ABSTRACT OBJECTIVE: To determine the diagnostic accuracy of Electrocardiography (ECG) of Left Ventricular Hypertrophy, taking echocardiography as a gold standard. SUBJECTS & METHODS: It was a Cross-Sectional Study. The study was conducted in the Medicine Department, Services Hospital, Lahore from February 19, 2018, to August 19, 2018. A total of 300 cases were enrolled. Standardized a 12-lead ECG was used in subjects by Cardiofax electrocardiograph paper speed at 25mm/sec. Two dimensionally (2D) guided M Mode echocardiographic measurements were taken and the presence/absence of LVH was recorded. The collected data was entered and analyzed in computer software SPSS software v25.0. A 2x2 table was drawn to calculate the Sn, Sp, PPV, NPV and diagnostic accuracy of ECG for LVH taking Echocardiographic findings as a gold standard. RESULTS: Out of 300 cases, 172(57.33%) were male and 128(42.67%) as females. The mean age was 38.72±5.64 years. Accuracy of electrocardiography (ECG) for LVH diagnosis taking echocardiography as the gold standard was calculated as 85.21%, 84.18%, 82.88%, 86.36% and 84.67% as Sn, Sp, PPV, NPV, and diagnostic accuracy respectively. CONCLUSION: Diagnostic accuracy of Electrocardiography (ECG) for LVH diagnosis is higher and this diagnostic modality can be used in areas where echocardiography is not available. KEYWORDS: Electrocardiography (ECG), Diagnostic Accuracy, Echocardiography, Left Ventricular Hypertrophy.

AbstractLeft ventricular hypertrophy (LVH) is considered a cardiac condition with life-threatening complications. Detected LVH is a strong predictor of cardiovascular diseases and death. This condition is normally diagnosed at offices. We aimed to determine the prevalence and associated factors of electrocardiographic-LVH (ECG-LVH) among adults in a Thai rural community. A cross-sectional study was conducted in Na-Yao rural community of Thailand in 2020. A total of 638 individuals aged ≥ 20 years were interviewed using standardized structured questionnaires related to demographic information, risk behaviors, comorbidities and anthropometric measurements. LVH was determined by Sokolov-Lyon and Cornell criteria based on the collected electrocardiograms. The prevalence of ECG-LVH among adults was 6.6%. The factors independently associated with ECG-LVH were being male (AORs 2.04, 95% CI 1.05–3.98), history of diabetes mellitus (AORs 1.01, 95% CI 1.01–1.02), and hypertensive crisis ≥ 180/110 mmHg (AORs 7.24, 95% CI 1.31–39.92). However, resting heart rate was negatively associated with ECG-LVH (p < 0.05). Our data emphasized that LVH was one of the significant health problems among adults in a rural community. This condition could lead to severe complications. Thus, effective detection and public health interventions should be provided at the community level.

Hypertension Guidelines

Aim. To evaluate doctors’ knowledge, attitude, and practices and predictors of adherence to Malaysian hypertension guidelines (CPG 2008). Methods. Twenty-six doctors involved in hypertension management at Penang General Hospital were enrolled in a cross-sectional study. Doctors’ knowledge and attitudes towards guidelines were evaluated through a self-administered questionnaire. Their practices were evaluated by noting their prescriptions written to 520 established hypertensive outpatients (20 prescriptions/doctor). SPSS 17 was used for data analysis. Results. Nineteen doctors (73.07%) had adequate knowledge of guidelines. Specialists and consultants had significantly better knowledge about guidelines’ recommendations. Doctors were positive towards guidelines with mean attitude score of 23.15±1.34 points on a 30-point scale. The median number of guidelines compliant prescriptions was 13 (range 5–20). Statistically significant correlation (rs = 0.635, P<0.001) was observed between doctors’ knowledge and practice scores. A total of 349 (67.1%) prescriptions written were guidelines compliant. In multivariate analysis hypertension clinic (OR = 0.398, P=0.008), left ventricular hypertrophy (OR = 0.091, P=0.001) and heart failure (OR = 1.923, P=0.039) were significantly associated with guidelines adherence. Conclusion. Doctors’ knowledge of guidelines is reflected in their practice. The gap between guidelines recommendations and practice was seen in the pharmacotherapy of uncomplicated hypertension and hypertension with left ventricular hypertrophy, renal disease, and diabetes mellitus.

Background Obesity is a chronic metabolic disorder associated with cardiovascular disease (CVD) increasing morbidity-mortality rates. It is apparent that a variety of adaptations/alterations in cardiac structure and function occurs as excessive adipose tissue accumulates. This leads to a decrease in diastolic compliance, eventually resulting in an increase in left ventricular filling pressure and left ventricular enlargement.Objective To evaluate left ventricular hypertrophy (LVH) among  obese using electrocardiographic (ECG) criteria.Methods A cross-sectional study was conducted on 74 children aged 10-15 years from February 2009 to October 2009. The subjects were divided into obese and control groups. Physical examination and standard 12 lead electrocardiography (ECG) were done in both groups.Results Of 37 obese children, LVH were featured in 3 subjects, while in control group, only 1 child had LVH (P= 0.304). We found that mean RV6 in obese and control group were 9.8446 (SD 3.5854) and 11.9662 (SD 3.2857), respectively (P=0.005). As an additional findings, we found that birth weight was related to obesity in children.Conclusion There is no relation between obesity and left ventricular using ECG criteria in obese children aged 10-15 years.

We compared the diagnostic accuracy of electrocardiographic (ECG) criteria for left ventricular hypertrophy (LVH) in 119 randomly selected from 400 patients with thalassemia major treated at the Department of Child Health, Medical School, University of Indonesia, Jakarta. Echocardiographically derived left ventricular hypertrophy (EchoLVH), both for body surface area (BSA)-indexed and height-indexed, served as the gold standard. There were 57 girls and 62 boys available, ranging in age from 5 to 27 years. ECG criteria for LVH was detected in 23 outof119 patients, while echo-LVH was detected in 47 patients if BSA-indexed LVH was used, or 22 patients if height-indexed LVH was used. The sensitivity and specificity of ECG-LVH were 25.5 and 84.7% respectively if BSA indexed LVH was used as gold standard, or 36.4% and 84.5%, respectively, when height indexed echo-LVH was used. It is concluded that ECG criteria for LVH has a low sensitivity and hjgh specificity in detecting increased left ventricular mass in children with thalassemia major.

Background: Prehypertension is a major public health concern. The condition is much prevalent in India and is often associated with other cardiovascular (CV) risk factors and independently increases the risk of hypertension and subsequent cardiovascular events. Several studies have shown microalbuminuria as a sensitive marker for predicting CV risk in pre-hypertensive. The objective of this study was to assess the prevalence of microalbuminuria in prehypertension and to determine its association with electrocardiogram (ECG) and echocardiographic (Echo) parameters indicative of CV risk.Methods: This cross-sectional study included a total of 75 subjects aged between 22 and 50 years, with prehypertension attending the medicine department of a tertiary care teaching hospital in Chennai, Tamil Nadu from April 2012 to November 2012. All the study subjects were evaluated with ECG and echo for cardiac changes. Statistical analysis was performed using SPSS software trial version-16 to determine the association of microalbuminuria with cardiac changes.Results: The prevalence of microalbuminuria among the included subjects was 60%. Mean value of urinary excretion of microalbuminuria was 90±2.1 µg/dl with a male preponderance in this study. Pre-hypertensive subjects with microalbuminuria had significant changes of left ventricular hypertrophy (LVH) as evident in ECG than those without microalbuminuria. Microalbuminuric prehypertensive subjects also had significant echocardiographic changes like LVH and diastolic dysfunction than those without microalbuminuria.Conclusions: The cardiovascular changes like left ventricular hypertrophy and diastolic dysfunction were evident in younger age among pre-hypertensives with microalbuminuria than those without microalbuminuria.

Diagnostic Capability

Introduction: Based on a small sample of patients with hypertension, a few studies have reported that the newly proposed SD + SV4 criterion for left ventricular hypertrophy (LVH) is better than traditional criteria. This study aimed to verify the diagnostic capability of the SD + SV4 criterion in a Chinese population with or without hypertension and to analyze the factors affecting the diagnostic accuracy of LVH. Methods: A total of 248 patients with LVH or paroxysmal supraventricular tachycardia (PSVT) discharged from Fuwai Hospital from January 2010 to July 2018 were enrolled. Patients with LVH were diagnosed according to the left ventricular mass index calculated by the echocardiogram parameter as the gold standard in this study. The receiver operating curve (ROC) curve was performed to assess the diagnostic capability and cut-off values of the SD + SV4, RavL + SV3, and SV1 + RV5/RV6 criteria for LVH. Then, multivariate logistic regression analyses were performed to in­vestigate the factors affecting the accuracy of the SD + SV4 criterion. Results: There were 170 (68.5%) patients with hypertension and 110 (44.4%) with PSVT. According to echocardiography, 107 (43.1%) patients were diagnosed with LVH. The area under the curve (AUC) of the SD + SV4 criterion was the largest compared with that of the RavL + SV3 and SV1 + RV5/RV6 criteria (AUC 0.765 vs. 0.718 vs. 0.713, respectively). The sex-specific SD + SV4 criterion had the highest consistency with the gold standard (r = 0.532 ± 0.054, p < 0.01), accompanied by the highest sensitivity (70.1%) and specificity (85.8%). The cut-off values of the sex-specific SD + SV4 criterion for LVH were ≥2.65 mV (male)/2.15 mV (female). The left ventricular ejection fraction (LVEF; OR 0.920, 95% CI 0.882–0.959, p < 0.001) was significantly different between the SD + SV4 criterion and the gold standard for LVH after adjusting for hypertension, PSVT history, body surface area, interventricular septum thickness, posterior wall thickness, and left ventricular internal diameter. Conclusion: The newly proposed SD + SV4 criterion provides improved sensitivity and accuracy for the diagnosis of LVH in the Chinese population. A decrease in LVEF is an independent factor affecting the diagnostic accuracy of LVH.
