Подробное описание
With the advent of new therapies and an increasing number of long-term cancer survivors, the incidence and consequently the interest in chemotherapy-induced cardiomyopathy (CHIC) have been increasing. CHIC is a dose-dependent cardiomyopathy and presents as congestive heart failure several months to years after the administration of chemotherapy and/or chest radiation that includes the heart.
Greater than one-half of the patients exposed to just this class of drugs will show evidence of cardiac dysfunction, with 5% presenting with overt symptomatic heart failure. The overall incidence of CHIC is significantly underestimated as within the US alone, greater than 60,000 patients receive just anthracyclines every year. Despite this, there is little data on their response to conventional heart failure therapy. There is some preliminary evidence from two small, retrospective case-series suggesting that patients with CHIC and evidence of conduction tissue disease (i.e. a wide electrocardiographic depolarization duration (QRS) may significantly benefit from cardiac resynchronization therapy (CRT).
MADIT-CHIC is a multicenter, non-randomized, prospective observational study. The primary aim is to determine if CRT-D (Defibrillator) in high-risk patients with chemotherapy-induced cardiomyopathy will significantly improve left ventricular ejection fraction (LVEF) by echocardiography within 6 months of initiating CRT without adversely affecting mortality.
The study will last 6 months and will be conducted in 10-15 clinical centers in the United States.
Following implantation of the CRT-D device (Defibrillator), patients will be followed for 6 months. The first follow-up contact will be by phone at which time study personnel will review the patient's health status. The last study contact will be a 6-month clinic visit. At the 6-month visit, the patient's health status will be reviewed, the functioning of the CRT-D (Defibrillator) will be tested and an echocardiogram will be conducted. After the 6-month visit, the study-required follow-up will have been completed and patients will continue to have CRT-D (Defibrillator) clinical follow-up based on their physicians direction.
During the course of the study, Subjects will as outlined in the inclusion criteria continue 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, Angiotensin converting enzyme (ACE) inhibitors and/or angiotensin receptor blocker (ARB), Aldosterone antagonists and/or Beta-blockers unless the subject is not indicated, contraindicated, or is intolerant of medication.

Inclusion Criteria:
- Age 18 (or of legal age to give informed consent specific to state and national law) up to 80 years of age
- Male or Female
- Without clinical heart failure at initiation of chemotherapy/radiation-induced treatment for an underlying malignancy, but developed clinical heart failure (cardiomyopathy: reduced left ventricular ejection fraction (LVEF) with a left bundle branch block (LBBB)-type of conduction disturbance; see next inclusion item) 6 months or more after initiation of the chemotherapy without other evident cause of the cardiomyopathy.
Eligible for implantation of a CRT-D (cardiac resynchronization therapy-defibrillator) device according to one of the following options in currently available guidelines:
- Class 1: Left ventricular ejection fraction (LVEF) less than or equal to 35% AND sinus rhythm AND LBBB (left bundle branch block) with a QRS (electrocardiographic depolarization duration) duration greater than or equal to 150ms AND NYHA (New York Heart Association) class II, III or ambulatory IV symptoms on guideline-directed medical therapy
- Class 2a1: Left ventricular ejection fraction (LVEF) less than or equal to 35% AND sinus rhythm AND left bundle branch block (LBBB) with a QRS (electrocardiographic depolarization duration) duration 120-149ms AND New York Heart Classification (NYHA) class II, III or ambulatory IV symptoms on guideline-directed medical therapy
- Class 2a2: Left ventricular ejection fraction (LVEF) less than or equal to 35% AND sinus rhythm AND Non-left bundle branch block (LBBB) with a QRS(electrocardiographic depolarization duration) duration greater than or equal to 150ms AND New York Heart Classification (NYHA) class III or ambulatory IV symptoms on guideline-directed medical therapy
- 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, Angiotensin converting enzyme (ACE) inhibitors and/or angiotensin receptor blocker (ARB), Aldosterone antagonists and/or Beta-blockers unless the subject is not indicated, contraindicated, or is intolerant of medication.
Exclusion Criteria:
- Currently implanted pacemaker or implantable cardioverter defibrillator (ICD) device
- Previous implant with a CRT (cardiac resynchronization therapy)/CRT-D (cardiac resynchronization therapy-defibrillator) device
- Cardiac condition not presumed to be caused by chemotherapy
- Documented symptoms or hemodynamically unstable ventricular tachyarrhythmia
