Hemoglobin A1c as A Potential Indicator for Intraplaque Hemorrhage of Carotid Artery Atherosclerosis in Asymptomatic Adults
Research Square (Research Square)(2021)
摘要
Abstract BackgroundTo investigate the association between hemoglobin A1c (HbA1c) and intraplaque hemorrhage (IPH) in carotid atherosclerotic plaque detected by high-resolution magnetic resonance imaging (HR-MRI) in a community-based population. MethodsIn this cross-sectional, community-based study, a total of 598 participants were recruited from May 2015 to September 2019. All participants underwent carotid artery HR-MRI. Data on demographics, medical history, and physical examinations were obtained through face-to-face interview, and fasting blood sample were collected. HbA1c was determined using high-performance liquid chromatographic analysis. Presence or absence of carotid plaque IPH was determined by HR-MRI. Multiple stepwise logistic regression analysis was performed to investigate the association between HbA1c levels and carotid plaque IPH. ResultsOf the 598 participants, 317 (53.0%) had atherosclerotic plaques, and 25 (4.2%) had IPH in carotid arteries. HbA1c was associated with the presence of IPH (OR, 1.94; 95% CI, 1.38-2.73) in the univariate analysis, and the association remained significant after adjustment for age, sex, traditional vascular factors, high-sensitivity C-reactive protein, and other potential confounders (OR, 1.70; 95% CI, 1.14-2.52).ConclusionsThis study showed that high HbA1c was associated with carotid plaque IPH detected by HR-MRI, which suggests that individuals with high HbA1c may have a higher risk of developing vulnerable carotid plaques.
