Multidisciplinary Management of Patients With Chronic Obstructive Pulmonary Disease and Cardiovascular Disease.

Chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) frequently coexist, increasing the prevalence of both entities and impacting on symptoms and prognosis. CVD should be suspected in patients with COPD who have high/very high risk scores on validated scales, frequent exacerbations, precordial pain, disproportionate dyspnea, or palpitations. They should be referred to cardiology if they have palpitations of unknown cause or angina pain. COPD should be suspected in patients with CVD if they have recurrent bronchitis, cough and expectoration, or disproportionate dyspnea. They should be referred to a pulmonologist if they have rhonchi or wheezing, air trapping, emphysema, or signs of chronic bronchitis. Treatment of COPD in cardiovascular patients should include long-acting muscarinic receptor antagonists (LAMA) or long-acting beta-agonists (LABA) in low-risk or high-risk non-exacerbators, and LAMA/LABA/inhaled corticosteroids in exacerbators who are not controlled with bronchodilators. Cardioselective beta-blockers should be favored in patients with CVD, the long-term need for amiodarone should be assessed, and antiplatelet drugs should be maintained if indicated.

Identifying the patient with heart failure to be treated with vericiguat.

The pathophysiology of heart failure with reduced ejection fraction (HFrEF) is a complex process in which a number of neurohormonal systems are involved. Targeting only some of these systems, but not all, translates into a partial benefit of HF treatment. The nitric oxide-soluble guanylate cyclase (sGC)-cGMP pathway is impaired in HF, leading to cardiac, vascular and renal disturbances. Vericiguat is a once-daily oral stimulator of sGC that restores this system. No other disease-modifying HF drugs act on this system. Despite guidelines recommendations, a substantial proportion of patients are not taking all recommended drugs or when taking them, they do so at low doses, limiting their potential benefits. In this context, treatment should be optimized considering different parameters, such as blood pressure, heart rate, renal function, or potassium, as they may interfere with their implementation at the recommended doses. The VICTORIA trial showed that adding vericiguat to standard therapy in patients with HFrEF significantly reduced the risk of cardiovascular death or HF hospitalization by 10% (NNT 24). Furthermore, vericiguat does not interfere with heart rate, renal function or potassium, making it particularly useful for improving the prognosis of patients with HFrEF in specific settings and clinical profiles.

Optimizing the management of patients with worsening heart failure: beyond heart failure hospitalization.

INTRODUCTION: Worsening heart failure (HF) is associated with a high risk of death and HF hospitalization. AREAS COVERED: A systematic search was conducted on PubMed (MEDLINE), using the MeSH terms [Heart failure] + [Worsening] + [Treatment] + [Vulnerable period] up to February 2023. Original data from clinical trials, and observational studies were critically analyzed. EXPERT OPINION: Although the vulnerable period has been traditionally limited to the first 6 months after HF hospitalization, the fact is that there are other clinical scenarios in which the patient is particularly vulnerable. These vulnerable patients may also include those that require parenteral administration of diuretics in the day hospital or emergency department, those in which the increase of oral diuretic dose in an outpatient setting is needed to relief congestive symptoms, as well as those that remain symptomatic despite treatment. On the other hand, HF is a complex disease in which different neurohormonal systems are involved. Therefore, to actually reduce the HF burden, a comprehensive management, targeting all the neurohormonal systems that are involved in the pathogenesis of HF, through the use of those drugs that have demonstrated to positively modify the clinical course of HF, is needed.

Serum potassium dynamics during acute heart failure hospitalization.

BACKGROUND: Available information about prognostic implications of potassium levels alteration in the setting of acute heart failure (AHF) is scarce. OBJECTIVES: We aim to describe the prevalence of dyskalemia (hypo or hyperkalemia), its dynamic changes during AHF-hospitalization, and its long-term clinical impact after hospitalization. METHODS: We analyzed 1779 patients hospitalized with AHF who were included in the REDINSCOR II registry. Patients were classified in three groups, according to potassium levels both on admission and discharge: hypokalemia (potassium < 3.5 mEq/L), normokalemia (potassium = 3.5-5.0 mEq/L and, hyperkalemia (potassium > 5 mEq/L). RESULTS: The prevalence of hypokalemia and hyperkalemia on admission was 8.2 and 4.6%, respectively, and 6.4 and 2.7% at discharge. Hyperkalemia on admission was associated with higher in-hospital mortality (OR = 2.32 [95% CI: 1.04-5.21] p = 0.045). Among patients with hypokalemia on admission, 79% had normalized potassium levels at discharge. In the case of patients with hyperkalemia on admission, 89% normalized kalemia before discharge. In multivariate Cox regression, dyskalemia was associated with higher 12-month mortality, (HR = 1.48 [95% CI, 1.12-1.96], p = 0.005). Among all patterns of dyskalemia persistent hypokalemia (HR = 3.17 [95% CI: 1.71-5.88]; p < 0.001), and transient hyperkalemia (HR = 1.75 [95% CI: 1.07-2.86]; p = 0.023) were related to reduced 12-month survival. CONCLUSIONS: Potassium levels alterations are frequent and show a dynamic behavior during AHF admission. Hyperkalemia on admission is an independent predictor of higher in-hospital mortality. Furthermore, persistent hypokalemia and transient hyperkalemia on admission are independent predictors of 12-month mortality.

Administration of Subcutaneous Furosemide in Elastomeric Pump vs. Oral Solution for the Treatment of Diuretic Refractory Congestion.

INTRODUCTION: The most common symptom in heart failure (HF) is congestion, which can be refractory to diuretic treatment. AIM: To verify whether, in patients with advanced HF and diuretic resistance, subcutaneous furosemide or furosemide in an oral solution can improve the clinical-analytical status. METHODS: From 2018 to 2020, 27 consecutive outpatients with diuretic resistance, not candidates for other alternatives, were recruited. Patients were treated either with subcutaneous furosemide in elastomeric pump (n: 10) or with oral solution (n: 17) for 5 days. RESULTS: The functional status (NYHA) improved with subcutaneous administration (predose: 3.8 ± 0.5 vs. postdose: 3.1 ± 0.7; p: 0.02) and oral solution (predose: 3.7 ± 0.3 vs. postdose: 2.5 ± 0.7; p: 0.0001). Weight loss was greater with the oral solution (predose: 85.5 ± 19.5 vs. postdose: 81.3 ± 18.8Kg; p: 0.0001) than subcutaneous (predose: 81.6 ± 15.9 vs. postdose: 80.4 ± 15.1kg; p: 0.16). Creatinine showed a non-significant increase in both groups. The number of hospital visits showed no difference between both options. CONCLUSIONS: The administration of furosemide, both subcutaneously by elastomeric pump or drinking the oral solution, is effective for the treatment of congestion in advanced HF refractory to diuretic treatment.

Rehospitalization burden and morbidity risk in patients with heart failure with mid-range ejection fraction.

AIMS: Heart failure with mid-range ejection fraction (HFmrEF) has been proposed as a distinct HF phenotype, but whether patients on this category fare worse, similarly, or better than those with HF with reduced EF (HFrEF) or preserved EF (HFpEF) in terms of rehospitalization risks over time remains unclear. METHODS AND RESULTS: We prospectively included 2961 consecutive patients admitted for acute HF (AHF) in our institution. Of them, 158 patients died during the index admission, leaving the sample size to be 2803 patients. Patients were categorized according to their EF: HFrEF if EF ≤ 40% (n = 908, 32.4%); HFmrEF if EF = 41-49% (n = 449, 16.0%); and HFpEF if EF ≥ 50% (n = 1446, 51.6%). Covariate-adjusted incidence rate ratios (IRRs) were used to evaluate the association between EF status and recurrent all-cause and HF-related admissions. At a median follow-up of 2.6 years (inter-quartile range: 1.0-5.3), 1663 (59.3%) patients died, and 6035 all-cause readmissions were registered in 2026 patients (72.3%), 2163 of them HF related. Rates of all-cause readmission per 100 patients-years of follow-up were 150.1, 176.9, and 163.6 in HFrEF, HFmrEF, and HFpEF, respectively (P = 0.097). After multivariable adjustment, when compared with that of patients with HFrEF and HFpEF, HFmrEF status was not significantly associated with a different risk of all-cause readmissions (IRR = 0.99; 95% confidence interval [CI], 0.77-1.27; P = 0.926; and IRR = 0.93; 95% CI, 0.74-1.18; P = 0.621, respectively) or HF-related readmissions (IRR = 1.06; 95% CI, 0.77-1.46; P = 0.725; and IRR = 1.11; 95% CI, 0.82-1.50; P = 0.511, respectively). CONCLUSIONS: Following an admission for AHF, patients with HFmrEF had a similar rehospitalization burden and a similar risk of recurrent all-cause and HF-related admissions than had patients with HFrEF or HFpEF. Regarding morbidity risk, HFmrEF seems not to be a distinct HF phenotype.

Procedural, Functional and Prognostic Outcomes Following Recanalization of Coronary Chronic Total Occlusions. Results of the Iberian Registry.

INTRODUCTION AND OBJECTIVES: There is current controversy regarding the benefits of percutaneous recanalization (PCI) of chronic total coronary occlusions (CTO). Our aim was to determine acute and follow-up outcomes in our setting. METHODS: Two-year prospective registry of consecutive patients undergoing PCI of CTO in 24 centers. RESULTS: A total of 1000 PCIs of CTO were performed in 952 patients. Most were symptomatic (81.5%), with chronic ischemic heart disease (59.2%). Previous recanalization attempts had been made in 15%. The mean SYNTAX score was 19.5 ± 10.6 and J-score was > 2 in 17.3%. A retrograde procedure was performed in 92 patients (9.2%). The success rate was 74.9% and was higher in patients without previous attempts (82.2% vs 75.2%; P = .001), those with a J-score ≤ 2 (80.5% vs 69.5%; P = .002), and in intravascular ultrasound-guided PCI (89.9% vs 76.2%, P = .001), which was an independent predictor of success. In contrast, severe calcification, length > 20mm, and blunt proximal cap were independent predictors of failed recanalization. The rate of procedural complications was 7.1%, including perforation (3%), myocardial infarction (1.3%), and death (0.5%). At 1-year of follow-up, 88.2% of successfully revascularized patients showed clinical improvement (vs 34.8%, P < .001), which was associated with lower mortality. At 1-year of follow-up, the mortality rate was 1.5%. CONCLUSIONS: Compared with other national registries, patients in the Iberian registry undergoing PCI of a CTO showed similar complexity, success rate, and complications. Successful recanalization was strongly associated with functional improvement, which was related to lower mortality.

Comparación de la eficacia y seguridad de flecainida y dronedarona como terapias antiarrítmicas para mantenimiento de ritmo sinusal en fibrilación auricular / Comparison of the efficacy and safety of dronedarone and flecainide as maintenance antiarrhythmic therapy for sinus rhythm in atrial fibrillation

Resumen Introducción y objetivos: Dronedarona y flecainida son antiarrítmicos de primera elección para reducir recurrencias de fibrilación auricular (FA), sin existir estudios que los comparen entre sí. Nuestro objetivo es comparar la eficacia en cuanto a prevención de recurrencias y seguridad de ambos fármacos. Métodos: Estudio retrospectivo en el que se incluyeron 123 pacientes de forma consecutiva en tratamiento con flecainida o dronedarona desde octubre de 2010 hasta febrero de 2013 por FA paroxística (76.4%) y FA persistente (23.6%). Se realizó cardioversión eléctrica en un 7.3% de los pacientes y farmacológica en un 16.3%. La mediana (rango intercuartílico) de seguimiento fue de 301 días (92-474), con una media de 2.8 revisiones por paciente. Se realizó análisis de tiempo hasta el primer evento mediante Kaplan-Meier y regresión de Cox ajustada por un índice de propensión. Resultados: De entre los 123 sujetos incluidos con FA, 71 fueron tratados con flecainida y 52 con dronedarona. Durante el seguimiento se registraron 36 recurrencias y 20 efectos adversos. Se documentaron un 36.6% de recurrencias en los pacientes tratados con flecainida en comparación con un 21% en los tratados con dronedarona (p = 0.073). En el análisis multivariante, dronedarona se mostró al menos tan eficaz como flecainida para prevenir recurrencias de FA (HR: 0.53, IC 95%: 0.20-1.44, p = 0.221) y demostró un perfil de seguridad comparable al de flecainida (HR: 0.68, IC 95%: 0.18-2.53, p = 0.566). Conclusiones: Según nuestra experiencia, dronedarona resulta al menos tan eficaz como flecainida para el mantenimiento de ritmo sinusal, con un buen perfil de tolerabilidad, a pesar de pautarse en pacientes con un perfil clínico más desfavorable.

Abstract Introduction and objectives: Dronedarone and flecainide are the first pharmacological choice to reduce recurrence of atrial fibrillation (AF); however, there are no studies comparing them. A study was performed to compare the efficacy in terms of recurrence of AF and safety of both drugs. Methods: A retrospective cohort study was conducted that included 123 consecutive patients treated with flecainide or dronedarone due to paroxysmal AF (76.4%) or persistent AF (23.6%), from October 2010 to February 2013. Electrical cardioversion was performed in 7.3% of patients and pharmacological cardioversion in 16.3%. The median (interquartile range) follow-up was 301 days (92-474) with a mean of 2.8 reviews per patient. Time to first event analysis was performed using Kaplan-Meier and Cox regression, adjusted for propensity score. Results: Of the 123 consecutive patients with AF included, 71 were on dronedarone and 52 on flecainide. During the follow-up, there were 36 AF recurrences and 20 safety events. There were recurrences in 36.6% of patients treated with flecainide, compared with 21% of those receiving dronedarone (P = .073). Dronedarone showed to be at least as effective as flecainide in preven- ting recurrence of atrial fibrillation (HR: 0.53, 95% CI: 0.20-1.44, P = .221), and demonstrated an acceptable safety profile when compared with flecainide (HR: 0.68, 95% CI: 0.18-2.53, P = .566). Conclusions: In our experience, dronedarone has been at least as effective and safe as flecainide, despite it was most frequently prescribed in patients with worse baseline risk profile.

Long-term prognostic impact of anticoagulation on patients with atrial fibrillation undergoing hemodialysis. / Impacto pronóstico a largo plazo de la anticoagulación en pacientes en hemodiálisis con fibrilación auricular.

INTRODUCTION AND OBJECTIVES: Evidence for the efficacy and safety of oral anticoagulation with dicumarines in patients with atrial fibrillation (AF) on hemodialysis is controversial. The aim of our study is to evaluate the long-term prognostic implications of anticoagulation with dicumarines in a cohort of patients with non-valvular AF on a hemodialysis program due to end-stage renal disease. METHODS: Retrospective, observational study with consecutive inclusion of 74 patients with AF on hemodialysis. The inclusion period was from January 2005 to October 2016. The primary variables were all-cause mortality, non-scheduled readmissions and bleeding during follow-up. RESULTS: Mean age was 75±10 years; 66.2% were men and 43 patients (58.1%) received acenocoumarol. During a median follow-up of 2.40 years (IQR=0.88-4.15), acenocoumarol showed no survival benefit [HR=0.76, 95% CI (0.35-1.66), p=0.494]. However, anticoagulated patients were at increased risk of recurrent cardiovascular hospitalizations [IRR=3.94, 95% CI (1.06-14.69), p=0.041]. There was a trend towards an increase in repeated hospitalizations of ischemic cause in anticoagulated patients [IRR=5.80, 95% CI (0.86-39.0), p=0.071]. There was a statistical trend towards a higher risk of recurrent total bleeding in patients treated with acenocoumarol [IRR=4.43, 95% CI (0.94-20.81), p=0.059]. CONCLUSIONS: In this study, oral anticoagulation with acenocoumarol in patients with AF on hemodialysis did not increase survival. However, it was associated with an increased risk of hospitalizations of cardiovascular causes and a tendency to an increased risk of total bleeding.

CONCLUSIONS: In our experience, dronedarone has been at least as effective and safe as flecainide, despite it was most frequently prescribed in patients with worse baseline risk profile.

[Red cell distribution width and mortality risk in acute heart failure patients]. / Amplitud de distribución eritrocitaria y riesgo de mortalidad en pacientes con insuficiencia cardiaca aguda.

BACKGROUND AND OBJECTIVE: Red cell distribution width (RDW) is a quantitative measure of the variability in size of erythrocytes, and it is used for the differential diagnosis of anemia. Recent reports have suggested that high RDW could play a role for risk stratification in patients with chronic heart failure. However, the prognostic role of RDW in unselected population with acute heart failure (AHF), after a thoroughly multivariate adjustment, has not been well established. The aim of this study was to establish the association between RDW and long-term mortality in patients admitted for AHF. PATIENTS AND METHOD: We analyzed 1,190 consecutive patients admitted for AHF in our center. RDW measurement was performed on admission. RDW values were stratified into quartiles (Q) and the association of RDW with total mortality was assessed using Cox regression. RESULTS: After a median follow-up of 15 months (interquartile range 3-33 months) 458 (38%) deaths were identified. There was a progressive increase in mortality rates from Q1 to Q4: 1.34, 1.82, 2.56 and 3.53 per 10 patients-year of follow-up (for Q1, Q2, Q3 and Q4 respectively, P for trend <.001). In the multivariate analysis, this association remained independent for patients in Q3 (15-16%) and Q4 (>16%) versus Q1 (≤14%), hazard ratio (HR): 1.66, 95% confidence interval (95% CI) 1.24-2.22, P<.01, HR: 1.80, 95% CI 1.33-2.43, p<.01, respectively, in a model adjusted for established prognostic markers in AHF. CONCLUSION: In patients with AHF, higher RDW values were associated with increased long-term mortality.

[Predictive value of chest pain score for the diagnosis of acute coronary syndromes]. / Valor predictivo de la presentación clínica del dolor torácico en el diagnóstico de los síndromes coronarios agudos.

BACKGROUND AND OBJECTIVE: We analyzed the diagnostic utility of a chest pain score in patients evaluated for chest pain of possible coronary origin. PATIENTS AND METHOD: We studied 1,068 consecutive patients coming to the emergency room with acute chest pain of possible coronary origin without ST-segment elevation, using a chest pain unit protocol. Chest pain was quantified by validated score (0-20 points). The diagnostic value of the chest pain score was analyzed for the diagnosis of acute myocardial infarction (AMI), unstable angina (UA) and acute coronary syndrome (ACS; AMI or UA). RESULTS: The diagnosis of ACS was established in 651 patients (61%), AMI in 439 (41%) and UA in 212 (20%). In the multivariate analysis a chest pain score > or = 10 was an independent predictor of ACS (odds ratio [OR] = 2.9; 95% confidence interval [CI] 2.1-4; p = 0.0001), along with an age older than 70 years (OR = 2.6; 95% CI,1.8-3.7; p = 0.0001), male gender (OR = 2; 95% CI, 1.4-2.8; p = 0.0001); insulin-dependent diabetes (OR = 2.3; 95% CI, 1.2-4.6; p = 0.016); previous myocardial infarction (OR = 1.6; 95% CI, 1.1-2.4; p = 0.022), ST depression (OR = 9.3; 95% CI, 5.2-16.7; p = 0.0001) and T wave inversion (OR = 2.5; 95% CI, 1.4-4.3; p = 0.0001). The chest pain score was associated with the diagnosis of both AMI (OR = 1.4; 95% CI, 1.1-1.9; p < 0.02) and UA (OR = 2.8; 95% CI, 1.8-4.2; p < 0.0001). CONCLUSIONS: The chest pain score allows independent information for the early diagnosis of patients coming to the emergency department with acute chest pain of possible coronary origin.

[Influence of comorbidity on admission management and pharmacological treatment prescribed at discharge in acute myocardial infarction]. / Influencia de la comorbilidad en el tratamiento intrahospitalario y al alta de los pacientes con infarto de miocardio.

BACKGROUND AND OBJECTIVE: The management of cardiac ischemic patients differs depending on their comorbidity. The Charlson Index (ChI) and its adaptations are well established and widely used tools to quantify a patient comorbidity. The aim of this study is to evaluate the influence of comorbidity quantified by the ChI in the treatment administered at admission and in the pharmacological treatment prescribed at discharge in the setting of an acute myocardial infarction with and without ST segment elevation. PATIENTS AND METHOD: We studied a total of 955 patients consecutively admitted in our hospital with the diagnosis of acute myocardial infarction. Comorbidity was obtained at the first day of admission applying the ChI. According to this value patients were classified from minor to major in 2 subgroups (ChI or= 2) and differences in the admission and discharge treatments between both groups were analyzed. RESULTS: Patients admitted with acute myocardial infarction without ST segment elevation and ChI > 2 received less frequently betablockers at discharge, but there were no significant differences in the use of ACE inhibitors, calcium channel blockers or statins. In addition they were submitted less frequently to revascularization procedures or treadmills, and no differences were found in the use of echocardiograms. Patients with ST segment elevation and ChI > 2 were less frequently treated with betablockers or statins at discharge, and were submitted to less treadmills or echocardiograms; furthermore, in these patients, there were no significant differences in the use of ACE inhibitors, calcium channel blockers, thrombolytics or revascularization procedures. CONCLUSIONS: Comorbidity quantified on admission by the ChI is an independent factor that modifies in-hospital and ambulatory management of patients with acute myocardial infarction. There is a lower use of invasive techniques as well as a lower prescription of betablockers at discharge in patients with greater comorbidity.

Hemoptysis as an unusual manifestation of right atrial myxoma.

Atrial myxoma is the most frequent tumor of the heart, though right-side locations and initial clinical manifestation in the form of hemoptysis are infrequent. We describe the case of a young woman with right atrial myxoma diagnosed by transthoracic echocardiography and presenting hemoptysis as the most important manifestation. The symptomatology disappeared after surgical removal of the lesion.
