Calcium Helps Predict Heart Attacks
Calcium buildup in the artery wall is a stage of atherosclerosis or plaque formation process. The amount of calcium found in artery is proportional to the plaque established and stated with calcium score (CS).
Generally this is a preliminary indication of coronary artery disease, because if it continues it can clog arteries.
According to HealthDay, a team from Northwestern University Feinberg School of Medicine recently researched it. Participants were 5878 men and women of various ethnicity by age 45 to 84. CS in the artery was observed by CT scan.
At the beginning of the study, no participants are known to suffer from heart disease. Participants are monitored through telephone interviews regarding the history of examinations in the hospital, the illness is experienced, and other matters related to heart health.
Observed for nearly 6 years, 209 participants experienced the various events associated with heart health. Among these are heart attacks, deaths due to heart disease, failure of heart function (cardiac arrest).
Compared with the above results, suitability of the researchers who made the prediction based on observations of CS reached 77 percent. While predictions are made without looking at the CS, only 69 percent compliance.
Researchers concluded, CS when combined with an analysis of other risk factors can increase the accuracy in predicting the risk of heart attack. Results of the research was published in the Journal of the American Medical Association, 28 April 2010 edition.
But some experts question the benefits of this research, because a scanning with CT-scan should not be done routinely. X-ray radiation that is too often also have a lot of risk, besides the high cost.
