Abdominal aortic aneurysm (AAA) is a ballooning of the aorta, the largest blood vessel in the human body, which extends into the abdomen. If the wall of this blood vessel becomes weakened, it can stretch, "balloon" out and rupture. A rupture, if left untreated, can lead to life-threatening internal bleeding. The exact cause of this condition is unknown. However, it often occurs in older adults, especially males, those with a high cholesterol level, and in smokers. There also tends to be a genetic link to this disorder.
We know that antibiotics treat bacterial infections. We also know why they work. Tetracycline antibiotics, for example, stop bacteria from making protein. Like a boot on a wheel, the drugs bind to the bacterial cell's ribosome--where protein is made--and prevent it from working. Without protein, the bacteria weaken and die.
Ultrasound conducted before a patient develops symptoms could improve early detection of diseases in blood vessels, research led by the University of Leicester has shown.
Researchers centered at the University of Tsukuba and Kansai Medical University in Japan reveal matricellular protein Thrombospondin-1 (Thbs1) contributes to the development of aortic aneurysm in mice and humans.
A new research hub is set to transform Australia’s medical technology sector by developing cost-competitive technologies for the rapid production of medical devices.
During the 12 months after undergoing noncardiac surgery, patients with or at risk for heart disease who were treated with the beta blocker metoprolol for 30 days were less likely than patients who received a placebo to have a heart attack, but more likely to die or have a stroke, according to research presented at the American College of Cardiology's 67th Annual Scientific Session.
Researchers in Hamilton have discovered that a blood-thinning drug, dabigatran, significantly reduces the risk of death, heart attack, stroke, and other heart or blood-vessel complications in patients who have a heart injury following major, non-cardiac surgery.
New research from a Swedish and Danish team of researchers led from Karolinska Institutet lend additional support to a link between treatment with fluoroquinolone antibiotics and an increased risk of acute aortic disease. The study is published in the esteemed journal The BMJ.
The Affordable Care Act's Medicaid expansion was linked to better access to surgery and higher quality surgical care, according to a new study from Harvard T.H. Chan School of Public Health.
Regular physical activity is a common therapy for people with cardiovascular problems, but not recommended to those with Marfan syndrome, a rare disease of the connective tissue, but mainly affecting the cardiovascular system.
Researchers have found a link between dysregulated tryptophan metabolism and abdominal aortic aneurysm, a life-threatening vascular disease, according to a new study led by Georgia State University.
In an analysis of published studies, lower levels of alcohol consumption were associated with a lower risk of abdominal aortic aneurysm until approximately 15 to 20 g/day, with an increasing risk thereafter. In the British Journal of Surgery analysis, the increase in risk beyond 2 units/day was stronger in men than in women.
University Hospitals Cleveland Medical Center once again has been recognized as one of the nation's best hospitals for 2017–18 by U.S. News & World Report.
Yale University researchers have developed a way in which medical imaging could potentially be used to assess a patient's rupture risk for abdominal aortic aneurysm.
Elastin and collagen serve as the body's building blocks. They provide tensile strength and elasticity for a number of organs, muscles and tissues. Any genetic mutation short-circuiting their function can have a devastating, and often lethal, health impact.
A new study in the journal Health Affairs shows that, despite being designed to more effectively manage care and control costs, black patients enrolled with Medicare Advantage are far more likely to be readmitted to the hospital after a surgery than those enrolled on traditional Medicare.
Researchers are working to determine why the aortic valve doesn't form correctly in patients with the most common congenital heart defect: bicuspid aortic valve.
Researchers at Umeå University in Sweden have discovered a genetic mutation that can cause dissection of the thoracic aorta, which is the body's main artery.
Mortality rates for women undergoing surgery for abdominal aortic aneurysms are nearly twice those for men, a new study has found.
One of the top ten killers for men older than 55 is the target of Clemson University research that could lead to a new life-saving therapy and a better way of telling whether surgery is necessary.
With the recent opening of the Vanderbilt Marfan Syndrome and Aortic Disorders Center, the state's only comprehensive clinic serving entire families, hundreds of patients with connective tissue disorders now have a one-stop shop for health care.
