[Selective survey of lifestyle habits within families].

Efforts to influence favourably the health status of our population lead to ever more detailed analyses of the life style and influence of the family on the habits of the young generation. The authors made two pilot studies. In the first one they focused attention on dietary habits and in the second one on the leisure time, incl. physical activity. The results should be applied not only in health education but also in food production and sale, and by the national committees with respect to supplies, the standard of services, transport etc.

Equilibrium radionuclide ventriculography in men after transmural myocardial infarction.

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.

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.

Regional pulmonary function in patients with mitral stenosis in relation to haemodynamic data.

Central haemodynamics in 23 patients with mitral stenosis and 7 control subjects were compared with the results of regional lung perfusion studied by (133)Xe, pulmonary scintigraphy with (99)mTc-labelled macro-aggregates of albumin, and regional ventilation by (133)Xe.A close correlation was found between both methods assessing regional pulmonary perfusion, i.e. pulmonary scintigraphy and (133)Xe. The results show that lower lung zones, when compared with upper zones, have both worse perfusion and worse ventilation. The changed distribution of perfusion and the changed distribution of ventilation correlated significantly with central haemodynamics in these patients. The ventilation gradient can be a valuable diagnostic tool for evaluating the severity of mitral stenosis, especially in long and repeated studies, due to its simplicity for the patient.
