Abstract
Background: Off-pump total arterial coronary revascularization (OPCAB) is a significant cardiac surgical procedure whose outcomes can be influenced by various preoperative factors. This study aimed to evaluate the predictive value of demographic, clinical, biochemical, and echocardiographic parameters on postoperative outcomes following OPCAB.
Methods: This observational study included 138 patients undergoing OPCAB. Preoperative factors such as age, BMI, comorbidities, echocardiographic parameters (LVEF and MPI), and laboratory values were analyzed in relation to postoperative outcomes, particularly major adverse cardiac events (MACE).
Results: Older age (65 ± 7 vs. 62 ± 8 years, P=0.045) and higher BMI (28 ± 4 vs. 27 ± 3.5, P=0.042) were significantly associated with poor outcomes. Comorbidities like hypertension, smoking, and diabetes were more prevalent in the poor outcome group. Echocardiographic parameters showed that a lower LVEF and a higher MPI were associated with adverse outcomes. The length of ICCU stay was negatively correlated with LVEF (-0.45, P<0.001) and positively with MPI (0.52, P<0.001).
Conclusion: The study highlights the critical role of comprehensive preoperative assessment, including echocardiographic evaluation, in predicting outcomes post-OPCAB. It underscores the importance of considering a combination of traditional risk factors and advanced echocardiographic parameters for optimal patient management and risk stratification.
