Myocardial Performance Index Predicts Mortality in Lung Resection Surgery

Objective: Cardiac and pulmonary involvement affects morbidity and mortality after lung resections.Studies have shown that patients have increased pulmonary artery pressure (PAP) and right ventricular (RV) dilatation after resection.Myocardial performance index (MPI) is a numerical value obtained using cardiac time intervals.It has a prognostic importance independent of heart rate changes in different clinical situations.The main purpose of this study is to show the prognostic value of MPI in predicting mortality and morbidity.Methods: This prospective study included 44 patients who applied to the thoracic surgery department between October 2014, April 2015 underwent lung resection.In the early postoperative period, pulmonary, cardiac functions of the patients were evaluated using noninvasive methods. Results:The mean age was 59.16.3 years, (39male-5female).Lobectomy was performed in 37 patients and pneumonectomy was performed in 7 patients.Prolonged air leak, atrial fibrillation, pneumonia, hemorrhage requiring re-thoracotomy, bronchovascular fistula, cerebrovascular infarction were recorded as postoperative complications.Average hospital stay was 8.83.6 days.When the effects of gender, age, echocardiography reports on morbidity and mortality were examined, mortality was found to be significantly higher in patients with a change of MPI in the first week more than 0.11 (p=0.022). Conclusion:In our study, the amount of change in MPI in the early period after lung resection was found to be an important and independent variable in predicting mortality and probability of cardiovascular events of patients.Future studies are needed to test these results in larger populations.
