High hypotension refers to high diastolic blood pressure. Long-term elevated diastolic blood pressure may cause damage to the heart, blood vessels, kidneys and other target organs. 1. Cardiac damage: long-term elevated diastolic blood pressure may cause hypercardia, which is manifested by ventricular remodeling such as hypertrophy of ventricular muscle and enlargement of cardiac chambers, which leads to a decline in cardiac function and then develops into heart failure. 2. Vascular damage: long-term high diastolic blood pressure may have a reduced pulse pressure difference, such people’s blood vessel wall is relatively weak, and long-term elevated diastolic blood pressure may cause aneurysms and other vascular damage. 3. Kidney damage: long-term elevated diastolic blood pressure can lead to renal arteriosclerosis, which can cause renal insufficiency, and in severe cases, renal failure may occur. Long-term elevated diastolic blood pressure may cause certain damage to target organs such as zinc, brain, kidney, blood vessels, fundus, etc. It is necessary to actively treat under the guidance of a doctor and regularly take antihypertensive drugs in order to delay or prevent target organ damage.
