- Abstract: Objective To provide more objective reference in diagnosis and prognosis of coronary heart disease(CHD)combined with heart failure(HF)by analyzing features of pulse graph parameters improved with moving average line method of patients with CHD combined with HF.Methods From September 2018 to December 2020,a random sampling method was used to collect 78 inpatients with CHD and 73 inpatients with CHD combined with HF in department of cardiology of Shu Guang Hospital Attached to Shanghai TCM University,Shanghai Municipal Hospital of Traditional Chinese Medicine and Yueyang Hospital of Integrated Traditional Chinese and Western Medicine,Shanghai University of Traditional Chinese Medicine as well as 78 healthy people from physical examination center of Shu Guang Hospital Attached to Shanghai TCM University and Yueyang Hospital of Integrated Traditional Chinese and Western Medicine,Shanghai University of Traditional Chinese Medicine.Smart TCM-I type pulse digital acquisition analyzer was used to collect pulse samples.χ2 test,LSD test,Dunnett's T3 test and Kruskal Wallis test were used to analyze the differences of pulse graph parameters among the groups improved with moving average line method.Results ①Results of pulse graph parameters about chronaxy:Compared with those in healthy people,t5 of patients with CHD decreased significantly(P<0.01),t,t3,t5 of patients with CHD combined with HF increased significantly(P<0.01).Compared with those in patients with CHD,t5 of patients with CHD combined with HF increased significantly(P<0.01),t3 increased(P<0.05).②Results of pulse graph parameters about ratio of chronaxy:Compared with those in healthy people,t1/t,w/t,tf/4/t,tf/3/t4,tf/4/t4,tf/5/t4,tf/3/tmax,tf/4/tmax,tf/5/tmax,tf/6/tmax of patients with CHD decreased significantly(P<0.01),tmax/t,w/t4,tf/3/t,tf/5/t,tf/6/t,tf/6/t4 decreased(P<0.05),t0.8/tmax increased(P<0.05),w/t,t0.9/t,t0.8/t,tf/3/t,tf/4/t,tf/5/t,tf/6/t,tf/3/t4,tf/4/t4,tf/3/tmax,tf/4/tmax,tf/5/tmax,tf/6/tmax of patients with CHD combined with HF decreased significantly(P<0.01),t1/t,tmax/t,w/t4,t0.9/t4 decreased(P<0.05),t3/t4 increased significantly(P<0.01).Compared with those in patients with CHD,t0.9/tmax of patients with CHD combined with HF decreased significantly(P<0.01),t0.9/t,t0.8/tmax decreased(P<0.05),t3/t4 increased significantly(P<0.01).③Results of pulse graph parameters about amplitude:Compared with those in healthy people,h4 of patients with CHD decreased(P<0.05),h3,h4 of patients with CHD combined with HF decreased significantly(P<0.01).Compared with those in patients with CHD,h5 of patients with CHD combined with HF decreased significantly(P<0.01),h3 decreased(P<0.05).④Results of pulse graph parameters about ratio of amplitude:Compared with those in healthy people,h4/h1 of patients with CHD decreased(P<0.05),h3/h1,h4/h1 of patients with CHD combined with HF decreased significantly(P<0.01).Compared with those in patients with CHD,h5/h1 of patients with CHD combined with HF decreased significantly(P<0.01).Conclusion Patients with CHD combined with HF characterize a weakening arterial compliance and an increasing peripheral resistance.Their cardiac contractility is decreased with shorten rapid ejection phase.The myocardium is likely to remodel which leads to a slower heart rate and the decreased stroke volume may cause a low pulse pressure.Patients with CHD combined with HF are more likely to suffer from decreased function of aortic valve.The most common pulse conditions are infrequent pulse,uneven pulse,thready pulse,slippery pulse and taut pulse.Pulse graph parameters improved with moving average line method can provide more objective reference in studying features of pulse graph of CHD combined with HF.It is conducive to further promote the objectification of pulse diagnosis.
