Chest Pain in Women: Gender- and Sex-based Differences in the Presentation and Diagnosis of Heart Disease.

Ischemic heart disease is a major cause of morbidity and mortality in the US, affecting both men and women significantly. The presentation of chest pain is largely similar in female and male patients, but additional non-chest pain symptoms can confound timely diagnosis in women. Management, diagnostic evaluation, and clinical outcomes for patients admitted with chest pain differ significantly between men and women, and understanding of these discrepancies is limited.

Optimizing the Approach and Clinical Outcomes of Women Undergoing Chronic Total Occlusion-Percutaneous Coronary Intervention.

Coronary artery disease remains a leading cause of morbidity and mortality globally, with chronic total occlusions (CTOs) representing a particularly challenging subset. Percutaneous coronary intervention (PCI) for CTOs has evolved significantly over the years, driven by advancements in equipment, techniques, and operator expertise. However, women have historically been underrepresented in clinical trials and guidelines, leading to a gap in an evidence-based management tailored to their specific needs, including in CTO-PCI.

Percutaneous Coronary Intervention Versus Robotic Coronary Bypass for Left Anterior Descending Artery Chronic Total Occlusion.

Background: Both percutaneous coronary interventions (PCIs) and robotic-assisted coronary artery bypass (CAB) offer viable options for left anterior descending (LAD) chronic total occlusion (CTO) revascularization. Our study aims to compare long-term clinical outcomes associated with these 2 strategies.

Methods: In this retrospective study, we analyzed data from 273 patients diagnosed with LAD CTO who underwent either PCI (n = 129) or CAB (n = 144) at a single institution.

A systematic review of present and future pharmaco-structural therapies for hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is a common contemporary, treatable, genetic disorder that can be compatible with normal longevity. While current medical therapies are ubiquitous, they are limited by a lack of solid evidence, are often inadequate, poorly tolerated, and do not alter the natural disease course. As such, there has long been a need for effective, evidence-based, and targeted disease-modifying therapies for HCM.

Transient left bundle branch block associated with very high coronary artery calcium: a case report.

Coronary artery calcium (CAC) is the measure of subclinical coronary artery atherosclerosis most strongly associated with atherosclerotic cardiovascular disease (ASCVD) risk. However, CAC is rarely reported in the inpatient setting to guide chest pain management. We present a case of very high CAC in a 64-year-old woman with hypertension, type 2 diabetes, and hyperlipidemia presenting with dyspnea.

Intestinal barrier dysfunction in murine sickle cell disease is associated with small intestine neutrophilic inflammation, oxidative stress, and dysbiosis.

The intestinal microbiome has emerged as a potential contributor to the severity of sickle cell disease (SCD). We sought to determine whether SCD mice exhibit intestinal barrier dysfunction, inflammation, and dysbiosis. Using the Townes humanized sickle cell mouse model, we found a 3-fold increase in intestinal permeability as assessed via FITC-dextran (4 kDa) assay in SS (SCD) mice compared to AA (wild type) mice ( = 4,  < 0.

Update on Minimalist TAVR Care Pathways: Approaches to Care in 2022.

Purpose Of Review: This review summarizes current data supporting a minimalist TAVR approach and identifies the need for additional study to optimize TAVR care. The authors discuss future directions of the TAVR landscape and how this necessitates evolution of minimalist care pathways.

Recent Findings: Transcatheter aortic valve replacement (TAVR) has become a mainstay in the treatment of aortic stenosis since the initial procedure in 2002.

Cardiac rehabilitation in women, challenges and opportunities.

Cardiac rehabilitation(CR) has known proven benefits in reducing mortality related to cardiovascular disease (CVD), improving quality of life (QoL), and preventing CVD-related readmissions. Despite these known benefits, CR remains underutilized among women relative to men. Disparities exist at the level of referral, enrollment, and program completion.

Relation of prior statin and anti-hypertensive use to severity of disease among patients hospitalized with COVID-19: Findings from the American Heart Association's COVID-19 Cardiovascular Disease Registry.

Background: Statins have anti-inflammatory and immunomodulatory effects that may reduce the severity of coronavirus disease 2019 (COVID-19), in which organ dysfunction is mediated by severe inflammation. Large studies with diverse populations evaluating statin use and outcomes in COVID-19 are lacking.

Methods And Results: We used data from 10,541 patients hospitalized with COVID-19 through September 2020 at 104 US hospitals enrolled in the American Heart Association's COVID-19 Cardiovascular Disease (CVD) Registry to evaluate the associations between statin use and outcomes.

Metabolic Scar Assessment withF-FDG PET: Correlation to Ischemic Ventricular Tachycardia Substrate and Successful Ablation Sites.

The functional and molecular imaging characteristics of ischemic ventricular tachycardia (VT) substrate are incompletely understood. Our objective was to compare regional F-FDG PET tracer uptake with detailed electroanatomic maps (EAMs) in a more extensive series of postinfarction VT patients to define the metabolic properties of VT substrate and successful ablation sites. Three-dimensional (3D) metabolic left ventricular reconstructions were created from perfusion-normalized F-FDG PET images in consecutive patients undergoing VT ablation.

Inflow Cannula Position Influences Improvement in Mitral Regurgitation After Ventricular Assist Device Implantation.

Significant residual mitral regurgitation (MR) after left ventricular assist device (LVAD) implantation has been associated with increased morbidity and mortality. The effect of cannula position on improvement of preexisting MR has yet to be evaluated. Consecutive patients who underwent centrifugal LVAD implantation with >mild preoperative MR and without concomitant mitral repair were reviewed.

Less Invasive Approach to Left Ventricular Assist Device Implantation May Improve Survival in High-Risk Patients.

Objective: Despite improvement in outcomes after left ventricular assist device (LVAD) implantation over the past 2 decades, high-risk recipients continue to have a prohibitive rate of morbidity and mortality. We hypothesized that a less invasive approach to LVAD implantation would be associated with improved survival compared to a conventional approach in this high-risk cohort.

Methods: All consecutive LVAD recipients (2013 to 2017) that underwent centrifugal LVAD implantation were retrospectively reviewed.

Vascular responses to coronary calcification following implantation of newer-generation drug-eluting stents in humans: impact on healing.

Aims: Vascular calcification is routinely encountered in percutaneous coronary intervention (PCI) and severe coronary calcification is a known predictor of in-stent restenosis and stent thrombosis. However, the histopathologic mechanisms behind such events have not been systematically described.

Methods And Results: From our registry of 1211 stents, a total of 134 newer-generation drug-eluting stents (DES) (Xience, Resolute-Integrity, PROMUS-Element, and Synergy) with duration of implant ≥30 days were histologically analysed.

Cardiac function assessed by myocardial deformation in adult polycystic kidney disease patients.

Background: Patients with autosomal dominant polycystic kidney disease (ADPKD) have an increased risk of cardiovascular morbidity and mortality. Impaired left ventricular (LV) global longitudinal strain (GLS) can be a sign of subclinical cardiac dysfunction even in patients with otherwise preserved ejection fraction (EF). Transmitral early filling velocity to early diastolic strain rate (E/SRe) is a novel measure of LV filling pressure, which is often affected early in cardiac disease.

Less invasive left ventricular assist device implantation may reduce right ventricular failure.

Objectives: Right ventricular (RV) failure after left ventricular assist device (LVAD) implantation continues to be a morbid complication. In this study, we hypothesized that a less invasive approach to implantation would preserve RV function relative to a conventional sternotomy (CS) approach.

Methods: All patients (2013-2017) who underwent LVAD implantation were reviewed.

CD163+ macrophages promote angiogenesis and vascular permeability accompanied by inflammation in atherosclerosis.

Intake of hemoglobin by the hemoglobin-haptoglobin receptor CD163 leads to a distinct alternative non-foam cell antiinflammatory macrophage phenotype that was previously considered atheroprotective. Here, we reveal an unexpected but important pathogenic role for these macrophages in atherosclerosis. Using human atherosclerotic samples, cultured cells, and a mouse model of advanced atherosclerosis, we investigated the role of intraplaque hemorrhage on macrophage function with respect to angiogenesis, vascular permeability, inflammation, and plaque progression.
