High pressure 117mmHg low pressure 50mmHg blood pressure is not normal, low pressure is too low, the pulse pressure difference is large, there may be coronary atherosclerosis, hyperthyroidism, aortic sclerosis, heart valve disease and other diseases. Normal blood pressure is low pressure between 60-79mmHg, high pressure between 90-119mmHg, pulse pressure difference in 30-40mmHg. Therefore, high pressure 117mmHg low pressure 50mmHg blood pressure is not normal, low pressure is too low, the pulse pressure difference reaches 67mmHg, belong to the pulse pressure difference is seriously elevated. Generally speaking, a large pulse pressure difference and low pressure may be a manifestation of coronary atherosclerosis, hyperthyroidism, aortic sclerosis, heart valve disease, etc.. If left untreated, it may cause serious problems such as myocardial infarction and heart failure. Therefore, those with high pressure of 117mmHg and low pressure of 50mmHg should consult a doctor in time for further examination to clarify the cause of the disease.
