Clinical prevalence and outcome of cardiovascular events in the first 100 days postallogeneic hematopoietic stem cell transplant

Cardiovascular Considerations in Patients Undergoing Hematopoietic Cell Transplantation

OPINION STATEMENT

Cardiac dysfunction is a serious adverse effect of cancer therapies that can interfere with quality of life and impact long-term survival in patients with cancer. Hematopoietic cell transplantation is a potentially curative therapy for many advanced hematologic malignancies and bone marrow failure syndromes, however is associated with several short- and long-term adverse effects, including importantly, cardiovascular toxicities. The goal of this review article is to describe the cardiovascular events that may develop before, during, and after hematopoietic cell transplantation, review risk factors for short- and long-term cardiovascular toxicities, discuss approaches to cardiovascular risk stratification and evaluation, and highlight the research gaps in the consideration of cardiovascular disease in patients undergoing hematopoietic cell transplantation. Further understanding of cardiovascular events and the factors associated with cardiovascular disease will hopefully lead to novel interventions in managing and mitigating the significant long-term burden of late cardiovascular effects in transplant survivors.

Cardiovascular Disease After Hematopoietic Stem Cell Transplantation in Adults: JACC: CardioOncology State-of-the-Art Review

The use of hematopoietic cell transplantation (HCT) has expanded in the last 4 decades to include an older and more comorbid population. These patients face an increased risk of cardiovascular disease after HCT. The risk varies depending on several factors, including the type of transplant (autologous or allogeneic). Many therapies used in HCT have the potential to be cardiotoxic. Cardiovascular complications after HCT include atrial arrhythmias, heart failure, myocardial infarction, and pericardial effusions. Before HCT, patients should undergo a comprehensive cardiovascular assessment, with ongoing surveillance tailored to their individual level of cardiovascular risk. In this review, we provide an overview of cardiotoxicity after HCT and outline our approach to risk assessment and ongoing care.

Risk factors and survival outcomes in children with early cardiotoxicity after allogeneic hematopoietic stem cell transplantation

Cardiotoxicity in children is a potentially fatal complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT); therefore, early identification of risk factors can improve patient prognosis. However, there are few data on the clinical characteristics of early-stage cardiotoxicity in children after allo-HSCT. We conducted a retrospective single-center study of pediatric patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) between January 2016 and December 2022 at the Children's Hospital Affiliated with Chongqing Medical University to evaluate the clinical characteristics of early cardiac events (ECEs) after allo-HSCT and their impact on survival outcomes. We enrolled 444 patients who underwent allo-HSCT-304 males (68%) and 140 females (32%)-with a median age of 3.3 years (1.8-6.5 years) at transplantation. We found that 73 patients (16.4%) had ECEs after allo-HSCT. The ECEs included valvular disease (n = 46), pericardial effusion (n = 38), arrhythmia (n = 9), heart failure (n = 16), and dilated cardiomyopathy (n = 1). Female sex, age ≥ 6 years, body mass index (BMI) < 16 kg/m2 and HLA-type mismatches were risk factors for ECEs. We designed a stratified cardiac risk score that included these risk factors, and the higher the score was, the greater the cumulative incidence of ECEs. The occurrence of an ECE was closely associated with a lower overall survival (OS) rate and greater nonrelapse mortality (NRM). In addition, stratified analysis based on the number of combined ECEs showed that the greater the number of combined ECEs was, the more significant the negative impact on OS rates.

Cardiovascular Management of Patients Undergoing Hematopoietic Stem Cell Transplantation: From Pretransplantation to Survivorship: A Scientific Statement From the American Heart Association

Hematopoietic stem cell transplantation can cure various disorders but poses cardiovascular risks, especially for elderly patients and those with cardiovascular diseases. Cardiovascular evaluations are crucial in pretransplantation assessments, but guidelines are lacking. This American Heart Association scientific statement summarizes the data on transplantation-related complications and provides guidance for the cardiovascular management throughout transplantation. Hematopoietic stem cell transplantation consists of 4 phases: pretransplantation workup, conditioning therapy and infusion, immediate posttransplantation period, and long-term survivorship. Complications can occur during each phase, with long-term survivors facing increased risks for late effects such as cardiovascular disease, secondary malignancies, and endocrinopathies. In adults, arrhythmias such as atrial fibrillation and flutter are the most frequent acute cardiovascular complication. Acute heart failure has an incidence ranging from 0.4% to 2.2%. In pediatric patients, left ventricular systolic dysfunction and pericardial effusion are the most common cardiovascular complications. Factors influencing the incidence and risk of complications include pretransplantation therapies, transplantation type (autologous versus allogeneic), conditioning regimen, comorbid conditions, and patient age. The pretransplantation cardiovascular evaluation consists of 4 steps: (1) initial risk stratification, (2) exclusion of high-risk cardiovascular disease, (3) assessment of cardiac reserve, and (4) optimization of cardiovascular reserve. Clinical risk scores could be useful tools for the risk stratification of adult patients. Long-term cardiovascular management of hematopoietic stem cell transplantation survivors includes optimizing risk factors, monitoring, and maintaining a low threshold for evaluating cardiovascular causes of symptoms. Future research should prioritize refining risk stratification and creating evidence-based guidelines and strategies to optimize outcomes in this growing patient population.

Cardiovascular Events After Hematopoietic Stem Cell Transplant: Incidence and Risk Factors

Background

Hematopoietic stem cell transplantation (HSCT) is associated with various cardiovascular (CV) complications.

Objectives

We sought to characterize the incidence and risk factors for short-term and long-term CV events in a contemporary cohort of adult HSCT recipients.

Methods

We conducted a multicenter observational study of adult patients who underwent autologous or allogeneic HSCT between 2008 and 2019. Data on demographics, clinical characteristics, conditioning regimen, and CV outcomes were collected through chart review. CV outcomes were a composite of CV death, myocardial infarction, heart failure, atrial fibrillation/flutter, stroke, and sustained ventricular tachycardia and were classified as short-term (≤100 days post-HSCT) or long-term (>100 days post-HSCT).

Results

In 3,354 patients (mean age 55 years; 40.9% female; 30.1% Black) followed for a median time of 2.3 years (Q1-Q3: 1.0-5.4 years), the 100-day and 5-year cumulative incidences of CV events were 4.1% and 13.9%, respectively. Atrial fibrillation/flutter was the most common short- and long-term CV event, with a 100-day incidence of 2.6% and a 5-year incidence of 6.8% followed by heart failure (1.1% at 100 days and 5.4% at 5 years). Allogeneic recipients had a higher incidence of long-term CV events compared to autologous recipients (5-year incidence 16.4% vs 12.1%; P = 0.002). Baseline CV comorbidities were associated with a higher risk of long-term CV events.

Conclusions

The incidence of short-term CV events in HSCT recipients is relatively low. Long-term events were more common among allogeneic recipients and those with pre-existing CV comorbidities.

[Left ventricular dysfunction in patients following high-dose chemotherapy and autologous hematopoietic stem cell transplantation]

AIM

To evaluate the dynamics of LV global longitudinal strain (GLS) and other EchoCG parameters after high-dose chemotherapy (HDCT) and autologous hematopoietic stem cell transplantation (aHSCT).

MATERIAL AND METHODS

The risk of LV dysfunction in patients after HDCT followed by aHSCT has not been sufficiently studied. This study included 74 patients with hemoblastosis aged 20 to 65 years who had undergone HDCT followed by aHSCT. All patients had a history of antitumor treatment. EchoCG with assessment of LV GLS and measurements of troponin T and N-terminal pro-brain natriuretic peptide (NT-proBNP) were performed for all patients before and after the treatment.

RESULTS

A decrease in GLS by 15 % or more from the baseline was detected in 6 (8.1 %) patients. The decrease in GLS was associated with increased NT-proBNP >125 pg / ml at baseline (odds ratio, 8.667; 95 % confidence interval, 1.419-52.942; p=0.022).

CONCLUSION

The decrease in LV GLS in patients after aHSCT was associated with increased NT-proBNP before the intervention.

Atypical Presentation of Acute Pericarditis Secondary to Allogeneic Hematopoietic Stem Cell Transplantation: A Case Report

Cardiotoxicity linked with hematopoietic stem cell transplantation (HSCT) is a well-described phenomenon associated with an increased mortality risk; however, the majority of cardiac events present over 100 days following transfusion and are often attributed to graft-versus-host disease or pre-treatment conditioning by chemotherapy with or without radiation therapy. Here, we present the case of a 60-year-old female with a medical history of chronic lymphocytic leukemia complicated by a myelodysplastic syndrome that progressed to acute myeloid leukemia who developed chest pain immediately following an allogeneic HSCT. Electrocardiogram showed dynamic ST-depressions in leads V3-5 without evidence of reciprocal changes. Transthoracic echocardiography revealed pericardial effusion without signs of tamponade. The patient was thought to have acute pericarditis and was subsequently treated with high-dose intravenous methylprednisolone with a taper for two weeks. Her symptoms promptly subsided, and the pericardial effusion resolved on repeat echocardiography, which confirmed the diagnosis. Acute pericarditis is a rarely described complication of HSCT that is fatal if left untreated and prompts urgent management. This atypical case of acute pericarditis in the early post-transplant phase highlights the importance of cardiac stratification in patients with active malignancy undergoing treatment. It would suggest a potential benefit in closely monitoring high-risk individuals who have a history of coronary artery disease, smoking, or pericarditis in the pre-engraftment phase of transplantation.

Cardiovascular events among recipients of hematopoietic stem cell transplantation-A systematic review and meta-analysis

Cardiovascular diseases are an emerging cause of mortality and morbidity in survivors of hematopoietic stem cell transplantation (HSCT); however, the incidence of cardiovascular events (CVEs) in this population is not well described. This systematic review summarizes the evidence on the incidence of CVEs in HSCT recipients. Medline and Embase were searched from inception to December 2020. Inclusion criteria were cohort studies and phase 3 randomized controlled trials that reported CVEs among adults who underwent HSCT for hematological malignancies. After reviewing 8386 citations, 57 studies were included. The incidence of CVEs at 100 days was 0.19 (95% CI: 0.17-0.21) per 100 person-days after autologous HSCT and 0.06 (95% CI: 0.05-0.07) per 100 person-days after allogeneic HSCT. This higher incidence after autologous HSCT was driven by reports of arrhythmia from one population-based study in patients with multiple myeloma. The incidence of long-term CVEs was 3.98 (95% CI; 3.44-4.63) per 1000 person-years in survivors of autologous HSCT and 3.06 (95% CI; 2.69-3.48) per 1000 person-years in survivors of allogeneic HSCT. CVEs remain an important but under-reported cause of morbidity and mortality in recipients of HSCT. Future studies are required to better understand the incidence and risk factors for CVEs in HSCT recipients.

Cardiovascular diseases in patients after hematopoietic stem cell transplantation: Systematic review and Meta-analysis

BACKGROUND

Hematopoietic Stem Cell Transplantation (HSCT), is performed to treat many malignancies such as autologous or allogenic. Despite the success of this method in treating patients, - sometimes some HSCT recipients face problems such as cardiovascular complications. Therefore, this systematic review and meta-analysis aimed to evaluate the prevalence of cardiovascular complications in post-transplant patients.

METHOD

In order to review the published studies, we examined PubMed, MEDLINE, Cochrane Library, Scopus, and web of science databases from the beginning to the end of January 2022, and we used tools by the Newcastle-Ottawa Scale to evaluate the quality of the studies.

RESULT

In this study, 37 articles were included in the meta-analysis and 30,957 patients were examined. Also, the mean age of patients was 35.37 years. Based on the results of the meta-analysis, the prevalence of cardiovascular disease (CVD), was 16.84%. In addition, other complications related to CVD which include Arrhythmias, Congestive Heart Failure (CHF), Hypertension, stroke, and mortality were examined in patients who had hematopoietic stem cell transplantation and the resulting amounts were 3.91%, 3.66, 17.71, 0.22%, and 1.53%, respectively.

CONCLUSION

This study showed that the prevalence of cardiovascular disease after hematopoietic stem cell transplantation is high and needs special attention.

Cardiovascular Complications in Hematopoietic Stem Cell Transplanted Patients

Hematopoietic stem cell transplantation (HSCT) is the only curative treatment for many patients suffering from hematologic malignancies, solid tumors, inborn errors of metabolism or genetic disorders. Despite decades of successful HSCT, clinical outcomes are still far from satisfactory due to treatment-related complications, including graft-versus-host disease (GvHD) and cardiovascular complications (CVC). CVC may affect patients in the acute period post-HSCT; however, the occurrence is far higher among long-term survivors. Induction treatment using cardiotoxic treatments, e.g., anthracyclines and radiotherapy, conditioning regimens containing cyclophosphamide, and post-HSCT comorbidities, including GvHD, are factors contributing to CVC. Cardiac function evaluation prior to and post-transplantation is an important strategy for choosing the proper conditioning regimen, HSCT protocol and post-HSCT supportive care. Cardiac systolic function evaluation by echocardiography, in addition to serum cardiac biomarkers, such as troponins and brain natriuretic peptides, is recommended as a routine follow-up for HSCT patients. Angiotensin-converting enzyme inhibitors, angiotensin-II-receptor blockers, and beta-blockers, which are mostly used for the treatment of chemotherapy-induced cardiotoxicity, might be used as treatments for HSCT-related CVC. In summary, the present review reveals the urgent need for further investigations concerning HSCT-related CVC both at the preclinical and clinical levels due to the lack of knowledge about CVC and its underlying mechanisms.

Pharmaceutical Prevention and Management of Cardiotoxicity in Hematological Malignancies

Modern treatment modalities in hematology have improved clinical outcomes of patients with hematological malignancies. Nevertheless, many new or conventional anticancer drugs affect the cardiovascular system, resulting in various cardiac disorders, including left ventricular dysfunction, heart failure, arterial hypertension, myocardial ischemia, cardiac rhythm disturbances, and QTc prolongation on electrocardiograms. As these complications may jeopardize the significantly improved outcome of modern anticancer therapies, it is crucial to become familiar with all aspects of cardiotoxicity and provide appropriate care promptly to these patients. In addition, established and new drugs contribute to primary and secondary cardiovascular diseases prevention. This review focuses on the clinical manifestations, preventive strategies, and pharmaceutical management of cardiotoxicity in patients with hematologic malignancies undergoing anticancer drug therapy or hematopoietic stem cell transplantation.

Increased risk of cardio-cerebrovascular disease after hematopoietic cell transplantation in patients with previous history

Background:

The impacts of previous cardio-cerebrovascular disease (pre-CCVD) on the outcomes of hematopoietic cell transplantation (HCT) are not well described. Patients with pre-CCVD may often be poor candidates for HCT. This study aimed to investigate the impact of pre-CCVD on transplant outcomes.

Methods:

A retrospective study was conducted between patients with and without pre-CCVD who consecutively received allogeneic or autologous HCT between November 2013 and January 2020 with a matching of age and disease status. The cardiovascular complications and HCT outcomes of the two groups were evaluated and compared. The primary endpoints were post-transplant cardio-cerebrovascular disease (post-CCVD) and non-relapse mortality (NRM). We used a multivariable Cox proportional hazard model and the Fine-Gray competing risk regressions for analyses to estimate the hazard ratios (HRs).

Results:

The outcomes of 23 HCT recipients with pre-CCVD were compared with those of 107 patients in the control group. No significant differences were noted in terms of engraftment, overall survival (OS) (67.00% vs. 67.90%, P = 0.983), or relapse (29.78% vs. 28.26%, P = 0.561) between the pre-CCVD group and the control group. The cumulative incidences of 2-year NRM were similar between patients with pre-CCVD and the controls (14.68% vs. 17.08%, P = 0.670). However, pre-CCVD was associated with an increased incidence of post-CCVD (HR: 12.50, 95% confidence interval [CI]: 3.88–40.30, P < 0.001), which was an independent risk factor for increased NRM (HR: 10.29, 95% CI: 3.84–27.62, P < 0.001) and inferior OS (HR: 10.29, 95% CI: 3.84–27.62, P < 0.001).

Conclusions:

These findings suggest that the existence of pre-CCVD before transplantation might not result in increased mortality directly but superpose the toxicity of the transplantation procedure, leading to a risk of post-CCVD. Post-CCVD was a powerful predictor for high NRM and inferior OS. Further risk stratification of pre-CCVD is needed to reduce NRM in various transplantation settings.

Cardiovascular disease and its management in children and adults undergoing hematopoietic stem cell transplantation

Hematopoietic stem cell transplantation (HSCT) is a potentially curative treatment for many malignancies, hemoglobinopathies, metabolic diseases, bone marrow failure syndromes, and primary immune deficiencies. Despite the significant improvement in survival afforded by HSCT, the therapy is associated with major short and long-term morbidity and mortality. Cardiovascular complications such as cardiomyopathy, arrhythmias, pulmonary hypertension, and pericardial effusions are increasingly recognized as potential outcomes following HSCT. The incidence of cardiac complications is related to various factors such as age, co-morbid medical conditions, whether patients received cardiotoxic chemotherapy prior to HSCT, the type of HSCT (autologous versus allogeneic), and the specific conditioning regimen. Thus, the cardiovascular evaluation has become a core component of the pre-transplant assessment, however, the practice differs from center to center as national guidelines and contemporary high-quality studies are lacking. We review the incidence of cardiotoxicity in pediatric and adult HSCT, potential mechanisms of injury, and effects on long-term outcomes. We also discuss the possible therapeutic approaches when disease arises, as well as the indications and need for surveillance before, during, and after transplantation.

Cerebrovascular manifestations in hematological diseases: an update

Patients with hematological diseases often experience cerebrovascular complications including ischemic stroke, intracerebral and subarachnoid hemorrhage, microbleeds, posterior reversible encephalopathy syndrome, and dural sinus and cerebral vein thrombosis (CVT). In this update, we will review recent advances in the management of cerebrovascular diseases in the context of myeloproliferative neoplasms, leukemias, lymphomas, multiple myeloma, POEMS, paroxysmal nocturnal hemoglobinuria (PNH), thrombotic thrombocytopenic purpura (TTP), and sickle-cell disease. In acute ischemic stroke associated with hematological diseases, thrombectomy can in general be applied if there is a large vessel occlusion. Intravenous thrombolysis can be used in myeloproliferative neoplasms and sickle-cell anemia, but in other diseases, a case-by-case evaluation of the bleeding risks is mandatory. Patients with sickle-cell disease and acute stroke need very often to be transfused. In PNH, acute ischemic stroke patients must be anticoagulated. Most patients with CVT can be treated with low-molecular weight heparin (LMWH) acutely, even those with leukemias. Prevention of recurrence of cerebral thrombotic events depends on the control of the underlying disease, combined in some conditions with antithrombotic drugs. The recent introduction of specific monoclonal antibodies in the treatment of PHN and TTP has dramatically reduced the risk of arterial and venous thrombosis.

Mulberry leaf attenuates atherosclerotic lesions in patients with coronary heart disease possibly via 1-Deoxynojirimycin: A placebo-controlled, double-blind clinical trial

Mulberry leaf tea reduces atherosclerotic lesions and its main component is Deoxynojirimycin (DNJ). We aimed to explore the effects of Mulberry leaf DNJ (MLD) on atherosclerotic lesions in the patients with coronary heart disease (CHD). MLD and serum DNJ was detected by high-performance liquid chromatography (HPLC). The CHD patients with low-density lipoprotein cholesterol >140 mg/dl were assigned into the EG (MLD treatment) and the CG (placebo treatment) groups. Serum biochemical indices, the cerebrovascular and cardiovascular events and carotid intima-media thickness (IMT) were measured before and after a 1-year intervention. Pearson Correlation Coefficient test was used to explore the relationship between serum levels of DNJ and IMT values. Serum DNJ was 70 ± 50 ng/ml in the EG group but no serum DNJ was detected in the CG group. The incidence of cerebrovascular and cardiovascular events in the EG was lower than that in the CG group (p < .05). MLD therapy improved antioxidant and anti-inflammatory properties and serum lipid profile (p < .05). The IMT values in the EG group were lower than those in the CG group (p < .05). Serum levels of DNJ had a strong negative relationship with IMT values. MLD treatment attenuates atherosclerotic lesions possibly via DNJ. PRACTICAL APPLICATIONS: Mulberry leaves Deoxynojirimycin (MLD) treatment improved antioxidant and anti-inflammatory properties and serum lipid profile in heart disease patients. MLD reduce carotid intima-media thickness (IMT) and serum levels of DNJ (the main ingredient of mulberry leaf) had a strong relationship with IMT values. MLD is an amazing treat used for reducing the incidence of cerebrovascular and cardiovascular events in heart disease patients.
