Hypothesis
The study aims to evaluate the effect of shock index and its derivatives on acute heart failure clinical outcomes.
Conclusion
Shock index, age shock index, and modified shock index are practical tools for assessing prognosis in acute heart failure patients.
Supporting Evidence
- Mean shock index in those records reported mortality was 0.67.
- In-hospital mortality rate was 6.18% among 12955 patients.
- Deceased patients had higher shock index values compared to survivors.
- Shock index was associated with higher odds of in-hospital death (OR: 1.93).
- Optimal shock index cut-off point was found to be 0.79.
Takeaway
Doctors can use simple calculations like the shock index to help figure out how serious a heart failure patient is and how likely they are to get better.
Methodology
The study conducted a systematic review and meta-analysis of relevant records from PubMed/Medline, Scopus, and Web of Science databases.
Potential Biases
Potential biases in data collection and analysis due to the retrospective nature of most studies.
Limitations
Considerable heterogeneity among studies and potential biases due to retrospective designs.
Participant Demographics
Mean age of participants was 69.44 years, with a majority being male.
