Abstract

Objective This study aimed to investigate the incidence and related risk factors of cerebral microbleeds (CMBs) in young and middle-aged patients with hypertension. Methods The study included 232 young and middle-aged (18-59 years-old) patients with hypertension from September 2014 to December 2016 in the Department of Neurology, Affiliated Hospital of Guizhou Medical University, China. The data were recorded which included demographics, vascular risk factors, medication history, and imaging data of patients. CMBs were evaluated based on the microbleeds anatomical rating scale. Results Of the enrolled participants, 115 were CMB positive, accounting for 49.6%. CMBs were more prone to occur in deep regions than in others (39.13%). Multiple cerebral microbleeds were associated with white matter hyperintensities(WMH), dyslipidemia, hyperhomocysteine, and uric acid. Moreover, WMH, dyslipidemia, ever smoker, antiplatelets use, and hyperhomocysteine were found to be risk factors for deep or infratentorial CMBs in young and middle-aged patients with hypertension. However, the lobar CMBs only had an independent correlation with dyslipidemia in these participants. Conclusions The incidence of CMBs in patients with hypertension was relatively high. It mostly occurred in a deep or infratentorial area with more vascular-associated risk factors. However, in patients with lobar CMBs, factors associated with lipid metabolism, such as amyloid deposition and unidentified genotype variation, may be crucial. Screening and regular follow-ups of CMBs by Susceptibility Weighted Imaging and active prevention in young and middle-aged patients with hypertension have clinical significance for timely understanding and predicting the occurrence and development of related cerebrovascular disease events.
