冠状动脉造影与冠心病的临床诊断分析 总被引:1,自引:0,他引:1
目的:观察冠状动脉造影与冠心病的临床诊断符合率。方法:将164例临床诊断为冠心病患者经冠状动脉造影(CAG)与临床进行对比分析。结果:确诊冠心病120例,诊断符合率为73.2%。其中除冠脉痉挛或溶栓成功或自溶8例,X综合征5例。尚有44例误诊,占26.8%,主要是高血压性心脏病、心肌病、心律失常等。结论:严格掌握心胶痛标准是冠心病诊断正确的关键。 相似文献

Provocative tests for coronary spasm were performed in a groupof 131 patients (124 men and 7 women) with recent (<6 weeks)transmural myocardial infarction. Coronary arteriography wasperformed 27±9 days after the onset of the infarction.The provocative test was performed using a single IV bolus of0.4 mg of ergometrine. Aortic pressure, ECG and arteriogramsof the two coronary vessels were repeated 3 and 5 min later.Provoked spasm was observed in 27 (21%) of the patients. In13 (48%) the coronary spasm occurred in a vessel presumed tobe responsible for the myocardial infarction, while it was observedin coronary artery unrelated to the area of the infarct in 14(52% of the cases with spasm). Thus, this study demonstratesa high degree of reactivity of the coronary tree of patientswith recent transmural myocardial infarction suggesting thelikelihood of a role for spasm in the infarction process andoffering some explanation for subsequent recurrent ischemicevents. 相似文献

Summary A patient with migraine headaches of the cluster variant type is presented in whom vasospasm of the middle cerebral artery, the anterior cerebral artery and the internal carotid artery triggered a pain episode identical in character and severity to the headaches which had led to her investigation. Vasospasm associated with the painful phase of headache in this case conflicts with the more accepted theory that the pain phase of a vascular headache is related to vasodilatation of cerebral or extracerebral vessels. The literature is reviewed. 相似文献

We combined edrophonium provocative testing with the technique of radionuclide oesophageal transit (RET) in 30 consecutive patients with non-cardiac chest pain (NCCP) and 12 controls. The oesophageal transit time of aqueous technetium-99m sulfur colloid was determined before and after intravenous infusion of 80 g/kg edrophonium chloride (ED). Patient symptoms during provocative RET (P-RET) were recorded. Thirteen (43%) of the patients had abnormal study results, whereas all control subjects had normal results. Three groups considered abnormal were observed: (a) in two patients (6%), the pain was reproduced and transit pre- and post-ED administration was prolonged (>15 s); (b) in six patients (20%), the pain was reproduced, but transit was normal pre- and post-ED; (c) in five patients (17%), transit pre- and post-ED was prolonged, but no pain was reproduced. In five patients (17%), ED prolonged the transit time > 15 s without pain, but the baseline transit was normal. Transit time was measurable in 23 patients. Mean pre-ED transit time was 10.2 ± 7.4 s (mean ± SD) and post-ED, 12.4 ± 8.0 s (P=0.3). We conclude that ED has no significant effect on transit time, and the pain induced by ED rarely correlates with an abnormal transit; P-RET provides additional information to baseline RET, increasing sensitivity, and may be a useful screening method in the evaluation of patients with NCCP. 相似文献

Four-hundred fifty-eight patients with cancer of the oesophagus were subjected to revisional laparotomy. Metastases into subphrenic lymph nodes were registered in 24% of the cases with a tumor in the bronchial segment; 42% with tumor in the subbronchial segment; 48% with tumor in the retropericardial segment; 71% with tumors in the sub-, intra-, and supraphrenic segments of the oesophagus. In 345 cases, laparotomy was followed by tube gastrostomy (Beck—Carrel method) with two operative deaths. Fifty-six patients in good condition with a small tumor in the middle part of the oesophagus (≤5 cm) without any abdominal metastases were subjected to primary oesophagoplasty: a 30–32-cm tube was formed out of the greater curvature of the stomach and placed retrosternally; gastrostomy was performed on the level of the thyroid cartilage (without any operative deaths). In two weeks, extirpation of the thoracic part of the oesophagus (with preoperative irradiation) was performed on patients with no abdominal metastases. Then the patients with primary oesophagoplasty were subjected to oesophago-gastrostomy of the neck. From six to 12 months following the combined treatment, the gastrostomy tube of 45 patients was lengthened to 30–32 cm and used for retrosternal oesophagoplasty (six operative deaths). Oesophagoplasty was performed on 14 patients during the extirpation of the oesophagus (six operative deaths). 相似文献

Oesophageal duplications are rare congenital abnormalities. Most of them do not communicate with the oesophageal lumen. We present a very uncommon finding of communicating oesophageal duplication in which the connection between the oesophagus and its duplicate portion was demonstrated by CT. 相似文献
