Define heart attack
A heart attack, also known as a myocardial infarction, is a serious and potentially life-threatening medical condition that occurs when the blood flow to the heart muscle is blocked or restricted. This typically happens due to the narrowing or blockage of the coronary arteries, which supply oxygen and nutrients to the heart. When the blood flow is interrupted, the heart muscle can become damaged or die if the blood flow is not restored quickly. Symptoms of a heart attack can include chest pain or discomfort, shortness of breath, fatigue, lightheadedness, nausea, or pain in the arms, back, jaw, or stomach. Prompt medical attention is crucial to minimize the damage to the heart and improve the chances of survival.
A heart attack, also known as myocardial infarction, refers to the damage or death of a part of the heart muscle due to a lack of oxygen-rich blood flow. It occurs when one or more of the coronary arteries that supply blood to the heart become blocked, usually as a result of a blood clot. This blockage prevents sufficient oxygen and nutrients from reaching the heart muscle, leading to its injury or death.
Common symptoms of a heart attack include chest pain or discomfort that may radiate to the arms, neck, jaw, or back. Other signs may include shortness of breath, sweating, nausea, light-headedness, and a feeling of impending doom.

To diagnose a heart attack, healthcare providers typically use various tests, including electrocardiogram (ECG/EKG), blood tests that measure cardiac enzymes, and imaging tests such as a coronary angiography, echocardiogram, or cardiac CT scan.
Preventive measures for heart attacks generally involve maintaining a healthy lifestyle. This includes regular physical exercise, a balanced diet, managing and controlling risk factors such as high blood pressure, high cholesterol levels, diabetes, obesity, and avoiding smoking or excessive alcohol consumption. Regular check-ups and consultations with a healthcare professional are also recommended to monitor and manage any potential risk factors.
A heart attack, also known as a myocardial infarction, occurs when there is a blockage or narrowing of the blood vessels that supply oxygen and nutrients to the heart muscle. This blockage is typically caused by a blood clot or the buildup of fatty deposits called plaque in the coronary arteries. Without adequate blood flow, the heart muscle becomes starved of oxygen and begins to die.
The symptoms of a heart attack can vary but commonly include:
1. Chest pain or discomfort: This often feels like pressure, tightness, or a squeezing sensation in the chest. The pain may radiate to the arms, back, neck, jaw, or stomach.
2. Shortness of breath: Difficulty breathing or feeling breathless, particularly during physical activity or while at rest.
3. Fatigue: Unusual tiredness or a feeling of weakness, especially in combination with other symptoms.
4. Sweating: Profuse sweating unrelated to exertion or hot weather.
5. Nausea or vomiting: Some people may experience these symptoms, often accompanied by abdominal discomfort.
Other signs can include lightheadedness or dizziness, a rapid or irregular heartbeat, or anxiety. It is important to note that symptoms can vary between men and women, and some individuals may even have a "silent" heart attack without any noticeable symptoms.
If someone is experiencing symptoms of a heart attack, it is critical to seek immediate medical attention. Emergency medical services should be called for prompt evaluation and treatment. Early intervention can help minimize the damage to the heart muscle and increase the chances of survival.
