Brief Summary:
The purpose of this trial or study is to determine if pacemaker therapy can be a beneficial alternative to conventional medical therapy in patients with a history of moderate heart failure. The investigators are looking to enroll approximately 180 people in this trial. Patients will be randomized in two groups. One group will be implanted with a pacemaker and will continue to receive conventional medical therapy as prescribed by their doctor. The second group will continue to receive conventional medical therapy as prescribed by their doctor and will not be implanted with a pacemaker. Clinical histories, physical exams, and external device testing will be collected both at the time of enrollment in the trial and during follow-up study visits. Patients who enter the study will be seen for study visits at 1 month, 3 and 6 months.

Condition or disease Intervention/treatment Phase
Congestive Heart Failure Left Bundle Branch Block Heart Failure, Systolic Device: Two-lead CRT-P Phase 3

Detailed Description:

MADIT-ASIA is a multicenter, prospective, randomized clinical study. The primary aim is to show that two lead CRT-P with guideline-based optimal pharmacological therapy is associated with a significantly greater improvement in left ventricular ejection fraction (LVEF) at 6 months compared with guideline-based optimal pharmacologic therapy only.

The study will be initially conducted at approximately 25 centers in up to 9 countries in Asia including India, Thailand, Taiwan, Malaysia, China, Japan, South Korea and Singapore. If necessary, more sites may be invited to participate to meet the enrollment goal.

Following randomization, subjects will have scheduled clinic visit follow-ups at 1, 3 and 6-month intervals. Relevant event history, cardiac medications, physical assessment, device interrogation/programming status and adverse events will be collected at each follow-up visit. At the 6-month visit, a repeat echocardiogram and a 12-lead ECG will be obtained. Subjects will be followed through the 6 month visit. After that, subjects will have a safety follow up contact at the end of the study. The study will end when the last randomized subject reaches the 6 months visit.

Arm Intervention/treatment
Experimental: Device Arm: Two Lead CRT-P
Intervention: Device: Two-lead CRT-P. Patients will be implanted with a two lead CRT-P system: right atrial lead, left ventricular lead and a dual chamber pacemaker. Patients in this group will also be under optimal pharmacologic therapy.
Device: Two-lead CRT-P
The two lead CRT-P will consist of a dual chamber pacemaker, a right atrial lead and a left ventricular lead.

No Intervention: Control: Optimal Pharmacologic Therapy
The control group will be managed on optimal pharmacologic therapy only. They will not be implanted with a device.

Primary Outcome Measures :
  1. Primary Endpoint [ Time Frame: 6 months post randomization ]
    The primary endpoint will be the change in left ventricular ejection fraction (LVEF) from baseline to six months.

Secondary Outcome Measures :
  1. All-cause mortality [ Time Frame: 6 months post randomization ]
  2. Recurrent heart failure or cardiovascular death, whichever comes first [ Time Frame: 6 months post randomization ]
  3. Changes in Left Ventricular End Systolic Volume (LVESV) and in Left Ventricular End Diastolic Volume (LVEDV) [ Time Frame: 6 months post randomization ]
  4. Change in NYHA functional class [ Time Frame: 6 months post randomization ]
  5. Atrial fibrillation events [ Time Frame: 6 months post randomization ]
  6. Change in left atrial size [ Time Frame: 6 months post randomization ]

  • Hospitalization for heart failure using the Framingham criteria requiring medical treatment more than 4 weeks ago but less than six months prior to randomization date
  • Subject in sinus rhythm
  • Subject with QRS duration >110 milliseconds and left bundle branch block or incomplete left bundle branch block
  • Subject with ejection fraction 36-50%
  • Subject with ischemic or non-ischemic heart disease
  • Subject on stable* optimal pharmacologic therapy for the cardiac condition that is guideline-based and may include one or more of the following medications: Loop diuretics (e.g., furosemide, bumetanide, torsemide) unless the subject is not indicated, is contraindicated, or is intolerant of loop diuretics; Angiotensin converting enzyme (ACE) inhibitors and/or angiotensin receptor blocker (ARB) unless the subject failed, is not indicated, or is contraindicated for these therapies; Aldosterone antagonists unless the subject is not indicated, or is intolerant of aldosterone antagonists; Beta-blockers unless the subject is not indicated, contraindicated, or is intolerant of beta-blockers. The choice of selective or non-selective beta-blockers use is left to the Investigator's discretion * For purposes of the study, "stable" is defined as beta blockers and ACE/ARB for at least three months prior to randomization, unless contraindicated or not tolerated, with stable doses for at least one month prior to randomization. It is permissible for diuretic and aldosterone antagonist dosage to have been adjusted as necessary.
