Name of the Condition

• Obstructive Hypertrophic Cardiomyopathy (HCM)

Summary

• Obstructive hypertrophic cardiomyopathy is a disorder where the heart muscle thickens abnormally, particularly affecting the septum between the ventricles. This can obstruct blood flow out of the heart, leading to various health issues.

Causes

• The primary cause of obstructive HCM is genetic mutations, which are often inherited. These mutations affect the proteins in heart muscle cells.

Risk Factors

• Family history of HCM.
• Genetic predisposition due to certain gene mutations.

Symptoms

• Symptoms may include shortness of breath, chest pain, palpitations, dizziness, and fainting, especially during or after physical activity.

Diagnosis

• Diagnosis typically involves a combination of physical examination, echocardiogram, electrocardiogram (ECG), and sometimes genetic testing.

Treatment Options

• Treatment may include medications such as beta-blockers or calcium channel blockers to reduce heart workload and control symptoms.
• Surgical procedures like septal myectomy or non-surgical options such as alcohol septal ablation may be employed to remove or reduce the thickened heart muscle.
• Implantable cardioverter-defibrillators (ICDs) may be recommended for those at risk of sudden cardiac death.

Prognosis and Follow-Up

• With appropriate management, many individuals lead a normal life, but regular follow-up is crucial to monitor heart function and adjust treatments as necessary.

Complications

• Possible complications include heart failure, atrial fibrillation, or sudden cardiac death if not properly managed.

Lifestyle & Prevention

• Lifestyle changes such as avoiding strenuous exercise and managing stress can help manage symptoms.
• While genetic nature makes prevention difficult, early detection in at-risk individuals can aid in managing the condition effectively.

When to Seek Professional Help

• Seek immediate medical attention if experiencing severe chest pain, rapid heart rate, or fainting episodes.

Tips for Medical Coders

• Ensure accurate coding by confirming the diagnosis of HCM involves an obstructive component.
• Be aware of closely related codes for non-obstructive hypertrophic cardiomyopathy to avoid confusion.
