A blood pressure of 142 mmHg systolic is an abnormal blood pressure, and according to the level of hypertension belongs to grade 1 hypertension, also called mild hypertension. Patients with a systolic blood pressure of 142 mmHg can first undergo active therapeutic lifestyle management, such as increasing exercise, keeping weight in the normal range, quitting smoking, limiting alcohol, and eating a low-salt, low-fat diet, etc. If the blood pressure can be restored to normal, there is no need to take blood pressure-lowering drugs for the time being. If, after active lifestyle modification, blood pressure is still elevated or the patient’s risk stratification for hypertension is high risk or very high risk, antihypertensive drugs should be given for long-term antihypertensive treatment, and clinical first-line antihypertensive drugs should be selected to achieve individualized antihypertensive treatment to achieve long-term blood pressure control.
