By a News Reporter-Staff News Editor at Hematology Week -- Fresh data on Peripheral Artery Disease are presented in a new report. According to news reporting from Berlin, Germany, by NewsRx journalists, research stated, "Short telomere length has been described to be associated with biological aging including atherosclerosis phenotypes. However, information in patients with symptomatic peripheral arterial disease (PAD) is sparse."

The news correspondents obtained a quote from the research, "We therefore aimed to investigate whether inter-individual differences in relative telomere length (RTL) are associated with symptomatic PAD. We measured RTL by a quantitative PCR method in the CAVASIC Study, a cohort of 241 male Caucasian patients diagnosed with intermittent claudication and 249 age-and diabetes-matched controls. We observed significantly shorter mean RTL in patients than in controls (1.24 +/- 0.19 vs. 1.32 +/- 0.23, p< 0.001). Each shortening of RTL by one standard deviation significantly increased the odds for PAD by 44%: age-adjusted OR = 1.44 (95% CI 1.19-1.75, p< 0.001). This association remained significant after additional adjustment for log-C-reactive protein, glomerular filtration rate, HDL cholesterol, current smoking and log N-terminal pro-B-type natriuretic peptide (NT-proBNP). Excluding patients with prevalent cardiovascular disease revealed very similar results. When we compared the model fit of the various adjustment models including cardiac risk factors and/or NT-proBNP the addition of RTL significantly improved discrimination between patients and controls. This study in a male cohort of patients with intermittent claudication and age-and diabetes-matched controls indicates a significant association of shorter relative telomere length with PAD. Our results reinforce RTL as a marker for PAD that reflects the influence of genetic and environmental risk factors."

According to the news reporters, the research concluded: "Moreover, the association remains significant after excluding patients and controls free from prevalent cardiovascular disease."
