Risk Factors and Outcome Variables of Cardiorenal Syndrome Type 1 in Acute Myocardial Infarction Patients

Area of Science:

• Cardiology
• Nephrology
• Critical Care Medicine

Background:

• Cardiorenal syndrome type 1 (CRS1) is a critical complication in acute myocardial infarction (AMI) patients.
• Understanding short-term prognostic factors is crucial for managing CRS1 in AMI.

Purpose of the Study:

• To identify risk factors associated with short-term mortality in patients with CRS1 following AMI.
• To evaluate the predictive accuracy of scoring systems for mortality in this population.

Main Methods:

• Retrospective analysis of 88 CRS1 patients hospitalized with AMI between 2011 and 2014.
• Data collected included demographics, laboratory results, and 28-day outcomes.
• Comparison of deceased versus survivor groups using logistic regression and scoring systems (APACHE II, SOFA, SAPS II).

Main Results:

• The 28-day mortality rate for CRS1 in AMI patients was 28.4%.
• Factors significantly predicting death included mechanical ventilation, elevated NT-proBNP, increased 7th-day serum creatinine, and decreased left ventricular ejection fraction (LVEF).
• APACHE II, SOFA, and SAPS II scores on day 7 showed high accuracy (AUCs 0.844, 0.803, 0.827) in predicting 28-day mortality.

Conclusions:

• Mechanical ventilation, elevated NT-proBNP, 7th-day serum creatinine, and reduced LVEF are significant predictors of mortality in AMI patients with CRS1.
• APACHE II, SOFA, and SAPS II scores on day 7 are reliable tools for predicting short-term mortality in this high-risk group.
