Deans' stroke musings: Impact of sedentary behavior and physical activity on stroke risk in a cohort of patients with silent brain infarction

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Impact of sedentary behavior and physical activity on stroke risk in a cohort of patients with silent brain infarction

If it is silent, how the hell are you supposed to know to reduce your sedentary time. Described a problem, offered NO solution; USELESS!

Abstract

Silent brain infarction (SBI) is associated with a markedly increased risk of subsequent stroke. Identifying actionable, modifiable risk factors for stroke prevention is essential. Physical activity (PA) is a known protective factor, but the specific impact of sedentary behavior on stroke risk in SBI patients and its interaction with PA remain unclear. This study examines the independent and joint effects of sedentary time (ST) and PA on stroke risk in SBI patients. In this prospective cohort study, we used health check-up data from Chinese hospitals for SBI patients and followed participants for incident stroke. ST and PA were assessed at baseline. The dose–response relationship between ST and stroke risk was evaluated with restricted cubic spline regression. Cox proportional hazards models estimated the independent effects of ST, Moderate-to Vigorous Intensity Physical Activity (MVPA), and their joint effects on stroke risk. Compared with ST < 8 h/day, ST ≥ 8 h/day was associated with a substantially higher risk of stroke (HR, 4.20 [95% CI, 2.23–7.93]); For joint effects, compared with the reference group (ST < 8 h/day & MVPA ≥ 300 min per week (min/wk)), the group with ST ≥ 8 h/day and MVPA ≥ 300 min/week had (HR 3.32 [95% CI 1.11–9.89]). Prolonged sedentary time (≥ 8 h/day) is an independent risk factor for stroke in SBI patients. Engaging in ≥ 300 min/week of MVPA attenuates the adverse association between ST and stroke risk. Reducing sedentary behavior and achieving adequate MVPA may be important for stroke risk management in SBI patients.

Data availability

The datasets generated and/or analyzed during the current study are not publicly available due to the fact that they contain sensitive information that could compromise the privacy of participants. Additionally, the datasets are part of ongoing research projects, and sharing them publicly could interfere with future analyses.
