The meaning of neutrophil-lymphocyte ratio in patients with cardiovascular diseases
Abstract
Cardiovascular diseases (CVD) are still the most often cause of mortality in the population. The important role in the development of cardiovascular diseases is a low-grade inflammation. One of the indicators of this state is neutrophil- -lymphocyte ratio (NLR). Neutrophil-lymphocyte ratio is defined as the quotient of the number of neutrophils and lymphocytes. Still unknown is the normal value of NLR. Normal and pathological values depend on the kind of disease. The meaning of NLR has been proven in some cardiovascular diseases such as ischemic heart disease, arrhythmias or hypertension. In these diseases, NLR is an important predictor of worse prognosis, shorter time of survive or life- -threatening arrhythmias. The prevalence of CVD, even in young population, is the main cause of the search for new, low-cost and available methods for diagnosing cardiovascular diseases.
