A new study suggests that taking beta blockers for a long time after having a heart attack may not be necessary for patients who do not have heart failure.
Beta-blockers are drugs that can help manage heart conditions such as abnormal heart rhythms, angina, and high blood pressure.
They are commonly prescribed after a heart attack to help lower the risk of another heart attack or other heart problems.
However, it was not clear if these drugs were necessary for patients who did not have heart failure or another complication known as left ventricular systolic dysfunction (LVSD) beyond the first year.
The study, which was published in the journal Heart, looked at data from 43,618 adults who had a heart attack between 2005 and 2016.
None of these patients had heart failure or LVSD, and the researchers wanted to find out if there were any differences in deaths or rates of further heart problems between those who were taking beta blockers more than a year after their heart attack and those who weren’t on these drugs.
The study found that long-term treatment with beta-blockers did not seem to be associated with improved cardiovascular outcomes during an average monitoring period of 4.5 years.
The researchers found no difference in the risk of death or further heart problems between patients who were taking beta blockers and those who weren’t.
The study was observational, which means that it can’t establish a cause-and-effect relationship. And while it was the largest study of its kind to date, it had some limitations.
For example, patients weren’t randomly assigned to treatment, and there was no indication of how consistently patients took their drugs. Also, the study did not include information on patients’ quality of life.
The researchers suggest that it may be time to reassess the value of long-term treatment with beta-blockers in heart attack patients who don’t have heart failure or LVSD.
Beta-blockers are associated with several side effects such as depression and fatigue, and the study suggests that they may not be necessary for all heart attack patients.
In a related editorial, the authors note that while there is strong evidence that beta blockers can improve outcomes after a heart attack, it is not clear if this benefit applies to lower-risk patients who are taking other evidence-based therapies and who have a normal functioning heart.
They suggest that more evidence from large randomized clinical trials is needed to answer this question.
Overall, the study suggests that taking beta blockers for a long time after a heart attack may not be necessary for all patients and that further research is needed to determine which patients may benefit most from these drugs.
Patients who have questions about their medications should talk to their healthcare provider.
