Narrative objectives1

The objective is to determine the optimum dose of the beta-blocker, carvedilol by comparing the efficacy and safety of 3 doses in patients with chronic heart failure from systolic dysfunction, to investigate the background factors of responders and non-responders, and to establish a method for individualized treatment employing the drug beta-blocker.

Developmental phase

Primary outcomes

a composite of cardiovascular death and unplanned admission to hospital for heart failure

Key secondary outcomes

1) cardiovascular death, 2) unplanned admission to hospital for heart failure, 3) a need to modify treatment procedures for heart failure, new addition of anti-cardiac failure drugs administered over a 3-day period, 4) death from cardiac failure, 5) sudden death (including death from arrhythmia), 6) aggravation of SAS 1 Met or more, progression of NYHA functional class by 1 grade or more, 7) left ventricular ejection fraction, and 8) BNP.

Interventions/Control_1

2.5mg/d: Carvedilol will be up-titrated from 1.25 mg twice daily to the target dose twice daily within an 8 week period based on patient tolerability. Patients will be maintained at the target dose or the maximum tolerated dose for the duration of the study.

Interventions/Control_2

5mg/d: Carvedilol will be up-titrated from 1.25 mg twice daily to the target dose twice daily within an 8 week period based on patient tolerability. Patients will be maintained at the target dose or the maximum tolerated dose for the duration of the study.

Interventions/Control_3

20mg/d:Carvedilol will be up-titrated from 1.25 mg twice daily to the target dose twice daily within an 8 week period based on patient tolerability. Patients will be maintained at the target dose or the maximum tolerated dose for the duration of the study.

Key inclusion criteria

1) Underlying illness: Chronic heart failure patients with stable symptoms (no fluctuation in NYHA heart function class prior to start of drug administration) and not currently taking carvedilol.
Definition of "stable": No fluctuation in NYHA heart function class prior to start of drug administration (fluctuation from IIM to III or III to IIM interpreted as stable).
2) Degree of severity: Patients with NYHA heart function class II or III and EF of 40% or lower.
3) Age: Patients age 20 years or older to less than 80 years at the start of the observation period.
4) Inpatient/outpatient status: Without regard to inpatient or outpatient status; however, the time frame and reason for any changes to be noted in study tables.
5) Sex: Without regard to sex.

12) Poorly controlled diabetes.
13) Severe complication by any of the following illnesses: kidney disease , liver disease , anemia.
14) Thyroid dysfunction poorly controlled by treatment.
15) Pregnant, lactating, or possibly pregnant or desiring to become pregnant during the study period.
16) History of drug hypersensitivity to carvedilol.
17) Carvedilol administration is deemed contraindicated.
18) Written consent is not obtained.
