Korábbi kezelés

• Diagnosis of peripartum or chemotherapy-induced cardiomyopathy within the past 12 months;
• Those who have participated in any drug clinical trial within the previous 3 months;

Más betegség

• Hypertrophic cardiomyopathy with outflow tract obstruction, constrictive pericarditis, significant and uncorrected valvular heart disease (severe regurgitation or severe stenosis or valvular disease requiring surgery), congenital heart disease requiring surgery but not yet undergoing surgical treatment, primary pulmonary hypertension or secondary severe pulmonary hypertension (≥ 70 mmHg);
• Right heart failure due to lung disease;
• Subjects with chronic heart failure complicated with acute hemodynamic disturbance or acute decompensation within recent 1 month (symptoms and signs indicate chronic heart failure is aggravated, and intravenous drug therapy may be required);
• Angina pectoris within 3 months;
• Myocardial infarction within the past 6 months;
• Cerebrovascular accident, revascularization (PCI or other surgery), cardiac surgery, carotid artery or other large vessel surgery within the past 6 months;
• History of heart transplantation, use of ventricular assist device (VAD) or preparation for heart transplantation, VAD;
• Serious arrhythmia (sustained ventricular tachycardia or other conditions meet the criteria according to the investigator's judgement );
• Severe neurological disorders (Alzheimer's disease, progressive parkinsonism);
• The subjects with tumor history or is suffering from tumor now, or with precancerous lesions confirmed by pathological examination (such as breast ductal carcinoma in situ, or cervical dysplasia), or with malignant mass found by examination (physical examination, X-ray examination or B ultrasound examination or other means);
• The subjects with proliferative glands or adenomas that are found to have endocrine activity that affects cardiac function or endocrine function detected by examinations (physical examination, X-ray examination, B ultrasound examination or other means), such as pheochromocytoma, thyromegaly, etc. (patients with euthyroid thyroid or normal thyroid function do not need to be excluded);

Laborértékek
