Wrong statement about nitrates:
a) Predominantly venodilators
b) Have coronary vasodilator effects
c) Contraindicated in vasospastic angina
d) Should be avoided in hypotensive patients
Correct answer: c) Contraindicated in vasospastic angina
Nitrates are useful in vasospastic angina. Non selective betablockers like propranolol are avoided in vasospastic angina as they can cause alpha overactivity. Nitrates are contraindicated in those on phosphodiesterase-5 inhibitor sildenafil.
