What term is used for unexpected death that occurs shortly after the onset of symptoms, often linked to cardiovascular disease?

The term "sudden death" specifically refers to an unexpected death that occurs rapidly, often in individuals who may have had underlying health issues, such as cardiovascular disease. This phrase captures the essence of a fatal outcome that happens quickly after a significant health change, typically without prior warning. This type of scenario is frequently observed in conditions related to heart health, where symptoms may present suddenly, leading to a swift decline and eventual death.

Other terms might describe certain events associated with cardiovascular issues, but they have more specific implications. Cardiac arrest refers to the cessation of heart function, which can lead to sudden death, but it doesn't encompass the broader context of unexpected death immediately following symptom onset. Serious arrhythmia denotes irregular heartbeats that may be dangerous but don't inherently imply a sudden death context. Acute myocardial infarction, commonly known as a heart attack, describes a specific event that can also lead to sudden death, but it is more focused on the heart's physical condition rather than the overall outcome of unexpected death. Thus, "sudden death" is the most precise term for this scenario.
