Figure 4: Nr2f2mutant rats exhibited superior left ventricular function.

Cardiac parameters of male hypertensive rats (n=12) and Nr2f2mutant rats (n=12) as determined by echocardiography. (a) Fractional shortening (FS), (b) velocity of circumferential shortening (Vcf) (c) fractional shortening/myocardial performance index (FS/MPI). Levels of statistical significance for all data were analyzed by independent sample t-test; *P<0.05.
