A five-year study by Yale researchers found that nearly all heart attack patients were receiving angioplasty within 90 minutes of hospital admission, with a significant improvement from 44% in 2005 to 91% in 2010. This rapid progress was attributed to nationwide efforts to accelerate treatment and improve care for patients.
A new study suggests that coronary artery calcium (CAC) is a more accurate predictor of heart attacks and strokes than C-reactive protein (CRP) in healthy adults. High CAC scores are associated with a fourfold increased risk of cardiovascular disease, while low scores indicate an extremely low risk of events. Statin treatment may be mo...

A Johns Hopkins study found that CT angiography in low-risk patients without symptoms leads to more aggressive care, including more drugs and tests, but no difference in heart attack or cardiac death rates. The test's benefits are unclear, and guidelines suggest it should not be used for screening in low-risk patients.
A new study published in Nutrition, Metabolism and Cardiovascular Diseases found that high levels of saturated fat in dairy products do not increase the risk of heart attack. Instead, other nutrients in dairy products, such as calcium and conjugated linoleic acid (CLA), may have protective effects against heart disease.
A recent meta-analysis suggests that elevated levels of cardiac troponin T or I following elective angioplasty are associated with a higher risk of all-cause mortality and long-term adverse events such as heart attack. Routine monitoring of these protein levels could improve long-term outcomes for patients.
Researchers found a relationship between discretionary heart failure admissions and higher readmission rates. Hospitalization after heart attack shows no correlation with readmission rates, contrary to expectations.
