Which of the following are signs of a heart attack?

• A. Trouble breathing
• B. Chest pain
• C. Loss of consciousness
• D. All of the above

Answer: (D)

A heart attack happens when the heart isn’t getting enough oxygen, and the body often shows a mix of warning signs rather than one single symptom. Chest pain or pressure is the most familiar sign, but trouble breathing can also occur because the heart isn’t pumping effectively. In some cases, people may feel lightheaded or even lose consciousness as blood flow to the brain drops. Because these symptoms can vary and can appear together, recognizing all of these possibilities is important. If you notice chest discomfort, difficulty breathing, or fainting, seek emergency help immediately and provide first aid as needed. If trained, you can follow responder steps like keeping the person resting, loosening tight clothing, monitoring consciousness, and starting CPR or using an AED if the person becomes unresponsive.
