Congestive heart failure is a complication of myocardial infarction threatening human health. Although the pharmacotherapy is effective, it is still a worldwide challenge to thoroughly repair the injured myocardium induced by myocardial infarction. It has been demonstrated that mesenchymal stem cells (MSCs) can repair infarcted myocardium. Much evidence shows that MSCs can generate new myocardial cells in both human and animals' hearts. This review aims at discussing the therapeutic progress of the congestive heart failure treated with MSCs.
Objective To systematically review the efficacy and safety of different SGLT2 inhibitors in the treatment of heart failure. Methods The Cochrane Library, Web of Science, PubMed and EMbase databases were searched for randomized controlled trials on the efficacy and safety of SGLT2 inhibitors in patients with heart failure from inception to July 2, 2021. Two researchers independently screened literature, extracted data and evaluated the risk of bias of the included studies. Network meta-analysis was then performed using Stata 16.0 software. Results A total of 16 randomized controlled trials, including 15 312 patients, involving 5 interventions, namely dapagliflozin, empagliflozin, canagliflozin, sotagliflozin and ertugliflozin were included. Results of network meta-analysis showed that there was no significant difference in the compound outcome of hospitalization for heart failure or cardiovascular death, hospitalization for heart failure, all-cause mortality, risk of cardiovascular mortality and serious adverse reactions among patients with heart failure among 5 different SGLT2 inhibitors (P>0.05). Compared with placebo, both selective and non-selective SGLT2 inhibitors improved the risk of hospitalization for heart failure, hospitalization for heart failure, or compound cardiovascular mortality (P<0.05), while only selective SGLT2 inhibitors improved the risk of cardiovascular mortality, all-cause mortality, and serious adverse events (P<0.05). However, there was no significant difference between them (P>0.05). The area under the cumulative ordering probability curve of selective and non-selective SGLT2 inhibitors ranked first and second, except for the combined outcome of heart failure or cardiovascular death. Conclusion The current evidence indicates that there is no significant difference in the efficacy and safety of the 5 different SGLT2 inhibitors in the treatment of heart failure, and there is no significant difference between selective SGLT2 inhibitors and non-selective SGLT2 inhibitors. Due to the limited quantity and quality of included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo summarize the individualized selection of surgical treatment strategies and the key points of perioperative management for patients with heart valve disease complicated with severe chronic heart failure.MethodsThe clinical characteristics of 5 male patients with valvular heart disease complicated with severe chronic heart failure (CHF) were analyzed retrospectively from June 2017 to October 2018 in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, with an average age of 60.21 years.ResultsFive patients were given angiotensin receptor and neprilysin inhibitor (ARNI)-based anti-heart failure treatment after admission. The operation mode of these patients was decided to be valve replacement under cardiopulmonary bypass after individualized evaluation of patients’ improving symptoms. Three patients were treated with intra-aortic balloon pump (IABP) and continuous renal replacement therapy (CRRT) early after operation to assist patients in improving cardiac function. Five patients recovered oral anti-heart failure after awakening. All patients were discharged smoothly 2 weeks after operation.ConclusionIndividualized evaluation is needed for the choice of operation timing and mode, standardized preoperative treatment for heart failure, shortening the aortic blocking time during cardiopulmonary bypass, and early application of left ventricular adjuvant drugs or instruments are all important measures to help patients recover smoothly.
ObjectiveTo systematically review the efficacy of Chinese medicine injection (CMI) for treating heart failure (HF).MethodsCNKI, WanFang Data, VIP, The Cochrane Library, PubMed, and EMbase databases were electronically searched from inception to January 2021 to identify randomized controlled trials (RCTs) on CMI for treating HF. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of included studies. Network meta-analysis was then performed by RevMan 5.2 software and Stata 16.0 software.ResultsA total of 47 studies were included involving 4 902 patients and 5 types of CMIs, including Shenmai, Shenfu, Yiqi Fumai (lyophilized), Shengmai, and Danhong injections. The results of network meta-analysis showed that the efficacy of combined CMIs was superior to conventional Western medicine alone. For the main efficacy, Shenmai, Shengmai, and Shenfu injections had significant advantages in improving the total clinical effectiveness. Shengmai, Shenmai, and Yiqi Fumai (lyophilized) injections were significantly more effective for reducing NT pro-BNP levels than other injections. Shenfu and Shengmai injections were significantly more effective for reducing BNP levels than other injections. Shenmai, Danhong and Shengmai injections were significantly more effective for improving the left ventricular ejection fraction than the other injections. These CMIs showed similar advantages for secondary efficacy indicators as for main efficacy indicators.ConclusionsThe combined 5 types of CMIs for treating HF can improve the clinical efficacy when compared with conventional Western medicine treatment. Shenmai injection, Yiqi Fumai injection (lyophilized), and Shengmai injection, which is part of Sheng Mai San, have clear advantages in terms of the overall curative effect or on individual indices.
Objective To evaluate the efficacy of recombinant human brain natriuretic peptide (rhBNP) on Chinese patients with congestive heart failure by meta analysis. Methods Both foreign language databases including PubMed, EMbase, The Cochrane Library (Issue 3, 2009) and Chinese databases involving CBM, VIP and CJFD were searched to identify randomized controlled trials (RCTs) that reported the effect of rhBNP on the heart function (left ventricular ejection fraction (LVEF) and the recent level of improvement in cardiac function) and its side effects of Chinese patients with congestive heart failure. Two reviewers assessed the quality of each trial and extracted data independently. The Cochrane Collaboration’s RevMan 4.2.8 software was used for statistical analysis. Results Nineteen RCTs were included, all of which came from internal. The methodological quality of the included studies was good. The baseline data of each trial were comparable. The results of meta-analyses showed: (1) the improvement of LVEF was higher in the rhBNP group than that in the blank control group (WMD=7.22, 95%CI 3.15 to 11.291, P=0.000 5). The level of improvement in cardiac function was better in the rhBNP group than those in the blank control group (OR=5.48, 95%CI 1.61 to 18.65, P=0.007), the nitroglycerin group (OR=3.60, 95%CI 2.02 to 6.41, Plt;0.000 1), and the sodium nitroprusside group (OR=3.21, 95%CI 0.12 to 85.20, P=0.49). The incidence of side effects was lower in the rhBNP group than that in the nitroglycerin group (OR=0.23, 95%CI 0.11 to 0.47, Plt;0.000 1), and the sodium nitroprusside group (OR=0.30, 95%CI 0.11 to 0.82, P=0.02). Moreover, the results of sensitivity analysis were also consistent with the above findings. Conclusion Recombinant human brain natriuretic peptide can effectively improve the hemodynamics and cardiac function level of Chinese population of patients with heart failure. The treatment doses are safe and tolerant, so it is recommended to clinical use.
Heart failure is a disease that seriously threatens human health and has become a global public health problem. Diagnostic and prognostic analysis of heart failure based on medical imaging and clinical data can reveal the progression of heart failure and reduce the risk of death of patients, which has important research value. The traditional analysis methods based on statistics and machine learning have some problems, such as insufficient model capability, poor accuracy due to prior dependence, and poor model adaptability. In recent years, with the development of artificial intelligence technology, deep learning has been gradually applied to clinical data analysis in the field of heart failure, showing a new perspective. This paper reviews the main progress, application methods and major achievements of deep learning in heart failure diagnosis, heart failure mortality and heart failure readmission, summarizes the existing problems and presents the prospects of related research to promote the clinical application of deep learning in heart failure clinical research.
Objective To systematically evaluate the prognostic prediction model for chronic heart failure patients in China, and provide reference for the construction, application, and promotion of related prognostic prediction models. Methods A comprehensive search was conducted on the studies related to prognostic prediction model for Chinese patients with chronic heart failure published in The Cochrane Library, PubMed, EMbase, Web of Science, CNKI, VIP, Wanfang, and the China Biological Medicine databases from inception to March 31, 2023. Two researchers strictly followed the inclusion and exclusion criteria to independently screen literature and extract data, and used the prediction model risk of bias assessment tool (PROBAST) to evaluate the quality of the models. Results A total of 25 studies were enrolled, including 123 prognostic prediction models for chronic heart failure patients. The area under the receiver operating characteristic curve (AUC) of the models ranged from 0.690 to 0.959. Twenty-two studies mostly used random splitting and Bootstrap for internal model validation, with an AUC range of 0.620-0.932. Seven studies conducted external validation of the model, with an AUC range of 0.720-0.874. The overall bias risk of all models was high, and the overall applicability was low. The main predictive factors included in the models were the N-terminal pro-brain natriuretic peptide, age, left ventricular ejection fraction, New York Heart Association heart function grading, and body mass index. Conclusion The quality of modeling methodology for predicting the prognosis of chronic heart failure patients in China is poor, and the predictive performance of different models varies greatly. For developed models, external validation and clinical application research should be vigorously carried out. For model development research, it is necessary to comprehensively consider various predictive factors related to disease prognosis before modeling. During modeling, large sample and prospective studies should be conducted strictly in accordance with the PROBAST standard, and the research results should be comprehensively reported using multivariate prediction model reporting guidelines to develop high-quality predictive models with strong scalability.
Objective To evaluate the effects of enhanced external counterpulsation (EECP) on exercise capacity and quality of life in patients with chronic heart failure. Methods PubMed, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM databases from January 1, 2010 to October 1, 2022 were searched by computer for the randomized controlled trial (RCT) about the intervention of EECP in patients with heart failure. Two researchers independently screened literature and extracted data. The meta-analysis was performed by RevMan 5.3. Results Nineteen RCTs were included. After EECP treatment, 6-minute walk distance (MD=57.37, 95%CI 40.89 to 70.85, P<0.001) and left ventricular ejection fraction improved (SMD=0.85, 95%CI 0.55 to 1.14, P<0.001). B-type natriuretic peptide decreased significantly (SMD=−0.67, 95%CI −1.09 to −0.25, P=0.002). The left ventricular end diastolic diameter (MD=−7.77, 95%CI −11.49 to −4.04, P<0.001), and the left ventricular end systolic diameter were significantly reduced (MD=−8.53, 95%CI −13.47 to −3.60, P<0.001). The quality of life of patients was improved (MD=16.34, 95%CI 0.59 to 32.10, P=0.04). Conclusion EECP can improve the exercise ability and the quality of life in patients with heart failure. However, more and larger well-designed RCTs are still needed to verify this conclusion.
Objective To compare the early outcomes of domestic third-generation magnetically levitated left ventricular assist device (LVAD) with or without concomitant mitral valvuloplasty (MVP). Methods The clinical data of 17 end-stage heart failure patients who underwent LVAD implantation combined with preoperative moderate to severe mitral regurgitation in Fuwai Central China Cardiovascular Hospital from May 2018 to March 2023 were retrospectively analyzed. The patients were divided into a LVAD group and a LVAD+MVP group based on whether MVP was performed simultaneously, and early outcomes were compared between the two groups. Results There were 4 patients in the LVAD group, all males, aged (43.5±5.9) years, and 13 patients in the LVAD+MVP group, including 10 males and 3 females, aged (46.8±16.7) years. All the patients were successful in concomitant MVP without mitral reguragitation occurrence. Compared with the LVAD group, the LVAD+MVP group had a lower pulmonary artery systolic pressure and pulmonary artery mean pressure 72 h after operation, but the difference was not statistically different (P>0.05). Pulmonary artery systolic pressure was significantly lower 1 week after operation, as well as pulmonary artery systolic blood pressure and pulmonary artery mean pressure at 1 month after operation (P<0.01). There was no statistically significant difference in blood loss, operation time, cardiopulmonary bypass time, aortic cross-clamping time, mechanical ventilation time, or ICU stay time between the two groups (P>0.05). The differences in 1-month postoperative mortality, acute kidney injury, reoperation, gastrointestinal bleeding, and thrombosis and other complications between the two groups were not statistically significant (P>0.05). Conclusion Concomitant MVP with implantation of domestic third-generation magnetically levitated LVAD is safe and feasible, and concomitant MVP may improve postoperative hemodynamics without significantly increasing perioperative mortality and complication rates.
