Key result
Surgical revascularization in severe LV dysfunction is associated with ~10% hospital mortality.
Why the study?
Patients with coronary artery disease and severe left ventricular dysfunction undergoing surgical myocardial revascularization carry high operative risk, prompting evaluation of their short- and long-term morbidity, mortality, and predictive factors.
Does surgical myocardial revascularization improve survival and symptoms in patients with coronary artery disease and severe left ventricular dysfunction?
Observational (n=74)
No
Does surgical myocardial revascularization improve survival and symptoms in patients with coronary artery disease and severe left ventricular dysfunction?
Surgical myocardial revascularization in patients with severe left ventricular dysfunction is associated with acceptable long-term survival and functional improvement despite high operative risk.

May support revascularization in severe LV dysfunction despite risk; leaves open randomized confirmation versus medical therapy.
Patients with coronary artery disease associated with severe left ventricular dysfunction, candidates for surgical myocardial revascularization, are with high operative risk. The aim of this study was to assess short and long-term morbidity and mortality and to identify their predictive factors. Methods: We conducted a retrospective study in the cardiac surgery department of the Military Instruction Hospital Mohammed V- Rabat, between 2000 and 2015. The statistical analysis was executed by SPSS. There were 74 patients (mean age 74±10 years, ejection fraction [FE]: 30.07%±4 .5, Euroscore: 6.6±2.9). Results: Hospital mortality was 9.5%, with a follow up time of 59.2 ± 36 months. The survival rate at 10 years was 57%. There was also an improvement in their clinical symptoms and echocardiographic parameters (postoperative FE: 40.36%±11.2). Conclusion: In this group of patients with high operative risk, the long-term results of several studies demonstrate the superiority of surgical treatment on medical treatment.

Abdou et al. (2020) conducted an observational in Coronary artery disease with severe left ventricular dysfunction (n=74). Surgical myocardial revascularization (CABG) was evaluated on Hospital mortality. Surgical myocardial revascularization in patients with severe left ventricular dysfunction resulted in a hospital mortality of 9.5% and a 10-year survival rate of 57%.
