Background: Left ventricular hypertrophy (LVH) is traditionally classified as concentric or eccentric based on LV relative wall thickness. We evaluated the prediction of ischemic stroke in a new 4-group LVH classification based on LV concentricity (mass/end-diastolic volume 0.67 ) and indexed LV end-diastolic volume (EDV) in the general Chinese population. Methods: The cross-sectional study consisted of 11,037 general Chinese population (mean age 54 years; 54% women) from Northeast China Rural Cardiovascular Health (NCRCH) study who underwent echocardiography measurement. A 4-tiered classification of LVH was proposed where eccentric LVH is subdivided into “indeterminate hypertrophy (n=484)” and “dilated hypertrophy (n=386)” and concentric LVH into “thick hypertrophy (n=246)” and “both thick and dilated hypertrophy (n=138)” based on the presence of increased LV end-diastolic volume. Results: Compared with normal LV geometry (2.6%), indeterminate (7.4%) and thick hypertrophy (10.2%) showed a higher prevalence of ischemic stroke (p<0.05). Ischemic stroke was significantly greater in participants with indeterminate (adjusted odd ratio [OR]:1.635, 95% confidence interval [CI]: 1.115–2.398) and thick (2.143 [1.329–3.456]) hypertrophy but not significantly in those with dilated (1.251 [0.803–1.950]) and both thick and dilated hypertrophy (0.926 [0.435–1.971]) compared with normal geometry in multivariable analysis. Additionally, the continuous parameters of LV concentricity 0.67 (OR, 1.067; 95% CI, 1.024–1.113 per 1 SD increment) was independently associated with the presence of ischemic stroke in multivariable analysis adjusted for age, sex, race, physical activity, current smoking and drinking status, BMI, TC, hypertension and diabetes, while LVEDV/BSA was not (OR, 0.957; 95% CI, 0.859–1.065 per 1 SD increment). Conclusions: In a large-scale Asian population, we identified that thick hypertrophy carried the greatest odd for ischemic stroke, independently of traditional risk factors, followed by indeterminate hypertrophy. The new 4-tiered categorization of LVH can permit a better understanding of which subjects are at high enough risk for ischemic stroke to warrant early targeted therapy.

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 &gt;115 g/m2 in males and &gt;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&lt;0.0001 for both comparisons) and RE5 (p=0.042). PLP also had better specificity than the RE4 criteria (p&lt;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&lt;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.

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.
