Relationship between abnormal P-wave terminal force in lead V1 and left ventricular diastolic dysfunction in hypertensive patients: the LIFE study

open access: yesBlood Pressure, 2017
Background: Abnormal P-wave terminal force in lead V1 (PTF-V1) is an ECG marker of increased left atrial (LA) volume, elevated LA filling pressures and/or LA systolic dysfunction.

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Optimal phase for coronary interpretations and correlation of ejection fraction using late-diastole and end-diastole imaging in cardiac computed tomography angiography: implications for prospective triggering

open access: yesThe International Journal of Cardiovascular Imaging, 2009
A typical acquisition protocol for multi-row detector computed tomography (MDCT) angiography is to obtain all phases of the cardiac cycle, allowing calculation of ejection fraction (EF) simultaneously with plaque burden.

DNA‐PKcs‐Driven YAP1 Phosphorylation and Nuclear Translocation: a Key Regulator of Ferroptosis in Hyperglycemia‐Induced Cardiac Dysfunction in Type 1 Diabetes

open access: yesAdvanced Science, EarlyView.
In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.

Exploring the limitations of blood pressure estimation using the photoplethysmography signal [PDF]

open access: yes
Hypertension, a leading contributor to cardiovascular morbidity, underscores the need for accurate and continuous blood pressure (BP) monitoring. Photoplethysmography (PPG) presents a promising approach to this end. However, the precision of BP estimates derived from PPG signals has been the subject of ongoing debate, necessitating a comprehensive ...

KLF1 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through Regulation of Wnt/β‐Catenin Signaling Pathway

open access: yesAdvanced Science, EarlyView.
In KLF1‐on (neonatal and Klf1 overexpression hearts) models, KLF1 regulates Wnt/β‐catenin signaling pathway and the expression of cell proliferation‐related genes via transcriptional and epigenetic mechanisms, which induces cardiomyocyte proliferation and cardiac regeneration in mice after myocardial infarction.

P6.11 EVALUATION OF A NOVEL AND EXISTING TECHNIQUES FOR THE ESTIMATION OF PULSE TRANSIT TIME

open access: yesArtery Research, 2013
The method used for pulse transit time (PTT) estimation, affects critically the accuracy of pulse wave velocity (PWV) measurements. The existing methods for PTT estimation yield often substantially different PWV values.
