Abstract
PTCA has been widely applied in patients with symptomatic coronary artery disease since 1977. The PTCA was performed on a total of 25 patients (19 men and 6 women) from Feburary 1988 to January 1990 at Inje University Baik Hospital. Their mean age was 51.4±10.1 years. The 20 patients had unstable angina, and 5 patients had stable angina. The 6 patients had a previous myocardial infarction. The 17 patients had one vessel disease, 6 patients had two vessel disease and 2 patients had three vessel disease.
Primary success was achieved in 24 of 25 patients. The mean degree of stenosis was reduced from 80.7±2.9% to 16.2±3.3% (p<0.01). After PTCA, pain was relieved or subsided in all patients. In 6 patients, mild chest pain has reccured during the short term follow up. Repeat PTCA was performed in 2 of 6 patients successfully. Complications occurred in 3 patients ; coronary artery spasm, ventricular fibrillation and femoral artery hematoma in each patients.
