Echocardiography of Male EP4 KO Mice and Wild Type Littermates.

Table 1 gives echocardiography data for male EP4 KO mice and their wild-type littermates (WT) that were used to determine fractalkine content of the left ventricle by ELISA. Values are means ± SE.*p**p≤0.01 versus WT. Statistical analysis was performed using t-test. Abbreviations: SF, shortening fraction; EF, ejection fraction; LVDs, left ventricular dimension at systole; LVDd, left ventricular dimension at diastole; HR, heart rate; PWTd, posterior wall thickness at diastole; IVSTd, intraventricular septum thickness at diastole.
