Project description:<p>The Massachusetts General Hospital (MGH) Atrial Fibrillation Study was initiated in 2001. The study has enrolled serial probands, unaffected and affected family members with atrial fibrillation. At enrollment participants undergo a structured interview to systematically capture their past medical history, AF treatments, and family history. An electrocardiogram is performed; the results of an echocardiogram are obtained; and blood samples are obtained.</p> <p><b>The Massachusetts General Hospital (MGH) Atrial Fibrillation Study is utilized in the following dbGaP substudies.</b> To view genotypes, analysis, other molecular data, and derived variables collected in these substudies, please click on the following substudies below or in the "Substudies" box located on the right hand side of this top-level study page phs001001 Massachusetts General Hospital (MGH) Atrial Fibrillation Study. <ul> <li><a href="./study.cgi?study_id=phs001116">phs001116</a> MGH AF CHARGE-S</li> <li><a href="./study.cgi?study_id=phs001117">phs001117</a> MGH AF Exome Sequencing</li> <li><a href="./study.cgi?study_id=phs001118">phs001118</a> MGH AF Medical Resequencing</li> </ul> </p>
Project description:Atrial fibrillation (AF) is the most common persistent arrhythmia that affect 1–2% of the general population. People with AF display an array of complications cardiogenic stroke and systemic embolism caused by hemodynamic instability and blood hypercoagulability in clinical practice. However, it’s still unclear whether and how ubiquitylated proteins react to AF in the left atrial appendage of patients with AF and valvular heart disease. This theory focuses on the changes of ubiquitylated proteins in atrial fibrillation associated with heart valve disease. We firstly widely analysis the proteins ubiquitination in patients with atrial fibrillation.

Early-onset atrial fibrillation was defined as an age of onset prior to 66 years of age.</p> <p>Comprehensive phenotypic and pedigree data for study participants are available through dbGaP <a href="./study.cgi?study_id=phs001001">phs001001</a>.</p>
