High blood pressure causes many diseases.

Hypertension can cause diseases such as retinopathy, heart failure, cerebral infarction, etc. The specific analysis is as follows:

1. Retinopathy

Hypertension can cause high blood vessel tension in the eyes of patients, leading to spasm and gradual hardening of retinal arterioles, resulting in retinal lesions, blurred vision, retinal hemorrhage and other symptoms.

2. Heart failure

If patients are in a state of hypertension for a long time, it will lead to atherosclerosis changes, increase the resistance of blood vessels, lead to increased burden on the heart, lead to ventricular hypertrophy, ventricular shape and size changes, resulting in heart failure.

3. Cerebral infarction

Long-term hypertension can lead to rupture of the intima of arterial vessels, leading to a large number of platelet coagulation in the repair process, forming thrombosis, leading to arterial occlusion, brain tissue ischemia and hypoxia necrosis, resulting in cerebral infarction.
