Summary
This summary is machine-generated.High Lipoprotein(a) [Lp(a)] levels are linked to the presence and new onset of aortic valve calcium (AVC). However, Lp(a) does not appear to influence AVC progression, suggesting early intervention is key.
Area Of Science
- Cardiovascular Medicine
- Biochemistry
- Radiology
Background
- Lipoprotein(a) [Lp(a)] is implicated in aortic valve disease pathogenesis.
- The association between Lp(a) and aortic valve calcium (AVC) incidence and progression remains understudied.
Purpose Of The Study
- To investigate the relationship between high serum Lp(a) levels and the incidence and progression of AVC.
Main Methods
- Utilized data from the Rotterdam Study (922 participants).
- Assessed Lp(a) levels and performed cardiac CT imaging at baseline and after a median 14-year follow-up.
- Employed logistic and linear regression analyses, adjusting for multiple covariates.
Main Results
- Lp(a) was independently associated with baseline AVC (OR 1.43) and new-onset AVC (OR 1.30).
- No significant association was found between Lp(a) and AVC progression (β: -71 AU).
- Baseline AVC score was the primary predictor of AVC progression (P < 0.001).
Conclusions
- Lp(a) is strongly associated with the presence and new onset of AVC.
- Lp(a) does not appear to influence the progression of existing AVC.
- Lp(a)-lowering therapies may be most beneficial in the early stages of aortic valve disease, before significant calcification occurs.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
Overview
In response to tissue injury and infection, mast cells initiate inflammation. Mast cells release chemicals that increase the permeability of adjacent blood capillaries and attract additional immune cells to the wound or site of infection. Neutrophils are phagocytic leukocytes that exit the bloodstream and engulf invading microbes. Blood clotting platelets seal the wound and fibers create a scaffold for wound healing. Macrophages engulf aging neutrophils to end the acute inflammatory...
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
