- NYHA cardiac functional grading [ Time Frame: 7 days treatment ]
The cardiac functional changes between the end of medication (within 24 hrs) and baseline (prior to medication) are evaluated by the three-grade criteria (excellent, effective and no response). And calculate the effective rate.
Excellent: cardiac function improved for 2 grades and above Effective: cardiac function improved for one grade No response: failed to achieve the effective criteria.
- Other efficacy evaluations [ Time Frame: 7 days treatment ]6-Minute Walk Test (6MWT)
- Other efficacy evaluations [ Time Frame: 7 days treatment ]
2.Incidence of major cardiovascular events when follow-up (within 1 month)
- symptoms get worse (NYHA cardiac functional grading aggravates)
- increase dosage or other treatment for aggravating heart failure
- need hospitalization again for heart failure or other reasons
- death
- Other efficacy evaluations [ Time Frame: 7 days treatment ]Plasma L-carnitine level (acyl-carnitine/free carnitine)
- Other efficacy evaluations [ Time Frame: 7 days treatment ]ultrasound echocardiography to measure left ventricular ejection fraction (LVEF)
- Other efficacy evaluations [ Time Frame: 7 days treatment ]measure the N-Terminal-pro brain natriuretic peptide level in serum
