As far as I can tell this study didn't look at any association with cardiovascular health outcomes, but rather with a "CVH score" that incorporates various risk factors. Unless I'm missing something, the bottom line seems to be that non-dog-owners have a CVH score of 9, while dog owners have a CVH score of 10 (despite being the group most likely to smoke). I have no idea how that translates into a difference in probability/rate/severity of cardiovascular events.
