Why the study?
Abnormal glucose metabolism is associated with abnormal LV geometry independent of atherosclerosis, prompting the need to assess LV geometry in normotensive type II diabetic patients.
Is normotensive type II diabetes associated with abnormal left ventricular geometry compared to healthy controls?
Is normotensive type II diabetes associated with abnormal left ventricular geometry compared to healthy controls?
Abnormal left ventricular geometry is highly prevalent in normotensive type II diabetic patients compared to healthy controls, suggesting subclinical target organ damage independent of hypertension.

Suggests subclinical cardiac damage in normotensive diabetes; hypothesis-generating and requires prospective validation before screening implications.
Background: Abnormalities of glucose metabolism are associated with abnormal left ventricular geometry (LV) independent of atherosclerosis. Abnormal LV geometry, a predictor of premature cardiovascular events, indicates presence of subclinical target organ damages. Screening for abnormal LV geometry in diseases of abnormal glucose metabolism is desirable as part of their management protocol. Aim: To assess the left ventricular geometry in normotensive type II diabetic patients. Cross-sectional, descriptive, hospital-based study. One hundred normotensive type II diabetic patients drawn from the Endocrinology and Family Medicine Clinics of a tertiary hospital were age- and gender-matched with 100 apparently healthy controls. Participants meeting the criteria and informed consent proceeded for clinical evaluation, biochemical assessment, electrocardiography, and echocardiography using the American Society of Echocardiography guideline. Materials and Methods: Data were analyzed using the Statistical Package for Social Sciences [SPSS] version 25.0 (Chicago Illinois, USA). Results: Mean age of study and control groups was (55.56 ± 9.89 versus 55.47 ± 10.7) years (χ2 = 0.062, P = 0.951). The mean duration of diabetes illness was 6.57 ± 6.26 years. Prevalence of abnormal LV geometry was 51% (study) versus 18% (control) FT, P < 0.001). Concentric remodeling was the predominant geometry in 36% of study versus 11% of controls, followed by eccentric hypertrophy in 11% (study) versus 4% (control) and concentric hypertrophy in 4% (study) versus 3% (control). Geometry was normal in 49% of study against 82% in the controls (FT, P < 0.001). Significant association existed between LV geometry and duration of diabetes (χ2 = 10.793, P = 0.005). Conclusion: Abnormal LV geometry is highly prevalent in normotensive diabetic patients.
