title: [Clinical aspects and diagnostic criteria in non-obstructive symmetric hypertrophic myocardiopathy].
abstract: We describe the clinical data, the standard and Holter electrocardiographic observations, the carotid pulse tracings, the M-mode and B-mode echocardiographic findings and the left ventriculographic aspects of 21 patients with non-obstructive symmetric hypertrophic cardiomyopathy (NOSHCM). NOSHCM was diagnosed when there was echocardiographic and/or left ventriculographic evidence of septal and posterior wall hypertrophy without signs of left ventricular outflow destruction (LVOTO). Compared to the asymmetric hypertrophic obstructive cardiomyopathy (AHOCM), NOSHCM reveals reduced excursion of the posterior wall of the left ventricle, whereas patients with AHOCM have more frequently systolic murmurs and carotid pulse changes suggestive of LVOTO. Proper classification and treatment of NOSHCM are discussed.
