Death Risk Prediction in Patients with Heart Failure
- Conclusion
- Data Analysis
- Hypothesis
index
- Introduction
Development of indicator that can help to predict death risks by using the collected database.
Mainly focused on the relationship between ejection fraction and Heart failue.

Serum Biochemical Index
Potential and predictive value of Serum Biochemical Index in survival evaluation among patients with the diagnosis of heart failure
Hypothesis
Table 1. Meanings, measurement units, and intervals of each feature of the dataset
Davide Chicco and Giuseppe Jurman (2020), BMC Medical Informatics & Decision Making, 2/3/2020, Vol. 20 Issue 1, p1-16, 16p, 11 Charts, 4 Graphs, Chart; found on p3, https://doi.org/10.1186/s12911-020-1023-5
Data analysis
- Level of Creatinine Phosphokinase
- Level of Serum creatinine
- Level of Serum sodium
Numerical data
- Diagnosis of Diabetes
Boolean data
Figure 1. A Bar charts for categorical data consisting of death event with statistical details about the percentage of diagnostic of diabetes included in the plot of each bar.
Table 2. A two-way contingency table summarized the frequency distribution of death events during the followed-up period associated with the diagnosis of diabetes.
Boolean Data analysis
Table 3. Statistical analysis on numerical data with Mann-Whitney to test if a significant difference emerged.
Numerical Data analysis
- Small sample
- Limited followed-up period
- Possibly inaccurate recordings
- Great importance for research
- Great value for reference.
- Wider applied in the futrue
- Merely the level of serum creatinine and sodium in the blood shown significant difference in death events during followed peirod
- The level of serum creatinine and sodium are possible to be used as prognostication for predict death event in heart failure
- The level of CPK enzyme could not be a significant indicator.
- the diagnosis of diabetes could not serve as a diagnostic tool for mortality of heart failure
