Hypertension - Coggle Diagram

- - - - if this does not work, combine with CCB or thiazide like diuretic
- - - - decreased glom filtration rate leads to more renin and higher bp
    - - salt and water retention and fluid overload
    - - hydronephrosis, and the back-pressure on the kidneys can result in renal failure and elevated blood pressure
    - - excessive secretion of epinephrine (adrenaline) and norepinephrine (noradrenaline)
    - - cortisol enhances the vasoconstrictor effect of catecholamines
    - - Excess thyroxine -> increased SNS effect -> increase vascular resistance + cardiac output
    - - heart rate is slowed and there is an increase in peripheral vascular resistance to compensate
    - - mechanism is unclear but may involve oxidative stress secondary to hypoxia and sympathetic autonomic activation.
    - - SNS activation
    - - progesterone effect on small blood vessels
