Disease relevance of Echocardiography

• Of the 100 patients without perioperative infarction detected by echocardiography, 19 had elevations of MB creatine kinase, and 1 had a slight elevation of cardiac troponin I. CONCLUSIONS [1].
• CONCLUSION: In men with stable CAD, sildenafil had no effect on symptoms, exercise duration, or presence or extent of exercise-induced ischemia, as assessed by exercise echocardiography [2].
• The effect of terbutaline sulfate on left ventricular size and performance was studied by M-mode echocardiography in pregnant women with premature labor [3].
• OBJECTIVE: To evaluate cardiovascular status and the prevalence of valvular abnormalities, as assessed by clinical cardiovascular parameters and echocardiography, in patients treated for obesity with dexfenfluramine or phentermine/fenfluramine [4].
• We studied 25 patients with anterior myocardial infarction and two with congestive cardiomyopathy to evaluate two-dimensional echocardiography in the diagnosis of left ventricular thrombi [5].

Psychiatry related information on Echocardiography

• Transoesophageal echocardiography (TOE) has gained widespread acceptance among cardiac anaesthetists as a tool to facilitate peri-operative decision-making [6].

High impact information on Echocardiography

• Of these 846 patients, 173 had positive results on dobutamine echocardiography [7].
• METHODS: We performed echocardiography in 36 patients before and several times after the ingestion of either 50 ml of 40 percent ethanol or an isocaloric placebo with the aroma of rum [8].
• We performed echocardiography prospectively 4.9 +/- 0.7 years apart (mean +/- SD), in 74 patients with systemic lupus erythematosus [9].
• The detection of ductal constriction in 7 of the 14 fetuses by echocardiography led to the discontinuation of indomethacin [10].
• To examine the importance of left ventricular chamber size in determing the response to vasodilator therapy, we performed echocardiography in 40 patients with chronic refractory heart failure before they were treated with oral hydralazine [11].

Chemical compound and disease context of Echocardiography

• MEASUREMENTS: Target organ abnormalities were measured by echocardiography and arterial ultrasonography in 61 patients with white coat normotension, 234 with sustained normotension (normal clinic and ambulatory blood pressure), and 64 with sustained hypertension [12].
• METHODS AND RESULTS: Thirty-four patients with stable coronary disease and regional dysfunction underwent dobutamine echocardiography (2.5 up to 40 micrograms.kg-1.min-1) and rest-redistribution 201Tl tomography 1 day before revascularization [13].
• Finally, the prognostic impact of dipyridamole echocardiography on patients recovering from acute myocardial infarction was assessed in a consecutive series of 151 patients [14].
• BACKGROUND: Both thallium imaging and low-dose dobutamine echocardiography have been proposed to predict the reversibility of left ventricular (LV) dysfunction in patients with coronary disease [15].
• METHODS AND RESULTS: Patients with stable ischemic heart disease (n = 27) had positron emission tomographic measurement of blood flow at rest and with adenosine, and echocardiography at rest and with dobutamine [16].

Biological context of Echocardiography

• Left ventricular structure was determined by two-dimensional guided M-mode echocardiography, renal blood flow by iodine I 131 aminohippuric acid clearance, and glomerular filtration rate by creatinine clearance [17].
• Cardiac output was measured in months 1, 12, and 24 by echocardiography. r-hGH induced a fourfold increase in plasma IGF-1 concentrations within the first month of treatment [18].
• Left ventricular function was evaluated by echocardiography before (at rest and during low-dose dobutamine infusion) and 5 months after revascularization [19].
• Systolic time intervals, echocardiography, cardiac index and treadmill exercise tolerance were used to follow the progress of the control and dobutamine treatment groups [20].
• Efficacy of ambulatory systemic vasodilator therapy with oral prazosin in chronic refractory heart failure. Concomitant relief of pulmonary congestion and elevation of pump output demonstrated by improvements in symptomatology, exercise tolerance, hemodynamics and echocardiography [21].

Anatomical context of Echocardiography

• Letter: Echocardiography of mitral valve in rheumatoid arthritis [22].
• Of 965 patients with hypertrophic cardiomyopathy evaluated by echocardiography at the National Institutes of Health during a 7-year period, 23 (2%) had a nonobstructive morphologic form, in which wall thickening occurred predominantly in the apical (distal) portion of the left ventricle [23].
• Dipyridamole echocardiography. A new diagnostic window on coronary artery disease [24].
• In addition, the concordance between resting 201Tl imaging and dobutamine echocardiography in identifying viable myocardium has not been assessed [25].
• Thus, contrast echocardiography provided a method for identifying the site of pulmonary venous drainage and for distinguishing the common pulmonary vein from other structures such as the inferior vena cava [26].

Associations of Echocardiography with chemical compounds

• Dipyridamole stress can also be employed in association with echocardiography for detection of ischemia-induced regional wall motion abnormalities [27].
• More patients preferred dobutamine (48%) or dipyridamole (40%) echocardiography to adenosine echocardiography (12%; P less than 0.001) [28].
• CONCLUSION: On serial echocardiography, fenfluramine-associated valvular regurgitation improved or remained stable in most patients after therapy ended [29].
• INTERVENTIONS: Maximal exercise treadmill testing and exercise echocardiography were done at baseline, after acute ingestion of a placebo beverage (97% caffeine-free coffee), or after drinking an identical beverage containing 250 mg of caffeine sodium benzoate [30].
• These differences were exaggerated after nitroglycerin, while concomitant changes in relative wall thickness were virtually undetected by M mode echocardiography [31].

Gene context of Echocardiography

• MEK1 transgenic mice showed a dramatic increase in cardiac function, as measured by echocardiography and isolated working heart preparation, without signs of decompensation over time [32].
• Echocardiography performed at 3 weeks and 3 months revealed preservation of both left ventricular size and systolic function in banded MCIP1 mice despite the attenuated hypertrophic response [33].
• At four months of age, Cav-3 knock-out hearts display significant hypertrophy, dilation, and reduced fractional shortening, as revealed by gated cardiac MRI and transthoracic echocardiography [34].
• All subjects underwent screening for RyR2 mutations, electrocardiography (ECG), 24-h Holter monitoring, signal-averaged electrocardiography (SAECG), two-dimensional echocardiography and exercise stress testing [35].
• The character and extent of the heart failure that occurs in MLP(-/-) mice were investigated using echocardiography and in vivo pressure-volume (P-V) loop measurements [36].

Analytical, diagnostic and therapeutic context of Echocardiography

• The long-term cardiorespiratory effects of recombinant human erythropoietin treatment were investigated in ten haemodialysis patients by means of maximum exercise testing, lung function tests, echocardiography, chest X-ray, and rheological assessment over 12 months [37].
• Ten patients had at least one transient, cold-induced, myocardial perfusion defect visualized by thallium-201 scintigraphy, and 12 had reversible, cold-induced, segmental left ventricular hypokinesis by two-dimensional echocardiography [38].
• The overall sensitivity of dipyridamole echocardiography was similar to that of exercise ECG (75% versus 74%, P = NS), with no significant differences in the subset with one- (67% versus 69%, P = NS), two- (79% versus 77%, P = NS), or three- (93% versus 86%, P = NS) vessel disease [39].
