Blood pressure is high when high pressure is high and low when low pressure is low, meaning that the patient currently has a high systolic blood pressure and a diastolic blood pressure that may be normal or below normal. The cause of this condition is most often seen in elderly patients, who often have atherosclerosis, and in severe cases of atherosclerosis, an increase in the difference in pulse pressure can occur. For such patients, the first step is to improve the atherosclerosis and improve the insufficient blood supply to the myocardium, which will help to further reduce the increased pulse pressure difference. At the same time, it is important to closely monitor blood pressure, do not lower the diastolic blood pressure too low, it is best to maintain the diastolic blood pressure between 65-80 mmHg, which is relatively the most ideal diastolic blood pressure. If you are currently taking antihypertensive drugs, you can properly adjust the use of antihypertensive drugs program, for this case, more suitable for oral calcium channel blockers, representative drugs have amlodipine, felodipine and so on.
