Shared Decision-Making and Cardiovascular Complications of Androgen Deprivation Therapy: an Educational Initiative for Oncology Team Members in Colorado, USA.

Patients with prostate cancer may experience side effects of androgen deprivation therapy (ADT) such as cardiovascular (CV) complications. Oncology team members should actively communicate with patients about these complications. On the other hand, shared decision-making (SDM) has been shown to improve patient-physician communication. We developed brochures focused on CV complications of ADT and SDM. We proceeded to deliver these brochures to participating oncology offices and then carried out a survey of team members in these offices. We obtained responses from 31 oncology team members. Our survey revealed that about half of the participants (48%) rarely applied SDM in their oncology practice, and only about one-third (32%) sometimes applied SDM. After reading our brochures, the majority of respondents could correctly answer questions about SDM and CV complications of ADT. Improvement in scores after reading our materials was significant for both CV complications of ADT and SDM (e.g., CV complications of ADT: z = 6.153, p-value < 0.001, and SDM z = 6.456, p-value < 0.001). Implementation of SDM and an improved awareness of the CV complications of ADT can lead to significant benefits. It is therefore important to take steps to further raise such implementation and awareness among oncology team members in other geographic locations and clinical settings.

Estimation of recurrent atherosclerotic cardiovascular event risk in patients with established cardiovascular disease: the updated SMART2 algorithm.

AIMS: The 10-year risk of recurrent atherosclerotic cardiovascular disease (ASCVD) events in patients with established ASCVD can be estimated with the Secondary Manifestations of ARTerial disease (SMART) risk score, and may help refine clinical management. To broaden generalizability across regions, we updated the existing tool (SMART2 risk score) and recalibrated it with regional incidence rates and assessed its performance in external populations. METHODS AND RESULTS: Individuals with coronary artery disease, cerebrovascular disease, peripheral artery disease, or abdominal aortic aneurysms were included from the Utrecht Cardiovascular Cohort-SMART cohort [n = 8355; 1706 ASCVD events during a median follow-up of 8.2 years (interquartile range 4.2-12.5)] to derive a 10-year risk prediction model for recurrent ASCVD events (non-fatal myocardial infarction, non-fatal stroke, or cardiovascular mortality) using a Fine and Gray competing risk-adjusted model. The model was recalibrated to four regions across Europe, and to Asia (excluding Japan), Japan, Australia, North America, and Latin America using contemporary cohort data from each target region. External validation used data from seven cohorts [Clinical Practice Research Datalink, SWEDEHEART, the international REduction of Atherothrombosis for Continued Health (REACH) Registry, Estonian Biobank, Spanish Biomarkers in Acute Coronary Syndrome and Biomarkers in Acute Myocardial Infarction (BACS/BAMI), the Norwegian COgnitive Impairment After STroke, and Bialystok PLUS/Polaspire] and included 369 044 individuals with established ASCVD of whom 62 807 experienced an ASCVD event. C-statistics ranged from 0.605 [95% confidence interval (CI) 0.547-0.664] in BACS/BAMI to 0.772 (95% CI 0.659-0.886) in REACH Europe high-risk region. The clinical utility of the model was demonstrated across a range of clinically relevant treatment thresholds for intensified treatment options. CONCLUSION: The SMART2 risk score provides an updated, validated tool for the prediction of recurrent ASCVD events in patients with established ASCVD across European and non-European populations. The use of this tool could allow for a more personalized approach to secondary prevention based upon quantitative rather than qualitative estimates of residual risk.

Prognostic value of initial QRS analysis in anterior STEMI: Correlation with left ventricular systolic dysfunction, serum biomarkers, and cardiac outcomes.

BACKGROUND: The presence of pathologic Q waves on admission electrocardiogram (ECG) in patients with anterior ST-elevated myocardial infarction (STEMI) has been related to adverse cardiac outcomes. Our study evaluates the prognostic value of QRS complex and Q waves in patients with STEMI undergoing percutaneous coronary intervention. METHODS: We prospectively analyzed the specific characteristics of QRS complex and pathologic Q waves on admission and on discharge ECG in 144 patients hospitalized for anterior STEMI. We correlated these findings with the development of left ventricular systolic dysfunction (LVSD), appearance of heart failure (HF) or death during follow-up, and levels of several biomarkers obtained 6 months after the index event. RESULTS: Multivariate logistic regression analysis showed that QRS width (odds ratios [OR] 1.05, p = .001) on admission ECG and the sum of Q-wave depth (OR 1.06, p = .002) on discharge ECG were independent predictors of LVSD development. Moreover, QRS width on admission ECG was related to an increased risk of HF or death (OR 1.03, p = .026). Regarding biomarkers, QRS width on admission ECG revealed a statistically significant relationship with the levels of NT-pro-BNP at 6 months (0.29, p = .004); the sum of Q-wave depth (0.27, p = .012) and width (0.25, p = .021) on admission ECG was related to the higher levels of hs-cTnI; the sum of the voltages in precordial leads both on admission ECG (-0.26, p = .011) and discharge ECG (0.24, p = .046) was related to the lower levels of parathormone. CONCLUSIONS: Assessment of QRS complex width and pathologic Q waves on admission and discharge ECGs aids in predicting long-term prognosis in patients with STEMI.

Advanced interatrial block: An electrocardiographic marker for stroke recurrence.

The presence of interatrial block (IAB) has been directly related to the appearance of various atrial tachyarrhythmias and therefore could be a risk factor for stroke. The objective of this study is to establish whether the presence of IAB could predict stroke recurrence in patients with a previous episode. METHODS: We included all patients discharged from our hospital in 2011 following treatment for stroke, excluding those of cardioembolic or lacunar etiology. For all patients we analyzed the ECG recordings, determined whether the patient presented cardiovascular risk factors, and determined the presence and type of IAB. An IAB was defined as partial if the P-wave duration was ≥120 ms, and advanced if the duration was ≥120 ms and presented biphasic morphology in the inferior leads. The primary endpoint was the recurrence of stroke and the secondary endpoint was the incidence of atrial tachyarrhythmias after the first episode. RESULTS: A total of 149 patients were identified (80 (71.5-86.0) years, 41% men). After a median follow-up of 3.96 (0.63-5.35) years, 54 deaths (36%) were observed, 27 patients (18%) had experienced stroke recurrence, and 20 (13%) had developed atrial tachyarrhythmias. On multivariate analysis, the presence of advanced IAB [HR: 2.3, 95% CI (1.0-5.5); p = 0.043] and diabetes [HR: 2.5, 95% CI (1.1-5.4); p = 0.018] were significantly associated with stroke recurrence. CONCLUSION: The presence of advanced IAB predicts the recurrence of stroke in patients with a previous episode. Further studies should be performed to investigate possible interventions.

Circulating fibroblast growth factor-23 plasma levels predict adverse cardiovascular outcomes in patients with diabetes mellitus with coronary artery disease.

BACKGROUND: Abnormalities of fibroblast growth factor-23 (FGF-23) plasma levels predict adverse outcomes in patients with coronary artery disease. However, FGF-23 has a different behaviour in the presence of type 2 diabetes mellitus (T2D). We explored whether the presence of T2D affects the predictive power of FGF-23. METHODS: In 704 patients with stable coronary artery disease, FGF-23, calcidiol, parathormone (PTH) and phosphate plasma levels were prospectively assessed. The primary outcome was the development of acute ischemic events (acute coronary syndrome, stroke or transient ischemic attack), heart failure or death. RESULTS: One hundred seventy-three (24.6%) patients had T2D, without differences in age, sex or estimated glomerular filtration rate as compared with non-diabetic patients. Serum PTH was lower and phosphate higher in T2D than in non-diabetic patients, without differences in FGF-23 or calcidiol levels. During follow-up (2.15 ± 0.99 years), 26 (15.2%) T2D and 51 (9.6%) non-diabetic patients developed the outcome (p = 0.048). T2D patients who developed the outcome had higher FGF-23 [112.0 (59.9, 167.6) vs 68.9 (54.2, 93.0) RU/mL; p = 0.002], PTH [71.3 (47.3, 106.6) vs 51.9 (40.8, 66.2) pg/mL; p = 0.004) and phosphate (3.53 ± 0.71 vs 3.25 ± 0.50 mg/dL; p = 0.017) levels than T2D subjects who remained stable. These differences were not significant in non-diabetic patients. By multivariable Cox proportional hazard model, FGF-23 predicted independently the outcome in T2D patients [hazard ratio = 1.277; 95% CI (1.132, 1.442)] but not in those without T2D. CONCLUSIONS: FGF-23 plasma levels predict adverse cardiovascular outcomes in coronary artery disease patients who have T2D but not in those without T2D. This finding should be confirmed in larger studies. Copyright © 2016 John Wiley & Sons, Ltd.

Important abnormalities of bone mineral metabolism are present in patients with coronary artery disease with a mild decrease of the estimated glomerular filtration rate.

Chronic kidney disease (CKD)-mineral and bone disorder (MBD) is characterized by increased circulating levels of parathormone (PTH) and fibroblast growth factor 23 (FGF23), bone disease, and vascular calcification, and is associated with adverse outcomes. We studied the prevalence of mineral metabolism disorders, and the potential relationship between decreased estimated glomerular filtration rate (eGFR) and CKD-MBD in coronary artery disease patients in a cross-sectional study of 704 outpatients 7.5 ± 3.0 months after an acute coronary syndrome. The mean eGFR (CKD Epidemiology Collaboration formula) was 75.8 ± 19.1 ml/min/1.73 m(2). Our patients showed lower calcidiol plasma levels than a healthy cohort from the same geographical area. In the case of men, this finding was present despite similar creatinine levels in both groups and older age of the healthy subjects. Most patients (75.6 %) had an eGFR below 90 ml/min/1.73 m(2) (eGFR categories G2-G5), with 55.3 % of patients exhibiting values of 60-89 ml/min/1.73 m(2) (G2). PTH (r = -0.3329, p < 0.0001) and FGF23 (r = -0.3641, p < 0.0001) levels inversely correlated with eGFR, whereas calcidiol levels and serum phosphate levels did not. Overall, PTH levels were above normal in 34.9 % of patients. This proportion increased from 19.4 % in G1 category patients, to 33.7 % in G2 category patients and 56.6 % in G3-G5 category patients (p < 0.001). In multivariate analysis, eGFR and calcidiol levels were the main independent determinants of serum PTH. The mean FGF23 levels were 69.9 (54.6-96.2) relative units (RU)/ml, and 33.2 % of patients had FGF23 levels above 85.5 RU/ml (18.4 % in G1 category patients, 30.0 % in G2 category patients, and 59.2 % in G3-G5 category patients; p < 0.001). In multivariate analysis, eGFR was the main predictor of FGF23 levels. Increased phosphate levels were present in 0.7 % of the whole sample: 0 % in G1 category patients, 0.3 % in G2 category patients, and 2.8 % in G3-G5 category patients (p = 0.011). Almost 90 % of patients had calcidiol insufficiency without significant differences among the different degrees of eGFR. In conclusion, in patients with coronary artery disease there is a large prevalence of increased FGF23 and PTH levels. These findings have an independent relationship with decreased eGFR, and are evident at an eGFR of 60-89 ml/min/1.73 m(2). Then, mild decreases in eGFR must be taken in consideration by the clinician because they are associated with progressive abnormalities of mineral metabolism.

The Prognostic Value of High-Sensitive Troponin I in Stable Coronary Artery Disease Depends on Age and Other Clinical Variables.

OBJECTIVES: To study the prognostic value of high-sensitive troponin (hs-cTn) I in stable coronary artery disease. METHODS: In total, we studied 705 patients. Secondary outcomes were the incidence of: (1) acute ischemic events and (2) heart failure or death. The primary outcome was the composite of them. RESULTS: Patients with hs-cTnI >0 ng/ml (62.1%) were older, had a lower estimated glomerular filtration rate, more frequent a history of hypertension, atrial fibrillation, ejection fraction <40%, and therapy with angiotensin-converting enzyme inhibitors, diuretics and acenocumarol. The follow-up period was 2.2 ± 0.99 years. Fifty-three patients suffered an acute ischemic event, 33 died or suffered heart failure and 78 developed the primary outcome. By univariate Cox's regression analysis, hs-cTnI >0 was associated with a higher risk of developing the primary outcome [relative risk = 2.360 (1.359-4.099); p = 0.001] and heart failure or death [relative risk = 5.932 (1.806-19.482); p < 0.001], but not with acute ischemic events. Statistical significance was lost after controlling for age. By logistic regression analysis, age [relative risk = 1.026 (1.009-1.044); p = 0.003], ejection fraction <40% [relative risk = 4.099 (2.043-8.224); p < 0.001], use of anticoagulants [relative risk = 2.785 (1.049-7.395); p = 0.040] and therapy with angiotensin-converting enzyme inhibitors [relative risk = 1.471 (1.064-2.034); p = 0.020], and estimated glomerular filtration rate [relative risk = 0.988 (0.977-0.999); p = 0.027] were associated with hs-cTnI >0. CONCLUSIONS: In stable coronary disease, hs-cTnI is associated with the incidence of heart failure or death, but this relationship depends on other variables.

Non-coronary atherosclerosis: a marker of poor prognosis in patients undergoing coronary artery bypass surgery.

Introduction: The presence of non-coronary atherosclerosis (NCA) in patients with coronary artery disease is associated with a poor prognosis. We have studied whether NCA is also a predictor of poorer outcomes in patients undergoing coronary artery bypass grafting (CABG). Materials and methods: This is an observational study involving 567 consecutive patients who underwent CABG. Variables and prognosis were analysed based on the presence or absence of NCA, defined as previous stroke, transient ischaemic attack (TIA), or peripheral artery disease (PAD) [lower extremity artery disease (LEAD), carotid disease, previous lower limb vascular surgery, or abdominal aortic aneurysm (AAA)]. The primary outcome was a combination of TIA/stroke, acute myocardial infarction, new revascularization procedure, or death. The secondary outcome added the need for LEAD revascularization or AAA surgery. Results: One-hundred thirty-eight patients (24%) had NCA. Among them, traditional cardiovascular risk factors and older age were more frequently present. At multivariate analysis, NCA [hazard ratio (HR) = 1.84, 95% confidence interval (CI) 1.27-2.69], age (HR = 1.35, 95% CI 1.09-1.67, p = 0.004), and diabetes mellitus (HR = 1.50, 95% CI 1.05-2.15, p = 0.025), were positively associated with the development of the primary outcome, while estimated glomerular filtration rate (HR = 0.86, 95% CI 0.80-0.93, p = 0.001) and use of left internal mammary artery (HR = 0.36, 95% CI 0.15-0.82, p = 0.035), were inversely associated with this outcome. NCA was also an independent predictor of the secondary outcome. Mortality was also higher in NCA patients (27.5% vs. 9%, p < 0.001). Conclusions: Among patients undergoing CABG, the presence of NCA doubled the risk of developing cardiovascular events, and it was associated with higher mortality.

Serum Biomarkers and Their Association with Myocardial Function and Exercise Capacity in Cardiac Transthyretin Amyloidosis.

BACKGROUND: Transthyretin cardiac amyloidosis (ATTR amyloidosis) is a frequent etiology of heart failure. Inflammation and mineral metabolism are associated with myocardial dysfunction and clinical performance. Cardiac global longitudinal strain (GLS) allows function assessment and is associated with prognosis. Our aim was to describe possible correlations between GLS, biomarker levels and clinical performance in ATTR amyloidosis. METHODS: Thirteen patients with ATTR amyloidosis were included. Clinical characteristics; echocardiographic features, including strain assessment and 6 min walk test (6MWT); and baseline inflammatory, mineral metabolism and cardiovascular biomarker levels were assessed. RESULTS: Of the 13 patients, 46.2% were women, and the mean age was 79 years. TAPSE correlated with NT-ProBNP (r -0.65, p < 0.05) and galectin-3 (r 0.76, p < 0.05); E/E' ratio correlated with hsCRP (r 0.58, p < 0.05). Left ventricular GLS was associated with NT-ProBNP (r 0.61, p < 0.05) (patients have a better prognosis if the strain value is more negative) and left atrial GLS with NT-ProBNP (r -0.73, p < 0.05) and MCP1 (r 0.55, p < 0.05). Right ventricular GLS was correlated with hsTnI (r 0.62, p < 0.05) and IL6 (r 0.881, p < 0.05). Klotho levels were correlated with 6MWT (r 0.57, p < 0.05). CONCLUSIONS: While inflammatory biomarkers were correlated with cardiac function, klotho levels were associated with clinical performance in the population with TTR-CA.

Fibroblast growth factor 23 independently predicts adverse outcomes after an acute coronary syndrome.

AIMS: Abnormalities of mineral metabolism (MM) have been related to cardiovascular disorders. There are no reports on the prognostic role of MM after an acute coronary syndrome (ACS). We aim to assess the prognostic role of MM after an ACS. METHODS AND RESULTS: Plasma levels of components of MM [fibroblast growth factor 23 (FGF23), calcidiol, parathormone, klotho, and phosphate], high-sensitivity C-reactive protein, and N-terminal-pro-brain natriuretic peptide were measured in 1190 patients at discharge from an ACS. The primary outcome was a combination of acute ischaemic events, heart failure (HF) and death. Secondary outcomes were the separate components of the primary outcome. Age was 61.7 ± 12.2 years, and 77.1% were men. Median follow-up was 5.44 (3.03-7.46) years. Two hundred and ninety-four patients developed the primary outcome. At multivariable analysis FGF23 (hazard ratio, HR 1.18 [1.08-1.29], P < 0.001), calcidiol (HR 0.86 [0.74-1.00], P = 0.046), previous coronary or cerebrovascular disease, and hypertension were independent predictors of the primary outcome. The predictive power of FGF23 was homogeneous across different subgroups of population. FGF23 (HR 1.45 [1.28-1.65], P < 0.001) and parathormone (HR 1.06 1.01-1.12]; P = 0.032) resulted as independent predictors of HF. FGF23 (HR 1.21 [1.07-1.37], P = 0.002) and calcidiol (HR 0.72 [0.54-0.97), P = 0.028) were independent predictors of death. No biomarker predicted acute ischaemic events. FGF23 predicted independently the primary outcome in patients with estimated glomerular filtration rate > 60 mL/min/1.73 m2 . CONCLUSIONS: FGF23 and other components of MM are independent predictors of HF and death after an ACS. This effect is homogeneous across different subgroups of population, and it is not limited to patients with chronic kidney disease.

Cardiac Rehabilitation Increases Plasma Klotho Levels.

Background: Mineral metabolism (MM), mainly fibroblast growth factor-23 (FGF-23) and klotho, has been linked to cardiovascular (CV) diseases. Cardiac rehabilitation (CR) has been demonstrated to reduce CV events, although its potential relationship with changes in MM is unknown. Methods: We performed a prospective, observational, case-control study, with acute coronary syndrome (ACS) patients who underwent CR and control patients (matched by age, gender, left ventricular ejection fraction, diabetes, and coronary artery bypass grafting), who did not. The inclusion dates were from August 2013 to November 2017 in CR group and from July 2006 to June 2014 in control group. Clinical, biochemical, and MM biomarkers were collected at discharge and six months later. Our objective was to evaluate differences in the modification pattern of MM in both groups. Results: We included 58 CR patients and 116 controls. The control group showed a higher prevalence of hypertension (50.9% vs. 34.5%), ST-elevated myocardial infarction (59.5% vs. 29.3%), and treatment with angiotensin-converting enzyme inhibitors (100% vs. 69%). P2Y12 inhibitors and beta-blockers were more frequently prescribed in the CR group (83.6% vs. 96.6% and 82.8% vs. 94.8%, respectively). After six months, klotho levels increased in CR patients whereas they were reduced in controls (+63 vs. -49 pg/mL; p < 0.001). FGF-23 was unchanged in the CR group and reduced in controls (+0.2 vs. -17.3 RU/dL; p < 0.003). After multivariate analysis, only the change in klotho levels was significantly different between groups (+124 pg/mL favoring CR group; IC 95% [+44 to +205]; p = 0.003). Conclusions: In our study, CR after ACS increases plasma klotho levels without significant changes in other components of MM. Further studies are needed to clarify whether this effect has a causal role in the clinical benefit of CR.

Absence of High Lipoprotein(a) Levels Is an Independent Predictor of Acute Myocardial Infarction without Coronary Lesions.

The pathophysiological mechanisms underlying Myocardial Infarction with Non-Obstructive Coronary Artery Disease (MINOCA) are still under debate. Lipoprotein (a) [Lp(a)] has proinflammatory and prothrombotic actions and has been involved in the pathogenesis of atherosclerosis. However, no previous studies have linked Lp(a) levels with the probability of developing MINOCA. Moreover, the relationship between MINOCA and the plasma levels of other proatherogenic and proinflammatory molecules such as Interleukin-18 (IL18) and proprotein convertase subtilisin/kexin type 9 (PCSK9) has not been studied. We conducted a prospective, multicenter study involving 1042 patients with acute myocardial infarction (AMI). Seventy-six patients had no significant coronary lesions. All patients underwent plasma analysis on admission. MINOCA patients were younger (57 (47-68) vs. 61 (52-72) years; p = 0.010), more frequently female (44.7% vs. 21.0%; p < 0.001), and had lower rates of diabetes and of Lp(a) > 60 mg/dL (9.2% vs. 19.8%; p = 0.037) than those with coronary lesions; moreover, High Density Lipoprotein cholesterol (HDL-c) levels were higher in MINOCA patients. The absence of Lp(a) > 60 mg/dL and of diabetes were independent predictors of MINOCA, as well as female sex, high HDL-c levels, and younger age. IL-18 and PCSK9 levels were not predictors of MINOCA. During a follow-up of 5.23 (2.89, 7.37) years, the independent predictors of the primary outcome (acute ischemic events or death) in the whole sample were Lp(a) > 60 mg/dL, older age, low estimated Glomerular Filtration rate (eGFR), hypertension, previous heart failure (HF), coronary artery bypass graft, use of insulin, and no therapy with acetylsalicylic acid. In conclusion, in AMI patients, the absence of high Lp(a) levels, as well high HDL-c levels, were independent predictors of the inexistence of coronary artery disease. High Lp (a) levels were also an independent predictor of ischemic events or death.

The role of bioimpedance analysis in overweight and obese patients with acute heart failure: a pilot study.

AIMS: Residual congestion at the time of hospital discharge is an important readmission risk factor, and its detection with physical examination and usual diagnostic techniques have strong limitations in overweight and obese patients. New tools like bioelectrical impedance analysis (BIA) could help to determine when euvolaemia is reached. The aim of this study was to investigate the usefulness of BIA in management of heart failure (HF) in overweight and obese patients. METHODS AND RESULTS: Our study is a single-centre, single-blind, randomized controlled trial that included 48 overweight and obese patients admitted for acute HF. The study population was randomized into two arms: BIA-guided group and standard care. Serum electrolytes, kidney function, and natriuretic peptides were followed up during their hospital stay and at 90 days after discharge. The primary endpoint was development of severe acute kidney injury (AKI) defined as an increase in serum creatinine by >0.5 mg/dL during hospitalization, and the main secondary endpoint was the reduction of N-terminal pro-brain natriuretic peptide (NT-proBNP) levels during hospitalization and within 90 days after discharge. The BIA-guided group showed a remarkable lower incidence of severe AKI, although no significant differences were found (41.4% vs. 16.7%; P = 0.057). The proportion of patients who achieved levels of NT-proBNP < 1000 pg/mL at 90 days was significantly higher in the BIA-guided group than in the standard group (58.8% vs. 25%; P = 0.049). No differences were observed in the incidence of adverse outcomes at 90 days. CONCLUSIONS: Among overweight and obese patients with HF, BIA reduces NT-proBNP levels at 90 days compared with standard care. In addition, there is a trend towards lower incidence of AKI in the BIA-guided group. Although more studies are required, BIA could be a useful tool in decompensated HF management in overweight and obese patients.

Personalized Therapy and Clinical Outcome for Heart Failure.

Heart failure (HF) is a complex clinical syndrome that results from the structural and/or functional impairment of systolic function or ventricular filling, which in turn causes elevated intracardiac pressure and/or inadequate cardiac output at rest and/or during exercise [...].

Enhancing knowledge and awareness of transthyretin cardiac amyloidosis and shared decision-making among cardiology team members in Colorado, USA via an online educational initiative.

OBJECTIVES: Our project aimed to increase knowledge of noninvasive diagnostic modalities (including bone radiotracer scintigraphy), raise suspicion of transthyretin cardiac amyloidosis (ATTR-CA), and improve cardiology team member's awareness and knowledge of shared decision-making (SDM), as well as the quality of SDM communication between cardiology team members and patients. METHODS: An online educational module and survey was developed and cardiology team members in Colorado, USA, were invited to participate. This online educational module included various important topics related to ATTR-CA (e.g., the cause of ATTR-CA, endomyocardial biopsy, and noninvasive methods to diagnose ATTR-CA) and SDM (e.g., benefits of SDM, the role of SDM in the diagnosis of ATTR-CA, implementation of SDM in cardiology practice, and the 3-talk model). RESULTS: There were 34 survey respondents, over one-third of whom were cardiologists. Most respondents agreed on the importance of diagnosing ATTR-CA at an early stage, and about three-quarters of the survey takers agreed that bone scintigraphy can reliably diagnose ATTR-CA without the need for endomyocardial biopsy. Concern over increased time commitment was the leading barrier to the implementation of SDM in respondents' clinical practice. The majority of respondents identified the correct answer regarding ATTR-CA and SDM after reading the online educational module. This improvement in scores after exposure to the online educational module was statistically significant. CONCLUSION: Baseline knowledge and awareness of various issues related to ATTR-CA was relatively low among cardiology team members. Participants' knowledge was enhanced through our effective online educational program. Prospective educational projects focused on various methods of detecting ATTR-CA as well as other amyloid conditions in diverse clinical settings will remain important.

Prevalence and prognostic value of monoclonal gammopathy in heart failure patients with preserved ejection fraction: A prospective study.

BACKGROUND: Heart failure (HF) with preserved ejection fraction (HFpEF) and monoclonal gammopathy of uncertain significance (MGUS) are two entities that share pathophysiological mechanisms. The aim herein, was to assess the prevalence of MGUS in patients with HFpEF and no left ventricular (LV) hypertrophy, as well as its association with a pre-specified clinical endpoint at 12 months. METHODS: The present study prospectively enrolled 69 patients admitted with HF, with ejection fraction ≥ 50%, and LV wall thickness < 12 mm. All patients were screened for MGUS. Clinical events were determined over a 12 month follow-up. The pre-specified composite clinical endpoint was readmission for HF or death. RESULTS: The prevalence of MGUS in this population was 13%. There were no differences in the incidence of the composite clinical endpoint between patients with and without MGUS. Multivariate analysis showed that treatment with angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) was associated with fewer clinical events (HR: 0.153, 95% CI: 0.037-0.622, p = 0.009) and indicated a trend to lower risk of readmission for HF and death. Beta-blockers were associated with lower rates of the composite clinical endpoint (HR: 0.192, 95% CI: 0.05-0.736, p = 0.016), readmission for HF (HR: 0.272, 95% CI: 0.087-0.851, p = 0.025) and indicated a trend to lower mortality. Moreover, potassium serum levels > 5 mEq/L were associated with higher rates of the composite endpoint (HR: 6.074, 95% CI: 1.6-22.65, p = 0.007). CONCLUSIONS: The prevalence of MGUS in patients with HFpEF without hypertrophy was 3-fold that of the general population. There was no significant correlation between clinical outcomes and the presence of MGUS. Beta-blockers and ACEIs/ARBs reduced the composite of mortality and readmissions for HF in HFpEF patients. Hyperpotassemia was related to worse prognosis.

NT-proBNP Levels Influence the Prognostic Value of Mineral Metabolism Biomarkers in Coronary Artery Disease.

Background. Mineral metabolism (MM) system and N-terminal pro-brain natriuretic peptide (NT-ProBNP) have been shown to add prognostic value in patients with stable coronary artery disease (SCAD). However, the influence of NT-ProBNP on the prognostic role of MM in patients with SCAD has not been shown yet. The objective of this study is to assess the influence of NT-ProBNP on the prognostic role of MM markers in patients with SCAD. Methods: We analyzed the prognostic value of MM markers (parathormone (PTH), klotho, phosphate, calcidiol (25-hydroxyvitamin D3), and fibroblast growth factor-23) in 964 patients with SCAD and NT-ProBNP > 125 pg/mL vs. patient with NT-ProBNP ≤ 125 pg/mL included in five hospitals in Spain. The main outcome was the combination of death, heart failure, and ischemic events (any acute coronary syndrome, ischemic stroke, or transient ischemic attack). Results: A total of 622 patients had NT-proBNP > 125 pg/mL and 342 patients had NT-ProBNP ≤ 125 pg/mL. The median follow-up was 5.1 years. In the group of NT-proBNP > 125 pg/mL, the patients were older, and there were more females and smokers than in the group of patients with normal NT-proBNP. Additionally, the proportion of patients with hypertension, atrial fibrillation, ejection fraction < 40%, cerebrovascular attack, or prior coronary artery bypass graft was higher in the high NT-proBNP group. In the high NT-proBNP patients, the predictors of poor prognosis were PTH (HR = 1.06 (1.01−1.10), p < 0.001) and NT-proBNP (HR = 1.02 (1.01−1.03), p = 0.011), along with age (HR = 1.039 (1.02−1.06), p < 0.001), prior coronary artery bypass graft (HR = 1.624 (1.02−2.59), p = 0.041), treatment with statins (HR = 0.32 (0.19−0.53), p < 0.001), insulin (HR = 2.49 (1.59−4.09), p < 0.001), angiotensin receptor blockers (HR = 1.73 (1.16−2.56), p = 0.007), nitrates (HR = 1.65 (1.10−2.45), p = 0.014), and proton pump inhibitors (HR = 2.75 (1.74−4.36), p < 0.001). In the NT-proBNP ≤ 125 pg/mL subgroup, poor prognosis predictors were plasma levels of non-high-density lipoprotein (non-HDL) cholesterol (HR = 1.01 (1.00−1.02), p = 0.014) and calcidiol (HR = 0.96 (0.92−0.99), p = 0.045), as well as treatment with verapamil (HR = 11.28 (2.54−50.00), p = 0.001), and dihydropyridines (HR = 3.16 (1.63−6.13), p = 0.001). Conclusion: In patients with SCAD and NT-ProBNP > 125 pg/mL, PTH and NT-ProBNP, which are markers related to ventricular damage, are predictors of poor outcome. In the subgroup of patients with NT-ProBNP ≤ 125 pgm/L, calcidiol and non-HDL cholesterol, which are more related to vascular damage, are the independent predictors of poor outcome. Then, in patients with SCAD, baseline NT-ProBNP may influence the type of biomarker that is effective in risk prediction.

Impact of renal function on the prognostic value of mineral metabolism in patients with chronic ischaemic heart disease patients with chronic ischaemic heart disease. / Impacto de la función renal en el valor pronóstico del metabolismo mineral en pacientes con cardiopatía isquémica crónica.

BACKGROUND: Parathormone (PTH) is a component of the Mineral Metabolism (MM) system that has been shown recently to add prognostic value in pts. with stable coronary artery disease (SCAD) and average renal function. However, the influence of renal function on the prognostic role of PTH in pts. with SCAD has not been shown yet. PURPOSE: To assess the influence of estimated glomerular filtration rate (eGFR) on the prognostic role of PTH and other MM markers in pts. with SCAD. METHODS: We analyzed the prognostic value of MM markers (PTH, klotho, phosphate, calcidiol [25-hydroxyvitamin D], and fibroblast growth factor-23 [FGF23]) in 964 pts. with SCAD and eGFR<60ml/min/1.73 m2 (LGFR) vs pts. with eGFR≥60ml/min/1.73 m2 (HGFR) included in five hospitals of Madrid. The main outcome was the combination of death with ischemic events (any acute coronary syndrome, ischemic stroke or transient ischemic attack). eGFR was calculated by the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI). RESULTS: Age was 60.0 (52.0-72.0) years, 76.2% of patients were men, and eGFR was 80.4 (65.3-93.1) ml/min/1,73 m2. Median follow-up was 5.39 (2.81-6.92) years. There were 790 pts. with HGFR and 174 with LGFR. In HGFR pts., predictors of ischemic events or death were plasma levels of calcidiol [HR=0.023 (0.94-0.99) p=0.023], FGF23 [HR=1.00 (1.00-1.003) p=0.036], non-HDL cholesterol [HR=1.01 (1.00-1.01) p=0.026] and high sensitivity troponin I [HR=5.12 (1.67-15.59) p=0.004], along with age [HR=1.03 (1.01-1.05) p=0.01], treatment with statins [HR=0.36 (0.19-0.68) p=0.002], nitrates [HR=1.13 (1.07-2.79) p=0.027], dihydropyridines [HR=1.71 (1.05-2.77) p=0.032], verapamil [HR=5.71 (1.35-24.1) p=0.018], and proton-pump inhibitors [HR=2.23 (1.36-3.68) p= 0.002]. In the LGFR subgroup, predictors of death or ischemic events were PTH plasma levels, [HR=1.01 (1.00-1.01) p=0.005], eGFR [HR=0.96 (0.94-0.99) p=0.004], age [HR=1.06 (1.02-1.10) p=0.003], caucasian race [HR=0.04 (0.004-0.380) p=0.005], and treatment with insulin [HR=2.6 (1.20-5.63) p=0.015]. CONCLUSIONS: In pts. with SCAD, PTH is an independent predictor of poor outcomes only in those with eGFR<60ml/min/1.73 m2, while in pts. with eGFR≥60ml/min/1.73 m2 calcidiol and FGF23 become the only components of MM that may predict prognosis. Then, renal function influences the predictive power of MM markers in pts. with SCAD.
