All geriatric pets should also be routinely checked for hypertension.
Numerous studies in the veterinary literature show that a large percentage of cats more than 12 years of age have hypertension, either secondary to chronic renal disease or from underlying thyroid disease.
Diseases commonly associated with hypertension in both the dog and cat, include:
- Renal disease
- Hyperadrenocorticism (Cushings disease) (dogs)
- Hyperthyroidism (cats)
- Systemic hypertension
A systolic blood pressure is elevated in an unstressed, awake, dog or cat if it is consistently greater than 170-180 mmHg in the cat, or greater than 180 mmHg in the dog”.
In a recent study, 61% of cats and 93% of dogs with chronic renal failure also had systemic hypertension.
87% of cats with untreated hyperthyroidism had systemic hypertension.
