Drinking coffee regularly does not cause the heart to beat more, a new study has found.
The findings go against previous studies which suggested that drinking coffee raises the heart rate, and have prompted the research team to call for clinical recommendations against caffeine to be reconsidered.
Past research has indicated that premature atrial contractions (PACs) in the top chambers of the organ and excessive premature ventricular contractions (PVC) at the bottom are linked to a number of different forms of heart disease, and can be caused by caffeine consumption.
To conduct the study published in the ‘Journal of the American Heart’, scientists analysed 1,388 randomly selected participants from the US’ National Heart, Lung and Blood Institute (NHLBI) Cardiovascular Health Study database of nearly 6,000 patients. Those with persistent extra heartbeats were excluded.
