The Experience of Percutaneous Transluminal Coronary Angioplasty (PTCA) on the 25 Patients with Coronary Artery Disease

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.
