Unstable Angina is a clinical condition where chest discomfort from myocardial ischemia is new, worsening, or occurs at rest. It is a diagnosis within the acute coronary syndrome (ACS) spectrum, typically grouped with non–ST-elevation ACS. It is commonly encountered in emergency and inpatient cardiology when evaluating possible heart-related chest pain. It is defined by ischemic symptoms without evidence of myocardial infarction (heart muscle necrosis) on cardiac biomarkers.

Stable Angina is chest discomfort caused by predictable, temporary reductions in blood flow to the heart muscle. It is a clinical syndrome (a symptom pattern) most often related to coronary artery disease (CAD). It is commonly encountered in outpatient cardiology clinics and emergency triage when evaluating chest pain. It helps clinicians frame risk, select testing, and plan long-term cardiovascular prevention.

Coronary Embolism is a condition in which material traveling in the bloodstream suddenly blocks a coronary artery. It is a cause of acute myocardial ischemia and myocardial infarction (heart muscle injury) that is not primarily due to plaque rupture. It belongs to the category of cardiovascular conditions and acute coronary syndromes (ACS). It is commonly encountered when evaluating chest pain, ST-elevation myocardial infarction (STEMI), or myocardial infarction with “non-obstructive” coronary arteries.

Coronary Thrombosis is the formation of a blood clot (thrombus) inside a coronary artery. It is a cardiovascular condition that can reduce or stop blood flow to heart muscle. It is commonly encountered in cardiology in the setting of acute coronary syndrome (ACS) and myocardial infarction (heart attack). It is closely tied to atherosclerosis (plaque disease) and to clotting biology (platelets and coagulation).

Atherosclerosis is a chronic condition where plaque builds up in the walls of arteries. It is a vascular disease process (a condition), not a single symptom or test result. It is commonly encountered in cardiology when evaluating chest pain, heart attacks, and stroke risk. It also underlies many decisions about prevention, imaging, and revascularization planning.

Coronary Artery Disease is a condition in which the heart’s own blood supply becomes limited, most often due to atherosclerosis. It is a cardiovascular disease (a chronic condition) involving the coronary arteries. It is commonly encountered when evaluating chest pain, shortness of breath, or abnormal cardiac testing. It is a core topic in cardiology because it underlies many cases of myocardial ischemia and myocardial infarction.

Ischemic Heart Disease is a condition where the heart muscle does not receive enough oxygen-rich blood. It is most often caused by problems in the coronary arteries that supply the myocardium (heart muscle). It is a major diagnosis category in cardiology that includes stable angina and acute coronary syndromes. It is commonly encountered in chest pain evaluation, myocardial infarction workups, and long-term cardiovascular risk management.

Acquired Heart Disease is a broad clinical category that refers to heart and vascular conditions that develop after birth. It includes disorders of the coronary arteries, heart muscle, valves, pericardium, and cardiac conduction system. It is commonly encountered across outpatient cardiology, emergency care, inpatient medicine, and cardiac imaging. It is often discussed in contrast to congenital heart disease, which is present at birth.

Congenital Heart Disease is a group of structural problems in the heart or great vessels that are present at birth. It is a medical condition (a category of cardiovascular disorders), not a single diagnosis. It is commonly encountered in pediatrics, fetal cardiology, and adult congenital cardiology clinics. It is also a frequent reason for cardiac imaging, murmurs on exam, cyanosis evaluation, and long-term cardiology follow-up.

Structural Heart Disease is an umbrella term for abnormalities in the heart’s physical structures. It is a category of cardiovascular conditions, not a single diagnosis. It commonly involves the valves, chambers, septa, or great vessels. It is frequently encountered in general cardiology, echocardiography, heart failure care, and “structural heart” procedural programs.
