Insights
Very-high-risk (VHR) patients with atherosclerotic cardiovascular disease (ASCVD) in China have a greater disease burden and higher cardiovascular event risk. Current statin use and low-density lipoprotein cholesterol (LDL-C) achievement are suboptimal in this population.
Area of Science:
- Cardiology
- Public Health
- Clinical Medicine
Background:
- Atherosclerotic cardiovascular disease (ASCVD) risk stratification is continuously refined, with recent definitions of very-high-risk (VHR) underutilized in China.
- Understanding the characteristics and outcomes of VHR patients in China is crucial for improving cardiovascular care.
Purpose of the Study:
- To identify patients at VHR according to the 2018 AHA/ACC guideline within a Chinese ASCVD population.
- To evaluate the clinical characteristics, low-density lipoprotein cholesterol (LDL-C) management, and prognostic value of VHR status for cardiovascular events (CVEs).
Main Methods:
- Enrolled 9944 patients with ASCVD.
- Identified VHR patients using the 2018 AHA/ACC guideline.
- Median follow-up of 36.4 months to assess clinical characteristics, LDL-C levels, and CVEs.
Main Results:
- 26% of patients were classified as VHR, with higher prevalence in males, younger individuals (<45 years), and those from low-income regions.
- VHR patients exhibited higher rates of risk factors, more severe coronary stenosis, and increased cardiovascular events compared to non-VHR patients.
- Suboptimal management was observed, with only 3% on high-intensity statins and 13% achieving the LDL-C goal (<1.4 mmol/L).
Conclusions:
- Patients identified as VHR in China carry a significant ASCVD burden, demonstrate poor LDL-C control, and face elevated risks of CVEs.
- The findings suggest a need for refined ASCVD risk stratification and improved management strategies for VHR patients in China.
Background:
Continuous refinement of atherosclerotic cardiovascular disease (ASCVD) stratification has raised the definition of very-high-risk (VHR) recently, which has been underutilized in China. We aimed to identify patients at VHR and evaluate their performances in a Chinese population.
Methods:
A total of 9944 patients with ASCVD was continuously enrolled. Patients at VHR was identified according to 2018 AHA/ACC guideline. Median follow-up was 36.4 months. Clinical characteristics, low-density lipoprotein cholesterol (LDL-C) achievements, and the prognostic value of VHR mapping for cardiovascular events (CVEs) were evaluated.
Findings:
Overall, 26% (2542/9944) of patients were deemed as VHR, which were subsequently divided into two subgroups of VHR-1 [31% (779/2542)] and VHR-2 [69% (1763/2542)]. The rates of VHR were higher among patients of male (30%,2157/7268), young with age <45 years (46%,518/1130), and low-income regions (27%, 498/1838). Patients at VHR carried higher rates of risk factors than those at non-VHR (all p<0.001). However, only 3% (80/2542) of patients at VHR were prescribed with high-intensity of statins, and just 13% (321/2542) of them reached the LDL-C goal (<1.4mmol/L). Furthermore, of patients with coronary stenosis (n=9806), multiple-diseased vessels (47%, 1192/2523 vs. 36%,2587/7283) and occlusive lesions (36%, 902/2523 vs. 13%, 949/7283) were detected more commonly in those at VHR than non-VHR. The adjusted hazard ratios of VHR-1 and VHR-2 for primary CVEs were 2.58(1.61-4.14) and 2.23(1.55-3.20), respectively.
Interpretation:
Our study firstly reported that patients at VHR carried more severe ASCVD burden, lower LDL-C achievement, and higher CVEs risk, suggesting that the refinement of ASCVD might be considered in China to further understand patients at VHR.
