Underlying Clinical Dataset for "Correlation between Myocardial Microalternans Index and Left-Ventricular Ejection Fraction in Stable Coronary Artery Disease"

This dataset contains anonymized raw clinical data underlying the study “Correlation between Myocardial Microalternans Index and Left-Ventricular Ejection Fraction in Stable Coronary Artery Disease”. The dataset includes individual-level variables used in all analyses reported in the article, including demographic characteristics, cardiovascular risk factors, coronary lesion characteristics, Myocardial Microalternans Index (MMI), and left ventricular ejection fraction (LVEF). The data support the correlation and ROC analyses presented in the manuscript and include the values underlying all summary statistics and figures. All direct personal identifiers were removed prior to data sharing.
