Blood Pressure Drugs and Heart-Failure Risk: What the Research Actually Says
This headline appears to refer to research on beta-blockers. An important distinction is that the research did not show that beta-blockers generally cause heart failure in women.
A 2020 study examined 13,764 patients hospitalized with acute coronary syndrome. Among people who had hypertension but no previous cardiovascular disease, women who had been taking beta-blockers before hospitalization had a higher rate of heart failure at presentation than men taking beta-blockers: 21.3% versus 16.7%. The researchers reported an association between prior beta-blocker use and this sex difference, but the study does not establish that beta-blockers directly caused the heart failure.

Don’t stop the medication on your own. Beta-blockers are important treatments for several cardiovascular conditions.
-
The risk-benefit calculation depends on why the drug was prescribed, the specific beta-blocker, dose, other illnesses, and other medications.
-
Current hypertension guidance does not recommend a different general blood-pressure treatment strategy simply because someone is a woman. JACC
-
In some people who already have heart failure, particular beta-blockers are actually part of standard treatment. JACC
Bottom line: The evidence supports paying attention to possible sex-related differences in how cardiovascular drugs affect patients, but it does not justify telling women to avoid beta-blockers or implying that these medicines routinely cause heart failure.
If you tell me the name of the blood-pressure medication you’re asking about, I can explain its known heart-failure risks and benefits.
