Role of Polyunsaturated Fat in Modifying Cardiovascular Risk Associated With Family History of Cardiovascular Disease: Pooled De Novo Results From 15 Observational Studies

Circulation, Ahead of Print. BACKGROUND:It is unknown whether dietary intake of polyunsaturated fatty acids (PUFA) modifies the cardiovascular disease (CVD) risk associated with a family history of CVD. We assessed interactions between biomarkers of low PUFA intake and a family history in relation to long-term CVD risk in a large consortium.METHODS:Blood and tissue PUFA data from 40 885 CVD-free adults were assessed. PUFA levels ≤25th percentile were considered to reflect low intake of linoleic, alpha-linolenic, and eicosapentaenoic/docosahexaenoic acids (EPA/DHA). Family history was defined as having ≥1 first-degree relative who experienced a CVD event. Relative risks with 95% CI of CVD were estimated using Cox regression and meta-analyzed. Interactions were assessed by analyzing product terms and calculating relative excess risk due to interaction.RESULTS:After multivariable adjustments, a significant interaction between low EPA/DHA and family history was observed (product term pooled RR, 1.09 [95% CI, 1.02–1.16];P=0.01). The pooled relative risk of CVD associated with the combined exposure to low EPA/DHA, and family history was 1.41 (95% CI, 1.30–1.54), whereas it was 1.25 (95% CI, 1.16–1.33) for family history alone and 1.06 (95% CI, 0.98–1.14) for EPA/DHA alone, compared with those with neither exposure. The relative excess risk due to interaction results indicated no interactions.CONCLUSIONS:A significant interaction between biomarkers of low EPA/DHA intake, but not the other PUFA, and a family history was observed. This novel finding might suggest a need to emphasize the benefit of consuming oily fish for individuals with a family history of CVD.

AGA Clinical Practice Update on the Use of Vasoactive Drugs and Intravenous Albumin in Cirrhosis: Expert Review

Cirrhosis is a major cause of morbidity and mortality in the United States and worldwide. It consists of compensated, decompensated, and further decompensated stages; median survival is more than 15 years, 2 years, and 9 months for each stage, respectively. With each stage, there is progressive worsening of portal hypertension and the vasodilatory–hyperdynamic circulatory state, resulting in a progressive decrease in effective arterial blood volume and renal perfusion. Vasoconstrictors reduce portal pressure via splanchnic vasoconstriction and are used in the management of variceal hemorrhage.

Abstract 13948: Real World De-Escalation Practices in Genotype Guided P2Y12 Inhibitor Therapy and Pharmacoeconomic Implications

Circulation, Volume 148, Issue Suppl_1, Page A13948-A13948, November 6, 2023. Background:Tailored P2Y12 inhibitor therapy is gaining popularity and is described as a method to balance safe and effective prescribing of clopidogrel. Based on previous work, 28% of our patients with CYP2C19 genotyping do not metabolize clopidogrel effectively (intermediate or poor metabolizers).Aim:We aim to describe the economic impact of a guided P2Y12 inhibitor strategy and the practice of escalation (clopidogrel to ticagrelor/prasugrel) and de-escalation (ticagrelor/prasugrel to clopidogrel) practices at a single health system. We hypothesize a guided approach is economically feasible vs. a universal ticagrelor or prasugrel approach. We also aim to determine how quickly clinicians escalate or de-escalate in response to CYP2C19 results.Methods:3-year (2020-2022) data was collected from our EMR. Annually an average of 950 patients received CYP2C19 testing to guide P2Y12 inhibitor therapy (n=2799), and an average of 316 patients were either escalated or de-escalated (n=949). Of the 2799 patients, clopidogrel was most often the initial P2Y12 inhibitor (n=2240), followed by ticagrelor (n=525), and prasugrel (n=34). We estimated overall medication and CYP2C19 testing costs over the course of an average year (Figure 1) based on the assumption that over the course of 1-year patients would begin on 30 days of either ticagrelor, prasugrel, or clopidogrel and escalate/de-escalate therapy thereafter as guided by testing.Results:The time to escalation was similar if the CYP2C19 result was ordered before or after the first order for P2Y12 inhibitor therapy, median of 6.2 and 6.5 days respectively (p = .07). There was a difference in time to de-escalation based on time of CYP2C19 testing in comparison to medication ordering with a median time of 32.1 and 8 days when testing was ordered before initiation and after, respectively (p
