A large new study suggests that women with high blood pressure may not always respond to blood pressure medicine in the same way as men.
Researchers found that women taking beta-blockers, a widely used group of medicines for high blood pressure, had a higher risk of developing heart failure after certain serious heart events. The findings could help doctors make more personalized treatment decisions in the future.
The research was carried out by scientists at the University of Bologna and was published in the journal Hypertension.
High blood pressure, also called hypertension, is one of the most common health problems around the world. Many people have no symptoms, but over time it can damage blood vessels, the heart, the brain, and the kidneys. If left untreated, it greatly increases the risk of heart attack, stroke, heart failure, and other serious diseases.
Doctors often prescribe beta-blockers to help lower blood pressure and reduce the workload on the heart. These medicines slow the heart rate and make it easier for the heart to pump blood.
They have been used safely for many years and remain an important treatment for many patients. However, scientists continue to study whether different groups of people benefit from them in the same way.
In this study, researchers wanted to know whether men and women with high blood pressure, but no previous history of heart disease, experienced different outcomes while taking beta-blockers. They were especially interested in what happened after acute coronary syndromes.
These are medical emergencies that happen when blood flow to the heart suddenly drops. They include heart attacks and other dangerous conditions that need immediate treatment.
The researchers analyzed medical information from 13,764 adults living in 12 European countries. All participants had high blood pressure but had never been diagnosed with heart disease before joining the study. The scientists compared men and women who were taking beta-blockers with those who were not.
The results showed an important difference. Women taking beta-blockers were about 4.6% more likely than men to be hospitalized with heart failure after an acute coronary syndrome. Heart failure does not mean the heart has stopped working.
Instead, it means the heart can no longer pump blood around the body as well as it should. This can cause tiredness, shortness of breath, and swelling in the legs and feet.
The study also found that people who developed heart failure had a much poorer outlook. Their risk of dying was about seven times higher than that of people who experienced a heart attack without developing heart failure.
The difference between men and women became even larger in patients with ST-segment elevation myocardial infarction, usually called STEMI.
This is one of the most severe types of heart attack because a major heart artery becomes completely blocked. Women with STEMI who were taking beta-blockers 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 developed heart failure at similar rates. This suggests that the difference may be linked to how women respond to the medication under certain conditions, although more research is needed before firm conclusions can be made.
The researchers also noted that using beta-blockers together with hormone replacement therapy might further increase the risk of heart failure in some women. However, this was not the main focus of the study, so additional research will be needed to better understand this possible connection.
The findings do not mean that women should stop taking beta-blockers on their own. These medicines remain highly effective and lifesaving for many people.
Instead, the study highlights the importance of regular medical check-ups and personalized treatment plans. Doctors can consider a patient’s age, overall health, medical history, and other medicines when choosing the best treatment.
The researchers also emphasized that healthy lifestyle habits remain one of the best ways to control high blood pressure. Eating a balanced diet, staying physically active, maintaining a healthy weight, avoiding smoking, limiting alcohol, and following medical advice can all reduce the risk of heart disease.
As scientists learn more about how men and women respond differently to medicines, future treatments may become more personalized. This could improve safety and help ensure every patient receives the treatment that works best for them.
