[Transluminal coronary angioplasty at the same time as or separate from coronarography. Comparative results].
Frequency of PTCA performed at the time of initial coronary angiography has increased to 47% of all PTCA performed in 1988. The aim of this study is to assess the efficacy and safety of this strategy by comparing the results in 2 groups of patients: in group 1 (179 patients), PTCA was performed at the time of initial coronary angiography and in group 2 (549 patients) PTCA was performed, 15 to 30 days after initial coronary angiography. Clinical differences between the two groups concerned: stable angina (25.1% vs 41%; p less than 0.001) and myocardial infarction treated with thrombolytic therapy (23.7% vs 7.7%; p less than 10(-9)). The extent of coronary artery disease was similar in the two groups but the incidence of single vessel PTCA was higher in group 1 (96% vs 90%; p less than 0.01). The immediate results of PTCA were similar and led us to develop this strategy for unstable angina, myocardial infarction treated with thrombolytic therapy, as well as total coronary obstruction and restenosis whatever their symptoms and signs. This strategy requires high quality fluoroscopic and video replay images, and allows a reduction in hospital costs.
