Insights
Patients with a history of cardiovascular surgery do not show a greater likelihood of recognizing stroke or calling emergency medical services (EMS). Counseling on stroke recognition and risk factor control is recommended for these patients.
Area of Science:
- Neurology
- Cardiology
- Public Health
Background:
- Patients with a history of cardiovascular surgery face increased stroke risk.
- Prompt emergency medical services (EMS) activation is critical for effective stroke reperfusion therapy.
Purpose of the Study:
- To investigate the impact of a cardiovascular surgical history on stroke recognition and the intent to call EMS.
- To analyze the association between cardiovascular surgery history and timely stroke response.
Main Methods:
- Cross-sectional community-based study in China (January-May 2017).
- Analysis of 186,167 individuals across 69 administrative areas.
- Multivariable logistic regression models to assess associations between cardiovascular surgical history and stroke recognition or EMS intent.
Main Results:
- 0.1% of the population had a cardiovascular surgery history.
- Stroke recognition rate was 84.9% and correct action rate was 74.7% in the surgery group.
- Cardiovascular surgical history did not significantly impact stroke recognition or the likelihood of calling EMS after full adjustment.
Conclusions:
- A history of cardiovascular surgery does not appear to influence patients' propensity to call EMS promptly during a stroke.
- Enhanced patient education on stroke symptom recognition and risk factor management is crucial for individuals with a history of cardiovascular surgery.
Objectives:
Patients with a history of cardiovascular surgery are at risk of stroke, and immediately calling emergency medical services (EMS) after stroke onset is crucial to receiving effective reperfusion therapy. We aimed to determine the effect of a history of cardiovascular surgery on patients' ability to recognize stroke and intent to call EMS.
Methods:
We performed a cross-sectional community-based study from January 2017 to May 2017. A total population of 186,167 individuals, recruited from 69 administrative areas across China, was analyzed. Different multivariable logistic regression models were performed to identify the associations between cardiovascular surgical history and stroke recognition or intent to call EMS, respectively.
Results:
0.1% of the total population had a history of cardiovascular surgery. In the surgery group, the estimated stroke recognition rate (SRR) and correct action rate (CAR) were 84.9% and 74.7%, respectively. The prevalence of cardiovascular risk factors was significantly higher in the surgery group. Cardiovascular surgical history was not associated with recognition of stroke across different models. The surgery group was more likely to call EMS, but the difference was not significant after full adjustment (OR: 1.40, 95% CI: 0.99-1.98, p = .0572).
Conclusions:
Cardiovascular surgical history does not influence patients' likelihood of calling EMS more often at stroke onset. Patients receiving cardiovascular surgeries should be counseled regarding stroke recognition, proper response to stroke, and the importance of controlling risk factors.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
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...
