Persistent COVID-19 symptoms 1 year after hospital discharge: A prospective multicenter study.

Objective: To determine the health status and exercise capacity of COVID-19 survivors one year after hospital discharge.

Methods: This multicenter prospective study included COVID-19 survivors 12 months after hospital discharge. Participants were randomly selected from a large cohort of COVID-19 patients who had been hospitalized until 15th April 2020.

Long-term impact of COVID-19 associated acute respiratory distress syndrome.

Objectives: To determine the health status, exercise capacity, and health related quality of life (HRQoL) of COVID-19 associated acute respiratory distress syndrome (ARDS) survivors, 8 months after diagnosis.

Methods: All eligible patients were interviewed and underwent a physical examination, chest X-ray, and 6 min walk test (6MWT). Scales to evaluate post-traumatic stress disorder, depression, anxiety, and HRQoL were applied.

Spironolactone in patients with heart failure and preserved ejection fraction.

Objectives: Aldosterone inhibitors have been shown to be beneficial for patients with systolic heart failure. However, the evidence from patients with heart failure and preserved ejection fraction (HFPEF) is limited. We evaluated the role of spironolactone in the prognosis of a cohort of patients with HFPEF.

Hyponatremia as predictor of worse outcome in real world patients admitted with acute heart failure.

Background: Our aim was to determine if hyponatremia, defined as serum sodium level < 135 mmol/L, is a predictor of worse outcome in a cohort of real-world patients with heartfailure (HF).

Methods: We used data of the National registry of HF (RICA) from Spain, an ongoing multicenter, prospective cohort study. The patients were assigned to two groups regarding sodium levels.
