Microbleeding on MRI as a marker for hemorrhage after stroke thrombolysis.
-
Obvious cardiac dysfunction, including ECG abnormalities and left ventricular asynergy, is known to develop after subarachnoid hemorrhage (SAH). To clarify the close relationship between myocardial damage and sympathetic nervous activity immediately after SAH, a novel experimental animal model was used. ⋯ These results suggest that the elevated activity of the sympathetic nervous system observed in the acute phase of SAH induced myocardial damage and contributed to the development of cardiac dysfunction.

Comparative Study
Acute ischemic stroke patterns in infective and nonbacterial thrombotic endocarditis: a diffusion-weighted magnetic resonance imaging study.
Although infective endocarditis (IE) and nonbacterial thrombotic endocarditis (NBTE) are associated with cardioembolic stroke, differences in the nature of these conditions may result in differences in associated stroke patterns. We compared patterns of acute and recurrent ischemic stroke in IE and NBTE, using diffusion-weighted MRI (DWI). ⋯ DWI has utility in differentiating between IE and NBTE. Patients with NBTE uniformly have multiple, widely distributed, small and large strokes, whereas patients with IE exhibit a panoply of stroke patterns.

Multicenter Study Clinical Trial
Guideline compliance improves stroke outcome: a preliminary study in 4 districts in the Italian region of Lombardia.
Guidelines for medical practice in stroke have been proposed in different countries, but their impact on stroke outcome has not been verified to date. The aim of this study was to evaluate the impact of the American Heart Association guidelines for acute stroke and for transient ischemic attack on first-ever stroke patients. ⋯ This study demonstrates an association between adherence to guidelines and stroke outcome, and it can be viewed as a study that prepares the way for a randomized controlled trial in this area. It also emphasizes the need to develop personnel and structures devoted to stroke care because an evidence-based clinical approach could significantly reduce the risk of death.
