A new study has found that young adults who have mild cases of hypertension, or high blood pressure levels, have an increased risk of developing heart disease and experiencing heart attacks if they drink coffee.
It’s certainly an unexpected finding as researches usually agree that regular coffee consumption has many health benefits. Previous tests and experiments have shown that the dark liquid improves our performance at work and school, helps overweight and obese people lose more weight, prevents the development of type 2 diabetes, benefits men who have erectile dysfunction (ED), prevents Alzheimer’s disease from setting in, and allows colon cancer patients to live longer.
But Dr. Lucio Mos, lead researcher on the new study and cardiologist from the Hospital of San Daniele del Friuli (Udine, Italy), gave a statement saying that “There is controversy surrounding the long-term cardiovascular and metabolic effects of coffee consumption in patients with hypertension”.
He went on to add the study he and his colleagues conducted was specifically designed to asses whether or not “coffee drinking had an effect on the risk of cardiovascular events, and if the association was mediated by effects on blood pressure and glucose metabolism”.
For the study, the research team looked at 1.201 non-diabetic subjects with the age between 18 and 45. Each of them had stage 1 hypertension, meaning that either their systolic blood pressure was between 140 mm/Hg and 159 mm/Hg or that their diastolic blood pressure was between 90 mm/Hg and 99 mm/Hg, and none of them were receiving any treatment for their condition.
The researchers were interested in examining these subjects’ coffee consumption habits, defined by field experts as the number of cups of caffeinated coffee that someone drinks on a daily basis.
Three (3) main groups could be observed among the subjects – non-drinkers who consumed zero (0) cups of caffeinated coffee on a daily basis, moderate drinkers who consumed somewhere between one (1) and three (3) cups of caffeinated coffee on a daily basis, and heavy drinkers who consumed at least for (4) if not more cups of caffeinated coffee on a daily basis.
Statistically speaking, 26.3 percent (26.3%) of the participating subjects were non-drinkers, 62.7 percent (62.7%) of the participating subjects were moderate drinkers, and 10 percent (10%) of the participating subjects were heavy drinkers.
The research team followed them for an astonishing 12.5 years, frequently comparing and examining the rate that they metabolized caffeinated coffee at, as well as the risk that each subjects had of developing prediabetes. Hypertension patients are notorious for developing type 2 diabetes at a later stage.
What they found was that the risk of developing prediabetes only increased significantly in heavy drinkers with a slow rate of metabolizing caffeinated coffee.
Dr. Mos concluded that those who metabolize caffeinated coffee at a slow rate are exposed longer to the detrimental effects that caffeinated coffee has on glucose metabolism, especially if they are heavy coffee drinkers who are overweight or obese.
The findings were first presented at the Congress of the European Society of Cardiology (ESC).
