Which of the following is a sign of a heart attack?

Chest pain or discomfort is a classic and well-recognized sign of a heart attack, often referred to as angina or myocardial infarction. This discomfort can present as pressure, squeezing, fullness, or pain in the center or left side of the chest. It may also radiate to the shoulders, neck, arms, back, teeth, or jaw. Recognizing this symptom is crucial, as it is one of the main warnings indicating a potential blockage in the coronary arteries, which can lead to heart muscle damage if not addressed promptly.

In contrast, while increased heart rate, fever, chills, nausea, and vomiting can be associated with various medical conditions, they are not definitive signs of a heart attack. Increased heart rate can occur during stress or anxiety, and fever or chills might suggest an infection, while nausea and vomiting can result from a myriad of causes unrelated to cardiac issues. Understanding the specific symptoms of a heart attack is essential for timely intervention and improving outcomes.
