passive left ventricular stiffness in infarcted hearts was higher than for noninfarcted hearts throughout the 6 weeks during early filling ( 11.1 +/- 3.9 vs. 7.1 +/- 1.4 mmhg/ml , p less than 0.001 ) but decreased ( p less than or equal to 0.05 ) after 14 days during the prerupture phase ( 11.3 +/- 5.3 vs. 6.2 +/- 3.0 mmhg/ml , p less than 0.005 ) .
