数据说明

Abstract Background: Patients with coronary artery disease with left ventricular dysfunction present higher mortality and are the major beneficiaries of a myocardial revascularization procedure. A previous study showed that left ventricular ejection fraction (LVEF) is a negative determinant for cardiac catheterization (CAT) after myocardial perfusion scintigraphy (MPS). Objective: To determine clinical and scintigraphic factors associated with cardiac catheterization (CAT) indication in patients undergoing myocardial perfusion SPECT (MPS).Population: Patients consecutively submitted to PMC in the period from March 2008 to December 2012. Methods: All patients undergoing MPS during the study were recorded in a data bank, where epidemiological, clinical and scintigraphic data (perfusion scores and LVEF) were recorded. Patients or their attending physicians were contacted by phone semiannually for follow-up. For statistical analysis, univariate analyzes were performed and variables were selected for inclusion in a logistic regression model. Results: 5536 patients were submitted to MPS, of which 643 performed CAT after the examination. This group presents a higher prevalence of males, hypertensive, dyslipidemic and previously revascularized. Patients undergoing CAT have angina more frequently, more extensive ischemia scores and lower LVEF. Only presence of angina (IC 95% 1.2 - 1.7, p < 0.001) and extent of ischemia (95% CI 1.2 - 1.3, p < 0.001) were independent variables for CAT indication. Conclusion: The presence of angina and the extent of ischemia were the main predictors for CAT post-MPS indication while lower LVEF was not an independent predictor.
