Heart attack. A heart attack occurs when an artery supplying your heart with blood and oxygen becomes blocked. Fatty deposits build up over time, forming plaques in your heart's arteries. If a plaque ruptures, a blood clot can form and block your arteries, causing a heart attack.

A myocardial infarction (MI), also known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw.

Heart attacks can strike at any age—and they're twice as likely to be fatal for young women than men. When you picture the typical heart attack patient, it's probably an older man clutching his arm and grimacing in pain.

A heart attack is common terminology for myocardial infarction (MI). An MI occurs when a coronary artery, one of the arteries that supplies blood to the heart muscle, becomes suddenly blocked. The sudden blockage robs a portion of the heart muscle of its vital blood supply, and the muscle dies.

Heart Attack and Sudden Cardiac Arrest Differences. People often use these terms interchangeably, but they are not synonyms. A heart attack is when blood flow to the heart is blocked, and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly.

Does blood pressure change during a heart attack? During a heart attack, blood pressure can rise, fall, or stay the same. As a result, blood pressure change without other symptoms is not a reliable sign of a heart attack.

Abnormal heart rhythms (arrhythmias), which occur in more than 90% of the people who have had a heart attack. Loss of consciousness, which sometimes is the first symptom of a heart attack. Feelings of restlessness, sweatiness, anxiety and a sense of impending doom. Bluishness of the lips, hands or feet.

A heart attack happens when a blood vessel that supplies the heart is blocked. The lack of oxygen-rich blood causes the affected parts of the heart muscle to die. Chest pain from a heart attack feels like a pressure, squeezing, burning, or pain in the middle or left side of your chest.

Every 20 seconds a heart attack occurs and a heart attack fatality occurs about every minute. 2. Almost 14 million Americans have a history of heart attack or angina. Like a heart attack, angina occurs when the vessels that supply blood to the heart narrow and prevent oxygen-rich blood from reaching the heart.

A silent heart attack is a heart attack that occurs without clear symptoms, or sometimes without any symptoms at all. This causes the heart attack to go unnoticed, often being recognized only days, months or even years following its presentation. As circulation is affected, part of the heart muscle dies.

Someone having a heart attack may experience any or all of the following: Uncomfortable pressure, fullness or squeezing pain in the center of the chest. Discomfort or pain spreading beyond the chest to the shoulders, back, neck, jaw, teeth, or one or both arms, or occasionally upper abdomen. Shortness of breath.

Most heart attacks occur as the result of an immediate and sudden blockage of the arteries, Dr. Asfour says. As a result, the heart muscle loses nutrients and blood supply. “That could lead to arrhythmia, or irregular heartbeats, a weakening of the heart muscle and ultimately, congestive heart failure.”

In summary, there is a difference between a heart attack and a cardiac arrest. A heart attack occurs when the blood supply to part of the heart stops and thus causes a section of the heart muscle to begin to die; whereas a cardiac arrest occurs when the heart stops beating as a whole.

People often use these terms interchangeably, but they are not synonyms. A heart attack is when blood flow to the heart is blocked, and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly.

If the beat gets out of rhythm, this could be a sign you're having a heart attack. Heart palpitations due to heart attack can create a sense of unease or anxiety, especially in women. Some people may describe heart palpitations as a sensation their heart is pounding in their neck, not just their chest.
