Heart attacks occur when there is a lack of blood flow to the heart. This can lead to heart muscle damage and/or death due to a lack of oxygen as oxygen is transported in the blood.
The damaged muscle tissue may be replaced with scar tissue, which can have permanent effects. Heart Attacks are most commonly caused by CAD and are linked to other conditions such as Congestive Heart Failure or CHF.
Symptoms of a heart attack include:
• Chest pain or discomfort
• Upper body pain in the arms, back, neck, or jaw
• Stomach pain and nausea
• Shortness of breath
• Fainting or lightheadedness
• Cold sweats
