Myocardial performance index and cardiovascular diseases

The Myocardial Performance Index (MPI), also known as the Tei Index, is a measure of the overall performance of the heart that takes into account both systolic and diastolic function. It is a non-invasive echocardiographic index that provides information about the efficiency of the heart's pumping action. The MPI is a useful tool for evaluating cardiac function in various clinical conditions, such as heart failure, myocardial infarction, and cardiomyopathy. A higher MPI value indicates poorer cardiac function, while a lower MPI value indicates better cardiac function. This review will give a summary of the relevant MPI literature, provide a methodology and technical aspects, and make research recommendations.
