Drinking two to three cups of coffee a day is linked with a longer lifespan and lower risk of cardiovascular disease compared with avoiding 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.

[...] 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. [...]

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. [...]

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."
