Patients with hypertension can develop thrombosis, which usually has the following causes: 1. Blood vessel stenosis is the main factor in thrombosis, in addition to slowed blood flow or high blood viscosity, which can accelerate the formation of thrombosis. 2. In addition to blood damage to the endothelium of blood vessels, which can also lead to thrombosis. For patients with hypertension, it will lead to damage to the endothelium, promote the occurrence of atherosclerosis, and slow down the blood flow, so it will aggravate the formation of thrombosis, so hypertension is already an independent risk factor for thrombosis. For patients with hypertension, not only do they need long-term antihypertensive drugs to control blood pressure, but they also need to go to the hospital regularly to check whether they have hypertension combined with other risk factors such as hyperlipidemia, diabetes or atherosclerosis, and if they have these conditions, they are very likely to form thrombosis.
