Anxiety Attack vs. Heart Attack
People who have panic attacks commonly fear they are having a heart attack. This makes the panic anxiety worse. Some symptoms of panic attack are also experienced during a heart attack so it is understandable that people may mix them up.

Anxiety Attack vs. Heart Attack
Heart Attack Panic Attack
Pain May or may not be present If present, the pain is often described as a crushing feeling (like someone standing on the chest) The pain is usually located in the central chest and may extend to the left arm, back and neck Pain, if present, is not usually made worse by breathing or by pressing on the chest Pain, if present, is usually persistent and lasts longer than 5-10 minutes
Any pain is usually described as ‘sharp’ The pain tends to be localized over the heart Pain is usually made worse by breathing in and out and by pressure on the centre of the chest Pain usually disappears within about 5-10 minutes
Tingling Tingling, if present, is usually in the left arm Tingling is usually present all over the body
Vomiting Common Nausea may be present but vomiting is less common
Breathing A Heart Attack does not cause you to breathe too quickly or too deeply (hyperventilation) – panic does. With a heart attack you may feel a little short of breath. It is possible however, to have a heart attack and then start panicking. In this case, hyperventilation is a symptom of panic not of the heart attack
Breathing too quickly or too deeply (hyperventilation) is an extremely common panic response which precedes most panic attacks

Like an elephant sitting on my chestOften radiates to shoulders, arms, upper abdomen and back.

Anatomy of a Heart Attack
The Coronary Arteries nourish the heartPlaque build-up narrows these arteries (arteriosclerosis)Artery occludes meaning decreased blood flow to an area of the heartInsufficient blood supply results in oxygen deprivation, this causes the symptoms of chest pain and ultimately myocardial infarctions

About Aspirin
Aspirin (ASA) is acetylsalicylic acid and falls into a class called non-steroidal anti-inflammatory drugs (NSAIDS)Due to aspirin’s blood thinning effect it can reduce coronary heart disease events and strokesAspirin is not benign

Benefits of Aspirin
Living up to its reputation as a 'wonder drug', aspirin has been shown in clinical studies to reduce the rate of heart attacks, strokes and related deaths. The ability of aspirin to prevent blood from clotting (makes the cells 'less sticky') prevents these events from happening. Aspirin also helps even if a heart attack or stroke does occur and often reduces the severity of the event.

Surviving a Cardiac Arrest
5% survive nationally5-10% survive locally
NOTE: not all heart attacks cause cardiac arrest
![Page 25: Chest Pain The Evolution of a Heart Attack Presented by: Scott G. Popowich, CCEMT-P EMS Coordinator Kodak Rochester Medical Services.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ce05503460f949aaa8f/html5/thumbnails/25.jpg)
Defibrillation
When the heart stops beating, chances of survival decrease by 10% for each minute that passes. Survival rates are higher when a defibrillator is used right away. Irreversible brain damage can begin in just 4 minutes!
