The stroke rate of middle-aged and elderly people who drink coffee in the morning is greatly increased.
After getting up, would you like a cup of coffee to refresh your mind? Middle-aged and elderly people who drink little coffee may have a heart attack if they wake up with a cup of coffee in the morning if they have a risk factor for heart disease, Taiwan's United Daily News reported.
Anna, professor at Brown University? In a study published in the journal Epidemiology, Beilin said that middle-aged and elderly people who drank little coffee had a significantly higher risk of stroke an hour after drinking coffee in the morning, and that there were more than three risk factors for heart disease, such as diabetes, high blood pressure, smoking, and people who did little exercise.
However, people who drank more than four cups of coffee a day did not increase their risk of heart disease. Beilin's team believes that heavy coffee drinkers may be accustomed to caffeine, so their cardiovascular system is not affected.
The study involved 503 Costa Ricans who had their first stroke between 1994 and 1998. The subjects' coffee consumption and overall diet hours and days before stroke, as well as medical history, lifestyle and background, were included in the study.
People who drank an average of less than one cup of coffee a day were four times as likely to have a heart attack an hour after drinking it in the morning. Drinking two or three cups a day increases your chances by 60%. There is no difference between people who drink more than four drinks.
The team believes that the stimulating effect of caffeine may promote nervous system activity, causing fat deposited in the walls of arteries to fall off, blocking blood flow to the heart and causing heart disease.
Beilin said that for people who have risk factors for heart disease and do not drink much coffee, morning coffee may be the "last straw" and this group had better consider giving up drinking coffee.
