As a medical professional, I can confirm that the symptoms of a heart attack can indeed come and go. These symptoms are often a result of reduced blood flow to the heart muscle. It's important to recognize that heart attacks don't always present with the classic textbook symptoms. Some individuals may experience discomfort in the center of the chest that can last for a few minutes and then subside, only to return later. This pattern can be misleading and lead to underestimating the severity of the situation. In addition to chest discomfort, symptoms can manifest in various other ways, such as pain or discomfort radiating to one or both arms, the back, neck, jaw, or even the stomach.
