Patients more likely to develop ischemic stroke after total hip replacement surgeries

An international study involving the University of Southampton has shown people who undergo a total hip replacement are at a higher risk of a stroke in the first two weeks after surgery.

Better understanding of clotting dynamics in atherosclerosis could lead to more effective drugs

The disease atherosclerosis involves the build up of fatty tissue within arterial walls, creating unstable structures known as plaques. These plaques grow until they burst, rupturing the wall and causing the formation of a blood clot within the artery. These clots also grow until they block blood flow; in the case of the coronary artery, this can cause a heart attack.

Calcium intake does not increase risk of coronary artery calcification

Researchers at the Institute for Aging Research (IFAR) at Hebrew SeniorLife, an affiliate of Harvard Medical School (HMS), have published a study that shows no evidence of a link between calcium intake and coronary artery calcification, reassuring adults who take calcium supplements for bone health that the supplements do not appear to result in the development of calcification of blood vessels.

WU researchers to study blood-clotting disorders

Researchers at Washington University School of Medicine in St. Louis have received a $9 million grant to investigate blood-clotting disorders. From heart attacks and strokes to uncontrolled bleeding, clotting disorders cause more deaths each year in the United States than all types of cancer combined.

Excessive turnover of placental cells may trigger unnatural increase in blood pressure

Excessive turnover of cells in the placenta may trigger an unnatural increase in blood pressure that puts mother and baby at risk, researchers say.

Link between SFRP4 protein and risk of type 2 diabetes

When a patient is diagnosed with type 2 diabetes, the disease has usually already progressed over several years and damage to areas such as blood vessels and eyes has already taken place. To find a test that indicates who is at risk at an early stage would be valuable, as it would enable preventive treatment to be put in place.

Turning off GSK-3α protein activity can prevent heart remodeling

When a person has a heart attack, portions of the heart muscle die in the next several days or even weeks if deprived of oxygen for long enough. The recovering heart slowly remodels itself, even fostering the growth of new blood vessels, in an attempt to regain some of its former function. But all too often, the remodeling is actually harmful, and the damaged heart is on an inevitable downward slide to heart failure.

Geldanamycin degrades VEGFR2 protein that triggers blood vessel growth

The drug, geldanamycin, is well known for attacking a protein associated with the spread of breast cancer. However, a laboratory-based study found it also degraded a different protein that triggers blood vessel growth.

Brain bleeds in premature babies: an interview with Edward Ahn

Premature babies are born during their third trimester and they are vulnerable to having brain bleeds because their brains are not completely developed. There are some fragile blood vessels that are present in every developing infant, but when the babies are born early, these blood vessels can be subject to changes in blood pressure and changes in breathing patterns and, due to their fragility, they can develop a hemorrhage.

Adenovirus detection not uncommon among children with Kawasaki disease

Clinicians should take caution when diagnosing a child who has a high fever and whose tests show evidence of adenovirus, and not assume the virus is responsible for Kawasaki-like symptoms. According to a new study from Nationwide Children's Hospital appearing in Clinical Infectious Diseases, adenovirus detection is not uncommon among children with Kawasaki disease.

Larger aneurysms linked to greater fluctuations in flow behaviour

Brain aneurysms occur in about six percent of the population. They are dilated sections of blood vessels, which can deteriorate over time until the blood vessel wall ruptures, resulting in a haemorrhage. This causes a loss of mental functions and severe headaches. Haemorrhages of this kind can even be life threatening. The treatment of such patients involves complex medical decision-making. The models developed by Julia Mikhal can be of great use in this regard.

Study compares effectiveness of CABG surgery with PCI for adults with diabetes and heart disease

Adults with diabetes and multi-vessel coronary heart disease who underwent cardiac bypass surgery had better overall heart-related outcomes than those who underwent an artery-opening procedure to improve blood flow to the heart muscle, according to the results from an international study. The research was supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.

Adding angiogenesis inhibitor to anti-HER2 drugs extends survival in mice with breast cancer

Adding an angiogenesis inhibitor to treatment with a HER2-inhibiting drug could improve outcomes for patients with HER2-positive breast cancer who develop brain metastases. In their report published online in PNAS Plus, Massachusetts General Hospital (MGH) investigators report the first preclinical study combining antiangiogenic and anti-HER2 drugs in an animal model of brain metastatic breast cancer.

Bypass surgery offers people with diabetes better long-term survival than stents

People with diabetes mellitus who undergo heart bypass surgery for multiple blocked arteries have a significantly better 5-year-survival rate than diabetic patients who undergo angioplasty with drug-eluting stents (DES), according to a study published in the November 2012 issue of The Annals of Thoracic Surgery.

Near-complete blood flow restoration necessary to preserve neurological function following stroke

Two Rhode Island Hospital researchers recently found that restoring near-complete blood flow to the brain is necessary to restore or preserve neurological function following stroke. Seems like a no-brainer, right? Yet until their research was complete, many physicians and researchers believed that partial blood-flow restoration was good enough. Not anymore.

Repeated surgeries may improve survival for patients with glioblastomas

People who undergo repeated surgeries to remove glioblastomas - the most aggressive and deadliest type of brain tumors - may survive longer than those who have just a one-time operation, new Johns Hopkins research suggests.

Study finds link between severe sepsis and chronic diseases

It's a major cause of death, yet few of us have ever heard of it. Sepsis occurs when a patient's immune system overreacts to an infection, triggering a potentially fatal, system-wide inflammation. Severe sepsis strikes about 750,000 Americans each year, most of them older and often ill, with as many as half of these patients dying as septic shock shuts down their organs. Furthermore, patients in many Southern states are about twice as likely to develop sepsis for reasons unknown.

Ischemic stroke: an interview with Dr Gregory Ford

A stroke is a sudden interruption of blood flow to the brain which deprives the brain of oxygen and nutrients. Approximately two millions brain cells die each minute during a stroke. This can lead to brain damage, physical and mental disability and death.

Study finds that just 1 high-fat meal can affect your heart health

Eat a breakfast sandwich and your body will be feeling the ill effects well before lunch - now that's fast food!

Mediterranean meal may have positive effects on arteries

A single junk food meal - composed mainly of saturated fat - is detrimental to the health of the arteries, while no damage occurs after consuming a Mediterranean meal rich in good fats such as mono-and polyunsaturated fatty acids, according to researchers at the University of Montreal-affiliated éPIC Center of the Montreal Heart Institute.
