Heterozygous Familial Hypercholesterolemia With APOE Haplotype: A Prospective Harbinger of a Catastrophic Cardiovascular Event.

We report a very young man with heterozygous familial hypercholesterolemia (FH) with APOE haplotype and a significant cardiac family history who underwent cardiac catheterization for intermittent episodes of exertional dyspnea and was noted to have a severe triple vessel coronary artery disease (CAD). He underwent coronary artery bypass graft (CABG) surgery which was uneventful. He was discharged on antiplatelet, beta blocker, nitrate, and statin. On routine health maintenance evaluation, he had no cardiac complaints and had been tolerating well his activities of daily living.
