People who drink coffee moderately could be 11 per cent less likely to suffer from heart failure than the general populace, a new study has shown.
The research, which was published in the scientific journal Circulation: Heart Failure, revealed the risk of suffering from this cardiac event is 11 per cent lower for habitual coffee consumers than other people.
The study, led by international healthcare specialists at Beth Israel Deaconess Medical Center (BIDMC), found a "statistically significant J-shaped relationship" between people who enjoy the beverage and their risk of heart failure.
The healthiest amount of coffee to drink every day was found to be two eight-ounce American servings (480 ml), with protection remaining but decreasing until five of these servings are consumed.
After this point, there ceases to be a health benefit to caffeine intake, with people who drink more than this at risk of suffering ill effects.
Investigators analysed five studies – one in Finland and four in Sweden – that looked at the link between heart failure and coffee consumption.
It involved examining 140,220 participants and a total of 6,552 cardiac failures.
Senior author of the study and BIDMC Cardiovascular Institute physician Murray Mittleman said the lower risk of heart failure could be due to the theory that coffee consumption reduces the likelihood of a person developing type 2 diabetes.
"A good deal of research" supports this claim, she declared.
Furthermore, the drink could also help to prevent high blood pressure in people, the expert noted, adding: "There is clearly more research to be done."
The study did not examine the strength of the coffee preferred by research participants or even if they were drinking caffeinated or non-caffeinated brands.
"Compared with no consumption, the strongest protection we observed was at about four European, or two eight-ounce American, servings of coffee per day," lead study author and a post-doctoral fellow in BIDMC's cardiovascular epidemiological unit Elizabeth Mostofsky said.
"Like with so many other things we consume, it really depends on how much coffee you drink," she remarked.
Other research into coffee led by scientists in the Harvard School of Public Health and published in Circulation has indicated coffee could protect against the likelihood of a person suffering from a stroke.
