| pubmed-article:6709925 | pubmed:abstractText | Right and left atrial function were assessed using Fourier analysis of gated radionuclide images in 14 normal subjects and 50 patients with long-standing essential hypertension. Slopes representing filling and early diastolic emptying were similar for both atria; however, early diastolic emptying of the left atrium was slowed markedly in the hypertensive group (42.6 +/- 18.6 counts/sec., vs. 79 +/- 16 in normal persons; p less than 0.001), implying a reduction in left ventricular compliance. The right ventricular ejection fraction was depressed in hypertensive patients compared with normal subjects (37.1 +/- 6% vs. 43.4 +/- 8.1%; p less than 0.01). These findings may be helpful in understanding the effect of hypertension on the left and right heart and could have prognostic and therapeutic implications as well. | lld:pubmed |
