Figure 1From: Increased cardiac contractility by decreased HAX-1 expressionWT: Wild type, HAX-1 KO HE: HAX-1 knockout heterozygous. A: EF% (percentage of ejection fraction) and FS% (percentage of fractional shortening) by echocardiography; B: Rates of contraction (+dp/dt) and relaxation (-dp/dt) by Langendorff perfusion. *: P<0.05, compared with WT.Back to article page
