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.

Identifying patients for safe early hospital discharge following st elevation myocardial infarction.

OBJECTIVES: To examine whether the CADILLAC risk score is an effective method of patient stratification for early discharge following ST elevation myocardial infarction (STEMI). BACKGROUND: Patients with STEMI are typically hospitalized to monitor for serious complications such as arrhythmias, heart failure, and reinfarction. Optimal length of stay is unclear. Whether low risk patients can be safely discharged before 72 hr of hospitalization is unclear. METHODS: Patients with STEMI who underwent successful PCI were retrospectively stratified using CADILLAC risk score to low risk (n = 123) and intermediate to high risk (n = 105). The primary outcome was adverse clinical events at day 3 or later. Secondary outcomes were adverse clinical events on day 1 and mortality rates at 30 days and 31 to 365 days. RESULTS: Low risk patients had lower major adverse clinical events at day 3 or later (0 vs. 11.4%, P = 0.0002) and lower total mortality at 1 year (0 vs. 4.8%, P = 0.02) than patients with intermediate to high risk. Low risk patients were also less likely to have a cardiovascular event during the first 24 hr when compared to those with an intermediate to high risk score (3.3% vs. 13.3%, P = 0.006). CONCLUSION: Low risk patients identified using CADILLAC risk score with STEMI treated successfully with primary PCI have a low adverse event rate on the third day or later of hospitalization suggesting that an earlier discharge is safe in properly selected patients. Monitoring in a noncritical care setting following primary PCI for STEMI may be feasible for selected patients. © 2016 Wiley Periodicals, Inc.

Health-related quality of life in a multicenter randomized controlled comparison of telephonic disease management and automated home monitoring in patients recently hospitalized with heart failure: SPAN-CHF II trial.

BACKGROUND: Although disease management programs have been shown to provide a number of clinical benefits to patients with heart failure (HF), the incremental impact of an automated home monitoring (AHM) system on health-related quality of life (HRQL) is unknown. METHODS AND RESULTS: We performed a prospective randomized investigation, examining the additive value of AHM to a previously described nurse-directed HF disease management program (SPAN-CHF), with attention to HRQL, in patients with a recent history of decompensated HF. A total of 188 patients were randomized to receive the SPAN-CHF intervention for 90 days, either with (AHM group) or without (NAHM, standard-care group) AHM, with a 1:1 randomization ratio after HF-related hospitalization. HRQL, measured by the Minnesota Living With Heart Failure Questionnaire (MLHFQ) (Physical, Emotional, and Total scores on MLHFQ) was assessed at 3 time points: baseline, 45 days, and 90 days. Although both treatments (AHM and NAHM) improved HRQL at 45 and 90 days compared with baseline with respect to Physical, Emotional, and Total domain scales, no significant difference emerged between AHM and NAHM groups. CONCLUSIONS: AHM and NAHM treatments demonstrated improved HRQL scores at 45 and 90 days after baseline assessment. When comparing 2 state-of the-art disease management programs regarding HRQL outcomes, our results did not support the added value of AHM.

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.

A multicenter randomized controlled evaluation of automated home monitoring and telephonic disease management in patients recently hospitalized for congestive heart failure: the SPAN-CHF II trial.

BACKGROUND: We performed a prospective, randomized investigation assessing the incremental effect of automated health monitoring (AHM) technology over and above that of a previously described nurse directed heart failure (HF) disease management program. The AHM system measured and transmitted body weight, blood pressure, and heart rate data as well as subjective patient self-assessments via a standard telephone line to a central server. METHODS AND RESULTS: A total of 188 consented and eligible patients were randomized between intervention and control groups in 1:1 ratio. Subjects randomized to the control arm received the Specialized Primary and Networked Care in Heart Failure (SPAN-CHF) heart failure disease management program. Subjects randomized to the intervention arm received the SPAN-CHF disease management program in conjunction with the AHM system. The primary end point was prespecified as the relative event rate of HF hospitalization between intervention and control groups at 90 days. The relative event rate of HF hospitalization for the intervention group compared with controls was 0.50 (95%CI [0.25-0.99], P = .05). CONCLUSIONS: Short-term reductions in the heart failure hospitalization rate were associated with the use of automated home monitoring equipment. Long-term benefits in this model remain to be studied.

Risk and predictors of dyssynchrony cardiomyopathy in left bundle branch block with preserved left ventricular ejection fraction.

BACKGROUND: Left bundle branch block (LBBB) and left ventricular (LV) dyssynchrony likely contribute to progressive systolic dysfunction. The evaluation of newly recognized LBBB includes screening for structural heart abnormalities and coronary artery disease (CAD). In patients whose LV ejection fraction (EF) is preserved during initial testing, the incidence of subsequent cardiomyopathy is not firmly established. HYPOTHESIS: The risk of developing LV systolic dysfunction among LBBB patients with preserved LVEF is high enough to warrant serial imaging. METHODS: We screened records of 1000 consecutive patients with LBBB from our ECG database and identified subjects with an initially preserved LVEF (≥45%) without clinically relevant CAD or other cause for cardiomyopathy. Baseline imaging, clinical data, and follow-up imaging were recorded to determine the risk of subsequent LV systolic dysfunction (LVEF ≤40%). RESULTS: (Data are mean + SD) 784 subjects were excluded, the majority for CAD or depressed LVEF upon initial imaging. Of the remaining 216, 37 (17%) developed a decline in LVEF(≤40%) over a mean follow-up of 55 ± 31 months; 94% of these patients had a baseline LVEF≤60% and LV end systolic diameter (ESD) ≥ 2.9 cm indicating that these measures may be useful to define which patients warrant longitudinal follow-up. The negative predictive value of a LVEF>60% and LVESD <2.9 cm was 98%. CONCLUSIONS: Seventeen percent of patients with LBBB and initial preserved LVEF develop dyssynchrony cardiomyopathy. We believe the risk of developing dyssynchrony cardiomyopathy is high enough to warrant serial assessment of LV systolic function in this high-risk population.

Outcomes of Impella CP insertion during cardiac arrest: A single center experience.

OBJECTIVES: We sought to determine the outcomes of patients with an Impella CP percutaneous mechanical circulatory support (MCS) device deployed during a cardiac arrest. BACKGROUND: The Impella CP device is indicated for left ventricular support in patients with cardiogenic shock. The utility of percutaneous MCS in the setting of cardiac arrest during cardiopulmonary resuscitation (CPR) remains unclear. METHODS: We retrospectively examined data from patients supported with an Impella CP device for cardiogenic shock complicated by cardiac arrest between April 2015 and April 2017 at a single academic medical center. Patients with cardiac arrest who underwent Impella CP placement during CPR were compared to those who had return of spontaneous circulation (ROSC) prior to Impella CP placement. RESULTS: We identified 22 patients with cardiogenic shock complicated by cardiac arrest (average age 64 years, 23% female) who underwent placement of an Impella CP device. The majority of patients (68%) underwent support for cardiogenic shock secondary to an acute myocardial infarction. Seven of the 22 patients (32%) underwent Impella CP placement during CPR and 15 (68%) underwent Impella CP insertion following ROSC. The in-hospital mortality was 86% in the group of patients who had the Impella CP placed during CPR and 56% in the group with ROSC prior to Impella CP insertion, (p = 0.19). CONCLUSIONS: Based on our single center retrospective analysis, the mortality rate of patients undergoing placement of an Impella CP during CPR is 86%. Further study is necessary to better understand the utility of the Impella CP mechanical circulatory support device during a cardiac arrest.

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.

Upfront dexrazoxane for the reduction of anthracycline-induced cardiotoxicity in adults with preexisting cardiomyopathy and cancer: a consecutive case series.

BACKGROUND: Cardiotoxicity associated with anthracycline-based chemotherapies has limited their use in patients with preexisting cardiomyopathy or heart failure. Dexrazoxane protects against the cardiotoxic effects of anthracyclines, but in the USA and some European countries, its use had been restricted to adults with advanced breast cancer receiving a cumulative doxorubicin (an anthracycline) dose > 300 mg/m2. We evaluated the off-label use of dexrazoxane as a cardioprotectant in adult patients with preexisting cardiomyopathy, undergoing anthracycline chemotherapy. METHODS: Between July 2015 and June 2017, five consecutive patients, with preexisting, asymptomatic, systolic left ventricular (LV) dysfunction who required anthracycline-based chemotherapy, were concomitantly treated with off-label dexrazoxane, administered 30 min before each anthracycline dose, regardless of cancer type or stage. Demographic, cardiovascular, and cancer-related outcomes were compared to those of three consecutive patients with asymptomatic cardiomyopathy treated earlier at the same hospital without dexrazoxane. RESULTS: Mean age of the five dexrazoxane-treated patients and three patients treated without dexrazoxane was 70.6 and 72.6 years, respectively. All five dexrazoxane-treated patients successfully completed their planned chemotherapy (doxorubicin, 280 to 300 mg/m2). With dexrazoxane therapy, changes in LV systolic function were minimal with mean left ventricular ejection fraction (LVEF) decreasing from 39% at baseline to 34% after chemotherapy. None of the dexrazoxane-treated patients experienced symptomatic heart failure or elevated biomarkers (cardiac troponin I or brain natriuretic peptide). Of the three patients treated without dexrazoxane, two received doxorubicin (mean dose, 210 mg/m2), and one received daunorubicin (540 mg/m2). Anthracycline therapy resulted in a marked reduction in LVEF from 42.5% at baseline to 18%. All three developed symptomatic heart failure requiring hospitalization and intravenous diuretic therapy. Two of them died from cardiogenic shock and multi-organ failure. CONCLUSION: The concomitant administration of dexrazoxane in patients with preexisting cardiomyopathy permitted successful delivery of anthracycline-based chemotherapy without cardiac decompensation. Larger prospective trials are warranted to examine the use of dexrazoxane as a cardioprotectant in patients with preexisting cardiomyopathy who require anthracyclines.

Ibrutinib-Associated Atrial Fibrillation.

Ibrutinib, a novel and potent Bruton tyrosine kinase inhibitor, is an effective and well-tolerated treatment for a variety of B-cell lymphomas. However, its use is associated with an increased incidence of atrial fibrillation (AF), ranging from 4% to 16%. We reviewed the original clinical trials that led to the approval of ibrutinib, as well as several other prospective and retrospective studies, to better appreciate the incidence of ibrutinib-associated AF. Based on 16 studies included in our analysis, the incidence of ibrutinib-associated AF was 5.77 per 100 person-years, which is much higher than rates previously reported with ibrutinib and compared with the general adult population. New onset AF in cancer patients is associated with a significantly higher risk of heart failure and thromboembolism, even after adjusting for known risk factors. In addition, ibrutinib poses unique challenges due to its interactions with many medications that are commonly used to manage AF. Ibrutinib also inhibits platelet activation and decisions regarding anticoagulation have to be carefully weighed against this increased risk of bleeding. Ibrutinib's interaction with calcium channel blockers, digoxin, amiodarone, and direct oral anticoagulants can result in either ibrutinib or other drug-related toxicity and careful selection and dose adjustment may be needed. Ibrutinib-associated AF can be a therapy-limiting side effect and physicians should be familiar with the special management considerations imposed by this agent. We review the potential mechanisms and incidence of ibrutinib-associated AF and propose an algorithm for its management.

Focused cardiopulmonary ultrasound for assessment of dyspnea in a resource-limited setting.

BACKGROUND: The diagnosis and management of acutely dyspneic patients in resource-limited developing world settings poses a particular challenge. Focused cardiopulmonary ultrasound (CPUS) may assist in the emergency diagnosis and management of patients with acute dyspnea by identifying left ventricular systolic dysfunction, pericardial effusion, interstitial pulmonary edema, and pleural effusion. We sought to assess the accuracy of emergency providers performing CPUS after a training intervention in a limited-resource setting; a secondary objective was to assess the ability of CPUS to affect change of clinician diagnostic assessment and acute management in patients presenting with undifferentiated dyspnea. METHODS AND RESULTS: After a training intervention for Haitian emergency providers, patients with dyspnea presenting urgently to a regional referral center in Haiti underwent a rapid CPUS examination by the treating physician. One hundred seventeen patients (median age of 36 years, 56 % female) were prospectively evaluated with a standardized CPUS exam. Blinded expert review of ultrasound images was performed by two board certified cardiologists and one ultrasound fellowship trained emergency physician. Inter-observer agreement was determined using an agreement coefficient (kappa). Sensitivity and Specificity with confidence intervals were calculated. Pre-test and post-test clinician impressions and management plans were compared to assess for a change. We enrolled 117 patients with undifferentiated dyspnea. Upon expert image review, prevalence of left ventricular systolic dysfunction was 40.2 %, and in those with systolic dysfunction, the average EF was 14 % (±9 %). The parasternal long axis (PLAX) single view was predictive of an overall abnormal echo with PPV of abnormal PLAX 95 % and NPV 93 % of normal PLAX. Weighted kappa for pericardial effusion between the Haitian physicians and two cardiology reviewers was 0.81 (95 % CI 0.75-0.87, p value <0.001) and for ejection fraction was 0.98 (95 % CI 0.98-0.99, p value <0.001). For lung ultrasound, a kappa statistic assessing agreement between the Haitian physician and the EP for pleural effusion was 0.73, and for interstitial syndrome was 0.49. Detailed test characteristics are detailed in Table 3. Overall, there was a change in treating clinician impression in 15.4 % (95 % CI 9-22 %) and change in management in 19.6 % (95 % CI 12-27 %) of patients following CPUS. A significant structural heart disease was common: 48 % of patients were noted to have abnormal right ventricular systolic function, 36 % had at least moderate mitral regurgitation, and 7.7 % had a moderate to large pericardial effusion. CONCLUSIONS: A focused training intervention in CPUS was sufficient for providers in a limited-resource setting to accurately identify left ventricular systolic dysfunction, pericardial effusion, evidence of interstitial syndrome, and pleural effusions in dyspneic patients. Clinicians were able to integrate CPUS into their clinical impressions and management plans and reported a high level of confidence in their ultrasound findings.

Clinical characteristics of tako-tsubo cardiomyopathy.

Tako-tsubo cardiomyopathy (TTC) is increasingly diagnosed in the United States, especially in the Caucasian population. To evaluate the clinical features and outcome of patients with TTC, we evaluated 34 patients (32 women and 2 men) 22 to 88 years of age (mean 66 +/- 14) who fulfilled the following criteria: (1) akinesia or dyskinesia of the apical and/or midventricular segments of the left ventricle with regional wall motion abnormalities that extended beyond the distribution of a single epicardial vessel and (2) absence of obstructive coronary artery disease. Twenty-five patients (74%) presented with chest pain, 20 patients (59%) presented with dyspnea, and 8 patients (24%) presented with cardiogenic shock. Twenty-two patients (65%) had ST-segment elevation and 14 patients (41%) had T-wave inversion on presentation. Twenty-five patients (74%) reported a preceding stressful event. Cardiac biomarkers were often mildly increased, with a mean troponin I (peak) of 13.9 +/- 24. Mean +/- SD left ventricular ejection fractions were 28 +/- 10% at time of presentation and 51 +/- 14 at time of follow-up (p <0.0001). Two patients (6%) died during the hospital stay. Average duration of hospital stay was 6.6 +/- 6.2 days. In conclusion, TTC is common in postmenopausal women with preceding physical or emotional stress. It predominantly involves the apical portion of the left ventricle and patients with this condition have a favorable outcome with appropriate medical management. The precise cause remains unclear.

Single-center experience with the TandemHeart percutaneous ventricular assist device to support patients undergoing high-risk percutaneous coronary intervention.

UNLABELLED: We describe our experience of patients, from December 2005 through May 2007 who underwent percutaneous coronary intervention (PCI) with severely depressed left ventricle systolic function and complex coronary lesions. The complex coronary lesions included multiple vessel coronary artery disease, left main (LM) coronary artery disease, calcified coronary lesions and bypass graft disease. All patients were clinically assessed to be at too high of a risk for circulatory collapse without maximal hemodynamic support while they underwent high-risk PCI. The TandemHeart percutaneous ventricular assist device (THpVAD) may be able to provide the necessary circulatory support required to enhance procedural success and patient safety during high-risk PCI. METHODS AND RESULTS: We implanted the THpVAD in 6 patients who underwent high-risk PCI. There was unanimity among several physicians in our institution that each patient was an exceptionally high risk for circulatory collapse due to the anticipated procedural complexity. The average ejection fraction was 33% (range 15-65%). Five of the patients were considered to be at an unacceptably high risk for coronary artery bypass surgery. All 6 patients underwent multivessel PCI. Five of the 6 underwent unprotected LM PCI. One patient of the 5 underwent vein-graft PCI as well as a debulking procedure with rotational atherectomy and PCI of the LM. We had a 100% success rate with implantation of the THpVAD. Five of the 6 patients were alive at 30 days post procedure. One patient died 3 days after the procedure due to multiorgan failure. A vascular surgeon performed the removal of the devices with no associated complications. CONCLUSIONS: Our clinical experiences with the TandemHeart pVAD demonstrated that hemodynamic support could be achieved safely, efficiently and effectively by way of a percutaneous route in anticipation of high-risk PCI.
