A heart attack, medically known as a myocardial infarction, occurs when the blood flow to the heart is blocked, leading to damage or death of heart muscle cells. It is a life-threatening emergency that requires immediate medical attention.

While heart attacks can happen suddenly without warning, most start slowly, with milder symptoms that may be easy to overlook.

1. Chest Pain or Discomfort

The most common symptom of a heart attack is chest pain or discomfort. This can feel like pressure, squeezing, fullness, or pain in the center of the chest. The discomfort may last for a few minutes or come and go.

It is important to note that chest pain can vary from person to person, with some experiencing intense pain and others feeling only mild discomfort.

2. Shortness of Breath

Feeling breathless or experiencing difficulty in breathing can also be a symptom of a heart attack. This occurs due to the heart’s reduced ability to pump blood efficiently, causing the lungs to receive insufficient oxygen.

Shortness of breath can happen with or without chest pain and may worsen with physical activity or even at rest.

3. Fatigue

Unusual fatigue or extreme exhaustion can be an early warning sign of a heart attack. The heart’s reduced ability to pump blood can make everyday activities feel exhausting.

Fatigue due to a heart attack is typically more pronounced than normal tiredness and may be accompanied by other symptoms such as chest discomfort or shortness of breath.

4. Dizziness or Lightheadedness

Feeling dizzy or lightheaded can be a result of inadequate blood flow to the brain, which can occur during a heart attack. This symptom is often overlooked or attributed to other causes, such as dehydration or low blood pressure.

If dizziness is accompanied by chest pain, shortness of breath, or any other heart attack symptom, it should not be ignored.

5. Nausea or Vomiting

Some people experience nausea, vomiting, or indigestion-like symptoms before or during a heart attack. These gastrointestinal symptoms can be accompanied by other warning signs, such as chest pain and shortness of breath.

It is essential to pay attention to any unusual or unexplained digestive discomfort, especially if it is accompanied by other heart attack symptoms.

6. Cold Sweats

Sudden, unexplained episodes of cold sweats can also be an indicator of a heart attack. These sweats may feel different from normal sweating due to exercise or heat and are often accompanied by other symptoms such as chest pain and shortness of breath.

If you experience cold sweats along with any other signs of a heart attack, seek immediate medical attention.

7. Arm Pain or Discomfort

While chest pain is the most common symptom of a heart attack, discomfort in the arms, particularly the left arm, can also be an indication. The pain may radiate from the chest to the arm or start directly in the arm without chest pain.

Arm pain or discomfort is frequently described as aching, numbness, or a tingling sensation.

It is important to note that not everyone experiences the same symptoms during a heart attack. Some individuals may have atypical symptoms or none at all, especially women, older adults, and those with diabetes.

In some cases, the symptoms may be mistaken for indigestion, muscle strain, or anxiety, delaying prompt medical attention.

If you suspect a heart attack, it is crucial to act quickly. Call emergency services immediately and seek medical help. Remember, every minute matters when it comes to treating a heart attack and preventing further damage to the heart.
