RESUMO
Heart failure, a growing concern in the United States, significantly impacts both morbidity and mortality. Classified by ejection fraction, heart failure with preserved ejection fraction (HFpEF) now accounts for half of all cases and is steadily rising. Unlike its counterpart, heart failure with reduced ejection fraction (HFrEF), HFpEF lacks clear management guidelines. Recognizing this critical gap, we aim to review existing recommendations and formulate effective management strategies for HFpEF.
RESUMO
The association between untreated obstructive sleep apnea (OSA) and cardiovascular disease (CVD) is well known. In this literature review, we aim to review the existing literature on treatment effects of OSA and its impact on CVD morbidity and mortality, stratified by gender. We systematically reviewed PubMed, Medline, and Scopus per PRISMA guidelines and included 25 studies in the final review. Primary outcomes were CVD-associated morbidity and mortality. Out of 25 studies, 10 were meta-analysis, 8 observational, and 7 randomized controlled trials. The treatment modality was continuous positive airway pressure (CPAP) in 23 studies, noninvasive positive pressure ventilation, and oral appliance therapy in 2. Secondary prevention of CVD was the endpoint in 23 studies. A total of 165,775 participants between 45 and 75 years of age, 60%-90% males, and the average Epworth Sleepiness Scale (ESS) score was 5-9. CV outcomes included myocardial infarction, angina, heart failure (HF), acute coronary syndrome (ACS), coronary artery disease (CAD), ischemic heart disease, cardiomyopathy, atrial fibrillation (AF), and hypertension. In 4 studies, CPAP was associated with a reduction in CVD mortality, and 10 studies showed improvement in morbidity. Our review of literature did not show consistent benefits in CV outcomes in OSA patients. We identified many potential research areas, especially the lack of studies demonstrating dose-dependent effect of OSA treatment on CV outcomes, especially when stratified by severity of OSA and gender. Larger prospective studies with longer follow-up will be helpful to study these parameters.

Lyme's carditis and neuroborreliosis are common manifestation of disseminated Lyme disease. However, third-degree atrioventricular blocks with Lyme's carditis requiring permanent pacemaker with neuroborreliosis and Lyme's disease-associated immunodeficiency are uncommon. Here we present a case of 64-year-old female presenting with neurological symptoms and electrocardiogram changes suggestive of complete heart block with no improvement in the degree of heart block with intravenous antibiotics, requiring permanent pacemaker implantation and course complicated by fungemia.

Contemporary literature reveals a range of cardiac complications in patients who receive the percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). This study compared the adverse cardiac outcomes and procedural/technical success rates between the patients groups of in-stent (IS) CTO PCI and de novo CTO PCI. This systematic review and meta-analysis compared odds for primary (all-cause mortality, MACE, cardiac death post PCI, stroke) and secondary (bleeding requiring blood transfusion, ischemia-driven target-vessel revascularization, PCI procedural success, PCI technical success, and target-vessel MI) endpoints between 2734 patients who received PCI for IS CTO and 17,808 for de novo CTO. Odds ratios for outcome variables were calculated within 95% confidence intervals (CIs) via the Mantel-Haenszel method. The pooled analysis was undertaken for observational (retrospective/prospective) single- and multicentered studies published between January 2005 and December 2021. We found 57% higher, 166% higher, 129% higher, and 57% lower odds for MACE (OR: 1.57, 95% CI 1.31, 1.89, P < 0.001), ischemia-driven target-vessel revascularization (OR: 2.66, 95% CI 2.01, 3.53, P < 0.001), target-vessel myocardial infarction (MI) (OR: 2.29, 95% CI 1.70, 3.10, P < 0.001), and bleeding requiring blood transfusion (OR: 0.43, 95% CI 0.19, 1.00, Pâ¯=â¯0.05), respectively, in patients with IS CTO PCI as compared to that of the de novo CTO PCI. No statistically significant differences between the study groups were recorded for the other primary/secondary outcome variables. The findings from this study indicated a high predisposition for MACE, ischemia-driven target-vessel revascularization, target vessel MI, and a lower incidence of bleeding episodes among IS CTO PCI patients as compared to those with de novo CTO PCI. The prognostic outcomes in CTO PCI cases require further investigation with randomized controlled trials.

Heart Failure (HF) and Opioid Use Disorder (OUD) independently have significant impact on patients and the United States (US) health system. In the setting of the opioid epidemic, research on the effects of OUD on cardiovascular diseases is rapidly evolving. However, no study exists on differential outcomes of ischemic cardiomyopathy (ICM) and nonischemic cardiomyopathy (NICM) in patients with HF with OUD. We performed a retrospective, observational cohort study using National Inpatient Sample (NIS) 2018-2020 databases. Patients aged 18 years and above with diagnoses of HF with concomitant OUD were included. Patients were further classified into ICM and NICM. Primary outcome of interest was differences in all- cause in-hospital mortality. Secondary outcome was incidence of cardiogenic shock. We identified 99,810 hospitalizations that met inclusion criteria, ICM accounted for 27%. Mean age for ICM was higher compared to NICM (63 years vs 56 years, P < 0.01). Compared to NICM, patients with ICM had higher cardiovascular disease risk factors and comorbidities; type 2 diabetes mellitus (46.3 % vs 30.1%, P < 0.01), atrial fibrillation/flutter (33.5% vs 29.9%, P < 0.01), hyperlipidemia (52.5% vs 28.9%, P < 0.01), and Charlson comorbidity index ≥5 was 46.7% versus 29.7%, P < 0.01. After controlling for covariates and potential confounders, we observed higher odds of all-cause in-hospital mortality in patients with NICM (aORâ¯=â¯1.36; 95% CI:1.03-1.78, Pâ¯=â¯0.02). There was no statistical significant difference in incidence of cardiogenic shock between ICM and NICM (aORâ¯=â¯0.86;95% CI 0.70-1.07, Pâ¯=â¯0.18). In patients with HF with concomitant OUD, we found a 36% increase in odds of all-cause in-hospital mortality in patients with NICM compared to ICM despite being younger in age with less comorbidities. There was no difference in odds of in-hospital cardiogenic shock in this study population. This study contributes to the discussion of OUD and cardiovascular diseases which is rapidly developing and requires further prospective studies.

Study objective: To assess temporal changes in clinical profile and in-hospital outcome of patients with amyloidosis presenting with non-ST elevation myocardial infarction, NSTEMI. Design/setting: We conducted a retrospective observational study using the National Inpatient Sample (NIS) database from January 1, 2010, to December 31, 2020. Main outcomes: Primary outcome of interest was trend in adjusted in-hospital mortality in patients with amyloidosis presenting with NSTEMI from 2010 to 2020. Our secondary outcomes were trend in rate of coronary revascularization, and trend in duration of hospitalization. Results: We identified 272,896 hospitalizations for amyloidosis. There was a temporal increase in incidence of NSTEMI among patients aged 18-44 years from 15.5 % to 28.0 %, a reverse trend was observed in 45-64 years: 22.1 % to 17.7 %, p = 0.043. There was no statistically significant difference in rate of coronary revascularization from 2010 to 2020; 16.3 % to 14.2 %, p = 0.86. We observed an increased odds of all-cause in-hospital mortality in patients with NSTEMI compared to those without NSTEMI (aOR = 2.2, 95 % CI: 1.9-2.6, p < 0.001) but there was a decrease trend in mortality from 21.5 % to 11.3 %, p = 0.013 for trend. Hospitalization duration was also observed to decreased from 14.1 days to 10.9 days during the study period (p = 0.055 for trend). Conclusion: In patients with amyloidosis presenting with NSTEMI, there was increased incidence of NSTEMI among young adults, a steady trend in coronary revascularization, and a decreasing trend of adjusted all-cause in-hospital mortality and length of hospitalization from 2010 to 2020 in the United States.
RESUMO
Background: Orthostatic hypotension and atrial fibrillation have common etiology and a bidirectional relationship with several cardiovascular conditions. Despite both conditions being highly prevalent in hospitalized patients, prior research has primarily evaluated adverse outcomes due to orthostatic hypotension and atrial fibrillation independent of each other. In this study, we aim to assess if the presence of atrial fibrillation exacerbates in-hospital outcomes of patients with orthostatic hypotension. Methods: Adult patients hospitalized in 2019 with a primary diagnosis of orthostatic hypotension with or without pre-existing atrial fibrillation were identified using the International Classification of Diseases, Tenth Revision (ICD-10) code. The primary outcome of interest was in-patient mortality and cardiac arrest. Secondary outcomes of interest were the length of stay and total hospital charges. Adjusted and unadjusted analysis was performed on appropriate variables of interest. Results: Among 10,630 hospitalizations with orthostatic hypotension, 2,987 (median (interquartile range (IQR)) age: 78.5 (68.5 - 88.5) years; 1,197 women (40.1%)) comprised the atrial fibrillation cohort. Mean Charlson comorbidity index was noted to be significantly higher in orthostatic hypotension and atrial fibrillation patients (mean (standard deviation (SD)): 3.1 (2.1) vs. 2.5 (2.1), P < 0.001).Compared to orthostatic hypotension patients without atrial fibrillation, the prevalence of congestive heart failure (1,263 (42.3%) vs. 1,367 (17.9%)), coronary artery disease (1,432 (47.9%) vs. 2,481 (32.5%)), history of percutaneous coronary intervention or graft (443 (14.83%) vs. 860 (11.3%)), chronic obstructive pulmonary disease (644 (21.6%) vs. 1,131 (14.8%)) , chronic kidney disease (1,182 (39.6%) vs. 2,216 (29.0%)), and hyperlipidemia (1,828 (61.2%) vs. 4,087 (53.5%); all P < 0.05), were significantly higher in orthostatic hypotension patients with atrial fibrillation. Following multivariable analysis of orthostatic hypotension patients, atrial fibrillation was associated with 5.0 times greater odds for cardiac arrest (adjusted odds ratio (aOR) = 5.0 (95% confidence interval (CI): 1.4 - 18.2), P = 0.014), without increased risk of in-hospital mortality (aOR = 2.1 (95% CI: 0.9 - 5.0), P = 0.090). Conclusions: Atrial fibrillation is an independent predictor for cardiac arrest but not in-hospital mortality in patients with orthostatic hypotension. The short- and long-term prognostic value of atrial fibrillation in orthostatic hypotension patients must be confirmed in future prospective trials to improve patient outcomes.
RESUMO
BACKGROUND: The goal of the present study was to determine the prevalence of left ventricular systolic dysfunction (LVSD) and associated clinical correlates in African Americans (AA) diagnosed with ischemic stroke (IS). METHODS: Retrospective chart analysis was done on all diagnosed AA IS patients between January 2010 and March 2012. Patients with atrial fibrillation were excluded. A total of 147 patients were included in the study. Transthoracic 2-dimensional echocardiography was used to assess left ventricular systolic function, and study groups were categorized as normal, mild, moderate, and severely abnormal, based on the ejection fraction (EF). Available imaging studies were analyzed for data collection. Logistic regression and Pearson chi-square tests were performed. RESULTS: Normal EF was present in 114 of 147 patients (78%). Mild abnormality was present in 9 of 147 (6%), moderate in 8 of 147 (5%), and severe in 16 of 147 (11%) patients. In patients with mildly reduced EF, smoking was the most common (RF). In patients with moderately and severely reduced EFs, hypertension was the most common RF. History of smoking was commonly found in systolic dysfunction group compared with normal group (P = .001). Logistic regression analysis revealed that smoking and advanced age were the significant predictors for LVSD. Large-vessel IS were more common in systolic dysfunction group than normal EF group (P = .017). CONCLUSIONS: Prevalence of LVSD in AA with IS was 22% in our study. Smoking was a significant modifiable RF associated with systolic dysfunction. A history of smoking and higher age could predict the occurrence of LVSD. There were more large-vessel IS in patients with LVSD.
