Experiments were designed to assess the intrinsic changes in myocardial function with age and to determine the role of increasing left ventricular mass in this process. Isometric ventricular pressure-volume curves and length-tension curves were measured in isolated perfused rat hearts of different ages and masses. Incremental tension, peak active tension, and peak passive tension were less for 10-day-old hearts than they were for older hearts subjected to proportionately equal increases in… CONTINUE READING
