“If you’re not sure, get it checked out,” advises Charles Chambers, MD, director of the Cardiac Catheterization Laboratory at Penn State Hershey Heart and Vascular Institute. This is especially true if you are 60 or older, obese, diabetic, have high cholesterol, or have high blood pressure.
You should be aware of these indicators.

Chest discomfort. It is the most prevalent early indicator of a heart ᴀᴛᴛᴀᴄᴋ. Remember that if you have a clogged artery or are having a heart ᴀᴛᴛᴀᴄᴋ, you may feel chest pain, tightness, or pressure.
The experience often lasts longer than a few minutes. Be aware that it may occur while you are sleeping or doing anything physical.
Symptoms include nausea, irritable bowel syndrome, heartburn, and stomach pain. During a heart ᴀᴛᴛᴀᴄᴋ, some people experience the following symptoms. Some may even vomit. Women are more likely than men to report this symptom.
So, if you’re feeling this way and are at risk for cardiac problems, see a doctor to figure out what’s happening, especially if you have any of the other symptoms listed below.
Throat and jaw discomfort. It is doubtful that a heart problem is causing your throat or jaw pain. Muscular problems, a cold, or sinus issues are more likely to be the cause of the problem.
If you feel pain or pressure in the center of your chest that spreads to your throat or jaw, you may be having a heart attack.
Symptoms include arm pain, dizziness or lightheadedness, fatigue, excessive snoring, perspiration, swelling of the legs, feet, and ankles, and irregular heartbeat are just a few of the many signs of heart issues to be aware of.
