Tissue Doppler Imaging as a Prognostic Marker for Cardiovascular Events in Heart Failure with Preserved Ejection Fraction and Atrial Fibrillation

Prognostic Value of Tricuspid Annular Tissue Doppler Velocity in Heart Failure with Atrial Fibrillation

“…[14][15][16] In particular, the prevalence or severity of RV systolic and diastolic dysfunction was also reported to be increased even in patients with HFPEF. 13 The presence of AF seems to result in early alteration of LV systolic and diastolic function, which in turn causes impaired contractility and diastolic LV stiffness.…”

“…Compared with patients in our previously published study (>90% in NYHA classes I and II; EF in the events group, 58.1%), which demonstrated the usefulness for the combination of septal s 0 and e 0 , patients in the present study had somewhat advanced NYHA classes (>90% in NYHA classes II and III), and the event group showed lower EFs (49.6%). 16 However, the impact of AF on the outcomes of patients with HF has been controversial. 31,32 Interestingly, the prognostic implication of AF may be different depending on LV EF: the Candesartan in Heart Failure-Assessment of Reduction in Mortality and Morbidity study showed a more pronounced effect of AF in patients with preserved EF (>40%) compared with the reduced-EF group, 31 but Rusinaru et al 32 failed to find a relationship of AF and prognosis in those with EFs > 50%.…”

“…These findings are similar to previous observations from our laboratory related to the independent prognostic power of septal s 0 and e 0 in patients, particularly those with AF. 16 Therefore, AF is believed to be a progressive process that develops along with functional or structural changes in both the left atrium and the left ventricle. Furthermore, the loss of atrial kicking contributes to LV filling, which is responsible for atrial dysfunction and dilation.…”

Depressed Atrial Function in Diastolic Dysfunction: A Speckle Tracking Imaging Study

“…) receiving less attention. Those studies that have investigated LA function have utilized 2‐dimensional (2D) echocardiography and tissue Doppler imaging (TDI) . TDI has also been used to demonstrate reduced LA function in patients with diastolic dysfunction with exercise; this latter technique is limited by a dependence on the angle of insonance.…”

Prognostic Value of Pulsed Tissue Doppler Imaging for the Assessment of Left Ventricular Systolic Function in Patients with Nonischemic Dilated Cardiomyopathy

“…14,15 Although several studies have focused on its utility as an early marker of LV contractile impairment, [16][17][18][19] few data are available concerning its prognostic value. 20 It should be noted that other indexes obtained by color TD, such as those exploring systolic dyssynchrony, were shown to be powerful markers of cardiovascular risk in HF patients. 7,8 However, it should be argued that one of these studies enrolled patients with a severely compromised LV systolic function (mean LV EF 24.7%), 7 whilst the other had a relatively short follow-up (7 months).…”
