Primary Outcome Measures

Name	Time	Method
New YorkHeart Association (NYHA)	12weeks	The scale is divided into four levels; Grade 1 is unrestricted activity. Daily physical activity does not cause significant shortness of breath, fatigue or palpitations Grade 2 is a mild limitation of activity. Asymptomatic at rest, daily activities may cause significant shortness of breath, fatigue or palpitations Grade 3 is marked limitation of activity. May be asymptomatic at rest, but may cause significant shortness of breath, fatigue, or palpitations with less than daily activity.; Grade 4 is symptomatic at rest, with discomfort associated with any physical activity. Class IVa for those who can move around indoors or at the bedside without intravenous drug administration; Class IVb for those who cannot get out of bed and require intravenous drug administration.
left ventricle global longitudinal strain, LVGLS	12weeks	The magnitude of overall longitudinal myocardial strain in the left ventricle on two-dimensional speckle tracking echocardiograms as an average of the peak longitudinal strain in all myocardial segments. The normal range is (-25% to -17%) in men and (-25% to -18%) in women.

Secondary Outcome Measures

Name	Time	Method
Average heart rate	12weeks	One-minute average heart rate (at rest).
hypertension	12weeks	Blood pressure included both systolic and diastolic blood pressure and was observed before and after the intervention for any reduction in blood pressure.
