Comparison of the Postprocedural Quality of Life between Coronary Artery Bypass Graft Surgery and Percutaneous Coronary Intervention: A Systematic Review

A summary of the reviewed articles.

Serial number	Author name/date	Summary
1	Zhang et al., 2003 [11]	Quality of life scores were higher in patients opting for CABG at both 6 months and 1 year.
2	Spertus et al., 2005 [12]	1-year quality of life scores were significantly better for patients treated with CABG surgery as opposed to PCI.
3	Borkon et al., 2002 [13]	Patients undergoing CABG achieved greater quality of life at 6 and 12 months after their procedure.
4	Abdallah et al., 2013 [14]	For patients with diabetes and multivessel CAD, CABG surgery provided slightly better quality of life than PCI using drug-eluting stents. The magnitude of benefit was small, without consistent differences, beyond 2 years.
5	Cohen et al., 2011 [15]	Among patients with three-vessel or left main coronary artery disease, scores for quality of life were higher with PCI than with CABG, at 1 month. These differences were no longer apparent at 6 months. At 12 months, the score for quality of life was higher in the CABG group than in the PCI group.
6	van Domburg et al., 2008 [16]	Both stenting and CABG resulted in significant improvement in QOL of patients, up to one year, with CABG patients showing greater improvements.
7	Rumsfeld et al., 2003 [17]	High-risk patients with medically refractory ischemia randomized to PCI versus CABG surgery have equivalent six-month quality of life.
8	Szygula-Jurkiewicz et al., 2005 [18]	There is a significant difference in health-related quality of life, 12 months after percutaneous coronary intervention and coronary artery bypass graft surgery with the difference favoring the patients undergoing bypass.
9	Favarato et al., 2007 [19]	After 1 year of follow-up, the patients submitted to CABG were the ones that presented the greater improvement in QOL.
10	Währborg 1999 [2]	This study has shown that there is no general difference in health-related quality of life 1 year after bypass surgery or angioplasty.
11	Pocock et al., 1996 [20]	Both intervention strategies produce similar benefits for quality of life over several years.
12	Brorsson et al., 2001 [1]	Both bypass surgery and angioplasty lead to improved quality of life for patients with chronic stable angina and one- or two-vessel coronary artery disease. Bypass surgery is associated with better quality of life at 6 months, but by 48 months quality of life is similar for both sets of patients.
13	Serruys et al., 2001 [8]	A significantly better quality of life was reported with stenting, as compared to bypass surgery, after 1 month. No differences were reported between the two groups at 6 months and a slight difference in favor of surgery was found after 12 months.
