It is known that certain cardiovascular diseases (CVD) are associated, like atrial fibrillation and stroke. However, for other CVDs, the links and temporal trends are less studied. In this longitudinal study, we have investigated temporal epidemiological and genetic associations between different CVDs.

KCNMA1 encodes the α-subunit of the large-conductance Ca2+-activated K+ channel, KCa1.1, and lies within a linkage interval for atrial fibrillation (AF). Insights into the cardiac functions of KCa1.1 are limited, and KCNMA1 has not been investigated as an AF candidate gene.

Coronary artery disease (CAD) is a multifactorial condition with both genetic and exogenous causes. The contribution of tissue-specific functional networks to the development of atherosclerosis remains largely unclear. The aim of this study was to identify and characterize central regulators and networks leading to atherosclerosis.

Randomized clinical trials indicate that the immune response plays a significant role in coronary artery disease (CAD), a disorder impacting the lifespan potential. However, the identification of targets critical to the immune response in atheroma is still hampered by a lack of solid inference.

Background Global budget payments (GBP) are considered effective in containing health care expenditures; however, information on their impact on quality of cardiovascular care is limited. We aimed to evaluate the effects of GBP on utilization, outcomes, and costs for 3 major cardiovascular conditions. Methods We analyzed claims data of hospital admissions in Maryland from fiscal year 2013 to 2018. Using segmented regression, we evaluated temporal trends in hospitalizations, length of stay, percutaneous coronary intervention and coronary artery bypass grafting volumes, case mix-adjusted 30-day readmission rates, risk-standardized mortality rates, and hospitalization charges in patients with principal diagnosis of heart failure, acute ischemic stroke, and acute myocardial infarction (AMI) in relation to GBP implementation. Trends in global cardiovascular procedure charges/volumes were also studied. Results Hospitalization rates for congestive heart failure and AMI remained unaffected by GBP, while the gradient of ischemic stroke admissions decreased (Ptrend <0.0001). Length of stay slightly increased for patients with congestive heart failure (Ptrend=0.03). Inpatient coronary artery bypass grafting surgeries decreased (Ptrend <0.0001). We observed a significant decrease in casemix-adjusted 30-day readmission rate in the AMI cohort beyond the prepolicy trend (Ptrend=0.0069). There were no significant changes in mortality for any of the 3 conditions. Hospitalization charges increased for ischemic stroke (Ptrend <0.0001), remained constant for congestive heart failure (Ptrend=0.1), and decreased for AMI (Ptrend=0.0005). We observed a significant increase in electrocardiography rate charges (Ptrend <0.0001), coincidentally with a reduction in volumes (Ptrend=0.0003). Conclusions Introducing GBP in Maryland had no perceivable adverse effects on inpatient outcomes and quality indicators for 3 major cardiovascular conditions. Savings were observed in the AMI cohort, possibly due to reduced unnecessary readmissions, efficiency improvements, or shifts to outpatient care. Reduced cardiovascular procedure volumes were counterbalanced by a proportional rise in charges. State-level adoption of GBP with pay-for-performance incentives may be effective for cost containment without adversely impacting quality of cardiovascular care.

Stroke remains a devastating complication of transcatheter aortic valve replacement (TAVR), which has persisted despite refinements in technique and increased operator experience. While cerebral embolic protection devices (EPDs) have been developed to mitigate this risk, data regarding their impact on stroke and other outcomes after TAVR are limited.

Dilated cardiomyopathy (DCM) is a leading cause of death in children with heart failure. The outcome of pediatric heart failure treatment is inconsistent, and large cohort studies are lacking. Progress may be achieved through personalized therapy that takes age- and disease-related pathophysiology, pathology, and molecular fingerprints into account. We present single nuclei RNA sequencing from pediatric patients with DCM as the next step in identifying cellular signatures.

More than 40 years after the 1978 Bethesda Conference on the Declining Mortality from Coronary Heart Disease provided the scientific community with a blueprint for systematic analysis to understand declining rates of coronary heart disease, there are indications the decline has ended or even reversed despite advances in our knowledge about the condition and treatment. Recent data show a more complex situation, with mortality rates for overall cardiovascular disease, including coronary heart disease and stroke, decelerating, whereas those for heart failure are increasing. To mark the 40th anniversary of the Bethesda Conference, the National Heart, Lung, and Blood Institute and the American Heart Association cosponsored the "Bending the Curve in Cardiovascular Disease Mortality: Bethesda + 40" symposium. The objective was to examine the immediate and long-term outcomes of the 1978 conference and understand the current environment. Symposium themes included trends and future projections in cardiovascular disease (in the United States and internationally), the evolving obesity and diabetes epidemics, and harnessing emerging and innovative opportunities to preserve and promote cardiovascular health and prevent cardiovascular disease. In addition, participant-led discussion explored the challenges and barriers in promoting cardiovascular health across the lifespan and established a potential framework for observational research and interventions that would begin in early childhood (or ideally in utero). This report summarizes the relevant research, policy, and practice opportunities discussed at the symposium.
