Gordura visceral e fatores de risco cardiovascular na síndrome coronariana aguda

Abstract

Introduction: The visceral fat (VF) is associated with cardiovascular risk factors but their relationship with the various risk factors in acute coronary syndrome (ACS) has not been sufficiently studied in the Brazilian population. Objective: The aim of this study was to quantify the VF by ultrasonography in patients with ACS and correlated to measurements at other variables linked to increased risk of cardiovascular ischemic events. Methods: A cross-sectional study with 43 subjects presenting with ACS was performed (69,7% men). The mean age was 58.7 ± 19 (30-75 years). The quantification of abdominal visceral adipose tissue was made using ultrasonography with a 3.5 MHz linear transducer. The thickness of visceral fat was measured between the inner face of the abdominal musculature and the posterior surface of the abdominal aorta, above 1 cm umbilicus. The tests were performed by the same examiner. The thickness of VF was correlated with waist circumference, blood pressure and metabolic risk factors. Results: There was a positive correlation of VF with LDL-C, waist circumference and a negative correlation with serum creatinine. VF thickness was higher in AI (7.6 ± 1.5 cm). In the SST and SSST group it was 6.6 ± 3.2 cm and 5.8 ± 2.4 cm, respectively. The left ventricular ejection fraction (LVEF) was lower in the SSST group. The presence of obesity (4) and smoking (5) was higher in the AMI group with SST. Conclusion: Correlations of VF by ultrasound with some risk factors well established can also be seen in patients with ACS, which reinforces the prognostic significance and the importance of their determination to prescription and guidance of prophylactic measures.
