Sudden Cardiac Arrest 
SCA =17% of all US deaths

Heart Attack 
24% of all US deaths

2 required symptoms: Unconscious and no pulse is felt - heart is fibrillating, stopped (asystole), or extremely slow

12 possible symptoms, including pressure or pain in chest, pain spreading to shoulders/arm, shortness of breath. Heart Attack victim is almost always conscious

Death typically occurs in 10 minutes. SCA usually defined as death within 1 hr of symptom onset

Death may result if there is no emergency medical care

Apply CPR to keep some blood flowing to brain while waiting for defibrillation to arrive. Note: CPR is only useful in those regions which have emergency medical services.

No CPR needed, the heart is still pumping

Most SCAs will be stopped with defibrillation, –which "reboots" the heart without lasting damage

Bring patient to hospital ASAP – to reduce and perhaps reverse the amount of heart muscle death.

SCA victims are unconscious and unable to call for help.  The 40% of SCAs victims who are unwitnessed virtually always die.

Heart Attack victim might call for emergency medical help, but typically bystanders call.

SCA is often totally unexpected

Heart Attacks are often proceeded by warning signs for months.

SCA is an electrical malfunction without long-term damage

Mechanical malfunction: typically clogged or burst arteries

SCA will rarely cause a Heart Attack

A Heart Attack may trigger a SCA

Survival from SCA with Skyaid is expected to be at least  70%. Survival from SCA is only just 10% for those areas with typical slow emergency services, and even less in those areas without emergency services

Skyaid will reduce or perhaps damage and death from heart attacks
