🫀 Restrictive Cardiomyopathy vs Constrictive Pericarditis
Two important causes of diastolic heart failure with preserved EF—but with different underlying mechanisms.
🔹 Restrictive Cardiomyopathy → Stiff myocardium + reduced e′ + minimal respiratory variation.
🔹 Constrictive Pericarditis → Rigid pericardium + preserved/normal e′ + marked respiratory variation.
💡 Clinical Pearl:
The key is to assess the pericardium, tissue Doppler, and respiratory variation together.
