Figure 3From: Left ventricular filling pressure assessed by exercise TDI was correlated with early HFNEF in patients with non-obstructive hypertrophic cardiomyopathy Comparison of NT-proBNP levels at rest between the four groups. Group A: baseline E/Em < 10 and stress E/Em < 10 (n = 17). Group B: baseline E/Em < 10 and stress E/Em > 10 (n = 5). Group C: baseline E/Em > 10 and stress E/Em > 10 (n = 5). Controls (n = 31). *P < 0.05 vs. group B.Back to article page
