Abstract:
Objective To study the correlation between characteristic parameters of photoplethysmography( PPG)and severity of coronary artery lesions.Methods Two hundred and twenty-six CHD patients who underwent CAG in our hospital from August 2018to November 2018were divided into single-vessel lesion group(n=55),double-vessel lesion group(n=74)and multi-vessel lesion group(n=97)according to their CAG.Their stiffness index(SI),crest time(CT),normalized crest time(NCT)and crest time ratio(CTR)were recorded by PPG and analyzed by correlation analysis.Results The SI was significantly different in single-vessel lesion group,double-vessel lesion group and multi-vessel lesion group(6.479±0.819m/s,6.692±1.051m/s and 6.943±1.096m/s,P=0.024).No significant difference was detected in CT,NCT and CTR among single-vessel lesion group,double-vessel lesion group and multi-vessel lesion group(P＞0.05).The SI was positively correlated with the severity of coronary artery lesions(r=0.162,P=0.015).Conclusion The SI is correlated with the severity of coronary artery lesions,which is of a certain value in predicting the severity of coronary artery lesions.
