Background: Patients diagnosed with hypertension will deteriorate into hypertensive heart disease which is characterized by diastolic dysfunction first followed by systolic dysfunction later in the course of the disease. Diastolic dysfunction of the left ventricle causes an increase in LVEDP as well as in the dimension of the left atrium. P-Wave Terminal Force V1 (PTFV1) which is derived from 12 lead ECG could help diagnose diastolic dysfunction in centers where echocardiography is not available. The purpose of this study was to determine the correlation of PTFV1 on the 12-lead Electrocardiography with diastolic dysfunction in patients diagnosed with hypertension in the outpatient clinic of Cardiac Center Adam Malik General Hospital in Medan. Methods: This is a cross-sectional study conducted from March 2019 until August 2019. Patients with hypertension who met the inclusion criteria were examined electrocardiographically to obtain PTFV1 value. Then echocardiography examination was then performed to assess the grades of diastolic dysfunction and other parameters. Analysis of correlation between PTFV1 values and diastolic dysfunction was then conducted. Results: From the clinical characteristics, there is no difference regarding age, sex , and risk factorsbetween the three diastolic dysfunction groups, while echocardiography characteristic shows more reduced EF in grade III diastolic dysfunction (36.5±7.7). Significant differences in PTFV1 are found among diastolic dysfunction groups. Grade I diastolic dysfunction has PTFV1 value of 23.8 mm.ms, grade II diastolic dysfunction has PTFV1 value of 34.1 mm.ms, and grade III diastolic dysfunction has PTFV1 value of 52.1 mm.ms, Significance of  p value is <0.001. There is a strong correlation between PTFV1 and diastolic dysfunction grade (r = 0.63 (P <0.001)). Cut off point of PTFV1 > 29.8 mm.ms can discriminate patients who have increased LAP with a sensitivity of 84% and specificity of 71%. Conclusions: PTFV1 is a simple screening tool which is widely available and correlate well with left ventricular diastolic dysfunction in patients with hypertension, which makes it a good alternative tool especially in areas where echocardiography is not readily available.

Abstract Objective: Mounting evidence links cirrhosis patients with left ventricular diastolic dysfunction(LVDD) has a poor prognosis. However, little is known about these particular individuals. Therefore, we conducted this cross-sectional study to assess the prevalence of LVDD and its associated risk factors.Methods: Consecutive cirrhosis patient who were attending Hangzhou Xixi hospital from January 2018 to December 2019 were included in this study. According to the American Society of Echocardiography 2016 criteria, cirrhosis patients were sorted into two group: the left ventricular diastolic dysfunction(LVDD) group and left ventricular diastolic function normal(LVDDn) group. Patients’ demographic data, clinical characteristics, laboratory data were recorded. Furthermore, we conducted a multi-factor analysis.Results: A total of 398cirrhosis patients were included in the study. The incidence of LVDD in this study was 49.7% (198 cases). In this study, the mean age and BMI of the patients were 52.9±8.2 years and 23.0±3.3kg/m2,respectively. Of 398 patients, 255(64.1%) of them were males. With regard to etiology, there were 296 patients (74.4%) with hepatitis B cirrhosis and 59 patients (14.8%) with alcoholic cirrhosis. The LVDD group had higher age, higher BMI, greater frequency of ascites and esophageal varices, prolonged prothrombin time, increased international normalized ratio, increased bilirubin, increased CK and AST, and longer QT interval than the LVDDn group(p<0.05, both). In terms of echocardiography, the LVDD group had larger aortic inner diameter, left atrial inner diameter and left ventricular wall diastolic thickness than LVDDn group(p<0.05, both). The multivariate analysis showed age>55 years, BMI>24kg/m2, hepatic decompensated, QTcB>440ms were independently associated with risk of LVDD.Conclusion: The prevalence of LVDD among cirrhosis patients was 49.8%. Cirrhosis patients with LVDD had worse liver function. Further, age>55 years, BMI>24kg/m2, hepatic decompensated, QTcB>440ms were independent predictors of LVDD.

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

Abstract Background: Left ventricular diastolic dysfunction (LVDD) is a recognized complication of diabetes mellitus which precedes and is a risk factor for heart failure. We aimed to determine the prevalence of LVDD and its association with body mass index (BMI) in ambulatory adults with diabetes mellitus. Methods: We conducted a cross-sectional study of 195 ambulatory Ugandan adults living with diabetes mellitus for at least five years from the time of diagnosis at Mbarara Regional Referral Hospital (MRRH). We collected demographic, clinical data and measured body mass index. Laboratory tests included glycated hemoglobin (HbA1c), low-density lipoprotein (LDL), and urine microalbumin. Echocardiography was done to determine LVDD by assessing the mitral inflow E/A ratio, E/è ratio, TR jet peak velocity, and left atrium maximum volume index. Logistic regression was used to establish associations of body mass index and other covariates with LVDD. Results: Overall, 195 participants were enrolled and 141(72.3%) were females. The mean age was 62 [standard deviation (SD), 11.5] years and median duration of diabetes diagnosis was 10 [Interquartile range (IQR), 7,15] years. LVDD was prevalent at 86% and majority, 127(65.13%) had grade-1 diastolic dysfunction. BMI ≥25kg/m2 [adjusted Odds Ratio (aOR)=2.8, (95% confidence interval (CI)=1-7.6), p=0.038], age 50 year or more [aOR= 4.9, (95%CI=1.5-16.2), p=0.010], and history of hypertension [aOR= 3.0, (95% CI= 1.1-8.1), p=0.031] were associated with LVDD.Conclusion: The prevalence of LVDD was high during the study period. We recommend early and periodic echocardiographic screening for diabetes patients with high body mass index.

Diabetes mellitus, a disease that has been reaching epidemic proportions, is an important risk factor to the development of cardiovascular complication. Diabetes causes changes within the cardiac structure and function, even in the absence of atherosclerotic disease. The left ventricular diastolic dysfunction (VE) represents the earliest pre-clinical manifestation of diabetic cardiomyopathy, preceding the systolic dysfunction and being able to evolve to symptomatic heart failure. The doppler echocardiography has emerged as an important noninvasive diagnostic tool, providing reliable data in the stages of diastolic function, as well as for systolic function. With the advent of recent echocardiographic techniques, such as tissue Doppler and color M-mode, the accuracy in identifying the moderate diastolic dysfunction, the pseudonormal pattern, has significantly improved. Due to cardiometabolic repercussions of DM, a detailed evaluation of cardiovascular function in diabetic patients is important, and some alterations may be seen even in patients with gestational diabetes.
