Comparative Clinical Outcomes of Coronary Artery Bypass Grafting and Percutaneous Coronary Intervention in Patients with Coronary Disease

This study was to examine how post- surgical complications affect quality of life of patients who have undergone either Coronary Artery Bypass Grafting (CABG) surgery as well as Percutaneous Coronary Intervention (PCI) surgery. A quantitative research design was used and 300 cardiac patients had been sampled, 150 patients per group (CABG and PCI). Purposive sampling method was also used where relevant participants were involved. The analyses of the data were carried out by Pearson correlation, ANOVA, and chi-square procedures with the help of SPSS software. The correlation analysis revealed significant moderate negative association between post-operative complication and quality of life in the complete sample (r = -0.463, p < 0.01). This implies that, the more the complications, the poorer the quality of life of patients. The CABG group had a stronger negative correlation when tackled independently (r = -0.492) than the PCI group (r = -0.421), meaning that the CABG patients were yet more affected by complications on their quality of life. ANOVA indicated the limitation of a significant difference between the two groups in recovery time (F = 9.76, p < 0.01), with PCI patients taking shorter time to recover. Chi-square test also demonstrated a significant relationship between the nature of the surgery and the presence of the complications (2 = 11.420, p = 0.001). These results pinpoint that the kind of surgical intervention one is subjected to does not just affect the length of time taken to recuperate but also affect post-surgery results and the general well-being of the patient. The findings can assist medical professionals in managing patients to better care and reducing the instances of complications particularly among the patients with high risk cases.
