Long-term use of high blood pressure beta blocker may not prevent a second heart attack

After experiencing a heart attack, many patients are prescribed beta blockers to reduce the risk of further heart problems.

These drugs help manage various heart conditions, such as irregular heart rhythms, angina, and high blood pressure.

However, a recent study suggests that prolonged use of beta blockers might not be necessary for heart attack survivors who don’t have heart failure or a specific heart issue called left ventricular systolic dysfunction (LVSD) beyond the first year.

Let’s delve into the study’s findings and what it means for patients.

The study, published in the journal Heart, examined data from 43,618 adults who suffered a heart attack between 2005 and 2016.

Importantly, none of these patients had heart failure or LVSD.

The primary goal was to determine whether there were any differences in death rates or the occurrence of additional heart problems between those who continued taking beta blockers for more than a year after their heart attack and those who didn’t.


Surprisingly, the study found that extended beta blocker treatment did not appear to lead to improved cardiovascular outcomes during an average monitoring period of 4.5 years.

In simple terms, patients who took beta blockers for an extended period did not fare any better than those who didn’t in terms of survival and avoiding further heart problems.

It’s essential to note that this study was observational, which means it can’t prove a direct cause-and-effect relationship. Additionally, there were certain limitations.

Patients were not randomly assigned to receive treatment, and it wasn’t clear how consistently patients took their prescribed medications. Moreover, the study did not assess the patients’ quality of life.

What Does It Mean for Patients?

Based on the study’s findings, it may be time to reconsider the necessity of long-term beta blocker treatment for heart attack survivors without heart failure or LVSD.

Beta blockers can have side effects, including depression and fatigue, which can impact a patient’s overall well-being. This research suggests that not all heart attack survivors require beta blockers.

The Need for Further Research

In an accompanying editorial, the authors highlighted that while beta blockers have proven benefits after a heart attack, it remains uncertain whether these benefits extend to lower-risk patients who are already receiving other evidence-based therapies and have a normally functioning heart.

To address this uncertainty, additional large-scale randomized clinical trials are needed to provide clearer answers.


In summary, the recent study questions the necessity of prolonged beta blocker use for heart attack survivors without heart failure or LVSD.

While beta blockers have been shown to be effective for certain patients, they may not be equally beneficial for all.

Patients who are concerned about their medication regimen should engage in a conversation with their healthcare provider to explore the best treatment options tailored to their specific needs and circumstances.

It’s crucial to stay informed about heart health developments, and this study adds to the ongoing research in the field.

As always, individuals should consult with their healthcare providers to make informed decisions regarding their heart health and medication choices.
