高血压、冠心病和脑卒中是常见、多发的心脑血管疾病。高血压是冠心病及脑卒中的重要危险因素。因此 ,高血压的研究是心血管研究的重中之重。目前认为高血压是由多基因遗传和多个环境因素相互作用的结果[1] 。在多个环境因素中 ,高盐是最常见最重要的环境因素之一。由于高血压 Hypertension, coronary heart disease and stroke are common and frequent cardiovascular and cerebrovascular diseases. Hypertension is an important risk factor for coronary heart disease and stroke. Therefore, the study of hypertension is the most important cardiovascular research. Hypertension is currently thought to result from the interaction of multiple genes and multiple environmental factors [1]. Among many environmental factors, high salt is one of the most common and important environmental factors. Because of high blood pressure
