Guideline-directed low-density lipoprotein management in high-risk ischemic stroke or transient ischemic attack admissions in China from 2015 to 2019.

ABSTRACT:

Background

Lowering low-density lipoprotein cholesterol (LDL-C) is crucial for secondary stroke prevention in stroke patients with preexisting cardiovascular diseases (CVD) or cerebrovascular diseases (CeVD). However, data on attainment of guideline-recommended LDL-C levels are lacking.

Methods

We analyzed data from the Chinese Stroke Center Alliance (CSCA) program for patients with ischemic stroke and transient ischemic attack (TIA) hospitalized between August 2015 and July 2019. Participants were classified into different disease groups according to preexisting CeVD (stroke/TIA) or CVD [coronary heart disease (CHD) or myocardial infarction (MI)].

Results

Of 858,509 patients presenting with an acute stroke/TIA, 251,176 (29.3%) had a preexisting CeVD, 44,158 (5.1%) had preexisting CVD, 33,070 (3.9%) had concomitant preexisting CeVD and CVD, and 530,105 (61.7%) had no documented history of CeVD/CVD. Overall, only 397,596 (46.3%) met the target for LDL-C <2.6 mmol/L, 128,177 (14.9%) for LDL-C <1.8 mmol/L and 55,275 (6.4%) for LDL-C <1.4 mmol/L, and patients with concomitant CeVD and CVD had higher attainment rates than other disease groups (P<0.001). Despite improvements over time in the proportion of patients who attain LDL-C targets (P for trend <0.05), it remains suboptimal. Younger age, women, having a history of hypertension or dyslipidemia, current smoking or drinking, and being admitted to hospitals located in eastern China were associated with lower odds of meeting the LDL-C goals.

Conclusions

Overall attainment of guideline LDL-C targets in a population of stroke/TIA patients is low and indicates the need for better management of dyslipidemia, particularly for high-risk stroke patients with pre-existing CeVD or CVD.

Project description:BackgroundPatients with ischemic stroke or transient ischemic attack (TIA) are at increased risk for future cardiovascular events despite current preventive therapies. The identification of insulin resistance as a risk factor for stroke and myocardial infarction raised the possibility that pioglitazone, which improves insulin sensitivity, might benefit patients with cerebrovascular disease.MethodsIn this multicenter, double-blind trial, we randomly assigned 3876 patients who had had a recent ischemic stroke or TIA to receive either pioglitazone (target dose, 45 mg daily) or placebo. Eligible patients did not have diabetes but were found to have insulin resistance on the basis of a score of more than 3.0 on the homeostasis model assessment of insulin resistance (HOMA-IR) index. The primary outcome was fatal or nonfatal stroke or myocardial infarction.ResultsBy 4.8 years, a primary outcome had occurred in 175 of 1939 patients (9.0%) in the pioglitazone group and in 228 of 1937 (11.8%) in the placebo group (hazard ratio in the pioglitazone group, 0.76; 95% confidence interval [CI], 0.62 to 0.93; P=0.007). Diabetes developed in 73 patients (3.8%) and 149 patients (7.7%), respectively (hazard ratio, 0.48; 95% CI, 0.33 to 0.69; P<0.001). There was no significant between-group difference in all-cause mortality (hazard ratio, 0.93; 95% CI, 0.73 to 1.17; P=0.52). Pioglitazone was associated with a greater frequency of weight gain exceeding 4.5 kg than was placebo (52.2% vs. 33.7%, P<0.001), edema (35.6% vs. 24.9%, P<0.001), and bone fracture requiring surgery or hospitalization (5.1% vs. 3.2%, P=0.003).ConclusionsIn this trial involving patients without diabetes who had insulin resistance along with a recent history of ischemic stroke or TIA, the risk of stroke or myocardial infarction was lower among patients who received pioglitazone than among those who received placebo. Pioglitazone was also associated with a lower risk of diabetes but with higher risks of weight gain, edema, and fracture.
