Introduction. Several cardiovascular manifestations in patients with diabetes may be asymptomatic. Left ventricular diastolic dysfunction (LVDD) is considered to be the earliest metabolic myocardial lesion in these patients, and can be diagnosed with tissue Doppler echocardiography. Silent myocardial ischemia (SMI) is a characteristic and frequently described form of ischemic heart disease in patients with diabetes. Objective. The aim of the study was to assess the prevalence of LVDD and SMI in patients with type 2 diabetes, as well as to compare demographic, clinical, and metabolic data among defined groups (patients with LVDD, patients with SMI and patients with type 2 diabetes, without LVDD and SMI). Methods. We investigated 104 type 2 diabetic patients (mean age 55.4?9.1 years, 64.4% males) with normal blood pressure, prehypertension and arterial hypertension stage I. Study design included basic laboratory assessment and cardiological workup (transthoracic echocardiography and tissue Doppler, as well as the exercise stress echocardiography). Results. LVDD was diagnosed in twelve patients (11.5%), while SMI was revealed in six patients (5.8%). Less patients with LVDD were using metformin, in comparison to other two groups (?2 =12.152; p=0.002). Values of HDL cholesterol (F=4.515; p=0.013) and apolipoprotein A1 (F=5.128; p= 0.008) were significantly higher in patients with LVDD. Conclusion. The study confirmed asymptomatic cardiovascular complications in 17.3% patients with type 2 diabetes.

Background: Diastolic dysfunction in patients suffering from diabetes mellitus represents an earlier stage in the natural history of cardiomyopathy. This study was done to assess the left ventricular diastolic dysfunction in recently diagnosed (<5yr) Type 2 Diabetes Mellitus by Echocardiography and also to determine association of glycemic status (by HBA1c levels) with left ventricular diastolic dysfunction (LVDD).Methods: An observational descriptive study involving 100 diabetic patients, taken on first come first serve basis after applying inclusion and exclusion criteria. In all the subjects, other than routine investigations, HbA1c was estimated and echocardiography was done to evaluate LVDD.Results: Mean value of HbA1c in the study was 8.31+ 1.408 %. 63 out of 100 subjects had LVDD. There was significant positive correlation between HbA1c and LVDD (p value <0.001). As HbA1c increased, severity of LVDD increased. In this study, as BMI increased, HbA1c and LVDD increased & both findings were statistically significant (p value =0.001).Conclusion: Our study indicates that myocardial damage in patients with diabetes affects diastolic function before systolic function &higher HbA1C level is strongly associated with presence of LVDD. Patients should be advised strict control of diabetes in order to reduce the risk for developing LVDD which is a precursor for more advanced disease.Keywords: Diabetes mellitus, Diastolic dysfunction, BMI, HbA1c

Background: Diastolic heart failure occurs due to impaired myocardial relaxation and compliance. Of late, it has been suggested that the changes in the diastolic function occurs before the onset of diabetes, and present in the prediabetic patients. It is also said to be associated with insulin resistance.Methods: This observational study was performed on 50 diabetic patients, with asymptomatic type 2 diabetes. who came in for 2 D echocardiogram with suspected diastolic dysfunction.Results: The mean age among the 50 patients in the study was 54.1±10.99 years and in controls it was 49.56±10.63 years. The fasting sugar among the patients was 179.43±41.57 mg/dl and the post prandial was 236.72±76.24, and it was in the normal range in the controls. The HbA1c was 9.93±1.2 among the patients and 6.09 ± 0.34 in the controls. In the patients, the E/A ratio was 0.83±0.09 compared to 1.22±0.31 of the controls, which was highly significant as the E/e ratio which was 15.1±3.4 and 7.3±0.08 respectively.Conclusions: There was a higher prevalence of diastolic dysfunction among the patients with diabetes in our study. There was no relation of age or gender among the diabetic and the controls, while a strong association and indicators seem to be FBS, PLBS and HbA1c.

In-depth understanding of early cardiovascular manifestations in diabetes is high on international research and prevention agendas given that cardiovascular events are the leading cause of death for diabetic patients. Our aim was to review recent developments in the echocardiographic assessment of left ventricular diastolic dysfunction (LVDD) as a telltale pre-clinical disturbance preceding diabetic cardiomyopathy. We analyzed papers in which patients had been comprehensively assessed echocardiographically according to the latest LVDD guidelines (2016), and those affording comparisons with previous, widely used recommendations (2009). We found that the updated algorithm for LVDD is more effective in predicting adverse cardiovascular events in patients with established LVDD, and less specific in grading other patients (labelled “indeterminate”). This may prove instrumental for recruiting “indeterminate” LVDD cases among patients with type 2 diabetes mellitus (T2DM) in future screening programs. As an interesting consideration, the elevated values of the index E/e’ can point to early diastolic impairment, foretelling diabetic cardiomyopathy. Identifying subclinical signs early makes clinical sense, but the complex nature of T2DM calls for further research. Specifically, longitudinal studies on rigorously selected cohorts of diabetic patients are needed to better understand and predict the subtle, slow onset of cardiac manifestations with T2DM as a complicating backdrop.
