Daily coffee may benefit heart, claims study
Washington, March 24: Drinking two to three cups of coffee a day is associated with the greatest heart benefits, according to a recent study.
The research presented at the American College of Cardiology's 71st Annual Scientific Session says that these trends held true for both people with and without cardiovascular disease. Researchers said the analyses -- the largest to look at coffee's potential role in heart disease and death -- provide reassurance that coffee isn't tied to new or worsening heart disease and may actually be heart protective.

"Because coffee can quicken heart rate, some people worry that drinking it could trigger or worsen certain heart issues. This is where general medical advice to stop drinking coffee may come from. But our data suggest that daily coffee intake shouldn't be discouraged, but rather included as a part of a healthy diet for people with and without heart disease," said Peter M Kistler, MD, professor and head of arrhythmia research at the Alfred Hospital and Baker Heart Institute in Melbourne, Australia, and the study's senior author.
"We found coffee drinking had either a neutral effect -- meaning that it did no harm -- or was associated with benefits to heart health," he added.
Kistler and his team used data from the UK BioBank, a large-scale prospective database with health information from over half a million people who were followed for at least 10 years.
Researchers looked at varying levels of coffee consumption ranging from up to a cup to more than six cups a day and the relationship with heart rhythm problems (arrhythmias); cardiovascular disease, including coronary artery disease, heart failure and stroke; and total and heart-related deaths among people both with and without cardiovascular disease.
Patients were grouped by how much coffee they reported drinking each day. Overall, they either found no effect or, in many cases, significant reductions in cardiovascular risk after controlling for exercise, alcohol, smoking, diabetes and high blood pressure that could also play a role in heart health and longevity.
