Echocardiographic Doppler evaluation of left ventricular diastolic function in athletes' hypertrophied hearts.

It is well known that one of the most evident effects of prolonged and intense physical training is an increase of left ventricular mass. This increase could have a great influence on the diastolic properties of the heart, which can now be accurately evaluated by use of pulsed- and continuous-wave of Doppler echocardiography. The aim of this study was to evaluate the diastolic function of a group of superendurance athletes (professional bicyclists, exercising more than forty hours a week). Sixteen athletes (A), aged between twenty and thirty-one years, during the period of maximal training, and 16 age-matched controls (C) were studied. All subjects were evaluated at rest with mono-dimensional, two-dimensional, and Doppler echocardiography. Diastolic (DD) and systolic (SD) diameter, posterior wall (PW), and interventricular septum (IVS) thickness were also measured. The left ventricular mass (LVM) was calculated. Diastolic function was evaluated by calculating isovolumetric relaxation time (IVR) with continuous-wave Doppler, and deceleration time (DT), rapid filling flow peak (Ep), and atrial filling peak (Ap) were evaluated with pulsed Doppler echocardiography. The LVM (A: 354 +/- 47 g vs C: 170.6 +/- 33.4, p < 0.05), DD (A: 57.7 +/- 3.9 mm vs C: 50.5 +/- 2.7, p < 0.01), PW thickness (A: 11.9 +/- 0.7 mm vs C: 8.4 +/- 0.6, p < 0.05), and IVS thickness (A: 12.3 +/- 1 mm vs C: 8.2 +/- 0.9, p < 0.05) were significantly greater in the athletes than in the controls.(ABSTRACT TRUNCATED AT 250 WORDS)

[The diameter of the common trunk of the left coronary artery and left ventricular mass in athletes. An echocardiographic study].

The feasibility of two-dimensional echocardiographic visualization of the coronary artery was re-evaluated in adults in the light of technological advances and development of new imaging planes. Athletes are a good model for this type of study. The aim of our study was to visualize in athletes the coronary arteries, particularly the left main artery, and to see if a correlation exists between left-ventricular mass and coronary diameter. Twenty-one endurance athletes, aged between 17 and 30 years, and 21 control subjects, matched for age, sex and body surface area, were examined. All the subjects were examined with mono- and two-dimensional echocardiography, with annular array (3.5 and 5 MHz), with parasternal and apical projections modified in order to visualize the left main coronary artery. Wall thickness, left ventricular internal dimension and left ventricular mass were calculated. Interventricular septum thickness was 10.8 +/- 1.5 mm for athletes (A) versus 8.2 +/- 0.9 mm for controls (C); p less than 0.01. Posterior wall thickness was 10.4 +/- 1.5 mm (A) versus 8.2 +/- 0.6 mm (C); p less than 0.01. The left ventricular diastolic diameter was 54.6 +/- 5.1 mm (A) versus 49.5 +/- 3.4 mm (C); p less than 0.01. The mean left ventricular mass was 278.2 +/- 85.2 g (A) versus 165.6 +/- 35.4 g (C); p less than 0.01. The mean diameter of the left main coronary artery was 4.9 +/- 0.8 mm (A) versus 3.1 +/- 0.4 mm (C); p less than 0.01.(ABSTRACT TRUNCATED AT 250 WORDS)

[In vivo densitometry of the skeleton by single energy CT body scanner for clinical use. Technical procedure. Cross-sectional study of 124 subjects on the role of age and sex. Evaluation of the cortical/spongiosa ratio as a function of age].

CT 5005 EMI Scanner 140 kVp. Abstraction of the HN in the cortical of the right femural diaphysis and in the spongiosa of the vertebral body (L1). 124 clinically normal subjects of both sexes (63 males and 61 females), aged between 20 and 87 years were grouped into 7 categories according to age decade. Cortical-male - The variations of bone mineral content are not correlated either with age or with sex. Cortical-female - Modest correlation with age but not calculable with sex. Spongiosa-male - Excellent correlation with age (r = --0,975; (p less than 0,005). In each decade the average male values are superior to the female values. Spongiosa-female - Excellent linear correlation with age (r = --0,945; p less than 0,005). The average values for each decade are inferior to those of the males. The cortical/spongiosa ratio increases in relation to age: in males (r = --0,896; p less than 0,01) and in females (r = --0,885; p less than 0,01). The bone mineral content loss in the IX decade compared to the III decade is equal in males and in females in both the cortical (--20%) and the spongiosa (--65%). The reduction curves with the CT body scanner are not comparable to those obtained with other techniques. They result as being compatible with those obtained through histomorphometry (trabecular bone density).
