Background The prognostic value of Doppler-derived coronary flow velocity reserve (CFVR) of the left anterior descending coronary artery in patients with type 2 diabetes with preserved left ventricular systolic function and without flow-limiting stenoses on angiography remains undetermined. Methods The study sample consisted of 144 patients with type 2 diabetes (82 men; mean age 62 ± 10 years) with chest pain or angina-equivalent symptoms, no histories of coronary artery disease, and echocardiographic ejection fractions ≥ 50%. All patients underwent dipyridamole stress echocardiography with CFVR assessment of the left anterior descending coronary artery by transthoracic Doppler echocardiography and coronary angiography showing normal coronary arteries or nonobstructive coronary artery disease. Results Mean CFVR was 2.44 ± 0.57. On individual patient analysis, 109 patients (76%) had CFVR > 2, and 35 (24%) had CFVR ≤ 2. During a median follow-up period of 29 months (interquartile range, 14-44 months), 17 hard events (five deaths, 12 nonfatal myocardial infarctions) occurred. The annual hard-event rate was 13.9% in subjects with CFVR ≤ 2 and 2.0% in those with CFVR > 2. The annual event rate associated with CFVR ≤ 2 was significantly higher both in patients with left ventricular hypertrophy (P < 0001) and in those without left ventricular hypertrophy (P =.048). On Cox analysis, CFVR ≤ 2 (hazard ratio, 11.20; 95% confidence interval, 3.07-40.92), and male sex (hazard ratio, 7.80; 95% confidence interval, 1.74-34.97) were independent prognostic indicators, whereas nonobstructive coronary artery disease was not an independent predictor of outcomes. Conclusions Microvascular dysfunction before the occurrence of coronary artery involvement is a strong and independent predictor of outcomes in patients with type 2 diabetes. Vasodilator stress CFVR is a suitable tool to assess microvascular dysfunction in routine clinical practice. © 2014 by the American Society of Echocardiography. Source

We describe three cases of split median raphe of the penis (SMR) from our hospital newborn records from 2004 to 2013. One case was associated with median raphe cyst, one with skin hypochromia, and one with a scar-like aspect of the region of interest. SMR is thought to be the result of defective fusion of ectodermal tissue in the urethra and scrotum area or of defective growth of the perineal mesoderm around the urethra during gestation. Although SMR associated with other major penile congenital defects (epispadias, hypospadias, penile torsion, bifid scrotum, chordee) is common, isolated SMR is probably an underdiagnosed (although not rare) malformative condition. Recognizing SMR in a newborn may be of educational value to neonatologists because it leads to the search for and exclusion of the above-mentioned pathologic conditions. © 2014 Wiley Periodicals, Inc.

The "Cardio-Renal Syndrome" (CRS) is a disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. The general definition has been expanded to five subtypes reflecting the primacy of organ dysfunction and the time-frame of the syndrome: CRS type I: acute worsening of heart function (AHF-ACS) leading to kidney injury and/or dysfunction. CRS type II: chronic abnormalities in heart function (CHF-CHD) leading to kidney injury or dysfunction. CRS type III: acute worsening of kidney function (AKI) leading to heart injury and/or dysfunction. CRS type IV: chronic kidney disease (CKD) leading to heart injury, disease and/or dysfunction. CRS type V: systemic conditions leading to simultaneous injury and/ or dysfunction of heart and kidney. Different pathophysiological mechanisms are involved in the combined dysfunction of heart and kidney in these five types of the syndrome. © 2010 Springer Science+Business Media, LLC. Source

We reviewed patients with normal or near-normal coronary angiograms enrolled in the SPAM contrast stress echocardiographic diagnostic study in which 400 patients with chest pain syndrome of suspected cardiac origin with a clinical indication to coronary angiography were enrolled. Patients underwent dipyridamole contrast stress echocardiography (cSE) with sequential analysis of wall motion, myocardial perfusion, and Doppler coronary flow reserve before elective coronary angiography. Ninety-six patients with normal or near-normal epicardial coronary arteries were screened for the presence of 2 prespecified findings: severely tortuous coronary arteries and myocardial bridging. Patients were divided in 2 groups based on the presence (false-positive results, n = 37) or absence (true-negative results, n = 59) of reversible myocardial perfusion defects during cSE and compared for history and clinical and angiographic characteristics. Prevalence of severely tortuous coronary arteries (35% vs 5%, p <0.001) or myocardial bridging (13% vs 2%, p <0.05) was 7 times higher in patients who demonstrated reversible perfusion defects at cSE compared to those without reversible perfusion defects. No significant differences were found between the 2 groups for the main demographic variables and risk factors. Patients in the false-positive group more frequently had a history of effort angina (p <0.001) and ST-segment depression at treadmill electrocardiography (p <0.001). In conclusion, we hypothesize that patients with a positive myocardial perfusion finding at cSE but without obstructive epicardial coronary artery disease have a decreased myocardial blood flow reserve, which may be caused by a spectrum of causes other than obstructive coronary artery disease, among which severely tortuous coronary arteries/myocardial bridging may play a significant role. © 2011 Elsevier Inc.
