Other restrictive cardiomyopathy
Clinical Classification Guidelines
Inclusion Terms
- Constrictive cardiomyopathy NOS
Medical Intelligence & Overview
Other restrictive cardiomyopathy, classified under ICD-10 code I42.5, is a condition where the heart's walls become stiff, limiting the heart's ability to fill properly during the relaxation phase. This form of cardiomyopathy is characterized by restricted movement of the heart muscle, which impairs normal blood flow and can lead to heart failure if untreated. Often referred to as constrictive cardiomyopathy, this condition differs from other types of cardiomyopathies because of its unique impact on the heart's shape and function.
Causes & Symptoms
Clinical Causes: Idiopathic (unknown origins) Scarring due to previous infections or inflammations such as myocarditis Systemic diseases like amyloidosis or sarcoidosis that deposit abnormal proteins in the heart tissue Radiation therapy involving the chest area Previous heart surgeries or radiation exposure Genetic factors that lead to abnormal tissue development in the heart Other secondary causes related to underlying health conditions
Key Symptoms: Shortness of breath, especially during exertion or when lying down Swelling in the legs, ankles, or abdomen Fatigue and weakness Palpitations or irregular heartbeat Persistent cough or wheezing Elevated jugular venous pressure Ascites (fluid accumulation in the abdominal cavity)
Diagnostic & Treatment
Diagnosis Path: Echocardiogram (ultrasound to observe heart structure and function) Cardiac MRI (detailed imaging of the heart tissue) Electrocardiogram (ECG or EKG to detect abnormal heart rhythms) Chest X-ray (to assess heart size and pulmonary congestion) Hemodynamic studies (cardiac catheterization to measure pressures within the heart) Biopsy (to examine tissue for underlying causes like amyloidosis)
Treatment Protocols: Medications such as diuretics to reduce fluid build-up ACE inhibitors or beta-blockers to manage symptoms and improve heart function Anticoagulants to prevent blood clots Treatment of underlying conditions (e.g., managing amyloidosis) Surgical interventions, including pericardiectomy (removal of constrictive pericardium) in certain cases Heart transplantation as a last resort for severe cases
