Abstract: A nationwide survey was undertaken to determine the rate of complications due to coronary arteriography during 1970-71. The responses from 173 hospitals-including a total of 46,904 coronary arteriograms-were analyzed in relationship to the technique employed and to the number of examinations performed at each hospital during the two-year period. The overall mortality rate was 0.45% (brachial 0.13%, femoral 0.78%). The mortality rate in institutions performing fewer than 200 examinations per two years was eight times higher than in institutions performing more than 800 examinations per two years. Similarly, the incidence of myocardial infarction and cerebral embolism was significantly higher when a smaller number of examinations was performed. The incidence of major complications-including death, myocardial infarction, and cerebral embolism-was higher in examinations using the femoral approach than the brachial approach. The incidence of arterial thrombosis and contrast agent reactions was higher for the brachial approach. Factors which may help to explain these differences are considered and discussed.
