What is Angina ?
What does angina mean?1
Angina, also called angina pectoris, is a type of chest pain or discomfort caused by an imbalance between what your heart needs in oxygen (oxygen demand) and what your heart receives in oxygen (oxygen supply). In other words, it’s when your heart isn’t receiving enough oxygen-rich blood.
It feels like pain, pressure, tightness, or discomfort in your chest but can also express itself in your arms, back, shoulders, neck, jaw, or tummy.
