Hace 1 día · ERNA scans detect tracer activity in the ventricular blood pool, which results in a time-activity curve, used to calculate the ejection fraction. The detected tracer activity is used to define the borders of the endocardium and derive systolic and diastolic volumes [ 2 ].
Hace 23 horas · The DanGer trial included 355 patients with STEMI and cardiogenic shock, defined as hypotension, lactic acidosis and systolic heart failure (left ventricular ejection fraction [LVEF] <45%). 3 Patients were randomized to microaxial flow pump insertion with Impella CP in addition to standard care vs. standard care alone. Patients who had shock that had been ongoing for >24 hours were excluded ...
Hace 2 días · Despite that, prompt diagnosis and prognosis of this condition are still challenging due to subtle progression and preserved left ventricular ejection fraction (LVEF) in most stages. Latest studies showed that myocardial strains could be the earliest indicator of function impairment and a good trait suggesting underlying fibrosis development.
Hace 23 horas · Heart failure (HF) with mid-range or mildly reduced ejection fraction (HFmrEF) is a separate clinical entity in the HF spectrum, with a left ventricular ejection fraction ranging from 40 to 49%. While sodium glucose co-transporter 2 inhibitors have become the cornerstone therapy for the entire HF spectrum, there are a few clinical trials of HFmrEF. This prospective observational study was ...
Hace 2 días · Left ventricular global longitudinal strain (GLS) holds greater diagnostic and prognostic value than left ventricular ejection fraction (LVEF) in the heart failure (HF) patients. The triglyceride-glucose (TyG) index serves as a reliable surrogate for insulin resistance (IR) and is strongly associated with several adverse cardiovascular events.
Hace 4 días · Ejection fraction did not significantly differ among FFs, POs, and OWs ( p > 0.6). The left ventricular mass (LV Mass) was notably higher in POs than it was in FFs ( p = 0.039) and OWs ( p =...
Hace 2 días · The left ventricular ejection fraction (LVEF) ≤ 45% met the inclusion criteria. There were three groups, including sham, model, and sacubitril/valsartan (S) groups, n = 9.
