Elevated Plasma Soluble (Pro)renin Receptor as a Potential Indicator for Heart Failure.

Translational Medicine Centre, Jiangxi University of Chinese Medicine, Nanchang 330004, China. Electronic address:
Increasing evidence has demonstrated that sPRR [a truncated soluble form of (pro)renin receptor] levels may reflect the severity of several diseases, including kidney disease, hypertension, and heart failure (HF). Although previous studies using cohorts primarily consisting of HF patients with reduced ejection fraction revealed that increased plasma sPRR levels may be a promising evaluative indicator for HF, definitive information on the relationship between plasma sPRR levels and HF patients with preserved ejection fraction (HFpEF) is still insufficient and scarce. In the present study, we further clarified the status of plasma sPRR levels in HF patients by meta-analysis.

Background: The symptom network can provide a visual insight into the symptom mechanisms. However, few study authors have explored the multidimensional symptom network of patients with atrial fibrillation (AF).
Objectives: We aimed to identify the core symptom and symptom clusters of patients with AF by generating a symptom network.
High volume-rate echocardiography for simultaneous imaging of electromechanical activation and cardiac strain of the whole heart in a single heartbeat in humans.

Background: Imaging both electrical and mechanical cardiac function can better characterize cardiac disease and improve patient care. Currently, there is no noninvasive technique that can simultaneously image both electrical and mechanical function of the whole heart at the point of care. Here, our aim is to demonstrate that high volume-rate echocardiography can simultaneously map cardiac electromechanical activation and end-systolic cardiac strain of the whole heart in a single heartbeat.

There is a controversy whether histamine H-receptor activation raises or lowers or does not affect contractility in the human heart. Therefore, we studied stimulation of H-receptors in isolated electrically stimulated (one beat per second) human atrial preparations (HAP). For comparison, we measured force of contraction in left atrial preparations (LA) from mice with overexpression of the histamine H-receptor in the heart (H-TG).
