Statins are mainly used in the treatment of hypercholesterolemia and ischemic cardiovascular diseases. 1. Patients with hypercholesterolemia need to take oral statins for treatment. Patients without any risk factors can survive for a long time without any relationship with oral statins. 2. Severe ischemic cardiovascular and cerebrovascular disease, also need oral statin treatment, prone to acute complications, survival time may be shortened, different patients survival time is obviously different. 3.
