AbstractCoronary artery bypass graft (CABG) and percutaneous transluminal coronary angioplasty (PTCA) are treatments of choice for coronary artery disease. Quality of life (QoL) is an important factor in determining optimum treatment. This study was aimed to compare changes in QoL, six months post procedure, between CABG and PTCA, and to understand the confounding effect of various contributing factors. Thirty stable angina patients each in CABG and PTCA groups, were followed up for six months. QoL was assessed with WHO-QoL-BREF. Depression was rated on the Hamilton Depression Rating Scale. Changes in QoL and depression within and between CABG and PTCA groups were compared. Multinomial logistic regression was used to measure the predictive strength of treatment type (CABG and PTCA) on QoL, controlling for significant confounders. Although scores of QoL and depression significantly changed over time in both the groups, time×group interaction did not reach to a significance. Significant confounding effects of diabetes (P<0.01), hypertension (P<0.05) and diet restriction (P<0.05) were found. Controlling for confounding effects of these factors, group distribution to PTCA, compared to CABG, significantly predicted greater improvements in QoL (P<0.01).
