The aim of the research was to evaluate the efficacy and safety associated with Shexiang Tongxin Dropping Pills combined with conventional therapy for patients with coronary heart disease(CHD). We searched 8 electronic databases up to November 2020, including PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, VIP and SinoMed. Eligible studies were clinical trials of Shexiang Tongxin Dropping Pills combined with conventional therapy used in the treatment of coronary heart disease(CHD). The Meta-analysis was performed using STATA 15 software. A total of 21 RCTs(n=2 186) were shortlisted for the Meta-analysis. The results of efficacy evaluation showed that the total effective rate of Shexiang Tongxin Dropping Pills combined with conventional therapy was higher than that of conventional therapy of coronary heart disease(RR=1.20, 95%CI[1.15, 1.26], Z=8.63, P<0.001). Furthermore, Shexiang Tongxin Dripping Pills combined with conventional therapy had better effect on electrocardiogram efficacy(RR=1.24, 95%CI[1.16, 1.34], Z=5.98, P<0.001) and the number of angina attacks(SMD=-2.30, 95%CI[-3.47,-1.14], Z=3.88, P<0.001), the duration of angina attack(SMD=-2.31, 95%CI[-3.07,-1.55], Z=5.97, P<0.001), with lower levels of LDL-C(SMD=-0.73, 95%CI[-1.32,-0.14], Z=2.42, P=0.016), TC(SMD=-1.16, 95%CI[-1.35,-0.96], Z=11.56, P<0.001) and TG(SMD=-0.87, 95%CI[-1.06,-0.68], Z=8.97, P<0.001), and higher levels of HDL-C(SMD=0.87, 95%CI[0.02, 1.71], Z=2.00, P=0.045). The results of safety evaluation showed that the incidence of adverse reactions of Shexiang Tongxin Dropping Pills combined with conventional therapy was lower than that of conventional therapy of coronary heart disease(RR=0.45, 95%CI[0.22, 0.91], Z=2.23, P=0.026). There were significant differences in the above outcome indexes between the two groups. After the Harbord method test, the total effective rate outcome index has publication bias, but the sensitivity analysis of the cut-and-fill method suggested that the result was stable. In general, limited by the quantity and quality of included literature, more high-quality studies are needed to further verify the conclusions of this study.

Bupivacaine is widely used as a local anesthetic. Central nervous system (CNS) and cardiovascular toxicity are well known side effects. However, there has been no report of bupivacaine-induced myocardial injury. We present a case of bupivacaine cardiac toxicity mimicking an acute non-ST segment elevation myocardial infarction, which was eventually diagnosed as bupivacaine-induced cardiac toxicity without CNS toxicity. As soon as a healthy young woman at a private clinic was given a spinal anesthesia of 6mg bupivacaine for hemorrhoidectomy, she developed arrhythmia and hypotension. She was transferred to our emergency room. There was an accelerated idioventricular rhythm with ST segment depression on electrocardiogram, coarse breathing sounds with rales on whole lung field and a butterfly sign on the chest radiograph. 2D transthoracic echocardiography (TTE) revealed reduced left ventricle systolic ejection fraction (approximately 27%). There was regional wall motion abnormality of the left ventricle on 2D TTE and the cardiac marker was increased. We diagnosed the patient as having acute non-ST segment elevation myocardial infarction but her impaired cardiac function improved gradually. On the seventh day from admission, there was a complete spontaneous recovery of cardiac function, and coronary angiography revealed a normal coronary artery. Therefore, we firmly believe that bupivacaine directly injures the cardiac cell.

PURPOSE: Opioids may affect changes in the corrected QT interval (QTc) during anesthetic induction. This study examine whether a single bolus of remifentanil would prolong QTc after laryngeal mask airway (LMA) insertion during sevoflurane induction. MATERIALS AND METHODS: Forty women of American Society of Anesthesiologists physical status 1 (ASA PS1) undergoing gynecological surgery were studied. All patients were induced using three vital capacity inhalation inductions with 5% sevoflurane. Two minutes after induction, the inspiratory concentration of sevoflurane was reduced to 2%. Using double-blinded randomization, patients were allocated into one of two groups, receiving either saline (placebo group, n = 20) or 0.25 microg.kg-1 remifentanil (remifentanil group, n = 20) over a period of thirty seconds. Sixty seconds later, LMA insertion was performed. Recordings were taken with a 12-lead electrocardiogram at baseline, 2 min after induction and 1 and 3 min after LMA insertion. QTc was calculated by Bazett's formula. The mean arterial pressure (MAP) and heart rate (HR) were also measured at each time point. RESULTS: The QTc interval was significantly prolonged in the placebo group as compared to the remifentanil group at 1 min after LMA insertion (467.8 +/- 16.5 vs. 442.7 +/- 21.3 ms, p < 0.001). However, there was no significant difference in QTc at 3 min after LMA insertion between the two groups. MAP and HR were significantly higher in the placebo group (p < 0.001). CONCLUSION: A single bolus of remifentanil is safe method to attenuate prolonged QTc associated with insertion of LMA.

BACKGROUNDImplantable cardioverter defibrillator (ICD) is the only effective therapy in patients with life threatening ventricular arrhythmias. Inappropriate detection and therapy by ICDs are the most common causes of side effects that affect the quality of life in ICD recipients. This study evaluated the incidence and causes of inappropriate detection and therapy by ICDs in patients in our hospital.

METHODSFrom January 2000 to December 2005, fifty patients who received ICD implantation for ventricular arrhythmias for prevention of sudden cardiac death were evaluated in this study. Each ICD was programmed using clinical arrhythmic and cardiac data of the patient before discharge. Patients were followed up by standard schedule after implantation and all data retrieved from each device were collected and saved for further analysis.

RESULTSNo arrhythmic event was detected in 12/50 (24%) patients during the period of follow-up. Among the remaining patients, 11 (22%) experienced inappropriate detections and therapies during follow-up in this study. ICD detected 383 ventricular tachyarrhythmia (VT) and 108 ventricular fibrillation (VF) episodes and delivered 678 therapies. In VT group, ICD delivered 413 antitachycardiac pacings (ATPs) and 118 shocks, among which 78 ATPs and 9 shocks were initiated by 55/383 (14.3%) inappropriate detections. In VF group ICD delivered 147 shocks, among which 56 shocks were initiated by 28/108 (26.9%) inappropriate detections. Overall, more than 50% of these episodes were caused by atrial fibrillation (AF) with rapid ventricular response, followed by electromagnetic or myopotential interference. In addition, most inappropriate therapies occurred within one year after ICD implantation.

CONCLUSIONSAbout one fifth of patients experienced ICD inappropriate detection and therapy after implantation. The main cause was AF with rapid ventricular response, followed by electromagnetic or myopotential interference.
