Background: Implementation of semaglutide weight loss therapy has been challenging due to drug supply and cost, underscoring a need to identify those who derive the greatest absolute benefit.
Objectives: Allocation of semaglutide was modeled according to coronary artery calcium (CAC) among individuals without diabetes or established atherosclerotic cardiovascular disease (CVD).
Methods: In this analysis, 3,129 participants in the MESA (Multi-Ethnic Study of Atherosclerosis) without diabetes or clinical CVD met body mass index criteria for semaglutide and underwent CAC scoring on noncontrast cardiac computed tomography.
Aims: To assess the association of traditional risk factor burden and Life's Simple 7 (LS7) score with incident atherosclerotic cardiovascular disease (ASCVD) across Lp(a) levels.
Methods: There were 6,676 participants without clinical ASCVD from the Multi-Ethnic Study of Atherosclerosis who underwent Lp(a) testing and were followed for incident ASCVD events (coronary heart disease and stroke). Low, intermediate, and elevated Lp(a) were defined as <30, 30-49, and >50 mg/dL, respectively.
Background: Oxidized phospholipids (OxPLs) are carried by apolipoprotein B-100-containing lipoproteins (OxPL-apoB) including lipoprotein(a) (Lp[a]). Both OxPL-apoB and Lp(a) have been associated with calcific aortic valve disease (CAVD).
Objectives: This study aimed to evaluate the associations between OxPL-apoB, Lp(a) and the prevalence, incidence, and progression of CAVD.
Article Synopsis
- The study examines the relationship between polygenic scores for coronary heart disease (CHD) and coronary artery calcium (CAC) in adults aged 75 and older, suggesting that genetic factors may influence arterial aging beyond traditional risk factors.
- Researchers analyzed data from 1,865 participants, finding that higher polygenic CHD risk scores were associated with significantly lower odds of having no CAC and much higher odds of having high CAC levels.
- Each standard deviation increase in the polygenic risk score corresponded to a 78% increase in CAC scores, indicating a strong link between genetic predisposition and arterial health in older adults.
Purpose Of Review: To review the current evidence and highlight future strategies regarding consideration of coronary artery calcium (CAC) density in cardiovascular disease (CVD) risk stratification.
Recent Findings: Expressed as the product of plaque area and a peak calcium density weighting factor, the Agatston method is the gold-standard for measuring CAC on noncontrast cardiac computed tomography. Over the last decade, observational data have suggested that calcium density is inversely associated with CVD events and confers additional prognostic information independent of traditional risk factors and Agatston CAC scores.
