Effects of clinical and laboratory variables and of pretreatment with cardiovascular drugs in acute ischaemic stroke: A retrospective chart review from the GIFA study

subject

description

Background: Few studies have examined the role of cardiovascular drugs on acute ischaemic stroke prognosis. Aims: To evaluate the relationship between a favourable outcome in patients with acute ischaemic stroke and specific demographic, clinical and laboratory variables and cardiovascular drug pretreatment. Methods: The 1096 patients enrolled in the GIFA study (who had a main discharge diagnosis of ischaemic stroke) represent the final patient sample used in this analysis. Drugs considered in the analysis included angiotensin converting enzyme (ACE)-inhibitors, angiotensin II receptor blockers, statins, calcium channel blockers, anti-platelet drugs, vitamin K antagonists and heparins. The outcomes analyzed included in-hospital mortality, cognitive function evaluated by the Hodkinson Abbreviated Mental Test (HAMT), and functional status evaluated by activities of daily living (ADL). The definition of a good outcome was no in-hospital mortality, a HAMT score of >= 6 and no ADL impairment. Results: Patients with no in-hospital mortality, a HAMT score of >6 and no ADL impairment were more likely to be younger at baseline and have a lower blood glucose level and a systolic blood pressure (SBP) between 120 and 180 mmHg, a higher plasma total cholesterol level, a lower white blood cell count, and a lower Charlson Index (CI) score, a higher rate of pretreatment with ACE-inhibitors, calcium channel blockers and a lower rate of pretreatment with heparin. Conclusions: Predictors of good outcome, in terms of in-hospital mortality and cognitive and functional performance at discharge, included higher SBP at admission between 120 and 180 mmHg, a SBP plasma total cholesterol levels, a lower CI score, and pretreatment with ACE-inhibitors, calcium channel blockers and anti-platelets.
