Abnormal noninvasive stress test (NIST) findings do not always correlate with angiographically significant (luminal obstruction ≥50%) coronary artery disease. Positive predictive value (PPV) of NIST in the real clinical practice is not well known. The goal of this retrospective study was to determine the PPV of NIST and assess the factors affecting PPV in a US community hospital. This study included all consecutive patients (n = 355) who underwent invasive coronary angiography after a positive NIST within ~1-year duration at our institution...

BACKGROUND: Accurate identification of patients at risk of major adverse cardiac events (MACE) places a substantial burden on emergency physicians (EPs). Bayesian nomogram for risk stratification in low- to intermediate-risk cardiovascular patients has not been investigated previously. OBJECTIVE: The objective of this study was to develop a comparative diagnostic model using Bayesian statistics for exercise treadmill test (ETT) and stress echocardiogram (ECHO) to calculate post-test diagnostic risk of MACE using HEART (history, electrocardiogram, age, risk factors, and troponin) risk score as predictor of pretest probability...

BACKGROUND: In plants, the shoot apical meristem (SAM) has two main functions, involving the production of all aerial organs on the one hand and self-maintenance on the other, allowing the production of organs during the entire post-embryonic life of the plant. Transcription factors, microRNA, hormones, peptides and forces have been involved in meristem function. Whereas phosphatidylinositol phosphates (PIPs) have been involved in almost all biological functions, including stem cell maintenance and organogenesis in animals, the processes in meristem biology to which PIPs contribute still need to be delineated...

One of the major issues in management of the acute coronary syndrome (ACS) is classification of patients with atypical presentation who have low risk of having a coronary episode at presentation. There have been multiple studies on the stratification of high risk patients and medical management of such cases, however, there is a sub-class of patients who do not fit any category. In this paper, we have looked at the current literature on stratification of patients based on the study tools available and the risk of having a coronary episode during the following year...

A 16-year-old male presented to the emergency department with chest pain after smoking a synthetic cannabinoid from a vape pen. He had rising troponin I levels, and his exercise stress echocardiogram showed distal apical and septal hypokinesis that resolved at six-month follow-up. This case report raises concern about cardiac ischemia related to synthetic cannabinoid abuse in the pediatric population in the current era of cannabis legalization.

BACKGROUND AND AIM: Cirrhotic cardiomyopathy (CCM) is associated with high mortality after transjugular intrahepatic portosystemic shunt (TIPS) and liver transplantation in patients with cirrhosis. There is no data about the prevalence or impact of CCM in Budd-Chiari syndrome (BCS). We assessed the prevalence of CCM in patients with BCS and its impact on outcome after radiological intervention. METHODS: Thirty-three consecutive patients with BCS (15 men) and 33 controls with hepatitis B-related cirrhosis (18 men, matched for Child-Pugh score) were evaluated with baseline electrocardiography (ECG), echocardiography (ECHO) and dobutamine stress ECHO, and ECG (DSE)...

OBJECTIVE: Fetal aortic stenosis (AS) imposes pressure load on the developing left ventricle (LV) and leads to derangements in myocardial structure and function via mechanisms that are not well characterized. METHODS: We compared amniotic fluid NT-BNP and troponin levels in fetuses with AS prior to fetal valvuloplasty and controls. We estimated correlations between NT-BNP and fetal echo parameters and identify NT-BNP cutoff associated with biventricular outcome RESULTS: Median NT-BNP level was higher in fetal AS than controls (3858 vs 1737 pg/mL, P < 0...

Patients who attempt intentional suicide suffer from physical or emotional stress. This situation might be an important factor that causes takotsubo cardiomyopathy. We retrospectively investigated the clinical features of Takotsubo cardiomyopathy in patients with acute poisoning. This study included patients who were admitted from January 2010 to December 2015 because of intentional poisoning by ingestion. Among these patients, we selectively collected data of patients who underwent an echocardiogram. We divided the patients into three groups according to the echocardiogram; the non-cardiomyopathy group, the global hypokinesia group, and the takotsubo cardiomyopathy group...

RATIONAL: Takotsubo cardiomyopathy (TCM) is a transient systolic dysfunction of the left ventricular apex without stenosis of coronary arteries and is induced by various psychological and physical factors. TCM sometimes causes lethal complications such as arrhythmia, thrombogenesis, and even cardiac rupture, and thus it should be diagnosed appropriately and managed carefully. Intensive care unit (ICU) patients are exposed to overstress during the treatment process and therefore can are at potential risk for TCM...

BACKGROUND AND OBJECTIVE: It is hypothesized that diminished cerebral vascular resistance or the "brain sparing effect" is associated with fetuses with complex congenital heart defects (CHD) and may affect their neurodevelopmental outcome. An alternative explanation is that it is related to the location, cardiac output, pressure, and resistance in left heart obstructive CHDs. We sought to determine the effects of various left and right heart obstructive defects on the cerebral and placental hemodynamics and to evaluate the utility of these variables for the assessment and prognosis of CHDs...

Little is known of the importance of echocardiographic measures of resting systemic vascular resistance (SVR), cardiac output, and diastolic function in the development of a hypertensive response during dobutamine stress echocardiography. We performed a retrospective review of 325 subjects who underwent stress echocardiography and a resting echocardiogram on the same day. Logistical regressions were performed to determine associations between hypertensive response to each type of stress test and clinical and hemodynamic measurements obtained by transthoracic echocardiography...

BACKGROUND: Evaluation and disposition of low-risk chest pain (CP) patients in the emergency department (ED) is time consuming and expensive. Low-risk CP often results in hospital admission to rule out myocardial infarction, which leads to additional costs and delays. OBJECTIVE: Our aim was to assess whether an immediate exercise stress echocardiogram (IESE) in the ED will allow safe, efficient, and cost-effective evaluation and discharge of patients with low-risk CP...

OBJECTIVES: This study sought to investigate the association of left ventricular (LV) untwisting rate (UT) and E/e' ratio with the response of exercise capacity to spironolactone in heart failure with preserved ejection fraction (HFpEF). BACKGROUND: In most patients with HFpEF, LV filling abnormalities represent a central component in the development of dyspnea. LV diastolic filling is determined by the interplay of passive (LV stiffness and myocardial collagen content, reflected by E/e' ratio) and active myocardial properties (UT, a precursor to isovolumic pressure decay and contributor to diastolic suction)...

Background: Patients with cirrhosis who develop Spontaneous Bacterial Peritonitis (SBP) suffer from cirrhotic cardiomyopathy which is characterized by impaired contractility in response to stress despite a relatively normal resting cardiac output. We hypothesized that electrocardiographic and echocardiographic information would help prognosticate patients developing SBP in addition to existing scoring systems. Methods: Cirrhotic patients admitted to Einstein Medical Center from 01/01/2005 to 6/30/2012 for SBP, and did not receive a transplant within one year, were included...
