People who sleep fewer than 7 hours per night have lower levels of gene-regulating molecules, or microRNAs, which help dampen down inflammation in cells and support vascular health.
Some patients with atrial fibrillation or A-Fib need an ablation, which requires a catheter and an advanced 3D map of the heart. Researchers have developed the first algorithm that guides catheter movements and accurately detects A-Fib targets without 3D maps of the heart. In human simulations, this technique stops the catheter at the right target and identifies the source type with a 95.25% success rate and a 99 percent detection rate of scar tissue, regardless of scar size.
A team of Lehigh University researchers is working to characterize the mysterious protein known as the Von Willebrand Factor (vWF). In a recent paper published in Biophysical Journal, they advance experimental data for the shear-induced extensional response of vWF, using a microfluidic device and fluorescence microscopy.
Brazilian researchers arrived at this conclusion after conducting cardiovascular fitness tests with boys and girls aged 10-17. The results were published in Cardiology in the Young.
A new study from the University of Eastern Finland shows that a moderately high intake of dietary cholesterol or consumption of up to one egg per day is not associated with an elevated risk of stroke. Furthermore, no association was found in carriers of the APOE4 phenotype, which affects cholesterol metabolism and is remarkably common among the Finnish population.
A newly released expert consensus statement proposes a classification schema for cardiogenic shock that will facilitate communication in both the clinical and research settings. The document was published online in SCAI's Catheterization and Cardiovascular Interventions journal, and is endorsed by the American College of Cardiology, American Heart Association, the Society of Critical Care Medicine and the Society of Thoracic Surgeons.
Study identifies new stem cell type that can significantly improve cardiac function.
Researchers at the National, Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, have developed a novel technique that prevents the obstruction of blood flow, a common fatal complication of transcatheter mitral valve replacement (TMVR). The new method, called LAMPOON, may increase treatment options for high-risk patients previously ineligible for heart valve procedures.
To translate advances in scientific knowledge and innovations in stroke care into improvements in patient outcomes, comprehensive stroke systems of care must be in place to facilitate optimal stroke care delivery. New recommendations support policies that standardize the delivery of stroke care, lower barriers to emergency care for stroke, ensure stroke patients receive care at appropriate hospitals in a timely manner and improve access to secondary prevention and rehabilitation and recovery resources after stroke.
A newly released expert consensus statement provides recommendations for optimizing the financial operations of the cardiovascular catheterization laboratory (CCL) while providing cutting-edge patient care. It is intended for any physician, administrator, or CCL staff member who desires a fundamental understanding of finances and economics of CCLs in the United States. The document, sponsored by SCAI and endorsed by the Alliance of Cardiovascular Professionals (ACVP), was published online in SCAI's official journal, Catheterization and Cardiovascular Interventions.
