Predicting Pulmonary Hypertension by Electrocardiograms Using Machine Learning [PDF]

arXiv, 2023
Pulmonary hypertension (PH) is a condition of high blood pressure that affects the arteries in the lungs and the right side of the heart (Mayo Clinic, 2017). A mean pulmonary artery pressure greater than 25 mmHg is defined as Pulmonary hypertension.

Serum Hepatocyte Growth Factor Concentration Correlates with Albuminuria in Individuals with Optimal Blood Pressure and Untreated Arterial Hypertension

Biomedicines
Background/Objectives: Hepatocyte growth factor (HGF) is a protective factor against acute renal injury and chronic renal fibrosis. A positive correlation between HGF and blood pressure (BP) has been established.

Microvascular alterations in hypertension and vascular aging [PDF]

, 2017
Hypertension and aging are characterized by vascular remodelling and stiffness as well as endothelial dysfunction. Endothelial function declines with age, since aging is associated with senescence of the endothelium due to increased rate of apoptosis and

Arterial Hypertension

, 2022
Hypertension is a complex, multifactorial and multisystem disorder and a leading cause of morbidity and premature death globally. Major guidelines define it as systolic blood pressure > 130 mmHg and/or diastolic blood pressure > 80 mmHg. Hypertension is a very common disease with prevalence rates of about 30% in adults worldwide.

PHT-bot: Deep-Learning based system for automatic risk stratification of COPD patients based upon signs of Pulmonary Hypertension [PDF]

Proc. SPIE 10950, Medical Imaging 2019: Computer-Aided Diagnosis, 109500O, 2019
Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity and mortality worldwide. Identifying those at highest risk of deterioration would allow more effective distribution of preventative and surveillance resources. Secondary pulmonary hypertension is a manifestation of advanced COPD, which can be reliably diagnosed by the main ...

The serotonin transporter promotes a pathological estrogen metabolic pathway in pulmonary hypertension via cytochrome P450 1B1 pulmonary circulation [PDF]

, 2016
Pulmonary arterial hypertension (PAH) is a devastating vasculopathy that predominates in women and has been associated with dysregulated estrogen and serotonin signaling. Overexpression of the serotonin transporter (SERT+) in mice results in an estrogen-
