RESUMEN
BACKGROUND: Cardiovascular diseases (CVDs) represent important causes of morbidity and mortality. Our study aimed to evaluate cardiovascular risk using the EuroSCORE, ECG and carotid ultrasound for prevention purpose in a population of companions aged 50-70 years, asymptomatic and without CVD. METHODS: History of CVD, risk factors (RF), ECG and carotid ultrasound were evaluated. Intima-media thickness (IMT) was defined as wall thickness >0.9 mm, while focal thickening ≥1.5 mm protruding into the lumen as asymptomatic carotid plaque (ACP). RESULTS: Totally, 1860 subjects were screened. 393 (21.1%) had no RF, 780 (42%) hypertension, 571 (30.7%) hypercholesterolemia, 557 (29.9%) diabetes, 474 (25.5%) smoking, 648 (34.8%) overweight, 300 (16.1%) obesity and 184 (9.9%) metabolic syndrome. Carotid atherosclerosis was detected in 903 (48.5%) subjects, 821 (44.1%) had IMT and 547 (29.4%) ACP, and was significantly related to diabetes, hypertension and hypercholesterolemia. Atrial fibrillation was found in 29 subjects (1.6%) and Brugada pattern in one. Using EuroSCORE, 220 subjects resulted at low (11.8%), 1338 at moderate (71.9%), 292 at high (15.7%) and 10 at very-high risk (0.5%). Adding ACP, the percentages were: low 159 (8.54%), moderate 1020 (54.83%), high 663 (35.64%) and very-high risk 18 (0.96%). CONCLUSIONS: A total of 302 (16.2%) subjects were at least at high risk for CV events according to the EuroSCORE, increasing to 681 (36.61%; P<0.001) adding ACP. The combination of EuroSCORE with ECG may be a useful tool in primary prevention. Carotid ultrasound furtherly increases the power of stratification of asymptomatic patients suitable for pharmacological treatment.
