Endocrine hypertension in cats is more prevalent than previously thought. Predominant causes are primary hyperaldosteronism (Conn’s disease), hyperthyroidism and diabetes mellitus. Other endocrine disorders with an impact on blood pressure rarely occur in the cat. Reliable measurement of both systolic and diastolic blood pressure is vital in identifying hypertension associated with these disorders. An understanding of blood pressure regulation and of the pathophysiology of hypertension development facilitates appropriate diagnostic and therapeutic efforts. Even if other causes of hypertension in a patient are found such as chronic kidney disease, it is important to realize that an underlying endocrine disorder may have been precipitating the renal damage.

Pulse wave analysis

 

High definition oscillometry (HDO) is a patented new technology, allowing very sensitive and fast analysis of incoming signals and even real-time assessment of the pulse wave. Due to its speed, it scans incoming signals and actually measures all 3 pressures: systolic, diastolic and ...
