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 ¼ 1.99, 95% CI ¼ 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 ¼ 3.76, 95% CI ¼ 1.21, 11.7), 45-to 49-y-old men were also more than three times as likely to have an AMI (OR ¼ 3.14, 95% CI ¼ 1.03, 9.64), and 50-to 55-y-old patients had a four-fold increased risk of developing AMI (OR ¼ 4.04, 95% CI ¼ 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.

The purpose of this study was to better understand the frequency and mechanisms of stroke recurrence after the stroke with no determined cause (NC). We prospectively studied consecutive patients with acute cerebral infarcts. We divided the patients into five groups (large artery disease [LAD], cardioembolism [CE], small artery disease [SAD], two or more causes [TMC], and NC) and registered recurrent strokes and prognosis for 1 year. Those in the NC group were compared with other subtypes. A total of 204 patients were included; 56 LAD, 22 CE, 62 SAD, 27 TMC, and 37 NC. During follow-up, there were 7 deaths and 31 first recurrent strokes. Patients of the NC group showed a significantly higher rate (30%) of recurrent stroke than those of other subtypes (LAD 16%; CE 14%; SAD 2%), and it was associated with the existence of mild stenosis (<50%) on relevant artery or the stenosis of greater than 50% on nonrelevant artery. Occlusive lesions other than significant stenosis of relevant artery may play an important role in the development of stroke recurrence in patients of the NC group. Therefore, from the therapeutic and prognostic point of view, the detection of such occlusive lesions in patients with cryptogenic stroke may be needed.

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.

Although LS on examination, SDIs on diffusion-weighted imaging, and a stable hospital course suggest lacunar stroke of benign course, our results indicate that the PAD group represents an intracranial type of LAD.

The clinical and radiologic stroke patterns were distinctively different between atherosclerotic MCA and ICA disease, suggesting different underlying pathogeneses.

Aims Previous studies from Western countries have been unable to demonstrate a relationship between insulin resistance and new-onset atrial fibrillation. We aimed to evaluate this relationship in the nondiabetic Asian population. Methods Between 2001–2003, 8175 adults (mean age 51.5 years, 53% women) without both existing atrial fibrillation and diabetes and with insulin resistance measures at baseline were enrolled and were followed by biennial electrocardiograms thereafter until 2014. We constructed multivariable-adjusted Cox proportional hazard models for risk of incident atrial fibrillation. Results Over a median follow-up of 12.3 years, 136 participants (1.89/1000 person-years) developed atrial fibrillation. Higher homeostasis model assessment of insulin resistance (HOMA-IR) was independently associated with newly developed atrial fibrillation (hazard ratio 1.61, 95% confidence interval 1.14–2.28). Atrial fibrillation development increased at the HOMA-IR levels approximately between 1–2.5, and then plateaued afterwards ( p = 0.031). Conclusion There is a significant relationship between insulin resistance and atrial fibrillation development independent of other known risk factors, including obesity in a nondiabetic Asian population.
