Telomere length prognostic for 50 to 75 year-old men with ACS

(HealthDay)—For men aged 50 to 75 years with acute coronary syndrome, short telomeres are independently associated with worse prognosis, according to a study published in the Feb. 1 issue of The American Journal of Cardiology.

Jose-Angel Perez-Rivera, M.D., from the University Hospital of Salamanca in Spain, and colleagues assessed the of , measured by quantitative in peripheral blood leukocytes of 203 men admitted with acute coronary syndrome. The men were classified into two groups according to age: 50 to 75 years, and older than 75 years. Patients underwent more than 600 days of clinical follow-up and a prognostic combined event was defined.

The researchers found that for men aged 50 to 75 years, those with short telomeres had significantly worse prognosis (P < 0.05), but this association was not seen for men aged older than 75 years (P = 0.91). For men aged 50 to 75 years, Cox analysis confirmed short telomeres as an independent prognostic risk factor.

"In conclusion, telomere length is a good predictor of cardiovascular prognosis in men admitted for , but this relation depends on the chronological age of the population studied," the authors write.
