Effect of Cardioembolic Etiology on Intravenous Thrombolysis Efficacy for Acute Ischemic Stroke.

Previous clinical studies suggest that intravenous (IV) recombinant tissue plasminogen activator (rt-PA) benefits stroke patients regardless of the underlying etiology. In this study, we assessed the possible differences in response to IV rt-PA between cardioembolic stroke and other stroke subtypes. A total of 303 consecutive stroke ischemic patients (from January 2005 to April 2014) admitted to our Stroke Unit and treated with IV rt-PA were retrospectively reviewed.

HIV-related pulmonary hypertension. From pathogenesis to clinical aspects.

HIV-related pulmonary hypertension (HIV-PH) is a cardiovascular complication of HIV infection that has been recognized in the last years with increasing frequency. HIV-related pulmonary hypertension is a clinical disorder which carries a bad prognosis. While a direct HIV infection of the pulmonary vessels in the pathogenesis of this disorder was not demonstrated, currently a multifactorial pathogenesis of this disease could be hypothesized.
