Relationship between the HeartMate Risk Score category on admission and outcome in patients with acute heart failure referred to a cardiac intensive care unit.

The HeartMate Risk Score (HMRS), a simple clinical prediction rule based on the patients' age, albumin, creatinine, and the international normalized ratio of the prothrombin time (PT-INR), is correlated with mortality in the cohort of left ventricular assist device (LVAD) recipients. However, in an aging society, an LAVD is indicated for only a small proportion of patients with acute heart failure (AHF), and whether the HMRS has prognostic implications for unselected patients with AHF is unknown. This study aimed to assess the prognostic value of HMRS categories on admission in patients with AHF.

Impella Motor Current Amplitude Reflects the Degree of Left Ventricular Unloading under ECPELLA Support.

The combination of venoarterial extracorporeal membrane oxygenation (VA-ECMO) and Impella, referred to as ECPELLA, is a powerful transient mechanical circulatory support for patients with severe cardiogenic shock (CS). During ECPELLA support, VA-ECMO loads the left ventricle (LV) and Impella unloads the LV. Therefore, evaluating the degree of LV unloading during ECPELLA may be a prerequisite to protect the injured myocardium.

Prognostic Impact of Landiolol in Patients with Acute Heart Failure and Atrial Fibrillation with Rapid Ventricular Rates: A Pilot Observational Study.

Introduction: Guidelines recommend ventricular rate control to <130 bpm during atrial fibrillation (AF) in patients with acute decompensated heart failure (ADHF) to avoid aggravating deteriorations in cardiac outputs. We aimed to evaluate the prognostic impact of landiolol in patients with ADHF and AF.

Methods: This observational study included 60 patients who were urgently hospitalized with ADHF and presented with AF and a heart rate (HR) ≥130 bpm at admission.

Left ventricular systolic function affects right atrial pressure as prognosticator in patients with heart failure.

The effect of the left ventricular ejection fraction (LVEF) on the prognostic impact of the right atrial pressure (RAP) in patients with heart failure (HF) requires clarification. We aimed to investigate whether LVEF affects the prognostic impact of RAP estimated from inferior vena cava (IVC) measurements in patients hospitalized with HF. Initially, this observational study included 1349 consecutive patients urgently hospitalized with HF.

Prognostic impact of right ventricular function affected by pulmonary hypertension in hospitalized heart failure patients.

Background: Pulmonary hypertension (PH) may affect right ventricular (RV) function; however, the prognostic implications of RV function in patients with heart failure and PH remain unclear. We aimed to investigate the impact of RV function on the prognosis of hospitalized heart failure patients with and without PH.

Methods: This observational study initially included 1,349 consecutive hospitalized heart failure patients.

Predictors of hypoxemia in type-B acute aortic syndrome: a retrospective study.

Acute aortic syndrome (AAS) can be life-threatening owing to a variety of complications, and it is managed in the intensive care unit (ICU). Although Stanford type-B AAS may involve hypoxemia, its predictors are not yet clearly understood. We studied clinical factors and imaging parameters for predicting hypoxemia after the onset of type-B AAS.

Increased and continuous coronary arterial flow was induced by LV uncoupling condition using combined treatment of a microaxial heart pump and venoarterial extracorporeal membrane oxygenation.

An emerging therapeutic modality, ECPELLA, which combines a transvalvular microaxial left ventricular (LV) assist device, Impella, and venoarterial membrane oxygenation (VA-ECMO), has been applied for patients with refractory cardiogenic shock. During ECPELLA support, VA-ECMO increases the LV load, whereas the Impella reduces the LV load. Studies reported that coronary perfusion is influenced by LV unloading conditions, and the effective degree of LV unloading to increase the coronary perfusion on ECPELLA support remains to be determined.

Prognostic impact of additional mineralocorticoid receptor antagonists in octogenarian heart failure patients.

Aims: Guideline-directed medical therapy (GDMT) including beta-blockers and renin-angiotensin system inhibitors is shown to reduce mortality risk in patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF). However, there is little evidence about the efficacy of additional administration of mineralocorticoid receptor antagonists (MRAs) with GDMT in patients ≥80 years presenting with HF. We aimed to investigate the prognostic impact of GDMT with MRA in relation to the age of patients with HF.
