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.

CTA scans with reduced amount of contrast medium and radiation dose still provide good image quality

Wouter Nijhof obtained his PhD at the University of Twente for the research he conducted in collaboration with the Radiology department at the Jeroen Bosch Hospital in 's-Hertogenbosch.

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.

New approach helps create virtual models for treating abdominal aortic aneurysms

Virtual models can be created in the angiography room thanks to an approach developed by researchers at the University of Montreal Hospital Research Centre and the university's departments of radiology, radiation oncology, and nuclear medicine. The latest advances were presented by Dr. Gilles Soulez at the Cardiovascular and Interventional Radiology Society of Europe conference on September 27, 2015.

Use of chest CT scans for hospital emergency-room patients with blunt trauma can be reduced: Study

Use of computed tomography (CT) scans of the chest for hospital emergency-room patients with blunt trauma could be reduced by more than one-third without compromising detection of major injury, concludes a new study led by a UC San Francisco physician.

Anti-coagulant medications quickly resolve blood clots that could impair valve motion

Heart valve replacements made from tissue (bioprosthetic valves) have long been thought to be spared the complication of blood clot formation. Researchers have now found that about 15 percent of all bioprosthetic aortic heart valve patients develop blood clots on the leaflets affecting valve opening, regardless of whether the patient received the new valve via open-heart surgery or a minimally-invasive catheter procedure, a new study from the Cedars-Sinai Heart Institute shows.

Novel radiopharmaceutical probe has potential to save lives of patients with ischemic stroke

A novel radiopharmaceutical probe developed at Massachusetts General Hospital has the potential of providing physicians with information that could save the lives of patients with ischemic stroke or pulmonary embolism - conditions caused when important blood vessels are blocked by a clot that has traveled from another part of the body.

LCZ696 reduces aortic systolic blood pressure, pulse pressure in hypertensive patients

The combination drug valsartan/sacubitril known as LCZ696 significantly reduced aortic systolic blood pressure and pulse pressure compared to the standard angiotensin receptor blocker (ARB) olmesartan in patients with hypertension, according to results of the PARAMETER study.

Computational fluid dynamics modeling confirms better blood flow with new stent graft design

Vascular surgeon Pat Kelly of Sanford Health in Sioux Falls, South Dakota, knew his patients were doing better with the stent graft he designed, but he wanted a better understanding of the mechanics before testing the device more widely in a clinical trial. For that, he reached out to South Dakota State University.

Loyola University Medical Center first in Illinois to offer new, noninvasive test for heart disease

Loyola University Medical Center is the first and only hospital in Illinois to offer a new, noninvasive technology to test for coronary artery disease.

Arterial shunt in hybrid palliation better for hypoplastic left heart syndrome treatment

Children born with the major congenital heart defect hypoplastic left heart syndrome (HLHS) often must undergo a series of corrective surgeries beginning at birth. While most have the standard three-stage Norwood procedure, a hybrid strategy has been introduced to offset some disadvantages associated with the Norwood surgeries. In a report in The Journal of Thoracic and Cardiovascular Surgery, investigators compare whether outcomes can be improved if an arterial shunt is used as a source of pulmonary blood flow rather than the more conventional venous shunt as part of the hybrid strategy of HLHS surgical reconstruction.

Less invasive endovascular aortic repair benefits most patients, provides quick recovery

Each year, nearly 40,000 Americans undergo elective surgery to repair an abdominal aortic aneurysm with the goal of preventing a life-threatening rupture of this potentially dangerous cardiovascular condition.

Yale researchers provide genetically personalized care for patients with thoracic aortic aneurysms

Researchers at the Aortic Institute at Yale have tested the genomes of more than 100 patients with thoracic aortic aneurysms, a potentially lethal condition, and provided genetically personalized care. Their work will also lead to the development of a "dictionary" of genes specific to the disease, according to researchers.

Women who take stop-smoking drug Zyban during pregnancy give birth to a child with birth defects

The Arentz Law Group is currently investigating cases of birth defects caused by the stop-smoking drug Zyban. Women who have taken Zyban while pregnant, and given birth to a child born with a birth defect, are encouraged to contact the law firm immediately for a free legal consultation.

Study reveals benefit of early screening for vascular disorder patent ductus arteriosus among preterm infants

Among extremely preterm infants, early screening for the vascular disorder patent ductus arteriosus before day 3 of life was associated with a lower risk of in-hospital death and pulmonary hemorrhage, but not with differences in other severe complications, according to a study in the June 23/30 issue of JAMA.

Men benefit from ultrasound screening for abdominal aortic aneurysms

Men benefit from one-time screening for abdominal aortic aneurysms via ultrasound. Studies provide proof that their risk of dying is reduced, the abdominal aorta ruptures less often, and emergency surgery can be avoided more often. Far fewer data are available for women and they show no relevant differences between the groups investigated.

Researchers discover genetic mutation responsible for thoracic aortic aneurysm and dissection

Thoracic aortic aneurysm and dissection (TAAD), an enlargement or tearing of the walls of the aorta in the chest, is, together with abdominal aortic aneurysms, responsible for about 2% of all deaths in Western countries. The aorta is the largest artery in the body, and carries blood from the heart. About one out of every five patients with TAAD has a family member with the same disorder, therefore indicating a genetic cause.

Blood research could improve treatment for injured soldiers on the battlefield

Blood research conducted by biomedical engineers from The University of Texas at San Antonio College of Engineering, in collaboration with the Blood Research Program of the U.S. Army Institute of Surgical Research, could change the way injured soldiers are treated on the battlefield.
