Get an Original Essay High blood pressure is known as the “silent killer.” It is expected that by 2025, the number of patients diagnosed with hypertension will be 1.56 billion.(3)Hypertension is responsible for over 7 million deaths per year(4)among the main risk factors for mortality for cardiovascular disease.(5)Disease is defined as systolic blood pressure (SBP) of 140 mmHg or diastolic blood pressure (DBP) = 90 mmHg, or any person currently prescribed antihypertensive medications for the purpose of managing hypertension. (1,2,6) Furthermore, hypertension is defined as elevated blood pressure values ​​on at least two occasions with or without provocation. (1) Hypertension is divided into two main categories: essential/primary hypertension and secondary hypertension. (7,8) The lack of identifiable causal factors for elevated blood pressure is known as essential or primary hypertension, which accounts for approximately 90%–95% of all hypertension cases. Secondary hypertension, for which there is an identifiable cause, affects 5% to 10% of US adults diagnosed with hypertension. Blood pressure is normally distributed in the population and there is no natural cut-off point above which "hypertension" definitively exists and below which it exists which is not true. Epidemiological studies demonstrate that the aforementioned disease risk associated with blood pressure is a continuous relationship and above blood pressures of 115/70 mmHg, the risk of cardiovascular events doubles for every 20/10 mmHg increase in blood pressure. The blood pressure threshold for hypertension is defined as the blood pressure level above which treatment has been shown to reduce the development or progression of the disease. Primary hypertension was previously called “essential hypertension” because of the long-held view that high blood pressure was sometimes “essential” to perfuse diseased, sclerotic arteries. It is now recognized that diseased and sclerotic arteries were very often the consequence of hypertension and therefore the term "essential hypertension" is redundant and "primary hypertension" is preferred.

Get a Custom Essay Primary hypertension refers to the majority of people with prolonged high blood pressure (about 90%) encountered in clinical practice, for which there is no obvious, identifiable cause. The remaining 10% is defined as “secondary hypertension” for which the specific causes of the increase in blood pressure can be determined.
