Patients who have had a myocardial infarction (MI) but do not have heart failure or left ventricular systolic dysfunction do not seem to benefit from beta blockers, a large UK study published in the Journal of the American College of Cardiology has found
Nearly 8% of middle aged and older people in the United States have myocardial scars suggestive of myocardial infarction, almost 80% of which have not been detected by electrocardiography or clinical evaluation, a study published in JAMA has found.
The researchers wrote, “The clinical significance of unrecognized myocardial scar remains to be defined, although prior myocardial scar has been noted pathologically in more than 70% of patients with sudden cardiac death but without prior known coronary artery disease.”
Hormone replacement therapy (HRT) offers women no protection against having or dying from a myocardial infarction while increasing the risk of blood clots and stroke, a new analysis published by the Cochrane Collaboration has shown.
But, complicating the message, a subgroup analysis of women who were given HRT below the age of 60 or within 10 years of the menopause did show a reduction in the risk of myocardial infarction and death from any cause while also showing an increased risk of blood clots and possibly stroke
