In November of the previous year, Mr. Gao’s blood pressure was found to be as high as 160/100 mmHg during a physical examination, and monitored for seven consecutive days, his blood pressure was higher than normal, and the cardiologist gave him a diagnosis of hypertension. However, for nearly half a year, while taking medication as prescribed by the doctor, Mr. Gao’s blood pressure was not stable and fluctuated widely, and he changed several treatment plans without any significant effect. Mr. Gao has suffered from cervical spondylosis for many years, and his symptoms worsened after the Spring Festival this year. In mid-February, Mr. Gao went to the hospital for treatment of his cervical spine. When Mr. Gao’s years of cervical spondylosis discomfort disappeared, he unexpectedly found that his blood pressure had also returned to normal. While Mr. Gao was pleased, he also wondered if his high blood pressure in the past was related to cervical spondylosis. Is it possible that cervical spondylosis can cause high blood pressure? The answer to this question is yes. It is related to the malfunction of the blood supply to the vertebrobasilar artery caused by cervical spondylosis and the dysfunction caused by the stimulation of the sympathetic nerves in the neck. The cervical sympathetic ganglion is attached to the transverse process of the cervical spine, and cervical misalignment that displaces the transverse process, or sterile inflammation caused by cervical misalignment injury, can lead to sympathetic excitation, and cerebral vasospasm and increased blood pressure can occur. If such stimulation persists, it will secondary affect the function of cerebrovascular diastolic center, and develop into systemic small artery spasm, which makes blood pressure continuously increase. There are many causes of hypertension, and although the proportion of hypertension caused by cervical spondylosis is small, it is easy to delay the condition due to misdiagnosis. So what are the characteristics of hypertension caused by cervical spondylosis? In addition to high blood pressure, there are also symptoms of cervical spondylosis, such as headache, dizziness, stiffness and pain in the back of the neck and shoulders, weakness in the upper limbs, and numbness in the fingers. When the symptoms of cervical spondylosis are aggravated, the blood pressure rises even more; when the symptoms of cervical spondylosis are relieved, the blood pressure may then decrease. X-ray examination can reveal the manifestation of degenerative changes in the cervical spine. The effect of using antihypertensive drugs is not obvious, or the blood pressure is unstable, but when cervical spondylosis is effectively treated, the blood pressure also drops to normal or close to normal. Therefore, for patients with unsatisfactory blood pressure control with medication and no family history of hypertension, those with symptom onset similar to the characteristics of cervical spondylosis may wish to take cervical spine X-ray or cervical spine CT film first to exclude cervical spondylotic hypertension. However, cervical spondylosis does not always have hypertension, and hypertension is not always due to cervical spondylosis. Therefore, do not neglect the treatment of primary hypertension; after all, hypertension due to cervical spondylosis is relatively rare, and most of it is still primary hypertension. Especially in middle-aged and elderly people, two diseases exist at the same time, whether they suffer from cervical spondylosis or hypertension first, which is sometimes difficult to distinguish clinically; and some patients have both diseases together, so we should consider both diseases at the same time when treating them, so as not to lose sight of the other.
