Factors of carotid arterial enlargement in a population aged 59 to 71 years: the EVA study
Abstract
Factors of carotid arterial enlargement are not well known in general populations. The purpose of this study was to assess the cross-sectional associations of arterial wall lesions and cardiovascular risk factors with carotid lumen diameter in elderly subjects. B-mode ultrasound examinations of the carotid arteries and risk factor assessment were made in 1272 participants in the EVA (Etude sur le vieillissement artériel) Study, a longitudinal study designed to evaluate vascular and cognitive aging in men and women aged 59 to 71 years. Ultrasound examinations included measurements of intima-media thickness (IMT) and interadventitial and lumen diameters of the common carotid arteries and quantification of atherosclerotic plaques in extracranial carotid arteries. Men showed greater IMT interadventitial and lumen diameters of the common carotid arteries than did women. In both sexes, common IMT and plaque score were positively associated with common interadventitial and lumen diameters. Stepwise multiple regression analysis showed that male sex, body height and weight, common IMT, plaque score, systolic blood pressure, and alcohol consumption were positively and independently related to lumen diameter. On the other hand, an indepen...Continue Reading

ApoE, Lipids & Cholesterol
Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases.

Cardiomegaly
Cardiomegaly, known as an enlarged heart, is a multifactorial disease with different pathophysiological mechanisms. Hypertension, pregnancy, exercise-induced and idiopathic causes are some mechanisms of cardiomegaly. Discover the latest research of cardiomegaly here.
