When it comes to combating heart disease, most information sources promote drugs and surgery as the only viable options, with lip service to dietary advice that simply does not work. As a result, the demand for high-tech, expensive, but largely ineffective medical care is soaring, causing medical costs and insurance rates to skyrocket. This chase for "cures" is both financially devastating and futile. Morbidity and premature mortality from heart disease continue to rise, with no sign of abating.

Erectile dysfunction can be a symptom of heart disease. An erection is caused by engorgement of blood into the penile tissues which later becomes rigid for penetration. Men with heart problem suffer from an inadequate blood flow to the smooth tissues of the penis to achieve erection. A major cardiovascular disease known as Atherosclerosis is a result of fat accumulation in the arterial blood vessels. This build up of multiple plaques or fatty material causes the arteries to narrow and harden thus limiting blood flow. The arteries supplying your penis are smaller than those supplying your heart. In fact, ED can be an initial symptom of heart diseases like Atherosclerosis. Cardiovascular problems can also damage penile nerves and arteries, inhibiting erectile function. Experts found a consistent link between ED and heart disease. Other recent research conducted by health professionals has shown a direct connection between erection dysfunctions and heart problems.
Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject Impulse, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include papaverine, alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).
The Massachusetts Male Aging Study of 1,290 men, aged 40–70 years, has documented the extraordinarily high prevalence of erectile dysfunction among aging men: 50% of men at 50 years of age, and 70% by age 70 have erectile dysfunction.2 Furthermore, a recent Italian study of men with severe heart disease has uncovered an astounding 93% with erectile dysfunction 24 months before their heart attack or onset of heart disease symptoms.3

Counselling or sex therapy (58% of people find this works for them) –mind-related causes of erectile dysfunction can affect anyone. They are more likely if you experience erectile dysfunction at a younger age. Talking to a counsellor or therapist can help some people overcome erectile dysfunction related to these problems, possibly for good. They can also help you if your erectile dysfunction is causing you stress, as this can make matters worse.
The following products are considered to be alternative treatments or natural remedies for Erectile Dysfunction. Their efficacy may not have been scientifically tested to the same degree as the drugs listed in the table above. However there may be historical, cultural or anecdotal evidence linking their use to the treatment of Erectile Dysfunction.
Some research even suggests the effect of blood pressure drugs may be more psychological than physical. When ED occurs after a man begins to take a new medication, it's possible that anxiety about his health, rather than the medication, may trigger the problem. And being aware of possible side effects may make a man more likely to recognize them as abnormal.
Cardiovascular tolerance for sex is based on “functional reserve,” which corresponds to how closely the cardiovascular response to sex (in terms of heart rate, blood pressure level, and oxygen consumption) approaches the patient's peak response to exercise.85x85DeBusk, RF. Evaluating the cardiovascular tolerance for sex. Am J Cardiol. 2000; 86: 51F–56F
In the early years of my cardiology practice, I was surprised by the number of men with heart disease who also suffered from impotence. In fact, being incapable of having an erection was the norm rather than the exception after heart attack. In those days, impotence was widely attributed to the psychological depression that often followed heart attack.
These drugs are safe for healthy hearts, but all men with cardiovascular disease should take special precautions, and some cannot use them under any circumstances. The problem is their effect on arteries. All arteries, not just those in the penis, generate nitric oxide, so any artery can widen in response to Viagra, Levitra, or Cialis, causing blood pressure to drop temporarily by 5-8 mmHg, even in healthy men.
Yohimbine: The main component of an African tree bark, yohimbine is probably one of the most problematic of all natural remedies for ED. Some research suggests that yohimbine can improve a type of sexual dysfunction that is linked with a drug used to treat depression. However, studies have linked yohimbine to a number of side effects, which can include anxiety, increased blood pressure, and a fast, irregular heartbeat. Like all natural remedies, yohimbine should only be used after advice and under supervision from a doctor.
Overall, sildenafil appears to be relatively safe and effective for treatment of ED in men with stable cardiovascular disease who are not taking NO-donor medications. In a study of 105 men with ED and known or likely coronary artery disease, patients underwent symptom-limited supine bicycle echocardiography 2 times after receiving either sildenafil or placebo.63x63Arruda-Olson, AM, Mahoney, DW, Nehra, A, Leckel, M, and Pellikka, PA.

Conversely, and of significant clinical importance, is how often patients with ED as their first and sole clinical manifestation suffer from subclinical CAD.17 Previous studies reported a rate of inducible ischaemia by exercise stress testing (EST) in 22% (with a wide range of 5–56%) of ED patients reflecting differences in patient population, risk factors and criteria used for ED and CAD diagnosis. Interestingly, those patients further assessed with coronary angiography had obstructive atherosclerosis in >90% of cases.4,18 In a prospective angiographic study, we documented that 19% of ED patients suffer from clinically silent obstructive CAD.18

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
Other effective Diabetic Erectile Dysfunction Treatment therapies available include (a) an intraurethral suppository of the vasodilator drug alprostadil (prostaglandin E1), (b) intracavernosal self injection (penile self injection) of the non-specific PDE drug papaverine, the non-selective alpha-adrenergic antagonist phentolamine, and the vasodilator prostaglandin E1, used alone or in combination, or (c) penile prostheses (penile implants).

Some commonly prescribed cardiovascular drugs (beta-blockers, diuretics, angiotensin-converting enzyme inhibitors, etc.) contribute to ED.18 Previous studies have shown a strong association between ED and diuretics in patients treated with hydrochlorothiazide or chlorthalidone.19,20 It has also been shown that patients treated with first-generation non-selective beta-blockers, such as propranolol, had more frequent ED than those treated with a placebo.21

PubMed | Google ScholarSee all References The risk of ED was 1.83 times higher in men with a total cholesterol level greater than 240 mg/dL as opposed to less than 180 mg/dL. Also, an HDL cholesterol level greater than 60 mg/dL was found to be protective against the development of ED. In the MMAS, HDL cholesterol levels were noted to have an inverse relationship with the presence of ED.4x4Feldman, HA, Goldstein, I, Hatzichristou, DG, Krane, RJ, and McKinlay, JB.

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

Erections also require neural input to redirect blood flow into the corpora cavernosae. Psychogenic erections secondary to sexual images or auditory stimuli relay sensual input to the spinal cord at T-11 to L-2. Neural impulses flow to the pelvic vascular bed, redirecting blood flow into the corpora cavernosae. Reflex erections secondary to tactile stimulus to the penis or genital area activate a reflex arc with sacral roots at S2 to S4. Nocturnal erections occur during rapid-eye-movement (REM) sleep and occur 3–4 times nightly. Depressed men rarely experience REM sleep and therefore do not have nocturnal or early-morning erections.
The treatment of ED using TCM ties in with the treatment of late-onset hypogonadism (LOH). LOH occurs due to the breakdown in coordination between the heart and the kidneys, deficiencies of the spleen and kidney (yang), deficiencies of the liver and kidney (yin) and deficiencies of the kidney (yin and yang). The endocrine function of the pituitary and gonads becomes disordered with age due to a depression of overall function. This results in accumulation of free radicals and other toxins that cannot be relieved solely with male hormone supplementation. Warm yang can energize kidneys to benefit the body, remove toxins, invigorate qi and promote blood circulation. Free radicals are removed, blood fat regulated, cardio-cerebral blood flow improved and again the key here is to improve the function of the digestive, respiratory and endocrine systems, hence regulating the body in every aspect holistically (28).
Vasculogenic sexual dysfunction is the main cause of sexual dysfunction in untreated hypertensive patients. However, due to the complex etiologic and pathophysiologic nature of sexual dysfunction, exclusion of concomitant diseases and drugs should be the initial step when approaching a hypertensive patient with this clinical condition that is not receiving any antihypertensive medication. Consequently, a significant amount of neurological, psychiatric, urologic and endocrine disorders should be ruled out before vasculogenic sexual dysfunction is diagnosed.

Chronic heart failure often develops after other cardiac problems have damaged or weakened the heart, leaving it too weak or too stiff to fill and pump efficiently. Many underlying heart conditions can lead to heart failure. It can develop quickly after damage caused by a heart attack, or it can develop gradually after years of high blood pressure or coronary artery disease.
In a 2005 study, three months of twice-daily sets of kegel exercises combined with biofeedback and advice on lifestyle changes, such as quitting smoking, losing weight, and limiting alcohol, worked far better than just giving the participants advice. “Wearing tight pants will affect impotence along with some other medical conditions like diabetes and heart disease,” which can also affect a man’s degree of impotence, Dr. Jennifer Burns, specializing in family practice with an emphasis on gastrointestinal health at the BienEtre Center, told Medical Daily.

The blood supply to your penis starts in your heart and flows through arteries in the belly to even smaller arteries that branch off to carry blood into the penis. With sexual stimulation, these blood vessels need to rapidly increase blood flow. If these blood vessels are blocked (atherosclerosis) by coronary artery disease, you may not be able to achieve or maintain an erection.11


Cardiovascular disease and ED represent 2 common disease processes that are often intimately associated with one another. These common pathophysiological links necessitate a solid scientific and clinical understanding of these 2 disorders and a team effort between the cardiologist and urologist to provide effective management strategies for these patients.

Impotence, or erectile dysfunction (ED), is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse.  To understand the underlying causes of impotence, it helps to know the basics about how an erection develops, along with potential problems that get in the way. Erections begin in the brain with a thought related to sexual desire. Then a chemical message travels from the brain to the penis. Blood flow to the penis increases as blood vessels leading to the reproductive system relax and allow for increased circulation.
Some research even suggests the effect of blood pressure drugs may be more psychological than physical. When ED occurs after a man begins to take a new medication, it's possible that anxiety about his health, rather than the medication, may trigger the problem. And being aware of possible side effects may make a man more likely to recognize them as abnormal.

Men with diabetes tend to develop erectile dysfunction 10 to 15 years earlier than men without diabetes. As men with diabetes age, erectile dysfunction becomes even more common. Above the age of 50, the likelihood of having difficulty with an erection occurs in approximately 50% to 60% of men with diabetes. Above age 70, there is about a 95% likelihood of having some difficulty with erectile dysfunction.
