Renal Dysfunction was an Independent Predictor of In-Hospital Death and Ventricular Rupture in Patients With Acute...

Area of Science:

• Cardiology
• Nephrology
• Critical Care Medicine

Background:

• Predictors of in-hospital death (In-HD) in acute myocardial infarction (AMI) patients are crucial for risk stratification.
• Existing research suggests various factors influence outcomes beyond disease severity.

Purpose of the Study:

• To investigate independent predictors of In-HD and ventricular rupture (VR) in patients experiencing their first AMI.
• To identify specific patient characteristics and comorbidities associated with increased mortality and mechanical complications.

Main Methods:

• Stepwise multivariable logistic regression analysis was employed.
• The study included 1,042 patients admitted within 48 hours of AMI symptom onset.
• Data on demographics, clinical factors, and outcomes were collected and analyzed.

Main Results:

• Renal dysfunction (RD), defined as estimated glomerular filtration rate < 60 mL/min/1.73 m², was a significant independent positive predictor of In-HD.
• Age and RD were independent predictors of VR, while diabetes also emerged as a predictor for VR.
• Hypercholesterolemia was found to be an independent negative predictor for In-HD.

Conclusions:

• Renal dysfunction (RD) is a critical independent predictor of both in-hospital death (In-HD) and ventricular rupture (VR) in the setting of initial acute myocardial infarction (AMI).
• These findings highlight the importance of assessing renal function in AMI patients for prognostication and management.
