[The prediction of atrial fibrillation in patients with arterial hypertension]

Abstract

Aim: To study the parameters of the structural and functional state of the myocardium in patients with hypertension, to determine their prognostic value on the risk of atrial fibrillation (AF).

Patients and methods: The study involved 72 people: patients with hypertension and AF, with isolated hypertension and apparently healthy individuals. All of them performed echocardiography, blood pressure monitoring and monitoring of cardiogram.

Results: The dilatation of left atrial was founded: patients with the atrial fibrillation on the background of hypertension observed the most pronounced changes in the left atrial. In patients with hypertension without arrhythmias and in combination with atrial fibrillation severe left ventricular hypertrophy was observed. Left ventricle systolic function in groups has been stored but in patients with atrial fibrillation on the background of hypertension was significantly lower. The risk of atrial fibrillation in patients with hypertension prognostic value are the only values of the age, the volume index of the left atrial to the body surface area and left ventricular ejection fraction.

Conclusions: The risk of AF in hypertension occurs over the age of 55 and each subsequent year increases it in 1,2 times, it increases with an index value of the left atrial to the body surface over 29 ml/m2 and with a decrease in left ventricular ejection fraction less than 58%.
