Heart Attack Symptoms and Early Warning Signs

Chest pain or pressure is the most common symptom of a heart attack; however people who are having a heart attack may experience a variety of conditions that include jaw pain, sweating, heartburn, shortness of breath, jaw pain, toothache, headache, and nausea and vomiting.

What causes heart attacks?
Most of the deaths from heart attacks are caused by ventricular fibrillation of the heart that occurs before the victim of the heart attack can reach an emergency room. Those who reach the emergency room have an excellent prognosis; survival from a heart attack with modern treatment should exceed 90%. The 1% to 10% of heart attack victims who die later include those victims who suffer major damage to the heart muscle initially or who suffer additional damage at later.

A heart attack (also known as a myocardial infarction or MI) is caused by blocked blood flow to part of the heart, resulting in damage to heart muscle. Heart attack signs and symptoms can vary greatly, sometimes with immediate and intense chest pain but more often starting slowly with chest tightness and pain that may persist for hours or days.

A heart attack is a serious medical condition that requires emergency treatment to minimise damage to the heart and reduce risk of sudden cardiac arrest. It is crucial to recognise the symptoms of heart attack and call 111 immediately if you think that you or someone you’re with might be having a heart attack.

A heart attack is often confused with sudden cardiac arrest. A heart attack is the disruption of blood flow to part of the heart and is not normally fatal. A heart attack does, however, increase the risk of sudden cardiac arrest ie: the disruption of the heart’s pumping action that stops blood flow to the rest of the body and causes loss of consciousness, absence of pulse, and (if the heart cannot be re-started) death.

How many people have heart attacks each year?
Heart attack, or myocardial infarction, is the number one killer of both men and women in the U.S. Each year, about 735,000 Americans suffer a heart attack, and heart disease is the leading cause of death for both men and women in the US.
