A reduction of HRV has been reported in several cardiovascular and noncardiovascular diseases. Depressed HRV after MI may reflect a decrease in vagal activity directed to the heart. HRV in patients surviving an acute MI reveal a reduction in total and in the individual power of spectral components. The presence of an alteration in neural control is also reflected in a blunting of day-night variations of RR interval. In post-MI patients with a very depressed HRV, most of the residu… WebIn both unadjusted and multivariable adjusted analyses, patients with paroxysmal atrial fibrillation were less frequently prescribed oral anticoagulant therapy than those with persistent atrial fibrillation (50.3% vs 64.2%; adjusted risk ratio [RR] 0.74; 95% confidence interval [CI], 0.72-0.76).
