Comparison of traditional BP variability metrics in salt‐sensitive and ‐protected rats
| Study group/Treatment | Salt sensitive | Salt protected | ||||
|---|---|---|---|---|---|---|
| Low salt | High salt | ΔHS‐LS | Low salt | High salt | ΔHS‐LS | |
| Systolic BP | ||||||
| SD (mmHg) | 4.40 ± 0.30 | 5.73 ± 0.46 | 1.33 ± 0.57 | 4.30 ± 1.30 | 5.19 ± 0.49 | 0.89 ± 0.59 |
| CV (%) | 3.2 ± 0.2 | 2.9 ± 0.2 | −0.30 ± 0.34 | 3.5 ± 0.4 | 3.4 ± 0.4 | −0.10 ± 0.48 |
| Diastolic BP | ||||||
| SD (mmHg) | 4.03 ± 0.31 | 4.70 ± 0.48 | 0.67 ± 0.59 | 3.80 ± 0.50 | 4.65 ± 0.56 | 0.85 ± 0.58 |
| CV (%) | 3.97 ± 0.25 | 3.13 ± 0.29 | 0.85 ± 0.41 | 3.89 ± 0.47 | 3.82 ± 0.47 | −0.08 ± 0.48 |
Number of beats: 626–953; data shown as mean ± standard error averaged across rats within a group; ΔHS‐LS: changes calculated as (high‐salt − low‐salt) values.
