Key result
T2D duration ≥10 years is linked to ~13% lower LVEF in asymptomatic normotensive patients.
Why the study?
Echocardiography is universally available and economical for detecting early LV systolic dysfunction, and the study aimed to evaluate cardiac systolic function and its correlation with disease duration in normotensive, asymptomatic type 2 diabetic patients.
Does duration of diabetes correlate with reduced cardiac systolic function evaluated by 2D-echocardiography in asymptomatic, normotensive type 2 diabetic patients?
Cross-Sectional (n=50)
No
Does duration of diabetes correlate with reduced cardiac systolic function evaluated by 2D-echocardiography in asymptomatic, normotensive type 2 diabetic patients?
Longer duration of type 2 diabetes is positively correlated with subclinical reduction in cardiac systolic function in asymptomatic, normotensive patients.

May support duration-stratified LVEF monitoring; leaves open need for longitudinal validation before practice change.
Echocardiography is a universally availabe and economical test for detecting early LV systolic dysfunction in normotensive and asymptomatic type 2 diabetic patients. This is a cross sectional study of such patients evaluating cardiac systolic function using 2D-Echocardiography. Ejection fraction and Fractional shortening are the two most sensitive indicators of it. Only 18% of patients had decreased LVEf and 6% showed reduced fractional shortening . Although longer duration of diabetes was positively correlated with reduction in systolic functioning of heart. Early identification of subclinical signs of heart failure by these noninvasive and less expensive methods may improve outcomes in type 2 diabetes patients.

Kumar et al. (2021) conducted a cross-sectional in Asymptomatic Type 2 Diabetes Mellitus (n=50). Diabetes duration ≥10 years vs. Diabetes duration <10 years was evaluated on Mean Left Ventricular Ejection Fraction (LVEf) (p=0.0001). In asymptomatic normotensive type 2 diabetes patients, a disease duration of ≥10 years significantly reduced mean left ventricular ejection fraction compared to <10 years (59% vs 72%, p=0.0001).
