data on ANP and related peptides in cardiovascular
and other disorders, and outlines the potential clinical

Background: Cardiovascular diseases (CVDs) are the leading cause of death in most countries of the world. In this study, associations between CVDs and polymorphisms of angiotensin-converting enzyme (ACE), atrial natriuretic peptide (ANP), β2-adrenal receptor (B2AR) and endothelial nitric oxide synthase (ENOS) genes were explored in a community-based setting.
Methods: Between March and May 2001, 1740 subjects ≥35 years from the Matsu area in Taiwan were recruited to this study, representing 71.6% of the target population in Matsu. After informed consent was obtained during an interview, physical examination, resting ECG, serum biochemical profile and a questionnaire survey were used to obtain information. Genomic DNA was also collected and analyzed. Owing to technical limitations, 1186 samples were analyzed. Genetic polymorphisms of the genes in question were investigated using PCR and restriction fragment length polymorphism (RFLP). The distribution of allele frequencies for these genes was derived for stroke, coronary artery disease, hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia and overweight subgroups.
Results: The ENOS Glu298Asp polymorphism was associated with hypercholesterolemia (odds ratio 0.658, 95%CI 0.460–0.940; p=0.025) and the ACE D/I variant was associated with hypertriglyceridemia (odds ratio 0.722, 95%CI 0.536–0.973; p=0.033). Polymorphisms of the other genes were not associated with any of the disease groups.
Conclusions: This community-based study reveals that genetic factors might play a role in the metabolism of lipids. The genetic risk for CVDs needs further investigation.
The clinical relevance of brain natriuretic peptide (BNP) and N-terminal (NT)-proBNP assays as a diagnostic tool and prognostic marker in patients with cardiovascular diseases has recently been confirmed. However, several studies demonstrated variation of intra-individual BNP concentrations of >30% (ranging from 30% to 50%) with reference change values at the 95% confidence interval (i.e., the estimated critical difference) ranging from 99% to 130% in healthy subjects and heart failure patients. According to this estimated confidence interval, only a great variation in plasma BNP levels should be considered significant in an individual patient (for example, a decrease of >50% or an increase of more than two-fold). Many recent clinical studies have demonstrated that BNP variations below this estimated critical difference could also have clinical relevance. Like the concentration of other neuro-hormones, levels of plasma BNP fluctuate widely and rapidly along with heart rhythm and blood pressure variations in response to physiological stimuli. However, biological variation of BNP should not be interpreted strictly as random fluctuation around a homeostatic set point, as assumed by the common model used in all studies on biological variation of BNP reported in the literature. These results cannot be directly transferred to clinical practice. While awaiting more accurate studies, we suggest that variations of plasma BNP three-fold greater than the analytical imprecision should be considered as potentially relevant from a physiological and clinical point of view.
