I don't know that it is heartless, but it is worthless.
They are trying for the shock tactics but a lot of studies have shown that the worse you make something appear, the less people listen to it as they don't think it will apply to them.
There is no useful information in that ad. No information about how to recognise a heart attack, who could be a victim, not even any information of how to go about getting yourself checked out. It's what I see as a soppy ad and it's written by someone who is driven by emotions and not logic. It doesn't fly with me.
PS And they need a better voice over. Some one with a clearer voice and message.
