NOMOGRAM CONTAINING SIMPLE ROUTINE CLINICAL AND BIOCHEMICAL PARAMETERS CAN PREDICT PATHOLOGIC VENTRICULAR REMODELING...

Area of Science:

• Cardiology
• Biomedical Engineering
• Clinical Research

Background:

• Heart failure is a major global health concern, often stemming from ischemic heart disease.
• Ventricular remodeling, characterized by increased ventricular volumes, is a key mechanism in heart failure development.
• Early identification of patients at risk for adverse remodeling post-myocardial infarction is crucial.

Purpose of the Study:

• To identify clinical and biochemical predictors of pathologic ventricular remodeling one year after ST-segment elevation myocardial infarction.
• To develop and validate a predictive nomogram for adverse ventricular remodeling.

Main Methods:

• Prospective observational study of 101 patients with ST-segment elevation myocardial infarction.
• Percutaneous coronary intervention within 12 hours and Thrombolysis in Myocardial Infarction III flow achieved.
• Nomogram developed using NTproBNP, aspartate transaminase, systolic blood pressure, and culprit artery; validated with ROC analysis.

Main Results:

• The developed nomogram demonstrated a high predictive value for pathologic ventricular remodeling (Area Under Curve = 0.907).
• Key predictors included NTproBNP and aspartate transaminase levels 12 hours post-reperfusion, admission systolic blood pressure, and culprit coronary artery.
• The nomogram achieved 91.4% sensitivity and 74.0% specificity at a threshold of -3.54.

Conclusions:

• A novel nomogram effectively predicts pathologic left ventricular remodeling after myocardial infarction.
• This low-cost, widely available tool can identify at-risk patients early (12 hours post-reperfusion).
• Further validation is needed, but the nomogram shows promise for guiding early clinical interventions.
