A blood pressure of 142 mmHg is classified as grade 1 hypertension. The normal range of blood pressure in normal adults is between 90-139 mmHg systolic and 60-89 mmHg diastolic, and if the blood pressure is ≥140/90 mmHg, it is considered hypertensive. Hypertension can be divided into 3 levels. For patients with grade 1 hypertension, if the patient has no target organ damage and no combined cardiovascular disease, they belong to the low-risk risk stratum and can undergo dietary and lifestyle interventions, with a low-salt, low-fat diet and weight control. If a patient has grade 2 hypertension, he or she should be treated with antihypertensive drugs and lifestyle interventions. Lifestyle interventions mainly involve changing poor diet and lifestyle habits, quitting smoking and alcohol, avoiding overexertion, and monitoring blood pressure to keep it within the normal range.
