    Abstract: The TST trial (Treat Stroke to Target) evaluated the benefit of targeting a LDL (low-density lipoprotein) cholesterol of 〈 70 mg/dL to reduce the risk of cardiovascular events in 2860 patients with ischemic stroke with atherosclerotic stenosis of cerebral vasculature or aortic arch plaque 〉 4 mm, in a French and Korean population. The follow-up lasted a median of 5.3 years in French patients (similar to the median follow-up time in the SPARCL trial [Stroke Prevention by Aggressive Reduction in Cholesterol Level]) and 2.0 years in Korean patients. Exposure duration to statin is a well-known driver for cardiovascular risk reduction. We report here the TST results in the French cohort. Methods— One thousand seventy-three French patients were assigned to 〈 70 mg/dL (1.8 mmol/L) and 1075 to 100±10 mg/dL (90–110 mg/dL, 2.3–2.8 mmol/L). To achieve these goals, investigators used the statin and dosage of their choice and added ezetimibe on top if needed. The primary outcome was the composite of ischemic stroke, myocardial infarction, new symptoms requiring urgent coronary or carotid revascularization and vascular death. Results— After a median follow-up of 5.3 years, the achieved LDL cholesterol was 66 (1.69 mmol/L) and 96 mg/dL (2.46 mmol/L) on average, respectively. The primary end point occurred in 9.6% and 12.9% of patients, respectively (HR, 0.74 [95% CI, 0.57–0.94]; P =0.019). Cerebral infarction or urgent carotid revascularization following transient ischemic attack was reduced by 27% ( P =0.046). Cerebral infarction or intracranial hemorrhage was reduced by 28% ( P =0.023). The primary outcome or intracranial hemorrhage was reduced by 25% ( P =0.021). Intracranial hemorrhages occurred in 13 and 11 patients, respectively (HR, 1.17 [95% CI, 0.53–2.62]; P =0.70). Conclusions— After an ischemic stroke of documented atherosclerotic origin, targeting a LDL cholesterol of 〈 70 mg/dL during 5.3 years avoided 1 subsequent major vascular event in 4 (number needed to treat of 30) and no increase in intracranial hemorrhage.

    More Than 50 Percent Reduction in LDL Cholesterol in Patients With Target LDL 〈70 mg/dL After a Stroke
    Ovid Technologies (Wolters Kluwer Health) ; 2023

    Abstract: Whether a strategy to target an LDL (low-density lipoprotein) cholesterol 〈 70 mg/dL is more effective when LDL is reduced 〉 50% from baseline rather than 〈 50% from baseline has not been investigated. METHODS: The Treat Stroke to Target trial was conducted in France and South Korea in 61 sites between March 2010 and December 2018. Patients with ischemic stroke in the previous 3 months or transient ischemic attack within the previous 15 days and evidence of cerebrovascular or coronary artery atherosclerosis were randomly assigned to a target LDL cholesterol of 〈 70 mg/dL or 100±10 mg/dL, using statin and/or ezetimibe as needed. We used the results of repeated LDL measurements (median, 5 [2–6] per patient) during 3.9 years (interquartile range, 2.1–6.8) of follow-up. The primary outcome was the composite of ischemic stroke, myocardial infarction, new symptoms requiring urgent coronary or carotid revascularization, and vascular death. Cox regression model including lipid-lowering therapy as a time-varying variable, after adjustment for randomization strategy, age, sex, index event (stroke or transient ischemic attack), and time since the index event. RESULTS: Among 2860 patients enrolled, patients in the lower target group who had 〉 50% LDL cholesterol reduction from baseline during the trial had a higher baseline LDL cholesterol and a lower LDL cholesterol achieved as compared to patients who had 〈 50% LDL cholesterol reduction (155±32 and 62 mg/dL versus 121±34 and 74 mg/dL, respectively, P 〈 0.001 for both). In the 〈 70 mg/dL target group, patients with 〉 50% LDL reduction had a significant reduction in the primary outcome as compared to the higher target group (hazard ratio, 0.61 [95% CI, 0.43–0.88]; P =0.007) and patients with 〈 50% LDL reduction from baseline had little reduction (hazard ratio, 0.96 [95% CI, 0.73–1.26]; P =0.75). CONCLUSIONS: In this post hoc analysis of the TST trial, targeting an LDL cholesterol of 〈 70 mg/dL reduced the risk of primary outcome compared with 100±10 mg/dL provided LDL cholesterol reduction from baseline was superior to 50%, thereby suggesting that the magnitude of LDL cholesterol reduction was as important to consider as the target level to achieve.

    Abstract: Patients with acute stroke are often accompanied by comorbidities, such as active cancer. However, adequate treatment guidelines are not available for these patients. The purpose of this study was to evaluate the association between cancer and the outcomes of reperfusion therapy in patients with stroke. Methods: We compared treatment outcomes in patients who underwent reperfusion therapy, using a nationwide reperfusion therapy registry. We divided the patients into 3 groups according to cancer activity: active cancer, nonactive cancer, and without a history of cancer. We investigated reperfusion processes, 24-hour neurological improvement, adverse events, 3-month functional outcome, and 6-month survival and related factors after reperfusion therapy. Results: Among 1338 patients who underwent reperfusion therapy, 62 patients (4.6%) had active cancer, 78 patients (5.8%) had nonactive cancer, and 1198 patients (89.5%) had no history of cancer. Of the enrolled patients, 969 patients received intravenous thrombolysis and 685 patients underwent endovascular treatment (316 patients received combined therapy). Patients with active cancer had more comorbidities and experienced more severe strokes; however, they showed similar 24-hour neurological improvement and adverse events, including cerebral hemorrhage, compared with the other groups. Although the functional outcome at 3 months was poorer than the other groups, 36.4% of patients with active cancer showed functional independence. Additionally, 52.9% of the patients with determined stroke etiology showed functional independence despite active cancer. During the 6-month follow-up, 46.6% of patients with active cancer died, and active cancer was independently associated with poor survival (hazard ratio, 3.973 [95% CI, 2.528–6.245]). Conclusions: In patients with active cancer, reperfusion therapy showed similar adverse events and short-term outcomes to that of other groups. While long-term prognosis was worse in the active cancer group than the nonactive cancer groups, not negligible number of patients had good functional outcomes, especially those with determined stroke mechanisms.

    Abstract: d ‐Dimer level is a marker of hypercoagulability, which is associated with thrombus formation and resolution. We investigated the value of d ‐dimer levels in predicting outcomes of acute ischemic stroke in patients who underwent endovascular treatment (EVT). Methods We analyzed data of patients who underwent only EVT from the SECRET (Selection Criteria in Endovascular Thrombectomy and Thrombolytic Therapy) registry. d ‐Dimer levels were routinely measured in 10 of 15 participating hospitals. Patients were grouped into tertiles (tertile 1, tertile 2, and tertile 3) according to d ‐dimer levels (lowest, moderate, and highest, respectively). We compared serial scores on the National Institutes of Health Stroke Scale at baseline, on day 1 of hospitalization, and at discharge; functional outcome 3 months after EVT; and rate of mortality within 6 months after EVT. Results In the 170 patients, the median d ‐dimer level was 477 ng/mL (interquartile range, 249–988 ng/mL). In tertile 3, the National Institutes of Health Stroke Scale score was higher at discharge than on day 1 of hospitalization. Poor outcome 3 months after EVT (modified Rankin Scale score, ≥3) was more common with high d ‐dimer levels (26.3% of tertile 1, 57.1% of tertile 2, and 76.4% of tertile 3; P 〈 0.001). Multivariable analysis showed that a high d ‐dimer level was independently associated with poor outcome 3 months after EVT (odds ratio [OR], 4.399 [95% CI, 1.594–12.135] ). Kaplan–Meier survival analysis showed that a high d ‐dimer level was independently associated with death within 6 months after EVT (OR, 5.441 [95% CI, 1.560–18.978]; log‐rank test, P 〈 0.001). The d ‐dimer effect showed no heterogeneity across the subgroups for poor outcome 3 months after EVT or death within 6 months after EVT. The direction of effect was unfavorable for tertile 3 across all demographic strata. Conclusions High plasma d ‐dimer levels were predictive of early neurologic worsening, poor functional outcome 3 months after EVT, and death within 6 months after EVT.
