Abstract
Cardiovascular disease (CVD) is the highest cause of death globally with more
people dying annually from it than from any other cause. CVD is associated with
modifiable risk factors (dyslipidaemia, hypertension and diabetes) and treating
each of these factors lowers the risk of CVD. It is impossible to estimate the
benefit of risk factor modification in the individual patient and extrapolating
data from multiple trials is difficult. It would be useful to have a marker of
risk that accurately estimates real time risk by measuring blood flow factors
associated with the pathogenesis of atheroma. The aim of this preliminary study
was to validate a low-cost measurement technique for obtaining blood flow
velocity profiles and assess whether any of the measured and calculated factors,
based on computational fluid dynamics (CFD) simulation, known to be associated
with atheroma was associated with coronary heart disease (CHD), thus
establishing its feasibility and acceptability as a clinical tool and suggesting
areas for future research. Our study identified (i) that mean peak systolic (PS)
velocity being associated with CHD; individuals without CHD: mean (SD) = 62.8
(16.1) cm/s, with CHD: mean (SD) = 53.6 (17.3) cm/s,
p = 0.042; and (ii) that low-cost, portable ultrasound, which
is routinely available in general practice, is a suitable assessment tool.

Abstract
Introduction: Erectile dysfunction (ED) affects more than 150 million men worldwide, with deleterious effects on quality of life. ED is known to be associated with ischemic heart disease but the impact of ED in patients with peripheral arterial disease (PAD) is unknown. We assessed the prevalence and severity of ED in patients with PVD. Methods: Following ethical approval, sequential male patients diagnosed with PAD over a 1-year period following diagnosis of intermittent claudication. The patient demographics and comorbidities were recorded, with the International Index of Erectile Function (IIEF-5) questionnaire used to grade severity of ED. Computed tomographic angiography and severity of stenosis in the proximal vessels and internal pudendal arteries were correlated using a modified Bollinger Matrix scoring system. Results: 60 patients were recruited, most (77.2%) reported erectile dysfunction (52.5% severe, 22.5% moderate). Patients with severe ED were more likely to have 2 or more comorbidities (P = .009). 86.7% with severe ED had bilateral internal pudendal artery stenosis with a mean modified Bollinger score of 17.6. 35.5% of moderate ED patients had bilateral internal pudendal stenosis with a mean Bollinger score of 11.75. There was significant difference in overall scores between moderate and severe erectile dysfunction (p< 0.05), thus indicating a potential link between ED severity and extent of vessel stenosis. Conclusion: There is a substantial burden of clinically significant ED among patients with PAD. This study suggests ED should be discussed with all PAD patients and ED may precede a PAD diagnosis. There is scope for endovascular revascularization as a treatment option for ED secondary to arterial insufficiency.

J Sex Med 2020; 17:1086-1093. [PMID: 32192923 DOI: 10.1016/j.jsxm.2020.02.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Revised: 02/07/2020] [Accepted: 02/10/2020] [Indexed: 01/09/2023]
Abstract
BACKGROUND The angiographically documented association between severity of coronary artery disease (CAD) and aorto-ilio-pudendal (A-I-P) artery disease and vascular erectile dysfunction (ED) was not yet settled. AIM To assess the relation between angiographically proved CAD and A-I-P artery disease in patients with ischemic heart disease (IHD)-associated vascular ED. METHODS 60 men were assigned to 3 study groups: Group 1 (n = 25), patients who had IHD and ED; group 2 (n = 25), patients who had IHD and had no ED; group 3 (n = 10), patients who had ED and had no suspected IHD. All patients were subjected to detailed medical, cardiac, and sexual history. International Index of Erectile Function and penile color Doppler ultrasound were used to assess ED. Quantitative coronary angiography and invasive angiography were used to assess the vascular tree for the right and left (A-I-P) arteries. Endothelial markers, that is, endothelial microparticles and endothelial progenitor cells were also assessed. OUTCOMES The main outcome measures are assessment of ED and angiographically proved CAD and A-I-P artery disease. RESULTS The mean age ± SD of the 3 study groups were 50.4 ± 6.6, 51.4 ± 3.9, and 49.9 ± 6.1 years, respectively, with no statistically significant difference among groups (P = .380). There were significant higher rates of left main (LM) lesions (≥50%), CAD (≥70%), right and left internal pudendal artery lesions, and right and left internal iliac artery lesions in G1 in comparison with G2 and G3. Patients with ED alone had a higher rate of peripheral lesions compared with patients with CAD alone. 10 percent of patients with ED alone had CAD. Patients in G1 had notably higher rates of peripheral lesions than the other groups combined Patients with left internal pudendal artery lesions had a chance by 1.25 and 2.11 times to have LM lesions and significant CAD, respectively. There was a significant increase of endothelial microparticles in G1 in comparison with other groups (P < .05). CLINICAL IMPLICATIONS The clinical implications are uses of peripheral angiograghy as a diagnostic tool in patients with CAD-associated vascular ED may have a clinical merit. STRENGTHS & LIMITATIONS The strengths in the present study are the use of angiography, color Doppler ultrasound, and standardized instruments. The main limitations are the small sample size and lack of intervention and longitudinal data. CONCLUSION ED correlates more with A-I-P vascular lesions compared with CAD alone. There was a statistically significant association between severity of CAD including LM significant lesions and A-I-P arteries disease in patients with CAD-associated vascular ED.

Abstract
OBJECTIVE. Erectile dysfunction (ED) is a common medical condition that has a high prevalence and incidence worldwide and may have a significant impact on both physical and psychosocial health. The purpose of this article is to review the role of penile Doppler sonography in the assessment of ED. CONCLUSION. Penile Doppler sonography is an essential tool for differentiating between vascular and nonvascular causes of ED; therefore, radiologists must be familiar with the imaging protocol, the limitations of the technique, and interpretation of its findings, to warrant an accurate diagnosis and appropriate patient management.

Abstract
BACKGROUND The association between subclinical cardiovascular disease and subsequent development of erectile dysfunction (ED) remains poorly described. HYPOTHESIS Among multiple subclinical atherosclerosis and vascular dysfunction measurements, coronary artery calcium (CAC) score best predicts ED. METHODS After excluding participants taking ED medications at baseline, we studied 1862 men age 45 to 84 years free of known cardiovascular disease from the Multi-Ethnic Study of Atherosclerosis (MESA) with comprehensive baseline subclinical vascular disease phenotyping and ED status assessed at MESA visit 5 (9.4 ± 0.5 years after baseline) using a standardized question on ED symptoms. Multivariable logistic regression was used to assess the associations between baseline measures of vascular disease (atherosclerosis domain: CAC, carotid intima-media thickness, carotid plaque, ankle-brachial index; vascular stiffness/function domain: aortic stiffness, carotid stiffness, brachial flow-mediated dilation) and ED symptoms at follow-up. RESULTS Mean baseline age was 59.5 ± 9 years, and 839 participants (45%) reported ED symptoms at follow-up. Compared with symptom-free individuals, participants with ED had higher baseline prevalence of CAC score >100 (36.4% vs 17.2%), carotid intima-media thickness Z score >75th percentile (35.3% vs 16.6%), carotid plaque score ≥2 (39% vs 21.1%), carotid distensibility <25th percentile (34.6% vs 17.1%), aortic distensibility <25th percentile (34.2% vs 18.7%), and brachial flow-mediated dilation <25th percentile (28.4% vs 21.3%); all P < 0.01. Only CAC >100 (odds ratio: 1.43, 95% confidence interval: 1.09-1.88) and carotid plaque score ≥2 (odds ratio: 1.33, 95% confidence interval: 1.02-1.73) were significantly associated with ED. CONCLUSIONS Subclinical vascular disease is common in men who later self-report ED. Early detection of subclinical atherosclerosis, particularly advanced CAC and carotid plaque, may provide opportunities for predicting the onset of subsequent vascular ED.

Abstract
Objective To review local published data on the diagnosis and treatment of erectile dysfunction (ED) in Arab countries. Methods MEDLINE was searched for English-language articles published from 2000 to 2011, using the search terms ‘Arab countries’, ‘sexual dysfunction’, ‘diagnosis’ and ‘treatment’. Results In all, 86 articles were found to be relevant to this review; only a few had a high level of evidence and the remaining studies used an uncontrolled design. Several local studies were consistent with previous reports showing that a customised diagnostic pathway, with full consideration of the patient’s goals, is adopted by most clinicians to treat ED. For an effective treatment, the evaluation methods should answer important questions about the aetiology and severity of ED, as well as the patient’s and partner’s goals and expectations. As ED is known to be associated with many common medical comorbidities and medications, careful questioning can yield information about peripheral vascular disease, coronary artery disease, diabetes, hypertension, dyslipidaemia, and tobacco and alcohol use. The presence of psychological, neurological or chronic debilitating diseases can direct further evaluation. Conclusion The methods used for the diagnosis and treatment of ED need more investigation, especially in Arab countries. Only a few studies addressed the results of different methods of investigating and treating ED among Arab men.

Abstract
OBJECTIVE To review the contemporary knowledge of local investigations in the Arab countries that were conducted to identify the magnitude of erectile dysfunction (ED) and its correlates among men in this region. METHODS MEDLINE was reviewed for English-language reports from 2000 to 2011 for Arab countries, using the terms 'erectile dysfunction' and 'prevalence'. RESULTS In all, 102 articles were found to be relevant to the review. Unfortunately only a few had a high level of evidence and the remaining studies were not controlled in their design. Several local studies showed that the prevalence of ED was >40% among Arab men. Risk factors and medical comorbidities that negatively affect the cardiovascular system, endothelial function and ultimately erectile function were common in men in Arab countries. For instance, at least five Arab countries are included in the top 10 countries worldwide with a high prevalence of diabetes mellitus. The global statistics showed that other risk factors such as obesity, smoking, hypertension and dyslipidaemia are also very prevalent in Arab countries. This fact can explain the high incidence of both cardiovascular disease and ED among Arab men. CONCLUSION ED is very prevalent among Arab men. Arab countries are among those with the highest prevalence of endothelial dysfunction risk factors, which could explain this high prevalence of ED.

Abstract
Résumé
La dysfonction érectile (DE) est une pathologie multifactorielle fréquente, dont l’origine organique ou mixte est considérée actuellement comme dominante chez l’homme après 50 ans. La plupart des DE vasculotissulaires sont liées à une dysfonction endothéliale, en relation avec les principaux facteurs de risque cardiovasculaires (FRCV). La DE représente un indicateur de la santé vasculaire en général. Elle est aussi prédictive d’événements cardiovasculaires (ECV), notamment de coronaropathies. Elle a également été associée aux artériopathies des membres inférieurs et aux accidents vasculaires cérébraux. Le pharmaco-écho-doppler pénien (PEDP) est un examen assez peu utilisé aujourd’hui dans la prise en charge d’une DE, la recherche étiologique n’étant encore le plus souvent pas considérée comme nécessaire à la prise en charge thérapeutique, mais également en raison de l’absence de standardisation. Cependant, de nombreuses publications ont mis récemment en évidence que l’origine vasculotissulaire d’une DE, établie sur des critères vélocimétriques enregistrés après injection intracaverneuse (IIC) de substances vasoactives, renforçait la valeur prédictive de la DE concernant les événements et la mortalité cardiovasculaires (CV), justifiant un intérêt accru pour réaliser cet examen.

Abstract
The landmark Massachusetts Male Ageing Study shed new light on the prevalence of erectile dysfunction (ED) and drew attention to ED as a disease of ageing. Over the years, ED has been linked to the development of cardiovascular disease (CVD) in some patients. There is clear evidence that ED and CVD share and have a similar risk factor profile. CVD is one of the most recognizable causes of mortality and early detection coupled with prevention of mortality from CVD has been the prime interest of many researchers. Consequently, there has been a multidisciplinary curiosity regarding the proposal to use ED as a marker for future CVD. In fact, there have been several proposals to use ED as a screening tool for future CVD. We performed a comprehensive search of two main databases-PubMed and Cochrane Library using a combination of keywords such as acute myocardial infarction, coronary artery disease (CAD) and ED. Journal articles from January 2000 to June 2011 were reviewed. We included all articles discussing the relationship between ED and CVD in the English language. All the relevant randomized controlled trials, cohort and retrospective studies, and review articles were included in our overall analysis in an attempt to answer the question whether all patients with ED should be clinically evaluated for CVD. The results showed a link between ED and the development of future CVD in some patients, but ED was not shown to be an independent risk predictor that is any better than the traditional Framingham risk factors. Screening for CVD may, however, be rewarding in younger patients with severe ED and in patients with concurrent CVD risk factors.

Abstract
INTRODUCTION Erectile dysfunction (ED) depression and ischemic heart disease (IHD) had long been classified as independent medical conditions managed by unrelated medical services. Recent studies have revealed the intimate associations among the three conditions. However, when a patient presents with one component of this triad, whether the physicians should also screen for the other two components is still an important question to be answered. AIM The purpose of this Continuing Medical Education article is to review contemporary knowledge regarding the reinforcing associations between the three conditions and to highlight the importance of screening for the other two components when a patient presents with one component of this triad, thus enabling best-practice management. METHODS An English-language MEDLINE review was performed from 1990 to present-day for the association between ED, depression and IHD. MAIN OUTCOME MEASURE Current state of information regarding associations among the three conditions. RESULTS Recent studies have established a new paradigm for the intimate associations among the three conditions. Furthermore, various risk factors and medical co-morbidities such as age, obesity, sedentary lifestyle, smoking, heart disease, hypertension, dyslipidemia, diabetes, and related medications have been demonstrated to be highly associated with psychological disorders, cardiovascular diseases, and sexual dysfunctions. CONCLUSIONS The integrative view and holistic approach with full consideration of the property of each condition is the appropriate way for the diagnosis and management of patients with these conditions.

Abstract
The metabolic syndrome is common in countries with Western lifestyles. It comprises a number of disorders-including insulin resistance, hypertension and obesity-that all act as risk factors for cardiovascular diseases. Urological diseases have also been linked to the metabolic syndrome. Most established aspects of the metabolic syndrome are linked to benign prostatic hyperplasia (BPH) and prostate cancer. Fasting plasma insulin, in particular, has been linked to BPH and incident, aggressive and lethal prostate cancer. The metabolic syndrome has also been shown to be associated with nonprostatic urological conditions such as male hypogonadism, nephrolithiasis, overactive bladder and erectile dysfunction, although data on these conditions are still sparse. Overall, the results of studies on urological aspects of the metabolic syndrome seem to indicate that BPH and prostate cancer could be regarded as two new aspects of the metabolic syndrome, and that an increased insulin level is a common underlying aberration that promotes both BPH and clinical prostate cancer. Urologists need to be aware of the effect that the metabolic syndrome has on urological disorders and should transfer this knowledge to their patients.

Abstract
* A significant proportion of men with erectile dysfunction (ED) exhibit early signs of coronary artery disease (CAD), and this group may develop more severe CAD than men without ED (Level 1, Grade A). * The time interval among the onset of ED symptoms and the occurrence of CAD symptoms and cardiovascular events is estimated at 2-3 years and 3-5 years respectively; this interval allows for risk factor reduction (Level 2, Grade B). * ED is associated with increased all-cause mortality primarily due to increased cardiovascular mortality (Level 1, Grade A). * All men with ED should undergo a thorough medical assessment, including testosterone, fasting lipids, fasting glucose and blood pressure measurement. Following assessment, patients should be stratified according to the risk of future cardiovascular events. Those at high risk of cardiovascular disease should be evaluated by stress testing with selective use of computed tomography (CT) or coronary angiography (Level 1, Grade A). * Improvement in cardiovascular risk factors such as weight loss and increased physical activity has been reported to improve erectile function (Level 1, Grade A). * In men with ED, hypertension, diabetes and hyperlipidaemia should be treated aggressively, bearing in mind the potential side effects (Level 1, Grade A). * Management of ED is secondary to stabilising cardiovascular function, and controlling cardiovascular symptoms and exercise tolerance should be established prior to initiation of ED therapy (Level 1, Grade A). * Clinical evidence supports the use of phosphodiesterase 5 (PDE5) inhibitors as first-line therapy in men with CAD and comorbid ED and those with diabetes and ED (Level 1, Grade A). * Total testosterone and selectively free testosterone levels should be measured in all men with ED in accordance with contemporary guidelines and particularly in those who fail to respond to PDE5 inhibitors or have a chronic illness associated with low testosterone (Level 1, Grade A). * Testosterone replacement therapy may lead to symptomatic improvement (improved wellbeing) and enhance the effectiveness of PDE5 inhibitors (Level 1, Grade A). * Review of cardiovascular status and response to ED therapy should be performed at regular intervals (Level 1, Grade A).

Abstract
INTRODUCTION In the era of orally active agents, dynamic penile color-duplex ultrasound (D-PCDU) is not considered a necessary first screening for all patients with erectile dysfunction (ED). Various parameters, such as peak systolic flow velocity, end diastolic velocity, resistance index, acceleration time, and degree of arterial dilatation, have been suggested for the diagnosis of vascular ED by D-PCDU. AIM To highlight the clinical utility and evidence-based interpretation of D-PCDU criteria. METHODS Extensive, unsystematic PubMed literature search reviewing relevant data on D-PCDU in the evaluation of male ED. RESULTS The advantage of ultrasound is the minimally invasive nature of the procedure and the ability to screen patients to identify a normal arterial response of cavernous arteries. Men with sexual dysfunctions above 55 years of age and comorbidities are more likely to have multi-organ vascular dysfunction and may necessitate further testing because erectile failure may be the first presenting symptom requiring investigation and treatment even in the absence of cardiovascular risk factors. All patients affected with Peyronie's disease and younger men with persistent ED, a history of pelvic traumas, or fractures of the penile shaft should be offered ultrasonographic penile blood flow studies before referral to surgery or more invasive vascular investigations. CONCLUSIONS In the near future, D-PCDU may be used in preference to patients presenting with or without vascular risk factors, particularly those not responding to first-line orally active drugs and seeking an explanation as to why these agents failed.

Abstract
INTRODUCTION Enhanced external counterpulsation (EECP) is a noninvasive outpatient treatment used for patients with intractable angina refractory to aggressive surgical and medical treatment. Recent results have demonstrated a positive impact of EECP on patients with ischemic heart disease (IHD)-associated erectile dysfunction (ED). AIM To assess the effect of IHD duration and number of EECP courses on efficacy and satisfaction rate of EECP on patients with IHD-associated ED. MAIN OUTCOME MEASURES We compared pre- and post-EECP responses to erectile function (EF) domain, Q3 and Q4 of the International Index of Erectile Function score in patients who received one or two courses of EECP and those who had <5- or >or=5-years duration of IHD. METHODS As mentioned in part I a total of 44 male patients with intractable angina caused by coronary insufficiency were enrolled in this study. Treatment course of EECP consists of 35 1-hour sessions over 7 weeks. Another 35 1-hour sessions over another 7 weeks were offered to patients who received one course and required a second course because of no or minimal improvement from class IV to class III angina after the first course. RESULTS Patients who received only one course (N = 34) had significantly higher EF domain, Q3 and Q4, in pre- and post-EECP results than patients who received two courses (N = 10) after they completed the first course. Patients who had <5-years duration of IHD had significantly higher pre- and post EECP than patients who had >or=5 years regarding EF domain, Q3 and Q4. Considering the global efficacy question, overall satisfaction, and angina, there were significant improvements of post EECP in patients with <5 years than in patients with >or=5-years duration of IHD. CONCLUSION The efficacy and satisfaction rate of EECP in patients with IHD-associated ED were negatively influenced by longer duration of IHD and requirement of a second course of EECP.

Abstract
INTRODUCTION Recently it has been demonstrated that enhanced external counterpulsation (EECP) could improve erectile dysfunction (ED) in patients with refractory ischemic heart disease (IHD). AIM To assess the effect of risk factors on the efficacy and the satisfaction rate of EECP in patients with coronary artery disease (CAD)-associated ED. MAIN OUTCOME MEASURES To assess the effect of risk factors on EECP efficacy and satisfaction rate, we compared the pre- and post-EECP responses to erectile function domain, Q3, and Q4 in patients with and without risk factors. Overall satisfaction and global efficacy question (GEQ) were also assessed. METHODS A total of 44 male consecutive patients with intractable angina caused by coronary insufficiency which cannot be controlled by conventional therapy were enrolled in this study. Patients were screened and followed up for ED using erectile function domain of the International Index for Erectile Function. A thorough sexual, medical, and psychosocial history was taken from all patients. RESULTS All patients had severe diffuse triple vessels disease. They all had class III or IV angina. They were receiving the maximal antianginal pharmacotherapy. The mean age +/- SD was 57.1 +/- 5.6 years. Of the patients, 63.9% were below 60 years, and 86.4% were current or ex-smokers. There were significant differences between pre- and post-EECP regarding erectile function domain, Q3, and Q4. The sociodemographic variables were not significantly different among the studies groups and had not affected the GEQ or overall satisfaction. Overall satisfaction and GEQ were negatively influenced by smoking and presence of more than two risk factors. However, diabetes, hypertension, dyslipidemia, myocardial infraction, and obesity have not had such effects. CONCLUSIONS The efficacy and satisfaction rate of EECP in patients with CAD-associated ED were negatively influenced by presence of risk factors; however, the global efficacy and the overall patients' satisfaction were encouraging.

Abstract
INTRODUCTION Evidence is accumulating in favour of a link between erectile dysfunction (ED) and coronary artery disease (CAD). This review attempts to identify which patients, among those with ED and no cardiovascular (CV) disease, should be screened for early, subclinical CAD, which coronary targets should be investigated, and which tests should be used. MATERIALS AND METHODS A comprehensive evaluation of available published data included analysis of published full-length papers that were identified with Medline and Cancerlit from January 1988 to January 2006. RESULTS Initial screening of patients with ED may adopt risk assessment office-based approaches to score patients into low, intermediate, or high risk of future cardiovascular events. Attention should be drawn to patients at intermediate risk. Targets for the assessment of subclinical CAD in this subset of patients should include both obstructive (flow-limiting) and nonobstructive (non-flow-limiting) CAD. Some tests address obstructive atherosclerosis by directly assessing coronary flow reserve (i.e., standard exercise stress test, rest/stress myocardial scintigraphy or echocardiography). Other tests are general measures of atherosclerosis burden (not necessarily obstructive) either in the coronary circulation (i.e., coronary calcium score by electron-beam computed tomography), or in extracoronary vessels (i.e., ankle brachial index, carotid intima-media thickness by B-mode ultrasound) as surrogate markers of CAD. Although a systematic use of these measures of nonobstructive atherosclerosis burden has not yet been recommended in the guidelines for coronary risk assessment, their use is progressively being extended from the research area to clinical practice. CONCLUSIONS ED is definitely a vascular disorder and all men with ED should be considered at risk of CV disease until proven otherwise. Available risk assessment charts should be used to stratify (low, intermediate, and high) the coronary risk score in each patient with ED.

Abstract
Erectile dysfunction (ED) is the consistent inability to achieve and maintain an erection sufficient for satisfactory sexual activity. Erectile dysfunction affects as many as 30 million men in America, with an increasing prevalence with age. Erectile dysfunction is secondary to organic, psychogenic and combined causes. The first part of this review article describes the guidelines for evaluation and treatment plans for men with ED. It also describes the normal sonographic anatomy of the penis, sonographic technique for evaluation of ED and the normal phases of erection.

Abstract
A number of disease processes of the penis including Peyronie's disease, priapism, penile fractures and tumors are clearly visualized with ultrasound. Diagnostic evaluation of erectile dysfunction (ED) by penile dynamic colour-duplex Doppler ultrasonography (D-CDDU) is actually considered a second level approach to ED patients because of the fact that intracavernous injections test IV with prostaglandin-E(1) may provide important information about the patients' erectile capacity. However, no direct vascular imaging and a high percentage of false negative diagnoses of vasculogenic ED are its major pitfalls and subsequent treatment decisions remain quite limited. The occurrence of ED and its sentinel relationship to cardiovascular disease has prompted more accurate vascular screening in all patients even in the absence of cardiovascular risk factors. The sonographic evaluation of the intima-media thickness of the carotid arteries may sometimes represent an early manifestation of diffuse atherosclerotic disease and endothelial damage. This latter finding is often the cause of failure to oral agents, i.e. phosphodiesterase inhibitors, because of inability of the dysfunctional endothelium to release nitric oxide. D-CDDU represents an accurate tool to investigate cavernous artery inflow and venous leakage when compared with more invasive diagnostic techniques i.e. selective arteriography and dynamic infusion cavernosometry along with cavernosography.

Abstract
We evaluated the prevalence and risk factors for erectile dysfunction (ED) and interest in ED treatment among Japanese men being treated for type 2 diabetes mellitus. Patients (40-79 years; n=1118) completed the 5-item version of the International Index of Erectile Function (IIEF-5), and questions related to interest in ED pharmacotherapy, subjective symptoms of diabetes, and general quality of life. A separate survey completed by physicians examined the relationships between age, diabetic treatments (insulin or oral), symptoms of diabetes (poor glycemic control, microangiopathy), complications of diabetes (hypertension, ischemic heart disease, cerebrovascular disease), and ED. The prevalence of ED in patients with diabetes was 90%, a rate double that of non-diabetic individuals. Multivariate analyses revealed that age, insulin therapy, microangiopathy, hypertension, history of cerebrovascular or cardiovascular disease, leg dysesthesia, dysuria, insomnia, and anorexia all represented significant risk factors for ED. Half of all respondents were interested (29%) or would consider pharmacotherapy for ED (21%). These findings suggest that ED is a significant problem in Japanese men with diabetes, and that specific risk factors increase the prevalence of ED. Furthermore, the survey results expose national attitudes toward treatment of ED.

Abstract
OBJECTIVES Erectile dysfunction (ED) shares common risk factors with coronary artery disease (CAD). It has been suggested that ED may be considered a clinical manifestation of a generalized vascular disease affecting also the penile arteries. The aim of this prospective study was to evaluate angiographically the incidence of asymptomatic CAD in men with ED of vascular origin. METHODS Fifty consecutive asymptomatic men, aged 41-74 years, with non-psychogenic and non-hormonal ED were comprehensively evaluated using medical history and examination, exercise treadmill test and stress echocardiography. Patients who had positive one or both of the two non-invasive procedures were referred for coronary arteriography in order to document CAD and evaluate the severity of the disease. RESULTS The mean time interval between the onset of ED and cardiological assessment was 25 months (range 1-66). Smoking (32 patients/64%), hypertension (31 patients/62%) and hyperlipidemia (26 patients/52%) were the most common risk factors. Moreover, 35 men (70%) had two or more risk factors. Twelve patients (24%) with ED had positive one or both of the two non-invasive procedures and one patient presented with acute myocardial infarction before he completed the non-invasive investigation. Coronary arteriography performed in ten patients (in nine with positive one or both of the two non-invasive procedures [while the other three refused], and in the patient with acute myocardial infarction) demonstrated that one patient had three-vessel disease, two patients had two-vessel disease and six patients had single-vessel disease. CONCLUSIONS A considerable proportion (9/47 or 19%) of patients with ED of vascular origin has angiographically documented silent CAD. These findings support the strategy that patients with ED should undergo further cardiovascular evaluation.

Abstract
OBJECTIVE To assess if there is an underlying vascular association between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). MATERIALS AND METHODS A total of 374 male patients with ED were enrolled in this study. Patients were interviewed for ED using the International Index of Erectile Function. Assessments for penile vasculature using color Doppler ultrasonography and rigidometer were performed. All patients were also screened for LUTS using the International Prostate Symptoms Score. All patients underwent routine laboratory investigation, plus total testosterone and prolactin assessment. RESULTS Mean age+/-SD was 54.4+/-8.9 years with an age range of 28-84 years. Eighty-five percent of the patients had organic causes of ED. Of the patients, 80.7% had different degrees of LUTS. There was a significant association between presence of LUTS and: arteriogenic and neurogenic causes of ED, poor response to intracorporeal injection, poor rigidity in the rigidometer, and low peak systolic velocity of the cavernosal arteries (p < 0.05 for each). No significant association was found between presence of LUTS and increasing values of end diastolic velocity or decreasing values of resistive index of the cavernosal arteries (p > 0.05 for each). There was a significant association between the higher degrees of LUTS and the decreasing values of peak systolic velocity (p < 0.05). CONCLUSIONS This study demonstrated that reduced peak systolic velocity of the cavernous artery does associate with LUTS in patients with erectile dysfunction. Further studies are warranted to address the underlying vascular mechanisms of ED in patients with LUTS.

Abstract
OBJECTIVE To evaluate the possible improvement of sexual activity following a non on-demand administration of a long half-life selective inhibitor of phosphodiesterase type 5 (PDE-5) in elderly patients without major cardiovascular risk factors. METHODS Sixty subjects with erectile dysfunction (ED) aged 60-70 years and 30 control patients aged 18-40 years, affected by psychogenic ED, were studied. All underwent routine and hormonal blood tests, Nocturnal Penile Tumescence Rigidity Monitoring test (NPTRM), ultrasonographyc evaluation of common carotid artery intima-media thickness (IMT) and penile colour Doppler ultrasonography (P-CDU). All patients underwent therapy with tadalafil 20 mg in alternative days, non on-demand, at 5.00 p.m., for three consecutive months. IIEF-5, NPTRM test and P-CDU were re-evaluated one month after the end of the therapy. RESULTS Among elderly subjects 20 (33%) had normal carotid IMT (< 0.9 mm), 15 (25%) minimal increase of carotid thickness (IMT = 0.9-1.2 mm) and 25 (42%) one or more carotid plaques (IMT > 1.3 mm). NPTRM and P-CDU parameters were inversely related to different degrees of carotid wall alteration and showed a significant improvement respect to pre-treatment only in patients without atherosclerotic plaques. Also IIEF-5 showed significant improvements only in patients without atherosclerotic plaques. CONCLUSIONS In elderly subjects with slight or no signs of vascular disease at the carotid level, chronic and non on-demand treatment with tadalafil can induce spontaneous resumption of erections, probably through the improvement of endothelial function, but direct evidences to confirm this hypothesis are required.
