Transient Increase in intrathoracic Pressure as a Contributing Factor to Cardioembolic Stroke

Abstract

Background The hemodynamic effects of increased intrathoracic pressure (ITP) have been the focus of many investigations However very little is known about the effects of elevated ITP on the occurrence of stroke Case Report Four young patients with a cardioembolic source of stroke were examined In all cases the stroke was preceded by an increase in TIP that occurred during coughing, vomiting or sexual intercourse Conclusions We suggest that cardioembolic stroke is facilitated by situations in which TIP is elevated J Clin Neurol 2010 6 212-215
