  • Be able to understand the procedures and methods of the trial and voluntarily participate with the signature of the informed consent by the patient or his/her guardian.

You may not qualify if:

  • heart diseases: cardiomyopathy and myocarditis; structural heart diseases; coronary heart disease (acute coronary syndrome, myocardial infarction); pericardial disease; severe arrhythmias (severe tachycardia requiring pacemakers, severe rapid arrhythmias, and other arrhythmias beyond the control of medications) ; New York Heart Association (NYHA) classification heart function grading ≥III or Left Ventricular Ejection Fraction (LVEF) ≤50%;
  • poorly controlled diabetes (fasting blood glucose ≥11.1mmol/L);
  • with systolic blood pressure (SBP) \> 150mmHg and/or diastolic blood pressure (DBP) \> 100mmHg after treatment with a stable dose (at least 4 weeks) of antihypertensive drugs;
