Cardiomyopathy

Conditions

Cardiomyopathy is disease of the heart muscle itself, distinct from problems in the coronary arteries or valves. The major forms include dilated cardiomyopathy (an enlarged, weakened heart), hypertrophic cardiomyopathy (an abnormally thickened muscle), restrictive cardiomyopathy (a stiff heart that cannot relax properly), and infiltrative cardiomyopathies such as cardiac amyloidosis. Each behaves differently, but all require specialized expertise to diagnose accurately, identify reversible causes, optimize medical therapy, and decide when device therapy, transplantation, or referral to a heart-failure program is appropriate. The therapeutic landscape has shifted dramatically in the last decade, particularly for amyloid heart disease, hypertrophic cardiomyopathy, and certain genetic dilated forms. Dr. Kedan combines advanced echocardiographic assessment with thoughtful workup for reversible drivers and close coordination with Cedars-Sinai when more specialized care is needed.

What Cardiolucent Evaluates

  • Advanced echocardiography with strain imaging to detect subtle dysfunction and characterize subtype
  • POCUS at every visit for interval reassessment of function and chamber sizes
  • Workup for reversible causes: alcohol, tachycardia, chemotherapy, hypothyroidism, iron overload
  • Cardiac MRI coordination at Cedars-Sinai for tissue characterization when indicated
  • Screening for cardiac amyloidosis when imaging or clinical clues suggest it
  • Genetic testing and family screening for inherited cardiomyopathies
  • BNP/NT-proBNP, troponin, and comprehensive metabolic monitoring
  • Device-therapy evaluation (ICD, CRT) coordinated with electrophysiology

Common Symptoms

  • Shortness of breath with exertion or when lying flat
  • Reduced exercise capacity and persistent fatigue
  • Leg swelling and weight gain from fluid retention
  • Palpitations or new atrial fibrillation
  • Chest discomfort, particularly with exertion in hypertrophic cardiomyopathy
  • Lightheadedness or syncope, occasionally with exertion
  • Family history of sudden cardiac death — a critical warning sign in genetic forms
  • Some patients are minimally symptomatic despite significant disease, especially early in the course

Risk Factors

  • Family history of cardiomyopathy, heart failure, or sudden cardiac death
  • Genetic mutations (sarcomeric, lamin, transthyretin, and others)
  • Prior viral myocarditis
  • Long-standing uncontrolled hypertension
  • Excess alcohol intake
  • Chemotherapy or chest radiation exposure
  • Iron overload (hemochromatosis) and other infiltrative diseases
  • Untreated thyroid disease
  • Peripartum period in women
  • Chronic uncontrolled tachyarrhythmias

How Cardiolucent Approaches Treatment

Treatment is subtype-specific and built on a careful diagnostic foundation. Dilated cardiomyopathy generally responds well to guideline-directed medical therapy with beta-blockers, ACE/ARB/ARNI, mineralocorticoid receptor antagonists, and SGLT2 inhibitors, with device therapy reserved for those who qualify. Hypertrophic cardiomyopathy has newer targeted options such as mavacamten. Cardiac amyloidosis is increasingly treatable with disease-modifying therapy. Reversible causes — alcohol, tachycardia, hypothyroidism, iron overload — are addressed at their source whenever possible. Dr. Kedan personally manages medication titration, surveillance, and timing of advanced therapies, coordinating with electrophysiology, heart-failure specialists, and the genetics program at Cedars-Sinai as needed.

Common Questions

Frequently Asked Questions

What is cardiomyopathy?
Cardiomyopathy is a disease of the heart muscle itself, distinct from problems in the coronary arteries or valves. The major forms include dilated cardiomyopathy (an enlarged, weakened heart), hypertrophic cardiomyopathy (an abnormally thickened muscle), and restrictive cardiomyopathy (a stiff heart that cannot relax properly). Each behaves differently, but all require careful diagnosis and specialized management.
What are the symptoms?
Common symptoms include shortness of breath, reduced exercise capacity, fatigue, palpitations, swelling in the legs, chest discomfort, and occasionally fainting. Some patients have minimal symptoms despite significant disease, which is one reason cardiomyopathy is often underdiagnosed. New or worsening shortness of breath, syncope, or fainting deserves prompt evaluation.
What causes cardiomyopathy?
Causes are diverse and include genetic mutations, prior viral infection, long-standing hypertension, valve disease, alcohol or chemotherapy exposure, infiltrative diseases such as amyloidosis, and metabolic conditions. Some cases are idiopathic, meaning no specific cause is identified. Dr. Kedan looks systematically for reversible causes because identifying one can change the entire treatment plan.
How is cardiomyopathy diagnosed?
Diagnosis typically combines echocardiography — including advanced strain imaging that can detect subtle dysfunction — with EKG, cardiac biomarkers, and often cardiac MRI for tissue characterization. POCUS at the office allows Dr. Kedan to track changes over time without delay. Genetic testing is added when family history or imaging suggests an inherited form.
Is cardiomyopathy hereditary?
Many forms of cardiomyopathy — particularly hypertrophic and certain dilated variants — have a strong genetic component, and first-degree relatives may benefit from screening. Identifying a genetic cause also informs prognosis and treatment selection. Schedule a consultation with Dr. Kedan to discuss whether genetic testing and family screening make sense for your situation.
How is cardiomyopathy treated?
Treatment depends on the type but typically includes guideline-directed medical therapy (GDMT) for heart failure, rhythm management, and treatment of any reversible underlying cause. For specific forms — such as cardiac amyloidosis, hypertrophic cardiomyopathy, or genetic dilated cardiomyopathy — newer targeted therapies have transformed outcomes. Dr. Kedan tailors the regimen to your specific subtype and adjusts as your heart responds.
Will I need a defibrillator?
Some patients with cardiomyopathy are at elevated risk for life-threatening rhythms and benefit from an implantable cardioverter-defibrillator (ICD). The decision depends on your ejection fraction, symptoms, genetic findings, family history of sudden death, and other factors. Dr. Kedan coordinates with electrophysiology when device therapy is being considered so the recommendation reflects a complete picture.
Can cardiomyopathy be reversed?
Reversible causes — such as alcohol-induced or tachycardia-induced cardiomyopathy — can often improve substantially when the underlying trigger is addressed. Genetic and idiopathic forms cannot be cured, but modern medical therapy frequently improves heart function and symptoms significantly, and many patients live full, active lives. Early diagnosis is the single biggest factor in long-term outcome.
How closely will I be followed?
Most patients are seen every 3–6 months for symptom assessment, medication optimization, and POCUS reassessment, with repeat formal echocardiography on a schedule tailored to your subtype. Visits are more frequent during medication initiation or when symptoms shift. The concierge model means you can reach Dr. Kedan directly between visits when something changes.
