Relationship between cachexia and short physical performance battery scores in patients with heart failure attending comprehensive outpatient cardiac rehabilitation.

Heart failure (HF) can cause metabolic imbalances, leading to anabolic resistance and increased energy expenditure, which often results in weight loss and cachexia. Comprehensive cardiac rehabilitation (CR), including exercise, nutritional support, and risk management, is crucial for enhancing the health and quality of life of patients with HF and is expected to play a central role in the prevention and treatment of HF-associated cachexia. However, the prevalence of cachexia in patients with HF undergoing comprehensive outpatient CR is currently unknown, and the detailed characteristics including of motor function of such patients remain undefined.

Trajectories of frailty, physical function, and physical activity levels in elderly patients with heart failure: impacts of interruption and resumption of outpatient cardiac rehabilitation due to COVID-19.

During the nationwide state of emergency, many hospitals could not provide outpatient cardiac rehabilitation for cardiac disease patients in order to minimize coronavirus disease 2019 (COVID-19) incidence. The purpose of this study was to examine the trajectories of frailty, physical function and physical activity levels due to interruption and resumption of outpatient cardiac rehabilitation by COVID-19 in elderly heart failure patients. Fifteen patients who did not attend outpatient cardiac rehabilitation during the state of emergency but resumed it after the state of emergency were included.

Differences in pharmacological property between combined therapy of the vasopressin V2-receptor antagonist tolvaptan plus furosemide and monotherapy of furosemide in patients with hospitalized heart failure.

Background: Tolvaptan has been shown to improve congestion in heart failure patients. The purpose of this study was to evaluate the pharmacology and clinical efficacy of combined tolvaptan and furosemide therapy.

Methods: This study included 40 patients with systemic volume overload who were hospitalized for heart failure.

Clinical significance of arterial stiffness as a factor for hospitalization of heart failure with preserved left ventricular ejection fraction: a retrospective matched case-control study.

Background: Previous studies have been conducted to identify characteristics of patients with heart failure with preserved ejection fraction (HFpEF), but the risk factors of HFpEF remain unclear. We investigated the associations between arterial stiffness and the risk of hospitalization for HFpEF patients.

Methods: For the case group, we enrolled patients with preserved EF who had been hospitalized for HF from April 2013 to March 2015 and examined the cardio-ankle vascular index (CAVI).

Effects of tolvaptan on urine output in hospitalized heart failure patients with hypoalbuminemia or proteinuria.

Hypoalbuminemia is an independent prognostic factor in hospitalization for heart failure (HHF). Hypoalbuminemia or proteinuria is related to resistance to loop diuretics. Tolvaptan is an oral non-peptide, competitive antagonist of vasopressin receptor-2.

Clinical usefulness of gated technetium-99m sestamibi myocardial perfusion single-photon emission computed tomography with phase analysis for the management of patients with isolated ventricular noncompaction.

Gated Tc-99m sestamibi myocardial perfusion single-photon emission computed tomography (GMPS) with phase analysis provides information on myocardial perfusion, left ventricular (LV) function, and LV dyssynchrony. We present a case of isolated left ventricular noncompaction (IVNC) cardiomyopathy in which GMPS with phase analysis proved to be beneficial and reliable to monitor the long-term response to cardiac resynchronization therapy with defibrillator (CRT-D). The patient was an 84-year-old man with shortness of breath on minimal exertion (New York Heart Association class III) who had severe drug-refractory heart failure with hypotension and ventricular tachycardia.
