The purpose of this study is to evaluate the efficacy and safety of L-carnitine injection in treatment of Chinese patients with heart failure.

A prospective, multicenter, randomized, double-blind, parallel, placebo-controlled clinical study was performed.

Treatment period: 7 days, follow-up: 1 month

Primary Outcome Measures:
  • 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.

Secondary Outcome Measures:
  • 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

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. The subject aged ≥ 18 years, men or women.
  2. The subject has a diagnosis of chronic left heart or right heart failure (a past medical history of left heart failure caused by coronary heart disease, hypertension and dilated cardiomyopathy, or a medical history of right heart failure caused by pulmonary artery hypertension (the 1st type of diagnostic classification, WHO conference, Venice, 2003) and left heart disease (the 2nd type) ;the case number of right heart failure is about 30% of the total case number).
  3. The subject needs hospitalization because of heart failure and will stay in hospital for more than 7 days.
  4. NYHA-FC is Class II- IV (Class II cases < 20%, except the refractory terminal heart failure patients).
  5. The subject's UCG shows that LVEF ≤ 45% (left heart failure).
  6. CI < 2.5 L/min/m2 or CO < 4L/min (right heart failure)
  7. The subject has signed the ICF.

Exclusion Criteria:

  1. Subjects with medical history of heart failure caused by valvular heart disease, mechanical obstruction, pericardial disease and myocardial amyloidosis.
  2. Subjects with heart function Class IV that have unstable hemodynamics and need final stage cardiac transplantation and intravenous vasoactive drugs.
  3. Subjects will leave the hospital in 7 days.
  4. Subjects with severe cerebral apoplexy (life threatening).
  5. Subjects with AMI or acute pulmonary embolism.
  6. Subjects with uremia and did not undergo dialysis.
