Histological substrate of atrial biopsies in patients with lone atrial fibrillation.
BACKGROUND Lone atrial fibrillation (LAF) is a common clinical syndrome, but its origin remains unknown. METHODS AND RESULTS We performed endomyocardial biopsies of the right atrial septum (2 to 3Expand

Myocardial production of chromogranin A in human heart: a new regulatory peptide of cardiac function.
AIMS High chromogranin-A (CgA) levels were observed in patients with heart failure but its source remained uncertain. We evaluated whether CgA is produced by myocardium and might affect myocardialExpand

Impairment of cardiac autonomic function in patients with Duchenne muscular dystrophy: relationship to myocardial and respiratory function.
BACKGROUND Previous studies reported an impairment of nervous autonomic activity in patients with Duchenne muscular dystrophy (DMD). However, the relationship of the autonomic dysfunction to theExpand
