Data are presented as numbers with frequencies in parentheses or proportions and frequencies in parentheses along with mean ± standard deviation. Abbreviations: BMI, body mass index; CCTA, coronary CT angiography; CAD, coronary artery disease; ECG, electrocardiogram; kV, kilovolt; bpm, beats per minute; R–R interval, elapsed time percentage between two R waves of the QRS signal on the electrocardiogram. * refers to values presented in median and interquartile ranges in square brackets.
