Abstract
Introduction: Coronary artery disease is the largest cause of mortality in the world. The main risk factors for its development include systemic arterial hypertension and type 2 diabetes mellitus. Objective: To search for predictors of the development of plaques and obstructions in coronary arteries and to determine whether the exercise test is a reliable pretest for coronary angiotomography. Methods: 883 computed tomography reports of coronaries were analyzed. Sociodemographic information, health conditions and results of the exercise test from patients were collected, along with calcium score, percentile and number of arterial segments with significant obstruction. The data were analyzed using descriptive and inferential statistics. Significance was considered for p<0.05. Results: It observed that the statistically significant predictors to the calcium score were male, being over 60 years old, having type 2 diabetes mellitus and systemic arterial hypertension. There was no relationship with high BMI and coronary obstruction. Regarding the exercise test, it was possible to observe that the majority of individuals who were positive in the exercise test, did not have a positive calcium score or significant coronary obstructions. Conclusion: The predictors for the development of coronary plaques and obstructions were male, aged ≥60 years, having type 2 diabetes mellitus and systemic arterial hypertension.

Coronary artery disease is the largest cause of mortality in the world
Sample Quantitative, observational and retrospective study, carried out by analyzing 1048 reports of computed tomography (TCcor) exams composed of coronary angiography (CA) and calcium score (CS) of patients referred for Coronary artery disease (CAD) investigation in January 2012 to December 2014 at a reference imaging clinic, located in the city of Maringá - Paraná, this sample being the total number of tests performed in this period
The calcium score and coronary angiography, which make up the TCcor, have been shown to be an ally in the diagnosis and investigation of coronary atherosclerotic diseases, since they are more accurate than other diagnostic methods[8]
Summary
Coronary artery disease is the largest cause of mortality in the world. The main risk factors for its development include systemic arterial hypertension and type 2 diabetes mellitus. Results: It observed that the statistically significant predictors to the calcium score were male, being over 60 years old, having type 2 diabetes mellitus and systemic arterial hypertension. Conclusion: The predictors for the development of coronary plaques and obstructions were male, aged ≥60 years, having type 2 diabetes mellitus and systemic arterial hypertension. The main risk factors for the development of coronary heart disease include age, sex, family history, systemic arterial hypertension (SAH), smoking, dyslipidemia, overweight and type 2 diabetes mellitus (DM2)[3]. This study aimed to detect the predictors for the development of coronary plaques and obstructions detected by computed tomography of coronary arteries, a gold standard exam in the area, in addition to determining if the stress test is a reliable pretest for coronary angiotomography.
