Beta-Blockers for Acute Myocardial Infarction - Essay Example
The researcher of this essay aims to analyze the usefulness of beta-blockers, that is a short form of “beta-adrenergic receptor blocking agents” for acute myocardial infarction. This essay presents several studies and researchers, that were consucted on the topic…
This essay states that in the list of leading causes of U.S. deaths, heart disease ranks first and stroke ranks third. The British Heart Foundation states that myocardial infarction, also known as heart attack or coronary thrombosis, is a disease wherein the heart suddenly loses its blood supply. If not treated immediately, it can lead to the death of the affected area and consequently, the cessation of all heart functions. Most MIs happen to people over 50 and the incidence is higher in men than in women. Several treatments are available including aspirin and other platelet drugs, emergency angioplasty, heparin, and beta-blocker drugs. The term “beta-blocker” is a short form of “beta-adrenergic receptor blocking agents”. When used to treat acute myocardial infarction, it reduces oxygen supply, which is beneficial since this decreases myocardial workload and oxygen demand. Once a person has undergone an MI, beta-blocker is required for life. The results of the study showed that there was no significant difference in the incidence of MI between atenolol, placebo and other hypertensives. While the risk of stroke was 19% lower in the beta-blocker group, there were no differences noted for MI or all-cause mortality. Recent clinical trials suggest that beta-blockers are linked with increased risk of type-2 diabetes. However, beta-blockers are still valuable for heart rate control in patients with tachyarrhythmias and that the studies that contradict the effectiveness of beta-blockers do not apply to new ones.
