C-terminal provasopressin measurement and cardiovascular disease / 中华检验医学杂志

Copeptin,the C-terminal portion of provasopressin,is a novel neurohormone of the arginine vasopressin (AVP)system,and is known to be co-released with AVP from hypothalamus.As a surrogate marker of the AVP system,copeptin has gradually replaced AVP in several clinical studies largely due to its structural and methodological advantages.Copeptin has been regarded as a marker of non-specific stress response.In recent years,copeptin attracts more and more attention especially in cardiovascular conditions (heart failure and acute coronary syndromes).The present review primarily focuses on copeptin detection,its general advantages,and its potential clinical value in a variety of cardiovascular conditions.

Laboratory artifacts caused by various sample collection times and types in cardiovascular disease / 中华检验医学杂志

Cardiovascular diseases is a common disease and induces high mortality.Blood tests are very important for the diagnosis,prognosis,monitoring and treatment of CVD.Clinicians are frequently presented with laboratory test results that are not consistent with preconceived expectations for a given case.It has been confirmed that pre-analytical quality control may be influenced by factors such as the time of sample collection.In this article different times and styles of sample collection are discussed.

Diagnostic values of N-terminal pro-B-type natriuretic peptide in elderly patients with heart failure / 中华检验医学杂志

The morbidity and mortality of heart failure (HF) were gradually incrcased,around 2％-3％ of the population suffered from HF.As a biomarker,NT-proBNP has been shown to be widely used in the diagnosis of HF patients.NT-proBNP lever is affected by many factors,especially the age,age-specific NT-proBNP lever is very important in diagnosis of elderly HF patients.
