Abstract
Over the last decade, the practice of surgical revascularization for the coronary artery disease has been popularized in Bangladesh. Our aim was to compare the outcome of non-cardioplegic versus cardioplegic coronary artery bypass surgery in terms of early postoperative outcomes. A literature search was conducted in March 2020 on Medline (via PubMed), Scopus and Bangladesh Journal Online electronic databases according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. All randomized controlled trials and observational studies reporting findings of coronary revascularization surgery comparing the outcomes were included. Fifteen studies were used quantitatively that included a total cohort of 4750 coronary artery bypass graft (CABG) patients in Bangladesh. After the meta-analysis, we observed a longer duration of operating time [mean difference (MD): - 52.30, confidence interval (CI): - 67.73 to - 36.86, I 2 18 = 89%, p < 0.00001] and a higher incidence of postoperative atrial fibrillation [risk ratio (RR): 0.43, CI: 0.14 to 0.80, I 2 = 44%, p = 0.01] in the cardioplegic CABG group as compared with the non-cardioplegic group. Additionally, statistically significant longer duration of ventilation time (MD: - 8.64, CI: - 9.47 to - 7.82, I 2 = 82%, p < 0.00001) and ICU stay (MD: - 17.25, CI: - 33.36 to - 1.14, I 2 = 99%, p = 0.04) was observed in the cardioplegic group. No significant differences in number of grafts and in-hospital mortality were found between the two groups. Non-cardioplegic CABG may be a viable alternative to cardioplegic CABG in Bangladeshi population, providing similar postoperative outcomes but offering additional advantage of shorter operation and ventilation times.
