| [Objectives]To investigate correlation between basic heart rate and left ventricular hypertrophyin primary hypertension patients with dipper blood pressure and dipper heart rate.[Methods]Primary hypertension patients were admitted in First Quanzhou Hospital affiliatedto Fujian Medical University from January 2014 to January 2015.Based on dynamicblood pressure and ECG, patients with dipper blood pressure and heart rate wereselected. A total of 244 patients were selected, including 116 males and 128 females,38-78(59.58±10.35) years old. Patients were divided into left ventricular hypertrophygroup(n=115) and non-left ventricular hypertrophy group(n=129) based on ColorDoppler Echocardiography findings. All selected patients were registered for clinicaldata and basic heart rates. Correlation between clinical data, basic heart rates and leftventricular hypertrophy were compared and analyzed. Multiple factor logistic regressionanalysis was performed for parameters related to left ventricular hypertrophy(p<0.05),to clarify influencing factors of left ventricular hypertrophy.[Results]1. Analysis of clinical data in two groups: LVMI and basic heart rate in leftventricular hypertrophy group were higher(p<0.05). Sex and smoking history werenegatively correlated with LVMI(p<0.05). Basic heart rate was positively correlatedwith LVMI(p<0.05).2. Analysis of dynamic blood pressure and ECG findings in two groups: Day andnight mean heart rates in left ventricular hypertrophy group were higher than those innon-left ventricular hypertrophy group(p<0.05). Decreased percentage of night heartrate in left ventricular hypertrophy group was lower than those in non-left ventricularhypertrophy group(p<0.05). Day and night mean heart rates were positively correlatedwith LVMI(p<0.05). Decreased percentage of night heart rate was negatively correlatedwith LVMI(p<0.05).3. Logistic regression analysis: Basic heart rate was the independent risk factor forleft ventricular hypertrophy(95%CI: 1.010-1.178, p<0.05).[Conclusions]Basic heart rate was positively correlated with left ventricular hypertrophy inprimary hypertension patients with dipper blood pressure and dipper heart rate. Highbasic heart rate is the independent risk factor for left ventricular hypertrophy. |
