Abstract
OBJECTIVES The purpose of this study was to characterize the clinical profile, treatment patterns, and clinical outcomes of patients with comorbid diabetes mellitus (DM) and heart failure with reduced ejection fraction (HFrEF) in a contemporary, real-world U.S. outpatient registry in the context of evolving treatment strategies. BACKGROUND Specific antihyperglycemic classes have differential risks and benefits with respect to HF. Limited data are available evaluating contemporary treatment patterns and outcomes of patients with comorbid DM and HFrEF. METHODS Among 4,970 patients with chronic HFrEF (≤40%) across 152 U.S. sites in the CHAMP-HF prospective, observational registry (2015 to 2017), we examined therapies and clinical outcomes by DM status. RESULTS Median age was 68 (58 to 75) years of age; 29% were women; 73.5% were white; and 64% had coronary artery disease. Overall, 42% (n = 2,085) had comorbid DM with a median hemoglobin A1c (HbA1c) level of 7.2% (interquartile range [IQR]: 6.4% to 8.3%). One-fourth of DM patients (24%) were not treated with an antihyperglycemic therapy. Most patients with DM were taking 1 (46%) or 2 (23%) antihyperglycemic therapies: metformin (40%); insulin (33%); sulfonylureas (24%); dipeptidyl peptidase-4 inhibitors (10%); glucagon-like peptide (GLP)-1 receptor agonists (4%); sodium-glucose cotransporter (SGLT)-2 inhibitors (2%); and thiazolidinediones (2%). Among patients with DM, 62%, 16%, 80%, and 33.5% were receiving any angiotensin-converting enzyme (ACE) inhibitor/angiotensin receptor blockers (ARBs), angiotensin receptor-neprilysin inhibitor (ARNI), β-blockers, or mineralocorticoid receptor antagonists (MRAs) at baseline, respectively. Among patients without DM, corresponding baseline rates were 65%, 15%, 80%, and 37%, respectively. Patients with or without DM were infrequently treated with guideline-directed HFrEF therapies at target doses (≤27% across classes). During median 15-month follow-up, patients with DM experienced higher rates of all-cause mortality or HF hospitalization (30% vs. 23%, respectively), independent of 11 pre-specified covariates (adjusted hazard ratio: 1.35 (95% confidence interval: 1.21 to 1.52); p < 0.001). CONCLUSIONS Despite higher risk-adjusted clinical event rates in patients with comorbid HFrEF and DM, guideline-directed medical therapies for both disease states are incomplete and represent an important target for quality improvement through multidisciplinary care pathways.

Abstract
β-Blockers are a standard therapy for acute myocardial infarction (AMI) due to their better short-term and long-term outcomes. However, β-blockers are often under-prescribed in chronic obstructive pulmonary disease (COPD) patients with AMI, since they are thought be related to bronchospasm. The aim of this study was to investigate the association between the usage of β-blockers and the risk of mortality in COPD patients after first AMI via a nationwide, population-based cohort study. In this retrospective study, we identified 186,326 patients with AMI diagnosed between January 2000 and December 2012, 23,116 of whom had COPD, from the National Health Insurance Research Database. A total of 7609 patients (32.92%) were prescribed β-blockers, while 15,507 were not. The β-blocker patients were stratified into selective and non-selective β-blocker groups. Multivariate Cox proportional hazards models were used to estimate adjusted hazard ratios (HR) with 95% confidence intervals (95% CI). Selective β-blocker use showed a reduced risk of mortality, as compared with patients without β-blockers (HR 0.93; 95% CI 0.89-0.98; p < 0.01) while non-selective β-blocker groups did not increase the risk of mortality compared to the patients without β-blockers (HR 0.98; 95% CI 0.94-1.02; p = 0.38). In addition, the use of β-blockers was found to be associated with a reduced risk of mortality in most stratified analyses which was seen particularly in males, patients aged 65 years and above, and in individuals with an array of comorbidities. These findings suggest that β-blockers improve overall survival among COPD patients after first AMI.

Abstract
BACKGROUND The cardiovascular disease pandemic has promoted the cardiovascular polypill as one of the most scalable public health strategies to improve cardiovascular risk by increasing accessibility and adherence to treatments. Data from randomized clinical trials has shown that the polypill strategy significantly improves adherence as well as risk factor control (cholesterol and blood pressure), however, to date, no information from phase IV registries has been available. METHODS We conducted a multicentre, observational and prospective registry of a polypill-based treatment strategy. A total of 1193 patients in Mexico were included. Patient demographics, clinical history, blood pressure, analysis of blood lipids and the Framingham risk score were measured at baseline and after 12 months of treatment with the CNIC-Ferrer polypill. RESULTS At one year with the polypill, systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels changed from mean 146.9 mmHg to 128 mmHg (p <0.001), and from 89.1 mmHg to 80.4 mmHg (p <0.001) respectively. LDLc levels were significantly reduced 132.5-107.6 mg/dL (p <0.001). The 10 year Framingham cardiovascular disease risk was also reduced in the high-risk group (33.7 + 22.0 vs. 21.2 + 14.8; p <0.001) and in the intermediate risk group (23.7 + 14.8 vs. 12.7 + 11.4; p <0.001). CONCLUSIONS To our knowledge, the results of the current study constitute the first real life data on the impact of a polypill therapy on cardiovascular risk factor control. The results show major improvements on the primary outcome, above and beyond those presented previously in the setting of randomized clinical trials.

PloS one. 2019;(3):e0213187
Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) less often receive β-blockers after acute myocardial infarction (AMI). This may influence their outcomes after AMI. This study evaluated the efficacy of β-blockers after AMI in patients with COPD, compared with non-dihydropyridine calcium channel blockers (NDCCBs) and absence of these two kinds of treatment. METHODS AND RESULTS We conducted a nationwide population-based cohort study using data retrieved from Taiwan National Health Insurance Research Database. We collected 28,097 patients with COPD who were hospitalized for AMI between January 2004 and December 2013. After hospital discharge, 24,056 patients returned to outpatient clinics within 14 days (the exposure window). Those who received both β-blockers and NDCCBs (n = 302) were excluded, leaving 23,754 patients for analysis. Patients were classified into the β-blocker group (n = 10,638, 44.8%), the NDCCB group, (n = 1,747, 7.4%) and the control group (n = 11,369, 47.9%) based on their outpatient prescription within the exposure window. The β-blockers group of patients had lower overall mortality risks (adjusted hazard ratio [95% confidence interval]: 0.91 [0.83-0.99] versus the NDCCB group; 0.88 [0.84-0.93] versus the control group), but the risk of major adverse cardiac events within 1 year was not statistically different. β-blockers decreased risks of re-hospitalization for COPD and other respiratory diseases by 12-32%. CONCLUSIONS The use of β-blockers after AMI was associated with a reduced mortality risk in patients with COPD. β-blockers did not increase the risk of COPD exacerbations.

Abstract
BACKGROUND There is a paucity of information about the gender differences in clinical outcomes of successful percutaneous coronary intervention (PCI) compared with medical therapy (MT) in patients with coronary chronic total occlusions (CTOs). OBJECTIVES We aimed to investigate the impact of gender on long-term clinical outcomes associated with successful CTO-PCI versus MT in patients with CTOs. METHODS Between January 2007 and December 2016, a total of 1702 patients with ≥1 CTO were enrolled. After exclusion, 1294 patients with 1520 CTOs were analyzed and were divided into the female group (n = 304, 23.5%) and the male group (n = 990, 76.5%). The patients in the female or male group were assigned to a MT group or successful CTO-PCI group according to the treatment strategy. In the female group, they were divided into two groups: 177 patients in the MT group and 127 patients in the successful CTO-PCI group. In the male group, they were divided into two groups: 623 patients in the MT group and 367 patients in the successful CTO-PCI group. The primary outcome was cardiac death. The secondary outcome was major adverse cardiac event (MACE). RESULTS The median overall follow-up duration was 3.6 (IQR, 2.1-5.0) years, there were no significant differences between the MT and successful CTO-PCI groups with respect to the prevalence of cardiac death (MT vs. successful PCI: 6.8% vs. 3.9%, p=0.287) and MACE (20.9% vs. 21.3%, p=0.810) in female patients. In the male group, the occurrence of cardiac death (MT vs. successful PCI: 6.6% vs. 3.8%, p=0.066) was similar between the two groups. The MACE rate (30.0% vs. 18.5%, p < 0.001) was significantly higher in the MT group. Heart failure (hazard ratio 3.40, 95% confidence interval 1.23-9.40, p=0.018) was an independent predictor of cardiac death in female patients. CONCLUSIONS Successful CTO-PCI was not associated with reduced risk of cardiac death compared with medical therapy alone in both female and male patients. However, men have a significant reduction in MACE rate after successful CTO-PCI. Aggressive CTO-PCI should be considered carefully among female patients.

Abstract
BACKGROUND The interaction between chronic medications on admission and the association between serum potassium level and outcome in patients with acute heart failure (AHF) are unknown. METHODS Observational intercontinental study of patients admitted with AHF. 15954 patients were included from 12 cohorts in 4 continents. Main outcome was 90-day mortality. Clinical presentation (medication use, hemodynamics, comorbidities), demographic, echocardiographic, and biochemical data on admission were recorded prospectively in each cohort, with prospective adjudication of outcomes. RESULTS Positive and negative linear relationships between 90-day mortality and sK+ above 4.5 mmol/L (hyperkalemia) and below 3.5 mmol/L (hypo-kalemia) were observed. Hazard ratio for death was 1.46 [1.34-1.58] for hyperkalemia and 1.22 [1.06-1.40] for hypokalemia. In a fully adjusted model, only hyperkalemia remained associated with mortality (HR 1.03 [1.02-1.04] for each 0.1 mmol/l change of sK+ above 4.5 mmol/L). Interaction tests revealed that the association between hyperkalemia and outcome was significantly affected by chronic medications. The association between hyperkalemia and mortality was absent for patients treated with beta blockers and in those with preserved renal function. CONCLUSIONS In patients with AHF, sK+ > 4.5 mmol/L appears to be associated with 90-day mortality. B-blockers have potentially a protective effect in the setting of hyperkalemia.

Abstract
BACKGROUND Hyperkalaemia is a common co-morbidity in patients with heart failure with reduced ejection fraction (HFrEF). Whether it affects the use of renin-angiotensin-aldosterone system inhibitors and thereby negatively impacts outcome is unknown. Therefore, we investigated the association between potassium and uptitration of angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB) and its association with outcome. METHODS AND RESULTS Out of 2516 patients from the BIOSTAT-CHF study, potassium levels were available in 1666 patients with HFrEF. These patients were sub-optimally treated with ACEi/ARB or beta-blockers and were anticipated and encouraged to be uptitrated. Potassium levels were available at inclusion and at 9 months. Outcome was a composite of all-cause mortality and heart failure hospitalization at 2 years. Patients' mean age was 67 ± 12 years and 77% were male. At baseline, median serum potassium was 4.3 (interquartile range 3.9-4.6) mEq/L. After 9 months, 401 (24.1%) patients were successfully uptitrated with ACEi/ARB. During this period, mean serum potassium increased by 0.16 ± 0.66 mEq/L (P < 0.001). Baseline potassium was an independent predictor of lower ACEi/ARB dosage achieved [odds ratio 0.70; 95% confidence interval (CI) 0.51-0.98]. An increase in potassium was not associated with adverse outcomes (hazard ratio 1.15; 95% CI 0.86-1.53). No interaction on outcome was found between baseline potassium, potassium increase during uptitration, or potassium at 9 months and increased dosage of ACEi/ARB (Pinteraction > 0.5 for all). CONCLUSION Higher potassium levels are an independent predictor of enduring lower dosages of ACEi/ARB. Higher potassium levels do not attenuate the beneficial effects of ACEi/ARB uptitration.

Abstract
AIMS: The occurrence of drug intolerance (DI) after an acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) is an important reason for quitting treatment. Nevertheless, the association between DI and major cardiac and cerebrovascular events (MACCE) is poorly reported in the literature, therefore, we analysed potential relationship between DI and MACCE (a composite of ACS, PCI, heart failure, and stroke) during follow-up. METHODS AND RESULTS From 1 January 2014 to 31 December 2015, 891 consecutive patients after ACS or coronary revascularization were referred to cardiac rehabilitation (CR) programme and included in a dedicated registry where DI was analysed and treatment appropriately tailored. Three hundred and nine patients (34.7%) developed DI, 26.9% of them were female. Angiotensin-converting enzyme (ACE) inhibitors and statins were the most frequent drugs which caused DI, followed by beta-blockers and calcium channel blockers, in 13.1%, 12.8%, 7.5%, and 5.5% of patients, respectively. During a median follow-up of 18 (interquartile range 11-24) months after CR, MACCE occurred in 14.1% of patients with DI and 8.1% without DI (P = 0.007). At multivariable model, DI to 1 drug [odds ratio (OR) 1.8, 95% confidence interval (CI) 1.01-3.18; P = 0.043] or to 2 drugs (OR 2.56, 95% CI 1.27-5.17; P = 0.008) were independently associated to MACCE. Regarding the association of specific class of prognostic drugs to MACCE, only DI to ACE-inhibitors was independently associated with MACCE (OR 2.31, 95% CI 1.14-4.65; P = 0.019). CONCLUSION DI was frequently encountered in real-world clinical practice and was significantly associated with MACCE during follow-up. This study suggests that early occurrence of DI could be considered to be an adjunctive cardiovascular risk factor during secondary prevention.

BMC pharmacology & toxicology. 2016;:9
Abstract
BACKGROUND Although the pathophysiological mechanisms of arterial hypertension are different in obese and lean patients, hypertension guidelines do not include specific recommendations for obesity-related hypertension and, therefore, there is a considerable uncertainty on which antihypertensive drugs should be used in this condition. Moreover, studies performed in general population suggested that some antihypertensive drugs may increase body weight, glycemia and LDL-cholesterol but it is unclear how this impact on drug choice in clinical practice in the treatment of obese hypertensive patients. Therefore, in order to identify current preferences of practitioners for obesity-related hypertension, in the present work we evaluated antihypertensive drug therapy in a cohort of 129 pharmacologically treated obese hypertensive patients (46 males and 83 females, aged 51.95 ± 10.1 years) that came to our observation for a nutritional consultation. METHODS Study design was retrospective observational. Differences in the prevalence of use of the different antihypertensive drug classes among groups were evaluated with χ(2) square analysis. Threshold for statistical significance was set at p < 0.05. RESULTS 41.1 % of the study sample was treated with one, 36.4 % with two and the remaining 22.5 % with three or more antihypertensive drugs. In patients under single drug therapy, β-blockers, ACEIs and ARBs accounted each for about 25 % of prescriptions. The prevalence of use of β-blockers was about sixfold higher in females than males. Diuretics were virtually never used in monotherapy regimens but were used in more than 60 % of patients on dual antihypertensive therapy and in all patients assuming three or more drugs. There was no significant difference in the prevalence of use of any of the aforementioned drugs among patients with obesity of type I, II and III or between patients with or without metabolic syndrome. CONCLUSIONS Our data show that no first choice protocol seems to be adopted in clinical practice for the treatment of obesity-related hypertension. Importantly, physicians do not seem to differentiate drug use according to the severity of obesity or to the presence of metabolic syndrome or to avoid drugs known to detrimentally affect body weight and metabolic profile in general population.

Abstract
AIMS: To assess physicians' adherence to guideline-recommended medications for the treatment of chronic heart failure (CHF) with reduced ejection fraction. METHODS AND RESULTS QUALIFY is an international prospective observational longitudinal survey of 7092 CHF outpatients recruited 1-15 months after hospitalization for heart failure from September 2013 to December 2014 in 547 centres in 36 countries. We constructed a five-class guideline adherence score for angiotensin converting enzyme inhibitors (ACEIs), beta-blockers, angiotensin receptor blockers (ARBs), mineralocorticoid receptor antagonists, and ivabradine. The adherence score was good in 67%, moderate in 25%, and poor in 8% of patients. Adherence was lower in women than men but there were differences in age (65.7 ± 12.5 years women vs. 62.2 ± 12.4 years men, P < 0.001) and the proportion of women at ≥50% target dose of beta-blockers was lower in those >67 years (median) (11% vs. 16.2%, P = 0.005). Geographic variations were observed with lower adherence scores in Central/Eastern European countries. The proportion of patients at target dose and ≥50% of target dose was low (27.9% and 63.3% for ACEIs, 14.8% and 51.8% for beta-blockers, 6.9% and 39.5% for ARBs, and 6.9% and 39.5% for ivabradine, respectively). It was also lower in patients most recently hospitalized (<6 vs. ≥6 months) except for beta-blockers. CONCLUSION This international survey shows that adherence to guideline-recommended medications is relatively satisfactory but the dosage of recommended CHF medications is usually suboptimal. Action plans aimed at improving adherence to guidelines are required.
