Objective:
To assess the associations between domain-specific physical activity (occupation-related physical activity; transportation-related physical activity; leisure-time physical activity) and sedentary behavior and mortality among participants with chest pain.
Design:
Cohort observational studies examined the associations between domain-specific physical activity and sedentary behaviors with mortality among participants with chest pain, adjusting for age, sex, race, and other medical comorbidities among chest pain adults (the National Health and Nutrition Examination Survey).
Setting:
Community setting.
Participants:
Participants aged 40 to 80 years were asked by well-trained staff whether they had ever felt pain or discomfort in their chest (N=23,226). If the answer was yes, they were diagnosed with chest pain. This study included 4412 participants with complete data who had chest pain; their average age was 57.99 ± 0.26 years, and 51.90% (2283) of them were women.
Interventions:
Not applicable.
Main Outcome Measures:
Domain-specific physical activity and sedentary behaviors were assessed by using the Global Physical Activity Questionnaire, categorizing participants by the 2018 Physical Activity Guidelines and daily sitting time. Mortality outcomes (all-cause and cardiovascular) were determined via National Death Index records linked to ICD-10 codes up to December 2019.
Results:
Among chest pain participants, higher levels of total or domain-specific physical activity were associated with reduced all-cause and cardiovascular-related mortality risks. Conversely, sitting time exceeding 480 minutes daily significantly increased these risks. Regular leisure-time physical activity mitigated mortality risks, even with the mortality risk associated with sedentary behaviors.
Conclusions:
In adults with chest pain, regular leisure-time physical activity proved more effective than weekend warrior patterns in reducing mortality risks and mitigating the mortality risk token with sedentary behaviors.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
