| Due to the influence of the present-day lifestyle, Cardio-Cerebrovascular disease has become one of the main diseases which menace the human health and the quality of life. According to the statistics, there are about 8.5 million people who died for the acute myocardial infarction worldwide. In China, with the aging of the population, the incidence rate of cardiovascular disease is increasing every year and is the most frequent disease. Acute myocardial infarction (AMI) stands for the severe myocardial ischemia and necroses caused by the angiographically coronary artery stenosis or coronary artery occlusion. Its clinical manifestation is severe chest pain, normally also with heart failure, cardiac dysrhythmia and shock. It is the main reason of sudden cardiac death. As the severest type of coronary heart disease, its hazards to human health are more and more obvious. Though there are some effective therapies, like emergency percutaneous coronary intervention, thrombolytic therapy and coronary artery bypass graft surgery, the heart situation is no significant permanent improvement. Thus it is very meaningful and significant to distinguish and intervene on the coronary heart disease. For aging people, as a special group, the reoccurring of the heart disease has a certain particularity. With the age increasing, all their organs'functions, sensibility and responsiveness decrease. This leads to the clinical symptom of aging AMI patients not being obvious, and causes misdiagnosis and missed diagnosis. Therefore, analyzing all kinds of initial clinical symptoms of aging AMI patients is important for improving their recovery situation.Objective: Through the left ventricular dysfunction as the initial symptom in patients with acute myocardial infarction risk factors, atypical clinical manifestations were analyzed in order to better understand the onset of atypical symptoms of the disease in elderly patients with AMI characteristics. For future work in an early clinical diagnosis, improve treatment andreduce mortality and improve the prognosis of elderly patients to provide reference.Subjects and methods: This collection from January 2005 to January 2010, First Affiliated Hospital of Jilin University in cardiovascular disease treatment center stay to left ventricular dysfunction as the initial symptom of 117 patients with acute myocardial infarction in patients with clinical data. First, according to the age of the patients into two groups: elderly patients (≥65 years) in 79 cases, non-elderly group (<65 years) 38 cases. One group of men aged 53 cases, 26 females; non-elderly group of 18 males and 20 females. Secondly, according to two groups of hypertension, diabetes and other risk factors and the infarcted area compared to sum up the left ventricular dysfunction as the first symptoms of the clinical features of patients with AMI.Conclusion: 1. to left ventricular dysfunction in patients with AMI as the first symptom common to the elderly and mostly male patients. 2. with left ventricular dysfunction in patients with AMI as the first symptom of hypertension, diabetes and other risk factors more common in patients with and under the influence of many factors, clinical manifestations are not typical, and often painless myocardial infarction, Patients with severe illness and high mortality, its causes of death with age, with or without complications, infarct size, severity of heart failure are closely related. 3. with left ventricular dysfunction in patients with AMI as the first symptom of non-elderly group, ST elevation myocardial infarction segment common type, and its incidence in the non-elderly group, compared the two groups, the difference was statistically significant. The causes of such patients may be associated with chronic progressive multiple arteries atherosclerosis, and the formation of ischemic preconditioning and collateral circulation on the establishment of compensation. Because of age and gender are uncontrollable factors, the regulation of various risk factors for attention, aggressive treatment of hypertension, high blood sugar, etc., reasonable diet, smoking cessation, regular exercise, taking time to do so in patients with primary prevention, secondary prevention Work, so that the incidence of coronary heart disease at the lowest level, especially the elderly, those with atypical symptoms, should arouse our attention in future work. |
