HDL ldl cholesterol (high-density lipoprotein ldl cholesterol), or “good ldl cholesterol,” is related to a decreased threat of heart problems because it transports ldl cholesterol deposited within the arteries to the liver to be eradicated. This contrasts with the so-called “dangerous ldl cholesterol,” LDL (low-density lipoprotein ldl cholesterol), which causes ldl cholesterol to build up within the arteries and will increase cardiovascular threat. Though medicine that decrease LDL ldl cholesterol cut back cardiovascular threat, those who increase good ldl cholesterol haven’t confirmed efficient in decreasing the danger of coronary heart illness. This paradox has referred to as into query the connection between good ldl cholesterol and cardiovascular threat, and researchers are actually learning the traits of those HDL or good ldl cholesterol particles.
A examine led by the Hospital del Mar Medical Analysis Institute (IMIM), revealed within the journal Metabolism, Medical and Experimental, has now demonstrated that not all good ldl cholesterol is wholesome. Researchers from the CIBER on Cardiovascular Illnesses (CIBERCV), the CIBER on Weight problems and Diet (CIBEROBN), and the CIBER on Epidemiology and Public Well being (CIBERESP), in addition to others from Hospital Clínic-IDIBAPS, IDIBELL, the Hospital de la Santa Creu i Sant Pau Analysis Institute, and the Hospital Clínico Universitario in Zaragoza additionally took half on this examine.
Within the work, the researchers analyzed genetic traits that decide the scale of excellent ldl cholesterol particles, after which studied their relationship with the danger of myocardial infarction. The conclusion is that genetic traits linked to the era of huge good ldl cholesterol particles are instantly related to the next threat of coronary heart assault, whereas options linked to small good ldl cholesterol particles are associated to a decrease threat of coronary heart assault.
“There’s a constructive causal relationship between the scale of HDL ldl cholesterol particles and the danger of coronary heart assault, so though we have now to extend the degrees of excellent ldl cholesterol within the blood, they need to at all times be small particles,” explains the examine’s principal investigator, Dr. Robert Elosua, a researcher on the Hospital del Mar-IMIM, CIBERCV, and the College of Vic-Central College of Catalonia (UVic-UCC).
The great ldl cholesterol particles are simpler in transferring ldl cholesterol to the liver in order that it may be eradicated. “If we have to do one thing in relation to HDL, it’s to extend the variety of small particles, that are those who adequately carry out the perform of eliminating ldl cholesterol, those who actually transfer it to the liver for elimination, and don’t enable it to build up within the arteries and trigger heart problems,” says Dr. Álvaro Hernáez, a IDIBAPS and CIBEROBN researcher.
At present, there aren’t any medicine that enhance good levels of cholesterol and cut back the danger of heart problems. “This examine highlights new and potential therapeutic targets within the discipline of cardiovascular ailments, together with a number of genes associated to the qualitative points of HDL particles, which can contribute to cardiovascular prevention,” concludes Dr. Albert Prats, a researcher within the Epidemiology and Cardiovascular Genetics Analysis Group on the Hospital del Mar-IMIM and first writer of the examine.
