Q

What’s first line for angina relief

A

Short acting nitrates + B blockers or CCB to lower heart rate
- give CCB-DHP if heart rate is already low

Q

Organic nitrates mechanism of action

A

Relax vascular smooth muscles by intracellular conversion to nitrate ions then to NO -> increases CGMP -> relaxation
