Abstract:
Introduction. Left ventricular hypertrophy is defined as an increase in the left ventricular mass. Electrocardiography is a widely used and cost-effective method for the initial screening of the condition, but it has limited sensitivity and specificity. The Sokolow-Lyon and Cornell criteria are still most commonly used in diagnosing the disease; their sensitivity, however, is low. On the contrary, the Romhilt-Estes scoring system incorporates atrial abnormalities and repolarization phases making this scoring system a better diagnostic tool. This study explores the correlation between electrocardiography and echocardiography in the diagnosis of left ventricular hypertrophy. Material and Methods. The study enrolled 30 patients with median age of 62, diagnosed with arterial hyperten?sion, who underwent a 12-lead electrocardiogram and transthoracic echocardiogram. The analysis included the assessment of correlation between the relevant electrocardiographic parameters and the left ventricular mass index, as well as calculation of their diagnostic capability including the area under the ROC curve. Re?sults. Positive correlation of moderate intensity has been observed between the left ventricular mass index and Sokolow-Lyon (?=0.479), Cornell index (?=0.366), and Cornell product (?=0.423). Cornell product had the highest sensitivity (0.82), while the Romhilt-Estes criteria exhibited the highest specificity (0.85). Sokolow-Lyon yielded the highest area under the curve (0.733), followed by Cornell product (0.640), Cornell voltage (0.622), and Romhilt-Estes criteria (0.570). Conclusion. The Sokolow-Lyon criterion exhibited the best balance between sensitivity and specificity, the highest and significant area under the ROC curve and the strongest correlation with the left ventricular mass index.

Abstract:
Background The Peguero-Lo Presti criteria are novel electrocardiographic (ECG) diagnostic criteria for the detection of left ventricular hypertrophy (LVH) and represent the sum of the amplitude of the deepest S wave in any lead with the S wave in lead V4 (SD+SV4). The diagnostic efficacy of the Peguero-Lo Presti criteria in LVH is still debatable. We aimed to test the sensitivity and specificity of the Peguero-Lo Presti criteria and compared them with those of the Cornell voltage index to assess their overall performance in LVH diagnosis. Methods Electronic databases (e.g., Medline, Web of Knowledge, Embase, and the Cochrane Library) were searched from their inception until May 18, 2020. Trials written in English that investigated the Peguero-Lo Presti criteria for detecting LVH were included. Data were independently extracted and analyzed by two investigators. Results A total of 51 records were screened, and 6 trials comprising 13,564 patients were finally included. A bivariate analysis showed that the sensitivity of the Peguero-Lo Presti criteria (0.52, 95% confidence interval (CI) 0.46–0.58) was higher than that of the Cornell voltage index (0.29, 95% CI 0.23–0.36) and Sokolow-Lyon criteria (0.24, 95% CI 0.21–0.27); the diagnostic accuracy of the Peguero-Lo Presti criteria (0.69, 95% CI 0.65–0.73) was also higher than that of the Cornell voltage index (0.67, 95% CI 0.62–0.71) and Sokolow-Lyon criteria (0.28, 95% CI 0.25–0.32); and the specificity of the Peguero-Lo Presti criteria (0.85, 95% CI 0.79–0.90) was similar to that of the Cornell voltage index (0.92, 95% CI 0.89–0.95) and Sokolow-Lyon criteria (0.94, 95%CI 0.88–0.97). Two trials (including 12,748 patients) were discharged because they included partly healthy subjects and accounted for substantial heterogeneity. Pooled analysis of the remaining 4 trials (including 816 patients) showed that the sensitivity of the Peguero-Lo Presti criteria (0.56, 95% CI 0.51–0.61) was also higher than that of the Cornell voltage index (0.36, 95% CI 0.31–0.42) and Sokolow-Lyon criteria (0.24, 95% CI 0.18–0.31); the diagnostic accuracy of the Peguero-Lo Presti criteria (0.84, 95% CI 0.80–0.87) was also higher than that of the Cornell voltage index (0.54, 95% CI 0.50–0.58) and Sokolow-Lyon criteria (0.38, 95% CI 0.34–0.42); and the specificity of the Peguero-Lo Presti criteria (0.90, 95% CI 0.87–0.92) was similar to that of the Cornell voltage index (0.93, 95% CI 0.88–0.96) and Sokolow-Lyon criteria (0.97, 95% CI 0.90–0.99). Both the likelihood ratio and posttest probability of the Peguero-Lo Presti criteria and Cornell voltage index were moderate. Conclusion Based on this systematic review and meta-analysis, the Peguero-Lo Presti criteria-based ECG diagnostic method for LVH has high sensitivity, specificity and diagnostic accuracy and should be applied in clinical practice settings.

Abstract:
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:
BackgroundLeft ventricular hypertrophy (LVH) is a marker of pediatric hypertension and predicts development of cardiovascular events. Electrocardiography (ECG) screening is used in pediatrics to detect LVH thanks to major accessibility, reproducibility and easy to use compared to transthoracic echocardiography (TTE), that remains the standard technique. Several diseases were previously investigated, but no data exists regarding our study population. The aim of our study was to evaluate the relationship between electrocardiographic and echocardiographic criteria of LVH in normotensive African children.MethodsWe studied 313 children (mean age 7,8 ± 3 yo), in north-Madagascar. They underwent ECG and TTE. Sokolow-Lyon index was calculated to identify ECG-LVH (>35 mm). Left ventricle mass (LVM) with TTE was calculated and indexed by height2.7(LVMI2.7) and weight (LVMIw). We report the prevalence of TTE-LVH using three methods: (1) calculating percentiles age- and sex- specific with values >95th percentile identifying LVH; (2) LVMI2.7>51 g/m2.7; (3) LVMIw>3.4 g/weight.Results40 (13%) children showed LVMI values >95th percentile, 24 children (8%) an LVMI2.7>51 g/m2.7while 19 children (6%) an LVMIw>3.4 g/kg. LVH-ECG by Sokolow-Lyon index was present in five, three and three children respectively, with poor values of sensitivity (ranging from 13 to 16%), positive predictive value (from 11 to 18%) and high values of specificity (up to 92%). The effects of anthropometrics parameters on Sokolow-Lyon were analyzed and showed poor correlation.ConclusionECG is a poor screening test for detecting LVH in children. In clinical practice, TTE remains the only tool to be used to exclude LVH.

Abstract:
INTRODUCTION: Several electrocardiographic (ECG) criteria have previously been suggested to diagnose left ventricular hypertrophy (LVH). Studies on diagnostic performance of each criterion in Asian population were limited and this study was done to determine the diagnostic performance of the six different ECG criteria, including the newly developed Peguero–Lo Presti criterion, in diagnosing LVH in Filipino patients. METHODOLOGY: A single-center retrospective cohort study was conducted. The comparison of ECG to echocardiographic diagnosis of LVH was assessed by Spearman ρ correlation. The area under the curve analysis was used to evaluate discrimination ability of ECG-LVH criteria to identify echocardiography-LVH. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the six criteria were described with 95% confidence interval, with P < 0.05 considered statistically significant. RESULTS: A total of 325 patients were included in the final analysis; 56.61% had LVH, 23.07% of which were both ECG-based and echocardiography-based LVH. The Peguero–Lo Presti criterion had the highest sensitivity (53.1%), a lower specificity (75.5%), and a lower accuracy (68.6%), compared with the other criteria. Sokolow-Lyon index had highest specificity (97.2%) and positive predictive value (75.0%). Cornell voltage had relatively better discriminative performance (area under the curve, 0.73). CONCLUSION: Having a higher sensitivity, the Peguero–Lo Presti criterion can be used as a screening tool for LVH more than the Sokolow-Lyon and Cornell voltage. Cornell voltage criterion has higher correlation with left ventricular mass index and better discriminative ability for the detection of LVH. Further studies with the possibility of combining different ECG criteria are suggested to increase the sensitivity of the ECG criteria.

Abstract:
Introduction. Hypertrophic cardiomyopathy is a disorder of the myocardium characterized by asymmetric or symmetric left ventricular hypertrophy. It is often an inherited disorder with an autosomal dominant pattern. The aim of this study was to evaluate the electrocardiographic characteristics of patients with hypertrophic cardiomyopathy, as well as to assess the accuracy of current electrocardiographic criteria for left ventricular hypertrophy used as indicators of hypertrophic cardiomyopathy. Material and Methods. This retrospective study was conducted using hospital medical records of 42 patients with the diagnosis of hypertrophic cardiomyopathy. Detailed electrocardiography analysis, apart from all the usual parameters, included the calculation of indices used to diagnose left ventricular hypertrophy including Sokolow augmented vector left, Cornell voltage, Cornell product, and Sokolow-Lyon index. Results. Sinus rhythm was present in 95.2% of patients, while atrial fibrillation was found in 4.8%. The majority of patients presented with left axis deviation. A slight positive correlation was found between the Sokolow augmented vector left index and posterolateral wall thickness (r = 0.475; p < 0.05), and also between the Cornell voltage index and posterolateral wall thickness (r = 0.368; p < 0.05). A borderline positive correlation was found between the Cornell product index and posterolateral wall thickness (r = 0.290; p = 0.063). Interventricular septum thickness showed no significant correlation with any of the electrocardiographic indices of left ventricular hypertrophy. Conclusion. In patients with hypertrophic cardiomyopathy, the Sokolow augmented vector left and Cornell voltage indices were the best indicators of posterolateral wall hypertrophy, whereas none of the examined indices correlated well with the interventricular septum thickness.

Abstract:
Background: Arterial hypertension (AHT) is the leading preventable cause of death worldwide. Left ventricular hypertrophy (LVH) is one of the most important prognostic markers in hypertension and a predictor for mortality. The goals of this study were to examine the prevalence of LVH detected by echocardiography in patients with AHT and to describe patients with severe LVH. Methods: This is a retrospective monocentric study including patients treated at a tertiary hypertension clinic. Echocardiographic data were taken from written reports from our hospital’s echocardiography laboratories. We compared patients with severe LVH (septum thickness ≥ 15 mm) with patients with normal left ventricular (LV) geometry and with patients with concentric or eccentric hypertrophy regarding age, gender, comorbidities, medication, duration of hypertension, blood pressure (BP) and ECG changes at time of echocardiography. Results: Twenty-nine patients (7.3%) out of four hundred patients showed severe LVH and one hundred and eighty-nine (47.3%) a normal geometry. In comparison to patients with normal geometry, patients with severe LVH were more likely to be male, older, and with more uncontrolled BP, especially regarding asleep values, multi-drug antihypertensive treatment and comorbidities. In comparison to patients with concentric or eccentric hypertrophy, patients with severe LVH had a significantly higher diastolic BP in the 24 h mean, awake and asleep values. A positive Sokolow-Lyon index did not predict LVH. However, patients with severe LVH were more likely to have T-wave-inversions V4–V6 in at least one lead. Conclusions: More than half of the patients with AHT have an abnormal geometry in our study (52.5%) and 7.3% a severe LVH. Patients with severe LVH have more often an uncontrolled AHT than patients with a normal LV geometry, despite more antihypertensive treatment. The Sokolow-Lyon index seems to be insufficient to detect LVH.
