Regression coefficients with corresponding probability values for regression analyses between changes in echocardiographic variables plotted against baseline heart rate or heart rate reduction
Sinus rhythm (n=212) | Atrial fibrillation (n=45) | |||
Echocardiographic variable | IRI | p Value | IRI | p Value |
Baseline heart rate | ||||
Change in LVEDD | 0.156 | 0.03 | 0.198 | 0.22 |
Change in LVESD | 0.051 | 0.48 | 0.032 | 0.84 |
Change in LVFS | 0.096 | 0.19 | 0.254 | 0.12 |
Heart rate reduction | ||||
Change in LVEDD | 0.062 | 0.42 | 0.041 | 0.81 |
Change in LVESD | 0.093 | 0.23 | 0.152 | 0.37 |
Change in LVFS | 0.056 | 0.46 | 0.258 | 0.12 |
Applying a Bonferroni correction, a p value of < 0.004 was considered significant.
IRI, regression coefficient; LVEDD, left ventricular end diastolic dimension; LVESD, left ventricular end systolic dimension; LVFS, left ventricular fractional shortening.
