Objective: to evaluate the diagnostic significance of the electrocardiographic (ECG) criteria for left ventricular hypertrophy (LVH) in 12 leads in patients with essential arterial hypertension (AH) and in AH in combination with ischemic heart disease (IHD) compared with echocardiography (EchoCG) data. Materials and methods: ECG and EchoCG were carried out in 165 patients with AH (n = 139) and AH with concommitant IHD (n=26). Results: EchoCG signs of LVH ("EchoCG +") were detected in 72 (51,7%) patients with AH and in 12 (46,1 %) patients in AH + IHD. In the EchoCG + group the electrocardiographic signs of LVH (Sokolov-Lyon index, Cornell product, Cornell index) were determined in 37 (30,5 %) hypertensive patients and in no case in the AH + IHD group. In the "EchoCG-" group, electrocardiographic signs of LVH were determined in 8 hypertensive patients and two in the AH + CHD group. The use of additional voltage criteria for LVH in the frontal plane leads (RI > 15 mm, R I + S III > 25 mm, R aVL > 12 mm) increased the detection of LVH from 30,5 % (n=22) to 51,3 % (n=37). The false negative ECG diagnosis of LVH was influenced by: positional features, interventricular conduction defect, metabolic disorders and high index body mass. Conclusion: The Sokolov-Lyon index, the Cornell index, the Cornell product have low sensitivity in the diagnosis of LVH (30,5 %). Adding the frontal plane leads voltage criteria for LVH may contribute to increase in electocardiographic LVH detection (51,3 %). The decrease in the sensitivity of the ECG criteria for LVH is mainly caused by the positional features of the heart, interventricular conduction defect, metabolic disorders and high index body mass.

Abstract BACKGROUND Performance of electrocardiographic (ECG) criteria for echocardiographically diagnosed left ventricular hypertrophy (LVH) in Chinese hypertensive patients is not well known. We investigated the accuracy of various ECG criteria for the diagnosis of the echocardiographic LVH according to the new cutoff values of left ventricular mass (LVM) index (>115 g/m2 for men and >95 g/m2 for women) in Chinese hypertensive patients. METHODS Our study included 702 consecutive hypertensive inpatients including 92 (13.1%) concentric and 121 (17.2%) eccentric LVH on standard echocardiography. Diagnostic accuracy of 7 ECG criteria was evaluated by calculating sensitivity and specificity and by using the receiver operating characteristic curves. RESULTS The ECG criteria for the detection of the echocardiographically defined LVH had a sensitivity of 15%–31.9% and specificity of 91.6%–99.2% overall, 20.7%–43.5% and 91.6%–99.2% concentric, and 7.4%–23.1% and 91.6%–99.2% eccentric. ECG diagnosis of LVH defined as the positive diagnosis of any of 4 ECG criteria including Sokolow–Lyon voltage, Cornell voltage, Cornell product, and RavL voltage had a sensitivity of 54% and specificity of 86.3% overall, 71.7% and 86.3% concentric, and 40.5% and 86.3% eccentric. After adjustment for confounding factors, various ECG criteria were significantly correlated with LVM, with standardized β coefficients from 0.20 to 0.39 (P < 0.001) and the highest coefficient for the Cornell product criterion. CONCLUSIONS All ECG LVH indexes had low sensitivity and high specificity in Chinese hypertensive patients. Combination of 4 or all ECG criteria might improve sensitivity without any loss of specificity.

Abstract Background Circulating monocytes and tissue macrophages play complex roles in the pathogenesis of hypertension and the resulting target organ damage. In this study, we observed alterations in the monocyte phenotype and inflammatory state of hypertensive patients with left ventricular hypertrophy (LVH) and studied the effects of irbesartan in these patients. This study might reveal a novel mechanism by which irbesartan alleviates LVH, and it could provide new targets for the prevention and treatment of hypertensive target organ damage. Methods CD163 and CD206 expression on monocytes and IL-10 and TNF-α levels in the serum of hypertensive patients with or without LVH and of healthy volunteers were detected. Furthermore, we treated monocytes from the LVH group with different concentrations of irbesartan, and then, CD163, CD206, IL-10 and TNF-α expression was detected. Results We found, for the first time, that the expression of CD163, CD206 and IL-10 in the LVH group was lower than that in the non-LVH group and healthy control group, but the TNF-α level in the LVH group was significantly higher. Irbesartan upregulated the expression of CD163 and CD206 in hypertensive patients with LVH in a concentration-dependent manner. Irbesartan also increased the expression of IL-10 and inhibited the expression of TNF-α in monocyte culture supernatants in a concentration-dependent manner. Conclusions Our data suggest that inflammation was activated in hypertensive patients with LVH and that the monocyte phenotype was mainly proinflammatory. The expression of proinflammatory factors increased while the expression of anti-inflammatory factors decreased. Irbesartan could alter the monocyte phenotype and inflammatory status in hypertensive patients with LVH. This previously unknown mechanism may explain how irbesartan alleviates LVH.

Abstract Background Left Ventricular Hypertrophy (LVH) is an independent predictor of mortality and cardiovascular morbidity and the 12-lead ECG is recommended as a universal screening for patients with hypertension. However, the ECG has low sensitivity and there is limited data in patients 70 years or older. The recently published Peguero-Lo Presti (PLP) criteria had improved accuracy compared with other ECG criteria but with very few patients with age ≥70 years included. Purpose To compare the accuracy of the PLP criteria versus the traditional ECG criteria for detecting LVH in patients ≥70 years. Methods Retrospective single-center study. Patients were included if they were 70 years or older and underwent an ECG and echocardiogram (gold standard) less than 180 days apart from jan/2017 to mar/2018. Patients with left or right bundle branch block, non-sinus rhythm or ventricular paced rhythm were excluded. All tracings were independently reviewed by two cardiologists, blinded to the echocardiogram. The PLP criteria was compared against Cornell voltage (CV), Sokolow-Lyon voltage (SL), and Romhilt-Estes 4 and 5 (RE) criteria. LVH was defined as a left ventricular mass index >115 g/m2 in males and >95 g/m2 in females, according to the echocardiogram. McNemar's test, F1 score, and the area under the Receiver Operating Characteristic curves (AUC) were used to compare the diagnostic performance of the tests Results A total of 592 patients were included (mean age 77.5 years, SD: 5.9; 50.8% were women). The PLP criteria had increased sensitivity compared with both the SL and CV criteria (p<0.0001 for both comparisons) and RE5 (p=0.042). PLP also had better specificity than the RE4 criteria (p<0.0001) and the highest F1 accuracy score (Table 1). The AUC of the PLP was significantly higher than the AUC of the CV and RE criteria (0.70 vs 0.66 vs 0.64, respectively, p<0.05) and numerically higher than the SL criteria (AUC=0.67, p=0.311, Figure 1). Conclusion Compared to the traditional ECG criteria for LVH, the PLP criteria had the highest diagnostic accuracy in elderly patients. Figure 1.

Abstract Background Conflicting information exists regarding the association between insulin resistance (IR) and left ventricular hypertrophy (LVH). We described the associations between obesity, fasting insulinemia, homeostasis model assessment of insulin resistance (HOMA-IR), and LVH in Black patients with essential hypertension. Methods A case–control study was conducted at the Centre Médical de Kinshasa (CMK), the Democratic Republic of the Congo, between January and December 2019. Cases and controls were hypertensive patients with and without LVH, respectively. The relationships between obesity indices, physical inactivity, glucose metabolism and lipid disorder parameters, and LVH were assessed using linear and logistic regression analyses in simple and univariate exploratory analyses, respectively. When differences were observed between LVH and independent variables, the effects of potential confounders were studied through the use of multiple linear regression and in conditional logistic regression in multivariate analyses. The coefficients of determination (R2), adjusted odds ratios (aORs), and their 95% confidence intervals (95% CIs) were calculated to determine associations between LVH and the independent variables. Results Eighty-eight LVH cases (52 men) were compared against 132 controls (81 men). Variation in left ventricular mass (LVM) could be predicted by the following variables: age (19%), duration of hypertension (31.3%), body mass index (BMI, 44.4%), waist circumference (WC, 42.5%), glycemia (20%), insulinemia (44.8%), and HOMA-IR (43.7%). Hypertension duration, BMI, insulinemia, and HOMA-IR explained 68.3% of LVM variability in the multiple linear regression analysis. In the logistic regression model, obesity increased the risk of LVH by threefold [aOR 2.8; 95% CI (1.06–7.4); p = 0.038], and IR increased the risk of LVH by eightfold [aOR 8.4; 95 (3.7–15.7); p < 0.001]. Conclusion Obesity and IR appear to be the primary predictors of LVH in Black sub-Saharan African hypertensive patients. The comprehensive management of cardiovascular risk factors should be emphasized, with particular attention paid to obesity and IR. A prospective population-based study of Black sub-Saharan individuals that includes the use of serial imaging remains essential to better understand subclinical LV deterioration over time and to confirm the role played by IR in Black sub-Saharan individuals with hypertension.
