The LA Times is reporting that, lo and behold, exercise raises your chances of a "cardiac event" in the short term, but pushes down the chances in the long term.
This is pretty much common knowledge already; the little kicker is that they threw in sex in the report just attracts the headlines. But yes, exercise increases stress on your heart a little bit - and and that stress, in the long run, causes your heart to make positive adaptations in order to sustain that level of effort in the future. Make you heart work harder and you suffer a short-term risk of "cardiac event" but then get a stronger heart, more able to resist the same strain in the long term. This is not news - the heart is a muscle too! It needs exercise to stay healthy and handle threats.
