There is evidence now that men who have heart heart disease and erectile dysfunction die sooner in life than those men who just have heart disease. Boy, can life deal us guys any worse a hand? In effect, those patients who need drugs like Viagra may have widespread cardiac disease. This came out in the journal Circulation. The author's conclusion to the study is way too long and filled with boring facts. Let me summarize in a more palatable way: Just because ED drugs work on hardening of the penis doesn't mean they do anything for hardening of the arteries.
