A study of 3,010 heart attack patients found that 40% were rehospitalized within 30 days due to the heart attack or other causes, with comorbid conditions like diabetes and COPD increasing risk. Additionally, half of heart patients make serious medication errors, even when pharmacists intervene.
Researchers found that the immune response to a heart attack accelerates underlying atherosclerosis, leading to increased inflammation in atherosclerotic plaques. This study suggests a new therapeutic strategy for preventing heart attacks and strokes by targeting the immune system's role in exacerbating atherosclerosis.

Participants with atherosclerosis who lived alone had a higher rate of death over four years compared to those who did not live alone.
A large-scale Canadian study has found that patients with chronic kidney disease are at comparable risk of future coronary events to those who have previously suffered a heart attack. This could lead to targeted treatment for high-risk individuals, including the use of statins to reduce 'bad' fats in the bloodstream.
Scientists at Joslin Diabetes Center have identified a new cause of cardiac damage after heart attacks in people with type 1 diabetes.
