Abstract
ObjectiveTo observe the changes of pulse wave after exercise and to explore the effect of a single individualized precise constant power exercise on pulse wave in patients with new‐onset chronic disease.Methods13 patients with new‐onset chronic disease, 16 normal persons and 16 patients with long‐term chronic disease were selected, all subjects were tested for symptom‐limited maximal cardiopulmonary exercise test (CPET), and individualized exercise prescriptions were formulated based on Δ50% power. First, the 50s pulse wave data in the resting state was measured and recorded. The subjects exercised for 30 minutes according to the established exercise intensity, and then measured and recorded the pulse wave data at 10, 20, and 30 minutes after the exercise, next analyzed and compared the pulse wave changes between patients and normal people.Results10min after exercise in newly‐onset chronic patients, YPL (the amplitude of the trough of a pulse wave notch), ΔPL (the amplitude difference between the trough of a pulse wave notch and the starting point of a pulse wave), TPL (the time of trough of a pulse wave notch), TE (time at the end of the pulse wave), and TE‐TPL (the duration of a pulse wave notch) were all reduced, while ΔTP2′(TP2‐TPL, the duration of trough to peak of a pulse wave notch) and notched pulse wave ratio increased. In other words, the pulse wave notch was more obvious, and the duration of a single pulse wave was shortened. This trend was maintained at 20min and 30min after exercise, but the duration of a single pulse wave increased with time. After exercise, the occurrence rate and apparent degree of the pulse wave notch in new‐onset chronic disease patients are not as good as those of normal people, but they are better than those of long‐term chronic disease patients.ConclusionA single individualized precise constant power exercise makes the pulse wave of patients with new‐onset chronic disease tend to be normal, but it is still worse than that of normal people, which prompts us to further explore the impact of long‐term exercise strengthening control on the pulse wave of patients with new‐onset chronic disease.
