Acute heart failure - an EFIM guideline critical appraisal and adaptation for internists.

BACKGROUND: Over the past two decades, several studies have been conducted that have tried to answer questions on management of patients with acute heart failure (AHF) in terms of diagnosis and treatment. Updated international clinical practice guidelines (CPGs) have endorsed the findings of these studies. The aim of this document was to adapt recommendations of existing guidelines to help internists make decisions about specific and complex scenarios related to AHF. METHODS: The adaptation procedure was to identify firstly unresolved clinical problems in patients with AHF in accordance with the PICO (Population, Intervention, Comparison and Outcomes) process, then conduct a critical assessment of existing CPGs and choose recommendations that are most applicable to these specific scenarios. RESULTS: Seven PICOs were identified and CPGs were assessed. There is no single test that can help clinicians in discriminating patients with acute dyspnoea, congestion or hypoxaemia. Performing of echocardiography and natriuretic peptide evaluation is recommended, and chest X-ray and lung ultrasound may be considered. Treatment strategies to manage arterial hypotension and low cardiac output include short-term continuous intravenous inotropic support, vasopressors, renal replacement therapy, and temporary mechanical circulatory support. The most updated recommendations on how to treat specific patients with AHF and certain comorbidities and for reducing post-discharge rehospitalization and mortality are provided. Overall, 51 recommendations were endorsed and the rationale for the selection is provided in the main text. CONCLUSION: Through the use of appropriate tailoring process methodology, this document provides a simple and updated guide for internists dealing with AHF patients.

Pulmonary embolism - An EFIM guideline critical appraisal and adaptation for practicing clinicians.

BACKGROUND: Several trials have been conducted in the last decades that challenged the management of patients with acute pulmonary embolism (PE) in terms of diagnosis and treatment. Updated international clinical practice guidelines (CPGs) endorsed the evidence from these trials. The aim of this document was to adapt recommendations from existing CPGs to assist physicians in decision making concerning specific and complex scenarios related to acute PE. METHODS: The flow for the adaptation procedure was first the identification of unsolved clinical issues in patients with acute PE (PICOs), then critically appraise the existing CPGs and choose the recommendations, which are the most applicable to these specific and complex scenarios. RESULTS: Five PICOs were identified and CPGs appraisal was performed. Concerning diagnosis of PE when computed tomographic pulmonary angiography is not available/contraindicated and d-dimer is less specific, perfusion lung scan is the preferred option in the majority of clinical scenarios. For the treatment of PE when relevant clinical conditions like pregnancy or severe renal failure are present heparin is to be used. Poor evidence and low-level recommendations exist on the best bleeding prediction rule in patients treated for PE. The duration of anticoagulation needs to be tailored concerning the presence of predisposing factors for index PE and the consequent risk for recurrence. Finally, recommendations on the opportunity to screen for cancer and thrombophilia patients without recognized thrombosis risk factors for PE are reported. Overall, 35 recommendations were endorsed and the rationale for the selection is reported in the main text. CONCLUSION: By the use of proper methodology for the adaptation process, this document offers a simple and updated guide for practicing clinicians dealing with complex patients.

The new bedside ROCky score to predict the complications in patients with intermediate-risk pulmonary embolism.

OBJECTIVE: Pulmonary embolism (PE) remains one of the leading causes of mortality among cardiovascular diseases. We aimed at investigating risk factors of PE complications in patients with intermediate risk and integrate them into a simple model for its' bedside prediction. METHODS: Among 173 patients with PE, 136 were classified as high or intermediate risk. Patients were retrospectively divided into groups of complicated (n = 44) or uncomplicated (n = 92) course. Study endpoints: obstructive shock, recurrent PE, needs for resuscitation/thrombolysis/hemodynamic support and death during 30 days. RESULTS: Predictors of PE complications were: chronic heart failure, diabetes mellitus (DM), atrial fibrillation, permanent risk factor of venous thromboembolism, syncope, positive heart-type fatty acid binding protein (hFABP), positive troponin I, heart rate (HR) ≥ 110 bpm, systolic blood pressure (SBP) ≤ 100 mmHg, creatinine clearance ≤ 70 ml/min. Multivariate logistic regression analysis was used to model a simple predictive score named ROCky (Risk of Complications): HR ≥ 110 bpm (1.5 points), SBP ≤ 100 mmHg (2.5 points), positive hFABP (2 points) and presence of DM (2.5 points). The AUROC of this model was 0.89 to predict any complication, 0.83 for obstructive shock and 0.92 for death from any cause; the optimal cut-off scores for any complication was ≥2.5 points, ≥3.5 for obstructive shock and ≥4.5 points for death within 30 days. CONCLUSION: hFABP, tachycardia, hypotension and DM were identified as the major independent determinants of complications development in patients with pulmonary embolism and may be used in combination as the bedside simple predictive ROCky score for early risk stratification in intermediate-risk group.

Left Ventricle Non-Compaction Myocardium and Thrombophilia in a Pregnant Woman.

Non-compaction of the ventricular myocardium (NCM) is a genetic cardiomyopathy usually due to mutationof the G4.5 gene located in the Xq28 chromosomal region. This congenital disorder is characterized by pronounced trabeculations and intertrabecular recesses resulting from abnormal embryogenesis between the fifth and eighth fetal weeks. The reported prevalence in the general population is between 0.014% and 1.3%. The classic triad of complications includes heart failure, ventricular arrhythmias and systemic embolic events, although some patients have an asymptomatic form. NCM is commonly diagnosed by echocardiography, but contrast ventriculography, CT and MRI can also be used. Here we present a case of left ventricle NCM, manifested after respiratory infection, in a pregnant patient with congenital thrombophilia and a history of myocardial infarction. LEARNING POINTS: Non-compaction myocardium (NCM) in pregnant women has been associated with a poor prognosis.We should avoid routinely recommending young women with NCM to refuse pregnancy.A decision to continue pregnancy should be made by the patient in discussion with specialists.

Current aspects of correction of neurohumoral system activity in patients after myocardial infarction.

Acute myocardial infarction is still considered as one of the most threatening disorders in internal medicine. Numerous complications of infarction develop due to activation of different neurohumoral systems. The article discusses modern methods of pharmacological correction of neurohumoral system activity in various stages of myocardial infarction. It is emphasized that current guidelines do not always allow to effectively prevent left ventricular remodeling. New drugs used for this aim are discussed.
