Norwegian University of Science and Technology Norwegian researchers use large database and computer model to understand high blood pressure High blood pressure is highly age-related and affects more than 1 billion people worldwide. But doctors can't fully explain the cause of 90 per cent of all cases. A computer model of a "virtual human" suggests that stiff arteries alone are enough to cause high blood pressure. "Our results suggest that arterial stiffness represents a major...

Researchers from Yale School of Medicine and Celera Diagnostics have confirmed the significance of a genetic variant that substantially increases the risk of a frequently fatal thoracic aortic dissection or full rupture. The study appears online in PLOS ONE. Thoracic aortic aneurysms, or bulges in the artery wall, can develop without pain or other symptoms. If they lead to a tear — dissection — or full rupture, the patient will often die without immediate treatment. Therefore, better...

The most frequently used mechanical circulatory assist device in the world may have untapped potential, physicians say. One of many uses for the intra-aortic balloon pump is helping ensure adequate oxygen and blood delivery to a heart struggling to resume beating in the aftermath of coronary bypass surgery, said Dr. Mary Arthur, cardiovascular anesthesiologist at the Medical College of Georgia and Georgia Regents Health System. However physicians have been advised not to use the balloon...

Trial Evaluates Safety and Efficacy of Nellix Endovascular Aneurysm Sealing System (EVAS) Pittsburgh, PA (PRWEB) March 06, 2014 Allegheny General Hospital (AGH), part of the Allegheny Health Network, has been chosen as the only clinical trial site in Pennsylvania for a new investigational stent graft device designed to be used for the repair of infrarenal aortic aneurysms. The EVAS FORWARD trial, sponsored by Endologix, Inc., will evaluate the safety and efficacy of the Nellix™...

Taking Pulse From The Finger Can Show Aorta Stiffness
2013-09-05 17:09:25

Enid Burns for redOrbit.com – Your Universe Online An academic from the University of Iowa has developed a new, simpler method to measure the stiffness of the aorta, a common risk factor of heart disease. The new method uses an instrument called a transducer on the finger, or over the brachial artery just inside the arm beneath the elbow. Measuring the pulse, combined with factors, including a person's age and body mass index, enables the doctor to determine whether the aorta has...

Fruit Lowers Risk Abdominal Aneurism
2013-08-21 14:54:27

Brett Smith for redOrbit.com - Your Universe Online Fruits can be a refreshing snack on a hot, late-summer afternoon, and a new study from Swedish researchers has found that they can also provide protection against abdominal aneurysms. An aneurysm is a balloon-like bulge in a blood vessel caused by a weakening of the vein or artery wall. Aneurysms commonly occur in the brain, heart and aorta. Aneurysms grow slowly over the course of several years, often without noticeable symptoms....

Families will be able to identify relatives with mutation, take steps to monitor and treat A multi-institutional team led by Dianna Milewicz, M.D., Ph.D., of The University of Texas Health Science Center at Houston (UTHealth) has found a recurrent genetic mutation that has been linked to deadly thoracic aortic dissections in family members as young as 17 years of age. The gene known as PRKG1 makes a protein called cGMP-dependent kinase, type I. The PRKG1 mutation alters the function of...

In a study of more than 2,000 adults, researchers found that two MRI measurements of the abdominal aorta – the amount of plaque in the vessel and the thickness of its wall – are associated with future cardiovascular events, such as a heart attack or stroke. Results of the study are published online in the journal Radiology. "This is an important study, because it demonstrates that atherosclerosis in an artery outside the heart is an independent predictor of adverse...

Researchers at Lund University in Sweden have mapped the significance of heredity for common forms of atherosclerotic disease. No studies have previously examined whether different forms of the disease share heredity. The study looked at coronary heart disease, ischemic stroke, peripheral arterial disease and atherosclerosis of the aorta in individuals whose siblings and parents have suffered different types of cardiovascular disease. The results showed that heredity is highest for...

Aortography
2013-04-30 10:09:04

Aortography is the study of the specific action involving the ejection of blood from the aorta in the heart. Taking an aortogram from the patient could identify if there is a tear in the intimal wall of the aorta. This tear is eventually fatal but can be repaired in some cases. Procedure A catheter is placed in the aorta of the patient, usually through the femoral artery. Once in place a dose of iodine-based dye is injected in order to visualize the flow of blood through the site....
