title: [X-syndrome: a pending problem].
abstract: The aim of the study was to evaluate the debated question of the pathogenesis of Syndrome X. Twelve consecutive patients with Syndrome X underwent high-dose dipyridamole echocardiographic test. Angina and ischaemic ST depression occurred in all patients, without impairment of regional wall-motion. Microvascular dysfunction probably is the cause of Syndrome X.
