 Study suggests detailed neuropsychological assessment for brief cardiac arrest survivorsStudy 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 failureIncreasing 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 strokeResearchers 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 strokeNew 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 hypertensionJohns 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
 
Screening for Rheumatic Heart DiseaseAcute 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
 
Grilled meat could be raising the risk of hypertension finds studyStudies 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
 
Researchers uncover specific gene region in hypertensionGenes 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
 
High-fat, high-cholesterol diet depletes ranks of artery-protecting immune cellsNew 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.
 
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 have poor health-related quality of lifePatients 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
 
Depression may be linked to increased risk of atrial fibrillationA 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
 
Researchers measure whether transcranial direct current stimulation generates EFs in deep brain areasA 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 2018The 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?
 
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
 
Health Effects of a Gluten Free DietGluten 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.
