Although resting hemodynamic load has been extensively investigated as a determinant of left ventricular (LV) hypertrophy, little is known about the relationship between provoked hemodynamic load and the risk of LV hypertrophy. We studied central pressure-flow relations among 40 hypertensive and 19 normotensive adults using carotid applanation tonometry and Doppler echocardiography at rest and ...

Some of the several effects sodium-glucose cotransporter-2 inhibitors (SGLT-2i), including their metabolic, anti-inflammatory and hemodynamic properties, along with other kidney protective values, have directed clinicians to give these drugs in IgA-nephropathy (IgAN). According recent studies regarding beneficial SGLT-2i on IgAN, it is clear that are changing approach towards transplantation wh...

BACKGROUND Pressure contour analysis is commonly used to estimate cardiac performance for patients suffering from cardiovascular dysfunction in the intensive care unit. However, the existing techniques for continuous estimation of stroke volume (SV) from pressure measurement can be unreliable during hemodynamic instability, which is inevitable for patients requiring significant treatment. For t...

Background: Clinical investigations have reported several anesthetic properties of intrathecal injections of meperidine. The purpose of this study was to investigate the effect of adding meperidine to intrathecal heavy lidocaine on hemodynamic changes and blood loss in patients undergoing elective suprapubic open prostatectomy. Methods: In a randomized double-blind clinical trial, 77 pa...

The significance of accurate knowledge of background optical properties and time-resolved information in reconstructing images of hemodynamic changes in the neonatal brain from diffuse optical imaging data was studied using Monte Carlo (MC) simulation. A segmented anatomical magnetic resonance (MR) image and literature-derived optical properties for each tissue type were used to create a voxel-...

Embryonic heart formation results from a dynamic interplay between genetic and environmental factors. Blood flow during early embryonic stages plays a critical role in heart development, as interactions between flow and cardiac tissues generate biomechanical forces that modulate cardiac growth and remodeling. Normal hemodynamic conditions are essential for proper cardiac development, while alte...

Introduction: Hospitalization in the cardiac care unit (CCU) is a stressful event that can adversely affect the patient's recovery process. Another factor that may be affected by stress is hemodynamic indices. The aim of this study was to determine the effect of stress on hemodynamic indices in patients admitted to the CCU. Materials and Methods: The present study is a descriptive correlational...

A prompt behavioral response to a stimulus depends both on the salience of the stimulus as well as the subject's preparedness. Thus, both stimulus properties and cognitive factors, such as attention, may determine the strength of neuronal synchronization in the gamma range. For a comprehensive investigation of stimulus-response processing through noninvasive imaging, it is, however, a crucial i...

conclusions combination of propofol-ketamine may be recommended as an effective and safe induction agent for attenuating hemodynamic responses to laryngoscopy and intubation with better hemodynamic stability. although, further well-designed randomized clinical trials to confirm the safety and efficacy of this combination, especially in critically ill patients or patients with cardiovascular dis...
