Prior use of statins improves outcome in patients with intracerebral hemorrhage: prospective data from the National Acute Stroke Israeli Surveys (NASIS).

BACKGROUND AND PURPOSE: Intracerebral hemorrhage (ICH) is a deadly form of stroke. Pretreatment with statins exerts protective effects in patients with ischemic stroke, but their effects in patients with ICH remains unclear. METHODS: The National Acute Stroke Israeli Surveys (NASIS) included all patients admitted with acute stroke to any of the 28 hospitals nationwide during February through March 2003 and March through April 2007. We compared stroke severity and outcomes of ICH patients who received statins before the index event with those who did not, using multivariable logistic regression models adjusting for the propensity to use statins before the event. RESULTS: Among 3212 stroke patients, 312 had ICH and 89 of them were receiving statins at the time of the ICH. Patients on statins before ICH had lower baseline NIHSS scores, less systemic complications, higher proportions of good outcome (modified Rankin scale 0 to 3), lower death rates, and higher rates of discharge home or to a rehabilitation facility. On logistic regression analyses statin use before the event was associated with odds ratios of 0.46 for having a severe stroke defined as baseline NIHSS >15 (95% CI; 0.23 to 0.93), 2.97 for having good outcome (95% CI; 1.25 to 7.35) at discharge, and 0.25 for death or nursing facility disposition (95% CI; 0.09 to 0.63). CONCLUSIONS: Use of statins before ICH is associated with reduced mortality and neurological disability and with a higher chance for good outcome, suggesting that statins may be protective in the setting of ICH.

Novel therapies for acute ischemic stroke.

Acute ischemic stroke is one of the leading causes of mortality and chronic disability in the western world. Yet, despite the enormous socioeconomic burden that it imposes, therapies to combat AIS are not widely available. Moreover, revascularization of the ischemic tissue with tissue plasminogen activator, the only FDA-approved therapy for AIS, is hampered by a very narrow therapeutic time window and is only used in a minority of patients. Cerebral ischemia leads to brain damage caused by several pathologic mechanisms that can potentially be blocked by neuroprotective drugs that aim to salvage the ischemic penumbra. However, despite numerous clinical trials, no single drug candidate has proved efficacious in AIS. The current situation calls for novel therapeutic strategies to be used in acute ischemic stroke. This review surveys some of these novel and promising cutting edge therapies.
