A new study reveals that cardiometabolic risk factors and subclinical atherosclerosis impair the function of the microvessels that irrigate the heart, potentially increasing atherosclerosis risk.
For coronary artery bypass grafting (CABG), a ‘no-touch’ technique to harvest the saphenous vein graft has been considered superior to the conventional approach. Surprisingly, a new study comes to a different conclusion.
Using a melt electrowriting (MEW) technique, bioengineers have developed a hybrid structure to address the clinical need for small-diameter vascular grafts and help combat cardiovascular disease.
Using vascular organoids derived from stem cells, researchers gain new insights into how diabetes damages blood vessels. This could lead to to the development of new treatments.
Why do aortic aneurysms form where they typically do, at the upper arch or in the abdominal cavity? A new study explores the predilection of these sites for vascular dilatations.
6 out of 10 people develop pain after a limb amputation. Researchers now investigate whether a preventive, relatively simple nerve surgery can prevent patients from experiencing this pain.
Microbubbles in a contrast agent allows for ultrasound imaging of the finest vascular details. This is the working principle of a technique called ultrasound localization microscopy (ULM).
Researchers were able to produce sub-millimetre resolution images of cardiac micro-vessels. This non-invasive new technique could allow scientists to study the physiology of the heart in more detail.
The stiffer the arteries, the greater the cardiovascular risk, according to a new study. The researchers suggest using this as a predictive tool, and emphasise the utility of a specific clinical tool.
Using light instead of x-rays, a new imaging method from Philips is designed to advance navigation through a patient's blood vessels during minimally-ivasive procedures.
Using small blood vessels grown in the lab, researchers discover how vascular leaks leading to dementia and stroke emerge – and how this damage might be fixed.
Cardiologists in Zurich demonstrate that immediate revascularization of non-involved blood vessels offers better outcomes for patients after a heart attack than a delayed procedure.
Patients with heart disease could benefit from less extensive interventions thanks to technology that creates 3D computer models of blood flow through the heart's arteries, according to new research.
One robot supports the surgeon’s control of tiny instruments, while another automatically keeps an eye on what is happening: With this novel combination, surgeons in Münster have successfully performed fully robot-assisted microsurgery for the first time. Presenting the new procedure at the Hornheide Specialist Clinic, the experts explain how the interaction of both robotic systems ensures…
A research group has revealed that SARS-CoV-2 disrupts the vascular endothelial barrier by suppressing the expression of Claudin-5 (CLDN5) to invade the blood vessels.
New research shows that cell-cell signaling could play a key role in the thickening of arteries due to high blood pressure.
Similar to the way exercise helps muscles adapt to workouts, short, repeated bouts of reduced circulation with a blood pressure cuff may help prevent the worst outcomes of heart attacks and strokes.
Networks adapt over time and in this way form a kind of memory. German researchers show that the structure of blood vascular network is dynamic and can adapt to external factors.
When every minute counts: A Swiss team is currently developing a diagnostic procedure that can be used to start a tailored therapy for acute stroke in a timely manner.
