Conditions: Heart Failure, Congestive
Keywords: Systolic heart failure Bisoprolol Concor Echocardiogram
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 180
Healthy volunteers: no

Brief summary:
This is a prospective, open-labeled, multi-centric trial to evaluate the effect of bisoprolol (between low dose and high dose) on surrogate markers of heart failure in Korea.

Detailed description:
Subjects with systolic congestive heart failure (CHF) will be enrolled in this study after proper evaluation of NT-proBNP, global assessment of CHF, 6-minute walking test and improvement score of New York Heart Association (NYHA) and echocardiogram (left ventricular chamber size and ejection fraction \[LVEF\]). Each subject will be orally administered bisoprolol for 6 months starting at 1.25 mg at the Week 0 and titrated up to 10 mg during the 6 month period if the persistent standing systolic blood pressure (SBP) is greater than (\>) 90 millimeter of mercury (mm Hg) and there is no symptom of hypotension at the current dose medication (syncope, loss of consciousness, dizziness when standing up).

OBJECTIVES

Primary objective:

• To evaluate the effect of bisoprolol (between low dose and high dose) on surrogate markers of heart failure in Korea

Secondary objectives:

* To evaluate bisoprolol for the effects on clinical improvement of heart failure in Korea:

  1. New York Heart Association (NYHA),
  2. 6-minutes walking test
  3. Echocardiogram (left ventricular chamber size and LVEF)
* Hospitalization due to heart failure
* To evaluate the safety and tolerability of bisoprolol
* Global assessment of CHF

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: Low Dose Bisoprolol intervention 2: High Dose Bisoprolol
Intervention descriptions: intervention 1: Bisoprolol tablet (Concor) will be administered orally at a starting dose of 1.25 milligram (mg) once daily for 2 weeks. The dose will be further escalated from 1.25 mg to 2.5 mg once daily after 2 weeks and will be administered up to 26 weeks, only if the previous administered dose is well tolerated. If the subject could not tolerate the increased dose, then the last tolerated dose will be maintained up to 26 weeks. intervention 2: Bisoprolol tablet (Concor) will be administered orally at a starting dose of 3.75 mg once daily for 2 weeks. The dose will be subsequently increased to 5 mg, 7.5 mg, or 10 mg once daily every two weeks and will be administered up to 26 weeks, only if the previous administered dose is well tolerated. If the subject could not tolerate the increased dose, then the last tolerated dose will be maintained up to 26 weeks.
