Sudden cardiac death (SCD) represents a major challenge in managing chronic heart failure (CHF). There is extensive evidence of the antifibrillatory action of beta-blockers and their ability to prevent SCD in patients with CHF and left ventricular (LV) dysfunction following myocardial infarction (...
Heart rate-lowering treatments (mainly beta-blockers) are usually recommended in case of acute myocarditis, especially in case of heart failure or arrhythmias, but level of proof remains weak. Calcium channel inhibitors and digoxin are sometimes proposed, albeit in limited situations. It is possible...
(fasting state, withholding beta-blockers and other cardiac medications, caffeine intake prior to pharmacological stress testing, infiltration of the intravenous line and contamination); (2) technical factors (motion and gating artifacts, inadequate quality control and machine calibration); (3) heart ...

Renal outcomes in high-risk hypertensive patients treated with an angiotensin-converting enzyme inhibitor or a calcium channel blocker vs a diuretic: a report from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). Arch Intern Med. 2005;165:936–46. Article ...
Results:A total of 425 patients were enrolled (65 卤 12 years of age, LVEF 32% [IQR: 25%-38%], 94% on beta blockers). Patients with decreased BRS (n=96 of 267, 36%) had lower exercise tolerance and heart rate variability (P< 0.05), whereas those with increased CRS to both ...
