Key Points<\/p>\n
<\/p>\n
More than 75% of patients with ACS are na\u00efve to LLT on presentation, and only 25% are able to achieve guidelines LDL-C goals within 3 months post-ACS when a single LLT agent is used.\u00a0 Most patients require combination therapy to get to goal, and getting to goal early and sustaining this improvement over time is associated with improved cardiovascular outcomes.\u00a0 Whether a DSS can shorten the time to combination therapy and reduce the delay to getting to goal compared to usual care is uncertain.<\/p>\n
On November 17th<\/sup> \u00a02024, the results of \u201cOptimiZation Of Lipid Lowering Therapies Using A Decision Support System In Patients With Acute Coronary Syndrome (ZODIAC): A Randomized Controlled Trial\u201d were presented at AHA Scientific Sessions 2024.<\/em> The purpose of this study was to determine if a DSS providing estimates of residual CVD risk and the benefits of various LLTs based on the 2019 European Society Guidelines would lead to earlier optimization of lipid therapy and lipid levels compared to SoC.<\/p>\n This interventional, parallel-assignment, statistician-blinded, cluster-randomized controlled trial included 1140 adults from 42 sites in the UK, Italy, and Spain who were less than 80 years old and hospitalized for less than 72 hours post-ACS.\u00a0 They were assigned in a 1:1 fashion at each site to the DSS or SOC.\u00a0 The primary endpoint was the proportion of patients who received combination therapy, escalated monotherapy, or escalated combination therapy within 16 weeks of ACS.<\/p>\n The median age was 62 years, 22% were female, and the mean LDL-C was 116 mg\/dL; 67% were LLT na\u00efve on presentation. Overall, 59.7% of patients in the SoC arm and 70.7% of patients in the DSS arm achieved the primary endpoint, a difference that did not reach statistical significance (RR 1.15 [95% CI 0.93-1.41]).\u00a0 There was also no significant difference in the primary endpoint among any of the prespecified subgroups, including a prior history of ASCD or LLT exposure. There was an overall shift in prescribing behavior towards more potent combination therapies in the DSS arm, and more participants received their first LLT escalation prior to discharge in the DSS arm.<\/p>\n One limitation of this study was power to detect clinically significant differences. Additionally, awareness of ZODIAC aims may have biased clinician decisions in the control arm, as the SOC pathways outperformed historical data the authors used for their power calculation.<\/p>\n Kausik K. Ray MD, FAHA, FMedSci, Professor of Public Health, Imperial College of London, concluded: \u201cAvailability of a DSS system did not significantly improve use of combination therapies and intensification of LLT regimens versus current care pathways. Favorable trends were seen in the DSS arm and this may have value in other settings where the implementation is slower such as primary care \u2013 this requires further evaluation.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":" Key Points Maximizing lipid lowering therapy (LLTs) to optimize residual cardiovascular disease (CVD) risk after acute coronary syndrome (ACS) is usually a stepwise approach that can take months or years for many patients.
