Abstract Dynamic chest radiography (DCR) can estimate haemodynamic parameters in heart failure (HF). However, no studies have evaluated its ability to determine cardiac systolic function HF. This experimental study investigates the correlation between left ventricular (LV) ejection fraction (LVEF) and DCR image Ninety-one patients with acute HF (median age, 58 years; males, 75%) (cardiologist diagnosis using Framingham criteria) underwent transthoracic echocardiography after treatment for...
Novel coronavirus disease 2019 (COVID-19) refers to infection with the severe acute respiratory syndrome 2 (SARS-CoV-2) pathogen, and has spread pandemic levels since its inception in December 2019. While several risk factors for presentation have been identified, clinical course end-stage renal (ESRD) patients on maintenance hemodialysis COVID-19 unclear. Previous studies revealed that some antiviral agents may be effective against general population, but pharmacokinetics pharmacodynamics...
Left ventricular reverse remodelling (LVRR) is a well-established predictor of good prognosis in patients with dilated cardiomyopathy (DCM). The prediction LVRR important when developing long-term treatment strategy. This study aimed to assess the clinical predictors and establish scoring system for predicting DCM that can be used at any institution. We consecutively enrolled 131 assessed LVRR. was defined as an absolute increase left ejection fraction (LVEF) from ≥10% final value >35%,...
A 48-year-old woman suffered from cardiogenic shock with fulminant myocarditis following the second dose of COVID-19 vaccine (mRNA-1273). Venoarterial extracorporeal membrane oxygenation and Impella support were essential in achieving hemodynamic stability. Endomyocardial biopsy revealed lymphocytic infiltration predominant immunostaining for CD8- CD68-positive cells. The left ventricular ejection fraction improved significantly after treatment mechanical circulatory support. Myocarditis...
The number of older people in Japan is increasing more quickly than other countries; with this aging society, the elderly patients hospitalized for acute heart failure (HF) also increasing. treatment and prognosis HF may be changing, but there are insufficient recent data, especially octogenarian patients.
External outflow graft obstruction (OGO) in durable left ventricular assist devices (LVADs) is a rare but critical complication. Detecting external OGO can be challenging because of its nonspecific symptoms and wide variety differential diagnoses. We report the case 45 year old man with LVAD admitted complaints recurrent syncope frequent low-flow alarms. Laboratory tests chest radiography revealed no specific findings. Transthoracic echocardiography via subcostal approach an compressed by...
Despite the efficacy of many therapies for heart failure, it remains a leading cause morbidity and mortality worldwide, with patients progressing to advanced stages condition. Since standard treatment failure includes small-molecule drugs targeting G protein-coupled receptors (GPCRs), GPCRs are still considered novel targets diagnosis cardiovascular diseases. Corticotropin-releasing hormone receptor 2, highly expressed GPCR in cardiomyocytes, its ligand, urocortin2 (UCN2), have been...
Dynamic chest radiography (DCR) can estimate haemodynamic parameters in patients with heart failure (HF). Atrial fibrillation (AF) often coexists HF; however, owing to its sometimes paroxysmal nature and minimal or absent symptoms, many AF remain undiagnosed. Additional tools for diagnosis may be beneficial; therefore, we evaluated the ability of DCR distinguish HF sinus rhythm (SR) from those AF. In this small-sample pilot study, 20 (median age, 67 years; males, 85%) underwent 12-lead...
Dynamic chest radiography allows for non-invasive cardiopulmonary blood flow assessment. However, data on its use heart failure hemodynamic assessment are scarce. We utilized dynamic to estimate hemodynamics.Twenty patients (median age, 67 years; 17 men) underwent and right catheterization. The analyzed images were 16-bit (grayscale range: 0-65,535). Right atrial, pulmonary artery, left ventricular apex pixel values (average of the grayscale all pixels within a region interest) measured....
A 53-year-old woman with no significant medical history developed cardiogenic shock 4 days after receiving the second dose of COVID-19 mRNA vaccine (BNT162b2, Pfizer/BioNtech). The patient required extracorporeal membrane oxygenation and an Impella device. Based on hemoconcentration, decreased plasma protein levels, pathologic findings in myocardial specimens, was diagnosed vaccination-induced fulminant systemic capillary leak syndrome (SCLS) severe cardiac dysfunction. This case highlights...
