Sudden cardiac death is a risk for patients with heart failure who are carriers of this variant in the histidine-rich calcium-binding protein as a result of calcium inside heart cells that is not properly controlled, possibly leading to development of arrhythmias.<\/p>\n<p>&#8220;This is an extremely interesting finding and may have significant implications in heart failure treatment,\u201d Kranias explains. &#8220;The identified variant in the histidine rich calcium binding protein may serve as a prognostic factor for arrhythmia development in heart failure patients leading to new front in the field of cardiology.\u201d<\/p>\n<p>The histidine-rich calcium-binding protein (HRC) regulates calcium use in the heart and plays an important role in heart contraction and relaxation. The team of UC researchers and their colleagues identified a genetic variant in HRC, named Ser96Ala, which showed an association with worsening ventricular arrhythmias and sudden cardiac death in a group of patients with idiopathic dilated cardiomyopathy. The mechanisms and pathways that link the HRC variant with arrhythmias causing sudden death were identified.<sup>1<\/sup><\/p>\n<div id=\"attachment_157\" style=\"width: 643px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-157\" class=\"wp-image-157 size-full\" src=\"\/wp-content\/uploads\/sites\/37\/2014\/12\/Screen-Shot-2014-12-03-at-3.00.27-PM.png\" alt=\"Screen-Shot-2014-12-03-at-3.00.27-PM\" width=\"633\" height=\"531\" srcset=\"\/wp-content\/uploads\/sites\/37\/2014\/12\/Screen-Shot-2014-12-03-at-3.00.27-PM.png 633w, \/wp-content\/uploads\/sites\/37\/2014\/12\/Screen-Shot-2014-12-03-at-3.00.27-PM-300x251.png 300w\" sizes=\"auto, (max-width: 633px) 100vw, 633px\" \/><p id=\"caption-attachment-157\" class=\"wp-caption-text\">The genetic alteration of Serine to Alanine at amino acid 96 in HRC is associated with sudden cardiac death in dilated cardiomyopathy patients.
