A new study from the University of Bologna has raised concerns about the safety of beta-blockers, especially for women with high blood pressure but no history of heart disease.
These drugs are often prescribed to manage hypertension, a common condition that increases the risk of heart problems.
However, the research shows that the effects of beta-blockers may differ between men and women, with women facing a higher chance of serious complications.
The study looked at data from nearly 14,000 adults in 12 European countries. All participants had high blood pressure but had never been diagnosed with cardiovascular disease. The researchers grouped them by gender and whether or not they were taking beta-blockers.
They then followed their health outcomes, focusing on what happened when these individuals were hospitalized for a serious heart condition known as acute coronary syndrome—a situation where the heart’s blood supply is suddenly blocked.
The results were troubling. Women who were taking beta-blockers were nearly 5% more likely to develop heart failure than men in the same situation.
When both men and women developed heart failure, their risk of death was about seven times higher than for those who had a heart attack without heart failure. Women with a severe type of heart attack called STEMI, where a coronary artery is fully blocked, had a 6.1% higher risk of heart failure than men with the same condition.
Interestingly, the risk of heart failure was about the same for men and women who were not on beta-blockers. This suggests that the medication itself might be contributing to the gender gap in outcomes.
This study underlines the importance of considering gender differences in medical treatments. Most medications are tested in ways that may not fully capture how they affect women and men differently.
The findings also highlight the need for lifestyle-based approaches—like healthy eating and regular exercise—as important ways to manage high blood pressure, especially for women who haven’t had heart problems before.
The researchers also pointed out a possible connection between hormone replacement therapy (HRT) and the increased heart failure risk in women taking beta-blockers. While this link hasn’t been confirmed, it may be an important area for future research.
The main message of the study is clear: we need more personalized medical care that takes gender into account. For women with high blood pressure, regular checkups and careful medication reviews may help reduce the risk of serious heart conditions.
Doctors should think twice before using a one-size-fits-all approach, especially when prescribing medications like beta-blockers.
Published in the journal Hypertension, this study by Professor Raffaele Bugiardini and his team adds valuable knowledge to how men and women respond differently to common heart medications. It strengthens the call for personalized healthcare that is based on detailed research and real-world outcomes.
