LP-Little A and Cardiovascular Health: Impact, Measurement, and Management
TLDR LP-Little A, a genetically inherited trait, plays a significant role in cardiovascular health, with about 20% of the world population having elevated levels. Challenges in accurately measuring LPA are being addressed by moving towards nanomoles per liter measurement, with potential therapies like PCSK9 inhibitors and antisense oligonucleotides showing promise in reducing LPA levels for better heart health.
Timestamped Summary
00:00
The episode focuses on LP-LITLA, a genetically inherited trait that confers a high risk of ASCVD, with discussions on its impact, measurement, and management, as well as current and potential therapies.
07:12
Elevated levels of lipoprotein little a (LPA) are present in about 20% of the world population, with varying levels based on ethnicity, and research on LPA has evolved over time due to challenges in accurate measurement.
14:43
Challenges in accurately measuring lipoprotein little a (LPA) are being addressed by moving towards LPA measurement in nanomoles per liter, which provides a more accurate representation of LPA particles in circulation.
22:22
LP-Little A cholesterol content assays are becoming less common as the field moves towards more accurate measurements of LPA particles in circulation, emphasizing the importance of measuring LPA in nanomoles per liter for better risk estimation.
29:54
Statins may not effectively lower LP little a levels, and while there may be a small increase in LP little a when someone is put on a statin, it is still beneficial to use statins, especially in patients with high LP little a levels.
38:06
Variations in the LPA gene, particularly in cringle four type two, impact the isoform size and interactions with ApoA and ApoB, potentially influencing the pathophysiology of heart disease.
46:16
LPA levels can impact the progression of aortic valve stenosis, with high LPA potentially leading to more rapid progression, especially in younger patients.
53:52
LPA levels should be measured early in life, as they can remain elevated from childhood and potentially impact cardiovascular health in adulthood.
01:01:19
Niacin therapy may reduce Lp(a) levels and improve other lipid markers, but evidence from large cardiovascular outcome studies does not support its use due to lack of cardiovascular benefits and potential side effects.
01:08:29
Large cardiovascular outcome studies have shown that the reduction in ApoB lipoproteins, rather than HDL levels, is crucial in decreasing cardiovascular disease risk.
01:15:47
Managing high LPA levels involves focusing on LDL, LPA, lifestyle factors, and other cardiovascular risk factors to reduce the risk of events.
01:23:21
LPA plays a role in both the initiation and progression of atherosclerosis, contributing to inflammation and plaque formation in patients with high LPA levels.
01:31:20
LPA is strongly associated with aortic stenosis, myocardial infarction, peripheral vascular disease, ischemic cerebral strokes, and chronic kidney disease.
01:39:32
Mutations causing very high cholesterol levels are linked to accelerated ASCVD, with PCSK9 influencing LDL receptor density through various mechanisms.
01:47:29
The effectiveness of PCSK9 inhibitors in lowering LP Little A levels varies among patients, with an average reduction of about 25-30%, but significant variability remains.
01:55:27
Antisense oligonucleotides against LPA show promise in significantly reducing LPA levels, with a potential for 80% reduction, offering hope for preventing heart attacks and improving cardiovascular outcomes.
02:03:08
The potential approval of an antisense oligonucleotide for LPA could have a significant impact on human health, especially when combined with the use of PCSK9 inhibitors, urging listeners to check their LP little a levels and manage cardiovascular risk factors.
