Values are mean ± SD (only triglyceride values are expressed as ınterquartile range). Bold values are statistically significant (). CSFP, coronary slow flow phenomenon; NCF, normal coronary flow; LAAPD, left atrial anterior-posterior diameter; LVEF, left ventricular ejection fraction; HDL, high-density lipoprotein; LDL, low-density lipoprotein; non-DHD CCB, nondihydropyridine calcium channel blocker.
