New software that simulates interventions could spare young heart patients from surgery

Children with congenital heart defects often undergo a battery of strenuous examinations and interventions. In the EU CARDIOPROOF project, Fraunhofer researchers have developed software to simulate certain interventions in advance.

Serious heart problem can run in families and occur at similar ages, study suggests

People with a family member who had an aortic dissection—a spontaneous tear in one of the body's main arteries—should take note of the age that family member was when the aortic dissection occurred.

Diabetes medication offers protection against arterial stiffness in overweight female mice

Obesity and Type 2 diabetes are associated with vascular stiffening and the development of cardiovascular disease.

Radial access gains ground over femoral route for PCI

A meta-analysis supports that radial access delivers better outcomes and improved safety than femoral access in patients undergoing percutaneous coronary intervention.

ART alone not sufficient to reduce arterial inflammation among HIV-infected patients, study finds

Initiating antiretroviral therapy (ART) soon after diagnosis of an HIV infection did not prevent the progression of significant arterial inflammation in a small group of previously untreated patients.

Arterial switch to 12 o'clock position linked to myocardial ischaemia risk in adolescence

Arterial switch to the 12 o'clock position is associated with abnormal coronary perfusion in adolescence, reveals research presented today at EuroCMR 2016.1 Babies born with transposition of the great arteries (TGA) undergo the arterial switch operation in the first days of life.

Study shows women undergoing TAVR have longer-term survival rate compared to men

Data from one of the largest national registries of transcatheter aortic valve replacement (TAVR) patients shows that although women are more likely to experience vascular complications in the hospital, their one-year survival rate is more favorable than men.

New AVERT system can reduce radiographic dye volume in patients at risk of AKI

In the largest study of its kind, a new device has been found to significantly reduce the volume of radiographic dye without decreasing image quality in patients who are at risk of developing acute kidney injury (AKI) after undergoing a coronary angiography or percutaneous coronary intervention (PCI).

Stereotactic body radiation therapy for NSCLC patients may raise non-cancer mortality risk

Researchers have found that treating patients who have early stage non-small cell lung cancer (NSCLC) with a type of radiotherapy called stereotactic body radiation therapy (SBRT) is associated with a small but increased risk of death from causes other than cancer.

Exercise may promote cardiovascular health in chronically stressed individuals

Constant stress is associated with signs of poor blood vessel health and increased risk of cardiovascular disease. New research presented today at the Experimental Biology 2016 meeting in San Diego finds that aerobic exercise kept the blood vessels of stressed rats working normally.

Study: Age and gender affects prevalence of certain peripheral vascular diseases

New findings from large-scale studies of more than 3.6 million people who underwent screening for cardiovascular disease reveals that a person's age and gender affects the prevalence of certain types of peripheral vascular diseases (PVD), and that diabetes is a major risk factor for developing these diseases, even in patients without heart disease.

White coat hypertension, masked hypertension increase cardiovascular events over the years

Patients whose blood pressures spikes in the doctor's office but not at home, and patients whose blood pressure spikes at home but not in the doctor's office, suffer more heart attacks, heart failure, and strokes than patients with normal blood pressures in both settings, UT Southwestern Medical Center researchers have found.

Notch activation determines signals necessary to generate hematopoietic stem cells in laboratory

An international study led by researchers from IMIM (Hospital del Mar Medical Research Institute) published in the journal Nature Communications has revealed that the intensity or efficiency of the activation of a protein called Notch, which is involved in the different phases of embryonic development, determines the fate of cells, i.e. if cells will form the aorta artery or blood (hematopoietic) stem cells. For artery cells, many Notch molecules need to be activated, whereas for hematopoietic cells many fewer are needed.
