The aim of this study was to analyze the impact of cholesterol levels on 3-month death rates in patients with ischaemic stroke treated with intravenous recombinant tissue plasminogen activator (rtPA) and admitted to a monitored acute stroke unit. The study included 220 patients, average age of 73 years.
(a) Those with the lowest cholesterol, (less than 155 mg/dL or 4.0 mmol/L) had death rates of 25.7%.
(b) Those with cholesterol levels in the middle range, (155-192 mg/dL or 4.0-5.0 mmol/L) had death rates of 13.7%.
(c) Those with the highest cholesterol, (over 192 mg/dL or 5.0 mmol/L) had death rates of 5.5%.
The results of the study show that low cholesterol levels are associated with lower survival rates in stroke patients.
