Selective coronary arteriography. Risk in a community hospital.
Over a 33-month period, selective coronary arteriography was performed in 627 consecutive patients in a 385-bed, non-university-affiliated community hospital. Mortality was 0.16% (one death); there was also one nonfatal myocardial infarction. No deaths or myocardial infarctions occurred in the last 369 consecutive patients in this series when routine systemic heparinization was introduced. Substantially greater risk of mortality (2.6%) and nonfatal myocardial infarction (2.6%) was encountered in an earlier series of 78 consecutive patients for whom a different protocol was used. It included extensive exercise hemodynamic studies with the use of percutaneous arterial angiographic catheters, without systemic heparinization. This indicates that coronary arteriography can be carried out with acceptable risk in a community hospital. Protocols should be designed to minimize the time that catheters are in the arterial system. Systemic heparinization may reduce the risk of procedure-related death and myocardial infarction.
