Jacob Kelly: AHA Review Highlights Coffee’s Cardiovascular Benefits

Jacob Kelly, Governor of Alaska Chapter at American College of Cardiology, Preventive and Performance Cardiologist at Alaska Heart Institute, shared a post on LinkedIn:

“For twenty years, my patients have asked me the same question: Is my coffee hurting my heart?

I used to say quit, especially if the patient’s heart raced.

This week a new American Heart Association scientific statement confirmed what two decades at the bedside had already taught me: for most people, this advice was wrong.

The practicing-cardiologist, coffee drinking (I’m biased) version of what it says:

Up to 3 to 5 cups a day is safe for most adults and is linked to lower risk of type 2 diabetes mellitus, stroke and atrial fibrillation. A randomized trial tied caffeinated coffee to 39 percent less atrial fibrillation recurrence.
The dose is not linear. Risk for most heart outcomes bottoms out around 3 to 4 cups, then climbs back up. Blood pressure runs the opposite direction.
The source is key. Coffee and tea trend protective. Energy drinks, often stacked with alcohol or stimulants, are where the real harm shows up in our ERs.
It is the kind (of caffeine), the count and the cream. Unfiltered coffee raises LDL, a paper filter fixes it and sugar and syrup erase the benefit.

Some people are genuinely caffeine-sensitive.

If it triggers your rhythm, I’m sorry, pass on the coffee.

Trust yourself.

You probably know best.”
