Abstract:
Objective: To explore the relationship between lower extremity atherosclerosis disease (LEAD) and cardiovascular risk factors in elder people.
Methods: A total of 700 consecutive patients receive lower extremity Color Doppler ultrasound in our hospital from 2013-05 to 2014-11 were investigated. The patients were divided into 3 age groups: Young and middle group, n=83, Elder group, n=377 and Senile group, n=240. Based on ultrasound scoring system, the patients were divided into 4 groups: Normal group, n=112, Mild atherosclerosis (Mild) group, n=81, Moderate group, n=466 and Severe group, n=41. The cardiovascular risk factors among different groups were compared.
Results: Multivariate unconditional logistic regression analysis showed that age, smoking, history of diabetes, uric acid (UA), ankle-brachial index (ABI) were the independent risk factors for LEAD (B=0.144, 1.496, 0.963, 0.004, -2.510; 95% CI: 1.120-1.190, 2.257-8.824, 1.456-4.716, 1.001-1.007, 0.012-0.534;P=0.000, 0.000, 0.001, 0.006, 0.009 respectively. Ordinal logistic regression analysis indicated that age, male gender, smoking, ABI, UA, history of hypertension were related to the severity of atherosclerosis (B=0.130, 0.737, 0.592, -3.365, 0.003, 0.735; 95% CI: 0.097-0.162, 0.222-1.252, 0.052-1.132, -4.674 to -2.055, 0.001-0.005, 0.313-1.157;P=0.000, 0.005, 0.032, 0.000, 0.005, 0.001 respectively. Compared with Young and Middle groups, Elder and Senile groups had increased rates of moderate and severe arteriosclerotic lesions; compared with Elder group, Senile group presented the higher incidence of moderate and severe lesions, allP<0.01. With elevated age, the severity score of LEAD increased accordingly,P<0.01.
Conclusion: Lower extremity atherosclerosis lesions were more severe in elder patient, and it was particularly severe in senile patients.
