1 Place your baby on his or her back to sleep, but don't worry if your little one picks another sleep position. If you have any questions about your baby's sleep position, talk to your doctor.  Make sure your crib meets current safety standards.
Definitions and Classification of Blood Pressure Levels. Essential, primary, or idiopathic hypertension is defined as high BP in which secondary causes such as renovascular disease, renal failure, pheochromocytoma, aldosteronism, or other causes of secondary hypertension or mendelian forms (monogenic) are not present. Essential hypertension accounts for 95% of all cases of hypertension.
Essential hypertension is a major risk factor for cardiovascular disease and is one of the main causes for congestive heart failure, stroke, and renal disease in Western societies. Despite intensive research in this field, the exact etiology of essential hypertension is still unknown.
