Echocardiographic study of infarcted animals after 6 months of observation
| Variables | Without HF (n = 34) | With HF (n = 54) | p-value |
|---|---|---|---|
| LAD (mm) | 6.90 ± 1.29 | 8.16 ± 1.30 | < 0.001 |
| LVDD (mm) | 10.6 ± 0.84 | 11.4 ± 1.05 | < 0.001 |
| LVSD (mm) | 8.17 ± 1.13 | 9.02 ± 1.39 | 0.002 |
| LVMI | 3.14 (2.81-3.59) | 3.64 (2.78-4.50) | 0.018 |
| E/A | 1.43 (1.24-1.70) | 3.91 (1.35-6.27) | 0.002 |
| IVRT/HR (ms) | 73.9 ± 12.1 | 66.7 ± 12.0 | 0.008 |
| EDT (ms) | 43.1 ± 8.8 | 38.3 ± 10.2 | 0.036 |
| AVF (%) | 33.3 ± 8.6 | 29.6 ± 7.6 | 0.040 |
| PWSV | 25.9 (22.6-28.4) | 24.2 (20.6-28.3) | 0.344 |
Data are expressed as mean ± standard deviation (for normal distribution) or median with 25 and 75 percentiles (for non-normal distribution). HF: heart failure; LAD: left atrium diameter; LVDD: left ventricular diastolic diameter; LVSD: left ventricular systolic diameter; LVMI: left ventricular mass index; E/A: E/A wave ratio; IVRT/HR: isovolumic relaxation time adjusted by heart rate; EDT: E-wave deceleration time; AVF: area variation fraction; PWSV: posterior wall shortening velocity.
