Types of Hypertension
|
Two types:
-Essential (primary or idiopathic) -Secondary |
|
|
Essential Hypertension
|
Essential is the most common type which involves several interacting homeostatic mechanisms.
|
|
|
Secondary Hypertension
|
Secondary would be related to a systemic disease that raises perhiperal vascular resistance or cardiac output.
|
|
|
Diseases that cause Hypertension
|
Diseases include: Renovascular disease, renal parenchymal disease, pheochromocytoma, primary hyperaldosteroniam, cushing’s disease, and diabetes mellitus.

Understanding Hypertension
|
The Kidney releases renin into the blood stream>> Renin helps convert angiotensin to angiotensin 1 in the liver>> angiotensin 1 is converted to angiotensin 2 (a potent vasoconstrictor) IN THE LUNGS>> A2 causes arteriolar constriction and ALDOSTERONE SECRETION>>Aldosterone causes Na & H20 retention>> retained Na & H20 increase BLOOD VOLUME>> Arteriolar constriction increases peripheral vascular resistance>> Increased blood volume and vascular resistance cause Hypertension
