Heart attacks can come in several forms, including an ST segment elevation myocardial infarction (STEMI). This form of heart attack occurs when the blood supply to the heart is cut off for prolonged periods of time. When one of these attacks occurs, there are several symptoms that can signal that the STEMI is happening so you can get call an ambulance and get to the hospital before it's too late.

Pain and Pressure

Pain and pressure are two of the main symptoms of a STEMI that are most recognisable. A STEMI may first manifest as a squeezing pressure at the centre of your chest, which may transition into serious atypical chest pain that radiates from the chest to the shoulders and upper arm, and may even be felt into the back, neck and jaw, suggests


A STEMI can be seen externally through the way your skin reacts. For example, with the blood supply being affected, your skin may take on a pale colour. Your body may also become diaphoretic and start pouring sweat from your pores, even if you are in a cold room or not currently performing any physical activity. The skin may also be cool to the touch, even though it looks like you're overheating.


One common symptom of a STEMI is dyspnea, or difficulty breathing, which can vary in severity. This symptom is often one of the first signs of the heart attack and can start even days or weeks before the actual event occurs, according to the Merck Medical Library.

Other Possible Symptoms

Several other symptoms may accompany a STEMI heart attack and may vary on presence and severity depending on your unique situation. These symptoms may include, vomiting, nausea, dizziness, fainting, jugular vein distension, weakness, or a feeling of impending doom.
