Heart failure studies have suggested important differences between women and men both in heart failure etiology and in survival. Clinical trials and long-standing perceptions of the typical heart failure patient have related far more to men than to women, while more women than men in the United States may be hospitalized with heart failure. The goal of this study was to analyze ADHERE Registry data, the largest database of acute decompensated heart failure (ADHF) patient hospitalizations available, to gain insight into the effect of gender on medical history, clinical characteristics, and discharge counseling. This preliminary study analyzed the 85,617 ADHF hospitalizations in the ADHERE Registry as of October 2003, with 44,340 (52%) women and 41,276 (48%) men included. Women were significantly older (mean age 74.6 +/- 13.7 years) than men (mean age 70.2 +/- 13.9 years, P < .0001). Women were more likely to have a history of hypertension (75% vs. 69%, P < .0001) and a systolic blood pressure > 140 mm Hg (56% vs. 44%, P < .0001). History of coronary artery disease was more common in men (64% vs. 51%, P < .0001). Other risk factors for atherosclerosis, including smoking (17% vs. 10%, P < .0001) and hyperlipidemia (37% vs. 32%, P < .0001), were also more common in men. Men had a significantly lower mean left ventricular ejection fraction (32.9%, N = 30,831) than women (42.1%, N = 29,744); 51% of women had preserved left ventricular function (EF > 40%) compared to only 28% of men (P < 0.0001). At discharge, adherence to 3 of the 4 JCAHO standardized measures of quality of care far heart failure patients were documented more frequently for men than for women. A significantly smaller proportion of women received discharge instructions on management of diet, weight, and medications (30.1% vs. 32.8%); received or were scheduled for assessment of left ventricular function (81.5% vs. 85.6%); or were discharged with an angiotensin converting enzyme inhibitor prescription if appropriate (72.6% vs. 73.9%). Real-world data from the ADHERE Registry may lead to better recognition of the signs and symptoms of heart failure in women, increase the proportion of women who are correctly diagnosed, and may help to support gender-specific considerations in heart failure guidelines.

It is unclear whether patients with coronary artery disease (CAD) and diabetes mellitus (DM) can make comprehensive lifestyle changes that produce similar changes in coronary risk factors and quality of life compared with patients with CAD and without DM. We examined medical characteristics, lifestyle, and quality of life by diabetic status and gender in the Multicenter Lifestyle Demonstration Project (MLDP), a study of 440 nonsmoking patients with CAD (347 men, 55 with DM; 15.9%; 93 women, 36 with DM; 38.7%). Patients met in groups to improve lifestyle (plant-based, low-fat diet; exercise; stress management) for 1 year. Follow-ups were conducted at 3 and 12 months. At baseline, body mass and systolic blood pressure were significantly higher among patients with DM. Men with DM had a worse medical history (e.g., hypertension, hyperlipidemia, and family history of CAD) than did those without DM. Patients with DM, especially women, reported poorer quality of life than did patients without DM. The 2 groups of patients were able to adhere to the recommended lifestyle, as demonstrated by significant improvements in weight (mean -5 kg), body fat, low-density lipoprotein cholesterol, exercise capacity, and quality of life. No significant changes in triglycerides and high-density lipoprotein cholesterol were noted. By the end of 12 months, improvements in glucose-lowering medications (i.e., discontinuation or a change from insulin to oral hypoglycemic agents) were noted for 19.8% (n = 18) of patients with DM. In conclusion, patients with CAD and DM are able to follow a comprehensive lifestyle change program and show similar improvements in coronary risk factors and quality of life as those without DM.

Prevalence of hyperhomocysteinemia (HHC) in a sample of male population (n=84, age 50-64 year) of Novosibirsk assessed in the framework of the international project "Determinants of cardio-vascular diseases in the Eastern Europe: multicentral cohort research" during winter-spring period of vitamin deficiency was 50%. In 90.5% of cases HHC was moderate (15-30 micromol/l) and in 9.5% of cases -- medium (30-100 micromol/l). No correlations or independent associations were found between homocysteine blood level and CHD, as well as main risk factors (hyperlipidemia, hypertension, smoking and excessive body weight). No cases of CHD were registered among men with medium HHC. Homocysteinemia correlated positively with age, history of stroke, and negatively -- with alpha-tocopherol concentration in LDL. Men with medium HHC compared with those with normohomocysteinemia had higher systolic and diastolic blood pressure and 29% lower alpha-tocopherol concentration in LDL.

Measurement of coronary artery calcium (CAC) has been proposed as a screening tool, but CAC levels may differ according to race and gender. Racial/ethnic and gender distributions of CAC were examined in a randomly selected cohort of 60- to 69-year-old healthy subjects. Demographic, race/ethnicity (R/E), and clinical characteristics and assessment of CAC were collected. There were 723 white/European, 105 African-American, 73 Hispanic, and 67 East Asian subjects (597 men, 369 women) included in this analysis. Men had a significantly higher prevalence of any CAC (score>10) than women (76% vs 41%; p<0.0001). For men, the unadjusted odds of having any CAC was 2.2 (95% confidence interval [CI] 1.3 to 3.8) for whites compared with African-Americans. For women, CAC scores were not significantly different across ethnic groups. After adjustment for coronary risk factors, African-American and East Asian R/E remained associated with a lower prevalence of CAC in men (adjusted odds ratios [ORs] 0.33 and 0.47, respectively), as well as older age (OR 1.2, 95% CI 1.1 to 1.3), known hyperlipidemia (OR 1.7, 95% CI 1.1 to 2.7), and history of hypertension (OR 2.2, 95% CI 1.4 to 3.3). In women, Asian R/E (OR 2.5, 95% CI 1.1 to 5.7), history of smoking (adjusted OR 2.8, 95% CI 1.3 to 6.1), and known hyperlipidemia (adjusted OR 2.0, 95% CI 1.3 to 3.1) were associated with a higher prevalence of CAC independent of other risk factors. In conclusion, our data indicate that the presence of CAC varied significantly across selected race/ethnic groups independent of traditional cardiovascular risk factors.

Biliary tract cancers, encompassing the gallbladder, extrahepatic bile duct, and ampulla of Vater, are uncommon yet highly fatal malignancies. Gallstones, the primary risk factor for biliary cancers, are linked with hyperlipidemia. We examined the associations of 12 single nucleotide polymorphisms of five genes in the lipid metabolism pathway with the risks of biliary cancers and stones in a population-based case-control study in Shanghai, China. We included 235 gallbladder, 125 extrahepatic bile duct, and 46 ampulla of Vater cancer cases, 880 biliary stone cases, and 779 population controls. Subjects completed an in-person interview and gave blood. Genotyping was conducted by TaqMan assay using DNA from buffy coats. The effects of APOE IVS1+69 (rs440446) and APOB IVS6+360C>T (rs520354) markers were limited to men. Men carrying the G allele of APOE IVS1+69 had a 1.7-fold risk of stones [95% confidence interval (95% CI), 1.2-2.4], a 1.8-fold risk of gallbladder cancer (95% CI, 1.0-3.3), a 3.7-fold risk of bile duct cancer (95% CI, 2.0-7.0), and a 4-fold risk of ampullary cancer (95% CI, 1.4-12.4). Male carriers of the T allele of APOB IVS6+360C>T had a 2-fold risk of bile duct cancer (95% CI, 1.2-3.4). The APOB T-T haplotype (APOB IVS6+360C>T, EX4+56C>T) was associated with a 1.6-fold risk of bile duct cancer (95% CI, 1.1-2.3). Male and female carriers of the T allele of LDLR IVS9-30C>T (rs1003723) had a 1.5-fold risk of bile duct cancer. Our findings suggest that gene variants in the lipid metabolism pathway contribute to the risk of biliary tract stones and cancers, particularly of the bile duct.

Because sildenafil citrate is a treatment, not a cure, for erectile dysfunction (ED), many men may choose to use it for an extended period. Men with ED who had previously completed 1 of 4 double-blind trials with short-term open-label extension (combined duration, 0.9-1.2 years) were eligible for this 4-year, open-label, extension study, which assessed the safety and effectiveness of flexible doses (25, 50, and 100 mg sildenafil) used as needed. Adverse events that were serious or led to dosing changes or discontinuation (temporary or permanent) were recorded. Many of the 979 participants (mean age, 58 [range, 27-82] years; mean ED duration, 4.5 years) had concomitant hypertension (28%), diabetes (22%), or hyperlipidemia (14%). Overall, 37 (3.8%) had treatment-related adverse events (none serious) requiring dosage change or discontinuation and 62 (6.3%) discontinued because of insufficient response. At each yearly assessment, more than 94% of participants responded affirmatively to the questions: "Are you satisfied with the effect of treatment on your erections?" and "If yes, has treatment improved your ability to engage in sexual activity?" These results argue against the loss of tolerability or the development of tachyphylaxis over a prolonged period of as needed, flexible-dose sildenafil treatment of men with ED.

Prostate cancer is the leading cancer diagnosis and second leading cause of cancer-related mortality for men in the United States. Due to the increased prevalence of prostate cancer in men older than 50 years, men at risk for prostate cancer represent the same population of men who are at greatest risk for metabolic syndrome, diabetes mellitus, and coronary artery disease (CAD). In addition to risk factors for CAD that are applicable to the general population, men with prostate cancer can be at increased risk for CAD due to long-term androgen deprivation therapy (ADT) administered as treatment for prostate cancer. Men undergo ADT by medical (drug therapy) or surgical (castration) means. Luteinizing hormone-releasing hormone (LHRH) agonists are the primary drug therapies used for ADT. Commercially available LHRH agonists are goserelin, histrelin, leuprolide, and triptorelin. Body composition changes, hyperlipidemia, insulin resistance, metabolic syndrome, and acute coronary syndrome are all reported adverse effects of ADT, which are consequences of reduced levels of circulating testosterone. Metabolic and body composition changes associated with ADT arise within months of beginning medical ADT and persist after discontinuation of therapy. To better understand the increased risk of metabolic syndrome, diabetes, and heart disease in patients undergoing ADT for prostate cancer, we performed a MEDLINE search (1986-2008) to identify pertinent studies and reports. Additional citations were obtained from the articles retrieved from the literature search. We found that the increased risk for serious cardiovascular disease becomes evident within months of beginning ADT. Pharmacists should provide counseling to these patients on primary disease prevention. Men receiving ADT should be monitored routinely for signs and symptoms of metabolic syndrome, diabetes, and CAD. Healthy lifestyle practices should be encouraged, and physical therapy should be considered for these patients.

Erectile dysfunction (ED) is the inability to attain and/ or maintain an erection sufficient for satisfactory sexual performance. The prevalence of ED among elderly men is 52%, and it is associated with preventable and treatable cardiovascular conditions, such as diabetes mellitus, hyperlipidemia, hypertension and smoking. Treating these conditions may prevent cardiovascular diseases and ED. Nevertheless, large-scale studies regarding the prevalence of ED among young men has never been conducted, although prevention should be performed in younger ages. A unique screening examination, including a sexual questionnaire has been conducted in Israel since 2001. Men who are suspected of ED, according to this questionnaire, are referred to a sexual clinic for consultation and treatment. In this review, we present several studies based on this database. Our main findings: ED is prevalent in young men and is associated with diabetes mellitus, hypertriglyceridemia, sleeping disorders and periodontal diseases. These findings stress the importance of incorporating a sexual questionnaire in screening examinations.

The prevalence of erectile dysfunction (ED) increases with age. ED has organic aetiologies and is associated with other clinical comorbidities. Men with ED are more likely to have: cardiac disease, diabetes, hypercholesterolaemia, angina, hypertension, prostate disease and depression. Similarly, men with these conditions are more likely to have ED. It is believed that vasculogenic ED shares a common aetiology with coronary artery disease, including hyperlipidaemia, diabetes and hypertension. Taking a careful history of onset, duration and associated symptoms may reveal possible causes of ED. Past medical history, disease control, trauma and medication use can provide vital information. ED patients with a sedentary lifestyle should be encouraged to exercise. In obese men, weight loss of 10% or more can improve IIEF score. Regular exercise, healthy diet, smoking cessation, limiting alcohol intake and avoiding recreational drugs can reduce the risk of, or improve, ED. It is important to differentiate between patients suffering from nocturnal frequency, enuresis or nocturnal polyuria as the causes and treatments for each of these conditions are different. Reducing fluid intake after 6 pm and avoiding alcohol and/or caffeine at night may reduce nocturnal voiding. Anticholinergics can decrease bladder overactivity. An improvement in nocturia and nocturia bother score have been shown after administration of oral melatonin. Nocturnal enuresis can often be the only symptom of high-pressure chronic retention which is prevalent in older men. It is important to recognise this condition as treatment can prevent further renal impairment. In nocturnal polyuria the urine output at night is more than a third of the total daily urine output. If conservative measures are not successful, in the absence of heart failure, a low-dose diuretic in the afternoon can help the kidneys get rid of the fluid before bedtime.

This study was aimed to investigate the influence of coital frequency and masturbation on erectile dysfunction (ED) in Chinese patients. A total of 332 male outpatients with or without ED and volunteers were recruited from Zhongnan Hospital, Wuhan University, China. ED was assessed by using the five-item International Index of Erectile Function scale and the frequency of intercourse by patients' self-report. After adjusting for lifestyle factors and diseases-related factors, the analyses showed that coital and masturbation in a certain frequency tended to decrease the risk of ED. Men reporting intercourse once a week had lower risk of ED than those did less than once a week, with age, hyperlipidemia, hypertension, diabetes, body mass index, smoking, and drinking as covariates (P=0.67, adjusted odds ratio [OR] = 0.84; 95% confidence interval [CI]: 0.37-1.88). For those reporting coital frequency two times per week and three or more times per week, there were 63% (adjusted OR = 0.37; 95% CI: 0.18-0.77) and 85% (adjusted OR = 0.15; 95% CI: 0.07-0.35) lower risk of ED than those reporting intercourse frequency less than once per week, respectively (P<0.05). Results indicated that maintaining a regular frequency of intercourse can reduce the risk of ED for males aged among 30 to 75 years.
