急性冠状动脉综合征致病危险因素分析 总被引:16,自引:2,他引:16
目的:探讨急性冠状动脉综合征中致病危险因素的变化情况及其意义。方法:对107例行冠脉造影的急性冠脉综合征(急性心肌梗死及不稳定型心绞痛)与其它类型冠心病的血管阻塞积分进行计算,将其血糖、血脂等进行比较。结果:急性冠脉综合征患者中有高血压、冠心病、糖尿病家族史和(或)伴高血压、糖尿病者48例(62.3%)。其C反应蛋白(CRP)、血糖、血脂紊乱情况均较其它型冠心病更为明显。在急性心肌梗死与冠心病组中,血管阻塞积分与年龄明显相关。在急性心肌梗死组中,吸烟者的发病年龄与HDL明显低于不吸烟者,而红细胞压积则明显高于不吸烟者。结论:急性冠脉综合征的发生与遗传、吸烟、血糖、血脂代谢以及CRP的异常等因素参与有关。 相似文献

Clark LT 《The Medical clinics of North America》2005,89(5):977-1001, 994
Cardiovascular disease (in particular, CHD) is the leading cause of death in the United States for Americans of both sexes and of all racial and ethnic backgrounds. African Americans have the highest overall CHD mortality rate and the highest out-of-hospital coronary death rate of any ethnic group in the United States, particularly at younger ages. Contributors to the earlier onset of CHD and excess CHD deaths among African Americans include a high prevalence of coronary risk factors, patient delays in seeking medical care, and disparities in health care. The clinical spectrum of acute and chronic CHD in African Americans is the same as in whites; however, African Americans have a higher risk of sudden cardiac death and present clinically more often with unstable angina and non-ST-segment elevation myocardial infarction than whites. Although generally not difficult, the accurate diagnosis and risk assessment for CHD in African Americans may at times present special challenges. The high prevalence of hypertension and type 2 diabetes mellitus may contribute to discordance between symptomatology and the severity of coronary artery disease, and some noninvasive tests appear to have a lower predictive value for disease. The high prevalence of modifiable risk factors provides great opportunities for the prevention of CHD in African Americans. Patients at high risk should be targeted for intensive risk reduction measures, early recognition/diagnosis of ischemic syndromes, and appropriate referral for coronary interventions and cardiac surgical procedures. African Americans who have ACSs receive less aggressive treatment than their white counterparts but they should not. Use of evidence-based therapies for management of patients who have ACSs and better understanding of various available treatment strategies are of utmost importance. Reducing and ultimately eliminating disparities in cardiovascular care and outcomes require comprehensive programs of education and advocacy(Box 4) with the goals of (1) increasing provider and public awareness of the disparities in treatment; (2) decreasing patient delays in seeking medical care for acute myocardial infarction and other cardiac disorders; (3) more timely and appropriate therapy for ACSs; (4) improved access to preventive, diagnostic, and interventional cardiovascular therapies; (5) more effective implementation of evidence-based treatment guidelines; and (6) improved physician-patient communications. 相似文献

Using standard methods of the epidemiological survey the authors examined a 10% randomized sample of men aged 40 to 59 years living in a rural area. A total of 533 persons were entered into the study (a 82% coverage). Based on the epidemiological data the coronary heart disease (CHD) prevalence was established to amount to 8.8% according to the enlarged criteria (angina pectoris of effort according to the WHO cardiological questionnaire; the definite myocardial infarction with the Minnesota code categories 1.1-1,2.7; the painless pattern of CHD with categories 4.1-4.2 and 5.1-5.2 without 3.1 and 3.3; possible myocardial infarction 1.2.8, 1.3; possible myocardial ischemia 4.3, 5.3; the arrhythmic pattern 6.1, 7.1, 8.3; myocardial ischemia with left ventricle hypertrophy 4.1-4.2, 5.1-5.2 with 3.1, 3.3; possible myocardial infarction in the anamnesis in accordance with the WHO cardiological questionnaire). It was also found that in persons aged 50 to 59 years, CHD occurs 2 times as frequently as in those aged 40 to 49 years (13.1 and 5.8%, respectively). The prevalence of CHD was discovered to be about 3.5 times higher in the presence of arterial hypertension and overweight and 2 to 2.5 times higher in the presence of hypercholesterolemia, hypo-alpha-cholesterolemia and hypertriglyceridemia. A high correlation was noted between arterial hypertension and overweight and the prevalence of CHD before (r = 0.174 and r = 0.198, respectively) and after elimination of risk factors (r = 0.14 and r = 0.14). Among CHD patients, one risk factor was noted in 21.8%, two in 39.1%, three and more in 23.9%, whereas among persons without CHD in 32.4, 10.9 and 3.5%, respectively. 相似文献

AIM: To study correlations between coronary heart disease (CHD) and psychosocial risk factors. MATERIAL AND METHODS: CHD affected more frequently workers engaged in hard physical labour, in poorly educated persons; the least CHD morbidity was recorded in managers and highly educated persons. CHD males think of their health much worse than males free of CHD. The former smoked much more before CHD diagnosis, but when CHD comes they quit and reduce smoking much more frequently. This fact explains why smokers are encountered among CHD patients two times less frequently than in CHD-free males. In spite of stronger motivation for adequate diet, CHD males changed their nutrition pattern only in 3.7%. CHD males sleep worse: good sleep was registered in CHD-free males two times more frequently. Psychological risk factors such as personal anxiety, sleep disorders were reported much more frequently in CHD patients proving the fact of social stress involvement in development of CHD. So-called coronary behavior was observed in both groups of males with the same rate. Thus, the coronary behavior is not associated with CHD. CONCLUSION: Development of CHD is associated not with the behavior but its components (depression, anxiety, etc.). 相似文献

BACKGROUNDCoronary heart disease (CHD) is a type of coronary atherosclerotic heart disease. In recent years, the incidence of CHD has been increasing annually, with an increasing number of young patients. Severe CHD may cause severe myocardial ischemia or myocardial necrosis, which in turn may cause myocardial infarction and related complications that seriously affect the life and health of the patient.AIMTo examine the coronary arteries and clinical features of young and middle-aged male patients with CHD.METHODSFrom February 2019 to January 2020, 110 male CHD patients admitted to our hospital were selected as research subjects and were divided into two groups by age: middle-aged group (n = 55) and young group (n = 55). The coronary arteries and clinical features of the patients were compared.RESULTSThere were no significant differences in dyslipidemia, stroke history, high-density lipoprotein cholesterol, or triacylglycerol (P > 0.05) between the two groups. In the young group, age, diabetes, hypertension, smoking history, body mass index, family history of CHD, drinking history, fibrinogen, low-density lipoprotein cholesterol, total cholesterol, and single-vessel disease were higher than those in the middle-aged group. Correspondingly, serum uric acid, hyperuricemia, myocardial infarction, Gensini score > 50, collateral circulation, multivessel disease, double vessel disease, involvement of the right coronary artery, and involvement of the left main coronary artery were lower in the young group than in the middle-aged group. The middle-aged group mainly suffered from a high Gensini score, implicating multiple arteries, whereas the young group was mainly affected by single-vessel disease. The between-group difference was significant (P < 0.05).CONCLUSIONIn CHD attacks, multiple coronary arteries are implicated in middle-aged male patients and single-vessel disease in young male patients. 相似文献

OBJECTIVE--To determine coronary heart disease (CHD) incidence among dyslipidemic subjects with non-insulin-dependent diabetes mellitus (NIDDM) and to assess the effect of lipid-modifying treatment on serum and lipoprotein lipids and the CHD incidence in these patients. RESEARCH DESIGN AND METHODS--Of the 4081 men participating in the Helsinki Heart Study, a coronary primary prevention trial with gemfibrozil in middle-aged men with high non-high-density lipoprotein (HDL) cholesterol (greater than 5.2 mM; 200 mg/dL), 135 had NIDDM at entry. The incidence of definite myocardial infarction and cardiac death and changes in serum and lipoprotein lipids were determined during the 5-yr trial in the NIDDM patients and compared with those observed in nondiabetic trial participants. RESULTS--Compared with nondiabetic subjects, NIDDM patients had lower HDL cholesterol (P less than 0.001), higher triglyceride concentration (P less than 0.0001), and greater body mass index (P less than 0.001), there were more hypertensive patients (P less than 0.001) among them. The incidence of myocardial infarction and cardiac death was significantly higher among diabetic than nondiabetic participants (7.4 vs. 3.3%, respectively, P less than 0.02). CHD incidence in the gemfibrozil-treated diabetic men (n = 59) was 3.4% compared with 10.5% in the placebo group (NS). In multivariate analysis, diabetes (P less than 0.05), age (P less than 0.0001), smoking (P less than 0.0001), low HDL cholesterol (P less than 0.05), and high low-density lipoprotein cholesterol (P less than 0.005) were independently related to CHD incidence. Gemfibrozil-induced serum and lipoprotein lipid changes in diabetic patients were similar to those observed in nondiabetic subjects. CONCLUSIONS--Compared with similarly dyslipidemic nondiabetic subjects, patients with NIDDM are at markedly increased risk of CHD. This elevated risk can be somewhat reduced by gemfibrozil. 相似文献

Coronary heart disease (CHD) remains the leading cause of mortality for US women, responsible for almost 250,000 deaths annually. Preventive heart-health behavioral changes by women and aggressive coronary risk reduction can decrease the number of women disabled and killed by CHD. Angina is the predominant initial and subsequent presentation of CHD in women; categorization of chest pain and risk stratification of women assume pivotal roles. A robust evidence-based algorithm can guide cardiovascular imaging techniques to evaluate women with suspected myocardial ischemia to detect those with worsened survival. Restricted functional capacity (<5 METs) is a consistent marker of worsened prognosis. Younger women have substantially higher mortality rates than men following myocardial infarction and coronary bypass surgery. Although these women have more comorbidity and risk factors, other issues including biological differences, treatment differences, and psychosocial factors require management strategies tailored to the unique needs of women. 相似文献

Coronary heart disease risk equivalence in diabetes depends on concomitant risk factors 总被引:10,自引:0,他引:10
Howard BV Best LG Galloway JM Howard WJ Jones K Lee ET Ratner RE Resnick HE Devereux RB 《Diabetes care》2006,29(2):391-397
OBJECTIVE: Diabetes has been defined as a coronary heart disease (CHD) risk equivalent, and more aggressive treatment goals have been proposed for diabetic patients. RESEARCH DESIGN AND METHODS: We studied the influence of single and multiple risk factors on the 10-year cumulative incidence of fatal and nonfatal CHD and cardiovascular disease (CVD) in diabetic and nondiabetic men and women, with and without baseline CHD or CVD, in a population (n = 4,549) with a high prevalence of diabetes. RESULTS: In both sexes, diabetes increased the risk for CHD (hazard ratio 1.99 and 2.93 for men and women, respectively). Diabetic men and women had a 10-year cumulative incidence of CHD of 25.9 and 19.1%, respectively, compared with 57.4 and 58.4% for nondiabetic men and women with previous CHD. The pattern was similar when only fatal events were considered. Diabetic individuals with one or two risk factors had a 10-year cumulative incidence of CHD that was only 1.4 times higher than that of nondiabetic individuals (14%). However, the 10-year incidence of CHD in diabetic subjects with multiple risk factors was >40%, and the incidence of fatal CHD was higher in these subjects than in nondiabetic subjects with previous CHD. Data for CVD showed similar patterns, as did separate analyses by sex. CONCLUSIONS: Our results and comparisons with other available data show wide variation in the rate of CHD in diabetes, depending on the population and existing risk factors. Most individuals had a 10-year cumulative incidence >20%, but only those with multiple risk factors had a 10-year cumulative incidence that was equivalent to that of patients with CHD. Until more data are available, it may be prudent to consider targets based on the entire risk factor profile rather than just the presence of diabetes. 相似文献

Coronary heart disease incidence and cardiovascular mortality in Busselton with reference to glucose and insulin concentrations 总被引:14,自引:0,他引:14
In the 1966 study of the population of Busselton, Australia, blood sugar and serum insulin levels were measured one hour after an oral glucose load, in addition to the conventional cardiovascular risk factors. The six-year incidence of coronary heart disease (CHD) and the 12-yr mortality from CHD and from all cardiovascular diseases is described in relation to the initial baseline variables measured using the upper 20th percentile values (age-specific and sex-specific) to define the risk ratios. In younger subjects (ages less than 60 yr), elevated blood pressure levels for both sexes (risk ratios from 2.9 to 5.2) and elevated serum cholesterol concentrations for males (risk ratios from 3.0 to 3.3) were strong predictors of cardiovascular risk. In men aged 60 to 69 yr, those with upper range one-hour serum insulin concentrations showed marked associations with the six-year incidence of CHD, the 12-yr mortality from CHD, and the 12-yr mortality from all cardiovascular diseases (risk ratios were 2.0, 2.3, and 2.4, respectively). The relationship of elevated serum insulin and cardiovascular mortality persisted when males of all ages were analyzed, and it appeared to be independent of the other major risk factors. In females, no association between serum insulin and CHD or cardiovascular disease could be found. Although the age and sex specific upper 20th percentile values for one-hour blood sugar concentrations showed a low grade association in patients with subsequent cardiovascular disease end points, more noticeable risk ratios were demonstrated at the higher blood sugar level of 200 mg/100 ml or greater (in the age group 60 yr and over, risk ratios were 2.2 in males and 2.6 in females. 相似文献

Patients with diabetes without a prior myocardial infarction are at a similar risk of coronary heart disease (CHD) events as non-diabetic subjects with a prior myocardial infarction. Furthermore, prognosis after the first myocardial infarction is worse in diabetic compared to non-diabetic patients. Therefore, management of cardiovascular risk factors in subjects with diabetes should be as vigorous as in patients with known CHD who have had a myocardial infarction. Randomised controlled trials have shown that efficacy of cholesterol lowering and antihypertensive therapy in type 2 diabetes is at least as effective as in non-diabetic subjects in preventing macrovascular disease. Antiplatelet therapy with aspirin reduces the risk of CHD events in high-risk patients and the benefit is similar in subjects with and without diabetes. Improved glycaemic control has a modest beneficial effect on CHD risk. There is residual excess risk of CHD in type 2 diabetes, which is not explained by traditional cardiovascular risk factors. Insulin resistance may partly mediate this. Prediabetic subjects who are insulin resistant have more adverse levels of triglycerides, high density lipoprotein (HDL)-cholesterol and blood pressure than those who are insulin sensitive. Moreover, factors associated with insulin resistance are significant predictors of CHD events in subjects with diabetes, in addition to conventional risk factors. The thiazolidinedione, pioglitazone, improves glycaemia and insulin sensitivity in hyperglycaemic patients. It also improves insulin and triglyceride levels and lowers blood pressure. Thiazolidinediones have been found to have vasculo-protective effects in both acute and chronic vascular injury in animal models. For prevention of CHD in type 2 diabetes a multi-factorial approach should be considered, including improved glycaemic control, aggressive management of dyslipidaemia and hypertension, anti-platelet therapy, reduction of insulin resistance and use of agents that improve insulin sensitivity. 相似文献
