[The role of the exercise test in patients with ischemic heart disease in estimating the risk of sudden death].

The authors evaluated after 4-year interval the results of coronarographic and spiroergometric examination after a work load on a bicycle ergometer up to the limiting work syndrome in 51 all patients with the aim to reveal "risk factors" of sudden death in CHD patients. The following parameters were recorded: age, duration of treatment number of cigarettes smoked, systolic blood pressure at rest and the daily dose of the most frequently used drugs. After the work load the limiting values of pulse rate, systolic blood pressure, oxygen consumption, blood lactate level and the work ECG were evaluated. In the group of 7 sudden deaths of CHD patients the authors found statistically significant (p less than 0.001) a lower mean limiting value of oxygen consumption/kg and a deeper (p less than 0.0001) mean depression of the S-T segment in the work ECG when compared with 35 CHD patients surviving for 4 years. Both indicators are considered the main "risk factors" for sudden death.

The development of symptomatology and functional condition in patients with negative or minimal findings on coronary vessels after 5 to 10 years.

The authors compared two groups of men: the group with minimal sclerotic wall changes (n = 18) and the group with a normal coronary angiographic finding (n = 32). All the examinations were repeated after 5 to 10 years (mean 8.4 years). The two groups did not differ in the occurrence of the main IHD risk factors, complaints, kind and amount of principal drugs and working history. No statistically significant differences were found between the groups in the reasons for discontinuing bicycle ergometric test or in the exercise ECG finding. The two groups studied did not differ in the mean values of limiting metabolic and cardiologic parameters (oxygen consumption, lactate, pulse rate, RPP index) either. The conclusion can be made that in the functional and clinical prognosis the group of symptomatic men with minor sclerotic wall changes does not differ practically from individuals with completely normal coronary angiography.

Possibilities and limitations of non-invasive techniques for the study of left ventricular function in chronic pulmonary disease.

The authors examined systolic time intervals, apexcardiograms and left ventricular echocardiograms in 151 patients with chronic disease of the airways. Their study showed that unlike apexcardiograms and echocardiograms, which can be performed in 33.8% and 56.7% of patients respectively, systolic time intervals can be assessed in 90.1% of patients. Pathological values of left ventricular function parameters were a comparatively common finding: 49.2% in systolic time intervals, 35.1% in apexcardiograms and 23.5 % in echocardiograms. There was no relation between the parameters of pulmonary function and those of left ventricular function. The authors hold that non-invasive examination of the left ventricular function in pulmonary disease is most valuable in long-term follow-up studies of the changes of the above parameters.

[Evaluation of left ventricular function in ischemic heart disease by systolic phase structure and echocardiographic indices].

The article describes poly- and echocardiographic examination of the ejection fraction, the mean contraction rate of the perimetric fiber of the left ventricle, the total tension period, the period of left ventricular ejection, and the tension period to ejection period ratio. The results obtained in a group of 17 healthy individuals were compared with the findings in patients with angina pectoris who were divided into 2 groups, one without any serious changes in the coronarogram (19) and the other with pathological changes in the coronary arteries (18). In patients with an abnormal coronarogram, the ejection fraction, the rate of contraction of the perimetric fiber, and the ejection period were considerably reduced. These values showed no significant changes in patients with a normal coronarogram. The ECG data correlated well with the systolic phase structure.
