IL-34 and coronary heart disease complicated with diabetes mellitus.

Coronary heart disease and diabetes mellitus are closely related to chronic low-grade inflammation. Interleukin-34 (IL-34) is a new member of the interleukin family discovered in recent years. It is involved in the pathophysiological process of mononuclear phagocyte system mainly via binding to colony stimulating factor-1 receptor, and it is closely related to inflammatory and autoimmune diseases.

Correlation between GPR, MHR and elderly essential hypertension with unstable angina pectoris.

Objectives: To investigate the level and significance of serum γ-glutamyl transferase-to-platelet ratio (GPR) and monocyte count to high-density lipoprotein ratio (MHR) in patients with essential hypertension (EH) and unstable angina (UA).

Methods: A total of 218 patients with coronary angiography aged ≥60 years, who were admitted to the EH hospital of the Department of Cardiac Medicine, Affiliated Hospital of Chengde Medical College, were selected from September 2018 to September 2019. They were divided into an EH+UA group (=113) and an EH group (=105).

[Association of QT dispersion, ST/heart rate slope and ST-segment depression in exercise test to evaluate restenosis after percutaneous coronary intervention].

Objective: To evaluate the sensitivity and specificity of QT dispersion (QTd) and ST/heart rate slope (ST/HRs) at the end of ECG exercise test plus ST-segment depression on diagnosing restenosis after percutaneous coronary intervention (PCI).

Methods: Between November 2001 and December 2003, 129 patients underwent PCI successfully, and they were examined 3-6 months later. At the end of treadmill exercise, QTd and ST/HRs were measured.
