Objective: This study was to determine whether different risk factors were associated with different type of left ventricular (LV) geometric abnormalities. Methods: This retrospective analysis included 2290 hypertensive participants without other cardiovascular disease, valve disease and with ejection fraction ≥50%. The type of LV geometric abnormality was defined on the basis of the new classification system. Results: LV geometric abnormalities were detected in 1479 subjects (64.6%), wherein concentric LV remodeling is the most common LV geometric abnormality (40.3%). Large waist circumference (WC) and neck circumference (NC) were positively associated with concentric LV remodeling, whereas body mass index (BMI) [odds ratio (OR) 0.89, 95% CI 0.85∼0.92, P ＜ 0.001] and systolic blood pressure (SBP) (OR 0.99, 95% CI 0.98∼0.99, P = 0.018) were inversely associated with concentric abnormalities. SBP and age were positively associated with eccentric dilated LVH, while male was inversely associated with eccentric dilated left ventricular hypertrophy (LVH). Age was the strongest risk factor for eccentric dilated LVH (OR 1.05, 95% CI 1.03∼1.07, P ＜ 0.001). Age, NC, SBP, hyperuricemia, and alcohol use were positively associated with concentric LVH, whereas BMI (OR 0.95, 95% CI 0.90∼0.99, P = 0.033) and male (OR 0.12, 95% CI 0.07∼0.18, P ＜ 0.001) were negatively associated with concentric LVH. Conclusion: The prevalence of hypertensive LV geometric abnormality in rural area of Southern China was obvious higher. Compared with eccentric LV geometric abnormalities, there were more risk factors, including large WC and NC, age, NC, SBP, hyperuricemia, alcohol use, BMI and gender, which were associated with concentric LV geometric abnormalities.
