Background : Incidence of stroke is higher than ischemic heart disease in Japanese. Left ventricular hypertrophy (LVH) is associated with an increased risk for stroke among hypertensives. We evaluated the risk of LVH among normotensives (SBP/DBP<120/80 mmHg) subjects. Methods: In a Japanese general population, 10755 subjects who were undertaken electrocardiogram and measured BP at baseline were evaluated Cornell product (CP) and Sokolow-Lyon (SL) voltage as markers of LVH (CP≥2440 mm ms and SL voltage>35 mm). Follow-up was performed for 10 years and incidence of stroke was evaluated. Results: Prevalence of CP-LVH were 2.7% for normotensives, 5.2 % for prehypertensives, 11.0 % for hypertensives, and that of SL-LVH were 8.6%, 11.4%, and 22.5%, respectively. In overall subjects, CP-LVH and SL-LVH were independent predictors of stroke [CP-LVH: hazard risk (HR) 1.65, 95% confidence interval (CI) 1.22–2.25, SL-LVH: HR 1.30, 95%CI 1.02–1.65] after adjustment for confounding factors. In Cox regression analysis in each stage of hypertension, hazard ratios of stroke in subjects with CP-LVH were higher among normotensives (HR 8.28, 95%CI 3.72–18.41) than among prehypertensives (HR 1.56, 95%CI 0.67–3.63) and hypertensives (HR 1.48, 95%CI 1.02–2.13) (Figure ), although that in subjects with SL-LVH were not significant (normotensives: HR 1.54, 95%CI 0.70–3.40, prehypertensives: HR 1.29, 95%CI 0.72–2.32, hypertensives: HR 1.21, 95%CI 0.90–1.62). Conclusion: The ECG-LVH independently predicted future stroke in a Japanese general population. The specificity of the Cornell product-LVH is higher than that of Sokolow-Lyon-LVH especially among normotensive subjects <120/80 mmHg.

Background : We have previously demonstrated that persistence or development of ECG left ventricular hypertrophy (LVH) by Cornell product criteria are associated with an increased risk of developing heart failure (HF) compared with regression or continued absence of LVH. We postulated that this relationship might be in part mediated via worse LV systolic function in patients with new and persistent LVH. Methods : Baseline and year-3 ECG LVH and LV midwall shortening (MWS) were examined in 725 patients in the LIFE echocardiographic substudy. MWS was measured and considered abnormal if <14.2%; stress-corrected MWS (scMWS) was considered abnormal if 2440 mm-msec. Results : Between baseline and 3 years follow-up, there was continued absence (n=260) or regression (n=167) of LVH in 427 patients and persistence (n=259) or development (n=39) of ECG LVH in 298 patients. Although there was no difference in baseline prevalence of abnormal MWS (23.4 vs 26.5%, p=0.389) or abnormal scMWS (24.6 vs 26.4%, p=0.663) between groups, after 3 years follow-up persistence or development of new LVH was associated with significantly lower mean MWS and scMWS and with higher prevalence and odds of abnormal MWS and scMWS than continued absence or regression of LVH (Table ). After controlling for differences in age, gender, race, treatment group, baseline and change from baseline to year-3 of heart rate, Sokolow-Lyon voltage, systolic and diastolic pressure and baseline severity of LVH by Cornell product, persistent or new ECG LVH remained associated with a >2-fold increased risk of abnormal MWS or scMWS at year 3. Conclusions : Persistence or development of new ECG LVH during antihypertensive therapy is associated with an increased risk of LV systolic dysfunction after 3 years of follow-up. These findings provide insight into a possible mechanism by which changes in ECG LVH are associated with changing risk of developing HF. < Midwall LV Function in Relation to Persistence or Development of ECG LVH Between Baseline and Year-3

Objective: Prehypertensive individuals are at increased risk for developing hypertension and their complication. Many studies show that 2/3 prehypertensive individuals develop hypertension after 4 years. ECG and echocardiography are the routine tests used to assess LV mass. The objective of the research to determine the percentage of change in left ventricular morphology in the ECG, echocardiography, which explore the characteristics of left ventricular structural changes by echocardiography in pre-hypertensive subjects. Materials and method: We studied a total of 50 prehypertensive, 30 males (60%) and 20 females (40%), mean age 48.20±8.47years. 50 normotensive volunteers as control participants. These subjects were examined for ECG and echocardiography. Results: In prehypertensive group, with 18% of left ventricular hypertrophy on electrocardiogram, 12% of left ventricular hypertrophy on echocardiography; in the control group, we did not find any subjects with left ventricular hypertrophy. In the group with left ventricular hypertrophy, mostly eccentric left ventricular hypertrophy (83.33%), concentric left ventricular hypertrophy is 16.67%. Restructuring of left ventricular concentric for 15.9% of subjects without left ventricular hypertrophy on echocardiography. Conclusion: There have been changed in left ventricular morphology even in prehypertensive

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 (&gt;115 g/m2 for men and &gt;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 &lt; 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.
