Erectile dysfunction is a warning sign that the heart may be having problems. Don't take it lightly.

Occasionally, your performance is not optimal. Most men handle it by saying: No big deal, just tired.
But few people know that ED is an early warning sign of cardiovascular disease, appearing on average 3 to 5 years before a heart attack.
Erection depends on the health of blood vessel endothelium, which is also the first tissue to show problems in the cardiovascular system.
The penile artery diameter is 1-2mm, while the coronary artery diameter is 3-4mm. The thinner the vessel, the earlier the warning signal.
