Condition high-risk cardiac patients with a recent hospitalization for overt heart failure and a moderately preserved ejection fraction
Classification by specialty
Classification by malignancy Others
Genomic information NO

Narrative objectives1 The primary objective of this trial is to determine whether a two-lead CRT-P system will significantly improve echo-determined left ventricular ejection fraction between baseline and 6 months of two-lead CRT-P therapy in high-risk cardiac patients with a recent hospitalization for overt heart failure and a moderately preserved ejection fraction.
Basic objectives2 Safety,Efficacy
Basic objectives -Others
Trial characteristics_1 Confirmatory
Trial characteristics_2 Explanatory
Developmental phase Not applicable

Primary outcomes Significantly greater improvement in echo-determined LVEF when compared to optimal pharmacologic therapy between baseline and 6 months in high-risk cardiac patients with a recent hospitalization for overt heart failure.
Key secondary outcomes All-cause mortality, rates of recurrent heart failure and cardiovascular death (whichever comes first), changes in LVESV and LVEDV, NYHA functional class, effect of two-lead CRT-P therapy in ischemic vs. non ischemic patients with heart failure, occurrence of atrial fibrillation events, effects of two lead CRT-P on left atrial size.

In outcomes field, the entry of just a few words such as "safety" or "efficiency" will not be accepted. Specify the name of outcome measures, including the time when you plan to measure. Usually, only one primary outcome is accepted. Write the other outcomes in "secondary outcomes" field.

Key inclusion criteria Subject is age 18 or above, or of legal age to give informed consent specific to state and national law
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.
Key exclusion criteria Subject with:
- A currently implanted pacemaker, ICD, CRT-P or CRT-D generator or device component
-A history of spontaneous sustained VT=>160 bpm or VF
-Permanent or chronic AF, or cardioversion for AF within the past 3 calendar months before randomization
-Structural heart disease such as congenital heart disease, valvular heart disease, e.g., rheumatic valvular heart disease, amyloid heart disease, etc.
-Coronary artery bypass graft surgery or percutaneous coronary intervention within the past 3 calendar months before randomization
-Enzyme positive myocardial infarction within the past 3 calendar months prior to randomization
-Angiographic evidence of coronary disease who are candidates for coronary revascularization and are likely to undergo coronary artery bypass graft surgery or percutaneous coronary intervention in the foreseeable future
-Second or third degree heart block
-Irreversible brain damage from pre-existing cerebral disease
-Presence of any disease, other than the subject's cardiac disease, associated with a reduced likelihood of survival for the duration of the trial, e.g., cancer, liver failure, etc.
-Chronic renal disease with blood urea nitrogen (BUN) =>50mg/dl (18 mmol/l) or creatinine => 2.5mg/dl (221 &micro;mol/l)
Right bundle branch block or non-specific interventricular conduction delay
Subject in New York Heart Association Class IV

Subject participating in any other clinical trial
Subject unwilling or unable to cooperate with the protocol
Subject who lives at such a distance from the clinic that travel for follow-up visits would be unusually difficult
Subject who does not anticipate being a resident of the area for the scheduled duration of the trial
Subject unwilling to sign the consent for participation
Subject whose physician does not allow participation
