Digoxin and 30-day all-cause hospital admission in older patients with chronic diastolic heart failure
2014, American Journal of MedicineCitation Excerpt :A post hoc analysis of DIG data suggested that the risk of unstable angina hospitalization was higher among those with higher ejection fraction, so that compared with ejection fraction <35%, those with 35%-55% and >55% had 17% and 57% independent higher risk, respectively.8 It has been suggested that viable hypertrophied myocardium with abnormal coronary microcirculation might make patients with diastolic heart failure more prone to unstable angina.9-11 However, it is not clear why this risk could be higher among older patients receiving digoxin, and importantly, whether this risk would be attenuated in those receiving beta-blockers.

2010, International Journal of CardiologyCitation Excerpt :This is consistent with the findings from the Coronary Artery Surgery Study and the Veteran Affairs Cooperative Study that suggested that coronary revascularization was associated with improved survival in patients with IHD and LVEF > 35% [18,19]. HF patients with normal or near normal LVEF are more likely to have viable ischemic myocardium, which has been shown to determine both the degree of improvement in LV function and the long-term outcomes after revascularization [20–25]. The association between a higher mean LVEF and the presence of viable ischemic myocardium may also explain the higher prevalence of unstable angina pectoris in patients receiving coronary revascularization in our study.
