Proportion of Diagonal Ear Lobe Crease and its Association With Sudden Death Due to Coronary Artery Disease- An Autopsy Study
Keywords:diagonal ear lobe crease, coronary artery disease, sudden death, extra cardiovascular physical predictors.
Coronary artery disease has been a number one killer worldwide and in India it has increased phenomenally
as the most important cause of sudden natural death of cardiac aetiology in the last few decades. Changing
lifestyles, stress, habits, presence of other predisposing pathologies etc have played direct as well as indirect
roles in its causation. Conventionally the predictors for coronary artery disease have been predominantly
risk factors. Notwithstanding this, of recently a number of extra cardio vascular physical parameters like ear
lobe crease have shown a reasonably promising trend in predicting the presence of coronary artery disease
thereby enabling prompt intervention which in turn can reduce cardiac mortality in the long run. The present
study focuses on this aspect of detecting an association between diagonal ear lobe crease and sudden death
due to coronary artery disease. A total of 188 cases brought for medicolegal autopsy was studied. It has been
revealed that diagonal ear lobe crease detected at autopsy has a statistically significant association with both
the presence of coronary artery disease as well as the severity of atheromatous occlusion in sudden deaths.
Hence diagonal ear lobe crease can have a reasonable predictive value in detecting coronary artery disease
that could be used for the early detection of individuals with coronary artery disease and thus pave the way
for early interventional strategies.
