CRAVE

The Coffee and Real-Time Atrial and Ventricular Ectopy (CRAVE) Trial(opens in new window)(link opens in new window)
Gregory M Marcus | UCSF, San Francisco, CA

  • RESULTS: In per-protocol analyses, those who consumed two drinks or more of coffee per day experienced more than a double of PVCs (p=0.007); every additional coffee drink consumed was associated with 12% less SVT episodes (p=0.028), 587 more steps per day, and 18 less minutes of sleep per night. Using genetic analysis, those who metabolize caffeine more quickly experience heightened effect of coffee on PVCs but less effect of coffee on sleep.
