Cardiovascular disease (CVD) is a common illness, afflicting one in every three individuals in the United States. The effects of CVD can vary from simple high-blood pressure to a fatal stroke. Interventional cardiology is primarily applied to the treatment of coronary heart disease (CHD), which is a specific cardiovascular illness. CHD encompasses myocardial infarction (MI) and angina pectoris, diseases that account for over half of all CVD cases.
The potential patient population for interventional cardiology devices is typically defined as those who are at risk of developing angina or suffering from myocardial infarction. In the U.S., men over 45 years of age and women over 55 years of age are considered at high risk for these conditions. In 2017, the population of the U.S. was estimated to be almost 325 million, with 138 million people in the high risk category.
According to the American Heart Association, over 13 million people suffer from CHD, with six million suffering from angina and seven million suffering from myocardial infarction. Men are more likely to have myocardial infarctions, whereas women are more prone to developing angina. CHD is responsible for one in every five deaths, and there are over one million coronary attacks per year in the United States. The probability of developing a CHD after the age of 40 is approximately 30% for women and nearly 50% for men. In most cases, myocardial infarctions occur in individuals who have had no prior symptoms of the disease, making preventative treatment difficult. Patients in the 60 to 69 age group are more likely to undergo an interventional procedure to treat CHD than any other age group.
