ObjectivesTo investigate: (1) the prevalence of left ventricular hypertrophy (LVH) in elderly primary care patients with long-standing asymptomatic hypertension, and (2) the diagnostic value of ECG as a screening tool in the detection of LVH compared with echocardiography in this specific patient population.Design and settingsA cross-sectional study in five general practices in the south-east of the Netherlands.ParticipantsPatients with primary care-managed hypertension, aged between 60 and 85 years, without known heart failure.Primary and secondary outcome measuresBetween June 2010 and January 2013, the patients underwent structured interviews, blood pressure assessment, laboratory testing, ECGs and echocardiograms. The primary outcome was to investigate the ability of ECG to detect LVH, compared with echocardiography as a reference test (gold standard).ResultsFour hundred and twenty-two patients (44% male; ages 70±7 years) who underwent ECG and echocardiographic assessment to determine LVH were included. The median duration of hypertension was 10 (4–15) years. The overall prevalence of LVH was 44%, which increased with age (p<0.001); up to 60% of patients were ≥75 years. ECG intimated LVH in 47 patients (11%) but in only 26 of those (55%) was LVH confirmed by echocardiography. The sensitivity of ECG for detecting LVH was poor (14%).ConclusionsAsymptomatic primary care patients with long-standing hypertension have a high prevalence of previously undetected LVH, which increases with age. ECG is inadequate for detecting LVH in these patients. Early detection of LVH could potentially create more awareness for the optimal regulation of hypertension and compliance to therapy. Therefore, echocardiography should be considered a screening device for the detection of LVH in this population.

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 &gt;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&gt;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&lt;0.001). CL identified a larger percentage of LVH in DM compared to non-DM individuals (8.0% vs. 5.6%, p&lt;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&gt;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

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.
