Prescribing patterns of evidence-based heart failure pharmacotherapy and outcomes in the ASIAN-HF registry: a cohort study.
Angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs), β blockers, and mineralocorticoid receptor antagonists (MRAs) are of proven benefit and are recommended by guidelines for management of patients with heart failure and reduced ejection fraction (HFrEF). We aimed to examine the first prospective multinational data from Asia on prescribing patterns of guideline-directed medical therapies and analyse its effect on outcomes.
In the prospective multinational ASIAN-HF registry (with enrolment from 46 centres in 11 countries in Asia), we enrolled patients aged 18 years or older, with symptomatic heart failure (stage C, with at least one episode of decompensated heart failure in the past 6 months that resulted in admission to hospital or was treated in an outpatient clinic) and left ventricular systolic dysfunction (ejection fraction ≤40% on baseline echocardiography, consistent with 2016 European Society of Cardiology guidelines). We excluded patients with heart failure caused by severe valvular heart disease, life-threatening comorbidity with a life expectancy of less than 1 year, who were unable or unwilling to give consent, or who had concurrent participation in a clinical trial. Patients were followed up for 3 years for the outcomes of death and cause-specific admittance to hospital. Primary outcomes were uptake of guideline-directed medical therapies (as proportions) by therapeutic class, achieved doses as proportions of guideline-recommended doses, and their association with 1-year composite outcome of all-cause death or admittance to hospital because of heart failure. This study is registered with ClinicalTrials.gov, number NCT01633398.
Between Oct 1, 2012, and Dec 31, 2015, we enrolled 5276 patients with HFrEF (mean age 59·6 years [SD 13·2], 77% men, body-mass index 24·9 kg/m2 [5·1], 33% New York Heart Association class III or IV). Follow-up data were available for 4544 (90%) of 5061 eligible patients taking medication for heart failure, with median follow-up of 417 days (IQR 214-735). ACE inhibitors or ARBs were prescribed to 3868 (77%) of 5005 patients, β blockers to 3975 (79%) of 5061, and MRAs to 2998 (58%) of 5205, with substantial regional variation. Guideline-recommended dose was achieved in only 17% of cases for ACE inhibitors or ARB, 13% for β blockers, and 29% for MRAs. Country (all three drug classes), increasing body-mass index (ACE inhibitors or ARBs and MRAs), and in-patient recruitment (ACE inhibitors or ARBs and β blockers) were associated with attainment of guideline-recommended dose (all p<0·05). When adjusted for indication bias, increasing drug doses, from low dose (1-<25% of guideline-recommended dose) upwards were associated with lower hazards of a 1-year composite outcome for ACE inhibitors or ARBs and β blockers compared with non-users. The lowest adjusted hazards were in the group that attained guideline-recommended doses above 50% (hazard ratio [HR] 0·54, 95% CI 0·50-0·58 for ACE inhibitors or ARBs [50-99·9%]; HR 0·47, 0·46-0·50 for β blockers, and HR 0·77, 0·72-0·81 for MRAs [≥100%]).
Guideline-directed medical therapies at recommended doses are underutilised in patients with HFrEF. Improved uptake and uptitration of guideline-directed medical therapies are needed for better patient outcomes.

Adherence to the ESC Heart Failure Treatment Guidelines in Spain: ESC Heart Failure Long-term Registry.
To estimate the percentage of heart failure patients in Spain that received the European Society of Cardiology recommended treatments, and in those that did not, to determine the reasons why.
The study included 2834 consecutive ambulatory patients with heart failure from 27 Spanish hospitals. We recorded general information, the treatment indicated, and the reasons why it was not prescribed in some cases. In patients who met the criteria to receive a certain drug, true undertreatment was defined as the percentage of patients who, without justification, did not receive the drug.
In total, 92.6% of ambulatory patients with low ejection fraction received angiotensin converting enzyme inhibitors or angiotensin receptor blockers, 93.3% beta-blockers, and 74.5% mineralocorticoid receptor antagonists. The true undertreatment rates were 3.4%, 1.8%, and 19.0%, respectively. Target doses were reached in 16.2% of patients receiving angiotensin converting enzyme inhibitors, 23.3% of those with angiotensin receptor blockers, 13.2% of those prescribed beta-blockers, and 23.5% of those with mineralocorticoid receptor antagonists. Among patients who could benefit from ivabradine, 29.1% received this drug. In total, 36% of patients met the criteria for defibrillator implantation and 90% of them had received the device or were scheduled for implantation, whereas 19.6% fulfilled the criteria for resynchronization therapy and 88.0% already had or would soon have the device. In patients who met the criteria, but did not undergo device implantation, the reasons were not cost-related.
When justified reasons for not administering heart failure drugs were taken into account, adherence to the guideline recommendations was excellent. Exclusive use of the percentage of treated patients is a poor indicator of the quality of healthcare in heart failure. Measures should be taken to improve the attainment of optimal dosing in each patient.

Optimization of heart FailUre medical Treatment after hospital discharge according to left ventricUlaR Ejection fraction: the FUTURE survey.
No clinical practice guidelines are available for the treatment of heart failure (HF) in patients with preserved left ventricular ejection fraction (LVEF).
To determine how cardiologists manage medical treatment in HF patients after hospital discharge, according to LVEF.
The FUTURE study was a cross-sectional survey conducted in HF outpatients by French private cardiologists between September 2007 and August 2008. Patients had to have been hospitalized within the previous 18 months with a diagnosis of HF. Clinical data and HF treatments (angiotensin-converting enzyme inhibitors [ACEIs], angiotensin receptor blockers [ARBs], beta-blockers, diuretics and aldosterone antagonists) were recorded retrospectively, with precise information on drug doses, at two successive time points (at hospital discharge and at the index consultation). HF treatment was compared in patients with reduced (less than or equal to 40%) versus preserved (more than 40%) LVEF.
Completed data were available for 1137 HF patients enrolled by 424 cardiologists. Mean patient age was 72±11 years; LVEF was reduced in 56% and preserved in 44%. The therapeutic approach was similar in the two groups, both at hospital discharge and at the index consultation. At the index consultation, HF treatment was: beta-blocker (74%); ACEI/ARB (83%); loop diuretic (86%); aldosterone antagonist (31%). The majority of patients (62%) received a beta-blocker plus an ACEI or an ARB; 56% reached more than or equal to 50% of the target dose for each treatment. There were no major differences in treatments and dosages between the groups with low and preserved LVEF. In 15% of cases where the drug dose was not increased, fear of adverse events was reported as the reason.
The FUTURE survey showed a similar approach to HF treatment irrespective of LVEF. Compared with previous studies, we saw an improvement in the use of recommended HF drugs, especially beta-blockers. However, achievement of target doses could be improved.

Appropriateness of Prescriptions of Recommended Treatments in Organisation for Economic Co-operation and Development Health Systems: Findings Based on the Long-Term Registry of the European Society of Cardiology on Heart Failure.
This observational study aimed to identify clinical variables and health system characteristics associated with incomplete guideline application in drug treatment of patients with chronic heart failure (HF) across 15 countries.
Three data sets were used: European Society of Cardiology Heart Failure Registry, Organisation for Economic Co-operation and Development's Health System Characteristics Survey, and Organisation for Economic Co-operation and Development Health Statistics 2013. Patient and country variables were examined by multilevel, multiple logistic regression. The study population consisted of ambulatory patients with chronic HF and reduced ejection fraction. Inappropriateness of prescription of pharmacological treatments was defined as patients not prescribed at least one of the two recommended treatments (angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers and beta-blockers) or treated with both medications but at suboptimal dosage and in absence of documented contraindication/intolerance.
Of 4605 patients, 1097 (23.8%) received inappropriate drug prescriptions with a large variation within and across countries, with 18.5% of the total variability accounted for by between-country health structure characteristics. Patient-level characteristics such as having mitral regurgitation (odds ratio 1.4; 95% confidence interval 1.1-1.7) was significantly associated with inappropriate prescription of recommended drugs, whereas chronic obstructive pulmonary disease (odds ratio 0.7; 95% confidence interval 0.5-0.9) was associated with more appropriate prescriptions. Among the country-level variables, incentives or obligation to comply with guidelines increased the probability of prescription appropriateness.
Combining clinical variables with health system characteristics is a promising exercise to explain the appropriateness of recommended drug prescriptions. Such an understanding can help decision makers to design more effective policies to improve adherence to guidelines, improve health care outcomes, and potentially reduce costs.
