|
Heparin
|
|
|
What do nitrates do?
|
relax vascular smooth muscle promoting vasodilation,improve myocardial perfusion by dilating coronary arteries,decrease venous return by venous dilation and pooling,reduce LVEDV and pressure,decreases myocardial O2 demand and relieve chest discomfort due to ischemia
|
|
|
Nitrates are known as what type of drug?
|
antianginal
|
|
