LAD widow maker
Also written as: LAD — left anterior descending
Colloquial term for proximal left anterior descending artery occlusion causing extensive anterior wall myocardial infarction with high mortality risk.
Full Definition
The term "LAD widow maker" refers to acute occlusion of the proximal left anterior descending coronary artery, which supplies a large portion of the left ventricular myocardium. This type of occlusion can cause massive anterior wall myocardial infarction, potentially leading to cardiogenic shock, ventricular arrhythmias, and death. The colloquial name reflects the historically high mortality associated with this presentation. Emergency recognition and rapid intervention are critical, as the large amount of myocardium at risk makes these patients particularly vulnerable to sudden cardiac death and mechanical complications.
Usage
Usage note: Use clinical terminology in formal documentation rather than colloquial expressions.
