101 in whom it was measured. Myocardial injury, defined as the presence of significant troponin level elevation accompanied by new ventricular dysfunction or electrocardiographic abnormalities, was present in 13 (7%). Prior echocardiography was available in 36 (20%) patients and pre-existing abnormalities were seen in 28 (78%) of these. In a multivariable age-adjusted model, area under the curve of 0.81, prior cardiovascular disease, troponin level, D-dimer level, and RVSP were related to events at 30 days.ConclusionBedside Doppler assessment of RVSP appears promising for short-term risk stratification in hospitalized patients with COVID-19 infection undergoing clinically indicated echocardiography. Pre-existing echocardiographic abnormalities were common; caution should be exercised in attributing such abnormalities to the COVID-19 infection in this comorbid patient population.     

Bleeding in Patients With Gastrointestinal Cancer Compared With Nongastrointestinal Cancer Treated With Apixaban,Rivaroxaban, or Enoxaparin for Acute Venous Thromboembolism

ObjectiveTo compare the bleeding risk in patients with gastrointestinal (GI) cancer with that in patients with non-GI cancer treated with anticoagulation for acute cancer-associated venous thromboembolism (Ca-VTE).Patients and MethodsConsecutive patients with Ca-VTE seen at the Mayo Thrombophilia Clinic between March 1, 2013, and April 20, 2020, were observed prospectively to assess major bleeding and clinically relevant nonmajor bleeding (CRNMB).ResultsIn the group of 1392 patients with Ca-VTE, 499 (35.8%) had GI cancer including 272 with luminal GI cancer (lower GI, 208; upper GI, 64), 176 with pancreatic cancer, and 51 with hepatobiliary cancer. The rate of major bleeding and CRNMB in patients with GI cancer was similar to that in 893 (64.2%) patients with non-GI cancer treated with apixaban, rivaroxaban, or enoxaparin. Apixaban had a higher rate of major bleeding in luminal GI cancer compared with the non-GI cancer group (15.59 vs 3.26 per 100 person-years; P=.004) and compared with enoxaparin in patients with luminal GI cancer (15.59 vs 3.17; P=.04). Apixaban had a lower rate of CRNMB compared with rivaroxaban in patients with GI cancer (3.83 vs 9.40 per 100 person-years; P=.03). Patients treated with rivaroxaban in the luminal GI cancer group had a major bleeding rate similar to that of patients with non-GI cancer (2.04 vs 4.91 per 100 person-years; P=.37).ConclusionApixaban has a higher rate of major bleeding in patients with luminal GI cancer compared with patients with non-GI cancer and compared with enoxaparin in patients with luminal GI cancer. Rivaroxaban shows no increased risk of major bleeding in patients with GI cancer or luminal GI cancer compared with patients with non-GI cancer.Trial RegistrationClinicalTrials.gov identifier: NCT03504007.     

Right Ventricular Enlargement and Dysfunction Are Associated With Increased All-Cause Mortality in Hypertrophic Cardiomyopathy

ObjectiveTo assess whether right ventricular enlargement (RVE) and right ventricular dysfunction (RVD) adversely affect prognosis in hypertrophic cardiomyopathy (HCM).Patients and MethodsData were retrieved from Mayo Clinic’s prospectively collected HCM registry between January 1, 2000, and September 30, 2012. Right ventricle (RV) size and function were semiquantitatively categorized via echocardiography as normal (RV-Norm) versus abnormal (RV-Abn) (RVE or RVD). All-cause mortality was the primary endpoint.ResultsOf 1878 HCM patients studied (mean age 53±15 years; 41.6% female), only 71 (3.8%) had RV-Abn (24 RVE, 28 RVD, 19 combined RVE and RVD). Compared with HCM patients with RV-Norm, RV-Abn patients were older (57±14 vs 53±15 years, P=.02), more symptomatic (New York Heart Association functional class III-IV in 62.0% vs 48.6%, P=.03), had more atrial fibrillation (53.5% vs 17.3%, P<.001), and more prior implantable cardioverter-defibrillator implantation (23.9% vs 11.3%, P=.02). Median follow-up was 9.4 years with 311 deaths. Patients who were RV-Abn had higher all-cause mortality compared with RV-Norm (log-rank P<.001); 24.1% (95% CI, 15.5% to 35.3%) vs 6.1% (95% CI, 5.1% to 7.3%) at 5 years. In multivariable Cox modeling, RV-Abn (hazard ratio, 1.89; 95% CI, 1.18 to 3.03; P=.008) was associated independently with all-cause mortality after adjusting for age, female sex, New York Heart Association functional class, atrial fibrillation, hypertension, coronary artery disease, implantable cardioverter-defibrillator implantation, beta blocker use, prior septal reduction therapy, resting LV outflow tract gradient, maximal LV wall thickness, and moderate or greater tricuspid regurgitation.ConclusionAlthough perturbations in RV size and function were observed in fewer than 5% of patients with HCM, they were associated with nearly two-fold higher all-cause mortality at long-term follow-up.     

Clinical Outcomes of Adults With Bicuspid Aortic Valve: A European Perspective

ObjectiveTo describe the clinical history of patients with a wide age range diagnosed with bicuspid aortic valve (BAV) and no surgical indication and to evaluate the long-term outcome of patients with BAV referred for elective surgery.Patients and MethodsBetween 2005 and 2017, 350 consecutive patients with no surgical indication (surveillance group, mean age 53±16, 71% men) and 191 with a surgical indication (surgical group, mean age 59±13, 71% men) were prospectively included. Median follow-up was 80 (32 to 115) months.ResultsIn the surveillance group, the 5-year and 10-year survival rates were 93±1% and 89±2%, respectively, with a relative survival of patients with BAV compared with an age- and sex-matched control population of 98.7%. During follow-up, the cumulative 10-year incidence of aortic valve and aorta surgery was high; of 35±4%, the incidence of native valve infective endocarditis (IE) of 0.2% per patient-year, and no cases of aortic dissection were observed. In the surgical group, the 5-year and 10-year survival rates were 97±1% and 89±3%, respectively, with a relative survival of 99.4% compared with the general population. The incidence of IE was 0.4% per patient-year, and no cases of aortic dissection were observed.ConclusionThis regional cohort shows that the 10-year survival rates of patients with BAV and a wide age range, but mostly middle-aged adults, were similar to those of the general population with a very low rate of complications. Adherence to prophylactic surgical indications and younger age might have contributed to this lack of difference.     

Human Immunodeficiency Virus Infection and Variation in Heart Failure Risk by Age,Sex, and Ethnicity: The HIV HEART Study

ObjectivesTo evaluate the risk of heart failure (HF) linked to human immunodeficiency virus (HIV) infection, how risk varies by demographic characteristics, and whether it is explained by atherosclerotic disease or risk factor treatment.Patients and MethodsWe performed a retrospective cohort study of persons with HIV (PWHs) from January 1, 2000, through December 31, 2016, frequency-matched 1:10 to persons without HIV on year of entry, age, sex, race/ethnicity, and treating facility. We evaluated the risk of incident HF associated with HIV infection, overall and by left ventricular systolic function, and whether HF risk varied by demographic characteristics.ResultsAmong 38,868 PWHs and 386,586 matched persons without HIV, mean ± SD age was 41.4±10.8 years, with 12.3% female, 21.1% Black, 20.5% Hispanic, and 3.9% Asian/Pacific Islander. During median follow-up of 3.8 years (interquartile range, 1.4-9.0 years), the rate (per 100 person-years) of incident HF was 0.23 in PWHs vs 0.15 in those without HIV (P<.001). The PWHs had a higher adjusted HF rate (adjusted hazard ratio [aHR], 1.73; 95% confidence interval [CI], 1.57 to 1.91), which was only modestly attenuated after accounting for interim acute coronary syndrome events. Results were similar by systolic function category. The adjusted risk of HF in PWHs was more prominent for those 40 years and younger (aHR, 2.45; 95% CI, 1.92 to 3.03), women (aHR, 2.48; 95% CI, 1.90 to 3.26), and Asian/Pacific Islanders (aHR, 2.46; 95% CI, 1.27 to 4.74).ConclusionHIV infection increases the risk of HF, which varied by demographic characteristics and was not primarily mediated through atherosclerotic disease pathways or differential use of cardiopreventive medications.     

Noninvasive Voice Biomarker Is Associated With Incident Coronary Artery Disease Events at Follow-up

ObjectiveTo evaluate the association between a preidentified voice biomarker and incident coronary artery disease (CAD) events.MethodsPatients referred for clinically indicated coronary angiography underwent a total of three 30-second voice recordings using the Vocalis Health smartphone application between January 1, 2015, and February 28, 2017. A pre-established voice biomarker was derived from each individual recording, and the mean biomarker value was calculated for each patient. Individuals were clinically observed through December 31, 2019. The prespecified primary outcome was a composite of presenting to the emergency department with chest pain, being admitted to the hospital with chest pain, or having an acute coronary syndrome; the prespecified secondary outcome was a composite of a positive stress test result at follow-up or the presence of CAD at follow-up coronary angiography.ResultsIn the final analysis, 108 patients were included (mean age, 59.47±11.44 years; male, 59 [54.6%]). The median follow-up time was 24 months (range, 1 to 60 months). In multivariable Cox proportional hazards models adjusting for CAD grade on baseline angiography, a high baseline mean voice biomarker was significantly associated with both the primary (hazard ratio, 2.61; 95% CI, 1.42 to 4.80; P=.002) and secondary (hazard ratio, 3.13; 95% CI, 1.13 to 8.68; P=.03) composite outcomes.ConclusionThis study found a significant association between a noninvasive voice biomarker and incident CAD events at follow-up. These results may have important clinical implications for the remote and noninvasive screening of patients to identify those at risk of coronary disease and its complications.     

Clinical Presentation,Management, and Outcomes of Cardiovascular Implantable Electronic Device Infections Due to Gram-Negative Versus Gram-Positive Bacteria

ObjectiveTo describe and compare the clinical presentation, management, and outcomes of cardiovascular implantable electronic device (CIED) infections due to gram-negative bacteria (GNB) and CIED infections due to gram-positive bacteria (GPB).Patients and MethodsWe retrospectively reviewed all CIED infection cases at Mayo Clinic from January 1, 1992, through December 31, 2015. Cases were classified based on positive microbiology data from extracted devices or blood cultures.ResultsOf the 623 CIED infections during the study period, 31 (5.0%) were caused by GNB and 323 (51.8%) by GPB. Patients in the GNB group were more likely to present with local inflammatory findings at the pocket site (90.3% vs 72.4%; P=.03). All patients with bacteremia due to GNB had concomitant pocket infection compared with those with GPB (100% vs 33.9%; P=.002). After extraction, 41.9% of patients in the GNB group were managed with oral antibiotics vs 2.4% in the GPB group (P<.001). There were no statistically significant differences in infection relapse/recurrence or 1-year survival rates between the 2 groups.ConclusionCompared with CIED infections caused by GPB, those due to GNB are more likely to present with pocket infection. Device-related GNB bacteremia almost always originates from the generator pocket. After extraction, oral antibiotic drug therapy may be a reasonable option in select cases of pocket infections due to GNB. No difference in outcomes was observed between the 2 groups.     

The Lifestyle-Related Cardiovascular Risk Is Modified by Sleep Patterns

ObjectiveTo prospectively assess whether sleep patterns modified lifestyle-associated cardiovascular disease (CVD) risk.Patients and MethodsThis study included 393,690 participants without CVD at baseline measurements between March 13, 2006, and October 1, 2010, from UK Biobank. A lifestyle score was calculated on the basis of the 4 lifestyle factors (smoking, alcohol consumption, physical activity, and diet), and sleep patterns were constructed based on sleep duration, chronotype, insomnia, snoring, and daytime dozing.ResultsDuring a median follow-up of 8.93 years, we observed 10,218 incident CVD events, including 6595 myocardial infarctions (MIs) and 3906 strokes. We found that sleep patterns significantly modified the relations of the lifestyle score with incident CVD (P for interaction =.007) and MI (P for interaction =.004). Among participants with a poor sleep pattern, unfavorable lifestyle (per score increase) was associated with 25% (95% CI, 13% to 39%) and 29% (95% CI, 13% to 47%) increased risks for CVD and MI, while among participants with a healthy sleep pattern, unfavorable lifestyle was associated with 18% (95% CI, 15% to 21%) and 17% (95% CI, 13% to 21%) increased risks for CVD and MI.ConclusionOur results indicate that adherence to a healthy sleep pattern may attenuate the CVD risk associated with an unfavorable lifestyle.     

Effect of Omega-3 Dosage on Cardiovascular Outcomes: An Updated Meta-Analysis and Meta-Regression of Interventional Trials

ObjectivesTo quantify the effect of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids on cardiovascular disease (CVD) prevention and the effect of dosage.MethodsThis study is designed as a random effects meta-analysis and meta-regression of randomized control trials with EPA/DHA supplementation. This is an update and expanded analysis of a previously published meta-analysis which covers all randomized control trials with EPA/DHA interventions and cardiovascular outcomes published before August 2019. The outcomes included are myocardial infarction (MI), coronary heart disease (CHD) events, CVD events (a composite of MI, angina, stroke, heart failure, peripheral arterial disease, sudden death, and non-scheduled cardiovascular surgical interventions), CHD mortality and fatal MI. The strength of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework.ResultsA total of 40 studies with a combined 135,267 participants were included. Supplementation was associated with reduced risk of MI (relative risk [RR], 0.87; 95% CI, 0.80 to 0.96), high certainty number needed to treat (NNT) of 272; CHD events (RR, 0.90; 95% CI, 0.84 to 0.97), high certainty NNT of 192; fatal MI (RR, 0.65; 95% CI, 0.46 to 0.91]), moderate certainty NNT = 128; and CHD mortality (RR, 0.91; 95% CI, 0.85 to 0.98), low certainty NNT = 431, but not CVD events (RR, 0.95; 95% CI, 0.90 to 1.00). The effect is dose dependent for CVD events and MI.ConclusionCardiovascular disease remains the leading cause of death worldwide. Supplementation with EPA and DHA is an effective lifestyle strategy for CVD prevention, and the protective effect probably increases with dosage.     

High Prevalence of Celiac Disease Among Screened First-Degree Relatives

ObjectiveTo investigate the prevalence of first-degree relatives (FDRs) with celiac disease detected at screening and diagnostic significance of anti-tissue transglutaminase (anti-TTG).Patients and MethodsWe performed a retrospective cohort study of 104 patients with a diagnosis of celiac disease and their FDRs, collecting data from electronic records of Mayo Clinic and celiac disease registry from December 20, 1983, to May 22, 2017. We collected demographics, presenting symptoms, indication for testing, family history, number of other family members screened, biopsy reports, and results of serologic tests.ResultsOf 477 FDRs identified, 360 were screened (mean screening rate per family, 79%±25%) and 160 FDRs (44.4%) were diagnosed with celiac disease, at a mean age 31.9±21.6 years (62% female). All diagnosed FDRs had positive anti-TTG titers. Clinical features were documented in 148 diagnosed FDRs, of those 9 (6%) had classic, 97 (66%) had non-classic symptoms, and 42(28%) had no reported symptoms. Histology reports were available from 155 FDRs: 12 (8%) had Marsh 1, 77 (50%) had Marsh 3a, and 66 (43%) had Marsh 3b. A level of anti-TTG greater than or equal to 2.75 of the upper limit of normal identified FDRs with villous atrophy with 87% sensitivity, 82% specificity, and a positive predictive value of 95%.ConclusionIn a retrospective cohort study of patients diagnosed with celiac disease, we found a high prevalence of celiac disease among screened FDRs. High anti-TTG titers associated with villous atrophy on small bowel biopsies, irrespective of symptoms.     

Longitudinal Anthropometric Measures and Risk of New-Onset Atrial Fibrillation Among Community-Dwelling Men and Women

ObjectiveTo assess the sex-specific evolution of various anthropometric measures and the association of their longitudinal trajectories with new-onset atrial fibrillation (AF).MethodsAmong 5266 men and 7218 women free of AF at baseline from the prospective population-based Rotterdam Study, each anthropometric measure was measured 1 to 5 times from 1989 to 2014. Anthropometric measures were standardized to obtain hazard ratios per 1 SD increase to enable comparison. Joint models were used to assess the longitudinal association between anthropometric measures and incident AF. Use of the joint models is a preferred method for simultaneous analyses of repeated measurements and survival data for conferring less biased estimates.ResultsMean (SD) age was 63.9 (8.9) years for men and 64.9 (9.8) years for women. Median follow-up time was 10.5 years. Longitudinal evolution of weight, height, waist circumference, hip circumference, and body mass index was associated with an increased risk of new-onset AF in both men and women. In joint models, larger height in men (hazard ratio [95% credible interval] per 1 SD, 1.27 [1.17 to 1.38]) and weight in women (1.24 [1.16 to 1.34]) showed the largest associations with AF. In joint models, waist to hip ratio was significantly associated with incident AF only in women (1.10 [1.03 to 1.18]).ConclusionConsidering the entire longitudinal trajectories in joint models, anthropometric measures were positively associated with an increased risk for new-onset AF among men and women in the general population. Increase in measure of central obesity showed a stronger association with increased risk of AF onset among women compared with men.     

Renal Neoplasia in Tuberous Sclerosis: A Study of 41 Patients

ObjectiveTo study the clinical features and identify unique renal neoplasia subtypes and their prognostic implications in individuals with tuberous sclerosis complex (TSC).Patients and MethodsThe Mayo Clinic nephrectomy registry included 37 patients with TSC diagnosed between 1970 and 2018. Four additional patients were identified from the pathology consultation and autopsy files. All available renal tumors were further characterized using immunohistochemistry and fluorescence in situ hybridization. Clinicopathologic features and follow-up were obtained from the medical record. The American Association for Cancer Research Project GENIE registry was accessed using cBioPortal for molecular profiling of angiomyolipoma (AML).ResultsA total of 276 renal tumors from 41 patients were analyzed. Renal tumors were classified into 9 distinct morphological subtypes, with AML predominating (238 [86%]). Interestingly, all these tumors acted in a benign fashion except one renal cell carcinoma with clear cells and fibromyomatous stroma and one epithelioid AML that metastasized. Molecular profiling studies revealed that epithelioid AMLs were enriched for alterations of TP53, RB1, and ATRX. Eight patients died of direct complications of TSC, including 3 of end-stage renal disease. To date, none have died of a renal epithelial neoplasm.ConclusionThe identification of unique renal neoplasia subtypes may provide important clues to establish a diagnosis of TSC, and in the somatic setting, this finding has important implications for accurate prognostication. These tumors tend to be indolent, and only 2 of 276 tumors in our study exhibited metastatic behavior. Our results support multidisciplinary management with a focus on preservation of renal function.     

Outcomes of COVID-19 With the Mayo Clinic Model of Care and Research

ObjectiveTo report the Mayo Clinic experience with coronavirus disease 2019 (COVID-19) related to patient outcomes.MethodsWe conducted a retrospective chart review of patients with COVID-19 diagnosed between March 1, 2020, and July 31, 2020, at any of the Mayo Clinic sites. We abstracted pertinent comorbid conditions such as age, sex, body mass index, Charlson Comorbidity Index variables, and treatments received. Factors associated with hospitalization and mortality were assessed in univariate and multivariate models.ResultsA total of 7891 patients with confirmed COVID-19 infection with research authorization on file received care across the Mayo Clinic sites during the study period. Of these, 7217 patients were adults 18 years or older who were analyzed further. A total of 897 (11.4%) patients required hospitalization, and 354 (4.9%) received care in the intensive care unit (ICU). All hospitalized patients were reviewed by a COVID-19 Treatment Review Panel, and 77.5% (695 of 897) of inpatients received a COVID-19–directed therapy. Overall mortality was 1.2% (94 of 7891), with 7.1% (64 of 897) mortality in hospitalized patients and 11.3% (40 of 354) in patients requiring ICU care.ConclusionMayo Clinic outcomes of patients with COVID-19 infection in the ICU, hospital, and community compare favorably with those reported nationally. This likely reflects the impact of interprofessional multidisciplinary team evaluation, effective leveraging of clinical trials and available treatments, deployment of remote monitoring tools, and maintenance of adequate operating capacity to not require surge adjustments. These best practices can help guide other health care systems with the continuing response to the COVID-19 pandemic.     

Outcomes Following Percutaneous Coronary Intervention in Renal Transplant Recipients: A Binational Collaborative Analysis

ObjectiveTo investigate the clinical and procedural characteristics in patients with a history of renal transplant (RT) and compare the outcomes with patients without RT in 2 national cohorts of patients undergoing percutaneous coronary intervention (PCI).Patients and MethodsData from the National Inpatient Sample (NIS) and British Cardiovascular Intervention Society (BCIS) were used to compare the clinical and procedural characteristics and outcomes of patients undergoing PCI who had RT with those who did not have RT. The primary outcome of interest was in-hospital mortality.ResultsOf the PCI procedures performed in 2004-2014 (NIS) and 2007-2014 (BCIS), 12,529 of 6,601,526 (0.2%) and 1521 of 512,356 (0.3%), respectively, were undertaken in patients with a history of RT. Patients with RT were younger and had a higher prevalence of congestive cardiac failure, hypertension, and diabetes but similar use of drug-eluting stents, intracoronary imaging, and pressure wire studies compared with patients who did not have RT. In the adjusted analysis, patients with RT had increased odds of in-hospital mortality (NIS: odds ratio [OR], 1.90; 95% CI, 1.41-2.57; BCIS: OR, 1.60; 95% CI, 1.05-2.46) compared with patients who did not have RT but no difference in vascular or bleeding events. Meta-analysis of the 2 data sets suggested an increase in in-hospital mortality (OR, 1.79; 95% CI, 1.40-2.29) but no difference in vascular (OR, 1.24; 95% CI, 0.77-2.00) or bleeding (OR, 1.21; 95% CI, 0.86-1.68) events.ConclusionThis large collaborative analysis of 2 national databases revealed that patients with RT undergoing PCI are younger, have more comorbidities, and have increased mortality risk compared with the general population undergoing PCI.     

Prognostic Value of Cardiac Magnetic Resonance Imaging in Acute Coronary Syndrome Patients With Troponin Elevation and Nonobstructive Coronary Arteries

ObjectiveTo define the diagnostic yield of cardiac magnetic resonance (CMR) in differentiating the underlying causes of myocardial infarction with nonobstructive coronary arteries (MINOCA) and to determine the long-term prognostic implications of such diagnoses.MethodsCardiac magnetic resonance evaluation was performed in 227 patients (mean age, 56.4±14.9 years; 120 [53%] female) with a “working diagnosis” of MINOCA as defined by presentation with a troponin-positive acute coronary syndrome (troponin I >0.04 μg/L) and nonobstructed coronary arteries between January 1, 2007, and February 28, 2013. Follow-up was performed to assess the primary composite end point of myocardial infarction, heart failure, and all-cause mortality.ResultsCardiac magnetic resonance identified nonstructural cardiomyopathies in 97 (43%) patients, myocardial infarction in 55 (24%) patients, structural cardiomyopathies in 27 (12%) patients, and pulmonary embolism in 1 patient. No CMR abnormalities were identified in the remaining patients. Kaplan-Meier analysis demonstrated the ability of a CMR diagnosis to predict the risk of the primary composite end point (P=.005) at 5-year follow-up. Worse outcomes were seen among patients with “true” MINOCA and a normal CMR image compared with those with CMR-confirmed myocardial infarction (P=.02). Use of antiplatelets (78% [37/45] vs 95% [52/55]; P=.01), beta blockers (56% [25/45] vs 82% [45/55]; P=.004), and statins (64% [29/45] vs 85% [47/55]; P=.01) was significantly lower in patients with true MINOCA with normal CMR imaging compared with those with CMR-confirmed myocardial infarction.ConclusionsCardiac magnetic resonance carries a high diagnostic yield in patients with MINOCA and predicts long-term prognosis. Patients with MINOCA with normal CMR imaging had an increased rate of major adverse cardiac events and lower use of guideline-recommended myocardial infarction therapy compared with those with CMR-confirmed myocardial infarction.     

Physical Activity,Inflammation, Coronary Artery Calcification,and Incident Coronary Heart Disease in African Americans: Insights From the Jackson Heart Study

ObjectiveTo examine associations between physical activity (PA), inflammation, coronary artery calcification (CAC), and incident coronary heart disease (CHD) in African Americans.MethodsAmong Jackson Heart Study participants without prevalent CHD at baseline (n=4295), we examined the relationships between PA and high-sensitivity C-reactive protein, the presence of CAC (Agatston score ≥100), and incident CHD. Based on the American Heart Association’s Life’s Simple 7 metrics, participants were classified as having poor, intermediate, or ideal PA.ResultsAfter adjustment for possible confounding factors, ideal PA was associated with lower high-sensitivity C-reactive protein levels (β, ?0.15; 95% CI, ?0.15 to ?0.002) and a lower prevalence of CAC (odds ratio, 0.70; 95% CI, 0.51-0.96) compared with poor PA. During a median of 12.8 years of follow-up, there were 164 incident CHD events (3.3/1000 person-years). Ideal PA was associated with a lower rate of incident CHD compared with poor PA (hazard ratio, 0.55; 95% CI, 0.31-0.98).ConclusionIn a large community-based African American cohort, ideal PA was associated with lower inflammation levels, a lower prevalence of CAC, and a lower rate of incident CHD. These findings suggest that promotion of ideal PA may be an important way to reduce the risk of subclinical and future clinical CHD in African Americans.     

Changing trends in the incidence and spectrum of cancers between 1990 and 2021 among HIV-infected patients in Busan,Korea

BackgroundLong-term follow-up data on cancer incidence and spectrum among human immunodeficiency virus (HIV)-infected individuals in Korea have been scarce.Material and MethodsThis retrospective cohort study included HIV-infected individuals visiting a tertiary care hospital in Busan, South Korea between 1990 and 2021. The observation was divided into 4 periods. The incidence rate was calculated using direct standardization on age and sex, stratified by calendar period.ResultsOf the 1,297 patients, 92 patients (7.1%) were diagnosed with 97 cancers. Excluding 37 patients with prevalent cancer, 1,260 patients were followed for a total of 8,803.7 person-years (PYs), and 55 patients developed 60 incident cancers including 5 second primary incident cancers. In men, the AIDS-defining cancer (ADC) incidence decreased from 294.7 per 100,000 PYs in 1990–1997 to 124.8 per 100,000 PYs in 2014–2021, while the non-AIDS-defining cancer (NADC) incidence increased from 0 per 100,000 PYs to 316.5 per 100,000 PYs during the same period. The proportion of virus-unrelated NADCs (VU-NADCs) increased from 33.3% in 1998–2005 to 49% in 2014–2021. The proportion of human papillomavirus-associated cancers (HPVACs) has recently increased in both ADCs and NADCs. The median time from HIV diagnosis to their first cancer was 1.48 years for ADCs, 6.11 years for VR-NADCs, 8.3 years for VU-NADCs, and 11.5 years for HPVACs.ConclusionThe incidence of NADCs is increasing with the aging of HIV-infected patients, and thus, it is necessary to promote cancer screening and prevention programs.     

Colleagues Meeting to Promote and Sustain Satisfaction (COMPASS) Groups for Physician Well-Being: A Randomized Clinical Trial

ObjectiveTo evaluate physician small groups to promote physician well-being in a scenario with provided discussion topics but without trained facilitators, and for which protected time was not provided but meal expenses were compensated.Participants and MethodsWe conducted a randomized controlled trial of 125 practicing physicians in the Department of Medicine, Mayo Clinic, Rochester, Minnesota, between October 2013 and October 2014 with subsequent assessment of organizational program implementation. Twelve biweekly self-facilitated discussion groups involving reflection, shared experience, and small-group learning took place over 6 months. Main outcome measures included meaning in work, burnout, symptoms of depression, quality of life, social support, and job satisfaction assessed using validated metrics.ResultsAt 6 months after completion of the intervention (12 months from baseline), the rate of overall burnout had decreased by 12.7% (31/62 to 19/51) in the intervention arm versus a 1.9% increase (25/61 to 24/56) in the control arm (P<.001). The rate of depressive symptoms had decreased by 12.8% (29/62 to 17/50) in the intervention arm versus a 1.1% increase (20/61 to 19/56) in the control arm (P<.001). The proportion of physicians endorsing at least moderate self-reported likelihood of leaving their current practice in the subsequent 2 years had decreased by 1.9% (17/62 to 13/51) in the intervention arm and increased by 6.1% (14/61 to 16/55) in the control arm (P<.001). No statistically significant differences were seen in mean changes in burnout scale scores, meaning, or social support, although numeric differences generally favored the intervention.ConclusionSelf-facilitated physician small-group meetings improved burnout, depressive symptoms, and job satisfaction. This intervention represents a low-cost strategy to promote important dimensions of physician well-being.Trial Registrationclinicaltrials.gov Identifier: NCT04466423
