Drinking two or more cups of coffee a day could put individuals with severely hypertension more prone to suffering a stroke or heart attack. 

The newest study findings showed regular intake of caffeinated coffee in volumes of two or more cups could double the danger of hypertensive patients dying from a heart attack, stroke and other cardiovascular diseases. 

Interestingly, the identical results weren’t found amongst those that drank green tea or simply one cup of coffee every day. 

In response to the researchers behind the study published within the Journal of the American Heart Association Wednesday, their primary goal was to look at the impacts of coffee and green tea consumption on heart problems (CVD) mortality amongst individuals with severe hypertension. 

“Our study aimed to find out whether the known protective effect of coffee also applies to individuals with different degrees of hypertension and likewise examined the consequences of green tea in the identical population,” senior study writer Dr. Hiroyasu said in a news release.

For the study, the team examined data from 18,609 participants aged 40 to 79. The participants were asked to finish a life-style, weight loss plan and medical history questionnaire. Additionally they had health examinations. 

“Heavy coffee consumption was related to an increased risk of CVD mortality amongst individuals with severe hypertension, but not people without hypertension and with grade 1 hypertension. In contrast, green tea consumption was not related to an increased risk of CVD mortality across all categories of blood pressure (BP),” the team wrote of their conclusion. 

Prior research suggested that folks who had a heart attack but drank one cup of caffeinated coffee every day could lower their death risk. This was also believed to assist prevent heart attacks and strokes in healthy adults. Nevertheless, other studies showed that an excessive amount of coffee could increase blood pressure and even cause heart palpitations and anxiety, in accordance with the American Heart Association.
