ABSTRACT
OBJECTIVE: People living with HIV have an increased risk of heart failure (HF). There are different subtypes of HF. Knowledge about the factors differentiating HF subtypes in people with HIV is limited but necessary to guide preventive measures and treatment. METHODS: A retrospective review of medical records was undertaken in people with HIV aged ≥18 years who received care at the University of Miami/Jackson Memorial HIV Clinic between January 2017 and November 2019 (N = 1166). Patients with an echocardiogram available for review (n = 305) were included. HF was defined as a documented diagnosis of any HF subtype (n = 52). We stratified those with HF by their ejection fraction (EF) into HF with preserved EF (HFpEF), HF with borderline EF, or HF with reduced EF (HFrEF). RESULTS: The prevalence of HF was 4.5%. The cohort included 46.2% females and 75% self-identified African Americans. Those with HF had a higher prevalence of hypertension, prior myocardial infarction, angina, coronary artery disease, percutaneous coronary intervention, coronary artery bypass grafting, diastolic dysfunction, and left ventricle hypertrophy. People with HIV with HF with borderline EF exhibited more coronary artery disease than those with HFpEF. CONCLUSIONS: We characterize HF in people with HIV in South Florida and report the prevalence of HF and HF subtypes. Only a small percentage of patients had echocardiograms performed, suggesting an ongoing need for recognition of the increased risk of HF in people living with HIV, and raising the concern about lack of awareness contributing to underdiagnosis and missed treatment opportunities in this population.
ABSTRACT
Septal Myectomy (SM) and Alcohol Septal Ablation (ASA) improve symptoms in patients with Hypertrophic Cardiomyopathy with outflow tract obstruction (oHCM). However, outcomes data in this population is predominantly from specialized centers. The National Inpatient Database was queried from 2011 to 2019 for relevant international classification of diseases (ICD)-9 and -10 diagnostic and procedural codes. We compared baseline characteristics and in-hospital outcomes of patients with oHCM who underwent SM vs ASA. A p-value < 0.001 was considered statistically significant. We identified 15,119 patients with oHCM who underwent septal reduction therapies, of whom 57.4% underwent SM, and 42.6% underwent ASA. Patients who underwent SM had higher all-cause mortality (OR: 1.8 (1.3-2.5)), post-procedure ischemic stroke (OR: 2.3 (1.7-3.2)), acute kidney injury (OR: 1.4 (1.2-1.7)), vascular complications (OR: 3.6 (2.3-5.3)), ventricular septal defect (OR: 4.4 (3.2-6.1)), cardiogenic shock (OR: 1.7 (1.3-2.3)), sepsis (OR: 3.2 (1.9-5.4)), and left bundle branch block (OR: 3.5 (3-4)), compared to ASA. Patients who underwent ASA had higher post-procedure complete heart block (OR: 1.3 (1.1-1.4)), right bundle branch block (OR: 6.3 (5-7.7)), ventricular tachycardia (OR: 2.2 (1.9-2.6)), supraventricular tachycardia (OR: 1.6 (1.4-2)), and more commonly required pacemaker insertion (OR: 1.4 (1.3-1.7)) (p < 0.001 for all) compared to SM. This nationwide analysis evidenced that patients undergoing SM had higher in-hospital mortality and periprocedural complications than ASA; however, those undergoing ASA had more post-procedure conduction abnormalities and pacemaker implantation. The implications of these findings warrant further investigation regarding patient selection strategies for these therapies.

Background: The impact of race and its related social determinants of health on cardiovascular disease outcomes has been well documented. However, limited data exist regarding the association of race with in-hospital outcomes in patients admitted for sinus node dysfunction (SND). Objective: To evaluate whether racial disparities exist in outcomes for patients hospitalized with a primary diagnosis of SND. Methods: The National Inpatient Sample was queried from 2011 to 2018 for relevant ICD-9 and ICD-10 diagnosis and procedure codes. Baseline characteristics and in-hospital outcomes in patients with a primary diagnosis of SND were compared among White and non-White patients. A multivariate logistic regression model was used to adjust for potential confounding factors and statistically significant comorbidities between both cohorts. Results: We identified 655,139 persons admitted with a primary diagnosis of SND, 520,926 (79.5%) of whom were White. Non-White patients had significantly higher all-cause mortality, length of stay, and total hospital cost. There were lower odds of pacemaker insertion (adjusted odds ratio [aOR] 1.13 [95% confidence interval (CI) 1.11-1.15]), temporary transvenous pacing (aOR 1.15 [95% CI 1.11-1.22]), and cardioversion (aOR 1.50 [95% CI 1.42-1.58]) in non-White patients. A subgroup analysis was performed and non-Hispanic Black race was predictive of a decreased odds of pacemaker insertion, cardioversion/defibrillation, and temporary transvenous pacing. Conclusion: Significant differences of in-hospital outcomes exist between White and non-White patients with SND. These findings appeared to be primarily driven by disparities in non-Hispanic Black patients. Increased recognition and focused efforts to mitigate these disparities will improve the care of underrepresented populations treated for SND.
