Abstract
Background: Atrial fibrillation (AF) is the most prevalent chronic arrhythmia in the heart. AF accounts for one-third of rhythm disorder hospitalizations. AF increases profoundly the risk of stroke, heart failure, and death. This study used P-wave and transthoracic echocardiography with tissue Doppler imaging (TDI) to determine paroxysmal AF predictors in hypertensive individuals. Methods: This case control study was performed on 100 hypertensive adult patients. They were classified into two equal group: Group I included hypertensive patients diagnosed to have paroxysmal AF. Group II (control group) included hypertensive patients with normal sinus rhythm. All subjects were subjected to electrocardiographic and conventional and tissue Doppler Imaging measurements. Results: Pmax had significantly increased in PAF patients compared to sinus rhythm patients. PAL, PAR, PAI, LR, LI and IR had significantly increased in PAF patients compared to sinus rhythm patients. In Multivariate logistic regression analysis, Pmax, PAL, PAI, PAR, LR, LI and IR were found to be independent predictors for PAF. Therefore, Pmax, PAL PAI, PAR, LR, LI and IR were found to be significant predictors for PAF. Best cut-off values for Pmax, PAL, PAI, PAR, LR, LI and IR were: (118, 81, 61, 49.9, 34, 20 and 16 ms) with sensitivity (76, 96, 96, 88, 82, 86 and 77.5 ), specificity (84, 100, 98, 92, 78, 82 and 76) and the AUC of (0.850, 0.979, 0.987, 0.961, 0.836, 0.891 and 0.798) respectively. Conclusions: Electrocardiographic P-wave analysis and echocardiographic TDI may identify hypertension patients at risk for paroxysmal AF, since the combination of Pmax and TDI may help in predicting the development of AF in hypertensive individuals.
