Emergency Medicine Cardiovascular Risk Assessment for Lipid Disorders Trial

Overview

Emergency Medicine Cardiovascular Risk Assessment for Lipid Disorders (EMERALD) is a protocolized intervention based on American College of Cardiology/American Heart Association and US Preventive Services Task Force guidelines designed to initiate preventive cardiovascular care for emergency department patients being evaluated for acute coronary syndrome. The overarching goals of this proposal are to (1) determine the efficacy of EMERALD at lowering low-density lipoprotein cholesterol (LDL-C) and non high-density lipoprotein cholesterol (non-HDL-C) among at-risk Emergency Department (ED) patients who are not already receiving guideline-directed outpatient preventive care and (2) inform our understanding of patient adherence and determinants of implementation for ED-based cardiovascular disease prevention strategies.

EMERALD involves (1) ordering an ED lipid panel, (2) calculating 10-year atherosclerotic cardiovascular disease (ASCVD) risk, (3) prescribing a moderate- or high-intensity statin, (4) providing healthy lifestyle counseling, and (5) bridging patients to ongoing outpatient preventive care (primary care or cardiology, depending on risk level). We hypothesize that EMERALD will be associated with lower LDL-C and non-HDL-C at 30- and 180-days vs. usual care. The primary outcome will be percent change in LDL-C at 30-days. Secondary outcomes include percent change in LDL-C at 180-days and non-HDL-C at 30- and 180-days. We will randomize 130 ED patients with possible acute coronary syndrome 1:1 to EMERALD or usual care, which will provide 90% power with a two-sided alpha of 0.05 to demonstrate a 10% difference in percent change in LDL-C at 30-days between arms.
