Impact of LDB3 gene polymorphisms on clinical presentation and implantable cardioverter defibrillator (ICD) implantation in Chinese patients with idiopathic dilated cardiomyopathy.

Objective: Mutations in LIM domain binding 3 (LDB3) gene cause idiopathic dilated cardiomyopathy (IDCM), a structural heart disease with a complicated genetic background. However, the association of polymorphisms in the LDB3 gene with susceptibility to IDCM in Chinese populations remains unexplored as dose the impact on clinical presentation.

Methods: We sequenced all exons and the adjacent part of introns of the LDB3 gene in 159 Chinese Han IDCM patients and 247 healthy controls.

[Clinical study of idiopathic dilated cardiomyopathy complicated by left ventricular aneurysm].

Objective: To examine the hemodynamic and electrophysiological influence of left ventricular aneurysm (LVA) formation in patients with idiopathic dilated cardiomyopathy (IDCM).

Methods: All hospital records were retrospectively reviewed from IDCM patients admitted to our hospital between 2003 and 2008. Patients with coronary angiography evidenced ischemic cardiomyopathy were excluded.
