BACKGROUND:Acute decompensated heart failure (HF) can progress to cardiogenic shock, and patients with cancer are at an increased risk of HF compared to patients without cancer. However, limited data exist on outcomes of patients admitted for HF-related cardiogenic shock (HF-CS) with cancer versus without cancer. METHODS:Adult patients admitted for HF-CS between 2014-2020 were identified using the National Readmission Database. Propensity score matching (PSM) was used to match 1 patient with cancer to 10 patients without cancer. Primary outcomes were in-hospital death, major bleeding, and thrombotic complications. Exploratory outcomes were 90-day readmission rates among patients who survived initial hospitalization. Temporal trends were also explored. RESULTS:Of 137,316 admissions for HF-CS, 7,306 (5.3%) had active cancer. After PSM, patients with cancer had increased odds of in-hospital death (OR 1.12, 95% CI 1.06 - 1.18), thrombotic complications (OR 1.12, 95% CI 1.03 - 1.21), and major bleeding (OR 1.23, 95% CI 1.17 - 1.31) compared to patients without cancer, with risks differing by cancer type. In exploratory analyses, rates of readmission were similar for patients with and without cancer. From 2014-2020, patients with cancer had no significant change in in-hospital mortality (ptrend = 0.43), while patients without cancer had decreased mortality over time (ptrend < 0.001). CONCLUSIONS:Among patients admitted for HF-CS, patients with cancer are at increased risk of in-hospital death, thrombotic complications, and major bleeding compared to patients without cancer. Future studies are needed to guide nuanced evaluation and management of this population to improve outcomes.

INTRODUCTION/BACKGROUND:Patients with congenital heart disease (CHD) are at increased risk of cancer. In patients with CHD and advanced heart failure, isolated heart transplantation (HT) can be considered. In the overall HT population, immunosuppression after HT increases the risk of post-transplant malignancy (PTM). However, cancer outcomes among adult HT patients with CHD have not been investigated. METHODS:Patients aged ≥ 18 years who received HT between January 1, 2010 and December 31, 2021 were identified using the United Network for Organ Sharing (UNOS) registry. Patients with CHD were compared to those without. T primary outcome was a composite outcome of PTM or death due to malignancy. Multivariable Fine-Gray competing-risk regression was used to estimate the subhazard ratio (SHR) of primary and secondary outcomes. RESULTS:Of the total of 29717 patients with HT were included, 1017 (3.4%) had CHD. Patients with CHD were younger, more likely to be female, and have had prior cardiac surgery. After multivariable competing-risk regression, CHD was associated with a higher risk of the primary outcome (SHR 1.43, 95% CI 1.15-1.80). Among patients who developed PTM, the median time to diagnosis of first PTM (median 36 vs. 46 months, p = 0.027) was shorter in patients with CHD. Among patients with CHD, survival after PTM was significantly lower compared with patients without malignancy (HR 3.32, 95% CI 2.03-5.43). CONCLUSIONS:Among adult patients with HT, CHD was associated with an increased risk of PTM. Further investigation is warranted to identify risk factors and screening strategies for malignancy in this patient population.

Heart failure (HF) in patients with cancer is associated with high morbidity and mortality. The success of cancer therapy has resulted in an exponential rise in the population of cancer survivors, however cardiovascular disease (CVD) is now a major life limiting condition more than 5 years after cancer diagnosis [Sturgeon, Deng, Bluethmann, et al 40(48):3889-3897, 2019]. Prevention and early detection of CVD, including cardiomyopathy (CM) and HF is of paramount importance. The European Society of Cardiology (ESC) published guidelines on Cardio-Oncology (CO) [Lyon, López-Fernández, Couch, et al 43(41):4229-4361, 2022] detailing cardiovascular (CV) risk stratification, prevention, monitoring, diagnosis, and treatment throughout the course and following completion of cancer therapy. Here we utilize a case to summarize aspects of the ESC guideline relevant to HF clinicians, with a focus on risk stratification, early detection, prevention of CM and HF, and the role for guideline directed medical therapy in patients with cancer.

Gastrointestinal cancers are a heterogenous group of cancers that share common risk factors with cardiovascular disease. Therapy for gastrointestinal cancers have improved cancer-specific outcomes at the cost of cardiotoxicity. The most common cardiotoxic therapies utilized in gastrointestinal cancers include conventional chemotherapy (including fluoropyrimidines and anthracyclines), targeted therapies including anti-vascular endothelial growth factor (VEGF) therapy and tyrosine kinase inhibitors (TKI), and immunotherapy. It is important for clinicians managing patients with gastrointestinal cancers to be aware of potential cardiotoxicity associated with these agents.

The prevalence of amyloidosis has been increasing, driven by a combination of improved awareness, evolution of diagnostic pathways, and effective treatment options for both transthyretin and light chain amyloidosis. Due to the complexity of amyloidosis, centralised expert providers with experience in delineating the nuances of confirmatory diagnosis and management may be beneficial. There are many potential benefits of a centre of excellence designation for the treatment of amyloidosis including recognition of institutions that have been leading the way for the optimal treatment of this condition, establishing the expectations for any centre who is engaging in the treatment of amyloidosis and developing cooperative groups to allow more effective research in this disease space. Standardising the expectations and criteria for these centres is essential for ensuring the highest quality of clinical care and community education. In order to define what components are necessary for an effective centre of excellence for the treatment of amyloidosis, we prepared a survey in cooperation with a multidisciplinary panel of amyloidosis experts representing an international consortium. The purpose of this position statement is to identify the essential elements necessary for highly effective clinical care and to develop a general standard with which practices or institutions could be recognised as a centre of excellence.

BACKGROUND/UNASSIGNED:Cardiogenic shock (CS) is the leading cause of death among patients with acute myocardial infarction (AMI) and is managed with temporary mechanical circulatory support (tMCS) in advanced cases. Patients with cancer are at high risk of AMI and CS. However, outcomes of patients with cancer and AMI-CS managed with tMCS have not been rigorously studied. METHODS/UNASSIGNED:Adult patients with AMI-CS managed with tMCS from 2006 to 2018 with and without cancer were identified using the National Inpatient Sample. Propensity score matching (PSM) was performed for variables associated with cancer. Primary outcome was in-hospital death, and secondary outcomes were major bleeding and thrombotic complications. RESULTS/UNASSIGNED:< .001). After PSM, there was no difference in in-hospital death (odds ratio [OR], 1.00; 95% CI, 0.88-1.13) or thrombotic complications (OR, 1.10; 95% CI, 0.91-1.34) between patients with and without cancer. Patients with cancer had a higher risk of major bleeding (OR, 1.29; 95% CI, 1.15-1.46). CONCLUSIONS/UNASSIGNED:Among patients with AMI-CS managed with tMCS, cancer is becoming increasingly frequent and associated with increased risk of major bleeding, although there was no difference in in-hospital death. Further studies are needed to further characterize outcomes, and inclusion of patients with cancer in trials of tMCS is needed.

BACKGROUND/UNASSIGNED:mutation, the most common driver mutation in MPNs, have shown accelerated adverse cardiac remodeling in myocardial infarction and pressure overload HF models. However, clinical outcomes, including in-hospital and readmission outcomes, of patients with MPN admitted for HF have not been well characterized. METHODS/UNASSIGNED:Patients hospitalized for HF with and without MPN were identified using the 2017 and 2018 National Readmission Database. Propensity score matching (PSM) was performed to match 1 MPN with 10 non-MPN controls. Outcomes were in-hospital death, 90-day CV-related, HF-related, and all-cause readmissions. Logistic regression and Cox proportional hazards regression models were used to estimate risk of in-hospital death and 90-day readmission outcomes, respectively. RESULTS/UNASSIGNED:After PSM, 4,626 patients with MPN were matched with 46,260 without. Patients with MPN were associated with increased risk of in-hospital death (OR 1.17, 95% CI 1.00 - 1.35), 90-day CV-related (HR 1.10, 95% CI 1.02 - 1.18) and all-cause (HR 1.24, 95% CI 1.17 - 1.31) but not HF-related (HR 1.05, 95% CI 0.97 - 1.14) readmissions. CONCLUSION/UNASSIGNED:Among patients hospitalized for HF, MPN was associated with increased risk of in-hospital death, and 90-day CV-related readmissions (driven primarily by thrombotic readmissions). Further investigation is needed in order to improve outcomes in patients with MPN and HF.
