Insights
Stress hyperglycemia independently predicts large thrombus burden in non-diabetic ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention. This finding highlights hyperglycemia
Area of Science:
- Cardiology
- Endocrinology
- Biomedical Research
Background:
- Hyperglycemia is known to affect platelet function and fibrin structure.
- Understanding hyperglycemia's role in acute cardiac events is crucial for patient outcomes.
Purpose of the Study:
- To investigate the predictive value of hyperglycemia for thrombus burden in non-diabetic patients with ST-segment elevation myocardial infarction (STEMI).
- To assess the association between stress hyperglycemia and large thrombus burden (LTB) in patients undergoing primary percutaneous coronary intervention (PPCI).
Main Methods:
- A cohort of 619 non-diabetic STEMI patients undergoing PPCI was analyzed.
- Patients were categorized based on thrombus burden (grades 4 as LTB) and stress hyperglycemia (blood glucose >180 mg/dL).
- Multivariate logistic regression was used to identify independent predictors of LTB.
Main Results:
- 11.0% of patients experienced stress hyperglycemia, and 36.0% had LTB.
- Patients with LTB had significantly higher admission blood glucose levels compared to those with small thrombus burden (145.9 ± 43.1 mg/dL vs. 135 ± 39.1 mg/dL, P=0.002).
- Stress hyperglycemia was identified as an independent predictor of LTB (OR: 3.025, P=0.019).
Conclusions:
- Admission hyperglycemia is significantly associated with large thrombus burden in STEMI patients.
- Hyperglycemia may play a critical role in the development of coronary thrombus.
- These findings suggest hyperglycemia as a potential therapeutic target to improve outcomes in STEMI.
Abstract:
: It is established that hyperglycemia directly effects the platelet functions and fibrin structure. In this study, we aimed to investigate the predictive value of hyperglycemia on thrombus burden in nondiabetic patients with ST-segment elevation myocardial infarction (STEMI) who underwent to primer percutaneous coronary intervention (PPCI). We enrolled 619 nondiabetic patients with STEMI who received PPCI. Patients were divided two groups according to thrombus burden. Stress hyperglycemia was determined as blood glucose concentration more than 180 mg/dl and angiographic coronary thrombus burden was scored based on thrombolysis in myocardial infarction thrombus grades. Patients with thrombus grades 4 were defined as large thrombus burden (LTB), patients with thrombus burden less than thrombus grades 4 were defined as small thrombus burden. A total of 68 (11.0%) STEMI patients had stress hyperglycemia, while 223 (36.0%) patients had LTB. Sex, the prevalence of hypertension, smoking, and dyslipidemia were not different between the thrombus burden groups (P > 0.05 for all parameters). Compared with the patients with small thrombus burden, the patients with LTB were had significantly higher admission blood glucose concentrations (135 ± 39.1 mg/dl vs. 145.9 ± 43.1, P = 0.002, respectively). The multivariate logistic regression analysis demonstrated that stress hyperglycemia is an independent predictor of LTB (odds ratio: 3.025, confidence interval 1.200-7.622, P = 0.019). Admission hyperglycemia is associated with the LTB which cause adverse cardiac outcomes. Hyperglycemia may play a role on thrombus development.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
