高血压(htn) orhigh blood pressure, sometimes动脉高血压, is a chronic medical condition in which the blood pressure in the arteries is elevated. This requires the heart to work harder than normal to circulate blood through the blood vessels. Blood pressure involves two measurements, systolic and diastolic, which depend on whether the heart muscle is contracting (systole) or relaxed (diastole) between beats. Normal blood pressure is at or below 120/80 mmHg. High blood pressure is said to be present if it is persistently at or above 140/90 mmHg.

高血压被归类为主要(必需)高血压或继发性高血压;大约90%至95%的病例被归类为“原发性高血压”,这意味着没有明显潜在医疗原因的高血压。其余5-10%的病例(次要高血压)是由影响肾脏,动脉,心脏或内分泌系统的其他疾病引起的。

高血压is a major risk factor for stroke, myocardial infarction (heart attacks), heart failure, aneurysms of the arteries (e.g. aortic aneurysm), peripheral arterial disease and is a cause of chronic kidney disease. Even moderate elevation of arterial blood pressure is associated with a shortened life expectancy. Dietary and lifestyle changes can improve blood pressure control and decrease the risk of associated health complications, although drug treatment is often necessary in patients for whom lifestyle changes prove ineffective or insufficient.
