Loop diuretic discontinuation in chronic heart failure patients: A retrospective study.

Introduction And Objectives: The use of loop diuretics is central in managing congestion in heart failure (HF), but their impact on prognosis remains unclear. In euvolemic patients, dose reduction is recommended, but there is no recommendation on their discontinuation. This study aims to assess the impact of loop diuretic discontinuation on the prognosis of outpatients with HF with reduced ejection fraction.

Iatrogenic ventricular fibrillation in Wolff-Parkinson-White syndrome.

Wolff-Parkinson-White (WPW) syndrome is the most common manifestation of ventricular pre-excitation syndrome and is mostly found in individuals with no structural heart disease. Although the risk of malignant arrhythmias is low, sudden cardiac death (SCD) as the first clinical manifestation of WPW syndrome is well documented, and atrial fibrillation (AF) with a rapid ventricular response is the main mechanism involved. Unfortunately, the signs of pre-excitation and arrhythmias are sometimes under-diagnosed and under-treated.

Hyperkalemia as a limiting factor of neurohormonal blockade/modulation in everyday clinical practice.

Introduction And Objectives: Neurohormonal blockade (NB)/modulation is the combination of two renin-angiotensin-aldosterone system inhibitors (RAASi) with a beta blocker. It is the core therapy for heart failure with reduced ejection fraction (HFrEF). While improving long term prognosis, it also induces hyperkalemia (serum K >5.

Sacubitril/valsartan in everyday clinical practice: an observational study based on the experience of a heart failure clinic.

Background: Heart failure (HF) is a growing public health problem. Sacubitril/valsartan is now recommended to be used in persistently symptomatic patients with left ventricular ejection fraction (LVEF) <40%, replacing angiotensin-converting enzyme inhibitors (ACEis)/angiotensin receptor blockers (ARBs). In the present study, we aimed to characterise the challenges of sacubitril/valsartan use in everyday clinical practice.

Does the type of seizure influence heart rate variability changes?

Objective: Heart rate variability (HRV), an index of the autonomic cardiac activity, is decreased in patients with epilepsy, and a low HRV is associated with a higher risk of sudden death. Generalized tonic-clonic seizures are one of the most consistent risk factors for SUDEP, but the influence (and relative risk) of each type of seizure on cardiac function is still unknown. Our objective was to assess the impact of the type of seizure (focal to bilateral tonic-clonic seizure - FBTCS - versus non-FBTCS) on periictal HRV, in a group of patients with refractory epilepsy and both types of seizures.

Heart rate variability in patients with refractory epilepsy: The influence of generalized convulsive seizures.

Objective: Patients with epilepsy, mainly drug-resistant, have reduced heart rate variability (HRV), linked to an increased risk of sudden death in various other diseases. In this context, it could play a role in SUDEP. Generalized convulsive seizures (GCS) are one of the most consensual risk factors for SUDEP.

Temporal trends of lipid control in very high cardiovascular risk patients.

Introduction: Since 2011, the European guidelines have included a specific low-density lipoprotein cholesterol (LDL-C) target, <70 mg/dl, for very high cardiovascular risk (CVR) patients. However, registries have shown unsatisfactory results in obtaining this level of adequate lipid control.

Objectives: To assess temporal trends in the use of lipid-lowering therapy (LLT) and attainment of adequate control in very high CVR patients since 2011.

Genetic variants identified by target next-generation sequencing in heart transplant patients with dilated cardiomyopathy.

Introduction And Objectives: Dilated cardiomyopathy (DCM) is a myocardial disease that can progress to a terminal stage, requiring heart transplantation. In this work we aim to contribute to knowledge of genetic variants in adult patients undergoing heart transplantation due to end-stage DCM, reporting the results obtained in our single-center tertiary hospital series using target next-generation sequencing (NGS).

Methods And Results: Genetic variants were screened in 15 genes, preselected based on variants previously identified in DCM patients.

Genetic Variants Are Not Rare in ICD Candidates with Dilated Cardiomyopathy: Time for Next-Generation Sequencing?

Background: Sudden cardiac death (SCD) risk stratification in dilated cardiomyopathy (DCM) has been based on left ventricular ejection fraction (LVEF), even though SCD may occur with LVEF > 35%. Family history of unexplained SCD, especially in the young, raises concern about potential inheritable risk factors. It remains largely unknown how genetic tests can be integrated into clinical practice, particularly in the selection of implantable cardioverter defibrillator (ICD) candidates.

Cardiac papillary fibroelastoma: Report of a surgical series.

Introduction: Papillary fibroelastoma (PFE) is a rare primary benign tumor of cardiac origin that predominantly affects the cardiac valves. Although most patients are asymptomatic, serious complications may result given their propensity for embolization. Advances in imaging technology have enabled earlier detection and more accurate characterization of these tumors.

Cardiac pauses during sleep in a patient with sleep obstructive apnea and atrial fibrillation.

Cardiac rhythm disturbances are common in sleep apnea patients. The authors report on a 74-year-old female patient with atrial fibrillation, with a background history of arterial hypertension, obesity, and obstructive sleep apnea. Holter monitoring was performed, on 5 different occasions.

The role of biomarkers in dilated cardiomyopathy: Assessment of clinical severity and reverse remodeling.

Introduction: Biomarkers in dilated cardiomyopathy (DCM) reflect various pathobiological processes, including neurohormonal activation, oxidative stress, matrix remodeling, myocyte injury and myocyte stretch. We assessed the role of biomarkers in clinical and echocardiographic parameters and in left ventricular (LV) reverse remodeling (LVRR).

Methods: In this prospective study of 50 DCM patients (28 men, aged 59±10 years) with LV ejection fraction (LVEF) <40%, LVRR was defined as an increase of >10 U in LVEF after optimal medical therapy.

Left ventricular reverse remodeling in dilated cardiomyopathy- maintained subclinical myocardial systolic and diastolic dysfunction.

In idiopathic dilated cardiomyopathy (DCM), myocardial deformational parameters and their relationships remain incompletely characterized. We measured those parameters in patients with DCM, during left ventricular reverse remodeling (LVRR). Prospective study of 50 DCM patients (in sinus rhythm), with left ventricular ejection fraction (EF) <40%.

Cardiotoxicity in anthracycline therapy: Prevention strategies.

The increasing use of anthracyclines, together with the longer survival of cancer patients, means the toxic effects of these drugs need to be monitored. In order to detect, prevent or mitigate anthracycline-induced cardiomyopathy, it is essential that all patients undergo a rigorous initial cardiovascular assessment, followed by close monitoring. Several clinical trials have shown the cardioprotective effect of non-pharmacological measures such as exercise, healthy lifestyles, control of risk factors and treatment of comorbidities; a cardioprotective effect has also been observed with pharmacological measures such as beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists, statins, dexrazoxane and liposomal formulations.

Prevalence, predictors and prognosis of ventricular reverse remodeling in idiopathic dilated cardiomyopathy.

Introduction: Cardiac remodeling is manifested as changes in size, shape and function of the heart. We studied the prevalence, prognosis and predictors of left ventricular reverse remodeling (LVRR) in idiopathic dilated cardiomyopathy (IDCM) after optimized medical therapy.

Methods: A total of 113 IDCM patients were followed for 7.

Massive hemoptysis as an unusual complication of right heart catheterization: Successful treatment with percutaneous stent.

Electrocardiographic evaluation in athletes: 'Normal' changes in the athlete's heart and benefits and disadvantages of screening.

Young athletes are considered the healthiest group in society. Although rare, there are still reports of sudden death or cardiac arrest on the playing fields. Clinical evaluation is of paramount importance for the identification of possible pathological states that confer increased risk of these events.

Severe aortic stenosis: forgotten associations.

The authors present the case of a 68-year-old man with predominantly right heart failure in the context of severe aortic stenosis associated with pulmonary hypertension. Anemia was diagnosed which, after endoscopic study, was considered to be secondary to angiodysplasia and a diagnosis of Heyde syndrome was made. After valve replacement surgery the patient's heart failure improved and hemoglobin levels stabilized.

Post-cardiac injury syndrome following transvenous pacing: case report.

Post-cardiac injury syndrome (PCIS) is an inflammatory process involving the pericardium secondary to cardiac injury. It can develop after cardiac trauma, cardiac surgery, myocardial infarction, and, rarely, after certain intravascular procedures. We report a rare case of an iatrogenic cardiac rupture followed by PCIS with delayed inflammatory pericardial effusion after pacemaker implantation.
