A high pressure of 180 mmHg may be associated with a burst blood vessel, but it is a combination of the patient’s usual blood pressure. High pressure, or systolic pressure, refers to the pressure on the walls of blood vessels caused by the ventricles shooting blood into the aorta when the heart contracts. A threshold of 140 mmHg is used, and a diagnosis of hypertension is made above 140 mmHg. If there is an occasional systolic pressure of 180 mmHg, a bursting of the blood vessel does not necessarily occur, but a prolonged systolic pressure reaching 180 mmHg, a condition that is considered tertiary hypertension, is also the most serious one. Long-term occurrence of this condition may be complicated by cardiovascular and cerebrovascular diseases, such as coronary heart disease, acute myocardial infarction, cerebral atherosclerosis, cerebrovascular stenosis and other diseases, and even lead to cerebral hemorrhage. Therefore, when systolic blood pressure of 180 mmHg occurs, do not worry too much, go to the hospital as soon as possible and under the guidance of the doctor for the purpose of lowering blood pressure.
