Beta-Blocker Heart Attack Trial (BHAT) Clinical Trials Facts presented on Clinical Trials Search isn't designed to be a substitute for proven healthcare advice, calls or treatment using a real mD. We aren't mDs. Always confer with your physician on Beta-Blocker Heart Attack Trial (BHAT) conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Beta-Blocker Heart Attack Trial (BHAT) Clinical research trials and Beta-Blocker Heart Attack Trial (BHAT) healthcare trials happen in a lot of of localities across the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally measure the potency of new drugs. The aim of the studies / undertakings is to answer particular human medical questions. Clinical trials are a popular manner for doctors, government agencies, and private sector corporations to discover remedies for all kinds of circumstances, such as Beta-Blocker Heart Attack Trial (BHAT). Beta-Blocker Heart Attack Trial (BHAT) Clinical Trials and other clinical trials allow volunteers to get healthcare treatment alternatives before they are available to the general public. Most times the participants receive treatment for without cost, and occasionally they are paid for their time. Sometimes there is a cost for a Beta-Blocker Heart Attack Trial (BHAT) clinical trial. Human subjects often receive the most effective healthcare possible for their Beta-Blocker Heart Attack Trial (BHAT) condition. Risks are a reality, nonetheless, and may include more or frequent dr. calls, healthcare hazards (perhaps life-threatening), and/or the treatment being ineffective. Trials are federally governed with rigorous guidelines to protect clinical trials subjects.

Beta-Blocker Heart Attack Trial (BHAT)
For Condition: Arrhythmia,Cardiovascular Diseases,Coronary Disease,Death, Sudden, Cardiac,Heart Diseases,Myocardial Infarction,Myocardial Ischemia,Ventricular Fibrillation
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To determine whether the regular administration of the beta-blocker drug propranolol to people who had had at least one documented myocardial infarction would result in a significant reduction of mortality from all causes over the follow-up period. Eligible volunteer patients were recruited to participate in a double-blind clinical trial within 21 days after the onset of the acute event. One-half of the patients were randomly assigned to a beta-blocking drug (propranolol) and one-half to a placebo. The trial also evaluated the effect of propranolol on incidences of coronary heart disease mortality, sudden cardiac death, and nonfatal myocardial infarction plus coronary heart disease mortality in persons with documented previous myocardial infarction.
Details: BACKGROUND: Survivors of a documented myocardial infarction are recognized as having a high risk of dying relative to the general population. Serious arrhythmias, occurring with or without evidence of new infarction, are a common cause of death in this population. Theoretically, an agent which (1) can block the sympathetic nervous activity thought to be involved in precipitating sudden death and (2) has non-neurogenic antiarrhythmic properties would be of value to people with coronary heart disease. Propranolol, like other beta- blocking agents, has these as well as other properties and therefore might be expected to prevent or retard complications of coronary heart disease such as serious arrhythmias. This would be reflected in a decrease in mortality due to coronary heart disease. A workshop on chronic antiarrhythmic therapy reviewed contemporary experimental data and clinical practice and recommended that a clinical trial be undertaken to clearly show the effects of beta-blocking drugs on mortality. Subsequently, such a trial was approved by the Clinical Applications and Prevention Advisory Committee, by the Cardiology Advisory Committee, and by the National Heart, Lung, and Blood Advisory Council. The study protocol was reviewed in February 1978 and recommended for approval by the policy-data monitoring board and ad hoc members. The protocol was approved by the Director of NHLBI in March 1978. Recruitment started on June 19, 1978, and ended in October 1980. A total of 3,837 patients were randomized. Units which participated in the trial included 32 clinical centers, an EKG center, a central laboratory, a coordinating center, a 1-hour ambulatory ECG center, a 24-hour ambulatory EKG center, and an EKG tape quality control center. DESIGN NARRATIVE: A randomized, double-blind design with single experimental and control groups. Patients were recruited while in the hospital for an acute myocardial infarction and were enrolled in the study before discharge. Eligible patients fulfilled the study definition of an acute myocardial infarction. The diagnosis was based either on electrocardiographic records showing evolving QRS segment changes or on ST segment and T wave changes together with enzyme changes and appropriate clinical history. One-half of the patients were placed on therapy using a beta-blocking drug (propranolol). The other half received a placebo. The prescribed maintenance dosage of propranolol was either l80 or 240 mgs/day, depending upon serum drug levels. Intervention duration averaged 25 months.
