How our body warns us days before a heart attack

I think the information (These 4 Things Happen Right Before a Heart Attack)
in form of  a video by Dr Crandall will help immensely the people suffering from heart problems or are at the risk of it. As we think heart attack is a silent killer.

Despite what we may believe, heart attacks rarely happen without any notice.
Body may be trying to warn you of an impending heart attack for days, weeks, perhaps even a month or two before it occurs. Unfortunately, by the time you actually recognize you’re suffering a heart attack; it could be too late to prevent death or debilitating heart damage. Much can be done to prevent death and damages if symptoms are recognized well in time.
Statistics show a clear link between a delay in heart attack treatment and death or disability. That’s why it’s essential to know exactly what your heart is trying to tell you with warning signs.
