Abstract：Objective To investigate the relationship between the new ST-T waves on precise new electrocardiogram(SaahECG) and critical lesion of coronary heart disease(CHD).Methods We selected 38 CHD patients as research objects who had been admitted into Xiamen Cardiovascular Hospital Affiliated to Xiamen University from June 2016 to September 2017. Coronary angiography indicated critical coronary artery lesions(about 70% of coronary artery stenosis) in them. Intravascular ultrasound(IVUS) inspection was performed to evaluate whether stent implantation was required. The research objects were scanned by SaahECG while Ri/Rt ratio was mapped and analyzed. The Ri/Rt ratio and IVUS results were statistically analyzed. Results For the patients with critical coronary artery lesions, it was found that Ri/ Rt ratio<1 if the plaque burden was less than 70% verified by IVUS and there was no necessity of further stent implantation; Ri/Rt ratio>1 if the plaque burden was over 70% evaluated by IVUS and there was need of further stent implantation.Conclusion SaahECG can scan, record and show the natural signals of new ST-T waveforms in human heart, which provides a new method for evaluating the need of further invasive interventional examination and therapy on patients with critical coronary lesions. The method is simple, convenient and noninvasive. It is expected to be a completely new body surface examination method for clinical diagnosis, disease assessment and treatment instruction.
