Background: Postoperative atrial fibrillation (POAF) is the most common arrhythmia following cardiac surgery (CS). It may occur between the 1st and the 4th postoperative day as acute POAF or between the 5th and the 30th as subacute (sPOAF). sPOAF is associated with higher thromboembolic risk, which consistently increase patients' morbidity. Neutrophil‐to‐lymphocyte ratio (NLR) is a low‐cost inflammatory index proposed as possible POAF predictor. Identification of patients' risk categories might lead to improved postoperative outcomes. Methods: The aim was to assess the incidence of sPOAF and to identify possible predictors in patients performing cardiovascular rehabilitation (CR) after CS. A single‐center cohort study was performed on 737 post‐surgical patients admitted to CR on sinus rhythm. Continuous monitoring with 12‐lead ECG telemetry was performed. We evaluated the predictive role of anamnestic, clinical, and laboratory data, including baseline NLR. Results: Subacute POAF was documented in 170 cases (23.1%). At the multivariate analysis, age (OR 1.03; p =.001), mitral valve surgery (OR 1.77; p =.012), acute POAF (OR 2.97; p <.001), and NLR at baseline (OR 1.13; p =.042) were found to be independent predictive factors of sPOAF following heart surgery. Conclusions: sPOAF is common after CS. Age, mitral valve procedures, acute POAF, and preoperative NLR were proved to increase sPOAF occurrence in CR. NLR is an affordable and reliable parameter which might be used to qualify the risk of arrhythmias at CR admission. Identification of new predictors of postoperative atrial fibrillation may allow to improve patients' prognosis. [ABSTRACT FROM AUTHOR]

Diaphragm dysfunction is a common complication following cardiac surgery. Its clinical impact is variable, ranging from the absence of symptoms to the acute respiratory failure. Post‐operative diaphragm dysfunction may negatively affect patients' prognosis delaying the weaning from the mechanical ventilation (MV), extending the time of hospitalization and increasing mortality. Ultrasonography is a valid tool to evaluate diaphragmatic impairment in different settings, like the Intensive Care Unit, to predict successful weaning from the MV, and the Cardiovascular Rehabilitation Unit, to stratify patients in terms of risk of functional recovery failure. The aim of this review is to describe the pathophysiology of post‐cardiac surgery diaphragm dysfunction, the techniques used for its diagnosis and the potential applications of diaphragm ultrasound.

The goal of this review was to present a complete picture of PPS and pericardial complications after cardiac surgery, highlighting available evidence and gaps in knowledge. METHODS A literature review was performed that included relevant prospective and retrospective studies on the subject. RESULTS PPS occurs frequently and is associated with elevated morbidity and significantly increased hospital stays and costs. Nevertheless, PPS is often underestimated in clinical practice, and knowledge of its pathogenesis and epidemiology is limited. Several anti-inflammatory drugs have been investigated for treatment but with conflicting evidence. Colchicine demonstrated encouraging results for prevention. CONCLUSIONS Wider adoption of standardized diagnostic criteria to correctly define PPS and start early treatment is needed. Larger studies are necessary to better identify high-risk patients who might benefit from preventive strategies. [ABSTRACT FROM AUTHOR]

Objectives: Coronavirus disease 2019 (COVID‐19) is a viral illness caused by severe acute respiratory syndrome coronavirus 2. With the increasing number of improved and discharged patients with COVID‐19, the definition of an adequate follow‐up strategy is needed. The purpose of this study was to assess whether lung ultrasound (LUS) is an effective indicator of subclinical residual lung damage in patients with COVID‐19 who meet discharge criteria. Methods: We prospectively enrolled 70 consecutive patients with COVID‐19 who had a prolonged hospitalization with inpatient rehabilitation between April 6 and May 22, 2020. All of the patients underwent an LUS evaluation at discharge. Data of patients with more severe disease during the acute phase (ie, required ventilatory support) were compared to those of patients with milder disease. Results: Among the 70 patients with COVID‐19 (22 women and 48 men; mean age ± SD, 68 ± 13 years), the LUS score before discharge was still frankly pathologic and higher in patients who had more severe disease during the acute phase compared to patients with milder disease (median [interquartile range], 8.0 [5.5–13.5] versus 2.0 [1.0–7.0]; P <.001), even when both categories met internationally defined discharge criteria. Conclusions: Lung ultrasound can identify the persistence of subclinical residual lung damage in patients with severe COVID‐19 even if they meet discharge criteria. Considering the low cost, easy application, and lack of radiation exposure, LUS seems the ideal tool to be adopted in outpatient and primary care settings for the follow‐up of patients with COVID‐19.
