Circulating leukocyte telomere length and oxidative stress: a new target for statin therapy.

Objectives: We investigated the relationship between prior statin therapy and leukocyte telomere length (LTL), as well as their interaction with potential new biomarkers of oxidative deoxyribonucleic acid (DNA) lesions and reactive oxygen species-induced inflammation.

Methods And Results: From patients admitted for an acute myocardial infarction, LTL was assessed by quantitative polymerase chain reaction (Q-PCR), and leukocyte Finkel-Biskis-Jinkins osteosarcoma (FOS) and 8-oxoguanine DNA glycosylase (OGG1) messenger ribonucleic acid (mRNA) levels were measured by retrotranscription Q-PCR. Patients under prior chronic statin therapy were compared with patients without statin therapy.

Serum brain-derived neurotrophic factor and platelet activation evaluated by soluble P-selectin and soluble CD-40-ligand in patients with acute myocardial infarction.

Little is known about the role of neurotrophins (NT) under adult vascular homeostasis in normal and pathological conditions. The NT family, including nerve growth factor and brain-derived neurotrophic factor (BDNF) are expressed in atherosclerotic vessels. Previous studies demonstrated that plasma BDNF levels were increased in the coronary circulation in patients with unstable angina.

Relation between body mass index, waist circumference, and death after acute myocardial infarction.

Background: An elevated body mass index (BMI) has been reported to be associated with a lower rate of death after acute myocardial infarction (AMI). However, waist circumference (WC) may be a better marker of cardiovascular risk than BMI. We used data from a contemporary French population-based cohort of patients with AMI to analyze the impact of WC and BMI on death rates.

Impact of asymmetric dimethylarginine on mortality after acute myocardial infarction.

Objective: Asymmetrical dimethylarginine (ADMA) is an endogenous competitive inhibitor of nitric oxide (NO) synthases. From a prospective cohort of patients with acute myocardial infarction (MI), we aimed to analyze the predictive value of circulating ADMA concentrations on prognosis.

Methods And Results: Blood samples from 249 consecutive patients hospitalized for acute MI <24 hours were taken on admission.

[Long-term management of post acute coronary syndrome with oral antiplatelet therapy].

Cardiovascular disease is the primary cause of early death and morbidity in the industrialized world and is becoming a growing problem in many developing countries. Coagulation inhibitors play a major role in the management of the acute phase of ACS whether in association with reperfusion strategies or not. Currently, and in accordance with the results of major randomised studies, for medium and long-term management, the association of Clopidogrel and aspirin is the treatment of choice.
