LONDON – Drinking more than three cups of coffee daily increased the risk of a cardiovascular event by 50% in a study of more than 1,000 adults aged 45 years or younger with mild, untreated hypertension.
The results of the Hypertension and Ambulatory Recording Venetia Study (HARVEST) also showed that even moderate coffee intake, defined as between one and three cups per day, could up the risk of a cardiovascular event when compared with non–coffee drinkers.
“Don’t drink a lot of coffee; reduce your intake,” Dr. Lucio Mos advised young to middle-aged hypertensive adults in a video interview at the annual congress of the European Society of Cardiology.
Heavy coffee drinking is a strong predictor of increasing blood pressure and rising blood glucose, said Dr. Mos of Hospital San Daniele del Friuli in Udine, Italy. In this study, which had a mean of 12.5 years of follow-up, there was a linear relationship between coffee intake and cardiovascular events such as heart attacks, with the risk increasing with higher coffee intake.
