Abstract

Fifty-five % (73/133) of myocardial infarction (MI) patients on Cape Cod during a three-month period reached the hospital by ambulance. The 45% (60/133) not using ambulances were compared to users to identify a subpopulation to which public health programs might be directed to increase appropriate use of cardiac ambulances. Univariate analyses showed a distance of more than ten miles from the hospital, and a prior history of MI distinguished ambulance users from non-users. Demographic/economic status, delay in seeking care, presenting symptoms, Killip class, and in-hospital mortality rates were not significantly different. Stepwise discriminant analysis identified four predictive variables in rank order: distance from the hospital, past history of MI, symptoms of fainting, and negative history for hypertension which correctly classified 72% of our population with respect to ambulance utilization.
