All About Hypertension
What is Hypertension? Hypertension is a disease of diverse causes. Which consists manifiestaa and the sustained increase in blood pressure in systole and diastole in or both. The increase in blood pressure (hypertension) is a major cause, but most likely treatment of disease and was divided into primary and secondary. In the general population, blood pressure is a continuous variable and its increase is associated with an increased risk of disease. Hypertension can be defined arbitrarily as a sustained diastolic pressure above 90 mmHg.
However, there is no risk of developing diseases in which blood pressure is a pathogenic factor. Primary hypertension (essential) is the elevation of blood pressure with age, but without apparent cause. It represents over 90% of cases and usually occurs after 40 years The phenotype of high blood pressure in hypertension is due to interaction between predisposition genetics, obesity, alcohol consumption, physical activity and other factors not yet identified. Secondary hypertension, which represents about 10% of cases, is due to an identifiable cause, the most common renovascular disease, which raises blood pressure by activating the renin-angiotensin-aldosterone system. Depending on their clinical evolution, both the primary and secondary hypertension can be classified into two types. In benign hypertension there is a steady rise in blood pressure for many years, while in hypertension accelerated the elevation of blood pressure is intense and worsens in a short period of time. Factors that regulate blood pressure may be elevated blood pressure by increasing cardiac output or peripheral vascular resistance.
