Abstract Objective Comparison of cardiac function in patients with renal parenchymal hypertension and essential hypertension. Methods Selection of patients with renal parenchymal hypertension 66 cases (renal hypertension group) and 66 cases of patients with primary hypertension (hypertension group), the measurement of plasma brain natriuretic peptide in patients with precursor(NT- proBNP), left ventricular ejection fraction(LVEF), left ventricular end diastolic diameter (LVIDd), left ventricular the systolic diameter (LVIDs), calculate the left ventricular mass index (LVMI). The differences of NT- proBNP levels and left ventricular structure parameters were analyzed and compared between the groups. Results Renal hypertension group, left ventricular mass index (LVMI)、left ventricular end diastolic diameter (LVIDd)、left ventricular systolic diameter(LVIDs) and plasma NT- proBNP [(126.7±29.6)g/m2、(49.9±3.8)mm、(32.2±4.1)mm、2 150ng/L] were higher than those in primary hypertension group [(96.1 ±10.0)g/m2、(41.6 ±4.7)mm、(28.0 ±2.0)mm、162.5ng/L], left ventricular ejection fraction (LVEF)[(64.3±6.5)%] was lower than that of primary hypertension group [(67.6±6.1)%]. The difference was statistical y significant (P<0.05). Conclusion The effect of renal parenchymal hypertension on left ventricular hypertrophy and cardiac insufficiency was more significant than that in primary hypertension group .
