Prevalência e fatores de risco na associação entre doença arterial coronariana e aneurisma de aorta

Abstract

Objective: To evaluate coronary artery disease (CAD) prevalence in patients with aortic aneurysm, as well as differences related to aneurysm topographies. To describe the primary risk factors for CAD related to this association and their occasional differences according to AA topographies. Methods:This was an open, prospective, nonrandomized study that evaluated 95 patients (62 men and 33 women, mean age 63 ± 11.8). All patients, asymptomatic for CAD, had undergone aortic CT and coronary angiography. According to the AA topography, they were classified into three groups: 1) Patients with thoracic aortic aneurysm (TAA); 2) thoracoabdominal aortic aneurysm (TAAA); and 3) abdominal aortic aneurysm (AAA). A database was created to store information from clinical data and complementary examinations. Statistical analysis was performed using the Student's t test or analysis of variance (ANOVA) for continuous variables and chi-square test for categorical variables. P values < 0.05 were considered statistically significant.Results: CAD prevalence was 63.1%, and AAA was more prevalent than TAA and TAAA (76% vs. 70% vs. 30%, p = 0.001). The comparative analysis of CAD risk factors based on the aortic aneurysm topography revealed that smoking and dyslipidemia were more prevalent among AAA patients (74.5% vs. 42.3% vs. 60%, p = 0.01 and (54.2% vs. 19.9% vs. 60%, p = 0.007, vessel disease. Conclusion:Asymptomatic CAD is highly prevalent in AA patients, particularly among those with AAA. Study results suggest the need for diagnostic stratification for CAD in patients with AA, especially those with AAA.

Doença arterial coronariana e suporte familiar em idosos

“…A hipertensão arterial é importante condição para a DAC. Estudo sobre a prevalência e fatores de risco na associação entre DAC e aneurisma de aorta refere que, comparando pacientes com e sem DAC, as situações de risco mais frequentes estavam no grupo de pacientes portadores de coronariopatia, entretanto apenas a hipertensão arterial e a dislipidemia foram estatisticamente significantes 25 . Outro fato relevante consiste na não realização de AF pelos idosos entrevistados.…”

Achados incidentais de aneurismas torácicos e abdominais

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] According to the literature, they are most common in the aorta, followed by the iliac arteries and then the splenic artery. 7 They have multifactorial etiology (hereditary, traumatic, infectious, and/or inflammatory), but around 80% of aneurysms are associated with atherosclerotic degeneration of the artery wall.…”

“…2,5 It is estimated that the incidence rate of thoracic aortic aneurysms (TAA) is six cases per 100,000 patients/year, and that the incidence of abdominal aortic aneurysms (AAA) is 25 per 100,000 patients/year. 3,5 Around 10% of patients with AAA have aneurysms in another segment of the aorta, and 25% of patients with TAA also have a concomitant AAA. 3,7 Elective treatment is recommended to repair a TAA if it is symptomatic or reaches 6 cm in diameter.…”

“…3,5 Around 10% of patients with AAA have aneurysms in another segment of the aorta, and 25% of patients with TAA also have a concomitant AAA. 3,7 Elective treatment is recommended to repair a TAA if it is symptomatic or reaches 6 cm in diameter. 1,8,20 As life expectancy has increased, diagnoses of AAA have become more common; within the population over 65 years of age, the rate is as high as 6%, and over 80 years of age it reaches 10%.…”

“…They are often asymptomatic and may be detected incidentally or by screening programs. 3,4,14,15,29 Incidental diagnosis is an unexpected finding in a radiology examination conducted for some other reason and occurs in 5 to 20% of radiological examinations. 30,31 Incidental diagnosis of aneurysms has become more common because of the increase in life expectancy of populations and because of refinements to diagnostic methods and easier access to them.…”
