Cardiology/Hypertension

Enalapril for Cardiomyopathy and CHF

 “Enalapril maleate is an angiotensin-converting enzyme (ACE) inhibitor labeled to treat mild to severe heart failure in dogs.” Research has shown that enalapril in combination with diuretics - with or without digitalis glycosides - “produces statistically significant clinical improvement in dogs with advanced heart failure due to mitral regurgitation or dilated cardiomyopathy” and has demonstrated “beneficial hemodynamic and clinical effects of adding enalapril to conventional therapy for dogs with CHF... Dogs treated with enalapril and conventional CHF therapy survived two times as long as did those receiving standard therapy alone.”
  Enalapril has also “been effective in treating cardiomyopathy and CHF in cats and ferrets, and its effects on blood pressure in horses and camels have been studied.” Because enalapril is a prodrug and can not be converted to its active form enalaprilat in patients with severe liver dysfunction, captopril or lisinopril might be a better choice in those patients. Renal function should be checked before starting enalapril therapy and at least every two months thereafter. The most common side effects are gastrointestinal, but there have been reports of enalapril-induced cough in dogs and a bird. Hypotension is a major concern if overdose occurs. NSAIDs, including aspirin, may reduce enalapril’s effect. The injectable form (enalaprilat) should not be given orally because it is very poorly absorbed.
   “The recommended dose for enalapril in dogs is 0.5 mg/kg orally every 12 to 24 hours. The dose for cats is 0.25 to 0.5 mg/kg orally every 12 to 24 hours.”

Amlodipine to Treat Feline Systemic Hypertension

  Amlodipine, a calcium channel blocker, has an antihypertensive effect in cats with coexistent systemic hypertension and renal insufficiency. Its use may improve the prognosis for cats with systemic hypertension by decreasing the risk of ocular injury or neurologic complications induced by high blood pressure (BP). In a retrospective study, medical records from 69 cats with systemic hypertension and hypertensive retinopathy were reviewed. 68.1% of the cats were referred because of vision loss; retinal detachment, hemorrhage, edema, and degeneration were common findings. Amlodipine decreased BP in 31 of 32 cats and improved ocular signs in 18 of 26 cats. Primary hypertension in cats may be more common than currently recognized.
    In a study at the Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Florida, amlodipine was shown to be a safe and effective once-daily antihypertensive agent when administered to cats at a dosage of 0.18 +/- 0.03 mg/kg daily as monotherapy. Researchers at the Department of Medical Sciences, University of Wisconsin-Madison, administered amlodipine at an oral daily dosage of 0.625 mg per cat (range = 0.08 to 0.23 mg/kg body weight). Average indirect systolic blood pressure measurements in those 12 cases decreased significantly from 198 to 155 mmHg during amlodipine treatment. Significant changes in body weight and serum creatinine and potassium concentrations were not detected.
 
Relationship between ocular lesions and hypertension
 Retinal lesions, caused predominantly by choroidal injury, are common in cats with hypertension. Hypertension should be considered in older cats with acute onset of blindness; retinal edema, hemorrhage, or detachment; cardiac disease; or neurologic abnormalities. Cats with hypertension-induced ocular disease should be evaluated for renal failure, hyperthyroidism, diabetes mellitus, and cardiac abnormalities. Blood pressure measurements and funduscopic evaluations should be performed routinely in cats at risk for hypertension (preexisting renal disease, hyperthyroidism, and age > 10 years).
