ABSTRACT
Background Graft versus host disease (GVHD) most often occurs 100-365 days after hematopoietic stem cell transplant (HSCT). Manifestations most often are dermatologic, hepatic or pulmonic, and are rarely cardiac. We present a unique case of GVHD inducing cardiogenic shock necessitating advanced heart failure therapies. Case This is a 34 year-old male with a history of acute lymphoblastic leukemia who completed chemoradiation and HSCT from an HLA perfect sibling in 1992. In May 2020, he presented with dyspnea for 6 weeks. An echocardiogram at that time showed an EF of 10% and severe biventricular dilatation. He was originally hospitalized at an outside institution for hypoxia where a left heart catheterization showed normal coronaries and goal directed therapy was initiated. After 2 negative COVID tests, he was discharged with a LifeVest. One month later, despite medication compliance, he returned in cardiogenic shock after his LifeVest was activated for ventricular tachycardia (VT). Decision-making He was started on inotropic therapy and an intra-aortic balloon pump (IABP) was placed 1:1 prior to transfer to our tertiary center. After support was started, a right heart catheterization showed a right atrial pressure of 13 mmHg, a wedge of 17, and a cardiac index of 2.6. His course was complicated by VT storm. Differentials for his non-ischemic cardiomyopathy (NICMO) included myocarditis (viral vs. giant cell) with a possible component of chemotherapy/radiation induced NICMO. Immediate AHFT work-up was started. He was unable to be weaned off his IABP or inotropic support. The decision was made to pursue emergent left ventricular assist device placement (LVAD) and achieve a definitive diagnosis with a core biopsy. Pathology resulted with myocyte hypertrophy, chronic inflammation with eosinophils concerning for chronic GVHD. Conclusion There have only been a handful of case reports describing cardiac manifestations of GVHD, and none with NICMO and cardiogenic shock requiring an LVAD. Despite this, suspicion should remain present for GVHD in HSCT patients regardless of time frame from oncologic therapies or specificity of HLA match when presenting in cardiogenic shock.Copyright © 2023 American College of Cardiology Foundation
ABSTRACT
Aim: To assess the impact of the 2020 coronavirus disease (COVID-19) pandemic on the prehospital characteristics and outcomes of out-of-hospital cardiac arrest (OHCA) in the elderly. Methods: In this population-based nationwide observational study in Japan, 563,100 emergency medical service-unwitnessed OHCAs in elderly (≥65 years) patients involving any prehospital resuscitation efforts were analysed (144,756, 140,741, 140,610, and 136,993 cases in 2020, 2019, 2018, and 2017, respectively). The epidemiology, characteristics, and outcomes associated with OHCAs in elderly patients were compared between 3 years pre-pandemic (2017-2019) and the pandemic year (2020). The primary outcome was neurologically favourable one-month survival. The secondary outcomes were the rate of bystander cardiopulmonary resuscitation (CPR), defibrillation by a bystander, dispatcher-assisted (DA)-CPR attempts, and one-month survival. Results: During the pandemic year, the rates of neurologically favourable 1-month survival (crude odds ratio, 95% confidence interval: 1.19, 1.14-1.25), bystander CPR (1.04, 1.03-1.06), and DA-CPR attempts (1.10, 1.08-1.11) increased, whereas the incidence of public access defibrillation (0.88, 0.83-0.93) decreased. Subgroup analyses based on interaction tests showed that the increased rate of neurologically favourable survival during the pandemic year was enhanced in OHCA at care facilities (1.51, 1.36-1.68) and diminished or abolished on state-of-emergency days (0.90, 0.74-1.09), in the mainly affected prefectures (1.08, 1.01-1.15), and in cases with shockable initial rhythms (1.03, 0.96-1.12). Conclusions: The COVID-19 pandemic increased the bystander CPR rate in association with enhanced DA-CPR attempts and improved the outcomes of elderly patients with OHCAs.
ABSTRACT
Background: Regional variations in the impact of the coronavirus disease-2019 (COVID-19) pandemic on out-of-hospital cardiac arrest (OHCA) have been reported. We aimed to examine differences in the community response, emergency medical services (EMS) interventions, and outcomes of OHCA, in Singapore (population 5.7 million) and Atlanta (population 4.16 million), before and during the pandemic. Methods: Using prospectively collected Singapore Pan-Asian Resuscitation Outcomes Study (PAROS) and Atlanta Cardiac Arrest Registry to Enhance Survival (CARES) data, we compared EMS-treated adult OHCAs (≥18 years) during the pandemic period (17weeks from the date of first confirmed COVID-19 case) and pre-pandemic period (corresponding weeks in 2019). The primary outcome was pre-hospital return of spontaneous circulation (ROSC). We reported adjusted odds ratios (aOR) for OHCA characteristics, pre-hospital interventions, and outcomes using binary logistic regression. Results: Of the 3987 EMS-treated OHCAs (overall median age 69 years, 60.1% males) in Singapore and Atlanta, 2084 occurred during the pandemic and 1903 during the pre-pandemic period. Compared with Atlanta, OHCA cases in Singapore were older (median age 72 vs 66 years), received more bystander interventions (65.1% vs 41.4% received cardiopulmonary resuscitation (CPR) and 28.4% vs 10.1% had automated external defibrillator application), yet observed less pre-hospital ROSC (11.3% vs 27.1%). When compared with the pre-pandemic period, the likelihood of residential OHCAs doubled in both cities during the pandemic;in Singapore, OHCAs were more likely to be witnessed (aOR 1.95, 95% confidence interval (CI), 1.59-2.39) yet less likely to receive CPR (aOR 0.81, 95% CI, 0.65-0.99) during the pandemic. OHCAs occurring during the pandemic, compared with pre-pandemic, were less likely to be transported in Singapore and Atlanta (aOR 0.50, 95% CI, 0.42%-0.85%, and 0.36, 95% CI, 0.26-0.50, respectively), without significant differences in overall pre-hospital ROSC. Conclusion: Changes in OHCA characteristics and pre-hospital interventions during the pandemic were likely collateral consequences, with regional variations partly reflecting differences in systems of care and other sociocultural factors. These highlight opportunities for public education and the need for further study into lower transport rates during the pandemic.
ABSTRACT
Background: Underlying mechanisms for sport-related acute myocardial infarction (SR-AMI) are only poorly understood. Moreover, their coronary artery disease (CAD) characteristics and lesion complexity are poorly described. Purpose: To characterize coronary angiographic feature of patients with SR-AMI Methods: From the RICO database, a large regional acute MI survey, all consecutive patients hospitalized in our University Hospital from 2010 to 2021 who underwent coronary angiography for SR-MI were retrospectively analysed. SR-MI was defined as MI occurring during sport activity or within the first hour of recovery. Results: Among the 174 patients included, most were male (n=157(91%)). Median (IQR) age was 59 y (48-66), and had ST segment elevation MI (STEMI) (n= 112 (64%)). The SR-MI often occurred while cycling (41%), jogging (23%), hiking (9%) or playing soccer (9%). Patients commonly experienced pre-hospital (PH) sudden cardiac arrest (SCA) (17%). Atherothrombotic risk factors were dyslipidaemia (32%), current smoking (31%) or hypertension (28%). A history of CAD was documented in 31 (18%) patients. Most (n=156(91%)) had significant lesions, of whom 140 (81%) were considered as culprit. Culprit lesions were located on left anterior descending (39%), circumflex (14%) and right coronary artery (33%). Median (IQR) Syntax score was 10.5 (6-15). The vast majority of patients (n=152 (87%)) had at least one complex lesion;114 of them had several characteristics of complex lesion. Lesions were eccentric in 68 (39%) patients;an intraluminal thrombus was documented in 85 patients (49%), in 55% of STEMI and 37% of non-STEMI (p =0.027). However, 18 subjects (10%) had optically normal coronary angiogram or non-significant lesions, suggesting alternative mechanism such as type 2 MI. Treatment of the lesions was mainly achieved by PCI and/or stenting (n=132(77%)) or coronary artery bypass grafting (n=11(6%)). In-hospital death occurred in 11 patients (6%), of whom 10 experienced a PH-SCA and one was admitted with a cardiogenic shock during the Covid-19 pandemics lockdown. Among the 5 patients treated with extracorporeal membrane oxygenator, only one survived. Conclusion: In our large retrospective study, SR-MI was commonly associated with complex coronary lesions, often characterized by intraluminal thrombus. Our findings suggest that the mechanisms of these events could be mainly related to type 1 MI patterns Moreover, PH-SCA was frequent, thus justifying mass-education to basic life support and deployment of automated external defibrillators, especially in the sport settings.
ABSTRACT
Background: The CMS Hospital at Home (H@H) program during the COVID 19 pandemic was successfully applied as a suitable alternative to unnecessary admissions in lower risk patient populations. As the top 5% pts ($50,000/Year) account for 50% of the US healthcare expenditure over 15 years (5:50 Rule), we sought to investigate the long-term clinical and financial effectiveness and sustainability of new model of home hospital and critical care (H2C2) on the top 5% patients. Methods: 68 consecutive pts with top 5% annual cost profile (~4 admissions/pt with severe chronic dx [CHF, CAD, CODP, sepsis] +/-ventilator, PEG, dialysis, LifeVest) were enrolled in a multiple MSO program. On-site & On-line care started 3/2019 via patented processes and individualized protocols/devices (24/7 monitoring + ICU level Telemetry, 12-lead ECG). All Medicare Part A, B & D costs, admissions and LOS for pts were computed and normalized per phase (PRIOR, DURING, POST H2C2) to determine effectiveness and sustainability. Results: Of the 68 patients, 90% discharged to PCP, 6% admitted to hospice and 4% remained on the program for continuous care. There were no deaths at home. Compared to baseline, H2C2 had an over 70% sustained total cost reduction. Conclusion: This is 1st study to assess long-term clinical & financial impacts of H2C2 in top 5% of high-risk/cost pts. H2C2 was safe with a significantly sustained reduction of admissions and costs both during and 1.5 years post H2C2. Further studies are warranted for scalability. [Formula presented]
ABSTRACT
Objectives: To analyse the incidence of emergency medical serviceattended out-of-hospital cardiac arrests (OHCAs) and prehospital return of spontaneous circulation (ROSC) outcomes in Singapore from January to May 2020, as compared to the same period in 2018 and 2019. Methods: This was a retrospective observational study comparing current and previous emergency medical service (EMS) data and OHCA records maintained by the Singapore Civil Defence Force (SCDF). These figures were tabulated from data input by experienced paramedics responding to EMS calls and verified by an internal audit team. The study was conducted in accordance with the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) guidelines, and examined factors that may have contributed to an increase or decrease in OHCA incidence and prehospital ROSC attainments during the different time periods. Results: Coronavirus Disease 2019 (COVID-19) is a global pandemic of unparalleled scale. Despite total EMS call volumes and overall OHCA incidence remaining comparable to pre-COVID periods, there was a concerning decrease in pre-hospital ROSC attainments between January to May 2020 (an average of 8.4%). Based on multivariable logistic regression, this was much lower when compared to previous years, where the pre-hospital ROSC rates remained around 12% (p<0.001). Further analyses did not reveal significant differences in terms of the median age of OHCA victims, the percentage of shockable rhythm or response times. However, it was noted that more OHCAs were occurring in residential homes, while those in public spaces decreased considerably compared to previous years (p<0.001). In addition, there was also a drop in the overall bystander cardiopulmonary resuscitation (CPR) rates compared to pre-COVID periods (p<0.001). Conclusion: The findings remain preliminary and follow-up data in the subsequent months are necessary to further investigate these trends. Nonetheless, they provide important lessons for public education and pandemic preparedness. To strengthen the first links in the survival chain, members of the public should be educated to initiate CPR and automated external defibrillator (AED) for any non-responsive victim (even without mouth-to-mouth ventilation).
