[Arteriosclerosis obliterans of the lower limbs. Epidemiological study of the risk factors]
Insights
This study found that high cholesterol, high triglycerides, smoking, and hypertension significantly increase the risk of chronic arterial occlusive disease in lower limbs. These factors are crucial for understanding peripheral arterial disease development.
Area of Science:
- Vascular Medicine
- Epidemiology
- Cardiovascular Risk Factors
Context:
- Chronic arterial occlusive disease of lower limbs is a multifactorial condition with debated risk factors.
- Epidemiological studies have yielded conflicting results regarding the role of certain risk factors.
- Understanding these factors is crucial for effective prevention and management strategies.
Purpose:
- To investigate the prevalence of key risk factors in patients with peripheral arterial disease.
- To compare the prevalence of hypercholesterolemia, hypertriglyceridemia, hypertension, smoking, and diabetes in patients versus a control group.
- To determine the relative risk associated with identified risk factors in peripheral arterial disease.
Summary:
- A study of 172 peripheral arterial disease patients and 174 controls identified significant increases in hypercholesterolemia (RR 6.40), hypertriglyceridemia (RR 4.72), smoking (RR 4.03), and hypertension (RR 3.16) among patients.
- Diabetes prevalence was investigated but not found to be statistically significant in this cohort.
- The findings highlight the strong association between lipid profiles, smoking, hypertension, and lower limb arterial disease.
Impact:
- Provides statistically significant data on major risk factors for chronic arterial occlusive disease of lower limbs.
- Informs clinical practice regarding patient risk stratification and targeted interventions for peripheral arterial disease.
- Contributes to the ongoing research on the multifactorial etiology of vascular diseases.
Abstract:
Chronic arterial occlusive disease of lower limbs is recognized as a typical multifactorial disease, but the role of some risk factors is still debated, because contrasting results have been obtained in epidemiological studies. We investigated the prevalence of hypercolesterolemia, hypertriglyceridemia, hypertension, smoking habits and diabetes in a population of 172 patients with peripheral arterial disease admitted to the III and V Medical Division of the "Ospedale Regionale" of Parma in the period January 1979 - April 1983, and in a control group of 174 subjects comparable for age and sex, free of clinical symptoms or signs of atherosclerosis. Statistically significant (p less than 0,005) increases in the prevalence of hypercolesterolemia, hypertriglyceridemia, smoking and hypertension were found in vascular patients compared with controls, the relative risk for the various considered factors being respectively: 6.40; 4.72; 4.03; 3.16.
