Abstract
ObjectiveTo summarize the clinical features of patients with diffuse coronary artery diseases, and evaluate the clinical efficacy of off-pump coronary artery bypass grafting(OPCABG) combined with selective coronary venous bypass grafting(SCVBG).
MethodsRetrospectively analyzed the clinical data of 61 patients with diffuse right coronary stenosis undergoing operation of OPCABG+ SCVBG from January 2007 to December 2013, and conducted the comparative study of the patients who underwent OPCABG during the same period based on propensity score. Patients were divided into SCVBG group(61 cases, underwent OPCABG+ SCVBG) and control group(60 cases, matched by propensity score and underwent OPCABG without SCVBG).
ResultsCompared with control group, the rate of myocardial infarction in SCVBG group was higher(67.2% vs. 46.7%, P<0.05), the heart rate was faster[(69.92±15.82)bpm vs.(64.48±13.72)bpm, P<0.05], the low density lipoprotein and triglyceride were higher[(2.67±0.78)mmol/L vs.(2.37±0.78)mmol/L, (1.84±0.79)mmol/L vs.(1.36±0.60)mmol/L, both P<0.05] and the troponin I was higher in the first postoperative day[0.85(0.29, 3.15)μg/L vs. 5.09(2.02, 13.03)μg/L, P<0.05]. The perioperative(postoperative) mortality(1.6% vs. 0) and the long-term survival curve difference had no statistically significance(P>0.05).
ConclusionPatients with coronary artery disease should pay more attention to the control of heart rate and blood lipids, poorly controlled heart rate and high blood lipids are the important factors for the development of coronary heart disease. The exact efficacy of selective coronary vein arterialization for diffuse coronary artery disease is confirmed through the small sample comparative study.
