That is completely a false statement. Nitro relieves chest pain
but relaxing (vasodilation
) the vessel walls allowing more oxygen
to get to the heart muscle. As chest pain is caused by lack of oxygen to the heart muscle. One of the MOST common side effects of Nitro is a headache and hypotension
(low blood pressure). There is probably more of a chance that the pain is not cardiac related if the chest pain does not go away with nitro.
