简要总结
The objective of the present study is to asses the effectiveness of the aorta-ventricular coupling according to low and high sodium intake in 28 controled hypertensive patients.
详细描述
Comparison of left ventricular function in two groups of 13 patients according to their different salt's consumption in double blind and crossover study. Performance estimation of the left ventricle by echocardiographic and central arterial pressure by tonometry.
