Discontinuing beta-blockers after heart attack found to be safe for low-risk patients

Among stable, relatively low-risk patients who had previously suffered a heart attack, discontinuing beta-blockers after at least one year was found to be non-inferior, or comparable, to continuing beta-blockers in terms of death, another heart attack or hospitalization for heart failure, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Next-generation oral SERD therapy lowers the risk of breast cancer recurrence

In an international study led by UCLA, researchers have shown that giredestrant, a next-generation oral selective estrogen receptor antagonist and degrader (SERD), when given as an adjuvant therapy for early-stage (1-3) hormone receptor (HR)-positive, HER2-negative breast cancer, significantly lowered the risk of the disease returning when compared with standard hormone therapies long considered the backbone of treatment.
