Table 4. Demographic and clinical description of the patient population.
| SR group (n = 11) | AF group (n = 7) | p | |
|---|---|---|---|
| Age (years) | 67 ± 12 | 76 ± 4 | ns |
| Men, n (%) | 11 (100) | 7 (100) | ns |
| Aortic valve disease, n (%) | 7 (64) | 5 (71) | ns |
| Mitral valve disease, n (%) | 1 (9) | 3 (43) | ns |
| Coronary artery disease, n (%) | 3 (27) | 1 (14) | ns |
| Angina pectoris, n (%) | 6 (55) | 2 (29) | ns |
| Chronic obstructive pulmonary disease, n (%) | 1 (9) | 1 (14) | ns |
| Diabetes Mellitus, n (%) | 2 (18) | 1 (14) | ns |
| Hypertension, n (%) | 7 (64) | 7 (100) | ns |
| Renal insufficiency, n (%) | 1 (9) | 1 (14) | ns |
| Metabolic disease, n (%) | 3 (27) | 3 (43) | ns |
| Dilated left atrium (diameter ≥ 41 mm), n (%) | 7 (64) | 4 (57) | ns |
| LV EF, % | 64.5 [62–68] | 60 [53.5–68.5] | ns |
| Isolated AVR, n (%) | 3 (27) | 2 (29) | ns |
| Isolated MVR, n (%) | 0 (0) | 2 (29) | ns |
| Combined AVR and CABG, n (%) | 6 (55) | 3 (43) | ns |
| Combined MVR and CABG, n (%) | 2 (18) | 0 (0) | ns |
The two patient subgroups correspond to patients in sinus rhythm (SR) or atrial fibrillation (AF). Data are numbers (n) or percentages (%), and mean ± standard deviation or median [interquartile range], as pertinent. AVR, aortic valve replacement; CABG, coronary artery bypass grafting; LV EF, left ventricular ejection fraction; MVR, mitral valve replacement; ns, non-significant.
