Abstract Background The Charlson's is the most used comorbidity index. It comprises 19 comorbidities, some of which are infrequent in elderly patients with acute coronary syndrome (ACS), while some others are manifestations of cardiac disease rather than comorbidities.

Comorbidities were assessed selecting those medical disorders other than cardiac disease that were independently associated with mortality by multivariab…
