Description

technical field

[0001] The invention relates to the technical field of current detection, in particular to a current peak detection device, a high-voltage generator and vascular calcification treatment equipment. Background technique

[0002] Vascular calcification refers to the pathological process in which hydroxyapatite minerals are deposited in the vascular system. It is more common in atherosclerotic plaques, diabetes, aging and chronic renal failure, blood vessels and heart valves in uremia. Clinical and epidemiological data show that vascular calcification is a common clinicopathological manifestation in patients suffering from atherosclerosis, hypertension, diabetic vascular disease, vascular injury and chronic kidney disease, and is an important risk factor for cardiovascular events , present in 80% of vascular injuries and 90% of coronary artery disease. Vascular calcification in infancy, uremic arteriolar calcification, and calcified valvular disease can be life-...
