Heart attacks, or myocardial infarctions, are a leading cause of death worldwide. Recognizing the early warning signs can be crucial for prompt medical intervention and potentially saving lives. By understanding these signs and taking immediate action, individuals can help mitigate the potential risks associated with a heart attack. Below are the five common early warning signs of a heart attack:

Chest Discomfort or Pain

One of the most recognizable warning signs of a heart attack is chest discomfort or pain, according to Mayo Clinic. The sensation is often described as a tightness, pressure, squeezing, or fullness in the chest. This discomfort may come and go or persist for several minutes. It is important to note that not all individuals experience severe chest pain during a heart attack, and some may even mistake it for indigestion or muscle soreness.

Shortness of Breath

Shortness of breath is another common symptom that may precede or accompany a heart attack. Individuals may feel breathless, as though they cannot get enough air, even during light physical activity or at rest. The American Heart Association noted that this breathlessness can be accompanied by other symptoms such as chest discomfort, lightheadedness, or sweating. It is crucial not to ignore persistent or sudden-onset shortness of breath, as it can indicate a potential cardiac emergency.

Discomfort or Pain in Other Upper Body Areas

During a heart attack, discomfort or pain may extend beyond the chest and radiate to other areas of the upper body, per Cleveland Clinic. This can include the arms (particularly the left arm), back, neck, jaw, or stomach. The sensation may feel like pressure, heaviness, or aching. If you experience unexplained discomfort or pain in these areas, it is important to consider it as a potential warning sign of a heart attack.

Profuse Sweating

Sudden, unexplained sweating, often accompanied by other symptoms, can be an early warning sign of a heart attack. McLeod Health explained that this excessive sweating is not attributable to external factors such as physical activity or a warm environment. If you notice unexplained and profuse sweating, particularly if it coincides with other symptoms, it is essential to take it seriously and seek immediate medical attention.

Nausea and Lightheadedness

Feeling nauseous, dizzy, or lightheaded can be a sign of a heart attack, especially in combination with other symptoms. Some individuals may experience a sense of impending doom or anxiety. It is crucial not to dismiss these feelings as unrelated or insignificant, as they can be indicative of a cardiac event.

What to Do if You Suspect a Heart Attack

If you experience any of the aforementioned warning signs or suspect a heart attack, it is crucial to act promptly. Here are important steps to take, according to experts:


  • Call Emergency Services: Dial the emergency number in your country (e.g., 911 in the United States) without delay. It is essential to seek immediate medical attention for a suspected heart attack.

  • Stop Activity: Cease any physical activity and rest, as continued exertion can strain the heart further.

  • Chew Aspirin: If you are not allergic to aspirin and have access to it, chew a regular aspirin (325 mg) while awaiting medical assistance. Aspirin can help prevent further blood clotting.

  • Stay Calm and Await Medical Help: Try to remain as calm as possible while waiting for emergency medical services to arrive. Avoid driving yourself to the hospital, as emergency medical personnel are equipped to handle cardiac emergencies effectively.

Recognizing the early warning signs of a heart attack is crucial for prompt medical intervention. Symptoms such as chest discomfort, shortness of breath, upper body pain, profuse sweating, nausea, and lightheadedness can indicate a potential cardiac emergency. If you experience any of these warning signs, it is important to call emergency services immediately and seek medical attention. Remember, every minute matters in minimizing the potential damage caused by a heart attack.
