“In a new study from Kaiser Permanente, researchers found the use of aromatase inhibitors, hormone-therapy drugs used to treat patients with breast cancer, was not associated with an increased risk of fatal cardiovascular events, including heart attacks or stroke, compared with tamoxifen, another commonly prescribed anti-cancer drug that works on hormones and which has been associated with a serious risk of stroke.
“While women taking aromatose inhibitors did not have an increased risk of death from heart attacks or stroke, the study, published today in JAMA Oncology, found that those who only used aromatase inhibitors or used the drugs after tamoxifen treatment had a 26 to 29 percent higher risk of less serious cardiovascular events, such as abnormal heart beat and pericarditis (a swelling and irritation of the thin membrane surrounding the heart), compared with those who only used tamoxifen.”
