A

ischema of the heart muscle

19
Q

Myocardial infarction (MI)

A

heart attack

20
Q

Coronary artery disease (CAD)

A

plaque build up in the arteries cause them to narrow

21
Q

Hypertension

A

high blood pressure

22
Q

ACE inhibitors

A

relax blood vessels and reduce pressure

25
Q

Digitalis glycosides (from foxglove plant)

A

helps correct abnormal cardiac rhythm

26
Q

Diurectics

A

remove excess fluid and sodium from the body through increased urination

27
Q
