A blood pressure of 150/90 is considered high-risk hypertension if it is associated with more risk factors, target organ damage, or comorbidities, which are more dangerous. Patients with grade 2 hypertension with clinical comorbidities or diabetes mellitus are very high-risk hypertensive patients; grade 2 hypertension with ≥3 other cardiovascular risk factors or target organ damage are high-risk hypertensive patients. Patients with grade 2 hypertension with 1-2 cardiovascular risk factors were classified as intermediate-risk hypertensive patients; patients with grade 2 hypertension without other cardiovascular risk factors, target organ damage or clinical comorbidities were classified as intermediate-risk hypertensive patients. Cardiovascular risk factors included: hypertension grade 1-3; age; smoking; abnormal blood glucose; abnormal blood lipids; family history of early onset cardiovascular disease; obesity; and elevated homocysteine. Target organ damage included: left ventricular hypertrophy, atherosclerotic plaque, renal function abnormalities, and urinary microalbumin. Clinical comorbidities: cerebral hemorrhage, cerebral infarction, myocardial infarction, angina pectoris, heart failure, diabetes mellitus, renal insufficiency, etc. Patients with hypertension, regardless of their risk stratification, should consult a doctor in the hospital and follow the doctor’s recommendations for antihypertensive treatment.
