Abstract

Introduction: Coronary Atherosclerosis is the leading cause of death and disability worldwide. Atherosclerosis could be detected noninvasively by coronary calcification, measured by calcium score in CT angiography. Dietary factors are influential in the evolution of coronary plaques, and one of the most prevalent drinks is black tea. We aimed to evaluate the effects of black tea on coronary calcium scores. Methods: This cross-sectional analytical descriptive study was conducted on 200 candidates for CT angiography referred by their physician because their symptoms were suggestive of ischemia. A questionnaire was filled out for every participant, and the habit of tea drinking was asked and marked as none drinker, 1-3 cups per day and >3 cups per day. Results: 89.5% of the participants consumed tea. The mean calcium score in patients who did not drink tea was 674.9±154.74 in those patients who drank 1-3 glasses per day, 269.5±46.9 and in those who drank more than three glasses of tea and was 261.1±45.2. There was a significant statistical relationship between calcium scores and tea intake, independent to other traditional risk factors (P= 0.001). Significant coronary artery plaques were also less prevalent in those who drank tea (36% and 41% in 1-3 and >3 cups, respectively) than non-drinkers (67%). Still, the number of involved vessels was not significantly different. Conclusion: Regular black tea consumption could have protective effects on coronary artery calcification.

经常喝茶与冠状动脉钙化的关系。
简介:冠状动脉粥样硬化是世界范围内导致死亡和残疾的主要原因。动脉粥样硬化可以通过冠状动脉钙化无创检测,通过CT血管造影中的钙评分来测量。饮食因素对冠状动脉斑块的演变有影响,最普遍的饮料之一是红茶。我们的目的是评估红茶对冠状动脉钙评分的影响。方法:本横断面分析描述性研究对200名候选人进行了CT血管造影,他们的医生推荐,因为他们的症状提示缺血。每位参与者都填写了一份调查问卷,并询问了饮茶的习惯,并将其标记为不饮茶、每天1-3杯和每天>3杯。结果:89.5%的参与者喝茶。每日饮茶1-3杯者,不饮茶者的平均钙评分为674.9±154.74,每日饮茶1-3杯者为269.5±46.9,每日饮茶3杯以上者为261.1±45.2。钙评分与茶摄入量之间存在显著的统计学关系,与其他传统危险因素无关(P= 0.001)。与不饮茶的人(67%)相比,喝茶的人(分别为36%和41%,1-3杯和>3杯)的冠状动脉斑块的发生率也较低。然而,受累血管的数量并无显著差异。结论:经常饮用红茶对冠状动脉钙化具有保护作用。
