Traditionally, performing conventional echocardiography for detecting ischemia-related systolic abnormalities involves visually estimating the changes of wall thickening in circular muscle. This has well-documented limitations for both the interobserver variability and the ability of the human eye to resolve rapid, short-lived motion. Another approach to defining the regional myocardial properties could be to evaluate the deformation of a myocardial segment during the cardiac cycle. During the cardiac cycle, regional deformation of the myocardium occurs in 3 major directions: longitudinally; circumferentially; and radially. Currently, the terms “myocardial strain rate” and “strain” are used as indexes of longitudinal myocardial deformation. The physical definition of strain is the relative change in length of a material related to its original length. Regional strain rate and strain are derivative of myocardial velocities. The actual sequence of the regional changes in the myocardial function that are induced by acute ischemia has been well defined by experimental sonomicrometric techniques. Acute ischemia induces a delay in the onset of contraction, a progressive decrease in the rate and degree of thickening, and a progressive delay in the timing of the peak thickening until this event occurs in what is early diastole for the surrounding nonischemic myocardial segments. Finally, systolic thickening is virtually or completely abolished by total occlusion, and only late systolic/early diastolic thinning occurs. Although it has been well documented in the animal laboratory setting, all the components of the above ischemic response have yet to be well documented in the clinical setting by noninvasive imaging techniques.

Accordingly, adults with type 2 DM are susceptible for heart failure and a lot of experimental studies have shown significant changes in microvasculature and myocardial interstitial fibrosis in type 2 DM. Therefore, early recognition of subclinical myocardial dysfunction and therapeutic intervention such as renin-angiotensin-aldosterone system blockers may prevent the progression of heart failure in diabetic patients. Although there have been many studies regarding diabetic cardiomyopathy in adults with type 2 DM, adults subjects innately have confounding factors for subclinical myocardial dysfunction. Aging, coronary artery disease, hypertension and long-standing metabolic properties related to insulin resistance also influence on left ventricular (LV) mechanical function. In this issue of the Journal, Abd-El Aziz et al. report the results of their study of forty patients with type 1 DM and fortytwo healthy controls between 6 and 16 years. In this study, the interrogators demonstrated that diabetic children have evidence of LV and right ventricular dysfunction on tissue Doppler echocardiographic assessment. Children with type 1 DM usually have fewer confounders of myocardial dysfunction than adults with type 2 DM. In fact, only one patient in this study subjects had blood pressure above 95th percentile. We can simply accept that myocardial dysfunction in diabetic children is mainly caused by DM itself. This is one of the strengths of this study. However, in the interpretation of the present study, main results should be cautiously understood. First, in terms of LV diastolic function, E’ velocity and E/E’ were not different between diabetic children and controls.
