Left ventricle
Patients in the PAR group demonstrated echocardiographic signs of early positive left ventricular remodeling (Table 6). At 6 weeks, left ventricular end diastolic diameter (LVEDD) was significantly lower in the PAR group (4.64 vs 5.01 cm, p=0.039) compared to the CVG group. By one year, LVEDD was not different (4.65 vs 4.94 cm, p=0.144) although the left ventricular end systolic diameter (LVESD) was found to be significantly smaller in the PAR group (3.04 vs 3.53 cm, p=0.024). The overall mean net change in LVESD between 6 weeks and 1 year was also more negative in the PAR group (-0.11 vs +0.13 cm, p=0.05). Left ventricular function at 6 weeks and 1 year was not different between the treatment groups, nor was the net change in function.
