Study Of Characteristics Of Cardiac Structure And Function In Hypertensive Patients With Atrial Fibrillation

Objective: To study the characteristics of cardiac structure and function and its clinical significance in hypertension with atrial fibrillation.Methods: According to JNC7 the diagnostic criteria of hypertension and ACC/AHA/ESC 2006 the guideline of diagnostic criteria of AF,the objects were divided into 4 groups: essential hypertension with atrial fibrillation group including 49 patients,atrial fibrillation without essential hypertension group including 49 patients,essential hypertension group including 33 patients and the control group including 49 healthy subjects. Cardiac structure and function were assessed by means of echocardiography.Results: IVSTd,LVM,LAV was significant difference among the normal control, the AF and the essential hypertension with AF groups (P<0.05).LVPWTd in the essential hypertension with atrial fibrillation group was significantly greater than those in the other groups (P<0.05).LVEF in the essential hypertension with atrial fibrillation group was significantly lower than those in the other groups(P<0.05).RAV in the atrial fibrillation and the essential hypertension with atrial fibrillation groups were greater than those in the the control and the essential hypertension groups. In the atrial fibrillation group, LAV intensity correlated with LVM,LVMI.Conclusion: Atrium, left ventricular function and structure changed in the atrial fibrillation patients with or without hypertension. More severe change was found in hypertensive patients with atrial fibrillation. Atrium volume and LVM might be new predictors for the atrial fibrillation and screening high risk population of atrial fibrillation.
