	Study suggests detailed neuropsychological assessment for brief cardiac arrest survivors Patients who survive a brief cardiac arrest and who appear neurologically intact should nonetheless receive a detailed neuropsychological assessment before being discharged, suggests a joint study by researchers at Baycrest's Rotman Research Institute and Israel's Rambam Medical Center.

	Increasing prevalence of functional mitral regurgitation related to severity of heart failure One potential therapeutic concept for treating heart failure besides guideline directed medical therapy, is to correct any concomitant severe mitral valve insufficiency (mitral regurgitation). Despite numerous treatment options being available, it is still not clear which patients will benefit most from such an intervention.

			Researchers develop comprehensive map of genetic risk factors for stroke Stroke is a serious disease affecting blood flow to and from the brain, and is the second leading cause of death worldwide. Stroke is characterized by a sudden onset of neurological dysfunction, caused by a blood clot or hemorrhage in a cerebral artery. While many genetic variants and lifestyle behaviors have been identified as risk factors for stroke, the genetic basis for the disease is unknown.

			New device achieves 92% accuracy in detecting patients with severe stroke A new device worn like a visor can detect emergent large-vessel occlusion in patients with suspected stroke with 92 percent accuracy, report clinical investigators at the Medical University of South Carolina, Mount Sinai, the University of Tennessee Health Sciences Center and elsewhere in an article published online on March 6, 2018, in the Journal of Neurointerventional Surgery.

			Johns Hopkins researchers make great strides in understanding biology behind pulmonary hypertension Working with cells that line the innermost layer of the blood vessels, Johns Hopkins investigators say they have made a leap forward in understanding the underlying biology behind pulmonary hypertension, a dangerous type of high blood pressure in lungs that ultimately leads to right heart failure and death.

	Screening for Rheumatic Heart Disease Acute rheumatic fever (ARF) is a significant source of morbidity and mortality in developing and underdeveloped regions of the world, but is almost negligible in the developed nations.

	Grilled meat could be raising the risk of hypertension finds study Studies have shown that grilled meat including beef, poultry, fish etc. is usually cooked at high temperatures. This charring can produce cancer causing chemicals. In a new study researchers have found that consuming meat (both white and red) cooked over open flames or at high temperatures can lead to an increased risk of high blood pressure. These results were revealed this week at a meeting of the American Heart Association.

	Researchers uncover specific gene region in hypertension Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a cell determine what that cell can do.

	High-fat, high-cholesterol diet depletes ranks of artery-protecting immune cells New research from scientists at the La Jolla Institute for Allergy and Immunology shows how a diet high in fat and cholesterol depletes the ranks of artery-protecting immune cells, turning them into promoters of inflammation, which exacerbate atherosclerotic plaque buildup that occurs in cardiovascular disease.

	Are there risks from secondhand marijuana smoke? Early science says yes. The inspiration arrived in a haze at a Paul McCartney concert a few years ago in San Francisco. “People in front of me started lighting up and then other people started lighting up,” said Matthew Springer, a biologist and professor in the division of cardiology at the University of California-San Francisco. “And for a few naive split seconds I was thinking to myself, ‘Hey, they can’t smoke in AT&T Park! I’m sure that’s not allowed.

	Patients with vascular malformations have poor health-related quality of life Patients with vascular malformations, which include blood vessel, artery and lymph vessel abnormalities, appear to have more pain and mental health distress than the general U.S. population and that can contribute to poor health-related quality of life.

	Depression may be linked to increased risk of atrial fibrillation A study has shown that depression may be a risk factor for atrial fibrillation, a common heart rhythm disorder that can cause clot formation and stroke.

	Researchers measure whether transcranial direct current stimulation generates EFs in deep brain areas A defining characteristic of stroke is the loss of motor control due to structural damage in specific brain areas. In fact, motor impairments (or deficits) are the number one complication after stroke.

	Leading experts to promote cardiovascular health at EuroPrevent 2018 The impact of nutrition and lifestyle on cardiovascular health will be key elements discussed by health professionals during EuroPrevent 2018 in Ljubljana, Slovenia, in April. EuroPrevent is the annual congress of the European Association of Preventive Cardiology, a branch of the European Society of Cardiology.

	What is a Bicuspid Aortic Valve? A bicuspid aortic valve (BAV) is the most common form of congenital heart disease and is present in about 2% of the population, affecting twice as many males as females. It is an abnormal form of the aortic valve between the heart and the aorta, the great vessel which supplies blood to the whole body except the lungs.

	Health Effects of a Gluten Free Diet Gluten is a family of proteins that make up about 85% to 90% of the protein composition found in wheat, barley, rye and some other grains. It is made up of almost equal proportions of two types of proteins called gliadins and glutenins, of which each has many subtypes. Thus, the genetic diversity of gluten is staggering.

	Radiologist creates dramatic teaching tool using power of VR Physicians, trainees and even laypeople can now stand right beside an expert radiologist as he performs one of the most difficult medical procedures of its kind - in virtual reality.

	Study explores use of smartwatch to detect atrial fibrillation A smartwatch coupled with a machine learning algorithm was able to detect irregular heartbeat, or atrial fibrillation, with high accuracy in a small group of patients undergoing treatment to restore normal heart rhythm but with lower accuracy in a larger group of people with a self-reported history of AF.

	Vitamin D deficiency linked to metabolic syndrome in postmenopausal women Results of a study carried out in Brazil showed a strong association between vitamin D deficiency and metabolic syndrome in postmenopausal women.

	Study shows benefits of hair loss drug in improving cognitive function and vascular health Minoxidil, a popular drug used on the scalp to treat hair loss, might improve blood flow to the brain, lower blood pressure and increase elasticity in the blood vessels if taken in an oral form, according to a new study in mice.

	Anticoagulant drugs found safe to use in patients undergoing surgery for irregular heartbeat A trial led by the University of Birmingham has found that two types of blood thinning drugs are safe to use in patients with an irregular heartbeat when they are undergoing surgery aimed at stopping the condition.

	Medicare metrics may not completely reflect hospital quality for readmissions Over the past several years, the Centers for Medicare & Medicaid Services have reported hospital quality measures on the Hospital Compare website, providing the public with a way to compare hospital performance.

	Researchers develop microsensor that enables kidney dialysis to be customized Researchers from Eindhoven University of Technology have developed a microsensor that makes it possible to directly monitor and adjust the composition of kidney dialysis fluid.

	New findings could have revolutionary impact on quality of life of older people Researchers from UNSW and Harvard Medical School have discovered that replacing two naturally occurring molecules in the body could reverse symptoms of aging, potentially influencing how the body responds to and performs exercise.

	Restoring enzyme may help reverse effects of vascular aging, study shows As people age, their blood-vessel density and blood flow decrease, which is why it's harder to maintain muscle mass after 40 and endurance in the later decades, even with exercise.

	New study identifies key cellular mechanisms behind vascular aging in mice We are as old as our arteries, the adage goes, so could reversing the aging of blood vessels hold the key to restoring youthful vitality? The answer appears to be yes, at least in mice, according to a new study led by investigators at Harvard Medical School.

	Experts highlight urgent need to prevent infections in patients undergoing hemodialysis Patients with kidney failure who are treated with hemodialysis are at substantially increased risk of life-threatening infections.
