Emission computer tomoventriculography.

The method of equilibrium radionuclide ventriculography relies on ECG synchronized scintigraphic data acquisition. In addition, the authors used respiratory phase synchronization. Combining the equilibrium radionuclide ventriculography with emission computer tomography (ECT), they obtained transverse heart images in different phases of the cardiac cycle. Through addition of the third dimension the images enhance the quality of studies of the heart.

Equilibrium radionuclide ventriculography in men after transmural myocardial infarction.

PubMed (1983)

A Nestával Stanĕk I. Málek J Kidéry I Runczik

Using equilibrium radionuclide ventriculography, the authors investigated left ventricular ejection fraction in 10 healthy men and in 57 men who had undergone their first transmural myocardial infarction (MI) 4 to 7 months earlier, were below 65 years of age and did not present signs of heart failure at the time of examination. Resting ejection fraction in healthy men amounted to 63 +/- 5%, in patients with uncomplicated MI to 54 +/- 7%, and in patients with clinical manifestations of heart failure in the acute phase to 37 +/- 8%. Patients with anteroseptal MI showed a negative correlation between the ejection fraction, on the one hand, and the sum of Q wave voltages in the precordial ECG map and the maximum value of serum creatine kinase in the acute phase of MI, on the other hand. The ejection fraction correlated with the degree of pulmonary hypertension during exercise. At work load of 50 W the ejection fraction measured in 31 patients was not significantly different shortly before discharge from hospital and 6 months after the onset of MI.

Equilibrium radionuclide right ventriculography at rest and during exercise in patients with pulmonary hypertension.

PubMed (1986)

A Nestával J Kidéry P Frídl A Oppelt J Widimský

Using the method of equilibrium radionuclide ventriculography (RNV), the right ventricular ejection fraction (RVEF) at rest and at a standard workload of 250 kpm per min was determined in 25 control subjects and in 30 patients with pulmonary hypertension (8 patients with chronic obstructive bronchopulmonary disease, 12 with recurrent pulmonary embolism and 10 with pure mitral stenosis). In the same week as RNV, pulmonary artery pressure was registered in patients with pulmonary hypertension at rest and at standard workload. RVEF was significantly higher (45 +/- 5%) in normal subjects than in patients with pulmonary hypertension (33 +/- 5%) and during exercise increased, whereas in patients with pulmonary hypertension it did not markedly change or decreased. The RVEF correlated at rest (r = -0.6293, p less than 0.001) and during exercise (r = 0.6980, p less than 0.05) with the degree of pulmonary hypertension at rest and during exercise. The results show a good correlation between the RVEF and the degree of pulmonary hypertension in patients with pulmonary hypertension at rest and during exercise.

[The importance of 201Tl scintigraphy in stress tests for the diagnosis of silent myocardial ischemia].

PubMed (1990)

J Kasalický J Kidéry J Svačinka J Vanko J Brunová

Using thallium scintigraphy after a load (LTS), the authors tested suspected silent myocardial ischaemia (SIM) in subjects without angina pectoris. They examined 21 active pilots suspected of SIM after a previous ECG loading test (LET) and 33 patients with diabetes type I and II. In six pilots (28.6%) they found on LTS accumulation defects suggesting ischaemic disorders of the large coronary arteries. All except one had during submaximal load during LTS obvious depression of the ST segment on the ECG. Except one, in another five pilots small depressions of the ST segment were associated with normal LTS. Twelve diabetic patients (36.4%) had obvious minor accumulation defects on LTS. Only two had on the ECG a ST depression under 2 mm during LTS. Based on data in the literature suggesting a higher sensitivity and specificity of LTS, as compared with LET and the possibility of a false positive diagnosis of SIM from LET alone, the authors recommend when SIM is suspected to use also LTS. A more detailed diagnosis of SIM is essential not only with regard to the assessment of work capacity but also for the long-term follow-up of patients with SIM for assessment of its incidence, impact and prognosis in our population.
