The present research addresses left ventricular hypertrophy (LVH) frequency by voltage criteria in male population (representatives of native-born population and non-residents) with verified coronary atherosclerosis in Yakutia. Design and methods. Electrocardiography (ECG) analysis of LVH voltage criteria in patients with verified coronary atherosclerosis was carried out. ECG was analyzed in age-matched male groups - native-born (n = 200) and non-residents (n = 174). LVH criteria included the following measurements: RaVL > 11 mm, RV5(V6) ≥ 27 mm, Sokolow-Lyon voltage > 35 mm, Cornell voltage criteria > 28 mm for men, Cornell voltage duration product > 2440 mm/ms and Gubner-Ungerleider voltage > 25 mm. Results. The following ECG criteria of LVH are more often identified in Yakut inhabitants with verified coronary atherosclerosis: Cornell voltage duration product, RaVL > 11 mm, Cornell voltage criteria and Sokolow-Lyon criteria, more rarely RV5 (≥ 27 mm and Gubner-Ungerleider voltage criteria). LVH with one ore more voltage criteria was defined in 42,8 % of cases, more often among native-born population as compared to non-residents. Conclusion. Therefore, LVH by voltage criteria is defined more often in native-born population in Yakutia. Arterial hypertension is one of the underlying causes leading to LVH.

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.

Design And Methods

Objective. To estimate the changes of voltage electrocardiographic criteria of the left ventricular hypertrophy in arterial hypertension in subjects of different gender. Design and methods. The study included 94 hypertensive patients (55 males, 39 females). Mean age was 51 ± 6 years. Based on gender and the presence of left ventricular hypertrophy patients were divided into four groups. Results. There were significant differences of indices of Sokolow-Lyon and Cornell in males with I and II stages of arterial hypertension (р = 0,012 and р = 0,017, respectively). The same differences were found in females with I and II stages of arterial hypertension (р = 0,037 and р = 0,001, respectively). Specificity was 92 % for both indices, and the sensitivity was 26 % for Sokolow-Lyon index, and 39 % for Cornell index. In women sensitivity was 0 and 72 % for Sokolow-Lyon and Cornell indices, respectively, and specificity was more than 90 % for both criteria. Conclusion. Gender differences should be considered when voltage electrocardiographic criteria of the left ventricular hypertrophy are assessed in hypertensive patients.

Abstract Background Cornell voltage criteria (CL) and Sokolow-Lyon criteria (SL) for electrocardiographic left ventricular hypertrophy (ECG-LVH) are well known predictors of cardiovascular outcome. However, their predictive value may differ according to patient type and remains to be further tested in diabetic mellitus (DM) patients. Purpose The present study aims to determine the prevalence of each ECG-LVH criteria and their respective predictive value in DM patients. Method A retrospective cohort study of individuals age >40 years with digital ECGs from primary care were collected during 2001 to 2011. Data on medication, comorbidity, and outcomes were collected from Danish nationwide registries. DM was defined if individuals were prescribed oral antidiabetics or insulin, if they were diagnosed with DM type I or II, or had a HbA1c>48 mmol/l. Cox multivariable analysis was used for estimating hazard ratio (HR) and 95% confidence intervals (95% CI) for all-cause mortality during follow-up of up to 17 years. Results Included were 183,749 individuals with a digital ECG collected in primary care. A total of 13,003 (7.1%) individuals had DM, they were older (65.8 vs. 61.3 years), had more myocardial infarction (16.1% vs. 5.2%), stroke (14.4% vs. 6.2%), hypertension (35.1% vs. 13.2%), CL LVH (8.0% vs. 5.6%) and more were males (53.3% vs. 45.3%) compared to the non-DM individuals (all p<0.001). CL identified a larger percentage of LVH in DM compared to non-DM individuals (8.0% vs. 5.6%, p<0.001), whereas SL identified similar percentage LVH in DM and non-DM individuals (8.5% vs. 8.1%, p=0.068). In multivariable adjusted analysis CL LVH remained strongly associated with all-cause mortality [HR 1.45 (95% CI: 1.42–1.48)] compared to SL LVH which found only a modest association [HR 1.06 (95% CI: 1.03–1.10)] (Figure 1). Of note, the association of CL LVH and all-cause mortality was even stronger than DM per se. There was no interaction with DM and either ECG LVH criteria (p>0.45). Conclusion Cornell Voltage Left Ventricular Hypertrophy is a strong predictor of mortality in patients with and without diabetes and an independent risk factor compared to hypertension and diabetes. The predictive value was substantially stronger than Sokolow-Lyon Voltage criteria for hypertrophy. Figure 1. LVH and all-cause mortality Funding Acknowledgement Type of funding source: None

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.

The aim of the study was to assess the relationship between serum selenium and zinc concentrations (Se-S and Zn-S) and the left ventricle geometry in patients suffering from arterial hypertension. A total of 78 people with arterial hypertension (mean age: 53.72 ± 12.74 years) participated in the study. Se-S and Zn-S were determined in all patients. The type of left ventricular remodelling and hypertrophy was determined by the left ventricular mass index (LVMI) and relative wall thickness (RWT) measured by echocardiography. Se-S and Zn-S in the whole group were 89.84 ± 18.75 µg/L and 0.86 ± 0.13 mg/L. Normal left ventricular geometry was found in 28.2% of patients; left ventricular hypertrophy (LVH) in 71.8%, including concentric remodelling in 28.2%, concentric hypertrophy in 29.5%, and eccentric hypertrophy in 14.1%. LVH was statistically significantly more frequent in patients with Se-S < median compared to patients with Se-S ≥ median (87.2% vs. 56.4%, p < 0.05), as well as in patients with Zn-S < median compared to patients with Zn-S ≥ median (83.8% vs. 60.9%, p < 0.05). In hypertensive patients, older age, higher LDL cholesterol, higher fasting glucose, lower Se-S, and lower Zn-S were independently associated with LVH. In conclusion, in hypertensive patients, left ventricular hypertrophy may be associated with low levels of selenium and zinc in the serum.
