Pharma 29: Heart Failure - Supporting the Failing Pump

This episode reframes heart failure as a syndrome of maladaptive compensation. What begins as the body’s attempt to preserve perfusion—fluid retention, vasoconstriction, neurohormonal activation—gradually accelerates damage and inefficiency. We explore heart failure therapy as a coordinated effort to unload the heart, interrupt harmful signals, and restore forward flow over time. When understood mechanistically, modern regimens feel coherent rather than crowded.Key takeaways you’ll build and reuse throughout the series:* Heart failure as a systems problem: preload, afterload, contractility, and neurohormonal drive interacting over time.* Compensatory pathways revisited: why the renin–angiotensin–aldosterone system and sympathetic activation worsen outcomes chronically.* Drug classes as roles, not lists: diuretics for congestion, vasodilators for load reduction, beta-blockers for remodelling, and mineralocorticoid antagonists for signal interruption.* Time as therapy: why some drugs feel worse before they work, and why patience improves survival.* Clinical priorities: relieving symptoms, preventing hospitalisation, and extending meaningful life.
