Exercise training improves neurovascular control and functional capacity in heart failure patients regardless of age

Background: Exercise training is a non-pharmacological strategy for treatment of heart failure. Exercise training improves functional capacity and quality of life in patients. Moreover, exercise training reduces muscle sympathetic nerve activity (MSNA) and peripheral vasoconstriction. However, most of these studies have been conducted in middle-aged patients. Thus, the effects of exercise training in older patients are much less understood. The present study was undertaken to investigate whether exercise training improves functional capacity, muscular sympathetic activation and muscular blood flow in older heart failure patients, as it does in middle-aged heart failure patients. Design: Fifty-two consecutive outpatients with heart failure from the database of the Unit of Cardiovascular Rehabilitation and Physiology Exercise were divided by age (middle-aged, defined as 45-59 years, and older, defined as 60-75 years) and exercise status (trained and untrained). Methods: MSNA was recorded directly from the peroneal nerve using the microneurography technique. Forearm Blood Flow (FBF) was measured by venous occlusion plethysmography. Functional capacity was evaluated by cardiopulmonary exercise test. Results: Exercise training significantly and similarly increased FBF and peak VO2 in middle-aged and older heart failure patients. In addition, exercise training significantly and similarly reduced MSNA and forearm vascular resistance in these patients. No significant changes were found in untrained patients. Conclusion: Exercise training improves neurovascular control and functional capacity in heart failure patients regardless of age.

Palliative care in the home: perceptions of nurses in the Family Health Strategy

OBJECTIVE: To understand the perception of nurses from the Family Health Strategy in relation to palliative care in the home. METHODS: A descriptive, exploratory study with a qualitative approach conducted with nine nurses from the Family Health Strategy of the municipality of Lavras - MG. Semi-structured interviews were conducted and data were subjected to content analysis. RESULTS: The various dimensions of care in the home context were identified, along with the performance and limitations of nurses in the care of the patient and his family at end of life. The capacity to establish a bond, by the proximity to people who receive their care, is a remarkable point of the action of these nurses with patients and families in end of life situations. CONCLUSION: The nurses consider the patient and his family as the unit of care, they have the opportunity to share solidarity, experiences and learning, not only from a professional standpoint, but above all, from a human one.
