|Benefits of coffee for the heart|
A new study presented at the 71st Annual Scientific Session of the American College of Cardiology reveals the benefits of coffee for the heart. Coffee consumption, especially two to three cups daily is associated with a lower risk of heart disease and a longer life. The new analysis refutes the long-held assumption that coffee can be bad for the heart. This research provides assurance that coffee is not linked to heart disease and may actually protect the heart. "Because coffee can speed up the heart rate, some people worry that drinking it may trigger or worsen certain heart problems.
This is where the general medical advice to stop drinking coffee may come from. But our data suggest that daily coffee intake should not be reduced, but rather included as a part of a healthy diet for people with and without heart disease," said Peter M. Kistler, MD in his presentation. Peter M. Kistler, MD is professor and head of arrhythmia research at Alfred Hospital and Baker Heart Institute in Melbourne, Australia. "We found that drinking coffee had a neutral effect, meaning it did not harm—or was associated with benefits for heart health," Kistler continued. Kistler and his team used data from the UK BioBank, a large, prospective database with health information from more than half a million people followed for at least 10 years.
The researchers looked at varying levels of coffee consumption from one cup to more than six cups a day and their association with heart rhythm problems (arrhythmias), cardiovascular disease, including coronary artery disease, heart failure and stroke.
Patients were grouped according to how much coffee they drank each day. Coffee consumption was assessed from a questionnaire filled out after entry into the registry. Overall, they found no effect or, in most cases, a significant reduction in cardiovascular risk after controlling for exercise, alcohol, smoking, diabetes, and high blood pressure, which may also play a role in heart health and prolonging life.
For the first study, researchers examined data from 382,535 people without known heart disease to see if coffee drinking played a role in the development of heart disease or stroke during 10 years of follow-up. The average age of the participants was 57 years and half were women. In general, drinking two to three cups of coffee a day was associated with the greatest benefits. Which means a 10-15 percent lower risk of coronary heart disease, heart failure, heart rhythm problems, or death for any reason.
The risk of stroke or heart-related death was lowest among people who drank one cup of coffee a day. The researchers did observe an association with coffee intake and heart rhythm problems. Maximum benefit was seen among people who drank two to three cups of coffee a day with less benefit seen among those who drank more or less. The second study involved 34,279 people who had some form of cardiovascular disease at baseline.
Intake of two to three cups of coffee a day was associated with a lower chance of death compared to not drinking coffee. Importantly, consuming any amount of coffee was not associated with a higher risk of heart rhythm problems. This includes atrial fibrillation (AFib) or atrial flutter, which Kistler says is often a concern for doctors. Of the 24,111 people included in the analysis who had an arrhythmia at baseline, drinking coffee was associated with a lower risk of death. For example, people with AFib who drank one cup of coffee a day were nearly 20 percent less likely to die than non-coffee drinkers. Although two to three cups of coffee a day seems to be the most preferred overall, Kistler says that people shouldn't increase their coffee intake, especially if it makes them feel anxious or uncomfortable.
"There are a wide variety of mechanisms by which coffee can reduce mortality and have a beneficial effect on cardiovascular disease," he said. “Coffee drinkers should feel reassured that they can continue to enjoy coffee even if they have heart disease. Coffee is the most common cognitive enhancer, it wakes you up, makes you mentally sharper and it is a very important component of many daily lives. person."
