Diastolic dysfunction types in the prediction of viable myocardium functional recovery [PDF]

Vojnosanitetski Pregled, 2008
Background/Aim. It is well known that patients with coronary artery disease and viable tissue as a guarantee of contractile recovery (CR), despite of decreasing ejection fraction (EF) and systolic dysfunction, could have benefit from surgical ...

A Pilot Study Evaluating LV Diastolic Function with M-Mode Measurement of Mitral Valve Movement in the Parasternal Long Axis View

Diagnostics, 2023
This pilot study aimed to develop a new, reliable, and easy-to-use method for the evaluation of diastolic function through the M-mode measurement of mitral valve (MV) movement in the parasternal long axis (PSLA), similar to E-point septal separation ...

Quasi-static imaged-based immersed boundary-finite element model of human left ventricle in diastole [PDF]

, 2014
SUMMARY: Finite stress and strain analyses of the heart provide insight into the biomechanics of myocardial function and dysfunction. Herein, we describe progress toward dynamic patient-specific models of the left ventricle using an immersed boundary ...

Continuous PPG-Based Blood Pressure Monitoring Using Multi-Linear Regression [PDF]

, 2020
In this work, we present the Senbiosys blood pressure monitoring algorithm (SB-BPM) that solely requires a photoplethysmography (PPG) signal. The technology is based on pulse wave analysis (PWA) of PPG signals retrieved from different body locations to continuously estimate the systolic blood pressure (SBP) and the diastolic blood pressure (DBP).

Stability and energy budget of pressure-driven collapsible channel flows [PDF]

, 2011
Although self-excited oscillations in collapsible channel flows have been extensively studied, our understanding of their origins and mechanisms is still far from complete.

Accelerometric Method for Cuffless Continuous Blood Pressure Measurement [PDF]

Noninvasive Accelerometric Approach for Cuffless Continuous Blood Pressure Measurement, IEEE Transactions on Instrumentation and Measurement, vol. 70, pp. 1-9, 2021, Art no. 4008109, 2020
Pulse transit time (PTT) has been widely used for cuffless blood pressure (BP) measurement. But, it requires more than one cardiovascular signals involving more than one sensing device. In this paper, we propose a method for continuous cuffless blood pressure measurement with the help of left ventricular ejection time (LVET).

The Deconvolution of Diastole

Journal of the American College of Cardiology, 2009
Heart failure with normal ejection fraction (HFNEF) is a common presentation in elderly persons and seems to have a prognosis almost as bleak as systolic heart failure. Much work on the pathophysiology of this entity has focused on left ventricular (LV) stiffness ([1][1])—indeed, stiffening ...

Estimating prognosis in patients with acute myocardial infarction using personalized computational heart models [PDF]

, 2017
Biomechanical computational models have potential prognostic utility in patients after an acute ST-segment–elevation myocardial infarction (STEMI). In a proof-of-concept study, we defined two groups (1) an acute STEMI group (n = 6, 83% male, age 54 ± 12 ...

A rare homozygous missense GDF2 (BMP9) mutation causing PAH in siblings: Does BMP10 status contribute?

American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 228-233, January 2023., 2023
Abstract Pulmonary arterial hypertension (PAH) is a disease characterized by pathological remodeling of the pulmonary vasculature causing elevated pulmonary artery pressures and ultimately, right ventricular failure from chronic pressure overload. Heterozygous pathogenic GDF2 (encoding bone morphogenetic protein 9 (BMP9)) variants account for some (>1%)

Aortic valve stenosis: Prognosis and therapy [PDF]

Vojnosanitetski Pregled, 2003
There is a long latent period in the clinical course of aortic valve stenosis in adults. Symptoms usually occur in the case of critical stenosis, when aortic orifice area is under 0.7cm2 (0.4 cm2/m2).
