Clinical Profile and its Associations with Coronary Angiography Results in a Public University Hospital

Abstract

Background: Ischemic heart disease is one of the most common causes of death worldwide. There are few data in the literature about the association of clinical profile and coronary angiography results in the Brazilian population. Objectives: To assess clinical variables and their associations with the results of coronary angiography and to evaluate the safety of coronary angiography in a public university hospital. Methods: From August 2015 to April 2018, 1844 patients submitted to coronary angiography at the Pedro Ernesto University Hospital (HUPE, acronym in Portuguese) were enrolled in this cross-sectional study. They were evaluated by their clinical variables, angiographic results, and procedure complications. Logistic regression was used, and the criterion for determining significance was set at 5%. Results: The median age was 62 years, and most of the population (71%) were outpatients. Stable angina was the most common indication (62.9%). Only 19.7% underwent noninvasive cardiac testing. Arterial hypertension was the most prevalent (88.2%), followed by dyslipidemia (60.2%). Most patients (65%) had obstructive coronary artery disease (CAD). Left main coronary artery (LMCA) stenosis was found in 8.1% of patients. Older age, male sex, quantity of risk factors (RF), and peripheral artery disease were risk predictors for CAD. Death occurred only in 0.16% of the population, and acute coronary artery occlusion in 0.2%. Conclusion: Classic RF showed an association with CAD. The low incidence of complications suggests that coronary angiography is a safe procedure to be conducted in a public university hospital.
