A case-control study of erectile dysfunction among men diagnosed with panic disorder.

The association between panic disorder and erectile dysfunction (ED) among men was examined in the Integrated Healthcare Information Services National Managed Care Benchmark Database (IHCIS). The IHCIS is a fully de-identified, HIPAA compliant database and includes complete medical history for more than 17 million managed care lives; data from more than 30 US health plans, covering seven census regions; and patient demographics, including morbidity, age and gender. A total of 60,949 ED cases and 243,796 controls were included for analysis. Unconditional logistic regression analyses were first performed to assess the crude risk of ED, and adjusted risks of ED that accounted for comorbid conditions and comedications. A second set of analyses measured the crude and adjusted risks after restricting the patient population to men who were diagnosed with panic disorder at least 1 month prior to an ED diagnosis. In the first set of analyses, men with panic disorder were observed to have more than a two-fold increase in risk for ED (OR=2.29, 95% CI=2.03, 2.58). After adjusting for comorbid conditions, a 52% increase in risk of ED was observed (OR=1.52, 95% CI=1.34, 1.72). Following subsequent adjustment for comorbidities and comedications, a 33% increased risk of ED was detected (OR=1.33, 95% CI=1.17, 1.51). In the second set of analyses studying panic disorder that preceded ED, only a 13% higher risk was noted (OR=1.13, 95% CI=0.97, 1.31). However, after adjusting for comorbid conditions, a 25% reduction in risk was observed (OR=0.75, 95% CI=0.64, 0.88). A 35% risk reduction was seen after adjusting for comorbidities and comedications (OR=0.65, 95% CI=0.56, 0.77).

Should erectile dysfunction be considered as a marker for acute myocardial infarction? Results from a retrospective cohort study.

The association between erectile dysfunction (ED) and acute myocardial infarction (AMI) among men was examined in the Integrated Healthcare Information Services National Managed Care Benchmark Database (IHCIS). The IHCIS is a fully de-identified, HIPAA-compliant database and includes complete medical history for more than 17 million managed care lives; data from more than 30 US health plans, covering seven census regions; and patient demographics, including morbidity, age and gender. A total of 12,825 ED patients and an equal number of male patients without ED were included in the retrospective cohort study. Logistic regression analyses were performed to assess the adjusted risk of AMI that accounted for age at ED diagnosis, smoking, obesity and medications including ACE inhibitors, beta blockers and statins. The cohort of men with ED were observed to have a two-fold increase in the risk for AMI (OR=1.99, 95% CI=1.17, 3.38) after adjusting for age at ED diagnosis, smoking, obesity, and use of ACE inhibitors, beta blockers and statins. Some evidence of a possible trend toward increased risk was detected by age group. After controlling for the aforementioned covariates and compared to men 30-39 y of age, it was noted that patients 40-44 y of age were 3.8 times more likely to develop an AMI (OR=3.76, 95% CI=1.21, 11.7), 45- to 49-y-old men were also more than three times as likely to have an AMI (OR=3.14, 95% CI=1.03, 9.64), and 50- to 55-y-old patients had a four-fold increased risk of developing AMI (OR=4.04, 95% CI=1.39, 11.7). The risk becomes more pronounced with increasing age, indicating the need for cardiologists and internists to monitor ED patients who may not necessarily present with cardiovascular symptoms.

Is erectile dysfunction predictive of peripheral vascular disease?

The association between erectile dysfunction (ED) and peripheral vascular disease (PVD) among men was examined in the Integrated Healthcare Information Services National Managed Care Benchmark Database (IHCIS). The IHCIS is a fully de-identified, Health Insurance Portability and Accountability Act compliant database and includes complete medical histories for more than 17 million managed-care lives; data from more than 30 US health plans, covering seven census regions; and patient demographics, including morbidity, age and gender. A total of 12 825 ED patients and an equal number of male patients without ED were included in the retrospective cohort study. Logistic regression analyses were performed to assess the adjusted risk of PVD that accounted for age at ED diagnosis, smoking, obesity and medications including angiotensin converting enzyme (ACE) inhibitors, beta blockers and statins. The cohort of men with ED were observed to have a 75% increase in risk for PVD (odds ratio (OR) = 1.75, 95% confidence interval (CI) = 1.06, 2.90) after adjusting for age at ED diagnosis, smoking, obesity and use of ACE inhibitors, beta blockers and statins. Some evidence of a possible trend towards increased risk was detected by age group. After controlling for the aforementioned covariates and compared to men aged 30-39 years, it was noted that patients aged 40-44 years were 2.1 times more likely to develop PVD (OR = 2.07, 95% CI = 0.89, 4.81), 45-49-year-old men were also more than twice as likely to have PVD (OR = 2.32, 95% CI = 1.03, 5.22), and 50-55-year-old patients had a three-fold increased risk of developing PVD (OR = 3.00, 95% CI = 1.40, 6.43). The results of this study indicate that ED may serve as a marker for PVD. The risk becomes more pronounced with increasing age, indicating the need for cardiologists and internists to monitor ED patients who may not necessarily present with cardiovascular symptoms.
