Consumers who have had heart failure may be able to safely drink coffee again, reports CardioBrief. In a paper published in JAMA Internal Medicine, researchers reported on the short-term electrocardiographic effect of high dose caffeine in more than 50 patients with moderate to severe heart failure. The participants consumed five cups of coffee over 5 hours, during which they underwent electrocardiographic monitoring, the source reports. When the 5 hour period was over, a treadmill test was performed and the researchers found no association between caffeine ingestion and arrhythmic episodes, either during ECG monitoring or the treadmill test.
The authors of the study concluded that there is no solid evidence to support the recommendation to limit moderate caffeine consumption in patients at risk for arrhythmias.
