妈妈79岁，有50年的高血压和15年的肾病，一直吃药控制得还好。 最近时常感到心闷气短，浑身无力。
Exercise/ Treadmill nuclear stress test 结果正常。 Echocardiogram 结果如下。 请教心脏专家， 我们应该担心吗？ 妈妈想要回国治疗。 谢谢大家。
1. Normal left ventricular cavity size, wall thickness, and systolic function. The estimated left ventricular ejection fraction is 60-65%. No regional wall motion abnormalities are detected.
2. Grade 2 diastolic dysfunction is present.
3. Normal right ventricular cavity size and systolic function.
4. Right ventricular systolic pressure is elevated at 38 mmHg, which is mildly elevated pulmonary pressures.
5. The left atrial volume index is severely increased. The interatrial septum is aneurysmal
