Diagnosis and differential diagnosis of hypertension

The World Health Organization recommends the use of the diagnostic criteria for hypertension is: Normal adult blood pressure: systolic 18.66 kpa or less, diastolic blood pressure (whichever is the voice disappeared) 11.99 kpa or below. Hypertension (adult): SBP 21.33 kpa or above, and (or) DBP 12.66 kpa or more. Borderline hypertension: blood pressure in the above-mentioned values between normal and high blood pressure. Where blood pressure continued to achieve higher standards of hypertension, and may be excluded from secondary hypertension, can be diagnosed with hypertension. Found that the initial high blood pressure patients, many times to review the same day blood pressure, especially non-blood pressure, fear of mental stress, emotional or physical activity caused by the temporary blood pressure, early misdiagnosed as hypertension. On the question of patients, to the period of observation to the conclusion for properly.
Clinical generally be measured is divided into three types of hypertension, contribute to the development of disease control and the development of rational control measures. ① first phase: blood pressure level reached diagnosed hypertension, clinical unmotivated, brain and kidney complications. ② Phase II: Blood pressure level reached diagnosed hypertension, and one of the following: physical examination, x line, ECG or ultrasound have left ventricular hypertrophy; retinal artery generally small or local variable; proteinuria and serum creatinine concentration mild increased. ③ Phase III: Blood pressure level reached diagnosed hypertension, and one of the following: cerebral hemorrhage or hypertensive encephalopathy; left heart failure, renal failure; or exudative retinal hemorrhage, papilledema dispensable. Differential diagnosis to consider: An acute and chronic nephritis; 2 chronic pyelonephritis; 3 pheochromocytoma; 4 primary aldosteronism; 5 renovascular hypertension.
