Shexiang Tongxin Dropping Pill combined with thrombus aspiration improves myocardial perfusion after PCI in patients with STEMI: the clinical research

Objective:To study the effect of Shexiang Tongxin Dropping Pill combined with thrombus aspiration on improving myocardial perfusion after PCI in patients with STEMI.Methods:A total of 104 patients with STEMI who received emergency PCI combined with thrombus aspiration in our hospital between May 2013 and October 2015 were selected as the research subjects and randomly divided into two groups: observation group received perioperative antiplatelet combined with Shexiang Tongxin Dropping Pill therapy, and the control group received perioperative antiplatelet therapy alone. Before treatment and 3 days after treatment, serum myocardial injury indexes, endothelial injury indexes and RAS system indexes were determined;4 weeks after treatment, serum ventricular remodeling indexes were determined. Results:3 d after treatment, serum CK, CK-MB, cTnI, cTnT, ET-1, vWF, PRA, AngII and ALD levels of both groups were significantly lower than those before treatment while NO level was significantly higher than that before treatment;serum CK, CK-MB, cTnI, cTnT, ET-1, vWF, PRA, AngII and ALD levels of observation group 3 d after treatment were significantly lower than those of control group while NO level was significantly higher than that of control group;4 weeks after treatment, serum PICP, ICTP, PIIINP, HSP47 and GDF-15 levels of observation group were significantly lower than those of control group.Conclusion: Shexiang Tongxin Dropping Pill application during perioperative period of PCI combined with thrombus aspiration can reduce myocardial cell damage and endothelial function injury as well as inhibit RAS system activation and ventricular remodeling.

Changes in plaque stability, cell apoptosis and coagulation indexes after patients with unstable angina pectoris accept adjuvant salvianolate therapy

Objective:To investigate the effect of adjuvant salvianolate therapy on plaque stability, cell apoptosis and coagulation indexes in patients with unstable angina pectoris.Methods: 92 patients with unstable angina pectoris treated in our hospital between May 2011 and August 2015 were collected, and after the treatment process and auxiliary examination results were retrospectively analyzed, they were divided into the control group (n=45) who accepted conventional treatment and the observation group (n=47) who accepted adjuvant salvianolate treatment. Before and after treatment, diasonograph was used to evaluate the plaque stability parameters of two groups of patients;ELISA was used to detect apoptosis-related molecule levels;immunoturbidimetry was used to detect blood coagulation indexes.Results: Before treatment, differences in plaque stability parameters, cell apoptosis molecules and coagulation indexes were not statistically significant between two groups of patients (P>0.05). After treatment, the plaque stability parameters plaque thickness, enhanced intensity, rise time and time to peak of observation group were significantly lower than those of control group (P<0.05);serum sFas, sFasL, fibrinogen (Fib), platelet (PLT), and D-Dimer (D-D) levels of observation group were significantly lower than those of control group while Bcl-2, prothrombin time (PT) and activated partial thromboplastin time (APTT) levels were significantly higher than those of control group (P<0.05).Conclusions: Adjuvant salvianolate treatment can increase the plaque stability, also inhibit myocardial cell apoptosis and improve the coagulation function in patients with unstable angina pectoris.
