Whether the presence of on-site coronary angiographic facilities (CAF) influences the use of invasive coronary procedures and the outcome of acute myocardial infarction in coronary care units was studied. A prospective survey was conducted early in 1992 when 1014 consecutive patients with acute infarction were admitted. Of them 707 (70%) were admitted to coronary care units of hospitals with, and 307 (30%) without CAF. Thrombolytic therapy was given to 46% in both groups. Those admitted to hospitals with CAF underwent more coronary angiographies (26%) and percutaneous transluminal angiography and/or coronary artery bypass grafting (12%) than those without CAF (10 and 5%, respectively--p < 0.005). In-hospital and 1-year mortality were 11 and 18% respectively in those with CAF, vs 10 and 11%, respectively, in those without CAF. All patients treated with a thrombolytic agent had similar mortality, unrelated to the availability of CAF. The survey showed that the availability of on-site coronary angiography facilities led to greater use of invasive coronary procedures in cases of acute myocardial infarction, but there was no significant difference in mortality.
