In the process of establishing a less invasive assessment strategy for coronary artery disease (CAD) in patients with infrarenal abdominal aortic aneurysm (AAA), the incidence of CAD and the surgical and mid-term outcomes were reviewed. From January 1994 through September 2001, 94 elective surgical repairs of AAA were carried out. Preoperative coronary angiography showed 43 patients (45.7%) had CAD: 29 (67.4%) were asymptomatic, 23 had single-vessel disease (1VD), 12 had 2VD and 8 had 3VD. Of the 43 patients with CAD, 19 (44.2%) underwent coronary interventional therapy before aortic surgery (11 percutaneous transluminal coronary angioplasty (PTCA), 8 coronary artery bypass grafting). Eight asymptomatic patients underwent coronary interventional therapy. None of the patients died of cardiac causes or experienced a postoperative cardiac event. During the follow-up period, 10 late deaths occurred: 7 patients with CAD, and 3 cerebrovascular or cardiac deaths. There was no statistical difference in the survival rate between the groups with and without CAD. Two patients with CAD underwent PTCA during the follow-up period. The findings confirm the need for a less invasive assessment strategy of CAD that does not overlook asymptomatic myocardial ischemia, because the incidence of CAD in patients with AAA is high. 相似文献

INTRODUCTION: Among patients with suspected acute coronary syndromes (ACS) referred for urgent coronary angiography there are some with normal angiograms. AIM: To compare, with respect to angiographic findings, one-year clinical outcomes in patients hospitalised for suspected ACS. METHOD: Between January 2001 and December 2003 emergency angiography was performed in 1169 patients. It revealed no significant coronary lesions in 97 (8.3%) cases, of these 40 being women and 57 men with a mean age of 55+/-15 yrs (Group 1). Sixty consecutive patients with ACS (20 women and 40 men with a mean age of 54+/-9 yrs) and significant coronary artery disease (CAD) confirmed by angiography were the study controls (Group 2). Demographic data, CAD risk factors, angiographic findings, ECG and echocardiographic data as well as laboratory test results were analysed. In a long-term follow-up, the prevalence of recurrent angina and all-cause mortality were assessed. RESULTS: There were no significant differences in patients' demographics between the two groups with the exception of arterial hypertension, which was more frequent in group 1. In group 1 the diagnosis of ACS was established in 14.5% cases, X syndrome in 14.4%, Prinzmetal angina in 4.1%, myocarditis in 6.1% and pulmonary thromboembolization in 5.1%. A definite diagnosis was not related to the cardiovascular disease in 36%. No complications were observed in the late follow-up of group 1 patients. CONCLUSIONS: Apparently normal angiograms are relatively common in patients referred for emergency coronary angiography. In patients without significant CAD on their angiograms the clinical outcome is favourable, without major adverse cardiovascular events in the long-term follow-up. 相似文献

The aim of this study is to investigate the value of hemodynamic changes induced by carotid sinus massage (CSM) on the diagnosis of coronary artery disease (CAD). A total 108 patients (mean age, 54 +/- 10 years, range 33-70) who had no significant stenosis in the carotid artery by duplex ultrasonography (USG) and no history of syncope were included in this study. Carotid sinus massage was performed before coronary angiography with monitoring of electrocardiography and blood pressure. The patients were divided into three groups according to response to CSM: group 1 patients had a decrease in blood pressure or < 10 beats/minute (bpm); group 2 patients had a decrease between 10 and 20 bpm; and group 3 patients had > 20 mm Hg decrease in blood pressure or > 20 bpm. Coronary angiography was performed after CSM in all patients. There was single-vessel disease (VD) in 23 cases, two-VD in 24 cases, and three-VD in 35 cases. Coronary angiography results were normal in 26 cases. The changes in systolic and diastolic blood pressures and heart rate before and after CSM correlated with number of VD. These changes were highest in patients with three-VD, but lowest in patients with normal coronary angiography. The number of diseased vessels and total coronary artery score were lowest in group 1, but highest in group 3. The specificity and sensitivity of CSM-induced > 10 mm Hg in blood pressure (BP) or > 10 bpm changes in heart rate in the diagnosis of CAD were 85% and 71%, respectively. The positive and negative predictive values were 93% and 49%, respectively in the diagnosis of CAD. At the end of this study, we concluded that CSM induced the fall in blood pressure and heart rate and was correlated with number of diseased vessels and the score of coronary artery disease. As dichotomized values, the decrease of > 10 mm Hg in blood pressure and/or > 10 bpm has highest specificity, sensitivity, and positive predictive value in the diagnosis of CAD. 相似文献

BACKGROUND AND AIM: Epidemiological studies have suggested an association between higher body iron stores and coronary artery disease (CAD), but recent trials have reported conflicting data on the role of ferritin in CAD. To assess these findings, we examined the association between serum ferritin and the angiographic extent of coronary atherosclerosis in consecutive patients referred for coronary angiography. METHODS AND RESULTS: We studied 100 consecutive white subjects (41 women and 59 men; mean age 63.7 +/- 11.0 years) who underwent coronary angiography. The data collected at baseline included conventional risk factors for coronary artery disease (CAD), lipid and fasting total homocysteine levels, serum ferritin levels and transferrin saturation, and clinical characteristics. Serum ferritin levels and transferrin saturation (serum iron concentration divided by total iron-binding capacity) were used as measures of the amount of circulating iron available to tissues. Two experienced cardiologists blinded to the clinical and laboratory data reviewed the angiographic cinefilms, and defined the angiographic severity of CAD on the basis of the sum of three vessel scorring systems. The risk of CAD assessed by coronary angiography was not related to ferritin concentrations or transferrin saturation levels. The estimated relative risk of CAD for the fifth vs the first quintile of serum ferritin was 0.83 (95% CI: 0.63-1.24). Forty of the 100 patients had no or minimal CAD (group A; score 0-3), 33 moderate CAD (group B; score 4-8) and 27 severe CAD (group C; score > 8): the serum ferritin levels in the three groups were respectively 165 +/- 126, 167 +/- 121 and 164 +/- 110 ng/ml, and did not represent an independent risk factor for CAD (p = 0.98). Transferrin saturation in the three groups was 22.9 +/- 10%, 21 +/- 9% and 19.9 +/- 10%, with no significant relationship to the severity of CAD (p = 0.23). The presence of angiographic CAD was associated with patient age (p = 0.048), male gender (p < 0.01), high lowdensity lipoprotein cholesterol levels (p = 0.02), low high-density lipoprotein cholesterol levels (p = 0.02), high plasma fibrinogen levels (p < 0.01) and high fasting total homocysteine levels (p = 0.04). CONCLUSION: In patients referred for coronary angiography, higher ferritin concentrations and transferrin saturation levels were not associated with an increased extent of coronary atherosclerosis. 相似文献

Mitral annulus calcification (MAC) is an independent predictor of coronary artery disease (CAD). The present study was designed to determine whether an association exists between MAC and CAD in patients with dilated cardiomyopathy. Among the 286 patients with MAC on echocardiographic examination who underwent coronary angiography, 55 patients with echocardiographic findings of dilated cardiomyopathy (group I) were compared to 60 age-matched controls without MAC and an echocardiographic diagnosis of dilated cardiomyopathy (group II) who underwent coronary angiography during the same time. There were no differences in echocardiographic findings between two groups. The prevalence of CAD was higher in group I when compared to group II (74% vs 28%, p<0.001). With regard to severity of CAD, two-vessel, three-vessel, and left main coronary artery disease were found to be significantly frequent in group I (p<0.001). Multivariate analysis revealed that MAC (p=0.001), diabetes mellitus (p=0.048), and history of anginal chest pain (p=0.009) are the independent predictors for the presence of CAD in patients with dilated cardiomyopathy. In conclusion, MAC may be a marker for the presence of coronary artery disease in patients with dilated cardiomyopathy. 相似文献
