The reason of sudden death is called


Researchers from the University of California in Berkeley have studied the mechanism of a hypertrophic cardiomyopathy which is the reason of sudden cardiac arrest during physical activities. It is reported in the press release on MedicalXpress. At a hypertrophic cardiomyopathy which is a genetic disease and strikes about one of 500 people there is a thickening of walls of the left and right ventricle. This state is considered a frequent cause of death of young athletes who had no visible symptoms. Patients of advanced age die of stagnant heart failure. During the research scientists used the three-dimensional cultures of cells of human heart. All cages had a mutation in a gene which codes the protein C connecting a myosin. This genetic defect is often observed at patients with a cardiomyopathy. Experts have applied laser 3D - the press to creation of the mobile microscopic supporting structure ("woods"). The miotsita connected with each other could be reduced, squeezing "woods", as in the real heart. Biologists have noticed that cages with anomalies in the conditions of a stress couldn't be reduced correctly therefore the rhythm was broken. Similar occurs at patients when the physical activity raises load of heart, and there is arrhythmia. Normal cages managed to adapt to a stress quickly. According to scientists, creation of more exact models of heart fabric will help to develop more effective methods of treatment of a hypertrophic cardiomyopathy.
