Effect of beta-blockers on arrhythmias during six weeks after suspected myocardial infarction

Effect of beta-blockers on arrhythmias during six weeks after suspected myocardial infarction.

Twenty-four-hour electrocardiographic tape-recording was used to investigate the incidence of arrhythmias in patients with suspected myocardial infarction who were receiving either propranolol, atenolol, or placebo. Recordings begun within 24 hours after admission to a coronary care unit showed that 76% of patients eventually found to have had a myocardial infarction had ventricular arrhythmias...

Beta-Blockers and Depression After Myocardial Infarction

OBJECTIVES The purpose of this research was to explore the prospective relationship between the use of beta-blockers and depression in myocardial infarction (MI) patients. BACKGROUND Beta-blocker use has been reported to be associated with the development of depression, but the methodological quality of studies in this field is weak. METHODS In a multicenter study, MI patients (n 127 non–beta-b...

Why do beta-receptor blockers decrease mortality after myocardial infarction?

Beta Blockers in Cardioprotection after Acute Myocardial Infarction

In post myocardial infarction patients beta blockers have shown a reduction of total mortality (23%), sudden cardiac death (25%) and non fatal reinfarction (30%). Beside beta blockers, only a few agents have shown reduction of mortality and sudden cardiac death in post myocardial infarction patients. Beta blockers have showed more favorable effects In patients with Q wave myocardial infarction ...

Beta blockers after myocardial infarction: have trials changed practice?

A survey of British consultant cardiologists was carried out to elicit their current practices when prescribing long term beta blockers after myocardial infarction. Sixty (72%) of the respondents reported that they used beta blockers prophylactically even in the absence of any other indications; the details of their stated policies, however, varied considerably. The favourable evidence of clini...
