Loss of Na⁺,HCO₃ ^--Cotransporter NBCn1 Inhibits Net Acid Extrusion in the Atria and Causes Hypertension-Associated Cardiac Hypertrophy. [PDF]

Acta Physiol (Oxf)
ABSTRACT Aim Metabolic disturbances challenge pH homeostasis in cardiomyocytes. The electroneutral Na+,HCO3−‐cotransporter NBCn1/Slc4a7 mediates net acid extrusion, and genetic variation in SLC4A7 contributes to human hypertension and cardiovascular risk.

The Role of Right Ventricular Embryology in Echocardiographic Assessment of RV Function. [PDF]

Echocardiography
This review highlights how the embryologic segmentation of the right ventricle informs echocardiographic assessment, linking each anatomical compartment to specific imaging modalities. Understanding these developmental foundations enhances the accuracy of RV functional evaluation in both congenital and acquired heart disease.

Cardiovascular function in women with previous gestational diabetes mellitus and dysglycemia at 5 months postpartum. [PDF]

Ultrasound Obstet Gynecol
ABSTRACT Objective To examine the cardiovascular profile of women at 5 months postpartum who developed gestational diabetes mellitus (GDM), and to determine whether this profile differs between those with dysglycemia and those who are normoglycemic. Methods A postnatal follow‐up clinic was attended by 770 women who developed GDM.

Alterations of myocardial ketone metabolism in heart failure with preserved ejection fraction (HFpEF). [PDF]

ESC Heart Fail
Abstract Introduction Cardiac energy metabolism is disrupted in heart failure with preserved ejection fraction (HFpEF), as characterized by a switch from glucose oxidation towards fatty acid oxidation. However, although oxidation of ketones is an important source of ATP it remains unclear how the heart oxidizes ketones in HFpEF.

Comparison of hypertensive patients with left ventricular hypertrophy versus hypertensive patients without left ventricular hypertrophy using echocardiography and tissue doppler imaging

Al-Azhar Assiut Medical Journal, 2021
Background and aim Systemic hypertension (SH) causes a gradual increase in the mass of the left ventricle, resulting in left ventricular hypertrophy (LVH).
