OBJECTIVES

Clinical pathways (CPs) ensure adherence to heart failure (HF) management guidelines. To optimize quality care in a low resource setting, an evidence-based care pathway for the management of acute HF was implemented at the emergency department (ED) of the Philippine General Hospital (PGH), the designated national tertiary hospital and referral center. This study aimed to describe the characteristics of adults with acute HF admitted at the ED and evaluate the quality of care they received, measured using physician adherence to the hospital’s acute heart failure CP.

METHODS

This was a retrospective, descriptive cohort study. We reviewed the inpatient charts of all adult patients with acute HF admitted to the ED of the PGH and referred to the Division of Cardiovascular Medicine between December 1, 2022 and May 31, 2023. Quality of care was assessed based on adherence to quality indicators adapted from routine and conditional order sets detailed in the pathway. Descriptive statistics was utilized to describe patient characteristics, quality of care, and outcomes.

RESULTS

Two hundred thirty-six (236) patients were included, with a mean age of 51.8 years. Majority were male (53.4%); hypertension (61.4%) and ischemic heart disease (53.8%) were the most common comorbidities, and infection the most common precipitant of decompensation (60.6%). There were optimal adherence rates to routine orders, which included referrals to Internal Medicine and Cardiology, baseline vital signs monitoring, fluid intake and output monitoring, chest radiograph, complete blood count, blood urea nitrogen, sodium, potassium, prothrombin time, partial thromboplastin time, arterial blood gas, urinalysis, and N-terminal pro b-type natriuretic peptide. Conditional orders, such as oxygen support, focused echocardiography, thyroid - stimulating hormone, and the use of vasopressors, diuretics, and venous thromboembolism prophylactic agents, were optimally performed when warranted. However, we noted suboptimal adherence to certain resource-intensive conditional orders, such as hourly monitoring of urine output (61.4%), hooking to cardiac monitor (53.8%), and performance of 12-lead ECG within 10 minutes (56.8%). Further, only 43.9% of patients were referred to the intensive care unit. Troponin I, calcium, magnesium, and albumin were ordered in excess.

CONCLUSION

Overall adherence rate of physicians to the hospital’s Acute Heart Failure Pathway was satisfactory. Work is needed to improve adherence to hourly urine output monitoring, consistent hooking to cardiac monitor, and timely performance of 12-lead ECG – an effort that begins with expanding in-hospital diagnostic equipment and human resource supply. We recommend continuous pathway implementation with periodic evaluation and stakeholder feedback to further improve quality of care.

OBJECTIVE: To investigate the efficacy and safety of autologous blood transfusion during weaning from venous-arterial extracorporeal membrane oxygenation (VA-ECMO) under controlled rotational speed. METHODS: A retrospective study was conducted, selecting patients who underwent extracorporeal membrane oxygenation (ECMO) and successfully weaned at the emergency and critical care medicine center of Henan Provincial Third People's Hospital from January 2023 to May 2024. General data including gender, age, body mass index (BMI), European system for cardiac operative risk evaluation (EuroScore), and disease types were collected. Vital signs at weaning [heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and peripheral oxygen saturation], parameters before and after weaning [B-type natriuretic peptide (BNP), hemoglobin (Hb), partial pressure of arterial oxygen (PaO₂), partial pressure of arterial carbon dioxide (PaCO₂), arterial lactate, central venous pressure (CVP), inferior vena cava collapsibility index, left ventricular ejection fraction (LVEF), and right heart load], post-weaning inflammatory markers at 1-day and 3-day [body temperature, white blood cell count (WBC), neutrophil percentage (NEU%), C-reactive protein (CRP), procalcitonin (PCT), interleukin-10 (IL-10)], as well as complications (infection, thrombosis, renal failure, gastrointestinal bleeding) and post-weaning blood return status were recorded. Patients were divided into an observation group (with post-weaning blood return) and a control group (without post-weaning blood return) based on the presence of blood return after weaning. The changes in the aforementioned parameters were compared between the two groups. RESULTS: A total of 62 patients were included, with 31 cases in each group. No statistically significant differences were observed between the two groups in baseline characteristics including gender, age, BMI, and EuroScore. At weaning, the observation group exhibited relatively stable vital signs, with no significant differences in heart rate, SBP, DBP, or peripheral oxygen saturation compared to the control group. After weaning, the observation group showed significantly lower levels of BNP, PaCO₂, arterial lactate, CVP, and right heart load compared to pre-weaning values [BNP (ng/L): 2 325.96±78.51 vs. 4 878.48±185.47, PaCO₂ (mmHg, 1 mmHg≈0.133 kPa): 35.23±3.25 vs. 40.75±4.41, arterial lactate (mmol/L): 2.43±0.61 vs. 6.19±1.31, CVP (cmH₂O, 1 cmH₂O≈0.098 kPa): 8.32±0.97 vs. 15.34±1.74, right heart load: 13.24±0.97 vs. 15.69±1.31, all P < 0.05], while Hb, PaO₂, inferior vena cava collapsibility index, and LVEF were significantly higher than pre-weaning values [Hb (g/L): 104.42±9.78 vs. 96.74±6.39, PaO₂ (mmHg): 94.12±7.78 vs. 75.51±4.39, inferior vena cava collapsibility (%): 28±7 vs. 17±3, LVEF (%): 62.41±6.49 vs. 45.30±4.51, all P < 0.05]. No statistically significant differences were found between the observation group and control group in these parameters. At 3 days post-weaning, the observation group demonstrated significantly lower levels of body temperature, WBC, NEU%, CRP, PCT, and IL-10 compared to 1 day post-weaning [body temperature (centigrade): 36.83±1.15 vs. 37.94±1.41, WBC (×10⁹/L): 7.82±0.96 vs. 14.34±2.15, NEU%: 0.71±0.05 vs. 0.80±0.07; CRP (mg/L): 4.34±0.78 vs. 8.94±1.21, PCT (μg/L): 0.11±0.02 vs. 0.26±0.05, IL-10 (ng/L): 8.93±1.52 vs. 13.51±2.17, all P < 0.05], with no significant differences compared to the control group. No statistically significant differences were observed between the two groups in the incidence of complications including infection, thrombosis, renal failure, and gastrointestinal bleeding. CONCLUSION Autologous blood reinfusion during VA-ECMO weaning under controlled rotational speed is safe and effective, without increasing risks of infection or thrombosis.

Astragali Radix (AR) and Notoginseng Radix et Rhizoma (NR) are frequently employed in cardiovascular disease treatment. However, the efficacy of the AR-NR medicine pair (AN) in improving cardiac remodeling and its underlying mechanism remains unclear. This study aimed to evaluate AN's cardioprotective effect and potential mechanism on cardiac remodeling using transverse aortic constriction (TAC) in mice and angiotensin II (Ang II)-induced neonatal rat cardiomyocytes (NRCMs) and fibroblasts in vitro. High-performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (HPLC-Q-TOF-MS/MS) characterized 23 main components of AN. AN significantly improved cardiac function in the TAC-induced mice. Furthermore, AN considerably reduced the serum levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), cardiac troponin T (CTn-T), and interleukin-6 (IL-6) and mitigated inflammatory cell infiltration. Post-AN treatment, TAC-induced heart size approached normal. AN decreased cardiomyocyte cross-sectional area and attenuated the upregulation of cardiac hypertrophy marker genes (ANP, BNP, and MYH7) in vivo and in vitro. Concurrently, AN alleviated collagen deposition in TAC-induced mice. AN also reduced the expression of fibrosis-related indicators (COL1A1 and COL3A1) and inhibited the activation of the transforming growth factor-β1 (TGF-β1)/mothers against decapentaplegic homolog 3 (Smad3) pathway. Thus, AN improved TAC-induced cardiac remodeling. Moreover, AN downregulated p-dynamin-related protein (Drp1) (Ser616) expression and upregulated mitogen 2 (MFN-2) and optic atrophy 1 (OPA1) expression in vivo and in vitro, thereby restoring mitochondrial fusion and fission balance. In conclusion, AN improves cardiac remodeling by regulating mitochondrial dynamic balance, providing experimental data for the rational application of Chinese medicine prescriptions with AN as the main component in clinical practice.

Ambient air pollution is increasingly being recognized as a risk factor for heart failure; however, its effects on cardiac biomarkers remain unclear. This scoping review assessed the existing evidence on the association between air pollution and cardiac biomarkers in heart failure, described the key concepts, synthesized data, and identified research gaps. Following the PRISMA-ScR guidelines, PubMed, Embase, Web of Science, and CNKI databases were searched for studies on air pollution, heart failure, and biomarkers. A total of 765 records were screened, and 81 full texts were assessed for eligibility, resulting in 15 studies. The results showed that the exposure to particulate matter was associated with elevated N-terminal pro-B-type natriuretic peptide and troponin levels. Several studies have linked particulate matter exposure to a higher cardiovascular risk and heart failure biomarkers. Inflammatory and oxidative stress markers were consistently elevated across studies, supporting the biological relevance of these associations. However, few studies have focused specifically on populations with heart failure or clinically relevant biomarkers, and the evidence for gaseous pollutants remains inconclusive. These findings highlight the need to integrate environmental risk assessment into heart failure care and inform policy efforts to reduce the pollution-related cardiovascular burden. Further research should address these gaps through improved exposure assessments and the integration of mechanistic evidence.

BACKGROUND: Changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels may not fully translate into patient-reported health status in patients with heart failure (HF). We aimed to evaluate the correlation between NT-proBNP levels and patient-reported health status changes at one month after discharge of patients, and their associations with risk of death and rehospitalization in patients with acute HF. METHODS: We used data from the China Patient-centered Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (PEACE 5p-HF Study). Patient-reported health status was measured by the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Patients who were hospitalized for HF and completed the KCCQ-12 and NT-proBNP tests before and one month after discharge were eligible in our study. We stratified patients into different groups based on NT-proBNP levels (i.e., improved, stable, and deteriorated) and KCCQ-12 scores (i.e., not deteriorated and deteriorated). We also examined the associations of the joint NT-proBNP and KCCQ-12 change with the risk of one-year and four-year clinical outcomes. RESULTS: A total of 2461 patients were included in the analysis. The mean age was 64.06 ± 13.51 years, and 36.37% (895/2461) of the study population were female. Among patients with improved NT-proBNP levels, 115 (10.95%) patients had deteriorated KCCQ-12 scores. The correlation between the change in the KCCQ-12 score and NT-proBNP level was weak ( r2 = 0.002, P = 0.013). Stratification by changes in the KCCQ-12 score revealed subgroups with distinctive risks, such that patients with deteriorated KCCQ-12 scores in any of the NT-proBNP change groups exhibited an increased risk of one-year all-cause death than participants with not deteriorated KCCQ-12 scores in any of the NT-proBNP change groups. Patients with improved NT-proBNP levels and deteriorated KCCQ-12 scores presented greater risks of one-year all-cause death (hazard ratio [HR]: 2.45, 95% confidence interval [CI]: 1.34-4.48) than patients with stable NT-proBNP levels and not deteriorated KCCQ-12 scores (HR [95% CI], 1.77 [1.25-2.53]). CONCLUSIONS: A discrepancy between changes in NT-proBNP levels and KCCQ-12 scores was common. The change in NT-proBNP levels was not sufficient to characterize critical aspects related to HF during one month after discharge of patients. Changes in the KCCQ-12 score exhibit complementary information to NT-proBNP levels for the prediction of clinical outcomes in patients with acute HF.

OBJECTIVES: Patients with heart failure with reduced ejection fraction (HFrEF) often require diuretics during hospitalization to alleviate fluid retention and improve prognosis. However, the diuretic efficacy and renal impact of dapagliflozin in this population remain unclear. This study aims to investigate the effects of dapagliflozin on diuresis and renal function in hospitalized patients with HFrEF. METHODS: This retrospective analysis included clinical data from 200 hospitalized HFrEF patients treated at Xiangya Hospital of Central South University between January 2021 and September 2022. Patients were divided into 2 groups based on whether they received dapagliflozin: a standard treatment group (n=120) and a dapagliflozin treatment group (n=80). The following were compared between the 2 groups during hospitalization: The 24-hour average difference of liquid intake and output during the first 5 days, urine output, cumulative urine output, diuretic efficiency, estimated glomerular filtration rate (eGFR), N-terminal pro B-type natriuretic peptide (NT-proBNP), hospitalization costs, drug costs, and cost-effectiveness ratio (C/E). RESULTS: 1) Primary outcome: The 24-hour average difference of liquid intake and output during the first 5 days was significantly higher in the dapagliflozin treatment group than in the standard treatment group (P<0.05). 2) Secondary outcomes: The 24-hour average urine volume, cumulative urine volume and diuretic efficiency in the first 5 days of dapagliflozin treatment group were higher than those in the standard treatment group, and the differences were statistically significant (all P<0.05). Among patients with impaired renal function on admission [eGFR between 45 and 90 mL/(min·1.73 m²)], the change in eGFR after treatment was significantly smaller in the dapagliflozin treatment group (P<0.05). For patients with normal renal function on admission [eGFR >90 mL/(min·1.73 m²)], the difference in eGFR changes between 2 groups was not significant (P>0.05). NT-proBNP decreased more in the dapagliflozin treatment group than in the standard treatment group during hospitalization (P<0.05). 3) Other indicators: The length of hospital stay was longer in the dapagliflozin treatment group. However, discharge systolic blood pressure, drug costs, and hospitalization costs were all higher in the standard group, though differences were not statistically significant (all P>0.05). The C/E was more favorable in the dapagliflozin treatment group (425.36 vs. 476.67). CONCLUSIONS In hospitalized patients with chronic HFrEF, dapagliflozin treatment increased 24-hour average difference of liquid intake and output and total urine output, reduced NT-proBNP levels, and showed a milder decline in eGFR in those with pre-existing renal impairment. Discharge blood pressure, drug costs, and hospital stay were not significantly affected. While standard therapy may offer better short-term clinical benefits, dapagliflozin demonstrated a superior short-term cost-effectiveness profile.

OBJECTIVE: To compare the effects on the heart rate variability (HRV) and the expression of the atrial natriuretic peptide (ANP) in the model rats of irritable bowel syndrome with predominant diarrhea (IBS-D) rats complicated with anxiety between moxibustion of "biaoben acupoint combination" and that of "conventional acupoint combination". METHODS: Of 50 healthy SPF female SD rats, aged 3 months, 8 rats were selected randomly as a blank group, and the rest rats were prepared to be the model of IBS-D complicated with anxiety. Twenty-four rats after successfully modeled were randomized into a model group, a conventional acupoint combination group (convention group) and a biaoben acupoint combination group (biaoben group), 8 rats in each one. In the convention group, moxibustion was delivered at "Tianshu" (ST 25), "Zusanli"(ST 36) and "Shangjuxu"(ST 37); and in the biaoben group, moxibustion was applied to "Neiguan" (PC 6), "Zusanli" (ST 36), and "Guanyuan" (CV 4). One session of moxibustion took 20 min, once daily, for 14 days in total. Before and after intervention, the body mass and fecal moisture content were compared in the rats of each group; using abdominal wall withdrawal reflex, the visceral hypersensitivity was evaluated; with elevated plus maze (EPM) and light-dark box (LDB), the anxiety conditions were assessed. After intervention, HRV was compared among groups, the ultrastructure of intestinal mucosa was observed under the transmission electron microscope in the rats of each group, and ANP expression in the myocardial tissue was detected using Western blot method and immunofluorescence. RESULTS: Before the intervention, compared with the blank group, the body mass and visceral pain threshold of rats were reduced in the model group, the convention group and the biaoben group (P<0.05), fecal moisture content and AWR scores (at the dilatation pressure of 40, 60 and 80 mm Hg, 1 mm Hg ≈ 0.133 kPa) were elevated (P<0.05); and time in the open arm, the open arm entry number and the total movement distance (EPM), the time spent in the light compartment, the number of dark to light transitions and the total transition distance (LDB) were decreased (P<0.05). After the intervention, compared with the blank group, in the model group, the body mass, visceral pain threshold, standard diviation of NN intervals (SDNN) and root mean square of successive RR interval differences (RMSSD) were dropped (P<0.05), fecal moisture content, AWR scores (the dilation pressures of 40, 60 and 80 mm Hg), LF/HF and ANP expression were increased (P<0.05), the time in open arm, the open arm entry number and the total movement distance (EPM), the time spent in the light compartment, the number of dark to light transitions and the total transition distance (LDB) were decreased (P<0.05). When compared with the model group, in the convention group and the biaoben group, the body mass, visceral pain threshold, SDNN and RMSSD were increased (P<0.05), fecal moisture content, AWR scores (the dilation pressures of 60 and 80 mm Hg), LF/HF and ANP expression were dropped (P<0.05), the time in open arm, the open arm entry number and the total movement distance (EPM), the time spent in the light compartment, the number of dark to light transitions and the total transition distance (LDB) were increased (P<0.05). In the biaoben group, compared with the convention group, the body mass, visceral pain threshold, SDNN and RMSSD were elevated (P<0.05), fecal moisture content, AWR score (the dilation pressure of 80 mm Hg), LF/HF and ANP expression were decreased (P<0.05), the time in open arm, the open arm entry number and the total movement distance (EPM), the time spent in the light compartment, the number of dark to light transitions and the total transition distance (LDB) were increased (P<0.05). The epithelial cells of the intestinal mucosa showed a normal morphology in the blank group, the tight junction of the cells was disrupted and the junction was loose in the model group; the tight junction was imperfect in the convention group, but it was intact in the biaoben group. CONCLUSION Compared with the conventional acupoint combination, moxibustion of biaoben acupoint combination is more effective on the symptoms of IBS-D complicated with anxiety in the model rats. The effect mechanism may be related to attenuating anxiety-like negative emotions, positively regulating HRV, stabilizing IBS-D intestinal mucosal barrier and down-regulating the expression of ANP in myocardium.

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.

The study aimed to evaluate the therapeutic effect of nilotinib-loaded biocompatible gelatin methacryloyl (GelMA) microneedles patch on cardiac dysfunction after myocardial infarction(MI), and provide a new clinical perspective of myocardial fibrosis therapies. The GelMA microneedles patches were attached to the epicardial surface of the infarct and peri-infarct zone in order to deliver the anti-fibrosis drug nilotinib on the 10th day after MI, when the scar had matured. Cardiac function and left ventricular remodeling were assessed by such as echocardiography, BNP (brain natriuretic peptide) and the heart weight/body weight ratio (HW/BW). Myocardial hypertrophy and fibrosis were examined by WGA (wheat germ agglutinin) staining, HE (hematoxylin-eosin staining) staining and Sirius Red staining. The results showed that the nilotinib-loaded microneedles patch could effectively attenuate fibrosis expansion in the peri-infarct zone and myocardial hypertrophy, prevent adverse ventricular remodeling and finally improve cardiac function. This treatment strategy is a beneficial attempt to correct the cardiac dysfunction after myocardial infarction, which is expected to become a new strategy to correct the cardiac dysfunction after MI. This is of great clinical significance for improving the long-term prognosis of MI patients.
