What to do:
If you feel this type of pressure or burning, call emergency services immediately. Do not attempt to drive or wait for it to "pass."
A quick diagnosis can mean the difference between life and death.
Shortness of breath or difficulty breathing
Another common—and often underestimated—sign is the feeling that not enough air is getting in, even when at rest or doing light activities.
This happens because when the heart fails, it cannot pump enough oxygenated blood, and the body interprets this as a lack of air.
This symptom can appear days before the heart attack, especially at night or when going to bed.
What to do:
If you notice that you are short of breath for no apparent reason, especially if it is accompanied by tiredness or chest pressure, seek immediate medical attention.
Extreme or unusual tiredness
One of the most silent signs, especially in women, is sudden and unexplained fatigue.
If you suddenly find it difficult to perform simple activities—such as climbing stairs, cooking, or walking short distances—and feel low on energy even though you have slept well, your body may be indicating a lack of oxygen in your muscles and vital organs.
What to do:
Constant fatigue should not be considered normal. If it occurs along with other symptoms (dizziness, shortness of breath, chest tightness), consult a doctor as soon as possible.
Dizziness, nausea, or cold sweats
When blood flow to the brain decreases, you may feel dizzy, nauseous, or experience excessive cold sweating.
Many people mistake this for a simple drop in blood pressure or stress, but if it occurs suddenly and is accompanied by chest discomfort or paleness, it could be a warning sign of an impending heart attack.
What to do:
If you experience these symptoms unexpectedly, sit down, try to stay calm, and seek medical help. Do not attempt to continue with your activities.
Pain or numbness in the arm, back, or jaw:
During a heart attack, the pain is not always located in the chest.
It can radiate to the left arm (sometimes the right), upper back, neck, or even the jaw.
