The multivariable hazard ratios comparing the extreme quartiles of plasma C:16, C22:0, C24:0, and C24:1 concentrations were 2.39 (1.49–3.83, p < 0.001), 1.91 (1.21–3.01, p = 0.003), 1.97 (1.21–3.01, p = 0.004), and 1.73 (1.09–2.74, p = 0.011), respectively. |

Longitudinal study; 3 large cohort studies: 3789 patients (62 years old; 72% male, LDL-cholesterol 2.9 mmol/l, triglycerides 1.5 mmol/l, statin use 72.6%) from the Western Norway Coronary Angiography Cohort (WECAC); 5991 patients (65 years old; 83% male, LDL-cholesterol 3.9 mmol/l, triglycerides 1.6 mmol/l, statin use 49.9%) from the Long-Term Intervention with Pravastatin in Ischaemic Disease (LIPID) study; and 1023 patients (62 years old; 84% male, LDL-cholesterol 3 mmol/l, triglycerides 1.6 mmol/l, statin use 75.6%) from the Langzeiterfolge der Kardiologischen Anschlussheilbehandlung (KAROLA) study. Follow-up: 6 years |

IAge, sex, treatment with statins (WECAC, KAROLA), diabetes mellitus, hypertension, current smoking habit, previous MI, previous stroke, stratified according to vitamin B intervention (WECAC) and treatment group (LIPID). |
A simple risk score, based on ceramides and phosphatidylcholines with the best prognostic characteristics, was developed by the WECAC study and validated in the other 2 cohorts. This score was highly significant for predicting mortality due to CVD (multi-adjusted hazard ratios [95% CI] per standard deviation were 1.44 [1.28–1.63] at the WECAC, 1.47 [1.34–1.61] at the LIPID study, and 1.69 [1.31– 2.17] at the KAROLA study). Moreover, a combination of the risk score with high-sensitivity troponin T increased hazard ratios to 1.63 (1.44–1.85) and 2.04 (1.57–2.64) in the WECAC and KAROLA cohorts, respectively. |
