Background
: Patients hospitalized for severe COVID-19 infection are at risk for in-hospital cardiac arrest (IHCA). It is unknown whether certain characteristics of cardiac arrest care and outcomes of IHCAs during the COVID-19 pandemic differed compared to a pre-COVID-19 period.
Methods
: All patients who experienced an IHCA at our hospital from March 1st through May 15th 2020, during the peak of the COVID-19 pandemic, and those who had an IHCA from January 1st 2019 to December 31st 2019 were identified. All patient data was extracted from our hospital's Get With The Guidelines-Resuscitation (GWTG-R) registry, a prospective hospital-based archive of IHCA data. Baseline characteristics of patients, interventions and overall outcomes of IHCAs during the COVID-19 pandemic were compared to IHCAs in 2019, prior to the COVID-19 pandemic.
Results
: There were 125 IHCAs during a 2.5-month period at our hospital during the peak of the COVID-19 pandemic compared to 117 IHCAs in all of 2019. IHCAs during the COVID-19 pandemic occurred more often on general medicine wards than in intensive care units (46% vs 33%; 19% vs 60% in 2019, p<0.001), were overall shorter in duration (median time of 11 min (8.5-26.5) vs 15 min (7.0-20.0), p=0.001), led to fewer endotracheal intubations (52% vs 85%, p<0.001) and had overall worse survival rates (3% vs 13%, p=0.007) compared to IHCAs prior to the COVID-19 pandemic.
Conclusions
: Patients who experienced an IHCA during the COVID-19 pandemic had overall worse survival compared to those who had an IHCA prior to the COVID-19 pandemic. Our findings highlight important differences between these two time periods. Further study is needed on cardiac arrest care in patients with COVID-19.
Contrast-enhanced chest computed tomography (CT) is not considered part of the evaluation of myocardial infarction. However, acute myocardial infarction has been detected on contrast-enhanced chest CT as areas of decreased myocardial enhancement in patients evaluated for other indications, such as pulmonary embolism and aortic dissection. We present a case of acute myocardial infarction on a nongated chest CT in a 67-year-old male who presented with atypical chest pain and initial nondiagnostic electrocardiogram. This case highlights that acute myocardial infarction may be detectable on contrast-enhanced CT. When evaluating contrast-enhanced chest CT's for other etiologies of chest pain, radiologists should look for potential myocardial perfusion abnormalities that can provide clues to the presence of myocardial infarction.
Cardiac sarcoidosis is a rare autoimmune condition that is characterized by the presence of non-caseating granulomas in the cardiac tissue. We present the case of a 31-year-old male with no significant past medical history who presented with palpitations and lightheadedness during exertion for two to three months and was found to have complete heart block on his 12-lead electrocardiogram. A cardiac CT was obtained to rule out an ischemic event, but it indicated findings suggestive of pulmonary sarcoidosis. The CT findings helped tremendously with narrowing down the differential diagnosis and providing efficient diagnostic and therapeutic management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
