Pet Insurance for Heart Disease (Cardiac Disease)

What is Heart Disease (Cardiac Disease)?

Heart disease encompasses a range of conditions affecting the heart's structure and function. In dogs, the most common forms are mitral valve disease (MVD) in small breeds and dilated cardiomyopathy (DCM) in large breeds. In cats, hypertrophic cardiomyopathy (HCM) is the most prevalent. Heart disease is often progressive, and while it cannot be cured, early detection and treatment can significantly extend life and maintain quality of life.

Symptoms

Diagnosis & Treatment

Diagnosis involves cardiac auscultation (listening for murmurs and arrhythmias), chest X-rays, echocardiography (ultrasound of the heart — the gold standard), electrocardiogram (ECG), and blood tests (proBNP, cardiac troponin). Echocardiography provides detailed assessment of chamber sizes, wall thickness, valve function, and blood flow patterns.

Treatment depends on the type and stage of heart disease. Common medications include ACE inhibitors (enalapril, benazepril), diuretics (furosemide) for fluid management, pimobendan for improved heart function, anti-arrhythmic drugs, and blood pressure medications. Dietary sodium restriction and moderate exercise are recommended. Advanced cases may require oxygen therapy, thoracocentesis (fluid drainage), or referral to a veterinary cardiologist.

Insurance Coverage for Heart Disease (Cardiac Disease)

Heart disease is covered by all major pet insurance carriers as a chronic illness. Given the high ongoing costs for medications, diagnostics, and specialist visits, insurance is essential. Healthy Paws covers all aspects of cardiac care — echocardiograms, medications, specialist consultations, and emergency treatment — with unlimited payouts.

Prevention Tips

While most heart disease is genetic and cannot be prevented, early detection dramatically improves outcomes. Annual cardiac screening (auscultation) for all pets, with echocardiography for at-risk breeds starting at age 2–3. Feed a balanced diet with adequate taurine (especially for cats and breeds prone to DCM). Maintain a healthy weight and provide regular, moderate exercise.
