Thus, post-MI LV remodeling is an arrhythmic complication and it is associated with post-MI heart failure and the long-term prognosis of MI 2, 3.Īnalysis of variations in heart rate oscillation, also known as heart rate variability (HRV), is commonly used to assess the autonomic nervous system due to its simple and noninvasive approach 4. After the acute phase of myocardial infarction (MI), neurohormonal and mechanical stimuli lead to progressive left ventricular (LV) remodeling 1.

In conclusion, the patients with STEMI had serial changes in cardiac complexity.Īcute myocardial infarction (AMI) is one of the leading causes of mortality and morbidity worldwide. In both the net reclassification improvement and integrated discrimination improvement models, MSE parameters significantly improved the discriminatory power of the linear parameters to differentiate the post-MI patients from the controls. Area 6–20 had the greatest discriminatory power to differentiate the post-MI patients (at 1 year) from the controls. The areas under the MSE curves for scale 1 to 5 (area 1–5) and 6 to 20 (area 6–20) were lower throughout the chronic stage. In multiscale entropy (MSE) analysis, the patients had a lower slope 5 in the acute stage, which then gradually increased during the follow-up period. In detrended fluctuation analysis (DFA), the patients had significantly lower DFAα2 in the acute stage (within 72 hours) and lower DFAα1 at 3 months and 12 months after MI. We prospectively enrolled 27 patients with anterior wall ST segment elevation myocardial infarction (STEMI) and 42 control subjects. The aim of this study was to analyze serial changes in heart rhythm complexity from the acute to chronic phase of acute myocardial infarction (MI). Heart rhythm complexity analysis has been shown to have good prognostic power in patients with cardiovascular disease.
