“…Diabetes and hypertension are common comorbidities in patients with chronic renal disease and cardiovascular diseases. Diabetes [ 33 ] and arrhythmias, especially atrial fibrillation [ 16 , 34 ], are prevalent in patients with coronary disease who undergo CABG. In agreement with a prior study [ 35 ], we found that prediabetes was associated with a higher mortality rate than nondiabetes after CABG.…”

“…On the other hand, some studies have reported lower mortality and fewer adverse cardiovascular events and hospital readmissions after CABG in overweight patients [ 13 , 14 , 15 ]. Postoperative complications such as atrial fibrillation [ 16 ] and acute kidney injury [ 17 ] are associated with higher short-term and long-term mortality after CABG, as well as longer stays in the intensive care unit and hospital [ 2 ]. However, few studies have examined the modifiable risk factors for early death after CABG in Iranian patients with coronary artery disease [ 18 , 19 , 20 ], and none have focused on long-term outcomes.…”

Modifiable risk factors play an important role in the premature mortality among patients undergoing coronary artery bypass grafting (CABG). The aim of this study was to examine the factors that influence the early death of patients who had CABG. We conducted a prospective cohort study and followed 2863 patients after their CABG, and collected data on their characteristics and blood tests. We used the Cox proportional hazards regression model in Stata, version 16, to identify the predictors of early mortality. Out of 2863 patients, 162 died during the follow-up period. The survival rate was 99.2% within the first three days after the surgery, 96.2% from the fourth day to the end of the first year, 94.9% at the end of the second year, and 93.6% at the end of the third year. After adjusting for confounding factors, we found that older age (hazard ratio [HR] 1.05, 95% CI 1.02, 1.08 for one year increase in age), obesity (HR 2.16, 95% CI 1.25, 3.72), ejection fraction < 50% (HR 1.61, 95% CI 1.06, 2.44), number of rehospitalizations (HR 2.63, 95% CI 1.35, 5.12 for two or more readmissions), history of stroke (HR 2.91, 95% CI 1.63, 5.21), living in rural areas (HR 1.58, 95% CI 1.06, 2.34), opium use (HR 2.08, 95% CI 1.40, 3.09), and impaired glomerular filtration rate increased the risk of early death after CABG, while taking a beta-blocker (HR 0.59, 95% CI 0.38, 0.91) reduced the risk. We conclude that modifiable risk factors such as excess body mass, high blood glucose, opium use, and kidney dysfunction should be monitored and managed in patients who had CABG to improve their survival outcomes.
