When the heart stops, the brain and other vital organs stop receiving oxygen. If not treated, death can ensue in minutes.
Symptoms: The sypmtoms of a cardiac arrest include a person suddenly collapsing, the loss of consciousness, the absence of a pulse, and a person not breathing.
•Previous heart attack - 75% of SCA cases are linked to a previous heart attack
•Coronary artery disease
•Family history – genetic reasons put even younger populations at risk
What is a heart attack?
A heart attack occurs when a blood clot blocks blood flow to the heart, causing blockage of an artery. Again, without blood flow, the body's vital organs are starved of oxygen, which can lead to death.
A heart attack is easier to spot because it comes with prior symptoms, like tightness of the chest or chest pain, a sharp ache in the left arm, fatigue, lightheadedness and an abnormal heartbeat.
Symptoms: The symptoms of a heart attack aren't always obvious but they include discomfort in the left side of the chest/upper abdomen, shortness of breath from any from any form of exertion, a cold sweat, and vomiting/nausea.
•High blood pressure (hypertension)
•High serum cholesterol
•Family history of coronary disease
•Stress and obesity
Cardiac arrest vs heart attack: How are they different?
A cardiac arrest is sudden, unexpected and occurs when your heart stops pumping blood to your body. A heart attack occurs when blood flow to the heart is blocked.
