Abstract/OtherAbstract:
|
The devastating long-term consequences of high blood pressure include stroke, heart disease, atherosclerosis, renal disease, and other end-organ damage. From a physiologic perspective, it is not apparent why the propensity for hypertension is so widespread in the general population. Clearly, an adequate arterial pressure is essential for perfusion of the tissues to provide adequate oxygenation and nutrition to the brain and other critical organs. Although the various microcirculatory beds have the capability to adjust vascular resistance to autoregulate blood flow, systemic arterial pressure is usually maintained at levels greater than required for requisite tissue perfusion. The myriad of neurohumoral mechanisms designed to protect against decreases in systemic arterial pressure provide a reserve capacity for increased perfusion when there are increased tissue demands. The unfortunate consequence of having these powerful physiologic control mechanisms is that they may be inappropriately activated in certain circumstances or by genetically determined traits, leading to hypertension and cardiovascular injury. Evidence continues to accumulate indicating that the kidney not only is victim to hypertension-related injury, but also contributes as a villain to the hypertensinogenic process. |
