Scientist shed light on how dengue adapts as it travels

Washington DC, 7 July (ANI): In a new study scientists have suggested that coronary artery calcification (CAC) scans could help detect patients at risk for premature death.

Researchers from Emory University School of Medicine, led by Leslee Shaw, PhD, professor of cardiology, collected and assessed CAC scores and risk factor data taken from 9,715 study participants between the years 1996 and 1999.

The patients, who were scanned as part a community-outreach screening program at an outpatient clinic in Nashville, showed no symptoms of coronary artery disease at the time of the scans.

Approximately 86 percent of the participants were white, eight percent were African American, four percent were Hispanic, and two percent were Asian.

Researchers found that the score accurately predicted all-cause mortality up to 15 years in the asymptomatic patients. The authors suggest that CAC scanning could help identify patients at risk for early death.

Shaw said that patients with high calcium scores might be advised by their physicians to adopt healthier lifestyles, which could lead to better outcomes and potentially help lengthen their lives.

Shaw says CAC scores have been used to estimate cardiovascular prognosis and all-cause mortality in the short term, but this study’s long-term analysis is unique.

The study is published in the online edition of Annals of Internal Medicine. (ANI)
