Why the study?
Does a new computer-generated coronary index correlate with clinical variables, ventricular function, and mortality in patients with coronary artery disease?
Does a new computer-generated coronary index correlate with clinical variables, ventricular function, and mortality in patients with coronary artery disease?
A newly designed computer-generated coronary index correlates with clinical variables, ventricular function, and mortality, offering a potentially more sensitive classification than standard vessel disease counting.
May refine CAD severity assessment beyond vessel count; leaves open prospective validation before clinical use.
Mortality in patients with coronary artery disease is related to its severity. The commonly used classification of 1, 2 or 3 vessel disease is relatively insensitive. We have designed a new classification which takes into account site, severity and effect of multiple lesions in the coronary circulation. Data is recorded on Mark Sense computer cards and a coronary index (CI) obtained. We have collected data from 1100 patients and shown correlations of the index with clinical variables, ventricular function and in particular, mortality.
