Abstract
Noninvasive methods in cardiology have progressed very rapidly in recent years. Cardiac catheterization and angiocardiography are the standard methods for evaluating of cardiac performance, however, they need expensive apparatus and are time-consuming, arduous procedures which do not permit to repeat frequently, and sometimes risky. In this article, the indices of pump and muscle function of the heart obtained by invasive methods were compared to those indices obtained by noninvasive methods, and correlation between two groups and usefulness and limitation were discussed. Systolic time intervals are convenient and repeatable measures of left ventricular performance in clinical cardiology. There are significant correlations of PEP/LVET with stroke volume, ejection fraction and mean circumferential shortening velocity. Although some limitations are present in application of this method to certain diseases, these measures are useful in the evaluation of left ventricular performance. Echocardiography has made an era of the noninvasive cardiology. Left ventricular volume, ejection fraction, mean circumferential shortening velocity and PSP/ESVI are accurately calculated by echocardiographic measurement. Nuclear cardiology is also accurate noninvasive method in evaluation of cardiac performance. With this tremendous growth in this field, it will make next era of noninvasive cardiology.
