Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

Normal range of blood pressure in 7-11 year old children in Zahedan

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2003
Background and Objective: Normal blood pressure varies based on age, sex, height and weight, however it is necessary to use standard references of evaluate the values. The objective of this study was to determine the rate of normal blood pressure in 7-11

Initial Phase of Ventricular Systole: Asynchronous Contraction

, 1955
The initial phase of ventricular systole has been termed the phase of isometric contraction because all the cardiac valves are closed while the pressure is rapidly elevated.

Performance of Free‐Running Cardiac and Respiratory Motion‐Resolved Whole‐Heart 5D MRI in Congenital Heart Disease Patients Using a Gadolinium Enhanced Fast‐Interrupted Steady‐State Sequence

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.

Myocardial Perfusion Defects in Hypertrophic Cardiomyopathy Mutation Carriers

Journal of the American Heart Association, EarlyView., 2021
Background Impaired myocardial blood flow (MBF) in the absence of epicardial coronary disease is a feature of hypertrophic cardiomyopathy (HCM). Although most evident in hypertrophied or scarred segments, reduced MBF can occur in apparently normal segments.

The effect of cardiac phase on distractor suppression and motor inhibition in a stop-signal task

Scientific Reports
Past work has shown that stimuli timed to the cardiac systole, the time at which heartbeat feedback is transmitted to the brain, can be more effectively selected from conflicting information.

Impact on variation in the direction of cuff bladder on blood pressure readings

Journal of the Practice of Cardiovascular Sciences, 2019
Introduction: Elevated blood pressure (BP)/hypertension contributes significantly to global morbidity and mortality. It is a silent killer; therefore, earlier diagnosis is imperative. A simple instrument called sphygmomanometer measures BP.

Ultrasound-based haemodynamic force trajectories in a murine model of reversible pressure overload. [PDF]

J Physiol
Abstract figure legend High‐resolution ultrasound anatomical imaging and speckle‐tracking analysis were used to compute left ventricular (LV) haemodynamic forces (HDF) in a murine model of transverse aortic constriction (TAC) followed by aortic debanding (deTAC).

Metaphors in Systolic Geometry [PDF]

Proceedings of the International Congress of Mathematicians 2010 (ICM 2010), 2011
This is an expository essay about systolic geometry. It describes a central theorem in the subject and why the proof is difficult. Then it discusses different metaphors which suggest ways to approach the problem. The metaphors connect the systolic inequality to minimal surfaces, topological dimension, scalar curvature, and hyperbolic geometry.
