Retrospective analysis of percutaneous transluminal coronary angioplasty and coronary stenting.

AbstractOBJECTIVE:
To examine long-term efficacy of percutaneous transluminal coronary angioplasty (PTCA), coronary stenting and to assess the factors affecting its efficacy.
METHODS:
A total of 790 patients who underwent successful PTCA and PTCA + stent in this hospital were followed by direct interview or letter. The rate of follow-up was 84.2% and the period of follow-up was 0.9 - 12.7 (3.5 +/- 2.4) years.
RESULTS:
During follow-up, 4 (0.5%) patients died, 22 (2.8%) had nonfatal acute myocardial infarction, 10 (1.3%) had coronary artery bypass surgery, and 98 (12.4%) had repeat PTCA. The rate of recurrent angina pectoris was 31.1%. The cardiac event-free survival rate calculated by the Kaplan-Meier method was 88.2% at 1 year and 80.6% at 12.7 years. Cox regression analysis showed that there was a positive correlation between AMI history, stent implantation and the risk of cardiac events, and there was a negative correlation between the number of diseased arteries and the risk of cardiac events. Compared to the PTCA group, patients with PTCA + stent had significantly lower rates of total cardiac events.
CONCLUSION:
The long-term efficacy of PTCA, especially PTCA + stent in Chinese patients was very satisfactory, suggesting that PTCA + stent therapy should be the major treatment for revascularization in patients with coronary heart disease.
