Abstract:
Objective To investigate the early and long-outcomes of coronary artery bypass grafting(CABG) in acute myocardial infarction (AMI) patients with coronary artery disease(CAD)(age≤45 years). Methods Data of 596 adult CAD patients (include AMI and Angina) who underwent CABG in our hospital were collected retrospectively from May 2010 to October 2018. In an AMI group, 234 were male patients with an average age of 41.59±3.79 years; 26 were female patients with an average age of 41.64±3.03 years. In an angina group, 280 were male patients with an average age of 42.19±2.90 years; 56 were female patients with an average age of 41.54±3.52 years. Preoperative baseline variables, perioperative mortality, major adverse cardiac and cerebrovascular events (MACCE) were compared between two group. Results There was no significant difference in all preoperative variables. Seven patients were died and the hospital mortality rate was 1.23% (1.54% vs. 0.89%, P=0.477). The complications including reoperation for bleeding, cerebral infarction, renal failure and atrial fibrillation arrhythmia were without significant difference between two group (P>0.05). The intensive care unit stay duration (30.66±27.46 h vs. 23.96±15.11 h), intubation duration (22.54±22.31 h vs. 18.64±11.81 h) and hospitalization costs (97 186±33 741¥ vs. 90 081±24 537¥, P=0.003) were greater in the AMI group. The hospital mortality rate and complications rate were without significant difference between STEMI (ST segment elevated myocardial infarction) and NSTEMI (non-ST-segment elevated myocardial infarction) subgroups (P>0.05). The follow-up rate was 92.6% (546 patients) and the follow-up time was 4 (0.5 to 8.5) years. All cause-mortality rate was 3.85%(21 patients), and freedom MACCE was 72.2%. The freedom from MACCE, recurred angina and cerebral infarction were without significant difference, but AMI was associated with higher rate of PCI procedure. Conclusion CABG procedure in CAD patients under 45 years accompanied AMI is safety and reliable both in early and the long-term outcomes.
