![]() They also had a more extensive pattern of calcium buildup (evident in more of the heart’s vessels and over a larger area), but similar average CAC density – the concentration of calcium buildup compared Overall, people with CAC ≥1,000 tended to be older, male, and white, and had a higher 10-year atherosclerotic cardiovascularĭisease (ASCVD) risk score on average. Only 3.8% (257 participants) had CAC at or higher than 1,000. Medical chart reviews and phone interviews were done at 9- and 12-month intervals to collect information about any hospital admissions, onset of new conditions/diagnoses, procedures orĭeaths. Participants were followed for an average of nearly 16 years. Information about lifestyle and known risk factors for cardiovascular disease, including family history of heart attack, smoking, diabetes, obesity/overweight, and CAC scores, was collected at the start of the study between July 2000 and September 2002. Years) enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA), a community-based population study, sponsored by the National Heart, Lung, and Blood Institute, of diverse adults free of known cardiovascular disease and followed over many years. They included data from 6,814 participants (age 45-84 Researchers sought to investigate their risk compared with people who had lower CAC scores as it relates not only to cardiovascular events and deaths, but also for developing other chronic conditions. But what about people whose score is at or above 1,000? Or having an event such as a heart attack or stroke. Researchers explain that people with CAC scores of >300 or >400 are generally considered to be at highest risk of developing heart disease ![]() Higher CAC scores mean there is more evidence of calcium and thickening in the inside lining of the arteries. Gives information that can help guide treatment decisions, such as the need to go on a statin or intensify lifestyle changes to lower their risk. Who have less or no calcium buildup, according to a study published in Circulation.Ĭoronary artery calcium (CAC), measured on an imaging scan, is increasingly being used as a tool – in addition to standard risk calculators – to gauge how likely someone is to develop heart disease or have a heart attack or stroke. People free of heart disease who have very high levels of calcium in the walls of the heart’s arteries are markedly more likely to have a heart attack, stroke and other heart-related events, or develop other health conditions compared with people
