1) Angina (discomfort or pain within the center of the chest);
2) Difficulty breathing (if your heart is not receiving an adequate supply of blood, fluid can begin to build up within your lungs and cause significant breathing problems);
3) Nausea (additional gastrointestinal symptoms such as abdominal pain or vomiting can also occur);
4) Dizziness (a blocked artery within the heart prevents oxygenated blood from reaching the brain);
5) Irregular heartbeat (if your heart is not receiving enough blood due to the blockage, it will start pumping faster to try to bring more blood into the heart).
