Symptoms depend on the type of heart disease. The term “heart disease” is often used interchangeably with the term “cardiovascular disease,” which refers to conditions that can narrow or block the blood vessels and may lead to myocardial infarction, chest pain, angina, or stroke. heart infections such as pericarditis (categories 420 and 423), myocarditis (category 422 or 429.0), and endocarditis (categories 421 and 424) and.congenital heart defects (categories 745 to 746).coronary artery disease (CAD) (ICD-9-CM category 414).Heart disease is a general term that involves a wide range of diseases affecting the heart and blood vessels, including the following:
