Diuretic Potentiation Strategies in Acute Heart Failure.

Several trials have evaluated diuretic-based strategies to improve symptoms and outcomes in patients with acute heart failure (AHF). The authors sought to summarize the effect of different combination strategies on symptoms, physical signs, physiological variables, and outcomes in patients with AHF. Twelve trials were identified that assessed the addition of thiazide diuretics, sodium-glucose cotransporter 2 inhibitors, mineralocorticoid receptor antagonists, vasopressin receptor antagonists, carbonic anhydrase inhibitors, or loop diuretic intensification to conventional therapy for AHF.

Development and validation of animal variant classification guidelines to objectively evaluate genetic variant pathogenicity in domestic animals.

Assessing the pathogenicity of a disease-associated genetic variant in animals accurately is vital, both on a population and individual scale. At the population level, breeding decisions based on invalid DNA tests can lead to the incorrect inclusion or exclusion of animals and compromise the long-term health of a population, and at the level of the individual animal, lead to incorrect treatment and even life-ending decisions. Criteria to determine pathogenicity are not standardized, i.

Performance of Clinical Scoring Systems in the Diagnosis of Transthyretin Amyloid Cardiomyopathy in a Diverse Patient Cohort.

Background: Two diagnostic clinical scoring systems, the ATTR-CM Score and the T-AMYLO Score, have been proposed but not validated in diverse populations, despite Black race being an important risk factor for transthyretin amyloid cardiomyopathy (ATTR-CM). The aim of this study was to evaluate their performance in diagnosing ATTR-CM in a diverse patient cohort.

Methods: This retrospective single-center study analyzed patients who underwent a 99mTc-pyrophosphate single photon emission computed tomography scan (Tc-PYP) for workup of suspected ATTR-CM.

The Prognostic Role of Pulmonary Arterial Elastance in Patients Undergoing Left Ventricular Assist Device Implantation: A Pilot Study.

: Pulmonary arterial elastance (Ea) is a helpful parameter to predict the risk of acute postoperative right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation. A new method for calculating Ea, obtained by the ratio between transpulmonary gradient and stroke volume (Ea), has been proposed as a more accurate measure than the Ea obtained as the ratio between pulmonary artery systolic pressure and stroke volume (Ea). However, the role of Ea in predicting acute RVF post-LVAD implantation remains unclear.
