Salt and fluid restriction is effective in patients with chronic heart failure.

AIMS: European and American guidelines have recommended salt and fluid restriction for patients with chronic heart failure (CHF) despite scarce scientific evidence. Therefore, we investigated the effects of salt and fluid restriction in patients with CHF. METHODS AND RESULTS: Ninety-seven stable patients in NYHA class II-IV, on optimal medication, with previous signs of fluid retention, [...]

Paradoxical heart failure precipitated by profound dehydration: intraventricular dynamic obstruction and significant mitral regurgitation in a volume-depleted heart.

Occurrence of dynamic left ventricular outflow tract (LVOT) obstruction is not infrequent in critically ill patients, and it is associated with potential danger. Here, we report a case of transient heart failure with hemodynamic deterioration paradoxically induced by extreme dehydration. This article describes clinical features of the patient and echocardiographic findings of dynamic LVOT obstruction [...]

The Influence of Rehydration Mode Following Exercise Dehydration on Cardiovascular Function

Our purpose was to compare common modes of rehydration (REHY) on cardiovascular and fluid regulation recovery following exercise dehydration (EXDE). Twelve non-heat-acclimatized trained subjects (23±4y, 81.3±3.7kg, 180±6cm, 56.9±4.4mLminkg VO2max, 7.8±3.0 % body fat) completed 20-h fluid restriction and 2-h EXDE to -4% body mass, then were rehydrated to -2% body mass in a randomized, cross-over [...]

Dysphagia, nutrition, and hydration in ischemic stroke patients at admission and discharge from acute care.

Dysphagia may predispose stroke patients toward undernutrition and hydration. These comorbidities increase patient risks for reduced functional outcome and short-term mortality. Despite this impact, available information on relationships among dysphagia, nutrition, and hydration status in acute stroke is limited and conflicted. This study evaluated nutrition and hydration status in ischemic stroke patients with versus without [...]

Early and personalized ambulatory follow-up to tailor furosemide and fluid intake according to congestion in post-discharge heart failure.

Congestive heart failure (CHF) worsening is a worldwide cause of rehospitalization and mortality, specially during the early period after hospitalization. Fluid accumulation plays a key role in the pathophysiology of both acute heart decompensation and disease progression. The effective use of drugs to maintain restored clinical stabilization in recently discharged patients is a difficult task, [...]

Thirst in heart failure: a systematic literature review.

AIMS: Although patients with heart failure (HF) may suffer from severe thirst, this has received little attention in scientific studies. A systematic literature review was conducted to identify and analyse data on thirst in HF. METHODS AND RESULTS: Pubmed, Cochrane, Cinahl, and Medline databases were searched for original studies on patients with HF with thirst [...]

Circulatory regulation during exercise in different ambient temperatures.

Three relatively fit subjects performed duplicate 20- to 25-min cycle ergometer exercise bouts at moderate and heavy intensities (40% and 70% Vo2 max) in ambient temperatures of 20, 26, and 36 degrees C. They approached a steady state in internal body temperature (Tes) in all but the heavy exercise in the heat, where Tes rose consistently, averaging 38.84 degrees C at the termination of exercise.

Human circulatory and thermoregulatory adaptations with heat acclimation andexercise in a hot, dry environment.

1. Heat acclimation was induced in eight subjects by asking them to exercise until exhaustion at 60% of maximum oxygen consumption rate (VO2) for 9-12 consecutive days at an ambient temperature of 40 degrees C, with 10% relative humidity (RH). Five control subjects exercised similarly in a cool environment, 20 degrees C, for 90 min for 9-12 days; of these, three [...]
