INTRODUCTION
This study investigated the prevalence of transthoracic echocardiographic abnormalities in patients with ischemic stroke (IS), subarachnoid hemorrhage (SAH), and intracerebral hemorrhage (ICH) in sinus rhythm.
MATERIAL AND METHODS
The patients included 120 with IS, 30 with SAH, and 41 with ICH. All diagnoses were confirmed by magnetic resonance imaging or brain computed tomography. Two-dimensional echocardiograms were taken at the time stroke was diagnosed. All echocardiograms were interpreted by an experienced echocardiographer.
RESULTS
Of 120 IS patients, 1 (1%) had a left ventricular (LV) thrombus, 1 (1%) had mitral valve vegetations, 30 (25%) had LV hypertrophy, 26 (22%) had abnormal LV ejection fraction, 4 (3%) had mitral valve prolapse, 33 (28%) had mitral annular calcium (MAC), 40 (33%) had aortic valve calcium (AVC), 3 (3%) had a bioprosthetic aortic valve, 10 (8%) had aortic stenosis (AS), 6 (5%) had atrial septal aneurysm, 2 (2%) had patent foramen ovale, and 40 (33%) had no abnormalities. Of 30 SAH patients, 5 (17%) had LV hypertrophy, 1 (3%) had abnormal LV ejection fraction, 1 (3%) had AS, 4 (13%) had MAC, 5 (17%) had AVC, and 20 (67%) had no abnormalities. Of 41 ICH patients, 9 (22%) had LVH, 1 (2%) had abnormal LV ejection fraction, 1 (3%) had AS, 6 (15%) had MAC, 8 (20%) had AVC, and 22 (54%) had no abnormalities.
CONCLUSIONS
Transthoracic echocardiographic abnormalities are more prevalent in patients with IS than in patients with SAH or ICH.
介绍
本研究旨在调查窦性心律的缺血性脑卒中（IS）、蛛网膜下腔出血（SAH）和脑出血（ICH）患者经胸超声心动图异常的发生率。
材料与方法
患者包括 120 例 IS 患者、30 例 SAH 患者和 41 例 ICH 患者。所有诊断均通过磁共振成像或脑计算机断层扫描确认。在脑卒中确诊时进行二维超声心动图检查。所有超声心动图均由经验丰富的超声心动图医师解读。
结果
在 120 例 IS 患者中，1 例（1%）有左心室（LV）血栓形成，1 例（1%）有二尖瓣赘生物，30 例（25%）有 LV 肥厚，26 例（22%）有异常的 LV 射血分数，4 例（3%）有二尖瓣脱垂，33 例（28%）有二尖瓣环钙（MAC），40 例（33%）有主动脉瓣钙（AVC），3 例（3%）有生物瓣主动脉瓣，10 例（8%）有主动脉瓣狭窄（AS），6 例（5%）有房间隔瘤，2 例（2%）有卵圆孔未闭，40 例（33%）无异常。30 例 SAH 患者中，5 例（17%）有 LV 肥厚，1 例（3%）有异常 LV 射血分数，1 例（3%）有 AS，4 例（13%）有 MAC，5 例（17%）有 AVC，20 例（67%）无异常。41 例 ICH 患者中，9 例（22%）有 LVH，1 例（2%）有异常 LV 射血分数，1 例（3%）有 AS，6 例（15%）有 MAC，8 例（20%）有 AVC，22 例（54%）无异常。
结论
与 SAH 或 ICH 患者相比，经胸超声心动图异常在 IS 患者中更为常见。
