Bayesian network Meta-analysis was performed to evaluate the efficacy and safety of different Chinese patent medicines in the treatment of dilated cardiomyopathy. The PubMed, EMbase, Cochrane Library, CNKI, Wanfang, and VIP were searched for the randomized controlled trial(RCT) from the inception to May 2023. The quality of the included RCT was evaluated by the Cochrane risk of bias assessment tool, and the data were analyzed by RStudio 3.6.3 calling the "gemtc" package. A total of 96 RCTs involving 8 452 patients, 11 Chinese patent medicines, and 8 outcome indicators were included. Network Meta-analysis is described as follows.(1)In terms of improving clinical total effective rate, except Yixinshu Capsules + conventional western medicine, Shexiang Baoxin Pills + conventional western medicine, and Xinshuai Mixture + conventional western medicine, the other Chinese patent medicines combined with conventional western medicine were superior to conventional western medicine alone, and Shenqi Yiqi Dropping Pills + conventional western medicine had the best effect.(2)In terms of improving left ventricular ejection fraction(LVEF), except Yixinshu Capsules + conventional western medicine and Shensong Yangxin Capsules + conventional western medicine, other Chinese patent medicines combined with conventional western medicine outperformed conventional western medicine alone, and Shexiang Baoxin Pills + conventional western medicine had the best effect.(3)In terms of reducing left ventricular end-diastolic dimension(LVEDD), Getong Tongluo Capsules + conventional western medicine, Xinshuai Mixture + conventional western medicine, Huangqi Mixture + conventional western medicine, Tongxinluo Capsules + conventional western medicine, Wenxin Granules + conventional western medicine, and Qili Qiangxin Capsules + conventional western medicine were better than conventional western medicine alone, and Wenxin Granules + conventional western medicine had the best effect.(4)There was no significant difference in reducing left ventricular end-systolic diameter(LVESD) between Chinese patent medicines combined with conventional western medicine and conventional western medicine alone.(5)In terms of improving 6-minute walking trail(6MWT), Yangxinshi Tablets + conventional western medicine, Yixinshu Capsules + conventional western medicine, Shenqi Yiqi Dropping Pills + conventional western medicine, Wenxin Granules + conventional western medicine, and Qili Qiangxin Capsules + conventional western medicine were superior to conventional western medicine alone, and Shenqi Yiqi Dropping Pills + conventional western medicine had the best effect.(6)In reducing brain natriuretic peptide(BNP), Xinshuai Mixture + conventional western medicine ourperformed conventional western medicine alone.(7)In reducing hypersensitive C-reactive protein(hs-CRP), Shenqi Yiqi Dropping Pills + conventional western medicine, Qili Qiangxin Capsules + conventional western medicine outperformed conventional western medicine alone, and Qili Qiangxin Capsules + conventional western medicine had the best effect.(8)In terms of safety, adverse reactions were reported in both groups. In conclusion, Chinese patent medicine combined with conventional western medicine were more effective in the treatment of dilated cardiomyopathy. The combinations relieve clinical symptoms and improve cardiac function indexes, and thus can be used according to the patients' conditions in clinical practice. However, limited by the quality and sample size of the included studies, the conclusion remains to be verified by multi-center, large-sample, and high-quality RCT in the future.

BACKGROUND AND OBJECTIVES: Aortic valve replacement (AVR) is the treatment of choice in severe symptomatic aortic stenosis (AS) patients. However, a substantial number of elderly patients refuse AVR and treated medically. We investigated their long-term prognosis. METHODS: From January 2005 to December 2016, we analyzed elderly patients with severe symptomatic AS who refused to have AVR. RESULTS: After screening of total 534 patients, we analyzed total 180 severe symptomatic AS patients (78±7 years old, 96 males). Hypertension was the most common cardiovascular risk factor (72%) and the most common symptom was dyspnea (66%). Calculated aortic stenosis area was 0.73±0.20 cm2 and mean left ventricular ejection fraction (LVEF) was 57.8±12.2%. Total 102 patients died during follow-up period (39.1±31.0 months). One-, 3-, and 5-year all-cause mortality rate was 21.1±3.0%, 43.1±3.8%, and 56.5±4.2%, respectively. Of them, 87 died from cardiac causes, and 1-, 3-, and 5-year cardiac mortality rate was 18.0±2.9%, 38.2±3.8%, and 50.7±4.3%, respectively. Their all-cause mortality and cardiac mortality were significantly higher than those of controls. Univariate analysis showed that age, anemia, LVEF, and Log N-terminal pro B-type natriuretic peptide (NT-proBNP) were significant parameters in all-cause mortality (p < 0.001, p=0.001, p=0.039, and p=0.047, respectively) and in cardiac mortality (p < 0.001, p < 0.001, p=0.046, and p=0.026, respectively). Multivariate analysis showed that age and anemia were significant prognostic factors for cardiac and all-cause mortality. CONCLUSIONS: In elderly severe symptomatic AS patients who treated medically, their 1-, 3- and 5-year all-cause mortality rate was 21.1±3.0%, 43.1±3.8%, and 56.5±4.2%, respectively. Age and anemia were significant prognostic factors for cardiac and all-cause mortality.

BACKGROUND: Patients with acute respiratory failure secondary to tuberculous destroyed lung (TDL) have a poor prognosis. The aim of the present retrospective study was to develop a mortality prediction model for TDL patients who require mechanical ventilation. METHODS: Data from consecutive TDL patients who had received mechanical ventilation at a single university-affiliated tertiary care hospital in Korea were reviewed. Binary logistic regression was used to identify factors predicting intensive care unit (ICU) mortality. A TDL on mechanical Ventilation (TDL-Vent) score was calculated by assigning points to variables according to β coefficient values. RESULTS: Data from 125 patients were reviewed. A total of 36 patients (29%) died during ICU admission. On the basis of multivariate analysis, the following factors were included in the TDL-Vent score: age ≥65 years, vasopressor use, and arterial partial pressure of oxygen/fraction of inspired oxygen ratio <180. In a second regression model, a modified score was then calculated by adding brain natriuretic peptide. For TDL-Vent scores 0 to 3, the 60-day mortality rates were 11%, 27%, 30%, and 77%, respectively (p<0.001). For modified TDL-Vent scores 0 to ≥3, the 60-day mortality rates were 0%, 21%, 33%, and 57%, respectively (p=0.001). For both the TDL-Vent score and the modified TDL-Vent score, the areas under the receiver operating characteristic curve were larger than that of other illness severity scores. CONCLUSION: The TDL-Vent model identifies TDL patients on mechanical ventilation with a high risk of mortality. Prospective validation studies in larger cohorts are now warranted.

OBJECTIVES: Simvastatin has been reported to attenuate the development of pulmonary hypertension through increased apoptosis as well as reduced proliferation of smooth muscle cells in obstructive vascular lesions. Microarray experiment can accomplish many genetic tests in parallel. The purpose of this study is to evaluate altered expressions of gene in rat hearts with monocrotaline (MCT)-induced pulmonary arterial hypertension after simvastatin treatment. METHODS: Six-week-old male rats were grouped as follows: control group (C group, saline injection), M group (MCT 60 mg/kg), and S group (MCT 60 mg/kg plus 10 mg/kg/day simvastatin by gavage during 28 days). Body weight, right ventricular pressure and right ventricular/left ventricle+septum ratio in each group were measured. The rats were sacrificed after 28 days. Total RNA was extracted from the rat heart tissue and microarray analysis was performed. RESULTS: Administration of simvastatin significantly inhibited the progression of right ventricular hypertrophy at day 28 in the S group than in the M group. Compared with the C group, MCT was associated with a significant difference in expression of genes related to biosynthesis and with the regulation of heart contraction rate. Simvastatin treatment resulted in a significantly changed expression of genes about the regulation of progression through cell cycle and system development compared to the M group. The expressions of nitric oxide synthase and brain natriuretic peptide were significantly decreased after simvastatin treatment. CONCLUSION: Administration of simvastatin exerted inhibitory effects on right ventricular hypertrophy during the development of MCT-induced pulmonary arterial hypertension in rats. Simvastatin changes the expression of genes associated with various functions.

BACKGROUND/AIMS: Fluid retention occurs in patients with heart failure, accounting for dyspnea. We investigated the diagnostic implication of body fluid status, assessed by bio-impedance analysis (BIA), in acute heart failure (AHF) among patients who presented with dyspnea. METHODS: A total of 100 patients who presented with dyspnea and suspected with AHF were analyzed in this study. We enrolled 50 AHF and 50 non-AHF patients discriminated through echocardiographic analysis and Framingham criteria and were matched by age and sex. Body composition was analyzed using a multifrequency BIA. RESULTS: AHF patients demonstrated higher extracellular water (ECW)/total body water (TBW) compared with non-AHF patients (0.412 ± 0.017 vs. 0.388 ± 0.023, p < 0.001). A significant difference of ECW/TBW between AHF patients and nonAHF patients was noted when the upper extremities, trunk, and lower extremities were analyzed (all p < 0.001, respectively). ECW/TBW was not different between patients with reduced ejection fraction (EF) and preserved EF along body compartments. The best cut-off value to predict AHF was > 0.412 at lower extremities with sensitivity and specificity of 0.780 and 0.960. The ECW/TBW of the lower extremities (ECW/TBWL) was correlated with log B-type natriuretic peptide (BNP) levels (r = 0.603, p < 0.001) and also improved the net reclassification improvement and integrated discriminated improvement when added to log BNP level. Multivariate analysis revealed that ECW/TBWL > 0.412 had an independent association with AHF patients (p = 0.011). CONCLUSIONS: The ECW/TBWL was higher in patients with dyspnea caused by AHF than their counterparts and demonstrated an independent diagnostic implication. It may be a promising marker to diagnose AHF at bedside.

BACKGROUNDThe success rate of resuscitation in cardiac arrest (CA) caused by pulmonary thromboembolism (PTE) is low. Furthermore, there are no large animal models that simulate clinical CA. The aim of this study was to establish a porcine CA model caused by PTE and to investigate the pathophysiology of CA and postresuscitation.

METHODSThis model was induced in castrated male pigs (30 ± 2 kg; n = 21) by injecting thrombi (10-15 ml) via the left external jugular vein. Computed tomographic pulmonary angiography (CTPA) was performed at baseline, CA, and return of spontaneous circulation (ROSC). After CTPA during CA, cardiopulmonary resuscitation (CPR) with thrombolysis (recombinant tissue plasminogen activator 50 mg) was initiated. Hemodynamic, respiratory, and blood gas data were monitored. Cardiac troponins T, cardiac troponin I, creatine kinase-MB, myoglobin, and brain natriuretic peptide (BNP) were measured by enzyme-linked immunosorbent assay. Data were compared between baseline and CA with paired-sample t-test and compared among different time points for survival animals with repeated measures analysis of variance.

RESULTSSeventeen animals achieved CA after emboli injection, while four achieved CA after 5-8 ml more thrombi. Nine animals survived 6 h after CPR. CTPA showed obstruction of the pulmonary arteries. Mean aortic pressure data showed occurrence of CA caused by PTE (Z = -2.803, P = 0.002). The maximal rate of mean increase of left ventricular pressure (dp/dtmax) was statistically decreased (t = 6.315, P = 0.000, variation coefficient = 0.25), and end-tidal carbon dioxide partial pressure (PetCO2) decreased to the lowest value (t = 27.240, P = 0.000). After ROSC (n = 9), heart rate (HR) and mean right ventricular pressure (MRVP) remained different versus baseline until 2 h after ROSC (HR, P = 0.036; MRVP, P = 0.027). Myoglobin was statistically increased from CA to 1 h after ROSC (P = 0.036, 0.026, 0.009, respectively), and BNP was increased from 2 h to 6 h after ROSC (P = 0.012, 0.014, 0.039, respectively).

CONCLUSIONSWe established a porcine model of CA caused by PTE. The dp/dtmaxand PetCO2may be important for the occurrence of CA, while MRVP may be more important in postresuscitation.

BACKGROUND: Amino-terminal pro-B type natriuretic peptide (NT-proBNP) is a well-established prognostic factor in heart failure (HF). However, numerous causes may lead to elevations in NT-proBNP, and thus, an increased NT-proBNP level alone is not sufficient to predict outcome. The aim of this study was to evaluate the utility of two acute response markers, high sensitivity C-reactive protein (hsCRP) and heart-type fatty acid binding protein (H-FABP), in patients with an increased NT-proBNP level. METHODS: The 278 patients were classified into three groups by etiology: 1) acute coronary syndrome (ACS) (n=62), 2) non-ACS cardiac disease (n=156), and 3) infectious disease (n=60). Survival was determined on day 1, 7, 14, 21, 28, 60, 90, 120, and 150 after enrollment. RESULTS: H-FABP (P<0.001), NT-proBNP (P=0.006), hsCRP (P<0.001) levels, and survival (P<0.001) were significantly different in the three disease groups. Patients were divided into three classes by using receiver operating characteristic curves for NT-proBNP, H-FABP, and hsCRP. Patients with elevated NT-proBNP (≥3,856 pg/mL) and H-FABP (≥8.8 ng/mL) levels were associated with higher hazard ratio for mortality (5.15 in NT-proBNP and 3.25 in H-FABP). Area under the receiver operating characteristic curve analysis showed H-FABP was a better predictor of 60-day mortality than NT-proBNP. CONCLUSIONS: The combined measurement of H-FABP with NT-proBNP provides a highly reliable means of short-term mortality prediction for patients hospitalized for ACS, non-ACS cardiac disease, or infectious disease.

OBJECTIVETo study the value of Pentraxin 3 (PTX3) in diagnosing the severity and cardiovascular function of the critically ill children. Method A total of 178 patients who were older than 28 days, with acute infection of respiratory or neurological system, excluding chronic or special disease, and admitted to the pediatric intensive care unit (PICU) of Hunan Children's Hospital from October 1, 2013 to April 30, 2014 were enrolled, including 102 male cases and 76 female cases. The ages ranged from 1 month to 13 years and 1 month, 78 of them were less than 1 year old ; 58 cases were between 1 to 3 years old; 42 cases were above 3 years old; 101 cases were diagnosed as respiratory system diseases, 77 cases had nervous system diseases. PTX3 was detected with enzyme-linked immunosorbent assay (ELISA) within 1 d after enrollment, at 3 days and 7 days, meanwhile, troponin, myocardial enzyme, brain-type natriuretic peptide (BNP), C-reactive protein (CRP), plasma calcitonin (PCT) and WBC etc. Were measured. According to the plasma PTX3 value which were measured within 24 h after enrollment the patients were divided into three groups: mildly elevated group (< 44 µg/L) 41 cases; moderately elevated group (44 - < 132 µg/L) in 66 cases; severely elevated group 71 cases (132 µg/L or higher). Those 178 patients were divided into 3 groups according to the degree of infection: non-sepsis group (78 cases), sepsis group (70 cases), severe sepsis group (30 cases), and in each group, those with heart failure were respectively 19 cases, 28 cases, 17 cases. Analysis of the plasma PTX3 expression changes in different clinical manifestations, different condition, different degrees of organ damages and prognosis for the patient. The continuous variables were analyzed with t-test, F-test, H-test, the categorical variables were analyzed with Chi-square test, and the correlation analysis was performed to calculate Pearson coefficients.

RESULTThe PTX3 value measured within 24 h after enrollment increased with the degree of infection (50. 4(35. 2,70. 4) µg/L; 175. 8 (99. 6, 309. 9) µg/L;419. 9 (168. 3, 468. 6) µg/L; H = 88. 345, P = 0. 000). PTX3 level gradually declined, while in severe sepsis group decreased slowly (P <0. 05); the area under the ROC curve of Plasma PTX3 was larger than that of other inflammatory markers such as CRP and PCT, white blood cells and neutrophils in the diagnosis of sepsis; while the former three are PTX3, PCT and CRP (the sensitivity and specificity respectively were 0. 77, 0. 68; 0. 66, 0. 6; 0. 47, 0. 55); the PTX3 value of the severely elevated group was significantly higher than those of the mildly and moderately elevated groups (P <0. 05). The proportion of having 3 or more organs failure increased as the PTX3 rising among the groups of mildly elevated group, moderately elevated group and severely elevated group (1(2. 4%), 4(6. 1%), 14(19. 7%) χ2 =16. 16,P = 0. 000); and in each group, the proportion of having good and poor prognosis for these three groups were different (33 (80.5%) and 8 (19. 5%), 35 (53%) and 31 (47%), 28 (39.4%) and 43 (60.6%), χ = 17. 663, P = 0. 000). The K-M curve for these three groups had statistically significant difference (χ2 = 7. 086, P = 0. 029). Those with heart failure had higher PTX3 value than those in non-heart failure at the same degree of infection. PTX3 value increased with myocardial enzyme (troponin, creatine kinase isoenzyme, BNP) levels. In the diagnosis of heart failure, the area under the ROC curve were respectively PTX3 0. 824; BNP 0. 772; CM-KB 0. 643; CNTIO. 671, the sensitivity and specificity were PTX3 0. 8, 0. 58; CK-MB 0. 56,0. 79; CTNI 0. 60,0. 69; BNP 0. 73, 0. 58. In terms of predicting the prognosis of sepsis with heart failure complications, the PTX3 value's area under ROC curve was larger than that of BNP (respectively 0. 844, 0. 472).

CONCLUSIONThe PTX3 is an objective biochemical marker in diagnosis of sepsis; it is helpful in assessment of severity and prognosis of sepsis; it also has a certain clinical value in the assessment of sepsis cardiovascular function damage.

OBJECTIVE: Post-contrast T1 values are closely related to the degree of myocardial extracellular space expansion. We determined the relationship between post-contrast T1 values and left ventricular (LV) diastolic function, LV remodeling, and neurohormonal activation in patients with dilated cardiomyopathy (DCM). MATERIALS AND METHODS: Fifty-nine patients with DCM (mean age, 55 +/- 15 years; 41 males and 18 females) who underwent both 1.5T magnetic resonance imaging and echocardiography were enrolled. The post-contrast 10-minute T1 value was generated from inversion time scout images obtained using the Look-Locker inversion recovery sequence and a curve-fitting algorithm. The T1 sample volume was obtained from three interventricular septal points, and the mean T1 value was used for analysis. The N-Terminal pro-B-type natriuretic peptide (NT-proBNP) level was measured in 40 patients. RESULTS: The mean LV ejection fraction was 24 +/- 9% and the post-T1 value was 254.5 +/- 46.4 ms. The post-contrast T1 value was significantly correlated with systolic longitudinal septal velocity (s'), peak late diastolic velocity of the mitral annulus (a'), the diastolic elastance index (Ed, [E/e']/stroke volume), LV mass/volume ratio, LV end-diastolic wall stress, and LV end-systolic wall stress. In a multivariate analysis without NT-proBNP, T1 values were independently correlated with Ed (beta = -0.351, p = 0.016) and the LV mass/volume ratio (beta = 0.495, p = 0.001). When NT-proBNP was used in the analysis, NT-proBNP was independently correlated with the T1 values (beta = -0.339, p = 0.017). CONCLUSION: Post-contrast T1 is closely related to LV remodeling, diastolic function, and neurohormonal activation in patients with DCM.

OBJECTIVETo evaluate the predictive value of serum iron level for in-hospital acute heart failure (AHF) after acute ST-elevated myocardial infarction (STEMI).

METHODSThis retrospective study involved 287 patients with STEMI stratified by quartiles of admission serum iron concentration. The incidence of AHF was assessed by serum iron quartiles. We evaluated the association of serum iron levels with B-type natriuretic peptide (BNP), cardiac troponin I (cTnI), and high-sensitivity C-reactive protein (hs-CRP) levels on admission, and analyzed the correlation of serum iron levels with in-hospital AHF, death, and duration of hospital stay.

RESULTSThe average serum iron level on admission of the 287 STEMI patients was 10.20 µmol/L (6.90-14.40 µmol/L), and the quartiles (Q) of serum iron levels were ≤6.90 µmol/L (Q(1)), 6.91-10.19 µmol/L (Q(2)), 10.20-14.39 µmol/L (Q(3)), and ≥14.40 µmol/L (Q(4)). The incidences of in-hospital AHF from Q(1) to Q(4) were 79.5%, 64.3%, 50.0% and 45.9%, respectively (P<0.001). Univariate logistic regression analysis showed that low admission serum iron level (Q(1)) was an independent predictor for in-hospital AHF (OR=3.358, 95%CI 1.791- 6.294, P<0.001), and multivariate logistic regression analysis showed a similar result (OR=2.316, 95%CI 1.205-4.453, P=0.012).

CONCLUSIONSA lower admission serum iron level is an independent predictor of AHF in STEMI patients during hospitalization.
