Insights
The early systemic immune-inflammation (SII) index is higher in patients experiencing stroke-induced heart syndrome. This index independently predicts cardiac complications following acute ischemic stroke.
Area of Science:
- Cardiology
- Neurology
- Immunology
Background:
- Stroke-induced heart syndrome is a frequent and serious complication of ischemic stroke.
- It is associated with poor patient prognosis, necessitating further research into its mechanisms.
- Understanding these mechanisms is crucial for improving clinical decision-making.
Purpose of the Study:
- To investigate the association between the early systemic immune-inflammation (SII) index and cardiac complications after acute ischemic stroke.
- To determine if the SII index can predict the development of stroke-heart syndrome.
Main Methods:
- Prospective collection and retrospective analysis of acute ischemic stroke patients from January 2020 to August 2022.
- Inclusion criteria: presentation within 24 hours of symptom onset, absence of infection or cancer.
- Calculation of the SII index [(neutrophils × platelets/lymphocytes)/1000] from admission laboratory data.
Main Results:
- 121 patients were analyzed; 24 (19.8%) developed cardiac complications within 14 days.
- Patients with stroke-heart syndrome exhibited significantly higher SII levels (p<.001).
- The SII index was an independent predictor of stroke-heart syndrome (aOR 5.089, p=.002).
Conclusions:
- New-onset cardiovascular complications after stroke are common.
- The early systemic immune-inflammation (SII) index is strongly associated with these complications.
Background:
Stroke-induced heart syndrome is a feared complication of ischemic stroke, that is commonly encountered and has a strong association with unfavorable prognosis. More research is needed to explore underlying mechanisms and inform clinical decision making. This study aims to explore the relationship between the early systemic immune-inflammation (SII) index and the cardiac complications after acute ischemic stroke.
Methods:
Consecutive patients with acute ischemic stroke were prospectively collected from January 2020 to August 2022 and retrospectively analyzed. We included subjects who presented within 24 hours after symptom onset and were free of detectable infections or cancer on admission. SII index [(neutrophils × platelets/ lymphocytes)/1000] was calculated from laboratory data at admission.
Results:
A total of 121 patients were included in our study, of which 24 (19.8 %) developed cardiac complications within 14 days following acute ischemic stroke. The SII level was found higher in patients with stroke-heart syndrome (p<.001), which was an independent predictor of stroke-heart syndrome (adjusted odds ratio 5.089, p=.002).
Conclusion:
New-onset cardiovascular complications diagnosed following a stroke are very common and are associated with early SII index.
