Abstract

BACKGROUND: Atherosclerosis is the major etiopathogenic factor that decides cardiovascular mortality and morbidity. While inflammation is the putative mechanism for atherosclerosis in various experimental studies, chronic inflammatory state (e.g. in rheumatoid arthritis [RA]) is often neglected as a contributing factor for the development of atherosclerosis. RA patients have two to four times more risk of fatal or non-fatal cardiovascular events, which is not explained by traditional risk factors alone. For example, low-density lipoprotein (LDL) cholesterol levels may not convey the true atherosclerotic risk in RA patients - "the lipid paradox". Thus, for better risk stratification of future cardiovascular events in RA, the traditional parameters like diabetes, hypertension, and dyslipidemia may not suffice. Newer parameters like carotid intimal-medial thickness (CIMT), coronary calcification scores, and C-reactive protein (CRP) may be needed. This study determined subclinical atherosclerotic load in groups of RA and non-RA patients with comparable Framingham risk scores using CIMT values. MATERIALS AND METHODS: In this hospital-based cross-sectional study, the RA study group had 64 patients with RA (disease duration > 1 year) and 64 controls were patients with at least one traditional risk factor of cardiovascular disease (e.g., hypertension, cigarette smoking, dyslipidemia, and diabetes mellitus). They were all analyzed for CIMT. The aim was to compare if there was a difference in CIMT scores between groups of RA and non-RA patients, with comparable Framingham score cardiovascular risk categories. RESULTS: CIMT was significantly higher in the study population compared to controls, indicating increased subclinical atherosclerotic load in the former. Mean CIMT was higher in all age groups in RA patients when compared to the control population (statistically significant in age groups 40-49 years 0.66 ± 0.07 mm vs 0.64 ± 0.06 mm, P < 0.026 and 50-59 years 0.8 ± 0.05 mm vs 0.76 ± 0.05 mm, P < 0.047). CIMT was significantly higher in the intermediate-risk groups (based on the Framingham risk score) in the RA study population when compared with the same risk categories of the control population. Atherogenic indices such as LDL/high-density lipoprotein (HDL) ratio, atherogenic index, and CIMT were significantly higher in the RA patients with more than five years of disease duration than those with a duration of fewer than five years. CONCLUSION: Subclinical atherosclerotic load is higher in RA versus controls. The mean CIMT was higher in all age groups in RA compared to the controls. CIMT was significantly higher in the intermediate-risk subgroup (by Framingham risk score) when compared between RA and controls. RA subgroup comparisons based on seropositivity/seronegativity, high/normal CRP, and disease activity (low, intermediate, and high) for CIMT were not found to have statistically significant differences. RA group had lower HDL cholesterol and comparable LDL cholesterol values compared to controls.

摘要

背景:动脉粥样硬化是决定心血管疾病死亡率和发病率的主要病因。虽然炎症在各种实验研究中被认为是动脉粥样硬化的机制,但慢性炎症状态(如类风湿关节炎[RA])往往被忽视,而它是动脉粥样硬化发展的一个促成因素。RA患者发生致命或非致命心血管事件的风险是常人的两到四倍,这无法仅用传统风险因素来解释。例如,低密度脂蛋白(LDL)胆固醇水平可能无法反映RA患者真正的动脉粥样硬化风险——“脂质悖论”。因此,为了更好地对RA患者未来心血管事件进行风险分层,仅靠糖尿病、高血压和血脂异常等传统参数可能不够。可能需要诸如颈动脉内膜中层厚度(CIMT)、冠状动脉钙化评分和C反应蛋白(CRP)等新参数。本研究使用CIMT值确定了具有可比弗雷明汉风险评分的RA患者组和非RA患者组的亚临床动脉粥样硬化负荷。 材料与方法:在这项基于医院的横断面研究中,RA研究组有64例RA患者(病程>1年),64名对照为至少有一项心血管疾病传统风险因素(如高血压、吸烟、血脂异常和糖尿病)的患者。对他们都进行了CIMT分析。目的是比较具有可比弗雷明汉评分心血管风险类别的RA患者组和非RA患者组之间CIMT评分是否存在差异。 结果:与对照组相比,研究人群的CIMT显著更高,表明前者的亚临床动脉粥样硬化负荷增加。与对照组相比,RA患者所有年龄组的平均CIMT更高(40 - 49岁年龄组有统计学意义,分别为0.66±0.07毫米和0.64±0.06毫米,P<0.026;50 - 59岁年龄组分别为0.8±0.05毫米和0.76±0.05毫米,P<0.047)。与对照组相同风险类别相比,RA研究人群中中度风险组(基于弗雷明汉风险评分)的CIMT显著更高。病程超过五年的RA患者的致动脉粥样硬化指数,如LDL/高密度脂蛋白(HDL)比值、致动脉粥样硬化指数和CIMT,显著高于病程少于五年的患者。 结论:RA患者的亚临床动脉粥样硬化负荷高于对照组。与对照组相比,RA患者所有年龄组的平均CIMT更高。在RA组和对照组之间比较时,中度风险亚组(按弗雷明汉风险评分)的CIMT显著更高。基于血清阳性/血清阴性、CRP高/正常以及疾病活动度(低、中、高)对RA亚组进行CIMT比较,未发现有统计学显著差异。与对照组相比,RA组的HDL胆固醇较低,LDL胆固醇值相当。
