cardiovascular system

abnormal heart morphology ( J:187437 )

• in response to pressure overload, mice exhibit increased deposition of extracellular matrix compared with wild-type mice

abnormal coronary vessel morphology ( J:187437 )

• in response to pressure overload, mice exhibit decreased number of microvessels compared with wild-type mice

increased heart weight ( J:187437 )

cardiac hypertrophy ( J:187437 )

• in response to pressure overload

increased heart left ventricle weight ( J:187437 )

• in response to pressure overload

cardiac fibrosis ( J:187437 )
