Achievement of target LDL-cholesterol level in patients with acute coronary syndrome undergoing percutaneous coronary intervention: The JET-LDL registry

Impact of a personalized, strike early and strong approach on non-HDL-cholesterol levels and outcome in patients with acute myocardial infarction

AIMS

We retrospectively evaluated the impact on non-HDL-cholesterol (non-HDL-C) levels of the systematic introduction in our institution of an individualized, pre-defined, strike early and strong (SES) strategy for lipid-lowering therapy (LLT) in patients with acute myocardial infarction (MI).

METHODS

We analyzed data from 500 consecutive patients admitted across three periods: Period A (N = 198, January-June 2019), when the non-HDL-C goal was <100 mg/dL and a stepwise LLT approach was indicated; Period B (N = 180, January-June 2021), when the non-HDL-C goal was <85 mg/dL and a stepwise approach was recommended; Period C (N = 122, January-June 2023), when the SES protocol was introduced. Primary endpoints were the percentage of patients reaching the non- HDL-C goal during follow-up and the incidence of major adverse cardiovascular events (MACE) at one year.

RESULTS

Compared to the other periods, the prevalence of prescription at discharge of potent statins, alone or in combination with ezetimibe, and PCSK9 inhibitors was greater in Period C. The achievement of the non-HDL-C goal in Period C was higher (87 % vs 67 % and 58 % in Periods A and B, respectively; p < 0.001). This achievement was associated with a lower occurrence of MACE (7 % vs. 13 % in patients not at target; log-rank p = 0.027). MACE incidence was the lowest in patients with early and sustained non-HDL-C < 85 mg/dL during follow-up.

CONCLUSION

The systematic introduction of an individualized, SES approach for LLT in patients with acute MI led to higher achievement of the non-HDL-C goal and this translated into a lower risk of MACE.

PCSK9 Inhibitors "Fast Track" Use Versus "Stepwise" Lipid-Lowering Therapy in Patients with Acute Coronary Syndrome: A Retrospective Single-Center Study in a "Real-World" Population

Background: The "fast track" addition (within 48 h) of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) to the optimized oral lipid-lowering therapy (LLT) during hospitalization for acute coronary syndrome (ACS) has been shown to rapidly achieve the low-density lipoprotein cholesterol (LDL-C) therapeutic targets. However, so far, its efficacy in real-world settings remains understudied. Methods: We retrospectively analyzed 128 ACS patients treated at our center, comparing "PCSK9i fast track" use within 48 h to standard "stepwise" LLT. Lipid levels and incidence of major adverse cardiovascular events (MACEs) were evaluated at 30 and 180 days. Results: The "PCSK9i fast track" group achieved significantly lower LDL-C levels at 30 days (41.5 ± 27.5 vs. 85.6 ± 35.9 mg/dL, p < 0.001) and 180 days (29.6 ± 21.0 vs. 59.0 ± 32.4 mg/dL, p < 0.001). Recommended LDL-C targets (<55 mg/dL) were met by 88.3% of the "PCSK9i fast track" group at 180 days, compared with 61.9% of controls (p < 0.001). No significant differences in MACEs were observed between groups. No adverse effects from PCSK9i use were noted. Conclusions: The "PCSK9i fast track" strategy was safe and effective in achieving LDL-C targets more rapidly than conventional approaches in real-world ACS patients.

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

AIMS

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).

METHODS AND RESULTS

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.

CONCLUSION

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.

Low-Density Lipoprotein Cholesterol Goal Achievement and Self-Reported Medication Adherence: Insights from the JET-LDL Registry

In patients with recent acute coronary syndromes (ACS), current guidelines recommend a low-density lipoprotein cholesterol (LDL-C) level <55 mg/100 ml. Despite the widespread use of different potent lipid-lowering therapies (LLT), this goal is not always achieved, often owing to less medication adherence. In this prespecified subanalysis of the JET-Low Density Lipoprotein (JET-LDL) registry, we sought to evaluate the relation between LDL-C targets achievement and LLT adherence in a cohort of patients hospitalized for ACS. The patients' self-reported medication adherence was assessed using the Morisky Medication Adherence Scale (MMAS) at 3-month follow-up. Depending on the score obtained, the population was divided into 2 groups: high adherence (HA, MMAS ≥6) versus low adherence (LA, MMAS <6). The occurrence of the primary end point (LDL-C reduction >50% from baseline or level <55 mg/100 ml at 1 month) was compared in the 2 groups. A total of 963 patients were included in the present analysis; in 277 cases (28.7%), an MMAS score <6 was reported (LA group), whereas in the remaining 686 (71.3%), the score obtained was ≥6 (HA group). No difference between the 2 groups was observed regarding LDL-C levels at admission and LLT prescribed at discharge. At 1 month, the primary end point occurred in 62.5% of cases, with a statistically significant difference between the 2 groups (LA 60% vs HA 65%, p = 0.034). At multivariate logistic regression analysis, LA was identified as an independent predictor of not achieving the primary end point (odds ratio 0.48, 0.39 to 0.85, p = 0.006). In conclusion, in a real-world cohort of patients with ACS, less medication adherence to LLT was a common event (28.7%), negatively affecting LDL-C goal achievement.
