Differential Diagnosis for Probable Cardiomegaly

Single Most Likely Diagnosis

  • Hypertension: This is often the most common cause of cardiomegaly due to the increased workload on the heart, leading to ventricular hypertrophy and eventual enlargement.

Other Likely Diagnoses

  • Heart Failure: Both systolic and diastolic heart failure can lead to cardiomegaly due to the heart's inability to efficiently pump blood, resulting in enlargement.
  • Coronary Artery Disease: Myocardial infarctions can lead to areas of dead tissue, causing the heart to work harder and potentially enlarge.
  • Valvular Heart Disease: Conditions such as mitral regurgitation or aortic stenosis can increase the workload on the heart, leading to hypertrophy and dilation.

Do Not Miss Diagnoses

  • Cardiac Amyloidosis: A condition where abnormal proteins deposit in the heart, leading to restrictive cardiomyopathy and potential for sudden death if not diagnosed.
  • Hypertrophic Cardiomyopathy: A genetic condition that can lead to sudden cardiac death, especially in young athletes, due to abnormal thickening of the heart muscle.
  • Pericardial Effusion: Accumulation of fluid in the pericardial space can compress the heart, leading to cardiac tamponade, a life-threatening condition.

Rare Diagnoses

  • Fabry Disease: A genetic disorder leading to the accumulation of a particular type of fat in the body's cells, affecting many parts of the body including the heart.
  • Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC): A rare heart condition where the muscle in the right ventricle is replaced by fat and scar tissue, potentially leading to life-threatening arrhythmias.
  • Left Ventricular Non-compaction: A rare cardiomyopathy characterized by a spongy appearance of the left ventricle, which can lead to heart failure and arrhythmias.
