Implication

May prompt ECG timing relative to meals to avoid misdiagnosis; hypothesis-generating and requires prospective confirmation before practice change.

Key Points

To evaluate the occurrence of transient electrocardiographic T-wave inversion after eating and assess the risk of incorrectly diagnosing coronary artery disease.
Reviewed 4 clinical cases misdiagnosed with coronary artery disease due to T-wave flattening or inversion in bipolar or lateral V leads.
Evaluated postprandial T-wave responses following a high-carbohydrate meal in 85 normal young adults and 47 patients.
Observed that postprandial T-wave flattening and inversion were temporary phenomena directly inducible by high-carbohydrate meals.
Demonstrated that benign postprandial T-wave changes occur across healthy cohorts and clinical populations, mimicking ischemic heart disease patterns.

Structured PICO

Does a high-carbohydrate meal cause temporary T-wave changes on electrocardiogram that mimic coronary artery disease?

Population

136 individuals, comprising 4 patients misdiagnosed with coronary artery disease due to T-wave changes, 85 normal young adults, and 47 other patients.

Intervention

High-carbohydrate meal

Outcome

T-wave changes (flattening or inversion in bipolar or lateral V leads) on electrocardiogramsurrogate

Postprandial T-wave inversion after a high-carbohydrate meal can mimic ischemic ECG changes and lead to misdiagnosis of coronary artery disease.
