    Abstract:
    In a series of 129 patients having coronary angioplasties in St. James's Hospital in 1989, the average age was 54.8 (30-77 years). There were 102 (79%) men and 27 (21%) females. Clinical indications were unstable angina 62, stable angina 26, post myocardial infarction 39 and asymptomatic ischaemia 2. The distribution of coronary disease was single vessel 62%, double vessel 28%, triple vessel 7% and previous coronary bypass surgery 3%. Only 10 patients had more than one vessel dilated. Primary success was achieved in 119 (92%), there were no deaths, 3 patients had abrupt closure of the vessel during angioplasty and sustained a nonfatal myocardial infarction, 1 patient required urgent bypass surgery and 2 patients had peripheral vascular complications requiring surgery. There were 6 failed angioplasties, 4 of which had chronic total occlusion. At a mean follow-up of 5.3 months, 85 patients had no symptoms, 34 had angina, 2 developed myocardial infarction and 1 died suddenly at 5 months. Repeat angiography was performed in 96 (79%) patients. At follow-up, no symptoms were present in 69% of those with single vessel disease and 70% of multivessel disease. Of those who had more than one vessel dilated in multivessel disease, 80% were asymptomatic (P = NS). There were 11 patients with initial total occlusion at presentation, 4 had failed angioplasties, 5 recurrent angina of which 4 reoccluded and 1 restenosed and only 2 were asymptomatic and without restenosis. Angioplasty was performed with primary success (92%) and follow up results (70% asymptomatic). Those with single or multivessel disease had similar clinical outcome, favouring the use of target vessel angioplasty. Long term results following angioplasty of chronic total occlusions were poor and suggests the need for additional treatment.
