Positive family history as a risk factor of obliterative atherosclerosis
Insights
A positive family history of peripheral artery disease (PAD) accelerates its development, particularly when combined with other risk factors. However, family history alone or with obesity does not significantly impact PAD progression.
Area of Science:
- Vascular Medicine
- Genetics
- Epidemiology
Background:
- Peripheral artery disease (PAD) is a significant vascular condition.
- Family history is a known risk factor for cardiovascular diseases.
- The specific role of family history in PAD progression requires further elucidation.
Purpose of the Study:
- To investigate the influence of family history on the development of peripheral artery disease.
- To determine the significance of a positive family history in conjunction with other risk factors for PAD.
Main Methods:
- Clinical, angiological, and biochemical examinations of patients with and without PAD.
- Detailed family history recording, including myocardial infarction, cerebral accidents, hypertension, diabetes, and peripheral artery occlusive disease (PAOD) in relatives.
- Statistical analysis of family history in combination with other risk factors.
Main Results:
- A positive family history, defined by conditions like PAOD or early-onset cardiovascular events in relatives, is associated with accelerated PAD.
- Family history plays a significant role only when combined with two or more additional risk factors, notably tobacco smoking.
- Family history in combination with obesity did not show a significant impact on PAD.
Conclusions:
- Positive family history is a contributing factor to PAD development and progression.
- The interplay between genetic predisposition and lifestyle factors like smoking is crucial in PAD.
- Obesity does not appear to modify the impact of family history on PAD.
Abstract:
Clinical, angiological, and biochemical examinations were performed in 981 men and 30 women with organic afflictions of peripheral arteries, and in 411 men and 50 women without any signs of peripheral arterial lesions. Their family histories were thoroughly recorded with particular reference to the occurrence of myocardial infarction, cerebral accidents before and after the age of 60 years, and death of these causes; further, of hypertension, diabetes mellitus, obliterations and gangraenes, in each patient's siblings, parents, and all four grandparents. Furthermore, the significance of positive family history in combination with other risk factors was investigated. Family history can be considered positive with respect to obliterative atherosclerosis when in anyone of the patient's grandparents, parents, or siblings an obliteration of peripheral arteries is present or when anyone of them died of myocardial infarction or apoplexy, especially when aged under 60 years. Presence of several factors in the specified next of kin accelerates the obliterative process in the patient. A positive family history, however, plays no decisive role either alone or in combination with any other single risk factor, but only in combination with two or more other factors, one of which is always tobacco smoking; it is not significant in any combination with obesity.
