A new study from the University of Bologna has uncovered an important difference in how women and men respond to certain blood pressure medications.
The research, published in the journal Hypertension, found that women who take beta-blockers for high blood pressure—without any history of heart disease—may have a higher risk of developing heart failure than men when they experience serious heart problems.
Beta-blockers are widely used drugs that help lower blood pressure and reduce the risk of heart-related conditions. High blood pressure, or hypertension, is one of the leading causes of heart attacks and strokes.
Doctors often prescribe beta-blockers to prevent these problems. But this new research shows that the same treatment might not work the same way for everyone.
The study looked at health data from 13,764 adults across 12 countries in Europe. All participants had high blood pressure but no previous signs of cardiovascular disease. The researchers divided them into groups by gender and whether they were using beta-blockers.
They found a concerning trend. Women who were taking beta-blockers had a 4.6% higher chance of developing heart failure after being hospitalized for a heart event called acute coronary syndrome. This condition happens when blood flow to the heart is suddenly blocked or reduced.
The risk was even greater for women who had a specific and severe type of heart attack known as STEMI (ST-segment elevation myocardial infarction). These women were 6.1% more likely to develop heart failure than men with the same condition.
Interestingly, men and women who were not taking beta-blockers had nearly the same rate of heart failure. This suggests that the medication itself might be causing the increased risk in women.
Heart failure is a serious condition. Among patients who developed heart failure after a heart attack, the chance of dying was seven times higher than for those who had a heart attack without heart failure.
The study did not explore the exact reasons behind these gender differences, but it offered some ideas. One possibility is that hormone replacement therapy (HRT), often used by some women during or after menopause, may interact with beta-blockers. However, this needs more research.
Another possibility is that women and men may process medications differently, which could affect how well the drugs work—or what side effects they cause.
This research points to the need for personalized treatment plans, especially for women with high blood pressure. Doctors may need to think twice before prescribing beta-blockers to women who do not already have heart disease. Instead, women might benefit from focusing more on non-drug approaches like healthy eating, exercise, and stress reduction.
The findings also highlight a bigger issue in healthcare: many treatments are based on studies mostly done with men. But men and women can respond differently to the same medication. Understanding these differences is key to improving care for everyone.
If you are a woman with high blood pressure, it may be a good idea to talk with your doctor about this new research. Together, you can decide on the best treatment for your unique health needs.
