Impact of a personalized, strike early and strong lipid-lowering approach on low-density lipoprotein-cholesterol levels and cardiovascular outcome in patients with acute myocardial infarction

Considering the lack of evidence, we evaluated the impact on cardiovascular outcome of the systematic introduction in our institution of a personalized strike early and strong (SES) approach for lipid-lowering therapy (LLT) in patients admitted for acute myocardial infarction (MI).

We retrospectively analysed data from 500 consecutive patients hospitalized across three periods: Period A (N = 198, January–June 2019), when the low-density lipoprotein cholesterol (LDL-C) goal was <70 mg/dL and a stepwise LLT approach was recommended; Period B (N = 180, January–June 2021), when the LDL-C goal was <55 mg/dL and a stepwise approach was recommended; Period C (N = 122, January–June 2023), when the LDL-C goal was <55 mg/dL and our SES protocol was implemented. Primary endpoints were achievement of the LDL-C goal during follow-up and 1-year incidence of major adverse cardiovascular events (MACE). Compared to the other periods, in Period C, there was a higher use of potent statins, alone or in combination with ezetimibe, and of proprotein convertase subtilisin/kexin type 9 inhibitor inhibitors at discharge. This translated into higher achievement of the LDL-C goal (83% vs. 55% in Period A and 43% in Period B; P < 0.001) and reduced incidence of MACE (3% vs. 12% and 11%; P = 0.026). MACE rates were lowest in patients with early and sustained LDL-C <55 mg/dL and in those achieving both LDL-C <55 mg/dL and ≥50% LDL-C reduction.

The systematic introduction of a personalized, SES strategy for LLT in patients with acute MI led to greater achievement of LDL-C goal and lower risk of MACE at 1 year vs. the stepwise approach.
