Optimal LDL-C Target in High-risk Patients After PCI

Официальное название

Targeting LDL-C to Less Than 0.8 mmol/L in Patients After PCI With High Risk of Cardiovascular Disease: an Open-label, Assessor-blinded, Randomized Trial (REC-SAFETARGET Trial)

Обзор

Extensive evidence from epidemiological, genetic, and randomized controlled trials (RCTs) of lipid-lowering therapies has firmly established a causal relationship between low-density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (ASCVD), establishing LDL-C as both a pathogenic risk factor and a critical therapeutic target. Lipid-lowering therapies targeting LDL-C have significantly decreased the overall risk in ASCVD patients. Consequently, current guidelines recommend, based on risk stratification, lowering LDL-C levels in high-risk ASCVD patients to \<1.4 mmol/L with a ≥50% reduction from baseline. Findings from PROVE IT-TIMI 22, IMPROVE-IT, ODYSSEY OUTCOMES, and FOURIER-OLE trials suggest that achieving extremely low LDL-C levels may further reduce the risk of cardiovascular events in ASCVD patients without substantially increasing clinically relevant adverse events; however, randomized data was still scarce in supporting this notion. Against these backgrounds, we have designed this trial to investigate whether targeting LDL-C levels \<0.8 mmol/L in high-risk ASCVD patients results in a significant reduction in adverse events compared to targeting LDL-C levels of 0.8-1.4 mmol/L.

Вмешательства

• Другое Intensive LDL-C control
  By Statin, Ezetimibe, or PCSK9i, prescribed according to LDL-C level at baseline and follow-up; For patients with baseline LDL-C level \< 3.0 mmol/L, it is recommended to start lipid control by statin + PCSK9i; for LDL-C level ≥ 3.0 mmol/L, statin + ezetimibe + PCSK9i
• Другое Conventional LDL-C control
  By Statin, Ezetimibe, or PCSK9i, prescribed according to LDL-C level at baseline and follow-up; For patients with baseline LDL-C level \< 3.0 mmol/L, it is recommended to start lipid control by statin alone or statin + ezetimibe; for LDL-C level ≥ 3.0 mmol/L, statin + PCSK9i
