Also, it is important to remember that there are psychogenic issues such as performance-related issues, traumatic past experiences, relationship problems, anxiety, depression and stress that can certainly cause or be considered a comorbid condition contributing to ED. Bullet

The role of the endothelium in ED has been noted for a number of years and the overlapping of ED and other conditions, especially coronary heart disease, CVD, affecting endothelial function/dysfunction, is clearly present. The endothelial cell is now known to affect vascular tone and impact the process of atherosclerosis, and impacting ED, CVD and peripheral vascular disease.16.

The role of the endothelium in erectile function became clearer with the observation that the phosphodiesterase type 5 (PDE5) inhibitor, sildenafil, enhanced erectile function.

Erection occurs with the release of nitric oxide (NO) from the vascular endothelial cells.17 The reduction in endothelial cell production of NO results in the negative impact on the smooth muscles in the corporal bodies and results in less relaxation of the smooth muscle cells with decrease in blood supply and resulting ED.

A similar phenomenon is well known to impact the coronary arterial system resulting in CVD. It is important to understand that ED is frequently, if not usually, directly related to endothelial dysfunction, and that the release of NO by the vasculature of the penile arteries is directly related to the function of intact, healthy endothelium.

In the face of endothelial dysfunction, the process of erection fails to occur in a normal fashion.16.

The association of ED, CVD and endothelial dysfunction. The pathogenesis of organic ED is related to dysfunction of the endothelium.

Endothelial cells can become injured through a variety of mechanisms, most of which cause oxidative stress on the tissues.

Many of these causes of oxidative stress are related to lifestyle issues which lead to hypertension, diabetes and dyslipidaemia (figure 1). Endothelial cell dysfunction results in reduction of endothelium-dependent vasorelaxation as well as increased adhesion of leukocytes to the endothelium. Endothelial cell injury then leads to a variety of sequelae, including ED, other types of vasoconstriction, atherosclerosis and thrombus formation.18.

The association of CVD and ED was noted in 1997 as one analysed the results of the MMAS. In this landmark study, 1709 men aged 40–70 years were enrolled between 1987 and 1989.

A follow-up some 10 years later revealed a striking relationship between ED and CVD.

In this study, it became clear that the risk factors for ED were very similar to those of CVD, such as diabetes mellitus, smoking and dyslipidaemia.18.

Since endothelial dysfunction, CVD and ED are closely associated in epidemiological studies, the question for clinicians is whether to recommend the man presenting with ED undergo a cardiovascular (CV) evaluation.

Clearly, based on numerous studies, ED can be considered at least a ‘marker’ for possible further vascular disease or CVD.15 In their report, Vlachopoulos and coworkers make the point that the man presenting with ED, the clinician, is offered an opportunity to attempt to improve the health of the man by addressing lifestyle modification, and consider further vascular evaluation owing to the clear relationship between endothelial dysfunction, ED and CVD.19. Watts and coworkers, in their review article, make several points about this ED/CAD nexus.

Endothelial dysfunction is present in both CVD and ED, and is linked through the NO mechanism. The authors note that PDE5 inhibitors improve endothelial function and have a salutary effect on both CVD and ED.

Both ED and cardiac disease respond to modifications in lifestyle as well as pharmacologic manipulation. These authors also report that the presence of ED gives the clinician an opportunity to assess CVD and prevention as well.20.

Due to the fact that ED and CVD share many of the same risk factors, it is not surprising that there is a high incidence of ED in men who present with CVD.

A study by Montorsi et al found that ED was present in roughly 50% of patients with acute chest pain and confirmed CAD on angiography.21. In buy viagra cvs this study, ED proceeded CVD in almost 70% of cases. Similarly, many men with ED have been found to have pre-existing CVD. A study by Vlachopoulos et al evaluated the incidence of asymptomatic CVD in 50 men with ED.22 These authors found that 19% of men with ED had asymptomatic CVD.

Similarly, Mulhall and colleagues found that 20% of men presenting with ED and vascular insufficiency on penile duplex had asymptomatic CVD.23.

These findings suggest that patients who present with ED and CV risk factors should be evaluated for silent CVD and should undergo a thorough CV evaluation. Men with new onset ED

and

A meta-analysis of 36 744 men with ED in 12 prospective cohort studies found that the presence of ED significantly increased the risk of CVD, CAD, stroke and all-cause mortality, and the presence of ED was an independent risk factor for CVD.

Ponholzer et al found that men with moderate to severe ED had a 65% increased relative risk for developing symptomatic CAD compared with men who did not have ED.26.

The Prostate Cancer Prevention Trial was a landmark study by Thompson et al that prospectively assessed the time to developing CVD after the diagnosis of ED. There were 4247 men with no ED at study entry; 2420 developed incident ED (defined as the first report of ED of any grade) over 5 years. Those men that developed ED had a 1.45-fold higher probability of experiencing a CV event compared with men who did not develop ED.27.

The severity of ED has been correlated with the extent of CVD.

Banks et al reported that the risk of future CV events increased progressively according to ED severity.28 This was shown in both men with and without known CVD at baseline and after controlling for confounders.

Solomon and colleagues found an inverse correlation between international index of erectile function (IIEF) scores and plaque burden seen on coronary angiography.29 In addition, Yaman et al demonstrated a significant correlation between ED severity on IIEF questionnaires and coronary artery calcification.30.

On the horizon is gene therapy that would deliver genes that produce products or proteins that may not be functioning properly in the penile tissue of men with ED. Replacement of these proteins may result in improvement in erectile function. Experimental animal models have demonstrated improvement in erectile function with gene therapy.

Human studies may also demonstrate success with this therapy. Gene therapy may take a long time for regulatory approval and public acceptance.

The first stem cell study for the treatment of ED was published in 2004. At this time, there is a total of 36 published basic studies assessing stem cell therapy for ED, with two clinical trials. The mechanism of action of stem cells is to generate angiogenesis with subsequent increase in cavernosal smooth muscle cells within the corporal bodies.46.

Another

The purpose is to stimulate neovascularisation to the corporal bodies with improvement in penile blood flow and endothelial function.

The use of low-intensity shock wave lithotripsy may convert PDE5 inhibitor non-responders to responders.47.

Finally, there are NO-releasing polymers that are capable of delivering NO in a pharmacologically useful way.

Such compounds include compounds that release NO upon being metabolised and compounds that release NO spontaneously in aqueous solution. Initial animal studies suggest that cavernosal injections of NO polymers can significantly improve erectile function.48. Many areas in the field of ED remain ripe for further investigation: Can we develop a simple yet accurate method to distinguish organic from psychogenic ED? What are truly the norms for testosterone levels in men and could we better determine which might actually benefit, and thus, should receive TRT? What is the future of stem-cell therapy in the treatment of men with ED.

Nearly every primary care physician, internist and geriatrician will be treating men with ED. The recent shift in the management and evaluation of ED, with primary care physicians replacing urologists in the forefront of ED diagnosis and therapy, has been a welcome and timely change. It is likely to improve ED management and benefit a large number of men, particularly in terms of recognising ED as a sentinel of vascular disease.

Please answer true and false to the below statements. Men in their 40s with erectile dysfunction (ED) compared with men without a history of ED have an increased risk of developing cardiovascular disease (CVD) in 5 years.

Men presenting with ED should have consideration for a cardiovascular work-up as significant numbers of these men have occult or asymptomatic heart or vascular disease.

Endothelial dysfunction is more common in men with ED than in men with CVD.

The most likely explanation for men developing ED prior to developing CVD is that the penile arteries are much smaller than the coronary arteries and the smaller penile arteries are likely to be occluded before the coronary arteries are significantly narrowed and become symptomatic.

All men receiving testosterone replacement need to have periodic measurement of haemoglobin and haematocrit to monitor for erythrocytosis.

False (both groups have endothelial dysfunction) When Viagra Doesn’t Work. Erectile dysfunction is a common occurrence in men with diabetes.

The incidence of erectile dysfunction increases progressively with age, from 5% in men age 20 to 75% in men over age 65.

The cause of erectile dysfunction in men with diabetes is usually related to a decrease in the blood supply to the penis as well as to injury to the nerves that are responsible for the erection mechanism.

A decrease in testosterone production has also been identified as the cause in some men with diabetes. Since 1998, when sildenafil (brand name Viagra) first came on the market, oral therapy has been successfully used to treat erectile dysfunction in many men with diabetes. (Sildenafil was followed in 2003 by the drugs tadalafil [Cialis], vardenafil [Levitra] and avanafil [Stendra], which work in much the same way.) Some 50% of men with Type 1 diabetes who try the drugs report improved erections, and some 60% men with Type 2 diabetes do, too.

However, that leaves a large percentage of men with diabetes and erectile dysfunction who do not respond to therapy with one of these pills.

This article takes a look at what can be done to treat those men who do not respond to oral therapy. Why therapy fails There are a number of reasons a man may not achieve the desired result from an oral erectile dysfunction drug. In some cases, a man may experience drug side effects severe enough to outweigh any potential benefit of taking the drug.

Possible side effects of these drugs include headache, facial flushing, nasal congestion, and transient abnormal vision.

(In October 2007, the FDA added a warning about sudden hearing loss to the package labels of oral erectile dysfunction drugs.

While it’s not absolutely clear that the drugs can cause sudden hearing loss, a number of cases have been reported in men within hours or days of taking one of the drugs.) — Learn More About Complications & Prevention >> Another common reason for failures of oral therapy is the absence of sexual or genital stimulation prior to attempting sexual intercourse.

These medicines facilitate an erection by increasing blood flow to the penis, but they do not act as an aphrodisiac or as an initiator of the erection.

A man who is not “in the mood” or does not have adequate physical stimulation will not respond with an erection. Yet another reason for the drugs not to work as intended is the consumption of a high-fat meal before or along with taking the drug.

The fat in such a meal can decrease absorption of the medicine from the gastrointestinal tract.

It’s also possible for anxiety about intercourse after a prolonged period of abstinence, fear of side effects, or unaddressed psychological issues such as guilt or religious concerns about engaging in sexual intimacy to interfere with the ability to

get

In many of these cases, a discussion between the physician, the man with erectile dysfunction, and possibly his partner can help to resolve the issues leading to treatment failure. For men who experience severe side effects, can’t take the drugs for other reasons (such as taking medicines such as nitroglycerin), or don’t respond in spite of further education on the correct use of the drugs, there are other treatment options that can help most men remain sexually active. Using oral drugs properly For oral erectile dysfunction medicines to work as desired, they must be used properly in the first place.

This means taking the medicine 30–45 minutes before engaging in sexual intimacy; taking the drug on an empty stomach or at least avoiding a heavy or high-fat meal before taking the drug (this is especially important when using sildenafil); and engaging in adequate genital stimulation before attempting intercourse. Drinking small amounts of alcohol (one to two drinks) should not compromise the effectiveness of erectile dysfunction medicines, but larger amounts of alcohol can diminish a man’s ability to have an erection. A man needs to try the medicine at least four times before he concludes that it doesn’t work for him.

It is unlikely that a man with diabetes who has other medical problems

such

Some doctors prefer to start a man on the lowest dose of an oral medicine and increase the dose until buy viagra cvs an effective one is found. Others prefer to start with the highest dose and go to a lower dose only if a man complains of side effects.

In either case, it’s important for a man to communicate with his doctor to let him know how the dose he’s using is working.

For some men, daily administration of a low dose of one of the oral medicines may result in improved blood supply to the penis, resulting in better buy viagra cvs erections.

Switching from one of the oral medicines to another may be tried before proceeding to a more invasive or costlier treatment. However, there are few studies that viagra in medical store show any one of the drugs being significantly more effective than another.

Low testosterone Before a man concludes that oral drugs don’t work for him, he should have his testosterone levels checked to rule out hormone deficiency as the cause of (or as a contributor to) his sexual dysfunction. Other symptoms of low testosterone include a low sex drive and infertility.

Checking testosterone levels requires a blood test. If a man’s levels of testosterone are decreased or at the lower end of normal, his doctor may prescribe supplemental testosterone therapy, either as testosterone injections or testosterone gel, which is applied daily to the skin.
