Cigarette smoking is correlated with the periventricular hyperintensity grade of brain magnetic resonance imaging
Abstract
A new studies have observed a significant inverse correlation between cigarette smoking or lipid abnormalities and periventricular hyperintensities (PVHs) on T2-weighted magnetic resonance imaging (MRI) scans of the brain, which is surprising because smoking and hyperlipidemia are considered risk factors for cerebrovascular disease. We investigated the relation between smoking and lipid abnormalities and PVHs on T2-weighted MRIs. MRI scans were performed in 253 patients over the age of 40 years, and PVHs were assessed retrospectively by use of a five-point scale. Patients who were receiving medical treatment for hyperlipidemia were excluded. Serum levels of total cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides were determined in the fasting state by an automated enzymatic procedure. The low-density lipoprotein (LDL) cholesterol level was calculated by use of Friedewald's equation. Age, sex, hypertensive status, antihypertensive treatment, presence or absence of diabetes mellitus, and history of stroke were included in the analysis. Multiple linear regression analysis showed that age, hypertension, smoking, and antihypertensive treatment were significantly and independently correlated with the PVH scor...Continue Reading
