Hypertension is a chronic disease in which blood pressure is continuously elevated, usually referring to abnormally elevated arterial blood pressure. According to the World Health Organization, normal blood pressure for adults should be systolic pressure (high pressure) less than 140 mmHg and diastolic pressure (low pressure) less than 90 mmHg. Exceeding this standard is considered hypertension. Hypertension is often called the "silent killer". Most patients can develop the disease without any symptoms, and long-term higher-than-normal pressure on the blood vessel walls can lead to serious diseases such as coronary heart disease and stroke.
