A blood pressure level of 150mmHg systolic and 100mmHg diastolic is the level of grade 2 hypertension and needs to be controlled with antihypertensive medication. Generally, the blood pressure needs to be controlled below 140/90mmHg, and preferably below 130/80mmHg when the patient can tolerate it. However, when hypertensive patients are combined with other risk factors, such as diabetes mellitus, coronary artery disease, heart failure, renal failure, stroke, etc., it is required to control the blood pressure below 130/80mmHg in order to minimize the continual damage to target organs caused by the excessively high blood pressure. However, for the elderly hypertensive patients, because of the long time suffering from hypertension, the body has adapted to the higher blood pressure, and the elasticity of the large blood vessels decline, suddenly reduce the blood pressure may cause the body can not adapt to the lower blood pressure resulting in insufficient blood supply to the tissues and organs, therefore, the elderly lowering of blood pressure is generally used to lower blood pressure in stages. First control at about 150/90mmHg, maintain for a period of time, and then further control at below 140/90mmHg after adaptation. In case of elevated blood pressure, one should consult a doctor in time, follow the doctor’s instructions for treatment, and have regular checkups.
