Cat Heart Disease: Signs and Treatment
Understanding Feline Heart Disease
Heart disease affects approximately 15% of cats, with hypertrophic cardiomyopathy (HCM) being the most common form. Unlike dogs, cats rarely show obvious symptoms until the disease is advanced.
Early Warning Signs
- Decreased activity or reluctance to jump
- Rapid or labored breathing (especially while sleeping)
- Decreased appetite and weight loss
- Fainting episodes or sudden collapse
- Fluid buildup in abdomen or lungs
Hypertrophic Cardiomyopathy (HCM)
HCM causes thickening of the heart muscle, reducing the heart's ability to pump blood efficiently. It is most common in Maine Coons, Ragdolls, and British Shorthairs due to genetic mutations. However, any breed can develop HCM.
Diagnosis
Key diagnostic tools include echocardiogram (ultrasound of the heart), chest X-rays, blood tests (NT-proBNP for cardiac stress), and blood pressure measurement. Annual cardiac screening is recommended for at-risk breeds.
Treatment Options
- Beta-blockers (atenolol) to slow heart rate
- ACE inhibitors to reduce blood pressure
- Diuretics for fluid buildup
- Anticoagulants to prevent blood clots
Prognosis
Cats diagnosed early and managed with medication can live 2-5+ years with good quality of life. Regular monitoring and medication adjustments are essential.
