Cardiac Pharmacology Flashcards
What is the equation for Cardiac output and systemic vascular resistance
What are the ABC’s for cardiac Anti hypertensives
What is the difference between ACE and ARB inhibitors
Ace inhibitors work to reduce or prevent the conversion of angiotensin 1 to angiotensin 2 (They prevent the formation of Angiotensin converting enzyme) This also prevents the formation of aldosterone.
ARD inhibitors antagonize or block the angiotensin II receptors, therefore prevent them from working. (Aldosterone is still made)
What are some common ACE & ARD inhibitors
What does a Beta blocker do
There are selective and non selective beta blockers
SELECTIVE beta blockers reduce chronotropic and inotropic effects to reduce HR
This decreases CO, which in turn reduces the pressure on the kidneys, ultimately reducing the release of renin
What are some common beta blockers
What do calcium channel antagonists do?
These block calcium channels, which help reduce the contractility of the heart and smooth muscle
What do Diuretics do?
These can come in many forms and work on different areas of the Kidneys. Essentially they promote more frequent urination
What are the ‘First line of defence in dyslipidaemia?
These are medicines that end in STATIN
Other meds can be used but not usually seen in practice as commonly
What is the difference between HDL & LDL
HDL (Hight Density Lipoprotein) is the Bad cholesterol that is associated with atherosclerosis
LDL (Low density Lipoprotien) are the ‘good’ cholesterol which transport cholesterol to the liver to be removed from the body
It is important to relise both of these types in higher concentration are BAD
What are some anti anginal medicines
Organic Nitrates are vasodilators. Which vasodilates the vessels resulting in more oxygen supply, reducing the signs of ischemia.
Selective beta blockers
And non selective beta blockers
Calcium channel blockers can also be a first-line defense
What is the Vaughan Williams Classification for anti arrhythmic/dysthymic
This is to group all the difference medicines into one claffication scale
How do we relate this classification to out cardiac action potential
