'Coffee Cuts Risk of Death and Cardiovascular Disease'


The impact of coffee subtypes on incident cardiovascular disease, arrhythmias, and mortality: long-term outcomes from the UK Biobank

From the European Journal of Preventive Cardiology, zwac189, https://doi.org/10.1093/eurjpc/zwac189

Abstract

Aims


Epidemiological studies report the beneficial effects of habitual coffee consumption on incident arrhythmia, cardiovascular disease (CVD), and mortality. However, the impact of different coffee preparations on cardiovascular outcomes and survival is largely unknown. The aim of this study was to evaluate associations between coffee subtypes on incident outcomes, utilizing the UK Biobank.

Methods and results

Coffee subtypes were defined as decaffeinated, ground, and instant, then divided into 0, <1, 1, 2–3, 4–5, and >5 cups/day, and compared with non-drinkers. Cardiovascular disease included coronary heart disease, cardiac failure, and ischaemic stroke. Cox regression modelling with hazard ratios (HRs) assessed associations with incident arrhythmia, CVD, and mortality. Outcomes were determined through ICD codes and death records. A total of 449 563 participants (median 58 years, 55.3% females) were followed over 12.5 ± 0.7 years. Ground and instant coffee consumption was associated with a significant reduction in arrhythmia at 1–5 cups/day but not for decaffeinated coffee. The lowest risk was 4–5 cups/day for ground coffee [HR 0.83, confidence interval (CI) 0.76–0.91, P < 0.0001] and 2–3 cups/day for instant coffee (HR 0.88, CI 0.85–0.92, P < 0.0001). All coffee subtypes were associated with a reduction in incident CVD (the lowest risk was 2–3 cups/day for decaffeinated, P = 0.0093; ground, P < 0.0001; and instant coffee, P < 0.0001) vs. non-drinkers. All-cause mortality was significantly reduced for all coffee subtypes, with the greatest risk reduction seen with 2–3 cups/day for decaffeinated (HR 0.86, CI 0.81–0.91, P < 0.0001); ground (HR 0.73, CI 0.69–0.78, P < 0.0001); and instant coffee (HR 0.89, CI 0.86–0.93, P < 0.0001).

Conclusion

Decaffeinated, ground, and instant coffee, particularly at 2–3 cups/day, were associated with significant reductions in incident CVD and mortality. Ground and instant but not decaffeinated coffee was associated with reduced arrhythmia.

...good news, but I don't like coffee.

happyone said...

I don't drink any kind of coffee. Love the smell but just don't like it.

Looks like you have to drink both caffeinated and decaffeinated. A little confusing! Usually with these things you have to drink or eat a truckload of them to have them make any difference or have any effect. Everything in moderation!

Lee said...

Whoohoo! I've just taken the last mouthful of my morning mug of coffee...I only ever have one coffee a day.

these studies are so interesting, and they always seem to come to different conclusions over the years. my husband has been a heart patient for many years now and we were always told little to no caffeine per day so now they are saying it's ok haha
always interesting reading though

Magaly Guerrero said...

Thank goodness for that! Because I would hate to have to give up my decaf.

Margaret D said...

Coffee and walnut cake is one of my favourites, and I love coffee creams, but I just don't like the drink, funny isn't it.

Hello,

Take care, enjoy your day and happy weekend!

linda said...

That's good to know I do like a cup of coffee.

Rain said...

I'd read about the benefits of drinking coffee, I'm happy to know decaf is still good for you too. I switched to decaf many years ago and found my anxiety reduced nearly 100%!

Bob Bushell said...

I love coffee, thanks Jan.

Hootin Anni said...

With my SVT history, No caffeine for me.

Salty Pumpkin Studio said...

Interesting results. I changed to regular coffee when out and about, and sometimes at home between decaf.

I gave up coffee years ago, probably at the time we were told it wasn't good for us.

I am not a coffee drinker myself

DUTA said...

I believe it's true. I do like to drink coffee, not the black type but the instant one.
