People who drink a moderate amount of coffee daily are less likely to develop clogged arteries that could lead to heart attacks, reveals research published online in Heart.
Researchers from South Korea found that people consuming three to five cups a day had the least risk of coronary calcium in their arteries.
There has been much debate over the effect of coffee consumption on cardiovascular health.
Despite earlier concerns about a potential increase in heart disease risk associated with drinking coffee, a recent meta-analysis of 36 studies showed that moderate coffee consumption was associated with a decreased risk of heart disease.
Coffee consumption has been associated with improved insulin sensitivity and reduced risk of type 2 diabetes, but it has also been linked to increased cholesterol concentrations and heightened blood pressure.
An international team of researchers led by the Kangbuk Samsung Hospital, Seoul, in the Republic of Korea, set out to examine the association between coffee consumption and the presence of coronary artery calcium (CAC) which is a early indicator of coronary atherosclerosis – a potentially serious condition where arteries become clogged up by fatty substances known as plaques or atheroma and which can cause the arteries to harden and narrow, leading to blood clots which can trigger a heart attack or a stroke.
They studied a group of 25,138 men and women – average age of 41 – who had no signs of heart disease, attending a health screening examination.
The participants’ screening examination included a validated food frequency questionnaire and a multidetector cardiac CT (computed tomography) for diagnostic imaging to determine levels of coronary artery calcium (CAC) scores.
Annual or biennial health screening examinations are common in Korea, because health examinations are mandatory for all workers under the Industrial Safety and Health Law there and CAC scoring has become a common heart disease screening test.
