The platelet pressure product 0.320% is higher than normal, generally the normal value of platelet pressure product for men is 0.108%-0.272%, and the normal value of platelet pressure product for women is 0.114%-0.282%, and the problem is closely related to the etiology that causes elevated platelet pressure product. The reason for the elevated platelet pressure product is various, such as primary thrombocytopenic purpura, megaloblastic anemia, splenectomy, etc. 1, primary thrombocytopenic purpura: primary thrombocytopenic purpura is an immune disease, characterized by the body in the blood circulation, the presence of platelet antibodies to platelets are too much destruction, thus causing the phenomenon of high platelet pressure product occurs. Patients will be at risk of internal bleeding, which is life-threatening and can manifest as bleeding gums and nasal bleeding, which is a bigger problem and requires timely hospitalization. 2. Megaloblastic anemia: an increase in the average platelet volume can also occur, resulting in a platelet backlog of 0.320%. This is when severe anemia can lead to myocardial ischemia in patients, manifestations of panic, chest tightness and chest pain, as well as symptoms of the digestive tract and reduced digestive and absorption functions. Compared to primary thrombocytopenic purpura the problem is relatively small, but also needs to be dealt with as soon as possible; 3. Splenectomy: splenectomy, causing an increase in platelet count, will lead to an increase in platelet pressure accumulation. At this time, platelet pressure buildup 0.320 is not a big problem, usually just pay attention to monitor blood routine, pay attention to drink more water, reduce the risk of thrombosis caused by platelet increase; 4, other: bone marrow proliferative tumor, can also trigger platelet count increase, resulting in platelet pressure buildup 0.320%, such as chronic granulocytic leukemia, true erythropoietic disease, primary thrombocytosis, etc.. This is when the patient will have a greater problem with the increased risk of thrombosis, cerebral thrombosis, pulmonary infarction, mesenteric thrombosis, etc., due to the marked increase in platelet count.
