Blood pressure of 150/90 mmHg after cardiac stenting is not normal. Blood pressure after cardiac stenting should be controlled below 130/80 mmHg, and diastolic blood pressure of 70 to 80 mmHg is appropriate. Blood pressure of 150/90mmHg after cardiac stenting is high. Elevated blood pressure after cardiac stenting may be caused by the patient’s own hypertension or by the improved blood supply to the heart after the operation. High blood pressure will accelerate the progression of atherosclerosis and cause the patient to gradually develop heart failure, so the blood pressure should be controlled within the target blood pressure. In addition to controlling blood pressure, lipids and blood sugar should also be controlled to prevent recurrence of myocardial infarction. Patients with high blood pressure after cardiac stenting should take antihypertensive drugs, such as nifedipine and metoprolol, under the guidance of doctors. At the same time, in order to avoid blood vessel infarction, should also take antiplatelet drugs, such as aspirin, clopidogrel and so on. Abnormal blood pressure after cardiac stent, timely medical treatment to avoid the development of the disease.
