Objective:
To examine the association between changes in physical activity before and after a diagnosis of depression and risks of cardiovascular diseases (CVDs) and all-cause mortality.
Method:
A total of 1,282,160 patients with depression were included in the analyses. Subjects were divided into four groups (never, beginning, maintenance, and discontinuation) according to changes in physical activity before and after the diagnosis of depression. The occurrence of CVD including myocardial infarction (MI) and ischemic stroke and all-cause mortality were determined.
Results:
The beginning group showed decreased risks of MI (adjusted hazard ratio [aHR]: 0.85; 95% confidence interval [CI]: 0.81-0.89), ischemic stroke (aHR: 0.89; 95% CI: 0.85-0.93), and all-cause mortality (aHR: 0.80; 95% CI: 0.77-0.82) than the never group. Compared to the maintenance group, the discontinuation group showed increased risks of MI (aHR: 1.15; 95% CI: 1.08-1.23), ischemic stroke (aHR: 1.13; 95% CI: 1.06-1.21), and all-cause mortality (aHR: 1.29; 95% CI: 1.23-1.35).
Conclusions:
Beginning regular physical activity after a diagnosis of depression was associated with a decreased cardiovascular risk. Discontinuing regular physical activity after a diagnosis of depression was associated with an increased cardiovascular risk.

Exercise 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...
