Heart failure (HF) is one of the leading causes of adult mortality. Increased risk of death determines need for better understanding of the pathophysiological mechanisms, predictive risk stratification models and applicable methods to improve prognosis. One of the unfavorable prognostic factors may be an inadequate hemodynamic response to orthostatic stress. Orthostatic hypotension (OH) is known to be an independent predictor of many cardiovascular diseases, particularly HF, and death. Singlecenter study of HF population revealed that systolic blood pressure within 3-5 minutes after standing up may be a predictor of long-term unfavorable outcomes. Nevertheless, data about OH in patients with HF are limited and inconsistent due to heterogeneity of populations and different methodology in published studies. In this regard, a population-based study of the orthostatic response in patients with HF (stable and decompensated) is needed. The article describes the rationale and design of a multicenter prospective observational study aimed to assess the clinical and prognostic significance of orthostatic responses in HF patients.
Atrial fibrillation (AF) and cognitive dysfunction - common states with similar risk factors. Recently significant scientific epidemiological data has been received in favor of independence of effect of AF on possibility of development of cognitive dysfunction. In this review we present problems of prevalence, pathogenesis, and diagnostics of various variants of cognitive disorders at the background of AF, as well as methods of their prevention and tactics of anticoagulant therapy in the presence of cognitive disturbances.
Heart failure (HF) is associated with unfavorable outcomes and high health care costs. Determination of the hemodynamic response to orthostasis can be an additional tool in assessing the stability and compensation of HF patients. Active orthostatic test (AOT) with blood pressure monitoring serves as a simple and available screening method. However, a complete characteristic of the hemodynamic response, especially during the first minute of orthostasis, can be obtained only with continuous blood pressure monitoring. The presented case series demonstrate the types of hemodynamic response in patients with heart failure with reduced ejection fraction in AOT with continuous blood pressure monitoring, available data on the mechanisms of its development, clinical and prognostic role, and also presents the advantages and limitations of AOT.
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.
