Hypertension and coagulation generally do not have a particular impact on the role of the two exist in different systems, hypertension is a cardiovascular system disease, while coagulation is a hematologic disease. People with high blood pressure may need to apply antiplatelet drugs, such as aspirin, if they have a combination of long-term diabetes, obesity, and increased blood lipids or atherosclerotic diseases such as coronary heart disease or stroke, which have a certain increase in the risk of bleeding, and people with high blood pressure who have a combination of long-term coagulation abnormalities, the application of antiplatelet drugs may exacerbate the risk of bleeding. Long-term hypertension may also lead to atrial fibrillation and other cardiac arrhythmias, in which case anticoagulant drugs are needed to prevent thrombosis, and people with abnormal coagulation function may aggravate the risk of bleeding. For people with usual high blood pressure who have a combination of coagulation abnormalities, it is important to look for the cause of the condition first, and to treat any complications that exist according to the situation.
