As a daughter living with two senior-aged parents, one who has been suffering from high blood pressure for years, I am very aware that I may one day have to deal with their flailing health.
I read that heart attack is a silent killer and my father, who has high blood pressure is has a high risk of a stroke or heart attack. Inside Cardiac Arrest is very informative site on heart health and it shows the differences between a heart attack and a Sudden Cardiac Arrest.
To prevent Sudden Cardiac Arrest, a heart pacer may have to be embedded to control irregular heartbeat. This was what my cousin sister had to be treated for when she was only a teenager.
If you would like to learn more about Sudden Cardiac Arrest (SCA), do watch the video and read up on it on Inside Cardiac Arrest.
