THE CARDIAC CONSEQUENCES OF HEMISPHERIC STROKE

截至1998年1月16日，我们已经招募了138名中风患者和TIA 患者进入研究。已经对616名患者进行了纳入评估， 这意味着包含频率为23%。的主要原因是 拒绝参加这项研究是因为一方缺乏兴趣 患者或亲属或提前出院 才能进行评估。后者通常意味着 患者由主治医生出院，而不是 入院后24小时内进行脑血管计划。被录取的 患者通常代表那些没有参加 学习。参加这项研究的非洲裔美国人比白人多 个人，代表巴尔的摩地区的种族分布。 招募了同等数量的男性和女性患者，他们曾经 再一次代表未登记的团体。和以前一样， 未被纳入研究的主要原因是重要的 闭塞、重大伴发疾病和放射学证据 上一次中风的。这项研究中包括的大多数患者 遭受了半球脑梗塞。大约7%的患者有 半球脑干出血。这与 一般人群中脑出血的发病率。这个 中风的分布和性质在包括在内的患者中相似 参加研究的人和没有参加研究的人，再次强调 被研究人群代表了一般人群 入院的中风患者。左半球和右半球 和脑干中风一样，没有偏侧性。 占优势。中风在这些患者中的分布是相似的 没有参加研究的人与参加研究的人相比， 再次强调不带偏见。几乎100%的患者 接受心脏自主神经测试、Holter磁带评估和晚期 潜力分析。经食道超声心动图检查 76%的患者在研究中，但在24%的患者中没有执行，或者是因为 这被病人拒绝了，或者被认为是禁忌 或因为这些患者最近有过一次 经食道超声心动图。腺苷铊扫描是 在近60%的患者中进行了治疗。在这些患者中， 没有做过手术，有记录的冠状动脉病史 疾病。约30%的患者没有参加随访 评估。

As of January 16, 1998, we have recruited 138 stroke patients and TIA patients into the study. 616 patients have been assessed for inclusion, representing an inclusion frequency of 23%. The principle reason for refusal to participate in the study was a lack of interest on the part of the patient or relatives or a premature discharge from hospital before assessment could take place. This latter usually meant that patients were discharged by attending physicians other than those in the Cerebrovascular Program within 24 hours of admission. The enrolled patients are generally representative of those not enrolled in the study. More african americans were enrolled in the study than white individuals, representing the racial distribution in the Baltimore area. An equal number of male and female patients were recruited, which once again is representative of the nonenrolled group. As before, the principle reasons for non-enrollment in the study are significant obtundation, significant concomitant disease and radiological evidence of previous stroke. The majority of patients included in this study suffered a hemispheric infarct. Approximately 7% of patients had a hemispherical brain stem hemorrhage. This is consistent with the incidence of cerebral hemorrhage in the general population. The distribution and nature of strokes is similar in the patients included in the study and those not enrolled in the study, once again emphasizing that the study population is representative of the general population of stroke patients admitted to the hospital. Left and right hemispheric and brain stem strokes are equally represented without laterality predominance. The distribution of stroke is similar in those patients not enrolled in the study as compared to those enrolled in the study, once again emphasizing the lack of bias. Nearly 100% of patients underwent cardiac autonomic testing, Holter tape assessment and late potential analysis. Transesophageal echocardiography was performed in 76% of patients in the study, but not performed in 24%, either because this was refused by the patient or was considered to be contraindicated by the cardiology staff, or because these patients had had a recent transesophageal echocardiogram. Adenosine thallium scanning was performed in nearly 60% of the patients. In those patients in whom it was not performed, there was a documented history of coronary artery disease. Approximately 30% of patients did not attend a follow-up assessment.
