1. 1. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

   University essay from Linköpings universitet/Avdelningen för medicinsk teknik

   Author : Frida Hermansson; [2023]
   Keywords : Pulmonary Hypertension; pulmonary hypertension; improving; physiological-guided; machine learning; neural networks; NN; artificial neural networks; non-invasive; PH; tricuspid regurgitation; peak tricuspid regurgitation velocity; tricuspid regurgitation velocity; right ventricular systolic pressure; VGG16; Unet; TR-CNN; CNN; pulmonell hypertension; förbättra; fysiologisk-guidning; neurala nätverk; trikuspidal regurgitation; maximal trikuspidal regurgitation; icke-invasivt;

   Abstract : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

3. 2. Comparison of direct Fick's principle and thermodilution for calculating cardiac output in patients with pulmonary arterial hypertension.Does the assessment of cardiac index and pulmonary vascular resistance differ depending on which method is chosen?

   University essay from Örebro universitet/Institutionen för hälsovetenskaper

   Author : Gabriella Persson; [2023]
   Keywords : Pulmonary arterial hypertension; cardiac output; direct Fick´s principle; thermodilution;

   Abstract : Pulmonary arterial hypertension (PAH) is an uncommon but serious disease that causes increased pressure in the pulmonary vessels and increased pulmonary vascular resistance (PVR), which in turn leads to right heart failure. At diagnosis, mean pulmonary artery pressure (mPAP) must be >20 mmHg, pulmonary artery wedge pressure (PAWP) ≤15 mmHg and PVR >2 Wood units (WU). READ MORE

4. 3. Inflammatory Cell Infiltration and Expression of AT1 and AT2 Receptors in Angiotensin II and High-Salt Diet-Induced Balb/CJ Mice

   University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

   Author : Avishka Herat; [2023]
   Keywords : ;

   Abstract : Pulmonary oedema and pulmonary hypertension are often associated with heart failure. The Balb/CJ and C57BL/6J mouse strains have been shown to exhibit distinct genetic susceptibilities to heart failure. READ MORE

5. 4. Testing of micro-fluidic systems for Raman spectroscopic measurements on biological cells

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Malin Berger; [2018]
   Keywords : ;

   Abstract : Pulmonary Artery Hypertension (PAH) is a condition that can affect people as a consequence of infections or diseases such as lung disease, high blood pressure or pneumonia. When afflicted by these diseases, low oxygen content in the lung tissue causes the pulmonary arterial soft muscle cells (PASMC) located in the walls of the pulmonary arteries to chronically swell up.

6. 5. Novel biomarkers in Pulmonary Hypertension : The correlation between ADMA, SDMA, L-arginine and disease progression and kidney function

   University essay from Umeå universitet/Farmakologi

   Author : Carina Wedegren; [2017]
   Keywords : pulmonary arterial hypertension; ADMA; SDMA; L-arginine; s-creatinine; eGFR;

   Abstract : .... READ MORE
