Insights
The triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio is linked to higher in-hospital mortality in patients with acute type A aortic dissection (AAAD). This lipid ratio may serve as a valuable prognostic marker for AAAD patients.
Area of Science:
- Cardiovascular Medicine
- Lipid Metabolism
- Aortic Diseases
Background:
- Abnormalities in serum lipids and lipoproteins are associated with cardiovascular disease risk.
- The prognostic value of lipid profiles for acute type A aortic dissection (AAAD) remains unclear.
- This study investigates the clinical significance of preoperative blood lipids on AAAD prognosis.
Purpose of the Study:
- To analyze the correlation between the triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio and in-hospital mortality in patients with AAAD.
- To investigate the clinical significance of preoperative blood lipids and lipoproteins on the prognosis of acute type A aortic dissection.
Main Methods:
- Retrospective collection of 361 patients who underwent AAAD surgery.
- Patients divided into three groups based on baseline TG/HDL-C ratio tertiles.
- Kaplan-Meier survival analysis, Cox proportional hazards regression, and ROC curve analysis were employed.
Main Results:
- In-hospital mortality was 22.7% among the 361 patients.
- Kaplan-Meier analysis revealed a gradual increase in in-hospital death risk with higher TG/HDL-C ratios (P < 0.001).
- Multivariate Cox regression identified TG/HDL-C ratio as a significant positive predictor of in-hospital mortality (HR = 1.472, P = 0.019) after adjusting for other risk factors.
Conclusions:
- Patients with AAAD exhibit significant abnormalities in blood lipid metabolism.
- Serum TG/HDL-C levels are positively correlated with in-hospital mortality in AAAD patients.
- The TG/HDL-C ratio may serve as a valuable prognostic indicator for AAAD.
Background:
In recent years, abnormalities in serum lipids and lipoproteins have been shown to be associated with cardiovascular disease risk. However, their prognostic value for acute type A aortic dissection is unclear. This study analyzed the correlation between triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio and in-hospital mortality in patients with AAAD, and aimed to investigate the clinical significance of preoperative blood lipids and lipoproteins on the prognosis of acute type A aortic dissection.
Methods:
A total of 361 patients who underwent type A aortic dissection surgery in Fujian Cardiac Medical Center from June 2018 to March 2020 were retrospectively collected. According to the baseline TG/HDL-C ratio, the patients were divided into 3 groups according to the tertile method, the low TG/HDL-C ratio T1 group (< 1.18) and the middle TG/HDL-C ratio T2 group (1.18-1.70). T3 group with high TG/HDL-C ratio (> 1.70). Kaplan-Meier was used for survival analysis, and Cox proportional hazards regression model was used to analyze the factors affecting the prognosis of patients. The receiver operating characteristic (ROC) curve was used for the diagnostic efficacy.
Results:
Among the 361 patients in this study, the mean age was 52.4 ± 11.3 years, 73 (20.2%) were female, and 82 (22.7%) died in hospital. Kaplan-Meier curve showed that with the increase of TG/HDL-C ratio, the risk of in-hospital death gradually increased (P < 0.001). Multivariate Cox regression analysis showed that age (HR = 1.031), body mass index (HR = 1.052), hypertension (HR = 3.491), white blood cells (HR = 1.073), TG/HDL-C ratio (HR = 1.604), MODS (HR = 1.652) was positively correlated with in-hospital mortality (P < 0.05). After adjusting for age, sex, and other risk factors, a significant association was found between the TG/HDL-C ratio and in-hospital mortality for acute type A aortic dissection (HR = 1.472, 95% CI, 1.354-3.451, P = 0.019).
Conclusion:
Patients with type A aortic dissection have obvious abnormal blood lipid metabolism, and serum TG/HDL-C levels are positively correlated with in-hospital mortality in patients with AAAD.
