Coffee subtypes associated with reduced CVD, arrhythmias, mortality

According to a study, regular consumption of multiple subtypes of coffee was associated with the prevention of CVD, mortality, and incident arrhythmias.

Peter Kistler, MBBS, PhD, head of clinical electrophysiology research at the Baker Heart and Diabetes Institute and head of electrophysiology at the Alfred Hospital in Melbourne, Australia, told Healio that regular coffee consumption has a beneficial effect on incident arrhythmias, cardiovascular disease, and mortality. “Coffee consumption is associated with cardiovascular benefits, and those with underlying heart rhythm disorders or cardiovascular disease should not empirically discontinue coffee consumption. Physicians should not discourage daily coffee consumption, but rather include it as part of a healthy diet.”

As previously reported by Healio, the primary findings of a large prospective cohort study revealed a significant reduction in the incidence of arrhythmia, cardiovascular disease, stroke, all-cause mortality, and cardiovascular disease mortality among regular coffee drinkers compared to nondrinkers.

In this study, the researchers examined the associations between various coffee subtypes and CVD outcomes. The study included caffeinated (instant, ground) and decaffeinated coffee subtypes. The 449,563 participants (median age, 58 years; 55% female) were categorized according to their daily coffee consumption (0, 1, 1, 2-3, 4-5, and > 5 cups) and followed for 12.5 years.

The primary outcome was the association between coffee subtype consumption and the incidence of arrhythmias, cardiovascular disease, and death. Relationships between coffee subtype consumption and subcategories of arrhythmia (atrial fibrillation/flutter, supraventricular tachycardia, ventricular tachycardia/ventricular fibrillation) and cardiovascular disease (CVD) were secondary outcomes (CHD, congestive cardiac failure, stroke).

The researchers found that drinking up to five cups of ground coffee per day was associated with a lower risk of arrhythmia, cardiovascular disease, and all-cause mortality.
