左房增大常见于高血压心脏病,决定左房大小主要因素是左室功能障碍,是左室舒张障碍的重要指标。左房大小主要用心脏彩超测定,有两个指标:左房内径(LAD)和左房容积(LAV)。目前很多临床研究发现左房大小与心血管事件发生相关,是预测心血管事件 Left atrial enlargement common in hypertensive heart disease, the main factor determining left atrial size is left ventricular dysfunction, is an important indicator of left ventricular diastolic dysfunction. The size of the left atrium was mainly determined by echocardiography. There were two indexes: left atrium diameter (LAD) and left atrium volume (LAV). At present, many clinical studies have found that left atrial size and cardiovascular events related to the prediction of cardiovascular events
