There are many factors that can cause calcification of the pulmonary arteries, and common high-risk factors such as pulmonary atherosclerosis, hypertension, and diabetes mellitus. Commonly used drugs include lipid-lowering drugs such as resuvastatin, antiplatelet drugs such as aspirin, antihypertensive drugs such as amlodipine, and hypoglycemic drugs such as metformin. Combined with the characteristics of their own conditions, under the guidance of the doctor to use the appropriate medication program. 1. Atherosclerosis: lipid-lowering drugs such as Rosuvastatin, which can inhibit HMG-CoA reductase and reduce cholesterol synthesis. Antiplatelet drugs such as aspirin, which can inhibit cyclooxygenase, reduce the generation of thromboxane A2 in platelets, inhibit platelet aggregation and prevent thrombosis. 2. Hypertension: antihypertensive drugs such as amlodipine, which can block calcium channels, so that intracellular calcium ions fall and relax vascular smooth muscle, thereby reducing blood pressure. 3. Diabetes: hypoglycemic drugs such as metformin, which can inhibit glucose absorption in the intestine and glycogen isomerization, inhibit the release of glucagon. With age, the blood vessels of the elderly undergo sclerosis, the elasticity is weakened, and calcium in the blood is easily deposited on the walls of the tubes to form arterial calcification. This condition can be treated without medication, but usually attention should be paid to a low-salt and low-fat diet, less smoking, less alcohol, and appropriate exercise. If pulmonary artery calcification occurs, you should go to the hospital in time, do not self-medication, so as not to delay the condition or adverse reactions, follow the doctor’s instructions for treatment.
