NCT02692508

Brief Summary

The investigators sought to evaluate the morphological and functional changes and prognosis of participants with unexplainable precordial deep T-wave inversion on ECG and with apical thickness less than 15mm. The conduction of this study was largely due to the increased clinical requirement, which reflected the increased awareness among physicians of missed AHCM.

Study Population

subjects with unexplainable precordial deep T-wave inversion on ECG and with apical thickness less than 15mm

You may qualify if:

  • Standard 12-lead electrocardiography showing deep T-wave inversion, most prominent in the anterolateral leads (V3-V5 leads) with the negative T wave voltage ≥5mm.
  • Without evidence of coronary artery disease, or diameter stenosis ≥50% in one or more coronary vessels.
  • Asymmetrical LV hypertrophy confined to the LV apex below the papillary muscle level; end-diastolic apical wall thickness \<15mm with the apical to basal posterior wall thickness ratio \<1.5.

You may not qualify if:

  • Subjects who were not in sinus rhythm;
  • Patients with T-wave inversion in ≤ 2 contiguous leads, concomitant bundle branch block or QRS\>80 ms or QTC\>440 ms were excluded.
  • Blood pressure ≥140/90mmHg.
  • Severe valvular lesion, pericardial disease, cardiac tumor, immunological or metabolic disease involving heart.
  • History of cardiac surgery.
