According to recent statistics from the American Heart Association and published in the Daily Coffee News, drinking two or more cups of coffee each day may raise the risk of cardiovascular disease.
Even among people with the highest blood pressure (“severe hypertension”), researchers discovered that drinking even one cup of coffee was not connected with an elevated risk of cardiovascular disease. According to a study published in the Journal of the American Heart Association, drinking up to one cup of coffee or green tea daily did not increase the chance of developing this condition.
“These findings may support the concept that individuals with severe high blood pressure should avoid drinking large amounts of coffee,” says the study’s lead author, Hiroyasu Iso, MD, Ph.D., MPH. Dr. Iso is the head of the Institute for Global Health Policy Research at the National Center for Global Health and Medicine in Tokyo.
“To the best of our knowledge, this is the first study to show a link between drinking two or more cups of coffee per day and the risk of mortality from cardiovascular disease in those with severe hypertension,” according to Iso.
This study adds to the growing body of data that coffee’s antioxidants and anti-inflammatory properties may improve heart health and life expectancy. Still, it does so with extreme care for patients with high blood pressure.
The latest Japanese study comprised approximately 6,750 men and 12,000 women from the long-running Japan Collaborative Cohort Study for Cancer Risk Evaluation. Those with a systolic blood pressure of 160 or above had an increased risk of cardiovascular disease.
Although the American Heart Association considers systolic blood pressure readings between 140 and 159 “high blood pressure,” this sample did not show an increased risk of cardiovascular disease.
Hiroyasu Iso, a heart health expert, and senior author says the findings “may confirm the concept that individuals with severe high blood pressure should avoid drinking excessive coffee.” Caffeine consumption may have more hazards than benefits for persons with severe hypertension. It’s worth noting that green tea consumers with various systolic blood pressures all had a lower risk of cardiovascular disease.
Drinking coffee daily may help prevent heart attacks and strokes in healthy individuals and lessen the chance of mortality in people who have previously suffered a heart attack, according to a study published by the American Heart Association.
According to the American Heart Association, hypertension (also known as high blood pressure) develops when the force of blood pressing against the walls of blood arteries is regularly too high, increasing the heart’s workload.
Blood pressure is typically measured in millimeters of mercury (mmHg). Blood pressure readings are displayed as both systolic (highest) and diastolic (lowest) values (diastolic).
The American Heart Association and the American College of Cardiology have issued new recommendations defining hypertension as more than 130 mm Hg blood pressure. In the United States, hypertension (high blood pressure) is considered severe at 140/90 mm Hg and life-threatening at 180/120 mm Hg.
