One third Patients of ACS potentially eligible for PCSK9 Inhibitors Treatment, finds study

Key findings of the study were:

The researchers noted that untested patients were more likely to be older, female, from rural areas, to have more comorbidities, to already be on cardioprotective therapies, to present with unstable angina, and were less likely to have invasive interventions.

Among 24 229 tested, they noted 77.5% had at least one lipid value above guideline-recommended threshold (LDL [low-density lipoprotein] ≥1.8 mmol/L [70 mg/dL] and non-HDL [high-density lipoprotein] ≥2.6 mmol/L [100 mg/dL]), of which 38.8% did not have repeat testing within the year after discharge.

They found that lipid testing in the hospital was associated with higher rates of initiation or escalation of statin therapy within 90 days of their ACS adjusted odds ratio, 2.13.

Based on current guidelines for PCSK9 inhibitor therapy, 39.6% of the total patient cohort would have been eligible for treatment. The researchers estimated that 184 cardiovascular events would have occurred over 3.4 years if these guidelines had been followed and the eligible patients had received PSCK9 inhibitor therapy.

The authors concluded, "Within 90 days of incident ACS, ≈80% of patients did not meet guideline-recommended lipid thresholds and more than one-third would potentially be eligible for PCSK9 inhibitors."
