According to Harvard Special Health Report Erectile Dysfunction, one study in the European Heart Journal looked at men newly diagnosed with heart disease, but without ED, who started treatment with the beta-blocker atenolol (Tenormin). Some of the study participants were told about the sexual side effect of the blood pressure drug, and ED was reported by almost one-third of the participants. In contrast, among those who were not told the drug's name or its side effects, only 3% said they experienced ED.

If the cause is believed to be organic but not hormonal, or if the patient defers psychological intervention, he can be offered the VCD or oral drug therapy. EDDM patients on organic nitrates or who have experienced or are concerned about potential adverse reaction to PDE-5 inhibitors are suitable candidates for the VCD. The VCD induces functional rigidity in 75% of patients with diabetes with autonomic neuropathy. Some patients or their partners may reject or discontinue the use of the VCD because it induces an unnatural erection, causes bruising and numbness of the penis, and or inhibits antegrade ejaculation.8
Erectile dysfunction (ED) is common, affecting almost 40% of men over 40 years of age (with varying degrees of severity) and increases in frequency with age.1 Erectile dysfunction and cardiovascular disease (CVD) share common risk factors including age, hypercholesterolaemia, hypertension, insulin resistance and diabetes, smoking, obesity, metabolic syndrome, sedentary lifestyle, and depression.2 Cardiovascular disease and ED also share a common pathophysiological basis of aetiology and progression.3 Numerous studies have established that ED (i) is frequent in men with established CVD, (ii) co-exists with occult coronary artery disease (CAD) and (iii) is an independent risk factor for future cardiovascular (CV) events both in men with established CVD and in men with no known CVD.2,4,5 In the latter group, ED precedes CAD, stroke, and peripheral arterial disease by a significant period that usually ranges from 2 to 5 years (average 3 years).2 Although the ED patient can be managed by various medical specialties, and preferably a collaborative approach is most effective, this review is oriented to the cardiologist. While this review deals exclusively with sexual health of men, female sexual health and its potential relation with CVD is also an interesting, yet underexplored, field. As in men, moderating common risk factors seems to improve female sexual health and may serve as an opportunity to decrease CVD risk, with the identification of sexual dysfunction being the starting point.6
The obvious risks are the same that accompany any surgery: infection, pain, bleeding, and scarring. If for some reason the prosthesis or parts become damaged or dislocated, surgical removal may be necessary. With a general success rate of about 90 percent, any of the devices will restore erections, but they will not affect sexual desire, ejaculation, or orgasm.

Treatments might be slightly different for different people, depending on their risk factors, but in general all treatment plans have similar elements: diet, exercise, and medications, if necessary (see the Table). Diet and exercise are the cornerstones of the treatment of atherosclerosis. Every diet should include low salt (especially for high blood pressure), low fat and cholesterol (especially for high cholesterol), and limited total calories (especially for patients who are overweight). People with diabetes mellitus should limit their intake of sugars and carbohydrates. Exercise helps to limit atherosclerosis. The more exercise, the better, but every little bit helps. The general recommendation is 30 minutes a day 5 days a week. Check with your doctor to be sure that an exercise program is safe for you. Cigarettes cause a variety of health problems, including atherosclerosis, so cigarette smoking should be stopped. If diet and exercise are not enough to control your atherosclerotic risk factors, then your doctor will prescribe medications. Heart attacks are prevented by controlling atherosclerotic risk factors, which means diet, exercise, and medications if necessary.
Erectile dysfunction is an accurate predictor of heart attacks and strokes in the future. Psychogenic components play a role in erectile dysfunction, but the most common and primary cause in most men is organic vascular insufficiency, meaning not enough blood gets to the penis. Erectile dysfunction usually occurs one to five years before a male manifests overt signs of cardiovascular disease. The first sign may be death.
The safety of PDE5 inhibitors in patients with IHD has been shown in multiple trials. Arruda-Olson et al. investigated the safety of sildenafil during exercise stress tests in patients with IHD to ascertain whether the drug induces or exacerbates myocardial ischaemia. This was a prospective, randomised crossover study that demonstrated safety of sildenafil when given 1 hour before an exercise stress test.69 Another study that investigated 120 trials of sildenafil revealed that the rates of MI and cardiovascular death with sildenafil are as low as with placebo.70
Furthermore, if feelings of sadness, bloating, or weight gain are prominent, it may be beneficial to measure a form of estrogen called estradiol. This form of estrogen can be elevated in men, particularly in those who are overweight, and may trigger these abnormal responses, increasing the risk of heart disease. Estradiol levels above 30 pg/mL are generally considered abnormal. Weight loss can help correct elevated estradiol, as can prescription “aromatase inhibitors,” such as Arimidex®. In addition, a nutritional supplement called chrysin has been shown in the laboratory to inhibit the aromatase enzyme that is responsible for converting testosterone to estradiol.24 You should consult your doctor to determine if this supplement may be helpful for you.
There’s one more thing to remember: A visit to a physician can be helpful even if a man doesn’t want to go near Viagra or try one of the alternatives. In some cases, a treatable medical condition such as low testosterone or depression could explain a case of ED. “Sexual health should not be viewed as a luxury, but rather as an essential component to wellness,” said urologist Ryan P. Terlecki, MD, of Wake Forest Baptist Health in North Carolina.
The American College of Cardiology is a 52,000-member medical society that is the professional home for the entire cardiovascular care team. The mission of the College is to transform cardiovascular care and to improve heart health. The ACC leads in the formation of health policy, standards and guidelines. The College operates national registries to measure and improve care, offers cardiovascular accreditation to hospitals and institutions, provides professional medical education, disseminates cardiovascular research and bestows credentials upon cardiovascular specialists who meet stringent qualifications.
The use of shock wave therapy has revolutionized the treatment of many aspects of medicine. High intensity extracorporeal shockwave therapy has been used for the treatment of nephro-urolithiasis while medium intensity shockwave therapy is used by orthopaedic surgeons to treat joint pain as well as tendinitis. Low intensity shockwaves therapy was first noted to improve ischaemia-induced myocardial dysfunction in animal studies when low intensity shockwaves were applied to porcine myocardium (13). Shockwaves induces a localized stress on cell membranes in the same way that shear stress affects endothelial cell membranes (14) and this triggers the release of angiogenic factors, such as increased NO production through increased activity of endothelial NO synthase (eNOS) and neuronal NO synthase (nNOS), platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) (15). These shockwaves also cause membrane hyperpolarization (16), activation of the Ras signaling pathway, non-enzymatic synthesis of NO and induction of stress fibers and intercellular gaps (17).
When these drugs don't work, there are other options. Medications that dilate blood vessels, such as alprostadil, can be injected or deposited in the penis; they work in more than 80 percent of men with diabetes. Beyond that, penile implants can be an effective surgical solution. Implants are either malleable rods, which can be manually adjusted to the desired position, or inflatable cylinders that fill with fluid when a pump under the skin of the scrotum is pressed.
Owing to its delicate nature, discussion about the sexual life of the patient is effective not on a circumstantial visit to the doctor, but on the basis of confidence between the patient and the physician, as is usually the case with the cardiologist. Thus, the cardiologist is given a unique opportunity to identify ED and thus ‘recharacterize’ the risk of the patient. In addition, since normal sexual activity is important to most men with CVD, irrespective of age, the cardiologist can clarify issues that relate to such activity after a cardiac event or to a specific cardiac condition (e.g. heart failure). Often, such issues are hampered by misconceptions from the side of the patient. Therefore, while less than half of the patients receive information about resuming sexual activity after a cardiac event, proper counselling increases their likelihood to resume their previous level of sexual activity by 50%.50 Furthermore, the cardiologist can increase adherence to the medication by clarifying that it is uncommonly the true cause of ED. Finally, proper counselling is required to ensure safety of concomitant PDE5 inhibitors medication, the use of which has the additional advantage to increase compliance to CVD mediation, especially in hypertension. It should be noted that while patients are often reluctant to bring up the issue of sexual health, they are relieved and respond positively when their cardiologist has done so. It should also be emphasized that, frequently, sexual counselling is more effective when done together with their partner.

Adequate cavernosal arterial inflow is necessary for penile erection. Arterial morphology,28 flow,29 and diameter30 differ between diabetic and nondiabetic populations with ED. BB and STZ-induced diabetic rats exhibit impairment of endothelium-mediated vascular smooth muscle relaxation, and proposed mechanisms include changes in the expression, activity, or post-translational modification of endothelial NOS.31

Unlike intraurethral suppositories, intracavernosal injection (IC) injection of vasoactive agents such as PGE-1 has consistently been shown to be effective in the treatment of ED in men with diabetes. In a study of 336 men with diabetes-related ED, 83% of patients reported erections satisfactory for intercourse after IC injection of PGE-1.55 Unfortunately, 24% of these patients also reported penile pain, one of the most common side effects of IC injection therapy. Other studies have noted similar effectiveness rates.56,57
“I’m hoping this study will drive that (tie) a little bit harder and faster so that physicians will routinely be including ED when they’re screening patients for cardiovascular disease,” he said. “Doctors should ask the question and consider whether hardening of the arteries is occurring, ask about family history and signs or symptoms like chest pain with exertion, and spend the requisite amount of time to find out what’s going on.”
Ginkgo is an herb that’s been used medicinally for thousands of years to treat a variety of ailments. This supplement may improve penile blood flow. Additionally, some reports suggest that ginkgo can increase bleeding risk. This makes it particularly dangerous for people using blood thinners. Other studies, including one from 2011, found no evidence of increased bleeding while using ginkgo.
There are a number of herbs and supplements for use in men with ED. However, the overall quality of the studies evaluating these treatments has been low. Therefore, evidence for the effectiveness and safety of these therapies is limited. Many of these therapies have known risks, and there’s a possibility that other risks are yet to be discovered. Always use CAM therapies with caution.
Another oral treatment that has been used with very little success is yohimbine (Yocon, Yohimex). This is an alpha 2 adrenergic receptor blocker that increases cholinergic and decreases adrenergic tone. It stimulates the mid-brain and increases libido. Optimal results occur when used in men with psychogenic ED. Side effects include anxiety and insomnia.
Diabetes care providers, while becoming more aware of the high prevalence of ED in men with diabetes, may not appreciate the importance of maintaining erectile function to their patients. A recent study by Rance et al.40 underscores the fact that diabetic men, regardless of whether they actually have ED, believe that ED has a major impact on quality of life and that it is as important to treat as many other conditions associated with diabetes. In an effort to determine the relative importance of treatment for ED compared to other diabetic complications, they gave 192 consecutive diabetic men and 51 control patients seen at two hospitals a standardized questionnaire that assessed the relative importance of a number of diabetic complications and the patients' willingness to pay per month to avoid a particular complication.
The impact of third-generation cardioselective beta-blockers such as carvedilol and nebivolol has also been investigated. Fogari et al. investigated the effect of carvedilol on erectile function in a double-blind crossover study involving 160 men newly diagnosed with hypertension and found chronic worsening of sexual function in those treated with carvedilol compared with valsartan and placebo.24
At the same time, people with diabetes are susceptible to a type of blood vessel damage known as endothelial dysfunction. A recent study found that men with ED are at a greater risk of heart disease, which is also associated with endothelial dysfunction. If blood vessels aren't in good working order, the penis may not get enough blood for an erection.
