Importance: Guidelines recommend deferral of testing for symptomatic people with suspected coronary artery disease (CAD) and low pretest probability. To our knowledge, no randomized trial has prospectively evaluated such a strategy.
Objective: To assess process of care and health outcomes in people identified as minimal risk for CAD when testing is deferred.
Background: Acute transmural ischemia should induce similar magnitude of wall motion abnormality (WMA) in both anterior myocardial infarction (AMI) and inferior (IMI). However, patients with AMI generally suffer more severe hemodynamic compromise.
Methods: This retrospective study compared WMA's in ST segment elevation MI patients undergoing primary reperfusion and subsequent cardiac MRI.
Background: Bipolar disorder is a chronic mood disorder with episodic progress and high relapse rate. Growing evidence suggests that individuals with bipolar disorder display cognitive impairment which persists even throughout periods of symptom's remission.
Method: 137 bipolar patients met the inclusion criteria (depressive episode: DSM-IV-TR criteria for major depressive episode, HAMD score ≥17; manic/hypomanic episode: DSM-IV-TR criteria for manic/hypomanic episode, YMRS score ≥12, euthymic: 6 months of remission, HAMD score ≤8, YMRS score ≤6; and mixed: DSM-IV-TR criteria for mixed episode, HAMD score >8 and YMRS score >6) and were therefore enrolled in the study.
Objectives: The aim of this non-interventional, investigator driven study was to assess the functionality of patients with major depression under treatment with agomelatine in real life clinical practice.
Material And Methods: The study was multicenter, non-interventional and evaluated the functionality of the adult patients with a DSM-IV diagnosis of MDD (single or recurrent episode and no treatment in the previous 6 months). It took place in Romania and it was a 10-weeks study.
Objectives: The purpose of this study was to evaluate the validity of estimates of glomerular filtration rate (eGFR) for assessing serial changes in renal function after renal artery stenting.
Background: eGFR are unreliable for assessing serial renal function in patients with atherosclerotic renal artery stenosis (RAS). eGFR have not been validated for assessment of serial renal function after renal artery stenting.
Background: Non-high density lipoprotein cholesterol (non-HDL-C) goal attainment per Adult Treatment Panel III (ATP III) guidelines remains low.
Objective: To understand gaps in knowledge and practices of physicians-in-training (internal medicine, family medicine, cardiology, endocrinology) towards non-HDL-C.
Methods: A survey based on a conceptual model to assess the trainee's knowledge, attitudes, and practice regarding non-HDL-C was developed and administered to physicians-in-training (n = 655) at 26 training programs in the United States.
Objective: The goals of this study were to determine: 1) if the CHADS(2) score correlates with left atrial (LA) or left atrial appendage (LAA) thrombus on pre-cardioversion transesophageal echocardiography (TEE) in nonvalvular atrial fibrillation (NVAF); and 2) what, if any, components of the CHADS(2) score are most important in predicting LA/LAA thrombus.
Background: It is unknown if CHADS(2) score, a marker of thromboembolic risk in NVAF, accurately predicts LA/LAA thrombus on pre-cardioversion TEE.
Methods: We retrospectively studied patients undergoing precardioversion TEE for NVAF at a tertiary hospital.

Idiopathic dilated cardiomyopathy (IDCM) is the term used to describe a group of myocardial diseases of unknown cause whose common clinical presentation is heart failure. The prevalence of IDCM is estimated to be between 7 and 13% of patients with systolic heart failure. Throughout medical history, several nutrient-deficient states have been identified as the root cause of IDCMs, Keshan's disease being one such example, where selenium deficiency-induced heart failure is now well documented.

The currently available treatment options for patients with severely symptomatic CLI include bypass surgery and arterial revascularization. Percutaneous transluminal angioplasty for CLI is shown to be as effective as bypass surgery at high-volume centers, and it also offers a less invasive alternative, leading to quicker patient recovery times and lower short-term costs.

The purpose of this study was to evaluate the validity of GFR estimates in patients with atherosclerotic RAS.
Methods And Results: Serum creatinine (SCr) and (125)I-iothalamate GFR (I-GFR) were measured in patients with RAS.
Proteinuria, defined as urine protein excretion greater than 300 mg over 24 h, is a strong and independent predictor of increased risk for all-cause and cardiovascular mortality in patients with and without diabetes. Proteinuria is a sign of persistent dysfunction of the glomerular barrier and often precedes any detectable decline in renal filtration function. Measurement of proteinuria is important in stratifying the risk for cardiovascular disease and chronic kidney disease progression.

This results in an open-reading-frame shift that produces a translation stop codon and ultimately a truncated protein, termed DeltaFosB. In vitro splicing assays with control and mutated transcripts generated from a fosB mini-gene construct indicated a CU-rich sequence at the 3' end of intron 4 (I4) plays an important role in regulating fosB pre-mRNA splicing due to its binding of polypyrimidine tract binding protein (PTB).

Background: In diabetes, augmented cardiac sympathetic tone and abnormal MBF regulation may predispose to myocardial injury and enhanced cardiac risk.
Methods: Subject groups comprised healthy controls (C) (n = 10), healthy diabetic subjects (DC) (n = 12), and diabetic subjects with very early diabetic microangiopathy (DMA+) (n = 16).
Alterations in cyclooxygenase (COX) pathway activity have been implicated in the pathogenesis of experimental diabetic neuropathy (EDN). These studies explore the relationships between COX-mediated and acetyl-L-carnitine (ALC)-sensitive defects that contribute to functional, metabolic, and vascular abnormalities of EDN. The effects of nonselective COX inhibition with flurbiprofen were contrasted with selective COX-2 inhibition with meloxicam, administered alone and in combination with ALC in nondiabetic (ND) and streptozotocin-induced diabetic (STZ-D) rats.
