Flashcards in Kidney and Heart Deck (4):

What are the 3 major ways that BP is regulated that involve the kidney?

Epinephrine & norepinephrine (from adrenal medulla)

Renin-angiotensin-aldosterone system (renin from kidney, aldosterone from adrenal cortex)

Vasopressin (ADH-- from posterior pituitary)


What is the effect of vasopressin?

Increased H2O retention, Increased vasoconstriction


How do you distinguish heart failure from kidney failure?

On a physical exam you can't distinguish! Salt/water retention, congestion, edema, neck vein distention

Kidney failure: you'll have uremic toxins, anemia

Heart failure: you'll have low cardiac output

BUT-- heart failure leads to kidney failure and vice versa = cardiorenal syndrome so you can think of them as the same thing


What is cardiorenal syndrome?

1. Decreased kidney function

2. Therapy-resistant heart failure with congestion -- diuretic resistance

3. Worsening kidney function during heart failure therapy
