Numerical predictions of shear stress and cyclic stretch in the healthy pulmonary vasculature [PDF]
arXiv, 2021 Isolated post-capillary pulmonary hypertension (Ipc-PH) occurs due to left heart failure, which contributes to 1 out of every 9 deaths in the United States. In some patients, through unknown mechanisms, Ipc-PH transitions to combined pre-/post-capillary PH (Cpc-PH), diagnosed by an increase in pulmonary vascular resistance and associated with a ...

Deep Metric Learning for the Hemodynamics Inference with Electrocardiogram Signals [PDF]
MLHC 2023, 2023 Heart failure is a debilitating condition that affects millions of people worldwide and has a significant impact on their quality of life and mortality rates. An objective assessment of cardiac pressures remains an important method for the diagnosis and treatment prognostication for patients with heart failure.

Inaccuracy of Wedge Pressure as an Index of Pulmonary Capillary Pressure [PDF]
Circulation, 1958 The wedge and left atrial pressures were compared in 12 subjects with congenital and acquired heart disease; all experiments were carried out with closed chest under basal conditions. A poor correlation between the wedge and left atrial pressures was noted in over half the patients.

Parameter inference in a computational model of hemodynamics in pulmonary hypertension [PDF]
arXiv, 2021 Pulmonary hypertension (PH), defined by a mean pulmonary arterial pressure (mPAP) $>$ 20 mmHg, is characterized by increased pulmonary vascular resistance and decreased pulmonary arterial compliance. There are few measurable biomarkers of PH progression, but a conclusive diagnosis of the disease requires invasive right heart catheterization (RHC ...
arxiv
Europace, 2010 AIMS The aims of this analysis were to assess the agreement between implantable defibrillator (ICD)-measured intrathoracic impedance and pulmonary capillary wedge pressure (PCWP) collected during long-term follow-up, as well as to evaluate whether PCWP ...

Noninvasive Estimation of Mean Pulmonary Artery Pressure Using MRI, Computer Models, and Machine Learning [PDF]
arXiv, 2023 Pulmonary Hypertension (PH) is a severe disease characterized by an elevated pulmonary artery pressure. The gold standard for PH diagnosis is measurement of mean Pulmonary Artery Pressure (mPAP) during an invasive Right Heart Catheterization. In this paper, we investigate noninvasive approach to PH detection utilizing Magnetic Resonance Imaging ...

Pulmonary Circulation, 2023 Pulmonary hypertension secondary to left‐sided valvular disease (VHD‐PH) is associated with high morbidity and mortality. Angiotensin‐receptor neprilysin inhibitor (ARNI) is a novel pharmacotherapy, which reduces afterload with natriuresis and peripheral

Perioperative optimization of Crohn's disease
Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 10-26, January 2023., 2023 Most Crohn's disease patients require surgery during the course of their illness, especially those who experience complications. The management of perioperative medications and surgery‐related decision‐making should be individualized and patient‐centered based on a multidisciplinary approach.
