Statins can reduce the risk of stroke in at-risk populations and improve survival after acute ischemic stroke (AIS) among patients with previous statin use. This study aimed to investigate the impact of statin use before AIS onset on in-hospital mortality and identify the factors related to in-hospital mortality among patients with and without previous statin use. A retrospective cohort study of all patients with AIS attending hospital from June 1, 2008 to December 31, 2008. Data were collected from medical records including demographic information, diagnostic information, risk factors, previous statin use, and vital discharge status. Chi-square, Fisher's exact tests, student's t-test, and Mann-Whitney U test, whatever appropriate, were used to test the significance between the variables, and multiple logistic regression was used to identify factors associated with in-hospital mortality. Altogether, 386 patients with AIS were studied, of which 113 (29.3%) had a documented previous statin use. A total of 62 (16.1%) patients with AIS died in hospital. In-hospital mortality was significantly lower among previous statin users (P = 0.013). The presence of atrial fibrillation (AF) increased in-hospital mortality among patients with or without previous statin use. The independent predictors for in-hospital mortality among AIS patients without previous statin use were the presence of diabetes mellitus (P = 0.047), AF (P = 0.045), and renal impairment (P < 0.001). The prophylactic administration of statins significantly reduces post-AIS in-hospital mortality. Furthermore, the identification of predictors of in-hospital mortality might reduce death rates and enhance the application of specific therapeutic and management strategies to patients at a high risk of dying

Introduction: Angiotensin-converting enzyme inhibitors (ACEIs) have shown promising results in decreasing the incidence and the severity of ischemic stroke in populations at risk and in improving ischemic stroke outcomes.
Objectives: The objectives of this study were to investigate the impact of ACEI use before ischemic stroke onset on in-hospital mortality and to identify the independent predictors of in-hospital mortality among patients with ischemic stroke. Methods and Materials: A retrospective cohort study of all patients with acute ischemic stroke attending the hospital from June 1, 2008 to November 30, 2008 was performed. Data were collected from medical records and included demographic information, diagnostic information, risk factors, previous ACEI use, and vital discharge status. Statistical Package for Social Sciences (SPSS) version 15 was used for data analysis. Results: A total of 327 patients with acute ischemic stroke were studied, of which 119 (36.4%) had documented previous ACEI use. During the study period, 52 (15.9%) of the patients with acute ischemic stroke died in hospital. In-hospital mortality was significantly lower among patients who were on ACEI before the attack (P = 0.002). The independent predictors for in-hospital mortality among patients with ischemic stroke were age ≥65 years (P < .001), the presence of diabetes mellitus (P = .012), renal impairment (P = .002), and heart failure (P = .001). Moreover, prior use of ACEI was an independent predictor for survival after ischemic stroke attack (P < .001).
Conclusion: This study provides evidence that the prophylactic administration of ACEI before ischemic stroke may be a potential life-saving strategy. Furthermore, knowledge of in-hospital mortality predictors is necessary to improve survival rate after acute stroke.
Objective: Stroke is a major health problem, yet no studies on stroke have been reported from Palestine. This one-year, hospital-based study was conducted to determine the prevalence of risk factors and the in-hospital mortality rate in patients with ischemic stroke.
Method: All patients admitted to Al-Watani government hospital and diagnosed with ischemic stroke between September 2006 and August 2007 were included in the study. Data were obtained by retrospective review of medical charts. Pearson Chi-square and independent t test were used in the univariate analysis. Multiple logistic regression analysis was used to determine the independent predictors of in-hospital mortality rates among the patients. Statistical testing and graphics were carried out using SPSS 15.
Results: We identified 153 ischemic stroke patients (83 females and 70 males) of whom 92 were having a first-ever stroke (FES). Patients had several prevalent modifiable risk factors such as hypertension (HTN) (66%), diabetes mellitus (DM) (45.8%), and renal reduced renal function (crcl < 60 ml/ min) (33.9%). Twenty-six (17%) of the patients died during hospitalization. Four variables were significantly associated with in-hospital mortality: history of previous stroke (P= 0.004), crcl at admission (P=0.004), number of post-stroke complications (P=0.001), and age (P=0.043). Multiple logistic regression analysis indicated that the number of post-stroke complications (P= 0.001) and previous stroke (P=0.03) were significant independent predictors of in-hospital mortality.
Conclusion: Screening and better control of risk factors, especially HTN, DM and renal dysfunction, are required to decrease the incidence and in-hospital mortality among patients with ischemic stroke.
