Two-dimensional echocardiograms were done during rest and after exercise in 95 patients who subsequently had coronary arteriography. Prior myocardial infarction was present in 36 patients, 35 of whom had wall motion abnormalities. There was no evidence of prior infarction in 59 patients, 44 of whom had coronary disease. In these 44 patients, the exercise electrocardiogram showed ischemia in 19, was normal in 13, and was nondiagnostic in 12. Exercise echocardiograms were abnormal in 35 of these 44 patients. In 15 patients without coronary disease, the treadmill response was nondiagnostic in 6, ischemic in 1, and normal in 8. Exercise echocardiograms were normal in 13 of these 15 patients. We conclude that exercise echocardiography is a valuable addition to routine treadmill testing. It may be of special value in patients with an abnormal resting electrocardiogram or a nondiagnostic response to treadmill testing or when a false-negative treadmill test is suspected. 相似文献

Distribution of left ventricular (LV) hypertrophy was assessed by wide-angle, 2-dimensional (2-D) echocardiography in 153 patients with hypertrophic cardiomyopathy and compared with the scalar electrocardiogram in the same patients. The most common electrocardiographic alterations were S-T segment changes and T-wave inversion (61%), LV hypertrophy (47%), abnormal Q waves (25%), and left atrial enlargement (24%). LV hypertrophy on the electrocardiogram was significantly more common in patients with the most extensive distribution of LV hypertrophy on 2-D echocardiogram involving substantial portions of both the ventricular septum and LV free wall (type III; 51 of 69, 74%) than in those with more limited distribution of LV hypertrophy (21 of 84, 25%; p less than 0.001). Most patients with hypertrophic cardiomyopathy and normal electrocardiograms (13 of 23) had localized (type I) hypertrophy, but only 4 had the extensive type III pattern of hypertrophy. Abnormal Q waves were significantly more common in those patients without hypertrophy of the anterior, basal septum (type IV; 15 of 27, 56%) than in those with basal septal hypertrophy (23 of 126, 18%; p less than 0.001); abnormal Q waves were uncommon in extensive type III distribution of hypertrophy (13 of 69, 19%). Thus, although no single electrocardiographic abnormality is characteristic of hypertrophic cardiomyopathy, 2-D echocardiography clarifies the significance of certain electrocardiographic patterns: (1) LV hypertrophy on the electrocardiogram, although present in only about half of the study group, was a relatively sensitive (74%) marker for extensive (type III) LV hypertrophy; (2) abnormal Q waves cannot be explained by ventricular septal hypertrophy alone; and (3) a normal electrocardiogram was most commonly a manifestation of localized LV hypertrophy. 相似文献

The charts of 238 patients with systemic lupus erythematosus (SLE) were reviewed. Although not routinely screened for biochemical evidence of liver disease, 124 of 206 patients tested had at least one abnormal result, and 43 met strict criteria for the existence of liver disease. In most patients, a specific viral or drug etiology could not be implicated. The spectrum of liver disease in 33 patients from whom liver tissue was available included cirrhosis, chronic active hepatitis, granulomatous hepatitis, chronic persistent hepatitis and steatosis. Three of four cirrhotic patients demonstrated a peculiar form of cholestasis which resembled a “canalicular cast” of bile. Of the nine patients who had serial liver biopsies, four showed progression of their disease. Three patients died of liver failure. Liver involvement in SLE is more common than previously recognized. Severe and even fatal liver disease can occur. 相似文献

Summary: Specific serological tests which are now available for the diagnosis of infection with hepatitis A and hepatitis B viruses, were used to distinguish viral hepatitis from other causes of liver disease in pregnancy. Forty-nine (51·6%) of 95 pregnant patients had viral hepatitis, 24 hepatitis A and 25 hepatitis B. The majority of patients (26 of 28) presenting before 22 weeks gestation had viral hepatitis. By contrast, 23 (34·3%) of the remaining 67 patients presenting with abnormal liver function tests at ≫ 22 weeks gestation, had viral hepatitis; the majority of the remainder had features compatible with intrahepatic cholestasis of pregnancy. Although there were significant clinical and biochemical differences between the two groups, accurate diagnosis was only possible by using specific virological tests. 相似文献

Serum and urinary neopterin levels were measured by radioimmunoassay in 120 healthy controls, 16 asymptomatic HBsAg carriers, 12 patients with acute hepatitis, 13 with chronic inactive hepatitis, 35 with chronic active hepatitis, 46 with liver cirrhosis, 18 with hepatocellular carcinoma, and 6 with alcoholic liver disease. Serum and urinary neopterin levels were significantly higher in almost all patients than in normal subjects. Neopterin levels were highest in acute hepatitis and correlated with the results of liver function tests, but did not show this correlation in chronic liver disease. In chronic liver disease, the levels of serum neopterin in non-A non-B viral patients was significantly increased, compared with those in B viral and alcoholic patients. The rate of abnormal urinary neopterin levels in chronic liver disease was higher than the rate of abnormal serum neopterin levels, but no difference was observed between the rates of abnormal serum and urinary levels in acute hepatitis and asymptomatic HBsAg carriers. These results indicate that serum and urinary neopterin levels may be useful markers for cell-mediated immunity in liver disease, and that the immune system response in chronic liver disease may be different for different pathogens. 相似文献

A consecutive series of 86 patients with an inverted T wave showing terminal positivity (overshoot) of a specific pattern in the resting electrocardiogram were studied. Patients with bundle branch block or electrocardiographic evidence of acute infarction and those taking digoxin or a similar drug were excluded. In 67 patients the heart was examined by echocardiography and in a further two by direct inspection. Sixty six of the 69 patients had an abnormal thickness of the left (or right) ventricle or a calculated left ventricular mass greater than 200 g. Seven of the patients examined by echocardiography had clinically pure ischaemic heart disease; all showed evidence of left ventricular enlargement. In only 39 of the 63 patients with anatomical evidence of left ventricular hypertrophy or dilatation did the electrocardiogram satisfy the standard voltage criterion of left ventricular hypertrophy. In the absence of acute infarction, bundle branch block, or digitalisation positive T wave overshoot of the pattern described is a sign of increased ventricular mass. 相似文献

BACKGROUND: Patients with left bundle branch block exhibit abnormal septal motion which may limit the interpretation of stress echocardiograms. This study sought to assess the diagnostic value of dobutamine-atropine stress echocardiography in left bundle branch block patients. METHODS AND RESULTS: Sixty-four left bundle branch block patients (mean age 59 years, 24 men) with suspected coronary artery disease underwent dobutamine-atropine stress echocardiography and coronary arteriography. Myocardial ischaemia was defined as new or worsening wall thickening abnormalities. Coronary artery disease was quantitatively defined as a diameter stenosis >/=50% in a major epicardial artery. Rest septal motion was normal (apart from the early systolic septal notch) in 34 patients (53%) and abnormal in 30 patients (47%). Rest septal thickening was normal in 32 patients (50%) and abnormal in 32 patients (50%). All seven patients with a QRS duration >/=160 ms and an abnormal QRS axis had abnormal rest septal motion and thickening. Inter-observer agreement for ischaemia was 88%. In all but one patient disagreement was in the septum. For the anterior and posterior circulation, respectively, sensitivity was 60% (9/15) and 67% (8/12), specificity was 94% (46/49) and 98% (51/52), and accuracy was 86% (55/64) and 92% (59/64). Sensitivity for the anterior circulation tended to be better in patients with normal rest septal thickening (83% vs 44%). CONCLUSIONS: Dobutamine-atropine stress echocardiography has excellent diagnostic specificity in left bundle branch block patients with suspected coronary artery disease. In patients with abnormal rest septal thickening, however, dobutamine-atropine stress echocardiography may lack good sensitivity for detection of coronary artery disease in the anterior circulation. Left bundle branch block patients who potentially most benefit from dobutamine-atropine stress echocardiography may initially be selected by their resting electrocardiogram. 相似文献

OBJECTIVE--To investigate interrelations between ventricular long axis function, resting electrocardiogram, and myocardial perfusion imaging in a group of patients with syndrome X in order to define possible underlying mechanisms. DESIGN--Prospective echocardiographic, electrocardiographic, and myocardial perfusion imaging. SETTING--A tertiary referral centre for cardiac diseases with invasive and non-invasive facilities. PATIENTS--50 consecutive patients with syndrome X selected on the basis of a history of angina, ST segment depression on exercise, and normal coronary arteriograms and 21 controls of similar age. RESULTS--Long axis motion of one or both ventricles assessed by echocardiography was abnormal in 37 patients. The onset of systolic shortening was delayed by > 130 ms (upper limit of normal 95% confidence interval) in eight patients, and was associated with prolonged shortening during the isovolumic relaxation period in seven (p < 0.01) (systolic abnormalities). The onset of diastolic lengthening was delayed by > 80 ms in 20. Early diastolic peak lengthening rate was < 4.5 cm.s-1 in 13 patients, and the relative amplitude of lengthening during atrial systole was > 45% in 18. On the resting electrocardiogram septal q waves were absent in 12 patients. This was associated with long axis systolic disturbances in seven patients (p < 0.05). T waves were abnormal in 10 and associated with delayed onset of early diastolic lengthening in all (p < 0.001). Late diastolic long axis disturbances were not associated with any consistent electrocardiographic abnormality. Myocardial perfusion imaging was abnormal in six of 33 patients, four of whom had systolic abnormalities (p < 0.03). Imaging was normal in the rest, but in 13 of them long axis function was abnormal in the left side and in four it was abnormal on the right ventricle. Both electrocardiography and imaging were normal in 10 patients. No patient with an abnormal electrocardiogram or myocardial perfusion had normal long axis motion on echocardiography. CONCLUSION--The function of the left and right ventricular long axes was abnormal in about 70% of a sample of patients with syndrome X. Systolic disturbances were consistently associated with absent septal q wave and abnormal myocardial perfusion imaging, while early diastolic disturbances correlated with T wave abnormalities. These associations suggest that the three different investigations detect related objective abnormalities in one or more subgroups of patients with syndrome X. 相似文献
