And we're talking European-style coffee

"In this large, observational study, ground, instant and decaffeinated coffee were associated with equivalent reductions in the incidence of cardiovascular disease and death from cardiovascular disease or any cause," said study author Professor Peter Kistler of the Baker Heart and Diabetes Research Institute, Melbourne, Australia.
"The results suggest that mild to
moderate intake of ground, instant and decaffeinated coffee should be
considered part of a healthy lifestyle."
There is little information on the impact of different coffee preparations on heart health and survival. This study examined the associations between types of coffee and incident arrhythmias, cardiovascular disease and death using data from the UK Biobank, which recruited adults between 40 and 69 years of age. Cardiovascular disease was comprised of coronary heart disease, congestive heart failure and ischaemic stroke.
The study included 449,563 participants free of arrhythmias or other cardiovascular disease at baseline. The median age was 58 years and 55.3% were women.
Participants completed a questionnaire asking how many cups of coffee they drank each day and whether they usually drank instant, ground (such as cappuccino or filtered coffee), or decaffeinated coffee.
They were then grouped
into six daily intake categories, consisting of none, less than one, one, two
to three, four to five, and more than five cups per day. The usual coffee type
was instant in 198,062 (44.1%) participants, ground in 82,575 (18.4%), and
decaffeinated in 68,416 (15.2%). There were 100,510 (22.4%) non-coffee drinkers
who served as the comparator group.
Coffee
drinkers were compared to non-drinkers for the incidence of arrhythmias,
cardiovascular disease and death, after adjusting for age, sex, ethnicity,
obesity, high blood pressure, diabetes, obstructive sleep apnoea, smoking
status, and tea and alcohol consumption. Outcome information was obtained from
medical records and death records. The median follow up was 12.5 years.
A total of 27,809 (6.2%) participants died during follow up. All types of coffee were linked with a reduction in death from any cause.
The greatest risk
reduction seen with two to three cups per day, which compared to no coffee
drinking was associated with a 14%, 27% and 11% lower likelihood of death for
decaffeinated, ground, and instant preparations, respectively.
Cardiovascular disease was diagnosed in 43,173 (9.6%) participants during follow up. All coffee subtypes were associated with a reduction in incident cardiovascular disease.
Again, the lowest risk was observed with two to three cups a day,
which compared to abstinence from coffee was associated with a 6%, 20%, and 9%
reduced likelihood of cardiovascular disease for decaffeinated, ground, instant
coffee, respectively.
An arrhythmia was diagnosed in 30,100 (6.7%) participants during follow up. Ground and instant coffee, but not decaffeinated, was associated with a reduction in arrhythmias including atrial fibrillation.
Compared with non-drinkers, the
lowest risks were observed with four to five cups a day for ground coffee and
two to three cups a day for instant coffee, with 17% and 12% reduced risks,
respectively.
Professor
Kistler said: "Caffeine is the most well-known constituent in coffee, but
the beverage contains more than 100 biologically active components. It is
likely that the non-caffeinated compounds were responsible for the positive
relationships observed between coffee drinking, cardiovascular disease and
survival. Our findings indicate that drinking modest amounts of coffee of all
types should not be discouraged but can be enjoyed as a heart healthy
behaviour."
