A total of 749 natural menopausal elderly women aged \u226560 years who were hospitalized in the Department of Cardiology, First Affiliated Hospital of the University of Science and Technology of China and underwent coronary angiography for the first time were divided into CHD group (527 patients) and non-CHD group (222 patients). The clinical data parameters used in this analysis were chosen based on literature support and clinical findings related to CHD in elderly postmenopausal women. The clinical data of the two groups were compared, and the predictive value of the TyG index and TG\/HDL-C was analyzed by m ultivariable logistic regression analysis and the receiver operating characteristic (ROC) curves.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Multivariable logistic regression analysis showed that hemoglobin (Hb), high-sensitivity C-reactive protein (hs-CRP), TyG index, TG\/HDL-C, daily sleep duration and glycosylated hemoglobin (HbA1c) were independent influencing factors of CHD in elderly postmenopausal women (\n                      <jats:italic>P<\/jats:italic>\n                      &lt;\u00a00.05).
