Abstract:
Objective To explore the follow-up value of phonocardiogram D/S ratio in CHF patients with treatment.Methods Forty-eight CHF patients who had never under-went regular treatment were collected in our hospital,given the regular anti-heart failure treatment for 3 months.NYHA heart failure classification,resting heart rate(RHR),and D/S ratio of phonocardiogram were recorded,six-minutes walk distance(6MWD),Left ventricular end diastolic diameter(LVEDd),the left ventricular ejection(LVEF) were tested before and after treatment.After 3-month treatment,the resting heart rate 65 times as the watershed,the patients were classified into two groups:one was up to standard,and the other was not up to standard.D/S ratio,RHR,6MWD,LVEDD,LVEF and the improvement of the heart function were compared between the two group.Results Exception the resting heart rate,the in-dicators had no significant improvement in the group of not up to standard compared with the before treatment,and D/S ratio, 6MWD,LVEF was improved significantly after three months treatment(P <0.05).In the group of up to standard,the D/S ratio was improved significantly after one months treatment(P <0.05),while after three months treatment all indicators were improved significantly(P <0.05).Comparison between the two groups,the RHR,D/S ratio were significantly improved(P <0.05 ),LVEF was significantly improved after three months treatment(P <0.05).At the same time,the D/S ratio,6MWD and NYHA classifica-tion of cardiac function was significant negatively correlated(P <0.05).Conclusion The D/S ratio could reflect heart functional im-provements in patients with CHF after anti-heart failure treatment,and it could reflect the heart functional improvement earlier and more significant in the group up to standard,it has a good clinic follow-up value in CHF patients with anti-heart failure treatment.
