• Diuretics: These are used to manage fluid retention, a common symptom in patients with DCM. Furosemide is a typical diuretic that helps reduce swelling and improve breathing[3].

2. Advanced Heart Failure Therapies

• Aldosterone Antagonists: Medications such as spironolactone can help prevent the progression of heart failure by blocking the effects of aldosterone, a hormone that can contribute to fluid retention and heart remodeling[4].
• SGLT2 Inhibitors: Recently, sodium-glucose cotransporter-2 (SGLT2) inhibitors have shown promise in heart failure management, providing benefits in reducing hospitalization rates and improving outcomes[4].

3. Anticoagulation Therapy

• Patients with DCM may be at increased risk for thromboembolic events due to reduced cardiac output. Anticoagulants may be prescribed to prevent blood clots, especially in patients with atrial fibrillation[4].

Lifestyle Modifications

1. Dietary Changes

• A heart-healthy diet low in sodium and saturated fats is recommended. Patients are often advised to follow the DASH (Dietary Approaches to Stop Hypertension) diet, which emphasizes fruits, vegetables, whole grains, and lean proteins[3].

2. Physical Activity

• Regular, moderate exercise can improve cardiovascular health and overall well-being. However, exercise regimens should be tailored to the individual's capacity and should be discussed with a healthcare provider[3].

3. Weight Management

• Maintaining a healthy weight is crucial for managing symptoms and reducing the strain on the heart. Weight loss may be recommended for overweight patients[3].

Surgical Interventions

1. Implantable Cardioverter-Defibrillator (ICD)

• For patients at risk of life-threatening arrhythmias, an ICD may be implanted to monitor heart rhythms and deliver shocks if dangerous arrhythmias occur[4].

2. Cardiac Resynchronization Therapy (CRT)

• CRT is a specialized form of therapy for patients with heart failure and electrical conduction issues. It involves the implantation of a device that coordinates the contractions of the heart's chambers, improving efficiency and symptoms[4].

3. Heart Transplantation

• In severe cases where other treatments are ineffective, heart transplantation may be considered. This is typically reserved for patients with end-stage heart failure who meet specific criteria[4].
