Medical Therapy after Successful Percutaneous Coronary Revascularization
Article Abstract:
Coronary artery balloon angioplasty (PTCA) substantially reduces chest pain in patients with coronary artery disease, but does not significantly reduce the need for antianginal drugs. Researchers evaluated 3,831 patients successfully treated with angioplasty. Six months after the procedure, only 12% of patients had severe chest pain, whereas 66% had severe chest pain before PTCA. Although 69% of patients were free of chest pain, 39% continued to use beta-blocker drugs, 36% used nitrate medications, and 57% were using calcium-channel blockers.

Benefits of coronary stents
Article Abstract:
Coronary stents may be better in some ways than angioplasty but they are no more likely to improve survival or prevent heart attacks in patients with coronary artery disease, according to researchers who analyzed 29 studies covering 9,918 patients. Stents are small cylinders that are placed inside arteries to keep them open. Angioplasty uses a balloon for this purpose but the artery can become blocked again.

Why have stents replaced balloons? Underwhelming evidence
Article Abstract:
A coronary artery stent may not be suitable for all patients with coronary artery disease. In some cases, angioplasty may be more appropriate, depending on the severity of the disease and which artery is blocked. A stent is a small cylinder that is placed inside an artery to keep it open. Angioplasty uses a balloon to open blocked arteries.
