title: [Coronary angioplasty: experience at the University Hospital of Madrid].
abstract: The results of 963 consecutive coronary angioplasties, with 1.135 lesions attempted in 816 patients, were prospectively analyzed. Initial angiographic success (residual stenosis less than 50%) was achieved in 1.017 lesions (89.6%), and final success was obtained in 838/963 procedures (87%). Major complications included: emergency surgery in 4 cases (0.4%), acute myocardial infarction in 28 (2.9%), and death during hospitalization in nine (0.9%). Surgical stand-by was required only for cases with vital risk should the attempted vessel occlude. This criteria was present in 230 (23.8%) angioplasties. Coronary angioplasty was performed during the diagnostic procedure in 300 (31.1%) case, with final success in 264 (88%) of them. A exercise test was achieved before the procedure in 419 (50%) successful angioplasties and in 246 (58.7%) of them it was abnormal because of angina (with or without ST depression). After procedure, exercise could be performed in 780 cases (93%), and the result remained unchanged in only 44 (5.6%) (p less than 0.01). At discharge 780 (93%) patients with final success considered themselves clinically improved. In our experience, coronary angioplasty is a good myocardial revascularization technique, with high success, low rate of major complications, and that provides a good clinical outcome. Surgical stand-by may be unnecessary in prost of angioplasty procedures if patients selection is carefully done, also, this approach makes it possible to perform angioplasty at time of diagnostic catheterization.
