Cardiomegaly is a medical term referring to an enlarged heart. It denotes an abnormal increase in heart size detectable via imaging or clinical examination and can be a sign of underlying cardiac disease or physiological adaptation. The term is used in professional medical contexts and may appear in patient discussions when describing diagnostic findings.
"The cardiomegaly detected on the chest X‑ray prompted further cardiology evaluation."
"An echocardiogram confirmed cardiomegaly with regional wall motion abnormalities."
"Long-standing hypertension can lead to cardiomegaly as the heart works harder to pump blood."
"In cases of cardiomegaly, management focuses on treating the underlying cause and monitoring cardiac function."
Cardiomegaly originates from the Latin root cardio-, meaning heart, and megal- meaning large or oversized, with the medical suffix -megaly denoting enlargement. The word combines cardio- (heart) + megaly (enlargement). The first component derives from Greek kardia “heart,” while megaly comes from Greek megalein “to enlarge.” In the history of medical terminology, -megaly appeared in the 17th–19th centuries to describe organ enlargements (e.g., acromegaly, splenomegaly). Cardiomegaly entered modern medical lexicon as imaging and autopsy techniques allowed precise assessment of heart size, particularly with chest radiographs and echocardiography. It is used in clinical notes to denote an abnormal size that may be accompanied by functional impairment or be a compensatory response to other conditions such as hypertension, valvular disease, or cardiomyopathy. The term communicates a diagnostic finding rather than a specific disease, guiding further evaluation and management. Etymologically, the components are standard across scientific language: cardio- (heart) from Greek kardia, -megaly from megalein (to enlarge) from Greek megas (great). The evolution reflects a shift from purely descriptive terms to precise radiological and echocardiographic criteria for heart size, with cardiomegaly now commonly assessed by cardiologists in conjunction with functional measures and clinical context.

Pronounce as kar-dee-oh-MEG-uh-lee with primary stress on the meg syllable. IPA: US ˌkɑrdiˌoʊˈmɛɡəli, UK ˌkɑːdɪəʊˈmɛɡəli, AU ˌkaɾdɪˈoːmɛɡəli. Break it into three parts: cardio- (heart) + -megaly (enlargement), with the second-to-last syllable bearing the main stress. Start with a clear ‘kar’ or ‘ka’ sound, then a gentle ‘dee,’ then emphasize ‘meg,’ followed by a quick ‘uh-lee.’ Audio cue: listen for the vowel quality in the middle and the final syllable’s light, unstressed ending.
Common errors include shifting stress to the final syllable and mispronouncing the 'meg' as ‘mega’ with a long ‘e.’ Another frequent mistake is combining it as ‘cardio-me glue’ or ‘cardio-may-gly,’ which distorts the -megaly ending. Correct by keeping three syllables, stressing meg- (the second-to-last strong syllable), and ending with a short, light -ly. Practice the middle ‘oh’ or ‘o’ sound and ensure the ‘g’ is soft, not a hard ‘g’ into a ‘ee’ sound.
In the US, you’ll hear /ˌkɑːrdioʊˈmɛɡəli/ with rhotic r and a tense second syllable. UK English tends toward /ˌkɑːdɪəʊˈmeɡəli/ with a schwa-influenced second syllable, and non-rhoticity may soften r sounds. Australian tends to /ˌkɑːdiəʊˈmeɡəli/ with clear vowel distinctions and a lightly rolled or tapped r depending on speaker. Across accents, the meg- syllable carries primary stress; vowel quality of the second vowel and the final -ly sound can shift subtly.
The difficulty comes from the long multisyllabic structure, the cluster of vowels in the cardio- and -megaly parts, and the mid-word stress. The sequence ‘di-o-meg’ requires a clean transition between /d/ + /i/ + /oʊ/ and /ˈmɛɡə/; many speakers insert extra vowels or place stress on the wrong syllable. Additionally, the ending -meg- a-ly yields a light, quick final syllable that’s easy to swallow unintentionally. Focus on syllable separation and stable vowel sounds.
Cardiomegaly is phonologically straightforward: all letters are pronounced, and the word has a clear three-syllable structure with primary stress on meg- (car-di-O-MEG-a-ly in rough US rhythm, but standard three-syllable rhythm places emphasis on the third segment meg-). There are no silent letters. The challenge is ensuring correct vowel qualities and not gliding the -ly into -lee too slowly. Emphasize the -meg- syllable while keeping the final -ly light and quick.
