Doppler echocardiographic characteristics of sinus of valsalva aneurysms.

abstract：BACKGROUND:Bleeding is associated with adverse outcome in acute coronary syndromes. However, the precise pathophysiologic mechanisms have not been elucidated. We sought to determine the relationship between bleeding and myocardial ischemia detected by concurrent continuous electrocardiogram (ECG) monitoring and their i...
