Popis: Introduction and objectives. NT-proBNP is useful in the diagnosis of heart failure and ventricular dysfunction. Left atrioventricular plane displacement (AVPD) is a consolidated index of ventricular function. Our objective was to carry out a multicenter population-based study to establish the relationship between plasma NT-proBNP levels with AVPD values. Patients and method. We studied 215 subjects (age 66 ± 9 years; 57.7% women) chosen from a random sample of 432 people from the Community of Valencia, who previously reported suffering from some degree of dyspnea. Doppler echocardiography was done, AVPD was calculated and plasma NT-proBNP concentrations were determined. All studies were completed in 194 patients. Results. For the whole population NT-proBNP was 88 (02,586) pg/ml and AVPD was 11.9 ± 1.6 mm. NT-proBNP concentration correlated well with AVPD (r = 0.44; p < 0.00001), and higher peptide levels were obtained in AVPD quartiles that indicated less displacement (p < 0.05). When NT-proBNP values were grouped according to their association with AVPD lower or higher than the 50th percentile AVPD, the difference was significant at p < 0.01. When AVPD values lower and higher than 10 mm were compared, NT-proBNP values were higher in persons with AVPD lower than 10 mm (p < 0.05). Conclusions. This population study found higher NTproBNP concentrations in subjects with lower AVPD, and illustrates the potential diagnostic usefulness of NTproBNP in clinical practice.
