Infarction refers to the death of tissue caused by the lack of blood supply, usually due to a blockage or interruption in the flow of blood to a particular area of the body.

Commonly known as a heart attack, myocardial infarction occurs when the blood supply to the heart muscle is obstructed, while cerebral infarction, commonly known as a stroke, occurs when the blood supply to the brain is interrupted. In both cases, recognizing the early signs and seeking immediate medical attention is crucial to prevent further damage and potentially save lives. In this article, we will discuss the signs of infarction that you should never ignore.

1. Chest Pain and Discomfort

One of the most common symptoms of a heart attack or myocardial infarction is chest pain or discomfort. The pain may feel like tightness, squeezing, or pressure in the chest area. It may also radiate to the arms, neck, jaw, back, or stomach.

This chest pain may come and go and can last for a few minutes or longer. Ignoring persistent or severe chest pain can be life-threatening.

2. Shortness of Breath

Feeling out of breath, even with minimal physical exertion or at rest, can be a sign of a heart attack. Shortness of breath may be accompanied by other symptoms such as chest pain, lightheadedness, or sweating.

If you experience unexplained shortness of breath, it is crucial to seek immediate medical attention.

3. Profuse Sweating

Sudden and excessive sweating, without any apparent cause such as exercise or heat, can indicate an impending heart attack or myocardial infarction.

This cold, clammy sweat is often different from regular perspiration and can be accompanied by other symptoms like chest pain or discomfort.

4. Nausea and Vomiting

During a heart attack or myocardial infarction, some people may experience nausea or vomiting. These symptoms can be particularly common among women.

Nausea and vomiting, along with other cardiac symptoms, should never be taken lightly and should prompt immediate medical attention.

5. Dizziness or Lightheadedness

Feeling dizzy or lightheaded, especially when accompanied by chest pain or shortness of breath, can indicate a heart attack or myocardial infarction. These symptoms may occur suddenly and can be a sign of poor blood flow to the heart or brain.

If you feel dizzy or lightheaded for no apparent reason, it is important to seek medical help promptly.

6. Weakness or Fatigue

Unexplained weakness or fatigue, even after getting enough rest, can be a warning sign of a heart attack or myocardial infarction.

Feeling excessively tired or having a decreased ability to perform routine activities should not be ignored and may signal a serious underlying problem.

7. Sudden Numbness or Weakness on One Side of the Body

In the case of cerebral infarction or stroke, sudden numbness or weakness on one side of the body, including the face, arm, or leg, is a classic warning sign.

The affected individual may experience difficulty speaking, understanding speech, or coordinating movements. Immediate medical attention is crucial in stroke cases to minimize potential brain damage.

8. Sudden Vision Problems

If you suddenly experience blurred vision, double vision, or loss of vision in one or both eyes, it could be a sign of a stroke or cerebral infarction.

Vision problems that arise suddenly and without any apparent cause should never be ignored and require immediate medical attention.

9. Severe Headache

A sudden and severe headache, often described as the worst headache of one’s life, can indicate a cerebral infarction or hemorrhagic stroke.

If the headache is accompanied by other stroke symptoms like numbness, weakness, vision problems, or difficulty speaking, it is essential to seek emergency medical help without delay.

10. Confusion or Mental Changes

Sudden confusion, disorientation, difficulty speaking, or understanding others can indicate a stroke or cerebral infarction. These mental changes can occur alongside other stroke symptoms or on their own.

If you or someone around you experiences sudden mental changes, it is crucial to seek immediate medical attention.
