Feline cardiomyopathy causes heart walls to thin and pump ineffectively. Blood then backs up and fluid can fill lungs causing congestion, coughing and shortness of breath.
Heart
High blood pressure, thyroid disorders, genetics and diet contribute to complex cat cardiovascular disease onset and progression.
Underlying Causes Vary
Congestive heart failure may develop slowly over months or years or can manifest unexpectedly in cats with an arrhythmic crisis event.
Sudden Onset
Labored breathing, diminished activity tolerance, weight loss and fainting suggest compromised heart function requiring prompt veterinary diagnosis.
Warning Signs
Depending on severity, long term medications help strengthen contraction, lower blood pressure, reduce fluid and help oxygenate to reduce demands on the compromised feline heart.
Ongoing Medications
Salt/sodium promotes fluid retention worsening lung congestion. Prescribing reduced sodium therapeutic diets helps cats excrete excess.
Modifications Aid
Encourage relaxed activities cats can enjoy in short intervals without overexertion and arrange soft indoor areas to comfortably rest when fatigued.
