Risk factors for gastrointestinal bleeding after emergency percutaneous coronary intervention

AIM: To identify the risk factors for gastrointestinal bleeding after emergency percutaneous coronary intervention (PCI).

METHODS: Patients who underwent emergency PCI at our hospital from July 2013 to January 2016 were selected, including 56 patients with postoperative gastrointestinal bleeding (hemorrhage group) and 57 patients without (non-hemorrhage group). Univariate and multivariate analyses of relevant clinical variables were then performed to identify risk factors for gastrointestinal bleeding in patients who underwent emergency PCI.

RESULTS: Of 56 patients with gastrointestinal bleeding, 6 had gastric cancer, 17 had peptic ulcer, 7 had gastric lesions, 5 had ischemic bowel disease, 4 had colon cancer, 11 had other disease, and 6 were normal. Univariate analysis showed that patient's age, BMI, smoking, history of digestive disease, hypertension, diabetes, acute coronary syndrome, use of anticoagulants or IIb/IIIa receptor antagonists, thrombocytopenia and decreased hemoglobin were significantly associated with gastrointestinal bleeding after emergency PCI (P < 0.05). Logistic regression analysis showed that age, history of digestive disease, hypertension, acute coronary syndrome, use of IIb/IIIa receptor antagonists, thrombocytopenia and decreased hemoglobin were independent risk factors for gastrointestinal bleeding after emergency PCI (P < 0.05).

CONCLUSION: Age, history of digestive disease, hypertension, acute coronary syndrome, use of IIb/IIIa receptor antagonists, thrombocytopenia and decreased hemoglobin are independent risk factors for gastrointestinal bleeding after emergency PCI.
