Coronary artery calcification in 70-year-old patients should not matter depends on whether the coronary artery stenosis. Coronary artery calcification suggests that coronary artery atherosclerosis, and in the atherosclerosis of the local phenomenon of calcification; coronary artery calcification can only suggest that the blood vessels appear aging, coronary artery stenosis or not, but also to carry out coronary artery CTA or coronary arteriography of the examination, to make clear whether there is the coronary artery of the serious phenomenon. Calcification on the outside of the coronary arteries does not lead to significant stenosis within the coronary arteries, and the condition is not serious enough to control lipid levels; calcification of the inner lining of the coronary arteries can lead to stenosis of the coronary arteries, and for patients with severe stenosis, the severity of the condition will increase significantly, and medications such as aspirin and atorvastatin will need to be given to control the progression of the condition, and stents will need to be implanted in patients with severe stenosis. Patients with coronary calcification should be evaluated for the degree of coronary artery stenosis to determine the next course of treatment and be treated under the supervision of a cardiologist.
