BACKGROUND: There is still conflicting evidence that green tea may protect against coronary atherosclerosis therefore the present study investigated the association between green tea consumption and arteriographically determined coronary atherosclerosis in a Chinese population. METHODS AND RESULTS: The study population consisted of 520 consecutive patients (379 men and 141 women) who underwent coronary arteriography for the first time. Patients were divided into 2 groups (Non-coronary artery disease [CAD] and CAD groups) according to the results of coronary arteriography. After adjusting the established and potential confounders, green tea consumption was associated with a reduced risk of CAD in male patients, with an adjusted odds ratio (OR) of 0.62 (95% confidence interval, 0.38-1.01) compared with those who did not drink green tea. Compared to non-tea drinkers, the adjusted ORs were 1.09 (0.61-1.96) in male patients consuming less than 125 g of dried green tea leaves per month, 0.36 (0.19-0.71) for 125-249 g per month and 0.36 (0.17-0.73) for > or =250 g per month, with a statistically significant test for trend (P<0.001). Similar dose-response relationships were also observed for frequency, duration, concentration and starting age of green tea drinking in male patients. In female patients, no inverse association was found between green tea consumption and CAD. CONCLUSIONS: Green tea consumption can protect against the development of coronary atherosclerosis in Chinese male patients.
