OBJECTIVE: If the present data defining the prognostic predictors is examined carefully, a serious contradiction is noticed. In this study, we tried to determine which factors affect the sixth month mortality, recurrence and functional recovery measured quantitatively after ischemic stroke, among our own patients followed in a tertiary health care center.
METHODS: Age, sex, the presence of hypertension, coronary heart disease, atrial fibrillation, diabetes mellitus, hyperlipidemia, previous stroke, stroke subtype, admittance mean blood pressure, admittance blood sugar, hemotocrit, the presence of left ventricle hypertrophy and ejection fraction was recorded for 223 patients with ischemic stroke. The scores for National Institute of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS) and Barthel Index (BI) were recorded at the beginning and at the end of six months. The correlation of these 14 clinical and laboratory parameters with mortality, recurrence and recovery was examined statistically.
RESULTS: Mortality rate was 33%, recurrence rate was 3.8%. Factors related with mortality were age, female gender, coronary artery disease, atrial fibrillation, low ejection fraction, low hematocrit and high admittance blood glucose (p< 0.05). Mortality was significantly low among patients with hyperlipidemia (p< 0.05). There was no statistically significant correlation between stroke recurrence and any of parameters investigated (p> 0.05). In the multivariate analyses, only, the effect of age, gender and hyperlipidemia on mortality was persisting (p< 0.05). Considering NIHSS, patients with high mean admittance blood pressure, considering mRS and BI younger patients and patients with lacunar infarcts had better recovery levels, while patients with previous strokes had poorer recovery (p< 0.05).
CONCLUSION: Higher age and high admittance blood sugar were the most important determinants of mortality after ischemic stroke. Hyperlipidemia reduces the risk of death after stroke probably because of the neuroprotective effects of lipid lowering drugs. None of these parameters clearly affect functional recovery at the end of six month.
