Does coffee help or harm your heart?

Drinking coffee does not appear to increase the risk of heart rhythm problems, such as atrial fibrillation, in healthy people. It may temporarily raise blood pressure and the number of non-harmful skipped beats. While it may have other minor mixed positive and negative effects on other heart-related factors and behaviors (such as increased daily step counts, but decreased sleep duration and slightly higher LDL cholesterol), moderate coffee consumption appears to have no impact on the overall risk of cardiovascular disease.
