Abstract The left atrium is an anatomical structure relevant to the maintenance of the physiological hemodynamics of the cardiovascular system. Atrial cardiomyopathy (aCMP), defined as any change in the structure, architecture, contractility or electrophysiology of the atria, is associated with adverse clinical implications, and responsible for atrial fibrillation and stroke. Heart failure with preserved ejection fraction (HFpEF) with a predominance of atrial fibrillation (AF) is a unique clinical phenotype, characterized by mechanical dysfunction of the left atrium, congestive symptoms and […]

Introduction Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome that has a negative impact on quality of life and life expectancy of patients, with high hospitalization and mortality rates. HFpEF is a highly prevalent disease, probably due to the increase in the prevalence of common risk factors, such as advanced age, female sex, arterial hypertension, diabetes, renal failure and obesity., It is estimated that nearly half of heart failure patients have preserved ejection fraction, defined as […]

Heart failure with preserved ejection fraction (HFpEF) is a frequent clinical syndrome, and it has accounted for 40% to 50% of heart failure hospitalizations in several reports published in the literature., It is a distinctly heterogeneous syndrome, and, with this diversity of scenarios, patients with a restrictive cardiomyopathy phenotype have been increasingly identified, especially elderly patients with cardiac amyloidosis. Restrictive cardiomyopathies are diseases of the heart muscle that can arise due to various etiologies, including genetic abnormalities, infiltrative diseases, and […]
