Data extraction and synthesis: The literature review, data extraction, and quality evaluation were conducted by two independent researchers, and the meta-analysis was performed using RevMan 5.4 software.Main outcomesThe main outcome was that MACE occurred during the follow-up period.ResultsA total of 40 articles were included. The meta-analysis erevealed that dyslipidemia (OR = 1.50; 95% CI [1.19, 1.89], p = 0.0007), diabetes mellitus (OR = 1.70; 95% CI [1.43, 2.02], p < 0.00001), hypertension (OR = 1.62; 95% CI [1.35, 1.96], p < 0.0001), history of smoking (OR = 2.08; 95% CI [1.51, 2.85], p < 0.0001), poorer ventricular function (OR = 2.39; 95% CI [2.17–2.64], p < 0.0001), impaired left ventricular ejection fraction (LVEF) (OR = 1.86; 95% CI [1.71–2.03], p < 0.0001), door to balloon (D-to-B) time (OR = 0.61; 95% CI [0.42–0.88]; p = 0.009), thrombolysis in myocardial infarction (TIMI) (OR = 1.41; 95% CI [1.17, 1.70], p = 0.0004), renal dysfunction (OR = 1.82; 95% CI [1.37, 2.43], p < 0.0001), and multi-vessel coronary artery disease (OR = 0.41; 95% CI [0.37, 0.46], p < 0.0001) were significantly associated with MACE after PCI.ConclusionThe independent risk factors of MACE after PCI are dyslipidemia, hypertension, diabetes mellitus, smoking history, Killip class > II, LVEF ≤40%, D-to-B time >90 min, TIMI flow grade ≤ II, renal insufficiency, and multivessel disease.
