Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Signing informed consent;
  • Male or female aged 18 to 75 years old;
  • AMI patients with selective PCI indication primary PCI patients are exclusive;
  • No history of CABG or PCI;
  • CCTA at least one in-segment ≥20% and ≤70% diameter stenosis non-culprit vessel in the proximal-middle segments of RCA, LCX, LAD (the proximal and distal plaque within 5mm, same as below);
  • Radiography diameter of target vessel, 2.5-4.0mm;
  • Studied vessel can be evaluated with OCT and IVUS; OCT: the visual target study lesion is lipid-rich plaque with lipid arc≥100 degree and fiber cap thickness≤120µm.

You may not qualify if:

  • Life expectancy is less than 1 year;
  • Cannot implant drug stent;
  • Received ≥4weeks systematic treatment of statin and other lipid-lowering drug in the 3 months before admission;
  • Received ≥4 weeks systematic treatment of any traditional Chinese medicine;
  • Known to have adverse reaction to ingredients of NXT capsule;
  • Patients with severe heart disease that CABG or selective PCI, heart transplantationSAVR/TAVR are required during the study(12 months);
  • LVEF\<40%;
  • Drug uncontrollable recurrent and highly symptomatic arrhythmia such as ventricular tachycaidia, atrial fibrillation with rapid ventricular rate and paroxysmal supraventricular tachycardia in the 3 months before ACS admission;
  • Known any stroke;
  • Other operations arranged during the study period (12 months);
  • Uncontrollable hypertension, defined as resting systolic BP≥180mmHg;
  • Clinical confirmed as statin intolerance;
  • Type I diabetes or type 2 diabetes that is not well controlled;
  • Moderate and severe renal dysfunction (defined as eGFR\<30ml/min/1.73m2);
  • Clinical confirmed liver disease or liver dysfunction (AST or ALT \>3\*ULN);
  • +10 more criteria
