ABSTRACT
AIM:
Mitochondrial DNA (mtDNA) copy number variation (CNV), which reflects the oxidant-induced cell damage, has been observed in a wide range of human diseases .However, whether it correlates with heart failure , which is closely related to oxidative stress, has never been elucidated before .We aimed to systematically investigate the association between leukocyte mtDNA CNV and heart failure risk and prognosis .METHODS:
A total of 1 700 hospitalized patients with heart failure and 1 700 age-and gender-matched community population were consecutively enrolled in this observational study , as well as 1 638 ( 96.4%) patients were fol-lowed prospectively for a median of 17 months (12~24 months).The relative mtDNA copy number in leukocyte of peripheral blood or cardiac tissue was measured in triplicate by quantitative real-time PCR method .RESULTS:
Patients with heart failure possessed much lower relative mtDNA copy number compared with control subjects (P mtDNA copy number depletion is an independent risk factor for heart failure and predicted higher risk of cardiovascular deaths in patients with heart failure .
