[Surgical cardiac risk in patients with heart diseases. I. Evaluation of the risk].
To evaluate the cardiac risk in patients undergoing noncardiac surgery, it has been identified by the multivariated analysis some major and independent correlates of fatal or life-threatening cardiac complications. The most important ones were the history of previous myocardial infarction in the preceding six months, clinical signs of congestive heart failure, third heart sound or jugular venous distention, and for some Authors instable angina class IV CCS. Other predictive factors of complications were premature ventricular and atrial contractions or ectopic rhythms within cardiac diseases, age over 70 years, intraperitoneal, intrathoracic, aortic or emergency operation, severe valvular aortic and mitral stenosis and poor general medical conditions. Stable angina, hypertension, hyperlipidemia and smoking habit were less important. The global evaluation of cardiac risk can be performed by multifactorial index subdividing the patients into four very different risk classes. This is obtained by scores assigned to each statistically significant factor.
