Does unstable angina have ST depression?

The diagnosis of unstable angina and non-STEMI is predominantly based on the ECG and cardiac enzymes. Physical examination, as previously described, is non-specific. The ECG tracing can have multiple abnormalities, but, by definition, there is no ST segment elevation. The most common finding is ST segment depression.

People also ask, is unstable angina relieved by nitroglycerin?

Nitroglycerin, also referred to as “nitro,” has been used with success for more than a century to treat angina. Nitroglycerin is a useful medication to help patients with CAD “reintroduce” physical activity into their lives. Nitroglycerin may alleviate the discomfort of both stable and unstable angina.
