Figure 3. Cardiomyopathy of LMNA -KO rabbits. A The heart from 18-day-old LMNA -KO rabbits and WT control. B The increased left ventricular diastolic diameter in LMNA -KO rabbits. C The decreased left ventricular ejection fraction EF in LMNA -KO rabbits. D The decreased fractional shortening in LMNA -KO rabbits. E The decreased heart rate in LMNA -KO rabbits.
