HealthDay News – According to a study published online Feb. 4 in Stroke, green tea consumption has been linked to improved prognosis in stroke and myocardial infarction (MI) survivors.
Masayuki Teramoto, MD of the Graduate School of Medicine at Osaka University in Japan and colleagues studied the association between green tea and coffee consumption and mortality in 478 stroke survivors, 1,214 MI survivors, and 44,521 people without stroke or MI ages 40 and up 79 years at the start of studies (1988 to 1990).
The researchers documented 9,253 cases of all-cause mortality during the median follow-up of 18.5 years. In stroke survivors, green tea consumption was inversely associated with all-cause mortality (multivariable hazard ratios) [95 percent confidence intervals]: 0.73 [0.42 to 1.27] for one to six cups / week 0.65 [0.36 to 1.15] for one to two cups / day 0.56 [0.34 to 0.92] for three to four cups / day 0.52 [0.31 to 0.86] for five to six cups / day and 0.38 [0.20 to 0.71] for at least seven cups / day compared to non-drinkers). MI survivors had a similar inverse association that was not obvious to those with no history of stroke or MI. In people with no history of stroke or MI, coffee consumption was inversely associated with all-cause mortality. A similar association was seen for MI survivors while no association was seen for stroke survivors.
“Further research is needed to confirm the cardio- and neuroprotective effects of green tea and coffee in survivors of cardiovascular disease,” the authors write.
