The Bypass Angioplasty Revascularization Investigation (BARI)

The Bypass Angioplasty Revascularization Investigation (BARI) was a large study comparing two procedures for treating blocked coronary arteries: coronary artery bypass surgery and angioplasty with stents. The goal was to see which method was more effective in preventing heart attacks and improving survival, especially in patients with significant artery blockages. Results showed that for some patients, bypass surgery had better long-term outcomes, particularly those with more severe blockages. The study's findings help doctors decide the most appropriate treatment option based on a patient's specific condition, advancing personalized care for coronary artery disease.
