Oefeningen bij hartfalen — HF-ACTION-protocol

Heart failure (HF) used to be the condition where exercise was forbidden — patients were told to rest, conserve cardiac output, avoid exertion. The 2009 HF-ACTION trial (O'Connor et al., NEJM) reversed that completely. 2,331 patients with reduced ejection fraction were randomised to supervised aerobic exercise + home program vs usual care. Result: better quality of life, fewer hospitalizations, and trend toward reduced mortality. The 2013 AHA heart failure guidelines made exercise a class I recommendation — the strongest evidence tier. Cardiac rehab supervision is strongly recommended for the first 6-12 weeks, especially if ejection fraction is below 35%, NYHA class III, or there's been a recent decompensation. Resistance training has its own evidence: Mandic 2018 showed high-rep low-load resistance training (e.g. 15-20 reps at lower percentages of 1RM) is SAFE in heart failure — counter to the old worry. The critical AVOID: heavy Valsalva-loaded strength + breath-holding, which spikes preload and can precipitate symptoms.

Volya's catalogue carries the foundation: slow-arm-swing-walk and standing-march for the aerobic protocol that owns HF-ACTION's effect, seated-march when standing fatigues (very common), wall-push-up for upper-body strength without Valsalva, supported-glute-bridge for joint-friendly glute work, sit-to-stand for functional strength + the eccentric leg work, diaphragmatic-breathing for autonomic regulation (vagal tone improvement is part of the HF mechanism), scapular-retraction for posture. The AI coach also knows the nutrition side — sodium ≤2 g/day for moderate-severe HF (≤1.5 g if symptomatic), fluid restriction 1.5-2 L/day for NYHA III-IV (cardiologist sets exact target — don't self-restrict), Mediterranean / DASH pattern, daily morning weighing (2-3 lb / 1-1.5 kg gain in 1-2 days signals fluid retention — alert cardiology), potassium coordination with diuretic regimen (loop = supplement, K-sparing = limit), thiamine if on loop diuretics, alcohol limit. This is NEVER a replacement for cardiology + GDMT (guideline-directed medical therapy). Get cardiac rehab supervision before independent training.
