Long-term iron deficiency anemia can impair cardiac function. Anemia tends to cause increased heart rate in patients, and sometimes leads to accelerated constriction of the heart's blood vessels, triggering symptoms such as palpitations. Anemia easily induces myocardial hypoxia; chronic anemia may result in insufficient blood supply to the heart or lead to anemic heart disease. In anemic patients, reduced red blood cell count and decreased hemoglobin levels cause ischemia and hypoxia in tissues and organs. To maintain adequate blood supply to various organs, the heart compensates by increasing heart rate and cardiac output. This overloads organs, leading to myocardial hypertrophy, cardiac enlargement, reduced contractility, and in severe cases, heart failure.
