What is the pathophysiology of hypertension answer shoud be in flow chart form?
Hypertension Pathophysiology
Primary (Essential) Hypertension
- Exact cause is unknown
- Multiple factors contribute, including:
- Genetic predisposition
- Environmental factors, such as:
- Obesity
- Physical inactivity
- Excessive sodium intake
- Alcohol consumption
- Smoking
- Increased sympathetic activity
-Activation of Renin Angiotensin Aldosterone system resulting in Vasocostriction and fluid retention
Increased peripheral vascular resistance
Structural changes in the arterioles
- Thickening of the arterial wall
- Decreased elasticity of the arterial wall
Increased cardiac output
- Increased heart rate
- Increased stroke volume
Secondary Hypertension
- Caused by an underlying medical condition, such as:
- Kidney disease
- Endocrine disorders, such as Cushing's syndrome
- Thyroid disease
- Diabetes
- Impaired kidney function
- Decreased ability of the kidneys to excrete sodium
- Fluid retention
- Increased vascular resistance
Increased secretion of adrenal hormones
- Aldosterone
- Cortisol
Increased cardiac output
- Increased heart rate
- Increased stroke volume
Consequences of Hypertension
- Increased risk of:
- Stroke
- Heart failure
- Myocardial infarction
- Kidney failure
- Retinal detachment
- Cognitive impairment
- Dementia
