How calcium in coronary arteries can predict future heart health

High cholesterol levels can indicate that a person is at risk; but scientists can also test CAC levels directly. Using a CT scan to take numerous sectional pictures of the heart, doctors can see specks of CAC.

ISLAMABAD(Online): According to one new study, having high levels of calcium in the coronary arteries could be responsible for detrimental changes to the structure of the heart. A new study investigates calcium and heart disease.

“Heart disease is the leading cause of death for men and women,” according to the Centers for Disease Control and Prevention (CDC). Being able to identify people at risk is therefore a crucial public health issue. One way to determine a person’s risk of heart disease, stroke, or heart attack is by looking at their coronary artery calcium (CAC) levels. Calcium plays a number of roles in the body, including keeping bones healthy.

However, calcium present in coronary arteries can lead to the accumulation of plaque. Over time, this calcified substance can cause atherosclerosis, or a narrowing of the arteries. Atherosclerosis restricts blood flow and oxygen supply to vital organs, potentially resulting in a heart attack or stroke. High cholesterol levels can indicate that a person is at risk; but scientists can also test CAC levels directly. Using a CT scan to take numerous sectional pictures of the heart, doctors can see specks of CAC.

A person’s scores tend to range from zero to over 400. The higher the score, the higher the risk of developing cardiovascular disease. Cholesterol guidelines from 2018 recommend a CAC scan for people ages 40–75 whose risk status is “uncertain,” note the American Heart Association (AHA). A new study, the results of which now appear in the journal Circulation: Cardiovascular Imaging, has examined the CAC scores of younger people and drawn some interesting conclusions. Heart abnormalities The scientists used data from almost 2,500 people to track CAC and heart structure differences between young adulthood and middle age. Women made up 57% of the group, and 52% of participants were white.

They took data from participants in the Coronary Artery Risk Development in Young Adults (CARDIA)study, which began in the 1980s with the aim of identifying young adult risk factors for cardiovascular disease. “We looked at early adulthood to middle age because this is a window in which we can see abnormalities that might not be causing symptoms, but could later increase the risk of heart problems,” explains study co-author Dr. Henrique Turin Moreira. The researchers compared test results from years 15 and 25 of the CARDIA study period. At the 25-year mark, the average age of the group was around 50.
