Hypoalphalipoproteinemia (HA) is associated with an increased risk of recurrent coronary episodes and mortality caused by coronary heart disease (CHD), and it constitutes a significant risk factor for the development of premature (accelerated) atherosclerosis.

  • In general, approximately 14 million people in the United States have CHD, many of whom exhibit associated HA. CHD remains the most common cause of death in the industrialized world. Approximately 1.5 million acute myocardial infarctions (MIs) occur each year in the United States; of patients experiencing acute MI, 500,000 die (almost 33%). Survivors experience an ever-increasing incidence of congestive heart failure, arrhythmias, and other forms of morbidity.

  • The incidence of stroke is also quite high. An estimated 600,000 new and recurrent cases of stroke occur each year, with 160,000 deaths per year. Stroke has become a leading cause of serious, long-term disability. Approximately 4.4 million stroke survivors live in the United States today; stroke not only exacts a huge cost in human suffering, it takes a financial toll as well, with the care of patients who have suffered a stroke reaching approximately $45.3 billion.

  • Peripheral vascular disease also affects many individuals. Approximately 50% of patients who report claudication have peripheral vascular disease.
