Treadmill Test and Ambulatory Blood Pressure Monitoring: Can They Be Performed on the Same Day? Can the Effort Reached on the Treadmill Interfere?

TL;DR

Performing the exercise stress test and ABPM on the same day did not affect ABPM blood pressure values, and the intensity reached during the test, whether submaximal or maximal, did not influence ABPM results.

Key Findings

Performing an exercise stress test and ABPM on the same day did not affect maximum systolic blood pressure values during wakefulness or sleep.

  • 190 adults participated in the study total; same-day group n=145, different-day group n=45
  • Maximum systolic blood pressure during wakefulness: p=0.5307
  • Maximum systolic blood pressure during sleep: p=0.7383
  • All p-values were non-significant, indicating no meaningful difference between groups

Performing an exercise stress test and ABPM on the same day did not affect maximum or minimum diastolic blood pressure values during wakefulness or sleep.

  • Maximum diastolic pressure during wakefulness: p=0.2691
  • Maximum diastolic pressure during sleep: p=0.3974
  • Minimum diastolic pressure during wakefulness: p=0.1289
  • Minimum diastolic pressure during sleep: p=0.8075

Performing an exercise stress test and ABPM on the same day did not affect minimum systolic blood pressure values during wakefulness or sleep.

  • Minimum systolic pressure during wakefulness: p=0.4615
  • Minimum systolic pressure during sleep: p=0.5584
  • Comparisons were made between same-day (n=145) and different-day (n=45) groups

The intensity of effort reached during the exercise stress test (submaximal versus maximal heart rate) did not influence ABPM systolic blood pressure values.

  • Submaximal group n=95, maximal group n=50
  • Maximum systolic pressure during wakefulness: p=0.1029
  • Maximum systolic pressure during sleep: p=0.2149
  • Minimum systolic pressure during wakefulness: p=0.7964
  • Minimum systolic pressure during sleep: p=0.8991

The intensity of effort reached during the exercise stress test (submaximal versus maximal heart rate) did not influence ABPM diastolic blood pressure values.

  • Maximum diastolic pressure during wakefulness: p=0.2062
  • Maximum diastolic pressure during sleep: p=0.1851
  • Minimum diastolic pressure during wakefulness: p=0.8864
  • Minimum diastolic pressure during sleep: p=0.4892

What This Means

This research suggests that patients who need both a treadmill exercise stress test and a 24-hour ambulatory blood pressure monitor (ABPM) do not need to schedule these tests on separate days. The study followed 190 adults, comparing those who had both tests on the same day (145 people) versus on different days (45 people), and found no meaningful differences in any blood pressure measurements recorded by the ABPM — whether during waking hours or sleep. The study also examined whether pushing harder during the treadmill test (reaching a maximum versus submaximal heart rate) made any difference to subsequent ABPM readings. Again, no significant differences were found across all blood pressure measurements during either wakefulness or sleep, suggesting that even vigorous exercise on the treadmill does not distort the ABPM results. This research suggests that combining both tests into a single visit is clinically acceptable, which could have practical benefits for patients and healthcare systems by reducing the number of separate appointments needed. The findings may help simplify the diagnostic workup for patients being evaluated for cardiovascular conditions, saving time and potentially reducing costs.
