in this trial, after the evaluation of exercise stress test shows that underwent PCI in acute myocardial infarction treated cardiac function recovery and improve the efficacy of myocardial ischemia is clear, the principle is to obtain a stable PCI occlusion patency rate, to achieve complete reperfusion is related to the expansion of a restricted necrotic myocardium and hibernating myocardium or to promote functional recovery of stunned myocardium,[link widoczny dla zalogowanych], reduce left ventricular remodeling, protection or restoration of damaged left ventricular function, exercise test , due to the improvement of myocardial blood supply, making the heart pump function improved significantly, resulting in improved exercise tolerance in heart. And because the drug treatment group on the low opening rate of vascular occlusion and occlusion of blood vessels after the opening of the low perfusion, but limited the expansion of necrotic myocardium, hibernating myocardium or to promote functional recovery of stunned myocardium of little impact recovery of cardiac function and myocardial ischemia improved, the majority of this group of patients there is myocardial ischemia during exercise treadmill test and the performance of left ventricular dysfunction. Through this test, we can be sure emergency PCI treatment not only reduces AMI mortality and the incidence of cardiac accidents, recovery of cardiac function and myocardial ischemia have a clear help to improve, but also improve the prognosis of AMI patients and quality of life. But after AMI has markedly impaired left ventricular function (particularly left ventricular function was impaired), emergency PCI treatment had little effect on cardiac function recovery; in the presence of multi-vessel disease who, due to the treatment only for emergency PCI occlusion of blood vessels and other vascular lesions in the heart there is also increased ischemic tolerance of the situation. Therefore, after emergency PCI treadmill test in the evaluation of therapy on cardiac function, we get an affirmative answer: Emergency PCI treatment on cardiac function recovery is effective and the prognosis of AMI can provide objective evidence.

1.1 General information: 125 patients with clinical symptoms, electrocardiogram, myocardial enzymes such as diagnosis, were acute myocardial infarction within 6 hours of treatment, of whom 97 males, 28 females, aged 35 to 72 years, an average of 58 years; 85 routine PTCA treatment,[link widoczny dla zalogowanych], 40 patients drug treatment rules (including thrombolytic therapy), after discharge, and medication can rule followed up by your doctor , and by the general guidance of cardiac rehabilitation exercise therapy. Selected patients had no pulmonary insufficiency, liver and / or renal insufficiency decompensation of motor functions and other diseases.
References:
acute myocardial infarction occurs when myocardial necrosis was the ring to expand, with time and increased myocardial ischemic necrosis of the infarct area, weakening or loss of contraction, leading to uncoordinated contraction of the heart, decreased heart function, blood vessels and timely opening of the blood reperfusion can limit the extension of myocardial necrosis; outer myocardial infarction or hibernating myocardium as stunned myocardium, the blood flow re- restore function after reperfusion, this section is the heart of myocardial viability [1]. Therefore, AMI occurred, timely revascularization,[link widoczny dla zalogowanych], blood flow reperfusion is the key to treatment. Present in blood vessel treatment, treatment with intravenous thrombolysis, PCI, surgical bypass grafting (CABG) surgery, according to the report, intravenous thrombolysis was only opened 60 to 70%; opening of blood flow to TIMI Ⅲ class less than 60%. The emergency room can get a stable occlusion PCI patency rates, to achieve complete reperfusion, 100% of the blood flow to TIMI Ⅲ level, especially in the bracket support continuous improvement and drug use, to overcome the PCI after the occurrence of stent thrombosis, and venous thrombolysis with coronary artery than in the promotion of open and reduce re-infarction, improve left ventricular function and clinical effect of the more prominent [2]. To improve exercise tolerance in heart.

Exercise stress test in the evaluation of intervention for acute myocardial infarction


Of: Chen Liang Yan Hainan Island with Miss Ophelia Chan Chiu Yi




Abstract: Objective: To observe the cardiac treadmill test intervention (PCI) for acute myocardial infarction ( AMI) and myocardial ischemia and cardiac function recovery to improve the situation. Methods: The 1999-2003 hospital admissions of patients with acute myocardial infarction 125 patients were treated with PCI and drug therapy for 6 months after the treadmill exercise tolerance test and the different performance of left ventricular function analysis. Results: PCI for acute myocardial infarction cardiac function after myocardial ischemia and improved recovery and a clear effect. Conclusion: Emergency PCI AMI treatment not only reduces the mortality and the incidence of cardiac accidents, recovery of cardiac function and myocardial ischemia have a clear help to improve, but also improve the prognosis of AMI patients and quality of life significantly better than drug treatment group .

PCI treated patients in the exercise treadmill test was positive anteroseptal, anterior, extensive anterior wall, high lateral myocardial infarction more common, especially in extensive anterior wall myocardial infarction, the proportion of large, of 7 cases (77.8%), inferior or right ventricular infarction are rare, multi-vessel disease who basically have positive performance; drug treatment group no significant difference in infarct area.
Abstract: Objective: To observe the recovery of cardiac function and the improvement of the myocardial ischemia of the AMI patient treated by PCI via Cardiac Flat Motion Tester. Method: A total of 125 cases of AMI patients treated in our hospital from 1999 to 2003 were respectively treated by PCI and drug. After 6 months, the motor tolerance and the left ventricle function of them were analyzed via Cardiac Flat Motion Tester.Result: After the AMI patient treating by PCI, the recovery of cardiac function and the improvement of the myocardial ischemia were significant. Conclusion: Treating the AMI by PCI not only could decline the case fatality rate and the cardiac contingent event incidence, but also was helpful for the recovery of cardiac function and the improvement of myocardial ischemia and could improve the AMI patient's prognosis and life quality, with treatment effect significantly higher than that in drug treatment group.






1.2 Observation Methods: All patients admitted to hospital after a clear diagnosis of aspirin 300mg, 250mg or Ticlid or clopidogrel Taijia 100mg 300mg,[link widoczny dla zalogowanych], regular treatment after 6 months, the program line by Bruce treadmill test, according to the patients in the test, ST segment changes (elevation or depression),[link widoczny dla zalogowanych], blood pressure, angina pectoris, positive standards for the exercise less than 2min.
cardiac treadmill test was to evaluate aerobic exercise capacity and left ventricular function of a good method of clinical patients with acute myocardial infarction and myocardial ischemia and cardiac function recovery is an objective to improve the effective and also has been on The prognosis of these patients and to provide general evaluation of the quality of life. Studies in cardiac rehabilitation, and has been on the treadmill test to patients with heart disease treatment for each stage of testing, a clinical evaluation of cardiac aerobic exercise capacity and left ventricular functional recovery standards.

Observing the PCI Treatment of Acute Myocardial Infarction (AMI ) Via Cardiac Flat Motion Tester
Key words: PCI; Acut myocardial infarction; Necrotic myocardium hibernation; Myocardium stunned ; Myocardium; Blood flow reperfusion acute myocardial infarction (AMI) occurs when the necrotic myocardium was ring expanded to increase with time. Cardiac intervention (PCI) in acute myocardial infarction treatment of the vascular obstruction timely reperfusion, thereby limiting the increase in myocardial necrosis, but also a good hibernating myocardium or to promote recovery of stunned myocardium, is currently the mainstream treatment of acute myocardial infarction methods. Now in our hospital from 1999 to 2003 admissions of 125 patients with acute myocardial infarction patients treated for 6 months later the results of exercise stress test is as follows.
