Background
Remnant cholesterol has been identified as one of leading lipid values associated with the incidence of coronary heart disease. There is scarce evidence on its distribution and prognostic value in acute coronary syndrome (ACS) patients.
Methods and results
We included all consecutive patients admitted for ACS in two different centres. Remnant cholesterol was calculated by the equation: total cholesterol minus LDL cholesterol minus HDL cholesterol, and values ≥30 were considered high. Among the 7479 patients, median remnant cholesterol level was 28 mg/dL (21–39), and 3429 (45.85%) patients had levels ≥30 mg/dL. Age (r: −0.29) and body mass index (r: 0.44) were the variables more strongly correlated. At any given age, patients with overweigh or obesity had higher levels. In-hospital mortality was 3.75% (280 patients). Remnant cholesterol was not associated to higher in-hospital mortality risk (odds ratio: 0.89; P = 0.21). After discharge (median follow-up of 57 months), an independent and linear risk of all-cause mortality and heart failure (HF) associated to cholesterol remnant levels was observed. Remnant cholesterol levels >60 mg/dL were associated to higher risk of mortality [hazard ratio (HR): 1.49 95% CI 1.08–2.06; P = 0.016], cardiovascular mortality (HR: 1.49 95% CI 1.08–2.06; P = 0.016), and HF re-admission (sub-HR: 1.55 95% CI 1.14–2.11; P = 0.005).
Conclusions
Elevated remnant cholesterol is highly prevalent in patients admitted for ACS and is inversely correlated with age and positively with body mass index. Remnant cholesterol levels were not associated to higher in-hospital mortality risk, but they were associated with higher long-term risk of mortality and HF.

Lay Summary
Elevated remnant cholesterol is highly prevalent in patients admitted for ACS and is related to body mass index and negatively with age. Remnant cholesterol it is not associated to higher in-hospital mortality risk, but it confers higher long-term risk of mortality and heart failure. |
