Problem: A 37-year-old male attends an appointment with his primary care provider. The patient has a history of early-onset atherosclerotic cardiovascular disease (ASCVD), having recently experienced a myocardial infarction (MI). He has no history of hypertension, diabetes, or renal disease. His family history is unremarkable. At the time of his MI, the patient underwent an extensive evaluation of his ASCVD risk factors, including a cholesterol panel. He was found to have a modestly elevated level of low-density lipoprotein cholesterol (LDL-C) at 128 mg/dL (SI units: 3.3 mmol/L) elevated non-high-density lipoprotein cholesterol (non-HDL-C) level of 162 mg/dL (SI units: 4.2 mmol/L). Due to the patient's lack of traditional risk factors for early ASCVD (other than his mildly elevated LDL-C),a lipoprotein(a) (Lp(a)) level was requested. This result is now available and shows an elevated Lp(a) of 50 mg/dL (SI units: 125 nmol/L). What is the diagnosis? What if any additional diagnostics are required? What is your plan of care?
