Functional Significance of Cardiac Rehabilitation-Regulated Expression of Circulating MicroRNA-423-5p in Hypertensive Patients with Heart Failure with a Moderately Reduced Ejection Fraction

Anatolian Journal of Cardiology, 2022
Background: Hypertension is a vital risk factor for heart failure, while cardiac rehabilitation can effectively improve cardiac function of heart failure patients.

Dynamics of conduction blocks in a model of paced cardiac tissue [PDF]

, 2005
We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region.

Central command suppresses pressor‐evoked bradycardia at the onset of voluntary standing up in conscious cats

Experimental Physiology, 2023
It remains unclear whether cardiac baroreflex function is preserved or suppressed at the onset of standing up. To answer the question and, if cardiac baroreflex is suppressed, to investigate the mechanism responsible for the suppression, we compared the ...

Exploring the diagnostic and prognostic value of the C-reactive protein/lymphocyte ratio for dilated cardiomyopathy based on a real-world study

Scientific Reports, 2023
To determine the risk factors for dilated cardiomyopathy (DCM) and construct a risk model for predicting HF in patients with DCM, We enrolled a total of 2122 patients, excluding those who did not meet the requirements.

Abnormal Myocardial Blood Flow Reserve Observed in Cardiac Amyloidosis [PDF]

, 2016
We performed real-time myocardial contrast echocardiography on a patient with cardiac amyloidosis and previous normal coronary angiography presenting with atypical chest pain to assess myocardial blood flow reserve (MBFR).

Efficient fetal-maternal ECG signal separation from two channel maternal abdominal ECG via diffusion-based channel selection

, 2017
There is a need for affordable, widely deployable maternal-fetal ECG monitors to improve maternal and fetal health during pregnancy and delivery. Based on the diffusion-based channel selection, here we present the mathematical formalism and clinical ...

Preoperative sST2 levels relate to myocardial remodeling and cardiac function improvement after cardiac valve surgery

ESC Heart Failure
Aims We aim to investigate the correlation between preoperative soluble suppression of tumourigenicity 2 (sST2) and postoperative myocardial remodelling and cardiac function in patients with valvular heart disease.
