Hypertension with dizziness and vomiting is often indicative of complications of hypertension. Hypertension usually causes complications in target organs, including cardiac complications, such as angina pectoris, myocardial infarction, and heart failure. In patients with myocardial infarction, elevated blood pressure followed by persistent chest pain with nausea, vomiting, and cold sweats requires electrocardiography, cardiac enzymes, and coronary imaging to clarify the diagnosis. For hypertension combined with target organ lesions of cerebrovascular, such as hemorrhagic stroke and ischemic stroke, patients may have symptoms such as dizziness, headache, hemiparesis, aphasia, nausea and vomiting, and it is recommended to give cranial CT, head and neck CTA examination to further clarify the condition. In addition, patients with hypertensive encephalopathy may also present with dizziness and vomiting.
