The elevated arterial pressure of chronic hypertension (HT) is caused by increased total peripheral vascular resistance (TPVR). Hemodynamically, therefore, HT is the result of vascular change. The primary goal of the present presentation is to delineate the current status and recent advances that characterize this vascular change responsible for the HT development. As background knowledge for understanding the nature of the change, it is informative to inquire into the cause of the change. Something must happen to one or more of the controlling systems that normally regulate vascular resistance. These systems include (1) the autonomic nervous system which expresses activity of neurogenic afferents and of the central nervous system;(2) the kidney with two relevant functions (a) salt and water metabolism, and (b) production of regulatory hormones with either pressor or depressor actions; and (3) the adrenal cortex. These neurogenic and humoral factors, along with appropriate genetic matrix and environmental influences, such as sodium intake, affect the resistance vessels in such a way that TPVR is increased. It is usually difficult to identify the" prime mover" that initiates the overall process. This is true of the most common types of the disease, clinical essential HT and experimental spontaneous HT in the rat. However, even when the initiating factor is known, such as renal ischemia or mineralocorticoid excess, the sequence of events leading from this
