Disseminated Intravascular Coagulation in Acute Promyelocytic Leukemia Patients: A Retrospective Analysis of Outcomes and Healthcare Burden in US Hospitals

Objective: Acute promyelocytic leukemia (APL) is associated with an elevated risk of developing disseminated intravascular coagulation (DIC). The purpose of this study was to assess the outcomes of hospitalizations related to DIC in APL and their impact on healthcare. Materials and Methods: This study entailed a cross-sectional and retrospective analysis of the US National Inpatient Sample database. We identified adults with APL and categorized them into groups of patients with and without DIC. Our focus areas included in-hospital mortality, length of stay, charges, and complications associated with DIC. Unadjusted odds ratios/coefficients were computed in univariate analysis, followed by adjusted odds ratios (aOR)/coefficients from multivariate analysis that accounted for confounding factors. Results: Our analysis revealed that APL patients with DIC had a substantially higher aOR for mortality (aOR: 6.68, 95% confidence interval [CI]: 4.76-9.37, p<0.001) and a prolonged length of stay (coefficient: 10.28 days, 95% CI: 8.48-12.09, p<0.001) accompanied by notably elevated total hospital charges (coefficient: $215,512 [95% CI: 177,368-253,656], p<0.001), thereby emphasizing the reality of extended medical care and economic burden. The presence of DIC was associated with increased odds of sepsis, vasopressor support, pneumonia, acute respiratory failure, intubation/mechanical ventilation, and acute kidney injury, reflecting heightened vulnerability to these complications. Patients with DIC demonstrated significantly higher odds ratios for major bleeding, intracranial hemorrhage, gastrointestinal bleeding, red blood cell transfusion, platelet transfusion, fresh frozen plasma transfusion, and cryoprecipitate transfusion, highlighting the pronounced hematological risks posed by DIC. Conclusion: This study has revealed the significant associations between DIC in APL and various outcomes, underscoring the clinical and economic implications of these conditions. The hematological risks further increase patients' vulnerability to bleeding events and the need for transfusions.

Anti-PF4 antibodies and their relationship with COVID infection.

Detecting anti-PF4 antibodies remains the golden diagnostic method for heparin-induced thrombocytopenia (HIT) diagnosis with high sensitivity and specificity. Various lab tests detect anti-PF4 antibodies, including immunoassays and functional assays. Even with positive detection of the anti-PF4 antibody, several factors are involved in the result. The concept of anti-PF4 disorders was recently brought to light during the COVID pandemic since the development of vaccine-induced thrombotic thrombocytopenia (VITT) with the adenovirus-vectored-DNA vaccine during the pandemic. Circumstances that detect anti-PF4 antibodies are classified as anti-PF4 disorders, including VITT, autoimmune HIT and spontaneous HIT. Some studies showed a higher percentage of anti-PF4 antibody detection among the population infected by COVID-19 without heparin exposure and some supported the theory that the anti-PF4 antibodies were related to the disease severity. In this review article, we provide a brief review of anti-PF4 disorders and summarize the current studies of anti-PF4 antibodies and COVID-19 infection.

Castleman disease- demographics, associations, and outcomes: an analysis of adult 791 cases.

BACKGROUND: Castleman disease (CD), also known as angiofollicular lymph node hyperplasia or large lymph node hyperplasia, is a rare medical condition. Despite its rarity, it exhibits diverse clinical presentations and outcomes, which pose challenges for comprehensive understanding and management. This study aims to shed light on the demographics, associations, and outcomes of CD by conducting a retrospective analysis. METHODS: The National Inpatient Sample (US) was used to identify patients with the diagnosis of Castleman disease using ICD-10 diagnosis code D47.Z2, during the years 2016-2019. Data was collected on demographics, associated diagnoses, treatments and outcomes. Data analysis was performed using STATA Version 17, College Station, TX: Stata Corp LLC. RESULTS: Our study identified 791 hospitalizations involving adult CD patients. The mean age of these patients was 52.4 years, with a male predominance (56.1%). Whites comprised the largest racial group affected (50.1%). Most patients were covered by Medicare (39.6%). The majority received treatment in urban teaching hospitals (84.0%) and large-bed size facilities (62.5%). In-hospital mortality was low at 2.8%, with an average length of stay of 7.5 days and average total charges of $109,308. Common associations included acute kidney injury (27.0%), congestive heart failure (17.1%), sepsis (16.4%), and acute respiratory failure (12.6%). Hematological and lymphatic associations featured anemia (47.5%), thrombocytopenia (12.2%), and other conditions. Red blood cell transfusions were administered to 11.1% of patients. CONCLUSION: This study contributes valuable insights into CD, a rare and clinically heterogeneous disease. It underscores the importance of recognizing its associations and complications. Additionally, it highlights the need for further research and improved diagnostic and treatment guidelines to address the complexity of this condition.

Cytokine Release Syndrome in Patients Treated With Chimeric Antigen Receptor T-cell Therapy: A Retrospective Study Analyzing Risks, Outcomes, and Healthcare Burden.

Background Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a promising immunotherapy for various malignancies. However, its use is associated with challenges, including cytokine release syndrome (CRS), a potentially severe complication. This retrospective study aims to analyze the risks, outcomes, and healthcare burden of CRS in patients undergoing CAR-T therapy. Method Data from the 2020 National Inpatient Sample (NIS) were utilized, comprising 415 CAR-T-related hospitalizations. They were categorized into those with CRS (n = 68) and those without CRS (n = 347). Baseline characteristics, including age, gender, race, income, insurance status, and comorbidities, were compared. Outcomes of interest included in-hospital mortality, length of stay (LOS), total hospital charges, and access to complications, associations, and interventions. Statistical analyses, including multivariable models, were employed to assess associations. Results Hospitalizations with CRS did not exhibit significant differences in age, gender, race, income, or insurance status compared to those without CRS. The multivariable analysis showed no statistically significant difference in mortality (adjusted odds ratio (aOR) = 2.48, 95% confidence interval (CI): 0.71 to 8.69, p = 0.151), LOS (coefficient = -2.1 days, 95% CI: -5.43 to 1.21, p = 0.207), or total hospital charges (coefficient = $207,456, 95% CI: $6119 to $421,031, p = 0.057) between the two groups. The CRS group had a higher incidence of fever (aOR = 1.91, 95% CI: 1.15 to 3.17, p = 0.014), acute respiratory failure (aOR = 2.10, 95% CI: 1.01 to 4.40, p= 0.049), and the need for intubation/mechanical ventilation (aOR = 2.59, 95% CI: 1.14 to 5.88, p = 0.024). Hemophagocytic lymphohistiocytosis (HLH) was significantly associated with CRS (aOR = 6.72, 95% CI: 2.03 to 22.18, p = 0.002). Conclusion While the development of CRS in CAR-T-treated patients did not significantly increase mortality, LOS, or total hospital charges, it was associated with specific risks and outcomes, including fever, respiratory failure, and HLH. This study emphasizes the importance of vigilance in recognizing and managing CRS in CAR-T therapy to optimize patient outcomes. The findings contribute valuable insights to guide clinical decision-making in the context of CAR-T therapy.

Metaxalone-induced Immune Hemolytic Anemia.

Drug-induced immune hemolytic anemia (DIIHA) is a relatively uncommon cause of anemia, and its diagnosis can be challenging. Although beta-lactam antimicrobial agents are often associated with DIIHA, any medication can potentially cause it. We describe a patient presenting with yellow skin discoloration and orange-colored urine after starting metaxalone for treatment of lumbosacral sprain. Laboratory studies were consistent with warm hemolytic anemia. Symptoms improved remarkably after discontinuation of metaxalone, coupled with initiation of glucocorticoids and rituximab.

Immunotherapy and Antiangiogenic Therapy for the Treatment of Patients With Advanced Renal Cell Carcinoma: A Systematic Review and an Updated Network Meta-Analysis of Phase III Clinical Trials.

In advanced renal cell carcinoma, few randomized controlled trials involving immunotherapy plus antiangiogenic therapy have shown survival benefits relative to Sunitinib. Our meta-analysis aimed to evaluate the efficacy and safety of combined immunotherapy and antiangiogenic therapy compared to Sunitinib therapy alone in patients with advanced renal cell carcinoma. Six phase III randomized controlled trials were analyzed, including 4,119 patients. The primary endpoints were overall survival and progression-free survival, and the secondary endpoints were objective response rate and serious adverse events. The results showed that combined immunotherapy and antiangiogenic therapy significantly improved overall survival, progression-free survival, and objective response rate compared to Sunitinib alone. No significant difference was observed in adverse events between the two groups. This study suggests that combined immunotherapy and antiangiogenic therapy is a great treatment option for advanced renal cell carcinoma.

Efficacy and safety of catheter ablation for atrial fibrillation in patients with history of cancer.

BACKGROUND: Though the incidence of atrial fibrillation (AF) is increased in patients with cancer, the effectiveness of catheter ablation (CA) for AF in patients with cancer is not well studied. METHODS: We conducted a retrospective cohort study of patients who underwent CA for AF. Patients with a history of cancer within 5-years prior to, or those with an exposure to anthracyclines and/or thoracic radiation at any time prior to the index ablation were compared to patients without a history of cancer who underwent AF ablation. The primary outcome was freedom from AF [with or without anti-arrhythmic drugs (AADs), or need for repeat CA at 12-months post-ablation]. Secondary endpoints included freedom from AF at 12 months post-ablation with AADs and without AADs. Safety endpoints included bleeding, pulmonary vein stenosis, stroke, and cardiac tamponade. Multivariable regression analysis was performed to identify independent risk predictors of the primary outcome. RESULTS: Among 502 patients included in the study, 251 (50%) had a history of cancer. Freedom from AF at 12 months did not differ between patients with and without cancer (83.3% vs 72.5%, p 0.28). The need for repeat ablation was also similar between groups (20.7% vs 27.5%, p 0.29). Multivariable regression analysis did not identify a history of cancer or cancer-related therapy as independent predictors of recurrent AF after ablation. There was no difference in safety endpoints between groups. CONCLUSION: CA is a safe and effective treatment for AF in patients with a history of cancer and those with exposure to potentially cardiotoxic therapy.

Efficacy and safety of Nivolumab in patients with advanced esophageal, gastroesophageal, and gastric cancers: a meta-analysis of randomized controlled trials.

BACKGROUND: Immune checkpoint inhibitors (ICI) have revolutionized care in oncology with improved overall survival in several cancer populations. Nivolumab has recently been approved for use in patients with upper gastrointestinal cancers. We quantitatively summarized the efficacy and safety of Nivolumab use in patients with advanced esophageal, gastroesophageal, and gastric carcinoma compared to standard chemotherapy. METHODS: Systemic search of electronic databases was performed to analyze phase III randomized controlled trials (RCTs) comparing Nivolumab versus standard chemotherapy in patients with advanced upper gastrointestinal cancers. Primary endpoints were overall survival (OS) and progression-free survival (PFS). Data were pooled using random effects model via RevMan 5.4 software. RESULTS: Four RCTs with a total of 3369 patients and a median follow-up of 13 months were included. The patients' mean age was 61 ± 20 years, 74.6% were males, and 26% had ≥1% PD-L1 expression. Compared to the chemotherapy group, Nivolumab group had a significantly favorable OS and PFS [HR 0.81;95% CI (0.74, 0.89), p < .001], [HR 0.82;95% CI (0.69, 0.98), p = .03], respectively. Nivolumab significant effect was only in patients with ≥1% PD L1 expression [HR 0.72; 95% CI (0.58, 0.89), p < .001]. No statistical difference was detected between groups regarding serious adverse effects (AE) [OR 1.47; 95%CI (0.94,2.31), p = 0.09]. CONCLUSIONS: Compared to standard chemotherapy, the use of Nivolumab in patients with advanced esophageal, gastroesophageal, and gastric cancers is associated with improved overall and progression-free survival, with similar rates of AE and AE leading to death. The improvement in survival was significant in patients with ≥1% PD L1 expression.

Cardiac Sarcoma Presenting as Tamponade.

Sarcomas are a broad group of neoplasm that originate from the mesenchymal layer and represent about 1% of malignancy in the adult population. We describe a 46-year-old woman with no prior medical history who presented with worsening dyspnea. Physical examination was significant for jugular venous distension and bilateral lower extremity edema. Chest Xray showed cardiomegaly. Echocardiography showed a normal ejection fraction of 65%, pericardial effusion with tamponade physiology and three epicardial masses. Patient had pericardiocentesis performed followed by pericardial window. Biopsy of pericardial mass showed morphologic and immunophenotypic findings supportive of diagnosis of malignant soft tissue sarcoma. Though this type of cancer is rare, malignancy should be included as one of the differential diagnoses of new-onset pericardial effusion in a young patient. Early diagnosis and referral to a specialized sarcoma center for treatment is recommended.

Strategies for Cardio-Oncology Care During the COVID-19 Pandemic.

Purpose of review: The COVID-19 pandemic has disrupted healthcare and has disproportionately affected the marginalized populations. Patients with cancer and cardiovascular disease (cardio-oncology population) are uniquely affected. In this review, we explore the current data on COVID-19 vulnerability and outcomes in these patients and discuss strategies for cardio-oncology care with a focus on healthcare innovation, health equity, and inclusion. Recent findings: The growing evidence suggest increased morbidity and mortality from COVID-19 in patients with comorbid cancer and cardiovascular disease. Additionally, de novo cardiovascular complications such as myocarditis, myocardial infarction, arrhythmia, heart failure, and thromboembolic events have increasingly emerged, possibly due to an accentuated host immune response and cytokine release syndrome. Summary: Patient-centric policies are helpful for cardio-oncology surveillance like remote monitoring, increased use of biomarker-based surveillance, imaging modalities like CT scan, and point-of-care ultrasound to minimize the exposure for high-risk patients. Abundant prior experience in cancer therapy scaffolded the repurposed use of corticosteroids, IL-6 inhibitors, and Janus kinase inhibitors in the treatment of COVID-19 infection. COVID-19 vaccine timing and dose frequency present a challenge due to overlapping toxicities and immune cell depletion in patients receiving cancer therapies. The SARS-CoV-2 pandemic laid bare social and ethnic disparities in healthcare but also steered in innovation to combat problems of patient outreach, particularly with virtual care. In the recovery phase, the backlog in cardio-oncology care, interplay of cancer therapy-related side effects, and long COVID-19 syndrome are crucial issues to address.

Paget-Schroetter Syndrome (PSS) and Adjunctive Treatment With Mechanical Aspiration Thrombectomy and Catheter Directed Thrombolysis: A Case Report and Review of Literature.

Paget-Schroetter syndrome, also known as venous thoracic outlet syndrome, is primarily an effort-induced thrombosis of the subclavian and axillary veins. Treatment modalities involve systemic anticoagulation, catheter-directed thrombolysis (CDT), and surgical decompression. Early endovascular intervention is noted to improve outcomes and result in symptomatic relief. Here we implore the usage of the novel mechanical aspiration thrombectomy device as an adjunct to CDT for the management of peripheral venous thrombosis and highlight it as a treatment option resulting in substantial radiological and symptomatic improvement.

Cyclic Thrombocytopenia: A Rare Cause of Recurrent Thrombocytopenia.

Cyclic thrombocytopenia (CTP) is a very rare hematological disorder that is characterized by periodic fluctuations in platelet counts. Diagnosis is generally delayed due to its similarity with immune thrombocytopenia (ITP). The pathophysiology is unknown and there are currently no guidelines for management. Many patients are usually treated for ITP initially prior to diagnosis. We describe a 67-year-old female with a history of multiple episodes of transient thrombocytopenia who presented to the hospital with another episode of thrombocytopenia. Her workup including HIV, hepatitis screening, vitamin B12, and folate was negative. She received a unit of platelet transfusion and was later observed in the hospital. Further review of her chart showed similar episodes in the past with spontaneous improvement. She was diagnosed with CTP. Her platelet count improved remarkably prior to discharge. In patients with recurrent fluctuation in their platelet count, CTP should be one of the differentials as this might prevent further unnecessary therapies.

POEMS Syndrome - A Diagnostic Dilemma with Challenging Presentation.

Polyneuropathy, Organomegaly, Endocrinopathy, M-protein, Skin changes (POEMS) syndrome is a rare disorder with multiple presentations and a constellation of symptoms. We present a 62 year-old female who presented to the Emergency Department for acute dyspnea. Chest Xray showed sclerotic lesions in the ribs and thoracic spine. Further imaging studies with computed tomography (CT) and positron emission tomography (PET) scans were suggestive of a benign process. Improvement was seen with supportive management. A few months later, patient developed neurological symptoms with reduced exercise tolerance. Mixed demyelinating and axonal polyneuropathy was diagnosed by electromyography. Further work up with bone marrow biopsy and immunochemistry testing revealed lambda and kappa plasma cell disorder, with elevated vascular endothelial growth factor (VEGF). Patient was diagnosed with POEMS and initiated on chemotherapy. POEMS syndrome is commonly missed due to its rarity and varied clinical presentations. VEGF plays a crucial role in the diagnosis. Management requires a multidisciplinary approach.

Assessment of self-reported adherence to ART and patient's virological/CD4 response in a tertiary care clinic and government free ART clinic.

INTRODUCTION: Treatment adherence to antiretroviral treatment (ART) is critical in reducing morbidity, mortality, and improving the survival in HIV patients. ART is a life-long commitment, and the variety of factors can influence treatment adherence. We studied the factors affecting treatment adherence in the private sector and public sector outdoor clinic in Ahmedabad, India. The primary objective of this study is to compare the level of adherence and factors that influence adherence to ART in patients attending government run free ART program and private setup. METHODS: We conducted a cross-sectional study of 8 weeks among HIV-infected patients who were receiving ART from private clinic and free ART center from July 2019 to September 2019. We enrolled all consecutive patients >18 years of age attending both clinics. Statistical analysis was carried out using the SPSS software version 25.0. Multiple logistic regression was used to identify the factors that were independently associated with adherence to ART. RESULTS: The study enrolled 306 patients, 151 (49.34%) from the outpatient department of private hospital, and 155 (50.65%) from the free ART center. Patients attending private clinics were more likely to have been diagnosed with HIV since ≥10 years compared to free ART center. Higher opportunistic infection rates were found in free ART center (64.51%). Treatment adherence was significantly lower in the patients attending free ART center (P = 0.004). Patients taking concomitant medications for other comorbid conditions (≥4 pills/day) were more likely to exhibit inadequate adherence ([odds ratio] 1.216, 95% confidence interval 1.0171-1.454). Univariate analysis showed that age, education, habits of alcohol, tobacco, number of pills, and duration of disease played a significant role in predicting adherence to ART (P < 0.05). CONCLUSIONS: Patients attending private clinic are surviving longer with HIV diagnosis, have fewer opportunistic infections, and have better treatment adherence compared to free ART clinic.

Cardiotoxicity of Immune Checkpoint Inhibitors.

PURPOSE OF REVIEW: Immune checkpoint inhibitors (ICIs) have improved the survival of several cancers. However, they may cause a wide range of immune-related adverse events (irAEs). While most irAEs are manageable with temporary cessation of ICI and immunosuppression, cardiovascular toxicity can be associated with high rates of morbidity and mortality. As ICIs evolve to include high-risk patients with preexisting cardiovascular risk factors and disease, the risk and relevance of ICI-associated cardiotoxicity may be even higher. RECENT FINDINGS: Several cardiovascular toxicities such as myocarditis, stress cardiomyopathy, and pericardial disease have been reported in association with ICIs. Recent findings also suggest an increased risk of atherosclerosis with ICI use. ICI-associated myocarditis usually occurs early after initiation and can be fulminant. A high index of suspicion is required for timely diagnosis. Prompt treatment with high-dose corticosteroids is shown to improve outcomes. Although the overall incidence is rare, ICI cardiotoxicity, particularly myocarditis, is associated with significant morbidity and mortality, making it a major therapy-limiting adverse event. Early recognition and prompt treatment with the cessation of ICI therapy and initiation of high-dose corticosteroids are crucial to improve outcomes. Cardio-oncologists will need to play an important role not just in the management of acute cardiotoxicity but also to reduce the risk of long-term sequelae.

Management of Patients With Giant Cell Myocarditis: JACC Review Topic of the Week.

Giant cell myocarditis is a rare, often rapidly progressive and potentially fatal, disease due to T-cell lymphocyte-mediated inflammation of the myocardium that typically affects young and middle-aged adults. Frequently, the disease course is marked by acute heart failure, cardiogenic shock, intractable ventricular arrhythmias, and/or heart block. Diagnosis is often difficult due to its varied clinical presentation and overlap with other cardiovascular conditions. Although cardiac biomarkers and multimodality imaging are often used as initial diagnostic tests, endomyocardial biopsy is required for definitive diagnosis. Combination immunosuppressive therapy, along with guideline-directed medical therapy, has led to a paradigm shift in the management of giant cell myocarditis resulting in an improvement in overall and transplant-free survival. Early diagnosis and prompt management can decrease the risk of transplantation or death, which remain common in patients who present with cardiogenic shock.

Niacinamide May Be Associated with Improved Outcomes in COVID-19-Related Acute Kidney Injury: An Observational Study.

Background: AKI is a significant complication of coronavirus disease 2019 (COVID-19), with no effective therapy. Niacinamide, a vitamin B3 analogue, has some evidence of efficacy in non-COVID-19-related AKI. The objective of this study is to evaluate the association between niacinamide therapy and outcomes in patients with COVID-19-related AKI. Methods: We implemented a quasi-experimental design with nonrandom, prospective allocation of niacinamide in 201 hospitalized adult patients, excluding those with baseline eGFR <15 ml/min per 1.73 m2 on or off dialysis, with COVID-19-related AKI by Kidney Disease Improving Global Outcomes (KDIGO) criteria, in two hospitals with identical COVID-19 care algorithms, one of which additionally implemented treatment with niacinamide for COVID-19-related AKI. Patients on the niacinamide protocol (B3 patients) were compared against patients at the same institution before protocol commencement and contemporaneous patients at the non-niacinamide hospital (collectively, non-B3 patients). The primary outcome was a composite of death or RRT. Results: A total of 38 out of 90 B3 patients and 62 out of 111 non-B3 patients died or received RRT. Using multivariable Cox proportional hazard modeling, niacinamide was associated with a lower risk of RRT or death (HR, 0.64; 95% CI, 0.40 to 1.00; P=0.05), an association driven by patients with KDIGO stage-2/3 AKI (HR, 0.29; 95% CI, 0.13 to 0.65; P=0.03; P interaction with KDIGO stage=0.03). Total mortality also followed this pattern (HR, 0.17; 95% CI, 0.05 to 0.52; in patients with KDIGO stage-2/3 AKI, P=0.002). Serum creatinine after AKI increased by 0.20 (SEM, 0.08) mg/dl per day among non-B3 patients with KDIGO stage-2/3 AKI, but was stable among comparable B3 patients (+0.01 [SEM, 0.06] mg/dl per day; P interaction=0.03). Conclusions: Niacinamide was associated with lower risk of RRT/death and improved creatinine trajectory among patients with severe COVID-19-related AKI. Larger randomized studies are necessary to establish a causal relationship.

Cardiotoxicity of Contemporary Anticancer Immunotherapy.

PURPOSE OF REVIEW: Contemporary anticancer immunotherapy, particularly immune checkpoint inhibitors (ICI) and chimeric antigen receptor (CAR) T cell therapy, has changed the landscape of treatment for patients with a variety of malignancies who historically had a poor prognosis. However, both immune checkpoint inhibitors and CAR T cell therapy are associated with serious cardiovascular adverse effects. As immunotherapy evolves to include high-risk patients with preexisting cardiovascular risk factors and disease, the risk and relevance of its associated cardiotoxicity will be even higher. RECENT FINDINGS: ICI can cause myocarditis, which usually occurs early after initiation, can be fulminant, and prompt treatment with high-dose corticosteroids is crucial. CAR T cell therapy frequently leads to cytokine release syndrome, which is associated with cardiomyopathy or arrhythmia development and may also result in circulatory collapse. Supportive treatment, as well as tocilizumab, an anti-interleukin-6 receptor antibody, is the cornerstone of treatment. Recent findings suggest that preexisting cardiovascular risk factors and disease may increase the risk of such cardiotoxicity, and prompt recognition, as well as treatment, may favorably alter the outcomes. SUMMARY: ICI and CAR T cell therapy have improved cancer-related outcomes; however, they both are associated with potentially therapy-limiting cardiotoxicity. Cardio-oncologists are required to play an important role in patient selection, pretherapy cardiovascular optimization, and prompt recognition and treatment of cardiotoxicity.

Outcomes of COVID-19 in Patients With a History of Cancer and Comorbid Cardiovascular Disease.

BACKGROUND: Cancer and cardiovascular disease (CVD) are independently associated with adverse outcomes in patients with COVID-19. However, outcomes in patients with COVID-19 with both cancer and comorbid CVD are unknown. METHODS: This retrospective study included 2,476 patients who tested positive for SARS-CoV-2 at 4 Massachusetts hospitals between March 11 and May 21, 2020. Patients were stratified by a history of either cancer (n=195) or CVD (n=414) and subsequently by the presence of both cancer and CVD (n=82). We compared outcomes between patients with and without cancer and patients with both cancer and CVD compared with patients with either condition alone. The primary endpoint was COVID-19-associated severe disease, defined as a composite of the need for mechanical ventilation, shock, or death. Secondary endpoints included death, shock, need for mechanical ventilation, need for supplemental oxygen, arrhythmia, venous thromboembolism, encephalopathy, abnormal troponin level, and length of stay. RESULTS: Multivariable analysis identified cancer as an independent predictor of COVID-19-associated severe disease among all infected patients. Patients with cancer were more likely to develop COVID-19-associated severe disease than were those without cancer (hazard ratio [HR], 2.02; 95% CI, 1.53-2.68; P<.001). Furthermore, patients with both cancer and CVD had a higher likelihood of COVID-19-associated severe disease compared with those with either cancer (HR, 1.86; 95% CI, 1.11-3.10; P=.02) or CVD (HR, 1.79; 95% CI, 1.21-2.66; P=.004) alone. Patients died more frequently if they had both cancer and CVD compared with either cancer (35% vs 17%; P=.004) or CVD (35% vs 21%; P=.009) alone. Arrhythmias and encephalopathy were also more frequent in patients with both cancer and CVD compared with those with cancer alone. CONCLUSIONS: Patients with a history of both cancer and CVD are at significantly higher risk of experiencing COVID-19-associated adverse outcomes. Aggressive public health measures are needed to mitigate the risks of COVID-19 infection in this vulnerable patient population.

Management of Cardiovascular Disease During Coronavirus Disease (COVID-19) Pandemic.

Patients with pre-existing cardiovascular disease and risk factors are more likely to experience adverse outcomes associated with the novel coronavirus disease-2019 (COVID-19). Additionally, consistent reports of cardiac injury and de novo cardiac complications, including possible myocarditis, arrhythmia, and heart failure in patients without prior cardiovascular disease or significant risk factors, are emerging, possibly due to an accentuated host immune response and cytokine release syndrome. As the spread of the virus increases exponentially, many patients will require medical care either for COVID-19 related or traditional cardiovascular issues. While the COVID-19 pandemic is dominating the attention of the healthcare system, there is an unmet need for a standardized approach to deal with COVID-19 associated and other traditional cardiovascular issues during this period. We provide consensus guidance for the management of various cardiovascular conditions during the ongoing COVID-19 pandemic with the goal of providing the best care to all patients and minimizing the risk of exposure to frontline healthcare workers.
