ABSTRACT
Objective To evaluate the possible effect of percutaneous transluminal coronary angioplasty(PTCA) on myocardial injury. Methods Serum cTnI and CK MB levels were measured in 173 patients with coronary artery disease undergone PTCA before and 6, 12, 24, 48 and 72 hours after the procedure. Cardiac events during follow up in these patients were recorded. Results Serum cTnI level was increased after PTCA in 42 patients, remained normal in 84, and was over baseline level before and after the procedure in 47. Serum CK MB level was above baseline before and after the procedure in one patient and increased in 10. Compared with normal cTnI group, elevated cTnI was related to total balloon inflation time, total pressure, number of dilation and stents deployed, contrast medium dose and occurrence of angina during balloon inflation ( P 0.05). Conclusion cTnI was more sensitive and specific than CK MB in identifying minor myocardial injury during PTCA. This injury was related to the intensity of PTCA, but not enough to make worse influence on overall outcome.
