ABSTRACT
Objective: To investigate the efficacy of sodium creatine phosphate in the treatment of acute left heart failure caused by essential hypertension, and observe the changes of serum cytochrome C (Cyt C) and cardiotrophin-1 (CT-1). Methods: Seventy-three patients with essential hypertension complicated with acute left heart failure were randomly divided into the control group (n=35) and the observation group (n=38). The patients in the control group were given such treatment as oxygen uptake, diuresis, hypotension and dilatation of blood vessels. The patients in the observation group were given sodium creatine phosphate (1. 0mg, ivd, qd) on the basis of the control group. The changes of NYHA functional class, 6-minute walking distance and left ventricular ejection fraction (LVEF% ) before the treatment, 3 days and 7 days after the treatment were observed. The serum levels of NT-proBNP, ST2, Cyt C and CT-1 were measured by ELISA before the treatment and 3 days and 7 days after the treatment. Results: Compared with those be-fore the treatment, the cardiac function indices were improved after the treatment, and the levels of serum NT-proBNP, ST2, Cyt C and CT-1 all decreased (P<0. 05). Conclusion: Creatine sodium phosphate can effectively enhance the clinical efficacy in hypertension patients with acute left heart failure. The mechanism may be related to enhancing the energy metabolism of myocardial cells and reduc-ing cardiomyocyte apoptosis.
ABSTRACT
Objective To explore the clinical effect of non-invasive positive pressure ventilation(NPPV)for treatment of acute left heart failure after mitral valve replacement. Methods Sixty patients with acute left heart failure after mitral valve replacement in Xinxiang Central Hospital from April 2009 to August 2017 were selected. The patients were divided into control group and NPPV group,with 30 patients in each group. The patients in the control group were treated with double oxygen ab-sorption (mask and nasal catheter),strong heart,diuresis and dilated blood vessels. Based on the treatment of control group, the patients in NPPV group were treated with NPPV therapy. The plasma N-terminal pro-B-type natriuretic peptide(NT-proB-NP)level of patients in the two groups was monitored by rapid determination of immunofluorescence before treatment and 6,24 hours after treatment. The respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure monitoring of patients in the two groups was monitored before treatment and 2,6 and 24 hours after treatment. Results The total effective rate of patients in the control group and NPPV group was 92. 4％(26 / 28)and 96. 6％(28 / 29)respectively;there was no sig-nificant difference in the total effective rate between the two groups(χ2 = 1. 25,P > 0. 05). There was no significant difference in the plasma NT-proBNP level between the two groups before treatment (P > 0. 05);the level of NT-proBNP at 6,24 h after treatment was significantly lower than that before treatment in the two groups (P < 0. 05);the level of NT-proBNP of patients in the NPPV group was significantly lower than that in the control group at 6,24 h after treatment (P < 0. 05). There was no significant difference in the respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure between the two groups before treatment(P > 0. 05). Compared with before treatment,the respiratory frequency and heart rate of patients were decreased and the blood oxygen saturation,oxygen partial pressure were increased at 2,6,24 h after treatment in the two groups (P < 0. 05). There was no significant difference in the oxygen partial pressure between the two groups at 2 h after treat-ment(P > 0. 05);the oxygen partial pressure of patients in the NPPV group was significantly higher than that in the control group at 6,24 h after treatment(P < 0. 05);there was no significant difference in the respiratory frequency,blood oxygen satu-ration and heart rate between the two groups at each time piont after treatment(P > 0. 05). Conclusion NPPV is an effective treatment for acute left heart failure after mitral valve replacement.
ABSTRACT
[Objective] The present study was to evaluate the association of serum total cholesterol level and prognosis in patients with acute left heart failure and associated mechanisms.[Methods] Sixty-eight patients due to acute episode of left heart failure prospectively enrolled,and baseline data and biochemical parameters were collected.After discharge,patients were follow-up for 1 month and they were divided into two groups (with and without cardiovascular events).Differences between groups were evaluated and the association of serum total cholesterol level and cardiovascular events were analyzed by logistic regression analysis.[Results] The mean age was 57.3 ± 12.6 years old and 52 cases were male patients accounting for 76.5 ％.Among these patients,46 had a diagnosis of coronary heart disease (67.6 ％),10 rheumatic heart disease (14.7 ％),12 dilated cardiomyopathy (17.7％),38hypertension (55.9％) and 24 diabetes mellitus (35.3％).After 1 month's follow up,39 patients (57.4％) had experienced cardiovascular events,36 cases were re-hospitalized,and 3 died from heart failure.Compared to those with cardiovascular events,event free individuals were younger and were less likely smokers (P ＜ 0.05).In addition,event free group had lower serum levels of N-terminal pro-BNP and C-reactive protein (P ＜ 0.05) while serum levels of total cholesterol and albumin were significantly higher (P ＜ 0.05).There was no significant difference in medication between these two groups.After adjusted for age,gender,smoking,systolic blood pressure,serum albumin level,diabetes,hypertension and medications,increased total cholesterol level was independently associated with better prognosis with odds ratio of 0.91 (95 ％ confidence interval 0.80-0.96).Further adjusted for C-reactive protein,the association was attenuated to non-significance,with odds ratio of 0.97 (95 ％ confidence interval 0.87-1.09).[Conclusion] Adequate serum total cholesterol level was beneficial for improving short-term cardiovascular outcomes in patients with left heart failure and the potential mechanisms might be related to cholesterol effects on improving nutritional status and anti-inflammation.

ABSTRACT
Objective To investigate the various occasions of invasive mechanical ventilation in patients with acute left heart failure. Methods Thirty-two patients with acute severe left heart failure were divided into two groups:17 patients were treated with non-invasive mechanical ventilation (non-invasive mechanical ventilation group) and 15 patients were treated with invasive mechanical ventilation (invasive mechanical ventilation group). The respiratory rate (RR), arterial oxy-gen partial pressure p(O2), heart rate (HR) and mean arterial pressure (MAP) were observed after treatment for 0.5 h,1 h and 3 h in two groups of patients. The in-hospital mortality was compared between two groups. Results Ten patients of non-in-vasive mechanical ventilation group were in remission after 0.5 h, 7 cases without remission switched to endotracheal intuba-tion for invasive mechanical. And 3 of them were in remission in 0.5~1 h, 4 of them dead. Fourteen patients in invasive me-chanical ventilation group were in remission after 0.5 h, one case was in remission after 0.5~1 h and no dead in this group. There were more patients in remission after 0.5 h in invasive mechanical ventilation group than those of non-invasive me-chanical ventilation group (P=0.041). There were no significant differences in the number of patients in clinical remission af-ter 0.5~1 h and mortality between two groups. The values of RR and HR were decreased with the increasing treatment time in two groups. The values of p(O2) and MAP were increased with the increasing treatment time in two groups. There was a sig-nificantly lower RR at 0.5 h and 1 h in invasive mechanical ventilation group than that of non-invasive mechanical ventila-tion group (P ＜ 0.05). The values of p(O2) and MAP were significantly higher at 0.5 h in invasive mechanical ventilation group than those of non-invasive mechanical ventilation group (P＜0.05). The levels of HR at 0.5 h and 3 h were significant-ly lower in invasive mechanical ventilation group than those of non-invasive mechanical ventilation group ( P＜0.05). Con-clusion Invasive mechanical ventilation should be used as soon as possible if non-invasive mechanical ventilation can not alleviate the symptoms in patients more than 0.5 hours.

ABSTRACT
Objective To compare the therapeutic effects in respect of ventilatory response and the change of hemodynamics of two modes of mechanical ventilation [ proportional assist ventilation (PAV) vs.Bi-level positive airway pressure ventilation (BiPAP) ] on patients with acute cardiogenic pulmonary edema (ACPE).Methods Thirty-two patients diagnosed as ACPE were recruited from May 2008 to April 2009.After conventional therapy ( cardiotonic,diuretic,vasodilators,oxygen) were ineffective for half an hour,32 patients were randomly divided into three groups:control group ( 12 cases kept conventional treatment without mechanical ventilation),BiPAP group ( 12 cases were treated with BiPAP mode of non-invasive mechanical ventilation plus conventional treatment) and PAV group (8 cases were treated with PAV mode of non-invasive mechanical ventilation along with conventional treatment ).Results PaO2,RR and oxygenation index were improved significantly in three groups after 1 hour treatment ( P ＜ 0.05 ).While PaO2 and oxygenation index in noninvasive ventilation groups were higher than those in control group ( P ＜0.05 ).The time required for amelioration of dyspnea in noninvsaive ventilation groups was shorter than that in control group ( P ＜ 0.05 ).The peak airway pressure and the index of degree of comfort ( VAS score,auxiliary respiratory muscles score) in PAV group were lower than those in BiPAP group (P ＜ 0.05 ).Conclusions Both modes of noninvasive mechanical ventilations could improve the oxygenation and relief of dyspnea in patients with ACPE.PAV and BiPAP had the similar effect in patients with ACPE.The synchronization and comfort in PAV group were better than those in BiPAP group.The PAV mode of noninvasive mechanical ventilation was well accepted by patients with ACPE.
ABSTRACT
