Table 4 Strain rate and strain analysis of left ventricular lateral free wall and interventricular septal wall.
| Segment | SR (1/s) | Strain (%) | ||||

| Controls (n = 25) | Users (n = 20) | Non‐users (n = 25) | Controls | Users | Non‐users | |
| Left ventricular lateral free wall | ||||||
| Basal | −1.8 (0.4) | −1.6 (−0.3)* | −2 (0.4) | −19 (6) | −15 (5)* | −20 (6) |
| Middle | −1.8 (0.2) | −1.1 (0.3)* | −1.9 (0.2) | −24 (4) | −16 (4)* | −26 (4) |
