'''Description:'''

*Hypertension is defined as the pathological elevation of arterial blood pressure.

*There are two main types of hypertension, systemic hypertension (affects the systemic circulation) and pulmonary hypertension (affects the pulmonary circulation).

*Blood pressure in veterinary patients is not measured routinely; therefore hypertension is usually only diagnosed after clinical signs become apparent.

===Systemic Hypertension===

*Primary systemic hypertension= idiopathic increase in arterial blood pressure

*Secondary systemic hypertension=increase in arterial blood pressure secondary to a pathological process

*The ocular system, cardiovascular system, and nervous system are the most vulnerable to elevated arterial blood pressures. However, some endocrine disturbances have also been found to predispose animals to hypertension.

====Signalment====

'''Dogs''': male>female; obese animals; middle to old age

'''Cats''': middle to old age

====Diagnosis====

=====History & Clinical Signs=====

*Signs are the result of ischemia, edema, and/or haemorrhage of the affected areas

=====Neurological Signs=====

-Depression

-Seizures

-Syncope

-Paresis

-Vestibular Signs

-Ataxia

=====Cardiac Signs=====

-Left Ventricular Hypertrophy

-Heart Failure

-Systolic Murmur

-Gallop rhythm

=====Ocular Signs=====

*In cats, ocular abnormalities from hypertension are usually the first thing detected.

-Blindness

=====Fundic Examination=====

-Hyphemia (Blood in the anterior chamber)

-Retinal Haemorrhage

-Retinal Detachment

-Retinal Degeneration

=====Renal Signs=====

*Renal disease can both be caused by hypertension and cause hypertension.

*Chronic renal failure is the most common cause of hypertension showing clinical signs in dogs and cats.

-Renal Disease (especially glomerular damage)

*Glomerular damage allows protein leakage, therefore animals with hypertension are more proteinuric than unaffected animals

=====Endocrine Signs=====

-Hyperthyroidism (cats)

-Hyperadrenocorticism, Diabetes Mellitus (dogs)

=====Physical Exam=====

'''Blood Pressure Measurement'''

*Systolic Pressure> 175 indicates hypertension in a relaxed dog or cat

*Diastolic Pressure> 100 indicates hypertension in a relaxed dog or cat

'''1. Direct Blood Pressure Measurement (Invasive)
'''

*Uses an indwelling arterial catheter

-Measures systolic, diastolic, and mean arterial pressures

-Used on very ill patients or those undergoing anaesthesia

'''2. Indirect Blood Pressure Measurement (Non-invasive)
'''

*Two types that measure systolic arterial pressure

-Doppler Flow Technique: good for large dogs, poor for cats

-Oscillometric Technique: good for small dogs, good for cats

=====Treatment=====

'''Cats'''

*Treat the underlying problems

*Calcium Channel Blocker (e.g. amlodipine)

*Monitor Blood Pressure

'''Dogs'''

*Treat the underlying problems

*Monitor Blood Pressure

'''Dogs with Renal Disease:'''

*ACE-inhibitor (e.g. enalopril): Given alone or in combination with some of the other treatments listed below.

*Calcium Channel Blocker (e.g. amlodipine)

*Sodium Restricted Diet

*Beta Blockers (e.g. atenolol)

*Diuretics (e.g furosemide)

*Vasodilators (e.g. enalopril)

=====Prognosis=====

-Cats with hypertension are more successfully treated than dogs.

-History and clinical signs may be suggestive of the disease, so upon physical examination a blood pressure measurement should be taken.&nbsp;Systolic Pressure&gt; 175 indicates hypertension in a relaxed dog or cat and diastolic Pressure&gt; 100 indicates hypertension in a relaxed dog or cat. However, most cats and many dogs are not relaxed when in the veterinary clinic environment so accurate readings can be difficult.

However, most cats and many dogs are not relaxed when in the veterinary clinic environment so accurate readings can be difficult.
-Methods of measuring blood pressure are the direct method, which is invasive. This uses an indwelling catheter to measure systolic, diastolic, and mean arterial pressures. This is usually saved for very ill patients or those undergoing anaesthesia. The indirect and non- invasive methods are Doppler Flow Technique which is good for large dogs, but very inaccurate for cats. Also the Oscillometric Technique which is best for small dogs and is good for cats too.
