Review Of Literature On Hypertension
While it is true that science has afforded society different medications as a method of treatment for hypertension, the reality is that there are engendered problems with drug therapies; allergies, increased risk factors, non-compliance, etc.
Because drug therapies are not always effective, researchers have begun looking more closely at hypertension and its root causes to determine, what if any, non-medicinal treatments can be effective for treating this disease.
Much analysis of statistical information regarding the proliferation of hypertension in the United States has been reported.
The relationship of stress to hypertension has a significant history.
There is strong evidence of early cardiac morphologic changes (greater left ventricular wall thickness and mass) and altered peripheral vascular capacity and responsivity to pressor stimuli among normotensive individuals with a positive family history.
In contrast, cardiac output, sodium consumption, intravascular volume, and cardiovascular responses to isometric exercise and standing do not differ in persons with and without a family history of hypertension.
By comparing normotensive individuals with and without a family history of hypertension, these investigations seek to identify potential pathophysiologic factors that predate the development of high blood pressure.
The research literatures summarized here represent four general areas: 1) cellular salt transport mechanisms, 2) dietary sodium, intravascular volume, and renal function, 3) cardiovascular morphology and physiology, and 4) cardiovascular reactivity.
