When young athletes experiences sudden cardiac death as they run down the playing field, it's usually due to arrhythmogenic cardiomyopathy (ACM), an inherited heart disease. Now, researchers have shed new light on the role of the immune system in the progression of ACM and, in the process, discovered a new drug that might help prevent ACM disease symptoms and progression to heart failure in some patients.
Read moreResearch has shown that while elite athletes overall are at decreased risk of death from cardiovascular problems, a certain group of athletes — football linemen in the United States — actually have higher risk than the general population than other elite athletes.
Read moreDrinking small amounts of alcohol frequently is linked with a higher likelihood of atrial fibrillation than binge drinking, according to new research.
Read morePulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can cause the heart to weaken or fail.
Read moreMutations in the gene that encodes a protein called ANT cause a variety of conditions, such as heart disease, but the underlying mechanism of how these mutations trigger disease has been unclear. Researchers discovered that ANT is critical for a quality control process called mitophagy — which helps to ensure the integrity of the mitochondria network — and found that mutations that lead to a defective quality control system cause heart disease.
Read moreInsulin is normally produced by pancreatic beta cells. In many people with diabetes, pancreatic cells are not functional, causing a chronic and potentially fatal insulin deficiency that can only be controlled through daily insulin injections. However, this approach has serious adverse effects. In order to improve therapy, researchers have identified a protein called S100A9 which seems to act as a blood sugar and lipid regulator while avoiding the most harmful side effects of insulin.
Read moreIn symptom-free individuals, the detection of misfolded amyloid-beta protein in the blood indicated a considerably higher risk of Alzheimer's disease — up to 14 years before a clinical diagnosis was made. Amyloid-beta folding proved to be superior to other risk markers evaluated.
Read moreWhen the adrenal gland produces too much aldosterone, this often leads to high blood pressure and kidney damage (hyperaldosteronism). It has only recently emerged that several patients harbor a mutation in the gene for the ClC-2 chloride channel. Researchers have now been able to show for the first time how the altered channels cause the disease.
