| Cardioglycosides | Class of drugs derived from the foxglove plant |
| Diastolic blood pressure | Measure of blood pressure when the heart is at rest |
| Digitalization | Method of dosage with cardioglycosides that rapidly produces effective drug levels |
| Ejection fraction | Percentage of blood ejected from the left ventricle with each heart beat |

| Ischemia | Deficient blood supply to an area of the body |
| Ishemic heart disease | Condition is which heart muscle is damaged because of an absence of blood supply |
| Metabolic syndrome | Risk factor of hypertension that promotes the development of atherosclerosis and cardiovascular disease |
| Natriuretic peptides | Hormones that play a role in cardiac homeostasis |
| Necrosis | Cell death that may be caused by lack of blood and oxygen |
