1.Whether it is positively correlated with cervical spine symptoms: The rise and fall of blood pressure in cervicogenic hypertension is synchronized with the onset of cervical spine disease and is inseparable. When a patient has an attack of cervical spondylosis there is often cervical pain, stiffness, headache, dizziness and other symptoms of cervical spondylosis, when the blood pressure rises; after the head and neck symptoms are relieved, the blood pressure also falls. This is an important feature of cervical spondylosis hypertension, which is especially obvious in the early stage of the disease, and gradually decreases with the prolongation of the disease. This is because hypertension is related to the degree of vertebral instability or subluxation, and to a certain extent, osteophytes or ossification of the anterior longitudinal ligament enhance the stability of the spine. The effect of abnormal organism proliferation on local neurovascularity is mitigated. And the symptoms of primary hypertension are not related to the symptoms of cervical spondylosis. 2, intervention on antihypertensive drugs: both are effective on blood-activating drugs and vasodilators. Primary is good for antihypertensive drug treatment, while secondary cervical spondylosis hypertension is mostly insensitive to antihypertensive drugs. The treatment of cervical spondylosis is effective, especially cervical traction and manipulation. With the improvement of the cervical spondylosis, the blood pressure basically stabilized. In the 24-hour ambulatory blood pressure observation conducted, after traction and manipulation for cervical spondylosis, the patient’s blood pressure could drop by 20-30 mmHg, and the blood pressure would rise again in the interval between treatments. 3, symptom characteristics and active exclusion: various forms of hypertension and cervical spondylosis in the development of the disease process, may appear blood pressure fluctuations, dizziness, dizziness, memory loss, general weakness and other symptoms. Therefore, for patients with unsatisfactory blood pressure control with hypertension medication, especially those with no family history of hypertension and symptom onset with similar characteristics of cervical spondylosis, consider taking cervical spine X-ray or cervical spine CT scan or magnetic resonance MRI first to exclude cervical spondylotic hypertension secondary to cervical spondylosis. 4, blood pressure characteristics: patients with cervicogenic hypertension mostly present with large fluctuations in blood pressure, small pulse pressure difference, lower blood pressure after drug control, significantly higher blood pressure after stopping drugs, or a period of hypotension, a period of hypertension, or a period of unstable blood pressure fluctuations. Therefore, if a patient with cervical spondylosis has hypotension or unstable blood pressure, the possibility of becoming hypertensive should be thought of.
