Predictors of B-type natriuretic peptide and left atrial volume index in patients with preserved left ventricular systolic function: An echocardiographic-catheterization study
Facteurs prédictifs du BNP et du volume de l’oreillette gauche chez les patients avec fonction systolique ventriculaire gauche préservée : une étude par échocardiographie Doppler et cathétérisme

Figure 1 : 

Scatterplot of the relationship between log-transformed data for B-type natriuretic peptide (log [BNP]) and invasively measured left ventricular end-diastolic pressure (LVEDP). The correlation coefficient was 0.50 [0.28–0.67] (p <0.001). The solid line corresponds to the regression line (LVEDP=6.1×log [BNP]+10.2) and the dotted lines correspond to its 95% confidence interval.

Figure 2 : 

Scatterplot of the relationship between left atrial volume index (LAVi) and invasively measured left ventricular end-diastolic pressure (LVEDP). The correlation coefficient was 0.48 [0.25–0.65] (p <0.001). The solid line corresponds to the regression line (LVEDP=0.26×LAVi+11.8) and the dotted lines correspond to its 95% confidence interval.
