The study found that drug-eluting stents are safer and more effective than bare metal stents in preventing deaths and heart attacks. Over a two-and-a-half-year follow-up period, patients who received drug-eluting stents had a 25% reduction in death and a 24% reduction in heart attacks.
The study found that delivering a potent form of autologous adult stem cells into the heart muscle of patients with severe angina improved exercise tolerance and reduced episodes of chest pain. Six months after the procedure, treated patients were able to walk longer on a treadmill than those in the placebo group.
Researchers found that surgical ventricular reconstruction did not improve patients' survival or quality of life, but increased hospitalization costs. The study compared outcomes between patients who received bypass surgery alone and those with added SVR, revealing no significant difference in quality of life measures.
