| Outline of Final Research Achievements |
We aimed to evaluate temporal changes in cardiac autonomic nervous activity of cardiovascular surgery patients. Consecutive 50 patients who underwent cardiovascular surgery for valvular, ischemic heart and aortic diseases were enrolled. Electrocardiography was recorded for 15 min at supine position preoperatively and on the third, seventh, and fourteenth postoperative days to evaluate autonomic nervous activity by using spectral analysis of heart rate variability. Nine of 50 patients were excluded from further analysis. The autonomic nervous activity, defined as the total power, has been suppressed throughout postoperative days compared to that on the preoperative day. Especially, the high frequency power, an index of cardiac parasympathetic nerve activity, markedly decreased all postoperative days, and it did not recover to the preoperative level. The impaired autonomic nervous activity may continue immediately after cardiovascular surgery until the fourteenth postoperative day.
