Basic action protocol for the outpatient management of chronic heart failure of the Spanish Society of Internal Medicine.

Chronic heart failure (CHF) represents a challenge for the healthy system due to its high prevalence, high burden of morbidity and mortality, and high consumption of health resources. To address this problem, it is necessary to develop efficient management strategies that include both hospital care and outpatient care. The primary objective is to stabilize the patient and prevent decompensation, with the consequent improvement in quality of life, reduction in hospital admissions and emergency department care, and, consequently, reduction in healthcare costs. In this context, the heart failure and atrial fibrilation working group of the Spanish Society of Internal Medicine has developed a protocol for the management of outpatient CHF, that addresses, from the perspective of Internal medicine, all the problems suffered by the patient with CHF. This protocol aims to optimize pharmacological treatment, control cardiovascular risk factors and various comorbidities, educate the patient and their environment about the disease, promote adherence to treatment and stablish follow-up adapted to their condition.

Cardiac amyloidosis worsens prognosis in patients with heart failure: findings from the PREVAMIC study.

BACKGROUND AND OBJECTIVES: Cardiac amyloidosis (CA) is a common pathology in elderly patients that usually presents as heart failure (HF). However, it is not clear whether CA associated with HF has a worse prognosis compared with HF due to other etiologies. MATERIAL AND METHODS: Prospective, observational cohort study that recruited patients ≥65 years of age with HF in 30 Spanish centers. The cohort was divided according to whether the patients had AC or not. Patients were followed for 1 year. RESULTS: A total of 484 patients were included in the analysis. The population was elderly (median 86 years) and 49% were women CA was present in 23.8 % of the included patients. In the CA group, there was a lower prevalence of diabetes mellitus and valvular disease. At one year of follow-up, mortality was significantly more frequent in patients with CA compared to those without (33.0 vs.14.9%, p < 0.001). However, there were no differences between both groups in visits to the emergency room or readmissions. In the multivariate analysis, the variables that were shown to predict all-cause mortality at one year of follow-up were chronic kidney disease (HR 1.75 (1.01-3.05) p 0.045), NT-proBNP levels (HR 2.51 (1.46-4.30) p < 0.001), confusion (HR 2.05 (1.01-4.17), p 0.048), and the presence of CA (HR 1.77 (1.11-2.84), p 0.017). CONCLUSION: The presence of CA in elderly patients with HF is related to a worse prognosis at one year of follow-up. Early diagnosis of the pathology and multidisciplinary management can help improve patient outcomes.

Sex differences in clinical characteristics and outcomes in the CLOROTIC (combining loop with thiazide diuretics for decompensated heart failure) trial.

AIMS: The addition of hydrochlorothiazide (HCTZ) to furosemide improved the diuretic response in patients with acute heart failure (AHF) in the CLOROTIC trial. Our aim was to evaluate if there were differences in clinical characteristics and outcomes according to sex. METHODS: This is a post-hoc analysis of the CLOROTIC trial, including 230 patients with AHF randomized to receive HCTZ or placebo in addition to an intravenous furosemide regimen. The primary and secondary outcomes included changes in weight and patient-reported dyspnoea 72 and 96 h after randomization, metrics of diuretic response and mortality/rehospitalizations at 30 and 90 days. The influence of sex on primary, secondary and safety outcomes was evaluated. RESULTS: One hundred and eleven (48%) women were included in the study. Women were older and had higher values of left ventricular ejection fraction. Men had more ischemic cardiomyopathy and chronic obstructive pulmonary disease and higher values of natriuretic peptides. The addition of HCTZ to furosemide was associated to a greatest weight loss at 72/96 h, better metrics of diuretic response and higher 24-h diuresis compared to placebo without significant differences according to sex (all p-values for interaction were not significant). Worsening renal function occurred more frequently in women (OR [95%CI]: 8.68 [3.41-24.63]) than men (OR [95%CI]: 2.5 [0.99-4.87]), p = 0.027. There were no differences in mortality or rehospitalizations at 30/90 days. CONCLUSION: Adding HCTZ to intravenous furosemide is an effective strategy to improve diuretic response in AHF with no difference according to sex, but worsening renal function was more frequent in women.

Prognostic utility of pulse pressure in patients with heart failure with preserved ejection fraction: The RICA Registry.

BACKGROUND AND AIMS: The prognostic role of pulse pressure (PP) in heart failure (HF) patients with preserved left ventricular ejection fraction (LVEF) is not well understood. Our aim was to evaluate it in acute and stable HF. MATERIAL AND METHODS: This work is a retrospective observational study of patients included in the RICA registry between 2008 and 2021. Blood pressure was collected on admission (decompensation) and 3 months later on an outpatient basis (stability). Patients were categorized according to whether the PP was greater or less than 50mmHg. All-cause mortality was assessed at 1year after admission. RESULTS: A total of 2291 patients were included, with mean age 80.1±7.7 years. 62.9% were women and 16.7% had a history of coronary heart disease. In the acute phase, there was no difference in mortality according to PP values, but in the stable phase PP<50mmHg was independently associated with all-cause mortality at 1-year follow-up (HR 1.57, 95% CI 1.21-2.05, p=0.001), after adjusting for age, sex, New York Heart Association functional class, previous HF, chronic kidney disease, valvular heart disease, cerebrovascular disease, score on the Barthel and Pfeiffer scales, hemoglobin and sodium levels. CONCLUSIONS: Low stable-phase PP was associated with increased all-cause mortality in HF patients with preserved LVEF. However, PP was not useful as a prognostic marker of mortality in acute HF. Further studies are needed to assess the relationship of this variable with mortality in HF patients.

The short-term prognostic value of C-reactive protein in elderly patients with acute heart failure. / Valor pronóstico a corto plazo de la proteína C reactiva en ancianos con insuficiencia cardíaca aguda.

INTRODUCTION AND OBJECTIVES: Plasma c-reactive protein (crp) has been tested as a prognostic marker in acute heart failure (ahf). Whether its measurement really provides significant prognostic information when applied to elderly patients with ahf episodes remains unclear. METHODS: We measured the plasma crp values of patients admitted because of any type of ahf to internal medicine services. We evaluated the association of these values with the patients' baseline clinical characteristics and their 3-month posdischarge all-cause mortality or readmission rates. For comparison purposes, we divided the sample in tertiles of low, medium and high crp values (<2,24mg/l, 2,25-11,8mg/l and>11,8mg/l). RESULTS: We included 1443 patients with a median age of 80 years (interquartile range 73-85); 680 (47%) were men, with a moderate comorbid burden. 60.1% had preserved left ventricular ejection fraction (> 50%). Multivariate analysis confirmed an independent association between higher crp values and the presence of respiratory infection, lower systolic blood pressure and deteriorated renal function upon admission. Three months after the index admission, a total of 142 patients (9.8%) had died, and 268 (18.6%) had either been readmitted or died. admission crp values did not correlate with 3-month all-cause mortality (P=0.79), 3-month all-cause readmission (P=0.96) or the combination of both events (P=0.96). However, higher crp values were associated with a longer length of stay (P<0.001). CONCLUSION: Our study does not confirm an association between admission plasma crp values in elderly ahf patients and subsequent higher 3-month mortality or readmission risks.

Impact of prealbumin on mortality and hospital readmission in patients with acute heart failure.

BACKGROUND: Prealbumin is a maker of nutritional status and inflammation of potential prognostic value in acute heart failure (HF). The aim of this study is to evaluate if low prealbumin levels on admission predict mortality and readmissions in patients with acute HF. METHOD: We conducted a prospective observational cohort study including 442 patients hospitalized for acute HF. Patients were classified in two groups according to prealbumin levels: "normal" prealbumin (>15mg) and "low" prealbumin (≤15mg/dL). End-points were mortality and readmissions (all-cause and HF-related) and the combined end-point of mortality/readmission at 180days. RESULTS: Out of 442 patients, 159 (36%) had low and 283 (64%) had normal prealbumin levels Mean age was 79.6 (73.9-84.2, p=0,405) years and 183 (41%, p=0,482) were males. After a median 180days of follow-up, 108 (24%, p=0,021) patients died and 170 (38%, p=0,067) were readmitted. Mortality was higher in the low prealbumin group. The combined end-point was more frequent in the low prealbumin group (57% vs. 50%, p=0.199). In the multivariate analysis the following variables were associated with mortality or readmission: older age, exacerbated chronic HF, higher comorbidity, low systolic blood pressure and hemoglobin values and higher pro brain natriuretic peptide levels. CONCLUSIONS: Low prealbumin is common (36%) in patients with acute heart failure and it is associated with a higher short-term mortality.
