ABSTRACT
OBJECTIVE@#To observe the immediate effect and safety of Shexiang Tongxin dropping pills (, STDP) on patients with coronary slow flow (CSF), and furthermore, to explore new evidence for the use of Chinese medicine in treating ischemic chest pain.@*METHODS@#Coronary angiography (CAG) with corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) was applied (collected at 30 frames/s). The treatment group included 22 CSF patients, while the control group included 22 individuals with normal coronary flow. CSF patients were given 4 STDP through sublingual administration, and CAG was performed 5 min after the medication. The immediate blood flow frame count, blood pressure, and heart rate of patients before and after the use of STDP were compared. The liver and kidney functions of patients were examined before and after treatments.@*RESULTS@#There was a significant difference in CTFC between groups (P0.05).@*CONCLUSIONS@#The immediate effect of STDP in treating CSF patients was apparent. This medication could significantly improve coronary flow without affecting blood pressure or heart rate. Our findings support the potential of Chinese medicine to treat ischemic chest pain.

Objective To discuss the value of ischemia modified albumin (IMA) in the early diagnosis of acute coronary syndrome (ACS). Methods The IMA,cTnI, CK-MB and ECG were detected in 103 patients with suspected ACS (45 cases of NICP and 58 cases of ACS) within 5 hours of acute chest pain onset respectively. 30 healthy subjects were served as normal controls. Receiver operating characteristic (ROC) analysis was used to determine the optimal cutoff of this assay for identifying individuals with ACS from non-ischemic individuals (nonischemic chest pain, NICP). Results of IMA,cTnI,CK-MB and ECG were correlated with the final diagnosis and their diagnostic sensitivities for ACS were evaluated. Results The results suggested that acute phase IMA values between those with ACS and NICP were (89.66 ± 25.82) U/ml, (46.79 ± 17.20) U/ml respectively and showed significant difference. Area under the curve (AUC) of the ROC was 0.935. As the Cut-off point was 71.6 U/ml, the sensitivity, specificity, PPV and NPV of IMA were 90.6%, 71.4% , 82.8% and 83.3%, respectively. The simutanious positive rate of IMA for ischemia origin were 29.3% of cTnI,27.6% of CK-MB and 48.3% of ECG(P＜ 0.01). Conclusions Plasma IMA assessment is valuable for early diagnosis of acute coronary ischemia, and will improve the early diagnostic sensitivity of ACS significantly.
ABSTRACT
BACKGROUND: The causes of chest pain vary but the leading cause of chest pain is ischemic heart disease. Mortality from ischemic chest pain has increased more than two fold over the last ten years. The purpose of this study was to determine the data necessary for rapid treatment of patients with signs and symptoms of ischemic chest pain in the emergency department (ED). MATERIALS AND METHODS: We interviewed 170 patients who had ischemic chest pain in the emergency department of Yeungnam University Hospital over 6 months with a protocol developed for the evaluation. The protocol used included gender, age, arriving time, prior hospital visits, methods of transportation to the hospital, past medical history, final diagnosis, and outcome information from follow up. RESULTS: Among 170 patients, there were 118 men (69.4%) and the mean age was 63 years. The patients diagnosed with acute myocardial infarction (AMI) were 106 (62.4%) and with angina pectoris (AP) were 64 (37.6%). The patients who had visited another hospital were 68.8%, twice the number that came directly to this hospital (p0.05). The patients who had a total time delay of over 6 hours was similar 54.8% in the AMI group and 57.9% in the AP group (p>0.05). As a result, only 12.2% of the patients with an AMI received thrombolytics, and 48.8% of them had a simultaneous percutaneous coronary intervention (PCI). In the emergency department 8.5% of the patients with an AMI died. CONCLUSION: Timing is an extremely important factor for the treatment of ischemic heart disease. Most patients arrive at the hospital after a long time lapse from the onset of chest pain. In addition, most patients present to a different hospital before they arrive at the final hospital for treatment. Therefore, important time is lost and opportunities for treatment with thrombolytics and/or PCI are diminished leading to poor outcomes for many patients in the ED. The emergency room treatment must improve for the identification and treatment of ischemic heart disease so that patients can present earlier and treatment can be started as soon as they present to an emergency room.
