Association between carotid intima media thickness and acute ischemic stroke at an Indonesian tertiary referral hospital

Abstract

Objectives: A high prevalence of tobacco smoking contributes to a high incidence of acute ischemic stroke (AIS) in Indonesia. Large-artery atherosclerosis is known to be a significant cause of AIS. The present study was aimed at evaluating the association between AIS and atherosclerosis on the basis of carotid intima-media thickness (CIMT) measurements in a tertiary care hospital in Indonesia. Methods: A total of 79 patients with AIS (case study group) and 79 individuals without AIS (control group) were included. Chi-squared tests and odds ratios were used to compare the groups and determine associations. We also considered factors such as age, body mass index (BMI), sex, type-2 diabetes mellitus (T2DM), hypertension, smoking status, dyslipidemia, socioeconomic status, and educational level in the statistical analyses. A p-value <0.05 was considered statistically significant. Results: Stratification of atherosclerosis into case study and control groups with respect to all study variables indicated a significant relationship (p > 0.05) between atherosclerosis and all variables except low socioeconomic status (p ¼ 0.265) and low educational level (p ¼ 0.180). Regression analysis demonstrated that a BMI 25 kg/m2, compared with a normal BMI, was associated with a 2.139-fold higher risk of atherosclerosis. Conclusions: AIS was associated with atherosclerosis, on the basis of CIMT measurements, according to age, BMI, sex, T2DM, hypertension, smoking status, dyslipidemia, socioeconomic status, and education level in the Indonesian population.
