- OBJECTIVES The authors investigated the relationship between past or incident myocardial infarction (MI) and car-diovascular (CV) events in heart failure with preserved ejection fraction (HFpEF). BACKGROUND MI and HFpEF share some common risk factors. The prognostic significance of MI in patients with HFpEF is uncertain. METHODS The authors pooled data from 3 trials-CHARM Preserved (Candesartan Cilexietil in Heart Failure Assessment of Reduction in Mortality and Morbidity), I-Preserve (Irbesartan in Heart Failure With Preserved Systolic Function), and the Americas region of TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) (N 1/4 8,916)-and examined whether MI before or following enrollment independently predicted CV death and heart failure (HF) hospitalization. RESULTS At baseline, 2,668 patients (30%) had history of MI. Prior MI was independently associated with greater risk of CV death (4.7 vs. 3.5 events/100 patient-years [py], adjusted hazard ratio [HR]: 1.42 [95% confidence interval (CI): 1.23 to 1.64]; p < 0.001). Excess sudden death drove this difference (1.9 vs. 1.2 events/100 py, adjusted HR: 1.55 [95% CI: 1.23 to 1.97]; p < 0.001). There was no difference in HF hospitalization (5.9 vs. 5.5 events/100 py, adjusted HR: 1.05, 95% CI: 0.92 to 1.19) or HF death by prior MI. During follow-up, MI occurred in 336 patients (3.8%). Risk of CV death increased 31-fold in the first 30 days after first post-enrollment MI, and remained 58% higher beyond 1 year after MI. Risk of first or recurrent HF hospitalization increased 2.4-fold after MI. CONCLUSIONS Prior MI in HFpEF is associated with greater CV and sudden death but similar risk of HF outcomes. Patients with HFpEF who experience MI are at high risk of subsequent CV death and HF hospitalization. These data highlight the importance of primary and secondary prevention of MI in patients with HFpEF.

- BACKGROUND Although heart failure with preserved ejection fraction (HFpEF) is considered a disease of the elderly, younger patients are not spared from this syndrome. OBJECTIVES This study therefore investigated the associations among age, clinical characteristics, and outcomes in patients with HFpEF. METHODS Using data on patients with left ventricular ejection fraction >= 45% from 3 large HFpEF trials (TOPCAT [Aldosterone Antagonist Therapy for Adults With Heart Failure and Preserved Systolic Function], I-PRESERVE [Irbesartan in Heart Failure With Preserved Systolic Function], and CHARM Preserved [Candesartan Cilexetil in Heart Failure Assessment of Reduction in Mortality and Morbidity]), patients were categorized according to age: <= 55 years (n = 522), 56 to 64 years (n = 1,679), 65 to 74 years (n = 3,405), 75 to 84 years (n = 2,464), and >= 85 years (n = 398). This study compared clinical and echocardiographic characteristics, as well as mortality and hospitalization rates, mode of death, and quality of life across age categories. RESULTS Younger patients (age <= 55 years) with HFpEF were more often obese, nonwhite men, whereas older patients with HFpEF were more often white women with a higher prevalence of atrial fibrillation, hypertension, and chronic kidney disease (eGFR <60 ml/min/1.73 m(2)). Despite fewer comorbidities, younger patients had worse quality of life compared with older patients (age >= 85 years). Compared with patients age <= 55 years, patients age >= 85 years had higher mortality (hazard ratio: 6.9; 95% confidence interval: 4.2 to 11.4). However, among patients who died, sudden death was, proportionally, the most common mode of death (p < 0.001) in patients age <= 55 years. In contrast, older patients (age >= 85 years) died more often from noncardiovascular causes (34% vs. 20% in patients age <= 55 years; p < 0.001). CONCLUSIONS Compared with the elderly, younger patients with HFpEF were less likely to be white, were more frequently obese men, and died more often of cardiovascular causes, particularly sudden death. In contrast, elderly patients with HFpEF had more comorbidities and died more often from noncardiovascular causes.

Journal article (peer-reviewed)abstract
- BACKGROUND: -International geographic differences in outcomes may exist for clinical trials of heart failure and reduced ejection fraction (HF-REF), but there are few data for those with preserved ejection fraction (HF-PEF). METHODS AND RESULTS: -We analyzed outcomes by international geographic region in the Irbesartan in Heart Failure with Preserved systolic function trial (I-Preserve), the Candesartan in Heart failure Assessment of Reduction in Mortality and morbidity (CHARM)-Preserved trial, the CHARM-Alternative and CHARM-Added HF-REF trials, and the Controlled Rosuvastatin Multinational Trial in HF-REF (CORONA). Crude rates of heart failure hospitalization varied by geographic region, and more so for HF-PEF than for HF-REF. Rates in patients with HF-PEF were highest in the United States/Canada (HF hospitalization rate 7.6 per 100 patient-years in I-Preserve; 8.8 in CHARM-Preserved), intermediate in Western Europe (4.8/100 and 4.7/100), and lowest in Eastern Europe/Russia (3.3/100 and 2.8/100). The difference between the United States/Canada versus Eastern Europe/Russia persisted after adjustment for key prognostic variables: adjusted hazard ratios 1.34 (95% confidence interval, 1.01-1.74; P=0.04) in I-Preserve and 1.85 (95% confidence interval, 1.17-2.91; P=0.01) in CHARM-Preserved. In HF-REF, rates of HF hospitalization were slightly lower in Western Europe compared with other regions. For both HF-REF and HF-PEF, there were few regional differences in rates of all-cause or cardiovascular mortality. CONCLUSIONS: -The differences in event rates observed suggest there is international geographic variation in 1 or more of the definition and diagnosis of HF-PEF, the risk profile of patients enrolled, and the threshold for hospitalization, which has implications for the conduct of future global trials.

- Background Sudden death (SD) and pump failure death (PFD) are leading modes of death in heart failure and preserved ejection fraction (HFpEF). Risk stratification for mode-specific death may aid in patient enrichment for new device trials in HFpEF. Methods Models were derived in 4116 patients in the Irbesartan in Heart Failure with Preserved Ejection Fraction trial (I-Preserve), using competing risks regression analysis. A series of models were built in a stepwise manner, and were validated in the Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM)-Preserved and Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trials. Results The clinical model for SD included older age, men, lower LVEF, higher heart rate, history of diabetes or myocardial infarction, and HF hospitalization within previous 6 months, all of which were associated with a higher SD risk. The clinical model predicting PFD included older age, men, lower LVEF or diastolic blood pressure, higher heart rate, and history of diabetes or atrial fibrillation, all for a higher PFD risk, and dyslipidaemia for a lower risk of PFD. In each model, the observed and predicted incidences were similar in each risk subgroup, suggesting good calibration. Model discrimination was good for SD and excellent for PFD with Harrell's C of 0.71 (95% CI 0.68-0.75) and 0.78 (95% CI 0.75-0.82), respectively. Both models were robust in external validation. Adding ECG and biochemical parameters, model performance improved little in the derivation cohort but decreased in validation. Including NT-proBNP substantially increased discrimination of the SD model, and simplified the PFD model with marginal increase in discrimination. Conclusions The clinical models can predict risks for SD and PFD separately with good discrimination and calibration in HFpEF and are robust in external validation. Adding NT-proBNP further improved model performance. These models may help to identify high-risk individuals for device intervention in future trials.

Journal article (peer-reviewed)abstract
- Background: The incidence of pneumonia and subsequent outcomes has not been compared in patients with heart failure and reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). Objectives: This study aimed to examine the rate and impact of pneumonia in the PARADIGM-HF (Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With Angiotensin Converting Enzyme Inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure) and PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in Heart Failure with Preserved Ejection Fraction) trials. Methods: The authors analyzed the incidence of investigator-reported pneumonia and the rates of HF hospitalization, cardiovascular death, and all-cause death before and after the occurrence of pneumonia, and estimated risk after the first occurrence of pneumonia in unadjusted and adjusted analyses (the latter including N-terminal pro–B-type natriuretic peptide). Results: In PARADIGM-HF, 528 patients (6.3%) developed pneumonia after randomization, giving an incidence rate of 29 (95% CI: 27 to 32) per 1,000 patient-years. In PARAGON-HF, 510 patients (10.6%) developed pneumonia, giving an incidence rate of 39 (95% CI: 36 to 42) per 1,000 patient-years. The subsequent risk of all trial outcomes was elevated after the occurrence of pneumonia. In PARADIGM-HF, the adjusted hazard ratio (HR) for the risk of death from any cause was 4.34 (95% CI: 3.73 to 5.05). The corresponding adjusted HR in PARAGON-HF was 3.76 (95% CI: 3.09 to 4.58). Conclusions: The incidence of pneumonia was high in patients with HF, especially HFpEF, at around 3 times the expected rate. A first episode of pneumonia was associated with 4-fold higher mortality.

Journal article (peer-reviewed)abstract
- OBJECTIVES This study examined the relationship between prior pacemaker implantation and clinical outcomes in patients with heart failure with preserved ejection fraction (HFpEF). BACKGROUND Conventional right ventricular pacing causes electrical and mechanical left ventricular dyssynchrony and may worsen left ventricular systolic dysfunction and HF. Whether conventional pacing is also associated with worse outcomes in HFpEF is unknown. METHODS Patient data were pooled from the CHARM-Preserved (Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity), I-PRESERVE (Irbesartan in Heart Failure with Preserved Ejection Fraction), and TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist trial) studies and were examined for the association between having a pacemaker and the risk of the primary composite of cardiovascular death or HF hospitalization, the individual components of the composite, the 2 main modes of cardiovascular death (i.e., sudden death and pump failure death), and all-cause death in unadjusted and adjusted analyses. RESULTS Of the 8,466 patients included, 682 patients (8%) had a pacemaker. Pacemaker patients were older and more often men and had lower body mass indexes, estimated glomerular filtration rates, and blood pressures but higher concentrations of N-terminal pro-B-type natriuretic peptide than those without a pacemaker. The rate of the primary composite outcome in pacemaker patients was almost twice that in patients without a pacemaker (13.6 vs. 7.6 per 100 patient-years of follow up, respectively), with a similar finding for HF hospitalizations (10.8 vs. 5.1 per 100 patient-years, respectively). This risk rate persisted after adjusting for other prognostic variables (hazard ratio [HR] for the composite outcome: 1.17; 95% confidence interval [CI]: 1.02 to 1.33; p = 0.026), driven mainly by HF hospitalization (HR: 1.37; 95% CI: 1.17 to 1.60; p < 0.001). The risk of death was not significantly higher in pacemaker patients in the adjusted analyses. CONCLUSIONS These findings raise the possibility that right ventricular pacing-induced left ventricular dyssynchrony may be detrimental in HFpEF patients.

Journal article (peer-reviewed)abstract
- Aims Stroke is an important problem in patients with heart failure (HF), but the intersection between the two conditions is poorly studied across the range of ejection fraction. The prevalence of history of stroke and related outcomes were investigated in patients with HF. Methods and results Individual patient meta-analysis of seven clinical trials enrolling patients with HF with reduced (HFrEF) and preserved ejection fraction (HFpEF). Of the 20 159 patients with HFrEF, 1683 (8.3%) had a history of stroke, and of the 13 252 patients with HFpEF, 1287 (9.7%) had a history of stroke. Regardless of ejection fraction, patients with a history of stroke had more vascular comorbidity and worse HF. Among those with HFrEF, the incidence of the composite of cardiovascular death, HF hospitalization, stroke, or myocardial infarction was 18.23 (16.81-19.77) per 100 person-years in those with prior stroke vs. 13.12 (12.77-13.48) in those without [hazard ratio 1.37 (1.26-1.49), P < 0.001]. The corresponding rates in patients with HFpEF were 14.16 (12.96-15.48) and 9.37 (9.06-9.70) [hazard ratio 1.49 (1.36-1.64), P < 0.001]. Each component of the composite was more frequent in patients with stroke history, and the risk of future stroke was doubled in patients with prior stroke. Among patients with prior stroke, 30% with concomitant atrial fibrillation were not anticoagulated, and 29% with arterial disease were not taking statins; 17% with HFrEF and 38% with HFpEF had uncontrolled systolic blood pressure (& GE;140 mmHg). Conclusion Heart failure patients with a history of stroke are at high risk of subsequent cardiovascular events, and targeting underutilization of guideline-recommended treatments might be a way to improve outcomes in this high-risk population.

- Aims The incidence and predictors of stroke in patients with heart failure and preserved ejection fraction (HF-PEF), but without atrial fibrillation (AF), are unknown. We described the incidence of stroke in HF-PEF patients with and without AF and predictors of stroke in those without AF. Methods and results We pooled data from the CHARM-Preserved and I-Preserve trials. Using Cox regression, we derived a model for stroke in patients without AF in this cohort and compared its performance with a published model in heart failure patients with reduced ejection fraction (HF-REF)-predictive variables: age, body mass index, New York Heart Association class, history of stroke, and insulin-treated diabetes. The two stroke models were compared and Kaplan-Meier curves for stroke estimated. The risk model was validated in a third HF-PEF trial. Of the 6701 patients, 4676 did not have AF. Stroke occurred in 124 (6.1%) with AF and in 171 (3.7%) without AF (rates 1.80 and 1.00 per 100 patient-years, respectively). There was no difference in performance of the stroke model derived in the HF-PEF cohort and the published HF-REF model (c-index 0.71, 95% confidence interval 0.57-0.84 vs. 0.73, 0.59-0.85, respectively) as the predictive variables overlapped. The model performed well in the validation cohort (0.86, 0.62-0.99). The rate of stroke in patients in the upper third of risk approximated to that in patients with AF (1.60 and 1.80 per 100 patient-years, respectively). Conclusions A small number of clinical variables identify a subset of patients with HF-PEF, but without AF, at elevated risk of stroke.

Journal article (peer-reviewed)abstract
- AimsTo investigate the relationship between angina pectoris and fatal and non-fatal clinical outcomes in heart failure with reduced and preserved ejection fraction (HF-REF and HF-PEF, respectively). Methods and resultsOf 7599 patients in the CHARM program, 5408 had ischaemic heart disease; 3855 had HF-REF (ejection fraction 45%) and 1553 had HF-PEF. These patients were separated into three groups: no history of angina, previous angina, and current angina. Three coronary outcomes were examined: fatal or non-fatal myocardial infarction (MI); MI or hospitalization for unstable angina (UA); and MI, UA or coronary revascularization. The composite heart failure outcome of cardiovascular death or heart failure hospitalization (HFH) was also analysed, along with its components and all-cause mortality. New York Heart Association functional class was worse in both HF-REF and HF-PEF patients with current angina compared with patients without angina (P<0.001 and P=0.005 respectively), despite similar clinical examination findings and ejection fraction. Patients with current angina had a higher risk of all three coronary outcomes (adjusted hazard ratios ranging from 1.8-3.1) than those without angina but did not have a higher risk of heart failure outcomes or all-cause mortality. ConclusionIn patients with heart failure current angina is associated with significantly more functional limitation and a higher risk of coronary events, across the spectrum of left ventricular ejection fraction.

Severity of renal impairment in patients with heart failure and atrial fibrillation: implications for non-vitamin K antagonist oral anticoagulant dose adjustment
- 2016
-
In: European Journal of Heart Failure. - : Wiley. - 1388-9842. ; 18:9, s. 1162-1171
-
Journal article (peer-reviewed)abstract
- Aims: The non-vitamin K antagonist oral anticoagulants (NOACs) have varying degrees of renal elimination which may be challenging in patients with heart failure (HF) and atrial fibrillation (AF). We examined the severity and variation in renal impairment, and the proportion of patients requiring NOAC cessation or dose reduction. Methods and results: A retrospective analysis of patients with HF and AF in the Candesartan in Heart failure Assessment of Reduction in Mortality and Morbidity programme was carried out. Trends in renal impairment over 26 months were defined using Cockcroft–Gault (CG), simplified Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. Mean estimated glomerular filtration rate (eGFR) was worse at every time point in patients with AF compared with those without AF, the difference being ∼11 mL/min (CG), 9 mL/min (CKD-EPI), and 7 mL/min (MDRD). As renal function declined, CG classified a greater proportion of patients as having moderate or severe CKD and agreement with MDRD/CKD-EPI declined. At least moderate renal impairment was present in a quarter of patients with AF at baseline, a third by study completion, and approaching a half at least once during follow-up. The projected need for NOAC dose reduction was accordingly high, though it varied between individual NOACs due to different criteria for adjustment. Conclusions: Renal impairment in patients with HF and AF is common, fluctuates, progresses, and frequently mandates NOAC dose reduction, though the need for cessation is rare. Baseline renal function, the method of estimating GFR, and intensity of monitoring should be considered when commencing oral anticoagulation. © 2016 The Authors.
