Abstract Background The presence of atrial fibrillation (AF) has been demonstrated to be associated with poor clinical outcomes in heart failure patients with reduced ejection fraction. Objective This study aimed to elucidate the impact of the presence of atrial fibrillation (AF) on the clinical characteristics, therapeutics, and outcomes in patients with heart failure and preserved ejection fraction (HFpEF). Methods PURSUIT-HFpEF is a multicenter prospective observational study including patients hospitalized for acute heart failure with left ventricular ejection fraction of >50%. Patients with acute coronary syndrome or severe valvular disease were excluded. Results Of 486 HFpEF patients (age, 80.8±9.0 years old; male, 47%) from 24 cardiovascular centers, 199 (41%) had AF on admission. Patients with AF had lower systolic blood pressures (142±27 vs. 155±35mmHg, p<0.0001) and higher heart rates (91±29 vs. 82±26bpm, p<0.0001) than those without. There was no difference in the usage of inotropes or mechanical ventilation between the 2 groups. A higher quality of life score (EQ5D, 0.72±0.27 vs. 0.63±0.30, p=0.002) was observed at discharge in patients with than without AF. In addition, AF patients tended to demonstrate lower in-hospital mortality rates (0.5% vs. 2.4%, p=0.09) and shorter hospital stays (20.3±12.1 vs. 22.6±18.4 days, p=0.09) than those without. During a mean follow up of 360±111 days, mortality (14.1% vs. 15.3) and heart failure re-hospitalization rates (13.1% vs. 13.9%) were comparable between the 2 groups. Conclusion In contrast to heart failure patients with reduced ejection fraction, AF on admission was not associated with poor long-term clinical outcomes among HFpEF patients. Several in-hospital outcomes were better in patients with AF than in those without. Acknowledgement/Funding None

Patients With Heart Failure

There are multiple proposed mechanisms for the pathophysiology of heart failure (HF) with preserved ejection fraction (HFpEF). We hypothesized that coronary microvascular dysfunction is common in these patients. In a prospective, observational study, patients undergoing cardiac catheterization with HFpEF [left ventricular (LV) ejection fraction ≥ 50% and with clinical HF] were compared with similar patients without HFpEF. Patients with ≥50% stenosis were excluded, and coronary flow reserve (CFR) and the index of microvascular resistance (IMR) were measured after adenosine administration using a guidewire, with CFR ≤ 2 and IMR ≥ 23 being abnormal. Baseline characteristics and CFR and IMR were compared in 30 HFpEF patients and 14 control subjects. Compared with control subjects, HFpEF patients were older (65.4 ± 9.6 vs. 55.1 ± 3.1 yr, P < 0.01), had higher numbers of comorbidities (4.4 ± 1.5 vs. 2.6 ± 1.9, P = 0.002), had higher median B-type natriuretic peptide [161 (interquartile range: 75–511) pg/dl vs. 37 (interquartile range: 18.5–111) pg/dl, P < 0.01], and had higher LV end-diastolic pressure (17.8 ± 4.2 vs. 8.4 ± 4.2, P < 0.01). HFpEF patients had lower CFR (2.55 ± 1.60 vs. 3.84 ± 1.89, P = 0.024) and higher IMR (26.7 ± 10.3 vs. 19.7 ± 9.7 units, P = 0.037) than control subjects. Most (71.4%) control subjects had normal coronary physiology, whereas 36.7% of HFpEF patients had both abnormal CFR and IMR and another 36.7% had either abnormal CFR or IMR. In conclusion, this is the first study that has reported invasively determined CFR and IMR in HFpEF patients. We demonstrated the presence of four distinct coronary physiology groups in HFpEF patients. Investigation into the potential mechanisms for these findings is needed. NEW & NOTEWORTHY In this prospective observational study of patients with heart failure with preserved ejection fraction (HFpEF), we found that patients with HFpEF had more abnormalities of coronary flow and resistance than asymptomatic control patients, indicating that coronary microvascular dysfunction may play a role in the HFpEF disease process.
