A common drug used to treat heart attacks may not help and could have fatal consequences for women
A type of drug used to help treat heart attacks does not work on the majority of patients and may actually contribute to hospitalisation and death for women, new research has found.
Beta-blockers are medicines that are used to lower blood pressure and cause the heart to beat more slowly and with less force. They have been used as first-line treatment after heart attacks for decades, according to CNN.
However, a study published Saturday in the European Heart Journal found that women with little heart damage after suffering heart attacks who were treated with beta-blockers were significantly more likely to have another heart attack or be hospitalized for heart failure further down the line.
These women were also nearly three times more likely to die compared with women not given the drug, the study found. This was especially true for women receiving high doses of beta-blockers, according to lead study author Dr. Borja Ibanez.
Despite this, the same is not true for men, the research found.
Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver, told CNN that women being more susceptible to harm caused by beta-blockers than men was “actually not surprising.”
“Gender has a lot to do with how people respond to medication,” Freeman told the outlet.
“In many cases, women have smaller hearts. They’re more sensitive to blood pressure medications. Some of that may have to do with size, and some may have to do with other factors we have yet to fully understand.”
