This mortality is niitrates lower sildenafil the sildenafil cardiovascular mortality expected, which is deaths per week per each sildenafil men It is important to emphasize that these encouraging data do not apply to patients, who, using or not using sildenafil, increase their circulatory and metabolic overload beyond their usual limits, as may happen in extramarital coitus or in coitus after excessive ingestion of food and alcoholic beverages; d risk assessment: The coadministration of one of these drugs may lead to competitive inhibition of the metabolism of sildenafil. This dysfunction occurs mainly among individuals with coronary artery disease, after episodes of acute ischemic syndrome, hypertensive patients underpharmacologic treatment, and among patients with heart failure.

Although firm data are lacking, pre-Viagra treadmill test to assess for the presence of stress-induced ischemia can be helpful. Sildenafil leads to relaxation of smooth muscle of penile arteries and trabeculae surrounding the sinusoidal spaces, resulting in a greater engorgement of cavernous body.
