When the heart stops, it stops pumping blood throughout the body. All brain activity is believed to cease by about three to four minutes from the time the heart stops due to lack of oxygen

Can you have a heart attack without cardiac arrest?

D
Dr. Aman Priya KhannaExpert
Yes, a person can get a heart attack without cardiac arrest. Heart attacks occur due to a blockage in the coronary arteries. However, heart attacks can sometimes lead to sudden cardiac arrest.

How do I know if I have a heart attack or just indigestion?

HexaHealth TeamExpert

If you experience belching, bloating, or burning sensation, it’s probably indigestion and gastric problems. But if you’re going through heart palpitation, discomfort in the left side or centre of the chest, cold sweat, shortness of breath, pain in the jaw, neck, shoulder, arm, or stomach, unexplained anxiety, or fast heartbeat, it might be a heart attack. These are the main difference between gas pain and heart attack. 

What time of day do most heart attacks occur?

HexaHealth TeamExpert
Most heart attacks occur in the morning, between 6 am and noon. This is likely due to increased stress as people rush around to prepare for work or school. Some studies have found that blood pressure tends to be higher in the mornings, which could also increase the risk of a heart attack.
