  • 'Remnant Cholesterol' As Stand-Alone Risk for Heart Attack and Stroke 8 September 2021
    Study suggests 'remnant cholesterol' as stand-alone risk for heart attack and stroke 8 September 2021 Remnant cholesterol levels are basically calculated as the total cholesterol amount minus the LDL and high-density lipoprotein cholesterol (HDL, the so- called "good cholesterol") counts. In their study, first published July 19, 2021, in the European Heart Journal, the researchers suggest that for people with relatively low levels of LDL cholesterol, a measured RC level greater than 24 micrograms per deciliter (24 millionths of a gram in a little more than a quart) of blood have a 40–50% higher risk for major heart disease or stroke.

However, detailed insight into the effects of CETP on lipoprotein subclasses is lacking. Therefore, we used a Mendelian randomization approach based on a genetic score for serum CETP concentration (rs247616, rs12720922 and rs1968905) to estimate causal effects per unit (µg/mL) increase in 1234567890();,: 1234567890();,: CETP on 159 standardized metabolic biomarkers, primarily lipoprotein subclasses. Metabolic biomarkers were measured by nuclear magnetic resonance (NMR) in 5672 participants of the Netherlands Epidemiology of Obesity (NEO) study. Higher CETP concentrations were associated with less large HDL (largest effect XL-HDL-C, P = 6×10–22) and more small VLDL components (largest effect S-VLDL cholesteryl esters, P = 6×10–6). No causal effects were observed with LDL subclasses.

Impaired LPL activity leads to the accumulation of chylomicrons and very low-density lipoproteins (VLDL) in plasma, resulting in hypertriglyceridemia. While low-density lipoprotein cholesterol (LDL-C) is recognized as a primary risk factor for atherosclerosis, hypertriglyceridemia has been shown to be an independent risk factor for cardiovascular disease (CVD) and a residual risk factor in atherosclerosis development. In this review, we focus on the lipolysis machinery and discuss the potential role of triglycerides, remnant particles, and lipolysis mediators in the onset and progression of atherosclerotic cardiovascular disease (ASCVD). This review details a number of important factors involved in the maturation and transportation of LPL to the capillaries, where the triglycerides are hydrolyzed, generating remnant lipoproteins. Moreover, LPL and other factors involved in intravascular lipolysis are also reported to impact the clearance of remnant lipoproteins from plasma and promote lipoprotein retention in Citation: Kumari, A.; Kristensen, capillaries. Apolipoproteins (Apo) and angiopoietin-like proteins (ANGPTLs) play a crucial role in K.K.; Ploug, M.; Winther, A.-M.L.

(s.e. ¼ 0.27 per minor allele (P-value ¼ 8.0 Â 10 À 8)) discovered in 3,202 individuals with low read-depth, whole-genome sequence. We replicate this in 12,831 participants from five additional samples of Northern and Southern European origin ( À 1.0 s.d. (s.e. ¼ 0.173), P-value ¼ 7.32 Â 10 À 9). This is consistent with an effect between 0.5 and 1.5 mmol l À 1 dependent on population.
