<h3>Context</h3>Depressive symptoms predict adverse cardiovascular outcomes in patients with coronary heart disease, but the mechanisms responsible for this association are unknown.<h3>Objective</h3>To determine why depressive associated an increased risk of events.<h3>Design and Participants</h3>The Heart Soul Study is a prospective cohort study 1017 outpatients stable disease followed up mean (SD) 4.8 (1.4) years.<h3>Setting</h3>Participants were recruited between September 11, 2000,...
Because acute segmental wall motion abnormalities (SWMAs) of the left ventricle are highly sensitive and specific indicators myocardial ischemia, this study compared incidence significance as detected by two-dimensional transesophageal echocardiography surface electrocardiography, during anesthesia surgery in patients at high risk ischemia. During surgery, 24 50 studied had new SWMAs, whereas only six ST segment changes. All with changes also SWMAs: three instances, SWMAs occurred before...
To determine whether pulmonary venous flow and mitral inflow measured by transesophageal pulsed Doppler echocardiography can be used to estimate mean left atrial pressure (LAP), we prospectively studied 47 consecutive patients undergoing cardiovascular surgery. We correlated variables of with simultaneously obtained LAP changes in or artery catheters. Among the variables, systolic fraction (i.e., velocity-time integral expressed as a sum early diastolic integrals) most strongly (r = -0.88)....
Background —Determinants of left atrial (LA) reservoir function and its influence on ventricular (LV) have not been quantified. Methods Results —In an open-pericardium, paced (70 90 bpm) pig model LV regional ischemia (left anterior descending coronary constriction), with high-fidelity LV, LA, RV pressure recordings, we obtained the LA area 2D automated border detection echocardiography, pressure-area loops, Doppler transmitral flow. We calculated τ, relaxation (a−x difference divided by...

BACKGROUND: A subset of patients with mitral valve prolapse (MVP), a highly heritable condition, experience sudden cardiac arrest (SCA) or death (SCD). However, the inheritance phenotypic imaging features arrhythmic MVP remains unknown. METHODS: We recruited 23 probands, including 9 SCA/SCD and 14 frequent/complex ventricular ectopy. Participants underwent interviews, 2-dimensional speckle-tracking echocardiography, 48-hour Holter/event monitoring. Each individual was categorized as having...
Identification of individuals at high risk for cardiovascular events is important the optimal use primary and secondary prevention measures.To determine whether plasma levels amino terminal fragment prohormone brain-type natriuretic peptide (NT-proBNP) predict or death independent other available prognostic tests.Prospective cohort study (2000-2002) 987 in California with stable coronary heart disease Heart Soul Study, who were followed up a mean 3.7 (range, 0.1-5.3) years.The association...
To determine the feasibility of noninvasive determination right ventricular systolic pressure (RVSP) during a graded-exercise protocol, saline contrast-enhanced Doppler echocardiography tricuspid insufficiency was performed in 36 patients with chronic lung disease and 12 normal controls. In pulmonary disease, symptom-limited, incremental supine bicycle exercise pulse oximetry were on off high-flow oxygen. Technically adequate studies initially obtained 20 (56%) at rest 14 (39%) exercise;...
We evaluated scintigraphy and echocardiography for the diagnosis of right ventricular (RV) infarction. Of 26 patients with acute transmural myocardial infarction (MI), six inferior MI had abnormal radionuclide uptake localized to RV free wall on infarct or segmental akinesis gated radioangiography both. These involvement (group I) were compared remaining nine II) 11 anterior III). RV/LV area ratios determined radioangiographically significantly greater in group I than II diastole systole....
In patients with symptoms of heart failure, elevations in B-type natriuretic peptide (BNP) accurately identify ventricular dysfunction. However, BNP levels are not specific for dysfunction who do have overt suggesting that other cardiac processes such as myocardial ischemia may also cause BNP.To determine whether associated ischemia, we measured plasma before performing exercise treadmill testing stress echocardiography outpatients stable coronary disease. Of the 355 participants, 113 (32%)...
<h3>Objective.</h3> —To describe and compare with standard cardiopulmonary resuscitation (CPR) in humans a new form of CPR that involves both active compression decompression the chest. <h3>Design.</h3> —Patients cardiac arrest whom advanced life support failed were randomized to receive 2 minutes either or compression-decompression (ACD) using custom, hand-held suction device, followed by alternate technique. The ACD device was applied midsternum used perform according guidelines American...
