| Research Abstract |
Atrial fibrillation (AF) has an enormous social impact because of its very high incidence, its potential for devastating clinical consequences, and the difficulty of its management . Hypertrophic cardiomyopathy (HCM) is well known risk factor for AF. However, significant proportions of patients, up to 30% in some large studies, develop AF in the absence of risk factors. We performed genetic analysis for 75 patients with lone or familial AF, and identified 3 mutations. We also clarified that the HCM patients with angiotensinogen 1 A/C polymorphism, TNNT2 mutation, or TNNI3 mutation easily develop AF compared to those without these polymorphism or mutations.
