“But our study shows that regular coffee intake is safe and could be part of a healthy diet for people with heart disease.”ĭr. “Clinicians generally have some apprehension about people with known cardiovascular disease or arrhythmias continuing to drink coffee, so they often err on the side of caution and advise them to stop drinking it altogether due to fears that it may trigger dangerous heart rhythms,” Kistler said in the statement. Of the adults with arrhythmia, coffee intake – especially of one cup per day – was associated with a lesser risk of premature death.Ī fan of black coffee and dark chocolate? It's in your genes, a new study says For people with cardiovascular disease, no level of coffee intake was found to be linked with developing arrhythmia. Participants analyzed in a third study were those who already had arrhythmia or a type of cardiovascular disease. Drinking two to three cups of any type of coffee every day was associated with a lower risk of dying early or from heart disease. “I suppose there may have been a perception that less expensive ‘instant’ coffee may be less beneficial than ‘ground’ coffee which might be seen as ‘purer,’ but this was not the case in our study,” he added.ĭrinking one to five cups of ground or instant coffee a day was linked with lower risks of having arrhythmia, heart disease or failure, or stroke. Whether the decaf coffee was ground or instant wasn’t specified, Kistler said via email. People who drank roughly one cup of coffee per day had the lowest risk of having stroke or dying from cardiovascular disease.Īnother study looked into the relationships between different types of coffee – caffeinated ground, caffeinated instant and decaffeinated – and the same health outcomes. Participants who drank two to three cups of coffee daily had the lowest risk for later developing the heart problems the study focused on, the researchers found. The first study focused on more than 382,500 adults who didn’t have heart disease and were age 57 on average. The authors of the current research wanted to examine the relationship between coffee drinking and heart rhythm problems (arrhythmias) cardiovascular disease, including coronary heart disease, heart failure and stroke and total and heart-related deaths among people with and without heart disease. When joining the registry, participants reported where their coffee consumption fell on a range from up to a cup to six cups or more daily. “We found coffee drinking had either a neutral effect – meaning that it did no harm – or was associated with benefits to heart health,” said Kistler, a leading arrhythmia expert who is also a professor of medicine at both the University of Melbourne and Monash University.įor all the studies, Kistler and the other researchers used data from UK Biobank, which follows the health outcomes of more than 500,000 people for at least 10 years.
