Abstract

Adrenergic β‑blockers are drugs that bind to, but do not activate β‑adrenergic receptors. Instead they block the actions of β-adrenergic agonists and are used for the treatment of various diseases such as cardiac arrhythmias, angina pectoris, myocardial infarction, hypertension, headache, migraines, stress, anxiety, prostate cancer, and heart failure. Several meta‑analysis studies have shown that β‑blockers improve the heart function and reduce the risks of cardiovascular events, rate of mortality, and sudden death through chronic heart failure (CHF) of patients. The present study identified results from recent meta‑analyses of β‑adrenergic blockers and their usefulness in CHF. Databases including Medline/Embase/Cochrane Central Register of Controlled Trials (CENTRAL), and PubMed were searched for the periods May, 1985 to March, 2011 and June, 2013 to August, 2015, and a number of studies identified. Results of those studies showed that use of β‑blockers was associated with decreased sudden cardiac death in patients with heart failure. However, contradictory results have also been reported. The present meta‑analysis aimed to determine the efficacy of β‑blockers on mortality and morbidity in patients with heart failure. The results showed that mortality was significantly reduced by β‑blocker treatment prior to the surgery of heart failure patients. The results from the meta‑analysis studies showed that β‑blocker treatment in heart failure patients correlated with a significant decrease in long‑term mortality, even in patients that meet one or more exclusion criteria of the MERIT‑HF study. In summary, the findings of the current meta-analysis revealed beneficial effects different β‑blockers have on patients with heart failure or related heart disease.
