Join CardioNerds for a great discussion about key ACC 2021 Prevention highlights featuring the ADAPTABLE and STRENGTH trials. This episode is produced in collaboration with the American College of Cardiology Prevention of Cardiovascular Disease Council with mentorship from the Council’s Chair Dr. Eugene Yang (University of Washington Medical Center) who provides a message at the end of the episode. First, Dr. Amit Goyal and Council Representative Dr. Mahmoud Al Rifai (FIT, Baylor College of Medicine) discuss the implications of the ADAPTABLE Trial with Dr. Gina Lundberg (Emory University School of Medicine). Then Dr. Tommy Das (FIT, Cleveland Clinic), Dr. Rick Ferraro (FIT, Johns Hopkins) and Council Representative Dr. Anum Saeed (FIT, University of Pittsburgh Medical Center) discuss the results of the STRENGTH trial’s secondary analysis with Dr. Steven Nissen (Cleveland Clinic).

Show notes ADAPTABLE Trial The ADAPTABLE trial is a randomized open label pragmatic trial comparing two doses of aspirin (325 mg vs. 81 mg) for the secondary prevention of cardiovascular disease. The trial employed a range of innovative and low-cost methods to simplify the identification, recruitment, and follow-up of patients. The primary effectiveness outcome was a composite of death from any cause, hospitalization for myocardial infarction, or hospitalization for stroke. The primary safety outcome was hospitalization for major bleeding. A total of 15,076 patients were followed for a median of 26.2 months. The primary effectiveness and safety outcomes were not significantly different between the two groups. Together with Dr. Lundberg we discuss design and methodological issues related to the trial and applicability to clinical practice. ASA 81 mg is as effective as ASA 325 mg for reducing cardiovascular events ASA 325 mg does not cause more bleeding episodes than ASA 81 mg ASA dosing should be based on a clinician-patient risk discussion incorporating patients’ risk profile and their values and preferences Future trials should ensure adequate representation of women and race/ethnic minorities The results of the present trial suggest that either dose of ASA (81 mg or 325 mg) would be adequate to lower patients’ risk of death or atherosclerotic cardiovascular events with similar risk of bleeding. ASA dosing should be based on patient values and preferences and clinician judgement as the effectiveness and safety profile of these two regiments appears to be equivalent on the basis of the present trial. STRENGTH Trial, Secondary Analysis Whether omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) reduce cardiovascular risk has been long debated. Data have largely remained inconclusive with several previous trials, particularly the VITAL and ASCEND, showing no significant cardiovascular benefit DHA and EPA supplementation. However, the REDUCE-IT and the JELIS trials showed cardiovascular benefit with higher dose of purified EPA compared to placebo. Meanwhile, the STRENGTH trial did not show any difference in CVD outcomes in treatment groups using a combined EPA/DHA formulation. In this episode, we discuss a secondary anaylsis from the STRENGTH trial entitled “Association Between Achieved ω-3 Fatty Acid Levels and Major Adverse Cardiovascular Outcomes in Patients With High Cardiovascular Risk” presented at the ACC 2021 addressing the effects of carboxylic acid formulation of EPA/DHA (omega-3 CA) compared with placebo among patients with dyslipidemia and high cardiovascular risk. This analysis showed that there was no added clinical benefit or harm i...
