The COVID-19 pandemic required a significant redeployment of worldwide healthcare resources. Fear infection, national lockdowns and altered priorities have the potential to impact utilisation resources for non-communicable diseases. To survey health professionals' views on rate timing admission patients with ST-elevation myocardial infarction (STEMI), European Society Cardiology (ESC) administered an internet-based questionnaire cardiologists cardiovascular nurses across 6 continents. 3101...

Temporal changes in systemic arterial compliance and wave propagation properties (pulsatile load) their role ventricular-systemic coupling during gestation have not been explored. Noninvasive methods combined with recently developed mathematical modeling techniques were used to characterize vascular left ventricular (LV) mechanical adaptations normal gestation.Fourteen healthy women studied at each trimester of pregnancy again postpartum. Experimental measurements included instantaneous...

Long QT syndrome (LQTS) is a heritable disease associated with ECG interval prolongation, ventricular tachycardia, and sudden cardiac death in young patients. Among genotyped individuals, mutations genes encoding repolarizing K+ channels (LQT1:KCNQ1; LQT2:KCNH2) are present approximately 90% of affected individuals. Expression pore mutants the human KCNQ1 (KvLQT1-Y315S) KCNH2 (HERG-G628S) rabbit heart produced transgenic rabbits long phenotype. Prolongations intervals action potential...

Background and Purpose- Left atrial enlargement has been shown to be associated with ischemic stroke, but the association embolic stroke mechanisms remains unknown. We aim study associations between left volume index (LAVI) subtypes fibrillation (AF) detection on cardiac event monitoring in patients of unknown source. Methods- Data were collected from a prospective cohort consecutive admitted comprehensive center over 18 months. Stroke subtype was classified into cardioembolic...

Background and Purpose— The presence of white matter hyperintensities on brain MRI is common among elderly individuals. Previous research suggests that cardiovascular risk factors are associated with increased hyperintensities. Examining the role direct physiological measures vascular function will help to clarify mechanisms related aim present study was examine association between endothelial-dependent endothelial-independent vasodilatation hyperintensity volume. Methods— Twenty-five older...

Several trials support the usefulness of disease management (DM) for improving clinical outcomes in heart failure (HF). Most these studies are limited by small sample size; absence concurrent, randomized controls; follow-up; restriction to urban academic centers; and low baseline use effective medications.We performed a prospective, assessment effectiveness HF DM delivered 90 days across diverse provider network heterogeneous population 200 patients with high approved pharmacotherapy. During...

This study examines the relationship between systemic vascular function, neurocognitive performance, and structural brain abnormalities on magnetic resonance imaging (MRI) among geriatric outpatients with treated, stable cardiovascular disease no history of neurological illness (n = 88, ages 56–85 years). Vascular function was assessed by cardiac ejection fraction output, sequential systolic diastolic blood pressures, flow mediated brachial artery reactivity (BAR), carotid intima media...
