ED drugs are safe for men with healthy hearts, but those with heart disease should take extra measures, and some guys should never take them. Their effect on arteries is the issue. Because all arteries, not only those in the penis, produce nitric oxide, any artery can widen in response to Viagra, Levitra, or Cialis, lowering blood pressure by 5-8 mmHg for a brief period of time, even in otherwise healthy men.

When the blood supply to a section of the heart muscle is blocked, a heart attack, also known as a myocardial infarction, occurs. Chest pain, weakness, shortness of breath, and pain or discomfort in the back, arms, or shoulders are all classic signs of a heart attack.

Viagra is a vasodilator, which means it helps blood vessels and arteries to open up. Men taking Viagra have been reported to suffer from heart attacks, strokes, arrhythmias, and even death.

The performance of sexual activity was more probable than the use of Viagra to cause heart attacks.

Although there is no definitive evidence linking Viagra heart attacks, men with established heart issues or who are taking heart medications should avoid or use erectile dysfunction therapies with caution.
