Design and Outcomes of the Studies Included in the Meta‐Analysis

Author/Year	Design	Total Patients, No.	Follow‐Up	Primary Outcomes	MACE Definition
Yang 201114	Single center, retrospective	136	2 y	Cardiac mortality and occurrence of MACE	Cardiac death, recurrent myocardial infarction, repeat revascularization (PCI and/or CABG), and heart failure rehospitalization
Shi 201415	Single center, retrospective	148	3 y	Survival and occurrence of MACE	Cardiac death, recurrent myocardial infarction, repeat revascularization (PCI and/or CABG), and rehospitalization because of heart failure
Valenti 201416	Multicenter registry, retrospective	169	1 y	1‐ and 3‐y cardiac survival	Not reported
Watanabe 201617	Multicenter registry, retrospective	121	4 y	All‐cause death	Not reported
Deng 201718	Single center, retrospective	377	1 y	Composite of all‐cause death, nonfatal myocardial infarction, ischemia‐driven coronary revascularization, and hospitalization for heart failure at 1 y	All‐cause death, nonfatal myocardial infarction, ischemia‐driven coronary revascularization, and hospitalization for heart failure
Henriques 201610	Multicenter RCT	302	4 mo	LVEF and LVEDV, assessed by cardiac MRI at 4 mo	Cardiac death, myocardial infarction, and CABG

CABG indicates coronary artery bypass grafting; LVEDV, left ventricular end‐diastolic volume; LVEF, left ventricular ejection fraction; MACE, major adverse cardiovascular events; MRI, magnetic resonance imaging; PCI, percutaneous coronary intervention; RCT, randomized controlled trials.
