Angioplasty study challenges 12-hour window

The limited study suggests that patients who get the procedure within 48 hours may suffer less muscle damage to the heart. According to one estimate, up to 40 percent of heart attack sufferers seek treatment outside the 12-hour window. Experts called the finding intriguing, but said more research is needed.
