In order to assess left ventricular structure and diastolic function, 50 hypertensive male subjects, 25 with and 25 without a history of alcohol abuse, and 20 normotensive male controls underwent Doppler echocardiographic examination followed by ambulatory blood pressure monitoring for 24 hours. Left ventricular mass was significantly higher in alcoholic hypertensives in relation to non-alcoholic hypertensives (p < 0.05) and normotensive controls (p < 0.001). Moreover, Doppler parameters expressing left ventricular filling pattern were significantly worse in alcoholic than in non-alcoholic hypertensives (p < 0.01). Clinic and ambulatory blood pressure were similar in alcoholic and non-alcoholic hypertensives, while mean day-time heart rate was significantly higher in alcoholics (p < 0.01). Collected data suggest that non-hemodynamic factors are probably involved in the development of cardiovascular abnormalities in hypertensive alcoholics, and that echocardiography should be employed for risk-profile definition in alcohol-associated hypertension.

Approximately 1% of all live births in the USA are affected by congenital heart disease (CHD), the leading cause of congenital defect-related illness and infant death. Although technological innovations have improved CHD diagnosis in utero, variation among fetal cardiac counseling practices persists. Our study aims to evaluate physician counseling content based on cardiac defect complexity.

Aims: Dapagliflozin (DAPA), a sodium-glucose co-transporter 2 inhibitor, has been shown to reduce cardiovascular mortality among patients with chronic heart failure. We aimed to evaluate the impact on a worsening renal function (WRF) by adding DAPA as compared to standard decongestive therapy with loop diuretics alone.
Methods And Results: We enrolled 114 consecutive acute decompensated heart failure (ADHF) patients with a left ventricular ejection fraction (LVEF) of less than 50%.
Aims: Large-scale, real-world data on early initiation of sacubitril/valsartan in patients newly diagnosed (de novo) with HF with reduced ejection fraction (HFrEF) are limited. We examined the effectiveness of sacubitril/valsartan versus angiotensin-converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB) on all-cause and cause-specific hospitalizations among patients with de novo HFrEF from the Optum® dataset in the United States.
Methods: This retrospective cohort study included adult patients with de novo HFrEF (diagnosed ≤30 days) with left ventricular ejection fraction (LVEF) ≤40% who were first prescribed with sacubitril/valsartan or ACEi/ARB from 1 January 2016 to 31 March 2020.

This study investigated how contraction frequency impacts the mechano-energetics of cardiac muscle performing mechanical work. Left-ventricular trabeculae were isolated from rat hearts and mounted in our work-loop calorimeter to assess their function at physiological temperature (37°C) across three stimulation frequencies, 2 Hz, 3.5 Hz and 5 Hz, in a randomised sequence.

Background: Discrete prepotentials (DPPs) mapped inside aortic sinuses of Valsalva (ASVs) are deemed as reliable targets for ablation of premature ventricular contractions (PVCs). Nevertheless, ablation may still fail, necessitating further investigation. This study aimed to investigate the electrophysiological features and ablation approaches for PVCs with failed ablation inside ASVs, despite identified DPPs.
