Incidence Rate of Post Coronary Artery Shunt Complications; Age Dependent!

Abstract

Background: Post-coronary artery shunt remains one of the most frequently used revascularization in emergency. Aims: Asses the role of age advancement in the incidence rate of post coronary artery shunt complications. Objectives: Several complications are reported after coronary artery bypass graft (CABG) surgery, such as postoperative arrythmia and postoperative stroke. However, the risk factors for the development remain not elaborated. Materials and methods: Retrospective analysis of the 290 patients who underwent coronary artery bypass graft from the Mordovia republic hospital for the period of 2017-2021. The results of the descriptive statistics demonstrated age dependent complications. Therefore, the sample subdivided into two groups, first group 126 patients (mean age: min; max, 55.21:41.00;60.00) and the second group 163 (M age: min; max, 66.11: 61.00; 80.00). For statistical analysis, we used the T test, one-way ANOVA test, and Pearson correlation test by using the Statistica 12 programme. Results: Post-CABG arrythmia developed in elderly patients, t-value -2.51307, p<0.012528. Subsequently, post-CABG arrythmia increased ICU and total hospitalisation days, t value -5.83306, p< 0.000000; t-value -4.02907, p< 0.000072, respectively. Elderly people are at higher risk of psychosis after CABG surgery, t value 2.69885, p <0.007379. psychosis significantly increases hospitalisation days in the ICU, t-value 3.86094, p < 0.000140. Postoperative stroke occurs more frequently in elderly people, t-value 2.087585, p < 0.037736. Subsequently, postoperative stroke increases the ICU hospitalization days, t-value 3.409293, p <0.000747. The number of ITAs used is less in the elderly people, t-value 2.41992, p < 0.016145. In terms of correlation, exist a direct association between age and ICU / total hospitalization days/number of complications, r= 0.189046, 0.141415, 0.138565; respectively. Conclusions: The number of complications is determined by age increase, CPB time, aortic cross-clamp time, the days of hospitalization in the ICU and total hospitalization days. Elderly people undergoing CABG are at higher risk of psychosis, arrythmia, longer total and ICU hospitalization days, and stroke. Others: Total hospitalization days depend on the presence of arrythmia, which is commonly seen in elderly patients > 63 years old.
