Angiotomografia das artérias coronárias: a exequibilidade de sua implementação em capital da região Nordeste

Abstract

Background: Cardiovascular diseases are the main cause of global mortality. Coronary Artery Angiography (ATCC) is a noninvasive method of high accuracy in the diagnosis and stratification of coronary artery disease (CAD) risk. However, it is not known how feasible its implementation in a city in the Northeast region. Objective: To evaluate the feasibility of implementing the ATCC in Northeastern capital. Methods: Observational, transversal and analytical study with 1293 patients submitted to ATCC. The characteristics of the patients, the indication of the exams and their results collected in the Northeastern capital were compared with a sample of exams previously performed at the Dante Pazanesse Institute of Cardiology (IDPC). The quantitative variables were compared by the Variance Analysis Test and the categorical variables by the Pearson Chi-Square. Results: It was observed that in the older services the mean age was higher (59 ± 11 years). Males predominated only in IDPC (n = 209, 54%). Risk factors such as systemic arterial hypertension (SAH) and dyslipidemia presented heterogeneous distribution. Indicator criteria - positive ischemic evidence and presence of symptoms - were the most prevalent (p <0.001). The frequency of normal ATCC ranged from 40.8 to 48.3% (p = 0.24) and the degree of calcification of coronary artery was similar among groups (p = 0.15). Conclusion: The frequency of normal tests was similar between services. Presence of symptoms and positive ischemic evidence were the most prevalent indications. The implementation of the ATCC in northeastern capital proved feasible, thus benefiting this population.
