Emergency And Undergoing Elective Percutaneous Coronary Intervention In Left Anterior Descending Branch Of Coronary Artery Disease Clinical Research

Objective:Comparative analysis the clinical emergency and undergoing elective percutaneous coronary intervention in left anterior descending branch of coronary artery disease clinical curative effect and safety evaluation.Methods:A retrospective analysis of changzhi from March 2013 to March 2014 the Affiliated Heping Hospital of Changzhi Medical College and Lu an Mining Affairs Hospital affiliated in room 102 cases of emergency or haing electie PCI treatment of left anterior descending coronary artery disease patients wich is STEMI(ST-segmentelevationmyocardialinfarction,STEMI) clinical data. Emergency and haing electie PCI surgery patients, in conventional coronary angiography, by two or more experienced cardiologists were to infarct blood vessels. Emergency group screening line immediately after the PCI surgery, patients with elective in further treatment such as thrombolysis, stable plaques around 10 d- 14 d, haing electie PCI surgery. Collect PCI in patients with left anterior descending stenosis before and after operation, blood flow is generally analyzed. SNR in the situation, the expansion operation was observed after immediate angiography results average residual rate and acute occlusion, perforation of the tube wall tear, mezzanine, arterial spasm, complications and adverse events. Success, the success rate of surgery, postoperative stenting recanalization situation and situation of cardiac function evaluation, and carries on the comparison to hospitalization expenses and hospitalization time. Compare two groups of death, heart failure, malignant arrhythmia, major bleeding occurred after operation, recurrence of malignant events such as myocardial infarction, angina. All data using SPSS13.0 statistics software.Results:1. The preoperative general situation analysis: the emergency and haing electie surgical preoperative age, sex, laboratory examination index, time to see a doctor, preoperative incidence of angina pectoris, preoperative stenosis degree, infarction vascular blood flow condition, suchas the statistical comparison, there were no statistically significant difference.2. The situation is: in the operation of emergency incidence of SNR and names of group were 6.45% and 2.50% respectively; Expansion after immediate angiography results average residual rate is 19.35% and 19.35%. Emergency group of acute coronary artery occlusion and acute thrombosis in 1 case, wall tear in 1 case, artery convulsion occurred in 2 cases, coronary artery perforation in 1 case. Haing electie surgical group branch occlusion occurred in 1 case, artery spasm in 1 case. Above indicators by the statistical analysis of the difference is not significant(P > 0.05).3. The situation is: after the emergency PCI surgery success rate of 91.94%, less than 95.0% success rate of elective surgical procedures. Two groups of stenting success rate were 90.32% and 100% respectively, the difference was statistically significant(P < 0.05). After reviewing IRA contribution rate of the two groups were 93.55% and 80.00% respectively, IRA stenosis degree was 10.91 + /- 3.78% and 8.81 + /- 3.63% respectively, left ventricular ejection fraction were 50.69 + /- 3.01 and 52.75 + /- 3.47 difference was statistically significant(P < 0.05). Compared two groups of hospitalization days and hospitalization expenses, the emergency group were lower than the quiet group, the difference was statistically significant(P < 0.05). 4. Comparison of PCI postoperative malignant events: death in 1 cases, emergency group names of group 0 example. Nausea arrhythmia of 2cases and 1 cases respectively. Major bleeding after the emergency group in 1 cases, marked in 0 case, again hair myocardial infarction 3 cases and 1 cases respectively. Nausea events above comparison, there were no statistically significant difference between the two groups(P > 0.05).Conclusion:Emergency PCI can timely dredge injured blood vessels and relieve symptoms, improve quality of life,and the degree of stenosis of postoperative infarct blood vesseis is small,but the success rate of surgery and postoperative complications is more, elective PCI is characterized by a high success rate of surgery, postoperative quality of life. Suggestions on the choice of emergency PCI carefully, choice of elective surgical procedures in a stable condition after the line of PCI surgery as soon as possible. For the long-term complications and quality of life remains to be further research.
