Feasibility of simultaneous Tc99m sestamibi and 2D-echo cardiac imaging during dobutamine pharmacologic stress. Preliminary results in a female population.

Feasibility of simultaneous 2D-Echo and SPECT Tc99m Sestamibi imaging during dobutamine infusion was evaluated in a female population with suspected coronary artery disease and scheduled for diagnostic coronary angiography. A total of 49 consecutive subjects were studied. Patients under continuous ECG and 2D-Echo monitoring underwent standard dobutamine infusion at increasing doses to a diagnostic end-point.

[Standardization of the methods of lipid determination according to WHO in the regional project of prevention of cardiovascular diseases in Friuli-Venezia Giulia].

Background: The recognition of dyslipidemias as a major modifiable risk factor for atherosclerosis and coronary heart disease underlines the need to obtain precise and accurate assay results of plasma lipids. Today the use of automatic laboratory methods and of internal quality control favours the precision of the results but does not guarantee accuracy. The efficiency of a laboratory can be ensured by a standardization programme, systematically monitoring precision and accuracy by means of independent internal and external quality control, international reference standards (e.

Longitudinal evaluation of prostate-specific antigen levels in a case-control study.

Background: Over the last period--late 1970 to early 1990--the incidence of prostate carcinoma has nearly doubled, even though many more patients die with prostate cancer rather than of it. This finding, together with the slow growth of this tumor and the absence of a controlled trial, makes early diagnosis for this pathology quite questionable. On the other hand, it is well known that prostatic carcinoma is curable as long as it is intracapsular and that there is an ever increasing encouragement for early detection in all diseases.

Signal-averaged electrocardiography and Doppler echocardiographic study in predicting acute rejection in heart transplantation.

Background And Methods: In a prospective protocol for noninvasive diagnosis of acute cardiac rejection, 83 routine endomyocardial biopsies, followed each time by the analysis of signal-averaged electrocardiography and by a cardiac Doppler echocardiographic study, were performed in 18 heart transplant recipients. The follow-up time was 5 +/- 3.6 months.
