Recent studies are leading to a critical reevaluation of the long-standing use of beta blockers in heart attack treatment. Research suggests that these commonly prescribed medications may not be effective for all patients, with evidence indicating that women might experience worse outcomes, including a potentially increased risk of death. While beta blockers have been the standard treatment after a heart attack, new findings highlight inconsistencies in their benefits, particularly for women, prompting doctors to reconsider their routine use in post-myocardial infarction care.
