Beta Blockers, a Class of Drugs Used in Management abnormal heart rhythmangina pectoris and hypertension are routinely prescribed. history of heart attack To lower the risk of recurrence of the condition.
The study followed more than 40,000 heart attack patients and found that long-term treatment with beta-blockers was not associated with improved cardiovascular outcomes during an average monitoring period of 4.5 years.
The largest study to date Efficacy of β-blockersresearchers followed for a year 43,618 adults who had heart attacks requiring hospital care between 2005 and 2016 and whose details were registered in the Swedish national registry. coronary artery disease (Swedish Heart).
The results showed that people using beta-blockers did not have significantly better results than those who did not use the drugs.
Of all patients, 34,253 subjects were prescribed beta-blockers and remained on these drugs one year after discharge, while 9,365 were not prescribed these drugs.
“Approximately 6,475 (19%) of patients taking beta-blockers and those who did not, died of any cause, had another heart attack, required unplanned revascularization, or 2,028 (22%) of patients hospitalized for heart failure.
“After considering potentially influencing factors such as demographics and relevant coexistence conditions, there were no discernible differences in the incidence of these events between the two groups,” the study revealed. .
The researchers clarified that their study was observational and therefore unable to identify causation, the largest study of its kind to date, but the findings do not show certain limitations. should be viewed in the context of
This study further demonstrates the value of long-term treatment with these drugs in heart attack patients who do not have heart failure or LVSD (left ventricular systolic dysfunction), as beta blockers are associated with side effects such as depression and fatigue. increase. Needs re-evaluation.
