New ACC Guidance on Obesity and Cardiovascular Disease: What Every NP Needs to Know If you're a nurse practitioner in primary care, family practice, or cardiology, you already know that the obesity conversation has fundamentally changed. We're no longer in the era of "eat less, move more" as the sole clinical recommendation. The American College of Cardiology dropped two major guidance documents in August 2025 that every NP managing cardiovascular risk needs to have on their radar — and if you missed them, consider this your clinical catch-up. Let's break down what matters for your practice. Two Documents, One Clear Message The ACC released a Concise Clinical Guidance (CCG) on the medical management of obesity and a Scientific Statement focused specifically on treating obesity in adults with heart failure. Both documents signal a seismic shift in how we should be thinking about weight management as a core component of cardiovascular care — not a side conv...

  Cardiac Biomarkers: Troponin Trends, BNP Pitfalls, and the Chronic Elevation Problem High-sensitivity troponin changed everything. BNP is falsely low in obesity. And a single troponin is almost never enough. Troponin: The Myocardial Injury Marker High-Sensitivity Troponin (hs-cTn) High-sensitivity troponin assays detect far lower concentrations than older assays, enabling faster rule-out of MI but also detecting chronic low-level myocardial injury that was previously invisible. This has created a new problem:  chronic troponin elevation without acute MI . The Trend Is Everything A single troponin value is not diagnostic.  Acute MI shows a rise-and-fall pattern —troponin increases >20% from baseline over 3–6 hours. Chronic elevations (stable, flat values on serial testing) indicate non-ACS myocardial stress. Always order serial troponins at 0 and 3 hours (some protocols use 0 and 1 hour for rapid rule-out with hs-cTn). A flat troponin at two time points effectively ru...
