Insights
The SYNTAX Score II (SS II) predicts mortality in multivessel coronary artery disease (CAD). Higher SS II scores correlate with diabetes and hyperuricemia, but surprisingly also with high HDL and low LDL levels.
Area of Science:
- Cardiology
- Clinical Risk Assessment
Background:
- The SYNTAX Score II (SS II) is a validated tool for predicting mortality in patients with multivessel coronary artery disease (CAD).
- Understanding factors influencing SS II is crucial for optimizing treatment strategies, including percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG).
Purpose of the Study:
- To investigate the correlation between lipid profiles (HDL, LDL, total cholesterol, triglycerides), uric acid levels, and diabetes status with SS II values in CAD patients.
- To determine if traditional atherosclerosis risk factors are associated with higher SS II scores.
Main Methods:
- A cohort of 72 CAD patients was analyzed.
- SS II was calculated using an online calculator.
- Statistical analyses, including Mann Whitney U and Shapiro-Wilk tests, were employed to assess correlations between clinical parameters and SS II.
Main Results:
- A significant positive correlation was observed between high HDL levels and SS II for PCI.
- Lower LDL levels were associated with increased SS II for CABG.
- Hyperuricemia and diabetes status showed a significant positive correlation with SS II for PCI.
- No significant correlation was found for total cholesterol and triglycerides with either SS II PCI or SS II CABG.
Conclusions:
- SS II is associated with established atherosclerosis risk factors like diabetes and hyperuricemia.
- Unexpectedly, the study found correlations between SS II and lipid profiles, specifically high HDL and low LDL levels in this patient cohort.
- These findings suggest a complex interplay of factors influencing SS II and highlight the need for further research.
Abstract:
The SYNTAX Score II (SS II) is a clinical tool that allows individualized prediction of mortality in patients with multivessel coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The aim was to examine whether lipid profile, uric acid and diabetes had a positive correlation with higher values of SS II. The study included 72 CAD patients. An online calculator was used to calculate SS II. Statistical tests (Mann Whitney U test and Shapiro-Wilk test) were used to assess correlations and differences in lipid profile, uric acid and diabetes status according to SS II values. There was a significant positive correlation between the proportion of patients with HDL levels above the reference values and SS II PCI. Patients with lower LDL values had significantly increased values of SS II CABG, but not SS II PCI. There was no significant correlation of total cholesterol and triglycerides with SS II PCI or SS II CABG. Patients with hyperuricemia had significantly higher SS II PCI but not SS II CABG. People with diabetes had significantly increased SS II PCI but not SS II CABG compared to non-diabetic patients. In conclusion, SS II is associated with some of the classic risk factors for atherosclerosis (uric acid, diabetes), whereas in our patient cohort there was a surprising correlation of SS II with high HDL levels and low LDL levels.
