Up to three cups of coffee per day is associated with a lower risk of
stroke and fatal heart disease, according to research presented at ESC
Congress 2021.1,2

"To our knowledge, this is the largest study to systematically assess
the cardiovascular effects of regular coffee consumption in a population without diagnosed heart disease," said study author Dr. Judit Simon, of
the Heart and Vascular Centre, Semmelweis University, Budapest, Hungary.
"Our results suggest that regular coffee consumption is safe, as even high daily intake was not associated with adverse cardiovascular outcomes
and all- cause mortality after a follow-up of 10 to 15 years," she
continued. "Moreover, 0.5 to 3 cups of coffee per day was independently associated with lower risks of stroke, death from cardiovascular disease,
and death from any cause." Even though coffee is among the most consumed beverages in the world, little is known about the long-term impact of
regular consumption on cardiovascular health.
This study investigated the association between usual coffee intake and incident heart attack, stroke and death. The study included 468,629 participants of the UK Biobank with no signs of heart disease at the
time of recruitment. The average age was 56.2 years and 55.8% were women.
Participants were divided into three groups according to their usual
coffee intake: none (did not consume coffee on a regular basis, 22.1%), light-to- moderate (0.5 to 3 cups/day, 58.4%) and high (more than 3
cups/day, 19.5%).
The researchers estimated the association of daily coffee consumption with incident outcomes over a median follow-up of 11 years using multivariable models. The analyses were adjusted for factors that could influence the relationship including age, sex, weight, height, smoking status, physical activity, high blood pressure, diabetes, cholesterol level, socioeconomic status, and usual intake of alcohol, meat, tea, fruit and vegetables.
Compared to non-coffee drinkers, light-to-moderate consumption was
associated with a 12% lower risk of all-cause death (hazard ratio
[HR]=0.88, p<0.001), 17% lower risk of death from cardiovascular disease (HR=0.83, p=0.006), and 21% lower risk of incident stroke (HR=0.79; p=0.037).
To examine the potential underlying mechanisms, the researchers analysed
the association between daily coffee intake and heart structure and
function over a median follow-up of 11 years. For this, they used data
from 30,650 participants who underwent cardiac magnetic resonance imaging (MRI), which is considered the gold standard for the assessment of
cardiac structure and function.
Dr. Simon said: "The imaging analysis indicated that compared
with participants who did not drink coffee regularly, daily
consumers had healthier sized and better functioning hearts. This
was consistent with reversing the detrimental effects of ageing
on the heart." She concluded: "Our findings suggest that coffee
consumption of up to 3 cups per day is associated with favourable cardiovascular outcomes. While further studies are needed to explain
the underlying mechanisms, the observed benefits might be partly
explained by positive alterations in cardiac structure and function." ========================================================================== Story Source: Materials provided by European_Society_of_Cardiology. Note: Content may be edited for style and length.
