摘要
Doppler echocardiography 是为对心脏舒张的机能障碍的评价的标准答案，它逐渐地作为心失败的一个原因被认出，在特别老。用 Doppler echocardiography 技术的联合，识别心脏舒张的机能障碍的等级是可能的，估计左室的充满压力并且建立心脏舒张的机能障碍的慢性。这些导出 physiologically 的措施广泛地对左心压力的侵略大小被验证了并且被显示了在大量临床的背景预示地珍贵。这评论探索机制，并且来临到对心脏舒张的机能障碍的评价在老。为临床医生的挑战是从与正常变老联系的那些识别 pathophysiological 变化。当在联合，和花的很长时间使用了进报道时， Doppler echocardiographic 参数在对在更老的病人的 dyspnoea 的评价是有用的并且提供预示的卓见。
Doppler echocardiography is the gold standard for assessment of diastolic dysfunction, which is increasingly recognised as a cause of heart failure, especially in the elderly. Using a combination of Doppler echocardiography techniques, it is possible to identify grades of dia- stolic dysftmction, estimate left ventricular filling pressures and establish the chronicity of diastolic dysfunction. These physiologi- cally-derived measures have been widely validated against invasive measurements of left heart pressures and have been shown to be prog- nostically valuable in a wide range of clinical settings. This review explores the mechanisms, and approaches to the assessment of diastolic dysfunction in the elderly. The challenge for clinicians is to identify pathophysiological changes from those associated with normal ageing. When used in combination, and taking age into account, Doppler echocardiographic parameters are helpful in the assessment of dyspnoea in older patients and provide prognostic insights.
