August marks a pivotal moment in preventive cardiology — a new guideline settling into practice, a major anti-inflammatory trial disappointment, a breakthrough therapy for a neglected condition, and one of cardiology's largest congresses about to unfold. Here's everything worth knowing. ─── 1. The 2026 Dyslipidemia Guideline Is Here — And It Changes Everything The ACC/AHA/Multisociety Guideline on the Management of Dyslipidemia dropped in March 2026, and August is when clinicians are actually starting to apply it. The core shift: treat earlier, target lower. The guideline introduces the "CPR" model for every patient encounter: • *C*alculate — Use the new PREVENT score to get 10-year and 30-year risk estimates • *P*ersonalize — Factor in risk enhancers the calculator doesn't capture: family history, Lp(a), hsCRP, reproductive history, chronic inflammatory conditions • *R*eclassify — Use the CAC score to reclassify and potentially escalate or de-escalate therapy The LDL-C targets are concrete now — not just percent reductions: | Risk Level | LDL-C Goal | Non-HDL-C Goal | | --------------------------------- | ---------- | -------------- | | High (≥10% 10-yr PREVENT) | <70 mg/dL | <100 mg/dL | | Borderline / Intermediate (3–10%) | <100 mg/dL | <130 mg/dL | Lp(a) gets its first-ever universal screening recommendation from ACC/AHA — measure it at least once in every adult. This is a major upgrade from prior guidance. Values >125 nmol/L carry ~1.4× ASCVD risk; >250 nmol/L carry ≥2× risk. One blood test. Lifetime implications forcascade screening. ─── 2. ZEUS Trial: The Anti-Inflammatory Hypothesis Takes a Hit Novo Nordisk's ziltivekimab — a monoclonal antibody targeting interleukin-6 (IL-6), the inflammation cytokine thought to be a central driver of residual cardiovascular risk — failed to reduce major adverse cardiovascular events in the phase 3 ZEUS trial. Despite ziltivekimab demonstrating robust biological activity — significant drops in IL-6 and CRP — the primary MACE endpoint (MI, stroke, CV death) was not met. HR 0.99. Neutral.
