The study highlights a need for better education and counseling on heart disease prevention among young individuals, particularly women.
Research published in the American Heart Association journal found that young women are less likely to be prescribed or fill their medication after a heart attack. Despite being eligible for the same treatment as men, only 65% of women under 55 initiated treatment on all appropriate drugs, similar to men.
A new tool has been developed to identify unstable atherosclerotic plaques at greatest risk of rupture, a major contributor to heart attacks and strokes. The tool uses fluorescent probes to detect the severity of plaques and shows high sensitivity and specificity in distinguishing high-risk plaques from stable ones.
A large study found that exercise and stopping smoking had the strongest association with improved depression after a heart attack. Patients who quit smoking had a 2.3 greater chance of improving their depression, while those who were already physically active at the beginning of the study were more likely to improve their symptoms.
Researchers identified a troponin threshold below which patients are at very low risk of heart attack and may be eligible for early, safe discharge. Using this approach could reduce unnecessary hospital admissions and provide substantial cost savings.
