Abstract
The incidence of systemic arterial hypertension is increasing worldwide. The foundation of prevention is identification of people with hypertension. Nowadays, biomarkers are used to diagnose and stratify diseases and estimates prognosis. The objective of this study was to review articles published over the last 5 years on the subject of biomarkers of cardiovascular diseases. The PubMed, SciELO, Science Direct and MEDLINE databases were searched using the keywords: arterial hypertension, cardiovascular biomarkers, nitric oxide, endothelial function and asymmetric dimethylarginine. The studies reviewed show that cardiovascular diseases have complex etiologies. This article describes evidence demonstrating interactions between nitric oxide and asymmetric dimethylarginine that are involved in regulation, in metabolism, and in determination of intracellular levels, and also discusses other biomarkers related to hypertension. Some studies indicate that biomarkers are useful tools for prediction of cardiac events, whereas others state that they have little to contribute to assessments. Careful selection of tests and combinations of tests may be the key to validating use of biomarkers, in view of their low specificity for diagnosing hypertension.
