The Impacts of Cardiac Rehabilitation Program on Echocardiographic Parameters in Coronary Artery Disease Patients with Left Ventricular Dysfunction

Table 2

Echocardiographic data of patients before and after the rehabilitation period.

	Before CR	After CR	P value
LVEF (%)	45.14 ± 5.77	50.44 ± 8.70	<0.001
METs	8.00 ± 2.56	10.08 ± 3.00	<0.001
LVESD (mm)	38.91 ± 10.83	38.09 ± 9.04	0.378
LVEDD (mm)	54.63 ± 12.96	53.86 ± 8.95	0.529
Maximum heart rate	45.19 ± 98.13	56.17 ± 69.13	0.15
Test duration and recovery	20.5 ± 81.14	06.6 ± 17.15	0.57

Data are presented as mean ± SD. CR: cardiac rehabilitation; LVEF: left ventricular ejection fraction; METs: peak exercise capacity measured in Metabolic equivalents; LVESD: left ventricular end-systolic diameter; LVEDD: left ventricular end-diastolic diameter.
