High-altitude pulmonary edema (HAPE) is a non-cardiogenic form of pulmonary edema, which is induced upon exposure to hypobaric hypoxia at high-altitude (HA). Hypobaric hypoxia generates reactive oxygen species that may damage telomeres and disturb normal physiological processes. Telomere complex comprises of multiple proteins, of which, tankyrase (TNKS) is actively involved in DNA damage repairs. We hence investigated the association of TNKS and telomeres with HAPE to delineate their potential role at HA. The study was performed in three groups, High altitude pulmonary edema-patients (HAPE-p, n = 200), HAPE-resistant sojourners (HAPE-r, n = 200), and healthy-highlanders (HLs, n = 200)...

PURPOSE: During acute ischemic stroke evaluations, neurovascular imaging is commonly performed to localize the source of a thromboembolus and to identify vascular stenoses. In this study, we aimed to analyze 1) the usefulness of intracranial and/or cervical CTA and MRA and carotid doppler ultrasound (DUS) for identifying the stroke source and 2) the incidence of vascular stenoses across stroke etiologies. METHODS: We retrospectively reviewed intracranial and/or cervical CTA, DUS and MRA studies to identify the source of the acute stroke by Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria for 200 consecutive patients admitted with a stroke to our tertiary hospital...

Acute respiratory failure is a complex physiopathological process and the choice of the most appropriate therapy has to be made between standard oxygen therapy (SOT), high-flow oxygen therapy through nasal cannula (High-Flow Nasal Cannula (HFNC)), non- invasive ventilation (NIV) or invasive ventilation. HFNC can deliver a higher and consistent inspired fraction of oxygen than SOT, but has not clearly demonstrated a clinical advantage over other methods. NIV is a therapy of choice in the management of acute exacerbation of chronic obstructive pulmonary disease and acute cardiogenic pulmonary edema, but its effectiveness in other indications is questionable...

Background: More than half of the patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) have multi-vessel coronary artery disease. This is associated with worse outcomes compared with single vessel disease. Whilst evidence now exists to support complete revascularisation for bystander disease the optimal timing is still debated. This study aimed to compare clinical outcomes in patients with STEMI and multi-vessel disease who underwent complete revascularisation as inpatients in comparison to patients who had staged PCI as early outpatients...

AIMS: Age is an important risk factor for mortality among patients with cardiogenic shock and heart failure (HF). We sought to assess the extent to which age modified the performance of the Society for Cardiovascular Angiography and Interventions (SCAI) shock stage for in-hospital and 1 year mortality in cardiac intensive care unit (CICU) patients with and without HF. METHODS AND RESULTS: We retrospectively reviewed unique admissions to the Mayo Clinic CICU during 2007-2015 and stratified patients by age and SCAI shock stage...

Elevated cardiac enzymes are often seen in the setting of sepsis. The mechanism involves hypoperfusion and possible compromise to myocardial tissue. Electrocardiogram (ECG) changes in the setting of septic shock are less common and can vary widely. Rarely, ST-segment elevations can occur. This case describes a 54-year-old female who presented with septic shock secondary to pyelonephritis and Escherichia coli bacteremia. The patient was admitted to the intensive care unit on norepinephrine and required mechanical ventilation...

Myocarditis is an unusual manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has been associated with increased severity of disease and mortality. The diagnosis of coronavirus disease 2019 (COVID-19) is based on positivity of nucleic acid amplification tests (NAAT) of respiratory samples. We report the case of a patient with cardiogenic shock caused by SARS-CoV-2 myocarditis with serial negative upper and lower respiratory nucleic acid amplification tests. Diagnosis was made by serology (positive IgM + IgA and IgG) from patient's serum sample of day 10 after symptoms' initiation...

Heart failure is characterized by pathologic hemodynamic derangements, including elevated cardiac filling pressures ("backward" failure), which may or may not coexist with reduced cardiac output ("forward" failure). Even when normal during unstressed conditions such as rest, hemodynamics classically become abnormal during stressors such as exercise in patients with heart failure. This has important upstream and downstream effects on multiple organ systems, particularly with respect to the lungs and kidneys...

A 50-year-old woman underwent coronary artery bypass graft (CABG) for multivessel coronary artery disease. Due to hemodynamic instability, the patient could not be weaned from cardiopulmonary bypass without mechanical support, even after multiple attempts. Subsequently, a right ventricular intramyocardial hematoma (IH) was found during postoperative coronary angiography. The IH was felt to be the main contributing factor leading to right ventricular failure and cardiogenic shock, which, to the authors' knowledge, has not been previously reported after CABG...

AIMS: Critical culprit lesion locations (CCLL) such as left main (LM) and proximal left anterior descending (LAD) are associated with worse clinical outcome in myocardial infarction without cardiogenic shock (CS). We aimed to assess whether CCLL identifies a subgroup of patients at poorer prognosis when presenting with CS. METHODS AND RESULTS: In the CULPRIT-SHOCK trial, a core-laboratory reviewed all coronary angiograms to identify CCLL. CCLL was defined as a culprit lesion realizing a >70% diameter stenosis of LM, LM equivalent (>70% diameter stenoses of both proximal LAD and proximal circumflex), proximal LAD or, last remaining vessel...

We describe four cases of spinal cord ischemia resulting in paraplegia after peripheral venoarterial extracorporeal membrane oxygenation for cardiogenic shock. This is an uncommon, but possibly underreported, complication with significant irreversible long-term morbidity. While causes are likely multifactorial, it is possible that thrombosis may occur at the level of the mixing cloud due to turbulent flow. Additional studies will be needed to elucidate the true incidence of this complication and investigate whether flow dynamics may potentiate clot formation...

BACKGROUND: Bleeding is a common complication of percutaneous coronary intervention (PCI) that is associated with worse clinical outcomes and increased costs. Improved pre-procedural bleeding risk prediction could promote strategies that have been shown to reduce post-PCI bleeding, including increased adoption of radial access. METHODS: We studied patients in the Veterans Affairs Clinical Assessment, Reporting, and Tracking (VA CART) program receiving PCI in VA hospitals...
