The renin-angiotensin system in healthy human platelets: expressed but inactive

Platelets
Platelets play a crucial role in arterial thrombus formation, offering potential for new antiplatelet therapies with reduced bleeding risk. Here, we investigated the role of the renin-angiotensin system (RAS) in human platelets and explored its potential

The normal ranges of cardiovascular parameters measured using the ultrasonic cardiac output monitor [PDF]

, 2017
The ultrasonic cardiac output monitor (USCOM) is a noninvasive transcutaneous continuous wave Doppler method for assessing hemodynamics. There are no published reference ranges for normal values in adults (aged 18– 60 years) for this device.

A Novel Application of Radiomics Analysis for the Evaluation of Centroid Radii Model Texture on the Surface of Cerebral Aneurysms

Stroke: Vascular and Interventional Neurology
BACKGROUND The centroid radii model (CRM)—defined as the distance from aneurysm surface points to the centroid—has shown promise in distinguishing ruptured from unruptured intracranial aneurysms by capturing morphological characteristics.

Estimated pretreatment hemodynamic prognostic factors of aneurysm recurrence after endovascular embolization. [PDF]

, 2017
BACKGROUND:Hemodynamic factors play important roles in aneurysm recurrence after endovascular treatment. OBJECTIVE:Predicting the risk of recurrence by hemodynamic analysis using an untreated aneurysm model is important because such prediction is ...

Dobutamine stress MRI in pulmonary hypertension: relationships between stress pulmonary artery relative area change, RV performance, and 10-year survival [PDF]

, 2017
In pulmonary hypertension (PH), right ventricular (RV) performance determines survival. Pulmonary artery (PA) stiffening is an important biomechanical event in PH and also predicts survival based on the PA relative area change (RAC) measured at rest ...

Computational simulations demonstrate altered wall shear stress in aortic coarctation patients previously treated by resection with end-to-end anastomosis [PDF]

, 2011
Background.  Atherosclerotic plaque in the descending thoracic aorta (dAo) is related to altered wall shear stress (WSS) for normal patients. Resection with end-to-end anastomosis (RWEA) is the gold standard for coarctation of the aorta (CoA) repair, but

Echocardiography combined with cardiopulmonary exercise testing for the prediction of outcome in idiopathic pulmonary arterial hypertension [PDF]

, 2016
BACKGROUND: Right ventricular (RV) function is a major determinant of exercise intolerance and outcome in idiopathic pulmonary arterial hypertension (IPAH). The aim of the study was to evaluate the incremental prognostic value of echocardiography of the

Primary Cardiac Epithelioid Angiosarcoma in a Latin American Patient: Case Report and Literature Review

Case Reports in Oncological Medicine, 2019
Cardiac angiosarcoma is a rare and clinically challenging pathology. It is a high-grade primary malignant tumor of the heart tissue that has many variants, of which the epithelioid variant is rarely present in the heart or the great vessels. As with many
