In the largest study to evaluate dietary patterns and quantify cardiac ectopy using 24-hour Holter monitoring, we found no relationship between chronic consumption of caffeinated products and ectopy.Īrrhythmia diet electrophysiology epidemiology. In examining combined dietary intake of coffee, tea, and chocolate as a continuous measure, no relationships were observed after multivariable adjustment: 0.48% fewer PACs/h (95% CI -4.60 to 3.64) and 2.87% fewer PVCs/h (95% CI -8.18 to 2.43) per 1-serving/week increase in consumption. After adjustment for potential confounders, more frequent consumption of these products was not associated with ectopy. There were no differences in the number of PACs or PVCs/h across levels of coffee, tea, and chocolate consumption. The median numbers of PACs and PVCs/h and interquartile ranges were 3 (1-12) and 1 (0-7), respectively. Among 1388 participants (46% male, mean age 72 years), 840 (61%) consumed ≥1 caffeinated product per day. ![]() The main outcomes were PACs/h and PVCs/hour. Frequencies of habitual coffee, tea, and chocolate consumption were assessed using a picture-sort food frequency survey. We studied Cardiovascular Health Study participants with a baseline food frequency assessment, 24-hour ambulatory electrocardiography (Holter) monitoring, and without persistent atrial fibrillation. As certain caffeinated products may have cardiovascular benefits, recommendations against them may be detrimental.
