Are elevated apolipoprotein B (apoB) and/or non-high-density lipoprotein (non-HDL) cholesterol superior to elevated low-density lipoprotein (LDL) cholesterol in identifying statin-treated patients at residual risk of all-cause mortality and myocardial infarction?

In one paragraph

ApoB Home Test Kit (J Am Coll Cardiol 2021, PMID 33736827) — discordant high apoB with low LDL cholesterol yielded hazard ratios of 1.21 for all-cause mortality and 1.49 for myocardial infarction. The abstract for ApoB Home Test Kit states no limitations.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

ApoB and non-HDL cholesterol are better indicators of residual risk for death and heart attack in statin-treated patients than LDL cholesterol.

The question

Are elevated apolipoprotein B (apoB) and/or non-high-density lipoprotein (non-HDL) cholesterol superior to elevated low-density lipoprotein (LDL) cholesterol in identifying statin-treated patients at residual risk of all-cause mortality and myocardial infarction?

What they tested

The study sought to determine if elevated apoB and/or non-HDL cholesterol are superior to elevated LDL cholesterol in identifying statin-treated patients at residual risk of all-cause mortality and myocardial infarction.

How they did it

The study included 13,015 statin-treated patients from the Copenhagen General Population Study with a median follow-up of 8 years. Cox regressions were used to examine associations between apoB, non-HDL cholesterol, and LDL cholesterol with all-cause mortality or myocardial infarction, both on continuous scales and by categories of concordant and discordant values defined by medians.

What they found

High apoB and non-HDL cholesterol were associated with increased risk of all-cause mortality and myocardial infarction, while high LDL cholesterol showed no such associations. Discordant high apoB with low LDL cholesterol yielded hazard ratios of 1.21 for all-cause mortality and 1.49 for myocardial infarction. Discordant high non-HDL cholesterol with low LDL cholesterol yielded hazard ratios of 1.18 for all-cause mortality and 1.78 for myocardial infarction. Discordant high apoB with low non-HDL cholesterol yielded a hazard ratio of 1.21 for all-cause mortality and 0.93 for myocardial infarction. Dual discordant high apoB and non-HDL cholesterol with low LDL cholesterol showed hazard ratios of 1.23 for all-cause mortality and 1.82 for myocardial infarction.

Hazard Ratios for All-Cause Mortality and Myocardial Infarction in Statin-Treated Patients
Values shown: Hazard Ratio
High ApoB, Low LDL (Mortality)1.21
High ApoB, Low LDL (MI)1.49
High Non-HDL, Low LDL (Mortality)1.18
High Non-HDL, Low LDL (MI)1.78
High ApoB, Low Non-HDL (Mortality)1.21
High ApoB, Low Non-HDL (MI)0.93
High ApoB & Non-HDL, Low LDL (Mortality)1.23
High ApoB & Non-HDL, Low LDL (MI)1.82

Hazard ratios for all-cause mortality and myocardial infarction based on different discordant lipid profiles in statin-treated patients.

What it means

In statin-treated patients, elevated apoB and non-HDL cholesterol, but not LDL cholesterol, are associated with residual risk of all-cause mortality and myocardial infarction. ApoB is a more accurate marker of all-cause mortality risk than LDL cholesterol or non-HDL cholesterol, and a more accurate marker of myocardial infarction risk than LDL cholesterol.

Limitations

The abstract does not explicitly state any limitations of the study.

Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

Large Mendelian randomization studies, prospective cohorts and meta-analyses — in one pooling of 233,455 people apoB was the strongest lipid risk marker, about 12% better than LDL-cholesterol — indicate that apoB is the predominant lipid trait driving atherosclerotic cardiovascular disease, and that the particle…
