Coronary disease & ACSCohort study
Determinants of postdischarge low-density lipoprotein cholesterol (LDL-C) testing and target attainment after acute coronary syndrome: A 10-year population-based study
- population-based study
- consecutive acute coronary syndrome (ACS) hospitalizations
- large healthcare system
- multivariable logistic regression
Authors' conclusion
LDL-C follow-up and attainment after ACS remain suboptimal. Patients at risk for absent testing may be recognized before discharge, creating opportunities for proactive intervention. Intensive LLT was associated with better LDL-C control, emphasizing the value of coordinated follow-up strategies.
Study context
- Population
- Patients hospitalized with acute coronary syndrome (ACS) between 2013 and 2023 who survived ≥6 months post-ACSunderwent LDL-C testing 22,722 · did not undergo LDL-C testing 19,334
- Participants
- 42,056 eligible patients
- Exposure
- Factors associated with absence of LDL-C testing and failure to achieve LDL-C < 70 mg/dL
- Testedn = 22,722
- Not testedn = 19,334
Main finding
As reported in the abstract
LDL-C testing · within 6 months postdischarge
Observational data: associations, not effects.

| Absence of early postdischarge LLT dispensing · strongest predictor of nontesting | 7.90 (7.10–8.81) | |
| Combination therapy · lower odds of nontesting | 0.79 (0.69–0.90) | |

LDL-C < 70 mg/dL attainment among tested patients
| Comparison | Tested | Not tested | OR (95% CI) | |
|---|---|---|---|---|
| Combination therapy · higher target attainment | 59.7% | Not reported in the abstract | 1.52 (1.26–1.83) | |

- Factors associated with nontesting — Nontesting associated with younger age, male sex, lower socioeconomic status, and reduced use of lipid-lowering therapy (LLT) at discharge
- all P < .001
LDL-C < 70 mg/dL attainment among tested patients
- LDL-C control improved over time, paralleling evolving guidelines
