According to a new study, people with high blood pressure who drink a lot of coffee are more likely to die from heart problems.
But drinking coffee had no effect on people with normal or slightly elevated blood pressure.
Previous research has shown that drinking a cup or two of coffee a day can improve heart health.
Coffee, considered a heart-healthy drink, can be harmful for people with high blood pressure when consumed in moderation.
Two or more cups of coffee a day is linked to a higher risk of death from heart problems in people with very high blood pressure, according to a study published Wednesday in the Journal of the American Heart Association.
Study participants who drank two or more cups of coffee were twice as likely to die from heart problems compared to non-drinkers.
Although excessive coffee consumption was more dangerous for people with severe hypertension or high blood pressure, the same trend was not observed in people with normal or moderate blood pressure. The authors of the study were a group of Japanese researchers who analyzed the health data of 18,609 participants between the ages of 40 and 79.
According to research, drinking any amount of green tea does not affect heart health.
Lead study author Hiroyasu Iso of the American Heart Association said the study is the first to find an association between coffee consumption and death from heart disease in people with very high blood pressure.
Blood pressure is measured by the pressure in the arteries both when the heart is contracting (systolic pressure) and when the heart is resting (diastolic pressure). Hypertension occurs when systolic blood pressure is at least 130 millimeters of mercury (mm Hg) higher than diastolic blood pressure. Art.
The authors of the study defined "very high" blood pressure as at least 160 mmHg. Art. at least 100 mm Hg. Art.
"These findings may support the argument that people with severe hypertension should avoid drinking too much coffee," Iso said in an AHA statement.
The AHA has no official guidelines on how much coffee to drink, with the group saying on its website that one to two cups a day "seems harmless."
Previous research has shown that moderate caffeine intake of one to three cups per day can benefit heart health.
A paper from last year that reviewed three studies, including one that followed 21,000 adults for at least 10 years, found that drinking two cups of coffee a day can reduce the risk of heart failure by 30%. Previous research has also shown that drinking three cups of coffee a day can reduce the risk of heart disease, Insider's Sarah Lindberg.
Drinking coffee has even been shown to prevent premature death: a large study of 171,000 people in the UK published earlier this year found that regular sugar-free coffee drinkers were 16-21% less likely to die than non-drinkers. use caffeine. .
But recent research has shed light on the potential negative effects of coffee. A recent article in the Journal of the American Medical Association found that drinking coffee during pregnancy can affect the growth of the baby.
