Abstract:

OBJECTIVE

To establish the criteria of reversible impairment of myocardial contractility in patients with coronary artery disease (CAD) after coronary artery bypass grafting considering cardiac MRI and echocardiography data.

MATERIAL AND METHODS

We studied the results of coronary artery bypass grafting in 186 patients with CAD complicated by severe left ventricular systolic dysfunction (ejection fraction< 30%). All patients underwent cardiac MRI and echocardiography before surgery. Immediate and long-term results were evaluated according to echocardiography and MRI data.

RESULTS

We confirmed the role of the previously established predictors of LV contractility improvement, i.e. diastolic IVS thickness ≥10.5 mm and LV posterior wall thickness ≥9.5 mm, as well as total score of LV damage according to cardiac MRI data (p<0.05). Multivariate analysis together with combination of discriminant analysis formulas is valuable to calculate prognostic index regarding postoperative myocardial contractility with an error of 6%.

CONCLUSION

Echocardiography and contrast-enhanced cardiac MRI make it possible to assess the morphological and functional state of the left ventricle in patients with ischemic cardiomyopathy. Moreover, we can estimate myocardial reserves regarding improvement of contractility at the preoperative stage.
