[Echocardiograhy in athletes].

The electrocardiogrammes and echocardiogrammes of 10 weight lifters and 20 endurance trained top class athletes (runners, basket ball players and cyclists) were analysed. The electrocardiogrammes confirmed the notion of a specific profile in endurance trained athletes with left ventricular diastolic overload pattern. The echocardiogrammes did not show increased left ventricular wall thickness in the resistance trained athletes. It did show however a clear increase in left ventricular internal diastolic dimension and posteror wall thickness--the anatomical substratum of the large heart in athletes--in some categories of endurance trained athletes (cyclists and basket ball players). No change in the indices of left ventricular performance was found in either group.

[Comparison of echocardiography and phonomecanography in adult aortic valve stenosis. 55 cases].

The results of echocardiography and phonomecanography were compared in 55 cases of adult valvular aortic stenosis. Although the most reliable echocardiographic sign of the severity of stenosis is the systolic separation of the aortic valve echos, it should be amphasised that: -- this cannot be measured in 25 % cases; --in 10 % cases the values obtained vary with the angle of the transducer. In these cases, the finding of a left ventricular posterior wall thickness greater than or equal to 15 mm is specific for severe aortic stenosis. On the other hand, the left atrial, left ventricular and aortic internal dimensions and the morphology of the mitral leaflets do not help in the estimation of the severity of adult aortic stenosis. The best correlations between echo and phonocardiography are the values of aortic valve opening and : --hemi-ascension time (r = 0.67); --left ventricular ejectiontime (r = 0.93) when patients in cardiac failure are excluded. The complementary nature of these two investigations is notable, and should, in pure aortic stenosis without angina, spare patients who are often elderly and fragile from heamodynamic investigation.

[Left ventricular function with effort in the coronary patient. Study of the correlations with the data on echocardiography, effort ECG, and the teleheart. 2].

Correlations were established, for 30 coronary patients, between the haemodynamic findings and those adduced from non-invasive techniques - electrocardiography, both at rest and on exercise, telethorax, and echocardiography. Left ventricular function in the coronary patient can be assessed, even before catheterisation, by means of: 1. The clinical findings: angina of effort, an uncomplicated infarct, and an infarct with sequelae each has its own peculiar haemodynamic pattern at rest and on exercise; 2. The ECG finding of an extensive anterior infarct implies a haemodynamic picture vastly different from that with a limited posterior infarction; 3. The appearance of an ischaemic shift in the ST segment on exercise implies an acute malfunctioning of the left ventricle; 4. On the echocardiogram, an end-diastolic volume greater than 150 ml/m2, an ejection fraction less than 0.50 and VCF greater than 0.8 c/s are always accompanied by disturbances in the haemodynamics. By contrast, the cardio-thoracic ratio, except in post-infarct cases complicated by left ventricular failure, gives no predictive indication of cardiac function. These various examinations should therefore be applied to the coronary patient as an index of cardiac function.

[Value of calcium inhibitors in stable effort angina. Diltiazem versus nifedipine].

Few studies have been devoted to the role of calcium blockers in stable angina of effort. For this reason, we undertook, a double-blind, randomized study with placebo, to compare the effects of diltiazem (D) and nifedipine (N) on the ergometric parameters of 20 patients with angina of effort and with mono- or multivessel disease. The study protocol extended over 3 weeks and included a reference stress test, 8 days of placebo followed by a repeat yesy, an then 15 days during which each patient received 180 mg of D and/or 30 mg of N in cross-over. A stress test was performed at the end of each week. The calcium blockers appeared to improve the effort tolerance, the duration of the ergometric test and the amplitude of the maximal ST segment depression. Diltiazem showed itself to be superior to nifedipine by the absence of side effects and by an improved cardiac performance on effort.
