Stroke is a major health problem worldwide. Its pharmacological management includes thrombolytic therapy for the acute phase and antiplatelet drugs for stroke recovery and prevention. Statins can help in the acute phase and in preventing stroke in secondary prevention patients. Policosanol is a cholesterol-lowering drug with concomitant antiplatelet effects, with protective effects in stroke models. This observational study investigated the effects of policosanol (20 mg/day) administered during the acute phase and for 5 years later on the neurological recovery of patients with ischemic stroke treated with antiplatelets and vitamins. After hospital discharge, patients were followed up every 3 (first year) and 6 (thereafter) months. Neurological improvement was assessed with the modified Canadian Neurological Scale. Adverse events were recorded. Fifty patients were included; all completed the study. Neurological score improved throughout the study. No patient died, and most [40 (80.0%)] did not experience new vascular events; only one (2.0%) suffered a new stroke, and two (4.0%) suffered more than one transient ischemic attack. The time to the first recurrent event was 46.2 months. Policosanol persistently lowered serum total cholesterol, with such reduction correlating with the neurological improvement (R = 0.995253301). Triglycerides were unchanged. Treatment was well tolerated. Policosanol administered to patients suffering ischemic stroke treated with aspirin and vitamins showed good results on neurological outcomes and recurrent events. This study, however, has limitations, since it was open and uncontrolled, and patients also consumed aspirin and vitamins. New randomized, controlled studies are needed to assess the usefulness of policosanol in stroke management.
中风是全球范围内的一个主要健康问题。其药物治疗包括急性期的溶栓治疗以及用于中风恢复和预防的抗血小板药物。他汀类药物可在急性期发挥作用,并有助于二级预防患者预防中风。聚戊烯醇是一种具有抗血小板作用的降胆固醇药物,在中风模型中具有保护作用。这项观察性研究调查了急性期及随后5年给予聚戊烯醇(20毫克/天)对接受抗血小板药物和维生素治疗的缺血性中风患者神经功能恢复的影响。出院后,患者在第1年每3个月、之后每6个月接受随访。采用改良的加拿大神经量表评估神经功能改善情况。记录不良事件。纳入了50名患者;所有患者均完成了研究。在整个研究过程中神经评分有所改善。没有患者死亡,大多数患者[40名(80.0%)]未发生新的血管事件;只有1名患者(2.0%)发生了新的中风,2名患者(4.0%)发生了不止一次短暂性脑缺血发作。首次复发事件的时间为46.2个月。聚戊烯醇持续降低血清总胆固醇,这种降低与神经功能改善相关(R = 0.995253301)。甘油三酯未发生变化。治疗耐受性良好。给予接受阿司匹林和维生素治疗的缺血性中风患者聚戊烯醇,在神经功能转归和复发事件方面显示出良好效果。然而,这项研究存在局限性,因为它是开放性且无对照的,并且患者同时还服用了阿司匹林和维生素。需要开展新的随机对照研究来评估聚戊烯醇在中风治疗中的有效性。
