高血压治疗中是否存在J形曲线在医学界已经争论了20多年,J点血压是否可以使高血压患者获益最大仍然没有明确。本文对近年来关于J形曲线正反两方面的研究作一综述,认为在强化降压治疗的同时,应根据不同的高血压人群选择不同的降压目标,对伴有左心室肥厚和缺血性心脏病的患者,应警惕舒张压过低的不良影响。 Whether there is a J-shaped curve in the treatment of hypertension has been debated in the medical profession for more than 20 years. Whether J-point blood pressure can benefit the hypertensive patients is still unclear. In this paper, the positive and negative aspects of the J-shaped curve in recent years to make a review of research, that in the treatment of intensive antihypertensive treatment, should be based on different hypertensive population to choose a different antihypertensive target, accompanied by left ventricular hypertrophy and ischemia Patients with heart disease, should be wary of the adverse effects of diastolic blood pressure is too low.
