Stent placement compared with balloon angioplasty for obstructed coronary artery disease in Thai elderly patients: initial result and 6 months follow-up.

Unlabelled: Percutaneous Old Balloon Angioplasty (POBA) is accepted worldwide for the treatment of obstructive coronary artery disease because this technique is safe, and quick and the patient may return to work earlier than with bypass surgery (particularly elderly patients). But the major problem with POBA is restenosis which occurs between 20-40 per cent. Stent placement has been reported to reduce the restenosis rate to 10-20 per cent.
