Abstract:
:Secondary worsening of stroke symptoms is described in 13-37% of stroke patients, but the exact mechanism of this phenomenon remains unclear. The aim of this study is to find prognostic variables in correlation to secondary worsening of stroke symptoms in patients with lacunar or cortical strokes. In this prospective observational study we included all patients with ischaemic stroke; patients with transient ischaemic attack were excluded. Patients undergoing thrombolysis and becoming symptom-free after 24 h were still included in our analyses. Secondary worsening of stroke symptoms was defined as an increase of two or more points on the NIH Stroke Scale (NIHSS). The NIHSS score was assessed on admission, at discharge, and when patients had symptoms that indicated worsening of stroke. Applying univariate and multivariable analysis, we studied the relation between symptoms indicating secondary worsening of stroke and prognostic variables such as extreme nocturnal blood pressure falls (>20% of the average blood pressure), infection, diabetes mellitus, hypertension, smoking, dyslipidaemia, a history of cardiovascular or cerebrovascular disease and thrombolysis. This study included 202 patients with a mean age of 72 years, 48.8% were men and 43% had a lacunar stroke. Secondary worsening of stroke symptoms occurred in 13.5% of all patients, more often but not significantly (NS) after lacunar than cortical strokes (16.8 and 11.4%, respectively), and in patients with extreme nocturnal blood pressure falls versus without (15.6 and 11.8%, respectively (NS)). There was no significant relation between the analysed prognostic variables and secondary worsening of stroke symptoms. This study did not show significant correlation between several variables and secondary worsening of stroke symptoms in patients with recent ischaemic stroke.
