入选标准
- •1.Clinically stable patients with left-ventricular dysfunction (LVEF = 45%) after myocardial infarction, whereby the MI occurred 6 or more months before randomization.
- •2.NYHA class I-II.
- •3.Left-ventricular ejection fraction = 45%, confirmed by any imaging technique within the last 3 months prior to screening visit will be accepted for screening purposes. If no data are available, an echocardiography has to be performed at screening for inclusion.
- •4.Treatment with evidence-based therapy for left-ventricular dysfunction post MI for at least 4 weeks prior to screening visit. This therapy has to include at least an ACE inhibitor or an ARB. Beta-blockers, diuretics, MRAs, antiplatelet therapy, statins, and aspirin are to be used if indicated. Treatment with stable doses of ACE inhibitors or ARBs using at least half of the recommended target dose (as defined in the ESC guidelines, see appendix 16.4) = 4 weeks prior to the screening visit is mandatory.
- •5.No planned changes to post MI drug therapy during the active treatment phase of the study.
- •6.Men or confirmed postmenopausal women (defined as exhibiting spontaneous amenorrhea for at least 12 months before screening or as exhibiting spontaneous amenorrhea for 6 months before screening with documented serum FSH levels > 40 mIU/mL) or women without childbearing potential based on surgical treatment 6 weeks before screening such as bilateral tubal ligation, bilateral oophorectomy with or without hysterectomy (documented by medical report verification).
- •Men of reproductive potential must agree to use 2 reliable and acceptable methods for contraception simultaneously when sexually active and not to act as sperm donor. This applies for the time period between signing of the informed consent form and 12 weeks after the last administration of study drug.
- •Acceptable methods of contraception include, but are not limited to, (i) condoms (male or female) with or without a spermicidal agent; (ii) diaphragm or cervical cap with spermicide; (iii) intra-uterine device; (iv) hormone-based contraception.
- •7.Age: 40 to 79 years (inclusive) at the screening visit.
- •8.Race: Caucasian
- •9.Ability to understand and follow study-related instructions.
- •10.Written informed consent. The informed consent must be signed before any study specific tests or procedures are done.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 30
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 18
排除标准
- •Medical and surgical history
- •1.Non-ischemic causes for cardiomyopathy will be excluded (including, but not limited to: primary cardiomyopathy, constrictive, restrictive or hypertrophic cardiomyopathy, acute myocarditis, cardiomyopathy secondary to cardiotoxic chemotherapeutic agents).
- •2.Hospitalization for decompensated heart failure within the last 3 months prior to randomization.
- •3.Coronary revascularization within 6 weeks prior to randomization or if revascularization is anticipated or needed during the study duration.
- •4.Clinically relevant, (i.e. requiring revascularization [such as coronary artery bypass grafting or percutaneous coronary intervention]) cardiac ischemia in a stress test within 3 months before screening.
- •5.Previous assignment to treatment during this study.
- •6.Any planned intervention such as: implantation of an implantable cardioverter defibrillator, implantation of cardiac resynchronization therapy devices or implantation of left ventricular assist devices, bypass operation, listing for heart transplantation or any other planned operations and medical interventions.
- •7.Patients carrying implantable cardioverter defibrillators, cardiac resynchronistaion therapy devices or left ventricular assist devices that had events such as ventricular tachycardias, ventricular fibrillation in the last 6 months before randomization while carrying the devices
- •8.Primary and uncorrected valvular disease with foreseen requirement of valve repair within the next 6 months.
- •9.Any stroke, TIA, any acute coronary syndrome within 6 months prior to randomization.
- •10.Clinically relevant hepatic dysfunction at the screening visit indicated by at least one of the following:
- •ohepatic insufficiency (Child-Pugh B or C) as documented in medical history
- •ototal bilirubin > 2 times the upper limit normal (ULN) and
- •-alanine amino transferase (ALT) > 3 times the ULN
- •-glutamate dehydrogenase (GLDH) > 3 times the ULN
- •-gamma glutamyl transpeptidase (?GT) > 5 times the ULN.
- •11.Known hypersensitivity to the study drugs (active substances or excipients of the preparations).
- •12.Patients suffering from any autoimmune disease.
- •13.Medical condition or history thereof that in the opinion of the investigator would impair the ability to complete the planned study procedures.
- •14.Anemia as evidenced by hemoglobin values of = 10 mg/dl at screening.
- •15.Hyperthyreosis or hypothyreosis as evidenced by TSH values outside the reference range at screening.
- •16.Any deviation from normal laboratory values that in the opinion of the investigator would impair the ability to complete the planned study procedures or pose a potential safety risk.
- •Medication, drug use and special behavioral patterns
- •17.Use of antacids containing hydroxide salts during the study conduct. Patients using hydroxide salt containing antacid should be switched to proton pump inhibitors at least one week before treatment with study drug (day 0).
- •18.Consumption of grapefruit juice or St. John’s wort during the study conduct and two weeks before starting the clinical phase of the study.
- •19.Medication with CYP3A4 inhibitors (amiodarone, dronedarone, diltiazem, verapamil, fluvoxamine, nefazodone, clarithromycin, and antimycotics such as fluconazole, itraconazole, ketoconazole, miconazole, posaconazole, voriconazole) within 4 weeks before screening and during the study.
- •20.Suspicion of drug or alcohol abuse (defined as more than 24 g of pure alcoho
