These young MI patients have high mortality rates, and many of them are not able to reach the hospital. The pathophysiology of AMI is very well understood. AMI is a multifactorial disease and has several risk factors, like dyslipidemia, diabetes, hypertension, smoking, diet, etc. However, low-density lipoprotein cholesterol (LDL-C) has a very strong causal relationship with atherosclerosis. Reducing LDL-C to <70 results in the arrest of the progression of atherosclerosis, and slashing its level to below 50 produces the regression of atherosclerosis. The cumulative exposure of LDL-C to the arterial wall is a very strong determinant of atherosclerosis and the development of AMI. The coronary heart disease (CHD) threshold target of LDL-C for the development of AMI is roughly 7000 mg/year. If LDL-C is 100 mg/dL from an early age, the CHD threshold target for the development of AMI will reach 70 years of age. However, if LDL-C target is <70 mg/dL from an early age, the patients will reach the CHD threshold of LDL-C at the age of 100 years. Based on the current science, this is an emerging concept to postpone AMI by several years, even up to 100 years. The goal of LDL-C <70 mg/dL can be achieved by available oral or injectable drugs. Gene editing with CRISPR technology is emerging as a very exciting modality for lowering LDL-C to a very low level for the rest of life.展开更多
