[Heart complications in general surgery: results of a multicenter study]

Cardiac events are the most dangerous postoperative complications since they may be easily followed by the death of the patient. The related risk factors were prospectively evaluated in a study of 1182 patients. Stepwise regression logistic model was employed for statistical analysis. Preoperative cardiac and respiratory failure, ventricular arrhytmias, compromission of the nutritional status, presence of neoplastic disease and prolonged anesthesia over two hours were the only significative factors related to postoperative cardiac complications. Advanced age was not a major risk factor. The results of the study require a prospective validation. They are however comparable to those observed in the literature Preoperative cardiac evaluation is of utmost importance for cardiac prognosis and various instrumental, sometimes invasive diagnostic procedures have been proposed. The Authors provide a usefull, simple and widely employable system of general and cardiac assessment for the determination of cardiac risk.
