BACKGROUND: Hyperlipidemia is one of the major risk factors for cerebrovascular disease and it is common practice to obtain fasting lipid profile prior to starting lipid lowering therapy (LLT). Recent AHA Guidelines published in 2018 allow for a non-fasting value to be used. OBJECTIVE: To determine if obtaining fasting lipid levels in addition to random lipid levels prompts changes in hyperlipidemia management of acute stroke patients. METHODS: 206 patients met the study criteria which included a diagnosis of acute ischemic stroke or transient ischemic attack on admission and availability of both random and fasting LDL levels collected within 72 h of each other. Patients were divided into three groups based on random LDL at admission: Group A: LDL < 70, Group B: LDL 70-99, and Group C: LDL ≥ 100 mg/dL. The dataset was analyzed to conform to the 2018 AHA/ACC guidelines using an LDL cutoff of 70 mg/dL. RESULTS: In 206 patients, statin management would change based on the fasting LDL level in 12 patients, 11 of whom were in Group B. Our data suggests that lipid management is more likely to change if the initial random LDL falls between 70-99 mg/dL as compared to a value outside of this range (P < 0.001). We present a decision algorithm to guide lipid management in acute stroke patients. CONCLUSIONS: Foregoing a fasting lipid panel to guide LLT in patients with ischemic stroke is appropriate in most cases but for select patients with random LDL levels between 70 and 99, fasting lipid profile should be obtained prior to deciding upon LLT.
