Left ventricular (LV) systolic function increases with passive heat stress (HS); however, less is known about diastolic function.

Cardiac magnetic resonance imaging was used to measure biventricular volumes, function, filling velocities, volumetric flow rates, and LV twist and strain at BL and after 45 min of HS. Passive heating reduced left atrial volume (−17.6 ± 11.7 ml, P < 0.05), right and LV end-diastolic volumes (−22.7 ± 11.0 and −25.7 ± 24.9 ml, respectively; P < 0.05), and

A progressive and sustained decrease in systolic blood pressure on the continuation of exercise suggests severe left ventricular dysfunction irrespective of the cause. A transient decrease in systolic blood pressure followed by a normal increase in the continuation of exercise does not have any clinical significance. Failure of systolic blood pressure to increase commensurate to an increase in workload suggests the failure of adequate increase in left ventricular stroke volume with increasing workload. At present there is no consensus about the definition and significance of the exaggerated in

Abstract Measurement of volumetric flow rate (ie, stroke volume or cardiac output) is important for evaluating systolic performance of the heart. Stroke volume is the amount of blood that the heart can eject during systole, specifically during the systolic ejection period from aortic valve opening to aortic valve closure. This ejection phase index depends on the loading conditions of the heart (afterload and preload) and on the intrinsic contractility of the heart muscle. It provides an overall measurement of the ability of the heart to meet the metabolic demands of the body.

Abstract:
Mitral-Septal contact has been proven to be the cause of obstruction in the left ventricle with hypertrophic cardiomyopathy (HC). This paper presents a study on the fluid mechanics of obstruction using two-way loosely coupled fluid-structure interaction (FSI) methodology. A parametric model for the geometry of the diseased left ventricular cavity, myocardium and mitral valve has been developed, using the dimensions extracted from magnetic resonance images. The three-element Windkessel model [1] was modified for HC and solved to introduce pressure boundary condition to the aortic aperture in th

Abstract:
This paper presents a model-based system identification approach to estimation of central aortic blood pressure waveform from non-invasive cuff pressure oscillation signals. First, we developed a mathematical model that can reproduce the relationship between central aortic blood pressure waveform and non-invasive cuff pressure oscillation signals at diametric locations by combining models to represent wave propagation in the artery, arterial pressure-volume relationship, and mechanics of the occlusive cuff. Second, we formulated the problem of estimating central aortic blood pressure waveform

Objective: This study aimed to evaluate the effects of one resistance training (RT) session per week on indicators of blood pressure, glycemic levels, fatigue scores, bone mineral density, and muscle strength. Methodology: A case study was conducted with an elderly patient (78 years old; body mass: 82.8 kg; height (m): 1.54; body mass index: 34.7 kg/m²), breast cancer survivor, with mastectomy, undergoing hormone therapy, diagnosed with type II diabetes, hypertension, and grade I obesity. The RT consisted of one session per week for 8 weeks. The sessions consisted of only four exercises: bench

Abstract:
This article provides data confirming the fact that a physical education lesson, organized according to the principle of circular training, contributes to the intensification of the lesson, which is expressed by an increase in the number of movements and an increase in the energy costs of the body of schoolchildren. They are twice as high as those of schoolchildren in the control group who participate in traditional physical education classes. Experimental studies, which were, carried out from November to May, made it possible to establish that physical education lessons, which were carried ou

Abstract:
Currently, several studies and experiments are being done to create a new generation of ultra-low-power wearable sensors. For instance, our group is currently working towards the development of a high-performance flexible pressure sensor. However, with the creation of new sensors, a need for a standard test method is necessary. Therefore, we opted to create a standardized testbed to evaluate the pressure applied to sensors. A pulse wave is generated when the heart pumps blood causing a change in the volume of the blood vessel. In order to eliminate the need of human subjects when testing press

Abstract:
Introduction: The increasing prevalence of chronic kidney disease (CKD), coupled with advancements in the diagnosis and treatment of renal diseases and improvements in life expectancy, has led to a greater number of patients requiring hemodialysis. The preferred method of vascular access for hemodialysis is AV fistula formation; however, it is associated with a high rate of failure. In our prospective study, we focused on 40 CKD patients planned for initiation of maintenance hemodialysis. Methods: We employed preoperative ultrasound mapping to assess cephalic vein diameter, compressibility, an
