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...

However, many participants were unwilling or uncertain about taking medications with mild adverse effects, highlighting the need for emphasis on both benefits and harms in clinical guidelines.
A Yale University study found that older adults are unwilling to take medications for heart disease prevention if they have potential side effects, such as fatigue or nausea. In contrast, most participants would take the medication if it had no adverse effects and offered an average risk reduction.
Medications like Vioxx, Bextra, and Avandia increase heart attack and stroke risk due to fluid retention. The study suggests the FDA should require verification of cardiovascular safety for all medications causing fluid retention.
