Remnant cholesterol, LDL cholesterol, and apoB absolute mass changes explain results of the PROMINENT trial.

BACKGROUND AND AIMS: The PROMINENT trial, a cardiovascular outcome trial of the triglyceride- and remnant cholesterol-lowering agent pemafibrate, has shown neutral results despite reduction in plasma triglycerides and remnant cholesterol. We tested the hypothesis that absolute mass changes in remnant cholesterol, LDL cholesterol, and apolipoprotein B explain the results of the PROMINENT trial. METHODS: Among 108,431 individuals from the Copenhagen General Population Study (CGPS), those who met the key inclusion criteria of the PROMINENT trial were analyzed to mimic the trial design. Endpoint atherosclerotic cardiovascular disease (ASCVD) was cardiovascular death, myocardial infarction, ischemic stroke, and coronary revascularization as defined in PROMINENT. RESULTS: In the PROMINENT trial, treatment with pemafibrate resulted in -7 mg/dL (-0.18 mmol/L; -18 %) change in remnant cholesterol, +10 mg/dL (+0.26 mmol/L; +12 %) LDL cholesterol, and +5 mg/dL (+0.05 g/L; +5 %) apolipoprotein B. In the CGPS mimicking PROMINENT, the estimated hazard ratios for ASCVD were 0.97 (95 % confidence interval: 0.94-0.99) for a -7 mg/dL (-0.18 mmol/L) change in remnant cholesterol, 1.04 (1.01-1.07) for a +10 mg/dL (+0.26 mmol/L) change in LDL cholesterol, and 1.02 (1.01-1.03) for a +5 mg/dL (+0.05 g/L) change in apolipoprotein B. When combining absolute changes in remnant cholesterol, LDL cholesterol, and apolipoprotein B, the estimated hazard ratio for ASCVD was 1.05 (0.96-1.14) in the CGPS mimicking PROMINENT compared to 1.03 (0.91-1.15) in the PROMINENT trial. CONCLUSIONS: Absolute mass changes in remnant cholesterol, LDL cholesterol, and apolipoprotein B can explain results of the PROMINENT trial. The 3 mg/dL (0.08 mmol/L) higher total atherogenic cholesterol together with 5 mg/dL (0.05 g/L) higher apolipoprotein B seem to explain the trend toward more ASCVD in the pemafibrate arm.

Dual elevated remnant cholesterol and C-reactive protein in myocardial infarction, atherosclerotic cardiovascular disease, and mortality.

BACKGROUND AND AIMS: Elevated remnant cholesterol and low-grade inflammation each cause atherosclerotic cardiovascular disease (ASCVD); however, it is unknown whether joint elevation of both factors confers the highest risk. We tested the hypothesis that dual elevated remnant cholesterol and low-grade inflammation marked by elevated C-reactive protein is associated with the highest risk of myocardial infarction, ASCVD, and all-cause mortality. METHODS: The Copenhagen General Population Study randomly recruited white Danish individuals aged 20-100 years in 2003-2015 and followed them for a median 9.5 years. ASCVD was cardiovascular mortality, myocardial infarction, stroke, and coronary revascularization. RESULTS: In 103,221 individuals, we observed 2,454 (2.4%) myocardial infarctions, 5,437 (5.3%) ASCVD events, and 10,521 (10.2%) deaths. The hazard ratios increased with each of stepwise higher remnant cholesterol and stepwise higher C-reactive protein. In individuals with the highest tertile of both remnant cholesterol and C-reactive protein compared to individuals with the lowest tertile of both, the multivariable adjusted hazard ratios were 2.2 (95%CI:1.9-2.7) for myocardial infarction, 1.9 (1.7-2.2) for ASCVD, and 1.4 (1.3-1.5) for all-cause mortality. Corresponding values for only the highest tertile of remnant cholesterol were 1.6 (1.5-1.8), 1.4 (1.3-1.5), and 1.1 (1.0-1.1), and those for only the highest tertile of C-reactive protein were 1.7 (1.5-1.8), 1.6 (1.5-1.7), and 1.3 (1.3-1.4), respectively. There was no statistical evidence for interaction between elevated remnant cholesterol and elevated C-reactive protein on risk of myocardial infarction (p = 0.10), ASCVD (p = 0.40), or all-cause mortality (p = 0.74). CONCLUSIONS: Dual elevated remnant cholesterol and C-reactive protein confers the highest risk of myocardial infarction, ASCVD, and all-cause mortality, that is, compared to either of these two factors individually.

Dislipidemia aterogénica en Latino América: prevalencia, causas y tratamiento / Atherogenic dislipidemia in Latin America: prevalence, causes and treatment

En las guías clínicas actuales, la dislipidemia aterogénica (DA) es una entidad escasamente atendida. Debido a las frecuentes alteraciones en los lípidos asociados a la DA en Latino América (LA), se organizó un grupo de expertos que se ha denominado Academia Latino Americana para el estudio de los Lípidos (ALALIP) para generar un documento con análisis de su prevalencia y ofrecer recomendaciones prácticas. Se utilizó la metodología Delphi modificada, con revisión comprensiva de la literatura con énfasis en aquellas publicaciones con implicaciones para LA. Subsecuentemente, se desarrollaron preguntas claves para ser discutidas. En LA no existe un estudio global sobre los factores de riesgo que representan a la totalidad de la población. El análisis sistemático de las encuestas nacionales de salud y de los estudios sistemáticos de cohorte muestran consistentemente una alta prevalencia de las anormalidades lipídicas que definen la DA. La concentración baja del colesterol unido a las lipoproteínas de alta densidad (C-HDL) varía entre 34,1% a 53,3% y la de triglicéridos (TG) elevados del 25,5% al 31,2%, con mayor prevalencia entre los hombres. Múltiples causas se han reconocidos, como alta ingesta de alimentos de mayor densidad calórica, contenido de colesterol, grasas trans, sedentarismo y cambios epigenéticos. La DA bien puede ser tratada con los cambios terapéuticos del estilo de vida (CTEV) con incremento en la actividad física, ejercicio regular y dieta baja en carbohidratos y alta en ácidos grasos poliinsaturados, tales como los ácidos grasos omega-3 como intervención primaria. De ser necesario, esta estrategia sera suplementada con terapia farmacológica como la monoterapia con estatinas o la combinación de fibratos/ácidos grasos omega-3. Las anormalidades lipídicas que definen la DA tienen una elevada prevalencia en LA; su interacción con un estilo de vida no saludable, herencia y cambios epigenéticos están ligados a sus posibles causas. La DA es una causa importante de riesgo cardiovascular residual (RCVR) que debe ser diagnosticada y tratada. Es importante y necesario diseñar un estudio global de factores de riesgo en LA para conocer la real prevalencia de la DA.

In the current clinical guidelines, atherogenic dyslipidemia (AD) is a poorly recognized entity. Due to the frequent lipid alterations associated with AD in Latin America (LA), we organized a group of experts named Latin American Academy for the study of Lipids (ALALIP), to generate a document for analyzing its prevalence and to offer practical recommendations. Using the Delphi methodology, we conducted a comprehensive literature review, with emphasis on those publications with implications for LA. Subsequently we developed key questions to be discussed. In LA there is no a global study on risk factors that represent the entire population. The systematic analysis of national health surveys and regional cohort studies showed a consistent high prevalence of the lipid abnormalities that define AD. Low high density lipoprotein cholesterol (HDL-C) ranges from 34.1% to 53.3% and elevated triglycerides (TG) from 25.5% to 31.2%, more prevalent in men. There are multiple causes: high consumption of foods with a high caloric density, cholesterol and trans fats, sedentary lifestyle and epigenetic changes. AD must be well treated with therapeutic changes in lifestyle with increased in physical activities, regular exercise and a diet with a low proportion of carbohydrates y rich in poliunsatured fatty acid, such as omega-3 fatty acid as primary intervention. If needed, this strategie must be supplemented with pharmacological therapies such as monotherapy with statins or a combination of fibrates plus omega-3.fatty acid. Lipid abnormalities that define AD have a high prevalence in LA; the interaction between non-healthy lifestyle, inheritance and epigenetic changes, possibly are its cause. AD is an important cause of cardiovascular residual risk (CVRR), that must be diagnosed and treated. It is important and neccesary to design a global study of risk factors in LA to know the true prevalence of AD.
