Better way to identify people at high risk of a heart attack

I found a hopeful article on BBC.

A new way of scanning which can identify people at  high risk of a heart attack was invented.  The heart attack is one serious cause of death in the world, and more than 100,000 people suffer from it each year in the UK. However, the new scanning would improve these problems.

Sometimes technology lead us to worse conditions accidentally, but the new way of scanning the heart surely help us. I am really amazed at superior power of the technology which makes our everyday life much better these days. On the other hand, I think it is really unhealthy that we tend to rely on the technology too much, and in fact, it causes a lot of lifestyle-related illnesses. Some scientists say that heart attack can be caused by bad lifestyle, so it is one of the lifestyle-relatd illness. Reflecting on the way I live, I can easily see that it probably bring me a heart attack or another life-related illness. In short, we should not live depend heavily on the technology although it is useful, practical and reliable so that we can be much more healthy. (137 words)
