Heart failure is one of the most important and challenging public health problems of the 21 st century and is associated with hard outcomes, such as death and hospitalization. New treatments for heart failure, despite the decrease in mortality, have not contributed to the decrease in hospitalization rates. Patients admitted with heart failure have a high event rate (> 50%) with a mortality rate between 10 and 15% and a rehospitalization rate within 6 months after discharge of 30 to 40%. Three major causes seem to directly affect the rehospitalization of patients with heart failure: comorbidities, congestion and target-organ lesion. The transition from inpatient to outpatient is a period of vulnerability, due to the progressive nature complexity of heart failure, with an impact on prognosis and which can extend for up to 6 months after hospital discharge. The physician has an important role in the actions that can minimize the risk of hospitalization for heart failure and the multidisciplinary approach, associated with the implementation of good practices supported by scientific evidence, can reduce the risk of hospitalization. The use of routines that have been proven to reduce hospitalization should be used in Brazilian hospitals. The objective of this review was to discuss the main causes of hospitalization, their impact on heart failure evolution and strategies that can be used to reduce it.
Heart failure with preserved ejection fraction (HFpEF) is now an emerging cardiovascular epidemic, being identified as the main phenotype observed in clinical practice. It is more associated with female gender, advanced age and comorbidities such as hypertension, diabetes, obesity and chronic kidney disease. Amyloidosis is a clinical disorder characterized by the deposition of aggregates of insoluble fibrils originating from proteins that exhibit anomalous folding. Recently, pictures of senile amyloidosis have been described in patients with HFpEF, demonstrating the need for clinical cardiologists to investigate this etiology in suspect cases. The clinical suspicion of amyloidosis should be increased in cases of HFPS where the cardio imaging methods are compatible with infiltrative cardiomyopathy. Advances in cardio imaging methods combined with the possibility of performing genetic tests and identification of the type of amyloid material allow the diagnosis to be made. The management of the diagnosed patients can be done in partnership with centers specialized in the study of amyloidosis, which, together with the new technologies, investigate the possibility of organ or bone marrow transplantation and also the involvement of patients in clinical studies that evaluate the action of the new emerging drugs.
Vitamin D is considered a steroid hormone with a broad spectrum of action in the human body. Its action arises from the binding of its active metabolite (1α,25-dihydroxyvitamin D) to its receptor (VDR), which is present throughout the body, including vascular smooth muscle cells and cardiomyocytes. Initially, vitamin D deficiency was related only to changes in the musculoskeletal system, but in recent years, researchers have demonstrated its relationship with several pathologies related to other systems, such as cardiovascular diseases. The objective of this study is to review vitamin D's pathophysiology, describe its relationship with cardiovascular diseases based on the most recent publications, and highlight the results of vitamin supplementation in the prevention of such pathologies.

The image of the hospital representing the modern medicine and its diagnostic and therapeutic advances becomes more evident in the face of an aging population and patients with multiple comorbidities requiring highly complex care. However, recent studies have shown a growing number of hospital readmissions within 30 days after discharge. The post-hospital syndrome is a new clinical entity associated with multiple vulnerabilities that contribute to hospital readmissions. During hospitalization, the patient is exposed to different stressors of physical, environmental, and psychosocial natures that trigger pathophysiological and multisystemic responses and increase the risk of complications after hospital discharge. Patients with a cardiac disease have high rates of readmission within 30 days. Therefore, it is important for cardiologists to recognize the post-hospital syndrome since it may impact their daily practice. This review aims at discussing the current scientific evidence regarding predictors and stressors involved in the post-hospital syndrome and the measures that are currently being taken to minimize their effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
