Effect of heart rate on B-type natriuretic peptide in sinus rhythm.
Sci Rep

B-type natriuretic peptide (BNP) levels accurately reflect the degree of cardiac overload in heart failure. Considering cardiac morphology and intracardiac pressure, including the left ventricular end-systolic volume index (LVESVI) and left ventricular end-diastolic volume index (LVEDVI), is essential for cardiac overload assessment. These indexes influence plasma BNP levels, and high heart rate is likely associated with cardiac morphology.

This study tested the safety, tolerability and pharmacokinetics of this novel therapeutic option. REMOTE-HF was a multicenter, double-blind, randomized, placebo-controlled, phase Ib dose-titration study with two active arms.

Ethnopharmacological Relevance: Ischemic stroke (IS) is a major cause of mortality. Inflammation exerts an essential part of brain-heart communication after IS. Naoxintong capsules (NXT), derived from the classical Traditional Chinese Medicine (TCM) formulation Bu-Yang-Huan-Wu-Tang, are extensively employed in China to manage IS, myocardial infarction (MI), and atherosclerosis.

Heart failure (HF) in children is a complex syndrome with multiple diverse etiologies and both acute and chronic presentations. Chronic presentations can persist throughout childhood and adolescence, and require diligent management with ongoing reassessment to maximize survival and quality of life. Stages of HF are key to recognize as they guide both management and inform prognosis.

Auckland Bioengineering Institute, The University of Auckland, Auckland, New Zealand.
Cardiac sex-difference functional studies have centred on measurements of twitch force and Ca dynamics. The energy expenditures from these two cellular processes: activation (Ca handling) and contraction (cross-bridge cycling), have not been assessed, and compared, between sexes. Whole-heart studies measuring oxygen consumption do not directly measure the energy expenditure of these activation-contraction processes.
