BACKGROUND Hypertrophic cardiomyopathy (HCM) is a common inherited cardiac disease characterized by varying degrees of left ventricular outflow tract obstruction. In a large cohort, we compare the outcomes among 3 different hemodynamic groups. METHODS AND RESULTS We prospectively enrolled patients fulfilling standard diagnostic criteria for HCM from January 2005 to June 2015. Detailed phenoty...

The purpose of this study was to assess the outcome of nonobstructive (or non-flow-limiting) residual dissection (RD) after percutaneous coronary intervention. Results of 124 consecutive native coronary lesions with angiographic nonobstructive RD in 97 patients (RD group) were compared with outcomes of 124 lesions without RD in 100 patients (non-RD group), whose characteristics were matched wit...

A 38-year-old African American woman presenting with acute abdominal pain and nonobstructive renal failure was found to have an enlarged fibroid uterus. A differential for sepsis was considered. Lab evaluation revealed an elevated creatinine and myoglobin level at 3.9 mg/dL and 2140 ng/mL, respectively. Ongoing hemodynamic instability mandated surgery for acute abdomen. A 25 cm fibroid uterus w...

PURPOSE We examined the relationship between L-PGDS (lipocalin-type prostaglandin D synthase) levels in seminal plasma and the presence or absence of obstruction in the male seminal tract. MATERIALS AND METHODS Semen samples were collected and analyzed from 1) 10 patients with normal semen parameters, 2) 9 with obstructive azoospermia, 3) 20 after vasectomy and 4) 14 with nonobstructive azoos...

BACKGROUND Troponin elevation is a risk factor for mortality in patients with non-ST-segment-elevation acute coronary syndromes. However, the prognosis of patients with troponin elevation and nonobstructive coronary artery disease (CAD) is unknown. Our objective was therefore to evaluate the impact of nonobstructive CAD in patients with non-ST-segment-elevation acute coronary syndromes and trop...

UNLABELLED INTRODUCTION Excessive fluid intake can lead to water intoxication, electrolyte abnormalities, exacerbation of heart failure and anatomical changes in the urinary tract that may present diagnostic and therapeutic challenges for patients and physicians. Although the development of nonobstructive hydronephrosis is recognized in patients with central and nephrogenic diabetes insipidu...

INTRODUCTION Our aim was to evaluate the predictive values of factors that indicate successful sperm retrieval in men with nonobstructive azoospermia. MATERIALS AND METHODS We evaluated 85 infertile men with nonobstructive azoospermia who underwent multiple bilateral testicular biopsies. Factors including age, infertility period, surgical history, testicular volume, testicular consistency, se...

OBJECTIVE The usefulness of coronary computed tomography angiography (CTA) for the evaluation of coronary artery disease (CAD) in patients with diabetes is ambiguous. We therefore performed a meta-analysis of studies reporting event rates and hazard ratios (HR) to determine the prognostic value of CTA in this patient population. RESEARCH DESIGN AND METHODS We searched PubMed and Embase up to ...

BACKGROUND There is a paucity of data on the need for optimal medical therapy (OMT) in nonobstructive coronary artery disease . We sought to understand if there was variation in the use of OMT between hospitals for patients with nonobstructive coronary artery disease, the factors associated with such variation, and its clinical consequences. METHODS AND RESULTS Using a population-level clinic...
