What is a key symptom of a heart attack?

A key symptom of a heart attack is dizziness or light-headedness. This occurs because the heart may be struggling to pump blood effectively, which can lead to a decrease in blood flow to the brain. When the brain doesn’t receive enough oxygenated blood, it can cause sensations of dizziness or faintness. This symptom can be accompanied by other indicators of a heart attack, such as chest pain, shortness of breath, or discomfort in the arms, back, neck, jaw, or stomach. Recognizing these signs is essential for prompt medical attention, which can significantly impact the outcome in a heart attack situation.

Other options, such as a rash on the arms or itchiness in the throat, are typically associated with allergic reactions or other medical conditions rather than heart attacks. A feeling of extreme calmness is also not indicative of a heart attack and contrasts sharply with the feelings of anxiety or distress that can accompany this medical emergency. Understanding these key symptoms can help individuals act quickly and seek help when needed.
