- Aim Angina pectoris is common in patients with heart failure and reduced ejection fraction (HF-REF) but its relationship with outcomes has not been well defined. This relationship was investigated further in a retrospective analysis of the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA). Methods and results Four thousand, eight hundred and seventy-eight patients were divided into three categories: no history of angina and no chest pain at baseline (Group A; n = 1240), past history of angina but no chest pain at baseline (Group B; n = 1353) and both a history of angina and chest pain at baseline (Group C; n = 2285). Outcomes were examined using Kaplan-Meier and Cox regression survival analysis. Compared with Group A, Group C had a higher risk of non-fatal myocardial infarction or unstable angina (HR: 2.36, 1.54-3.61; P<0.001), this composite plus coronary revascularization (HR: 2.54, 1.76-3.68; P<0.001), as well as HF hospitalization (HR: 1.35, 1.13-1.63; P = 0.001), over a median follow-up period of 33 months. There was no difference in cardiovascular or all-cause mortality. Group B had a smaller increase in risk of coronary events but not of heart failure hospitalization. Conclusion Patients with HF-REF and ongoing angina are at an increased risk of acute coronary syndrome and HF hospitalization. Whether these patients would benefit from more aggressive medical therapy or percutaneous revascularization is not known and merits further investigation.

- Objectives: This study sought to examine the association between thyroid status and clinical outcomes in patients in the CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure) study. Background: Hypo- and hyperthyroidism were associated with worse clinical outcomes in the SCD-HeFT (Sudden Cardiac DeathinHeart Failure Trial). Methods: In CORONA, 4,987 patients underwent baseline thyroid-stimulating hormone (TSH) measurement, 237 of which(4.8%) were receiving thyroid replacement therapy (TRT). Patients were classified as euthyroid (TSH: 0.3 to 5.0μU/ml,and no TRT), hyperthyroid (<0.3 μU/ml and no TRT), or hypothyroid (>5.0 μU/ml and no TRT). The outcome composites of cardiovascular (CV) death or hospitalization for heart failure (HF), the components of this composite, and all-cause death were compared among hyperthyroid, hypothyroid, and euthyroid states, using multivariable models adjusting for previously reported prognostic variables. Results: A total of 91.3% of patients were euthyroid, 5.0% were hypothyroid, and 3.7% were hyperthyroid. Compared with euthyroid patients, hypothyroid patients were more likely to have a history of stroke, had worse renal function andhigher N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, were more likely to be treated with an antiarrhythmic drug (or have an implantable cardioverter defibrillator), and were less likely to smoke or be treated with a beta-blocker or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. In univariate analyses, hypothyroidism was associated with an increased risk of the composite outcome of CV death or HF hospitalization (hazard ratio: 1.29; 95% confidence interval: 1.07 to 1.57; p= 0.008), as well as all-cause death (HR: 1.36; 95% confidence interval: 1.03 to 1.76; p= 0.004). However, after adjustment for other known predictors of outcome, the associations were weakened, and when NT-proBNP was added to the models, the association between hypothyroidism and all outcomes was eliminated. Conclusions: Thyroid status is not an independent predictor of outcome in heart failure with reduced ejection fraction.

- Objectives: The purpose of this study was to examine the relationship between fatigue and clinical outcomes, using dyspnea as a comparator, in patients with left ventricular ejection fraction (LVEF)≤35% enrolled in the CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure) study. Background: Although fatigue is a common symptom in heart failure (HF), little is known about its association with prognosis. Methods: At baseline in CORONA, fatigue "during the past few days" was measured using a 5-point exertion scale (0= none, 1= heavy exertion, 2= moderate exertion, 3= slight exertion, 4= rest); a 4-point scale was used for dyspnea (1to4 as for fatigue). Patients were grouped into 3 categories: a fatigue score 0 to 1 (n= 535), fatigue score 2(n=1,632), and fatigue score 3 to 4 (n= 1,663); and a dyspnea score of 1 (n= 292), dyspnea score of 2(n=1,695), and dyspnea score of 3 to 4 (n= 1,843). The association between fatigue and dyspnea and the composite outcome of cardiovascular (CV) death or HF hospital stay and each component separately was examined using Kaplan-Meier analysis and Cox proportional-hazard models. We also examined all-cause mortality. Results: In univariate analyses, symptom severity was associated with a higher risk of CV death or HF hospital stay (fatigue: group 3, 49% [n= 810], vs. group 1, 30% [n= 160]; dyspnea: group 3, 50% [n= 918], vs. group 1, 28% [n= 82]) and all-cause mortality (fatigue: group 3, 38% [n= 623], vs. group 1, 24% [n= 130]; dyspnea: group 3, 38% [n=697], vs. group 1, 23% [n= 66], log-rank p< 0.0001 for all). After adjusting for other prognostic variables, including LVEF, New York Heart Association class, and N-terminal pro-B-type natriuretic peptide level, worse fatigue remained associated with higher risk of HF hospital stay but not mortality (worse dyspnea remained associated with a higher risk of both). An increase in fatigue (or dyspnea) between baseline and 6 months was also associated with worse outcomes. Conclusions: In HF, greater fatigue is associated with worse clinical outcomes. Closer attention should be paid to this symptom in clinical practice, with more done to standardize its measurement and understand its origins, with a view to improving treatment. © 2014 American College of Cardiology Foundation.
