[Assessment of surgical treatment in patients with severe depressed left ventricular function].
The aim of the study was to analyze perioperative risk factors, with special attention to cardioprotective techniques. Additionally we compared effectiveness of standard risk scales (Cleveland and Canadian) and own risk scale (modified by inclusion Graham, Chambers, Davies classification of distal coronary arteries) in investigated group. The obtained data indicate that cardioprotective techniques have no impact on clinical results but there are some important factors which influence surgical treatment: age (over 75 years), ejection fraction less than 20% and poor distal parts of coronary vessels. The regression model results were used to calculate predictive value of Cleveland or Canadian risk scale (measured area under ROC curve). Effectiveness of anticipation: mortality (Cleveland and Canadian), complications, ICU and hospital stay in patients with severely depressed left ventricular function achieved 71%, 70%, 70%, 71%, 69%, respectively. After including Graham, Chambers, Davies classification of distal coronary arteries predictive value improved 3-4% and thereby raised to 74%, 73%, 74%, 74% and 72%.
