ABSTRACT
Objective: The study was conducted to analyze the rationality of treatment regimens and thrombosis prophylaxis used in coronary artery intervention to compare to guidelines for treatment according to VNHA and recommendation of ACC/AHA at Interventional cardiology in Can Tho Central General Hospital. Methods: The cross-sectional study was based on the data collected from entire medical records of patients at Interventional cardiology in Can Tho Central General Hospital from August 2017 to February 2018. The rationality of the antithrombotic regimen used at the Hospital is assessed through criteria such as medical combination, dosage, time to take medicine, clinical trials during the treatment. Results: The study found that 95.6% and 90.7% were suitable for medical combination before and after PCI; 100% fit for the use of medicine; and 100% was suitable for antithrombotic agents and clinical trials during treatment time; in terms of dosage, the result showed that entrance and maintenance were 84.9% and 100% for aspirin respectively; 71.7% and 100% for clopidogrel; 100% and 94.7% for ticagrelor; 90.2-92.8% and 98.1% for enoxaparin; especially, heparin-100% anticoagulant was appropriate to recommend. Conclusion: The study showed that treatment regimens and thrombosis prophylaxis in percutaneous coronary intervention at Interventional cardiology in Can Tho Central General Hospital were quite suitable compared to the recommendations of the Heart Association. The results from the study are a scientific basis for the Hospital to maintain or consider adjustments to improve the quality of treatment, ensure the effectiveness and safety of patients.
ABSTRACT
Objective To explore the possible causative factors of appearance of ventricular fibrillation (VF) during emergency percutaneous coronary intervention (PCI) in patients with acute inferior myocardial infarction. Methods Five hundred and seventy two patients with acute inferior myocardial infarction who underwent emergency PCI 24 hours after onset from May 2016 to May 2018 in Cangzhou People's Hospital were enrolled, they were divided into a VF group (52 cases) and a non-VF group (NVF, 520 cases) according to whether VF occurred or not during PCI. The differences in clinical data, characteristics of coronary artery disease and coronary artery score (Gensini score) between the two groups were compared; multivariate Logistic regression analysis was used to analyze the risk factors related to the occurrence of VF during emergency PCI; the receiver operating characteristic curve (ROC) was drawn to evaluate the efficacy of each risk factor. Results There were no statistical significant differences in sex, age, past histories of drinking alcohol, smoking, hypertension, diabetes, previous use of β blockers, aspirin, the peak values at admission of systolic blood pressure, heart rate, creatine kinase isoenzyme (CK-MB) and cardiac troponin I (cTnI), etc between the two groups (all P > 0.05). The proportions of patients with grade 0 blood flow in myocardial infarction thrombolysis (TIMI) before recanalization, with high thrombus load, criminal vessels being right coronary artery (RCA) and proximal segment of RCA, Gensini score in VF group were significantly higher than those in NVF group [TIMI 0: 80.8% (42/52) vs. 58.1% (302/520), high thrombus load: 71.2% (37/52) vs. 58.1% (302/520), criminals being RCA: 84.6% (44/52) vs. 73.7% (383/520), the occlusion site of infarction-related artery (IRA) being the proximal segment of RCA: 61.5% (32/52) vs. 41.2% (214/520), Gensini scores: 93.84±16.48 vs. 61.37±20.01, all P < 0.05]. The multiple logistic regression analysis showed that the risk factors for VF occurrence during emergency PCI for patients with acute inferior myocardial infarction included the criminals being RCA [odds ratio (OR) = 1.967, 95% confidence interval (95% CI) = 1.696-3.015, P =0.032], TIMI blood flow grade 0 before re-canalization (OR = 3.032, 95%CI = 1.248-3.675, P = 0.043), the occlusion site of infarction-related artery (IRA) being the proximal segment of RCA (OR = 2.288, 95%CI = 1.458-3.895, P =0.024), Gensini score (OR = 6.558, 95%CI = 2.168-13.359, P = 0.001] and high thrombus load (OR = 1.781, 95%CI =1.016-3.017, P = 0.033); they all were risk factors of occurrence of ventricular fibrillation during emergency PCI in patients with acute inferior myocardial infarction (all P < 0.05). ROC curve analysis showed that TIMI blood flow grade 0 before re-canalization, Gensini score and higher thrombus load had certain predictive value for VF occurrence during emergency PCI for acute inferior wall myocardial infarction; the area under ROC curve (AUC) was 0.613, 0.869 and 0.605, and 95% CI was 0.540-0.687, 0.787-0.969 and 0.521-0.675, the P value was 0.007, 0.000 and 0.012, respectively, suggesting that Gensini score had moderate predictive value for intra-operative VF, while the predictive values of TIMI blood flow grade 0 before re-canalization and higher thrombus load were relatively low. When the Gensini score had an optimal cutoff value of 96.50, the sensitivity was 85.50% and the specificity was 81.20%. Conclusion The risk factors of VF occurrence in emergency PCI for patients with acute inferior myocardial infarction are criminal vessel RCA, TIMI blood flow grade 0 before re-canalization, IRA occlusion site being proximal segment of RCA, Gensini score and high thrombus load; pre-recanalization TIMI blood flow grade 0, Gensini score and higher thrombus load all have certain predictive value for the occurrence of VF in emergency PCI for acute inferior myocardial infarction.

ABSTRACT
Objective To evaluate the efficacy and safety of direct stenting technique in emergent percutaneous coronary intervention(PCI)for pa?tients with acute myocardial infarction(AMI). Methods Totally 460 consecutive patients with acute myocardial infarction who underwent emergent PCI during August 2010 to July 2013 were involved,among whom 346 patients were assigned to the control group(traditional balloon dilation and stenting),114 patients were assigned to the experiment group(direct stenting). The safety and efficacy of direct stenting technique was observed. Results In the control group,7 cases had no reflow during operation,2 cases had reflow after the pre?expansion and 5 cases after stent implanta?tion,no similar cases in the experiment group(P=0.125 9). The follow?ups showed the control group had 2 cases of major adverse cardiac events including 1 case of acute stent thrombosis who required urgent revascularization,and 1 case of cardiac death at four days after operation;the experi?ment group had 1 case of stent thrombosis,there was no statistically significant difference(P=0.730 7). Conclusion Direct stenting technique may be performed selectively for certain coronary diseases when performing emergent PCI for AMI.
ABSTRACT
Objective To compare the effect of hemostasis of puncture point of radial artery be-tween using modified mi- type elastic bandage and TR- Band tourniquet after the operation of coronary in-tervention. Methods 142 patients who were to undergo transradial coronary intervention were divided in-to the observation group (73 cases)and the control group(69 cases). The observation group applied modi-fied mi- type elastic bandage and the control group adopted TR- Band tourniquet. The effect of hemostasis, discomfort degree and incidence rate of local complication were observed in the two groups. Results The success rate of hemostasis of the observation group (98.63%) was higher than that of the control group (94.20%), but the difference between two groups was of no statistical significance. For the discomfort de-gree: the feeling of pain was higher in the control group, incidence of swelling was higher in the observa-tion group,the difference between the two groups had statistical significance,for the incidence of numb-hess,the test was of no statistical significance,for the local skin complication,the difference between two groups was of no statistical significance. Conclusions Putting modified mi- type elastic bandage into the application after the operation of coronary intervention,we find that choosing material is convenient,it is easy to observe and operate,the effect of hemostasis is safe and reliable,the rate of complication is low. So it is one safe, effective and ecnomical hemostasia method.
ABSTRACT
Objective To study the applied value of invasive arterial blood pressure monitoring in the diagnose and treatment of coronary artery intervention. Methods The dynamic changes of ECG, the non-invasive blood pressure, the invasive arterial blood pressure monitoring and the clinical performance were ob-served in 163 patients in the process of coronary artery intervention (CAI). Then the invasive arterial blood pressure change and the non-invasive blood pressure change were compared. Results The change rates of invasive arterial blood pressure were higher than that of non-invasive arterial blood pressure. The difference of both changes had statistical significance. The invasive blood pressure decreased and wave forms changed in 26 cases. These reflected sensitively the patients' condition and the issues in the process of CAI. Conclusions To strengthen the invasive arterial blood pressure monitoring can improve the success rate of CAI more effec-tively and reduce the complication.
ABSTRACT
Objective To explore the best position in bed for the patients who have under the operation of percutaneous coronary intervention (PCI) and then used heparin sodium within 24 hours. Methods The 159 patients were divided into two groups randomly:the experimental group and the control group. After the PCI, the subjects in these two groups will rest in bed by two ways. Using McGill′s present Pain Index to evaluate hematoma, using the PPI to evaluate the pain of back, using the STAI to evaluate the condition of anxiety, write the number of patient who have anuresises. Results There are no significant difference between two groups in wound blooding, while the difference of back pain, anxiety and the anuresises are significant between two groups. Conclusion The position of half-lie is safe and comfortable for the patients who have under the operation of PCI.
