We assessed the association between tea consumption and acute myocardial infarction (AMI) using INTERHEART China data. Cases (n = 2909) and controls (n = 2947) were randomly selected and frequency matched by age and sex. Participants who drank tea ≥4 cups/d had a significantly higher risk of AMI than tea nondrinkers; odds ratio (OR) was 1.29 (95% confidence interval [CI]: 1.03-1.61) compared with tea nondrinkers. A similar trend was found in green tea drinkers; OR was 1.52 (95% CI: 1.13-2.05) in the participants who drank 3 cups/d and 1.73 (95% CI: 1.35-2.22) in the participants who drank ≥4 cups/d compared with tea nondrinkers. We also found that green tea consumption had a greater effect on females; OR was 2.80 (95% CI: 1.43-5.50) in females. In conclusion, we found that the risk of AMI increases as tea consumption increases. Further studies are needed to confirm this association.
我们利用 INTERHEART 中国数据评估了饮茶与急性心肌梗死（AMI）之间的相关性。通过年龄和性别频数匹配，随机选择病例（n=2909）和对照（n=2947）。与不饮茶者相比，每天饮茶≥4 杯者发生 AMI 的风险显著升高；比值比（OR）为 1.29（95%置信区间[CI]：1.03-1.61）。饮茶者也存在类似的趋势；与不饮茶者相比，每天饮用 3 杯者的 OR 为 1.52（95% CI：1.13-2.05），每天饮用≥4 杯者的 OR 为 1.73（95% CI：1.35-2.22）。我们还发现，绿茶的这种作用在女性中更为显著；与不饮茶者相比，女性中每天饮用 3 杯者的 OR 为 2.80（95% CI：1.43-5.50），每天饮用≥4 杯者的 OR 为 4.25（95% CI：1.90-9.47）。总之，我们发现随着饮茶量的增加，AMI 的发病风险增加。需要进一步的研究来证实这种关联。
