Interchangeability of activated clotting time values across different point-of-care systems.

Journal Article Am J Cardiol · May 1, 2012 Significant variability in activated clotting time (ACT) measurement exists based on the type of point-of-care system used. We sought to determine the degree of agreement in ACT measurements by the Hemochron Response and the Hemochron Signature Elite Whole ... Full text Link to item Cite

Current practice for determining pulmonary capillary wedge pressure predisposes to serious errors in the classification of patients with pulmonary hypertension.

Journal Article Am Heart J · April 2012 BACKGROUND: Accurate measurement of left ventricular filling pressure is important to distinguish between category 1 pulmonary arterial hypertension (PAH) and category 2 pulmonary hypertension (PH) from left heart diseases (PH-HFpEF). We hypothesized that ... Full text Link to item Cite

Inaccuracy of doppler echocardiographic estimates of pulmonary artery pressures in patients with pulmonary hypertension: Implications for clinical practice

Journal Article Chest · May 1, 2011 Background: Recent studies suggest that Doppler echocardiography (DE)-based estimates of pulmonary artery systolic pressure (PASP) may not be as accurate as previously believed. We sought to determine the accuracy of PASP measurements using DE compared wit ... Full text Cite

Journal Article J Invasive Cardiol · February 2011 We present the case of a gentleman who presented to our hospital with recurrent episodes of sudden cardiac death treated initially with cardioversion. Immediate coronary angiography revealed a 7 mm aneurysm in the proximal left coronary artery. Using intra ... Link to item Cite

Echocardiographic quantification of left ventricular mass: prognostic implications.

Journal Article Curr Cardiol Rep · May 2010 Left ventricular hypertrophy (LVH) has been shown to be an independent risk factor for adverse cardiac and cerebrovascular events. Despite this well-known association, the lack of a standardized approach for the quantification and the monitoring of LVH reg ... Full text Link to item Cite

Clinical methods for the detection and management of left ventricular hypertrophy.

Journal Article Indian Heart J · 2010 Left ventricular hypertrophy (LVH) has been shown to be an independent risk factor for adverse cardiac and cerebrovascular events.
