Introduction: We conducted a study to determine the prevalence of structural heart disease in patients with CF, the characteristics of a cardiomyopathy not previously described in this population, and its possible relationship with nutritional deficiencies in CF.
Methods: We studied 3 CMP CF patients referred for heart-lung transplantation and a prospective series of 120 adult CF patients. All patients underwent a clinical examination, blood tests including levels of vitamins and trace elements, and echocardiography with evaluation of myocardial strain.
A 21-year-old woman with a history of atopy, peripheral eosinophilia, Wolf-Parkinson-White syndrome, and 5 episodes of myocarditis was diagnosed with eosinophilic myocarditis. Despite adequate immunosuppressive treatment and resolution of the myocarditis episode, the patient developed dilated cardiomyopathy and presented with worsening of her functional class. Finally, genetic testing unveiled an additional diagnosis: Danon disease.

Some authors propose that the way to reduce VILI is to find the threshold of driving pressure below which VILI is minimized. In this study, we propose a method to titrate the driving pressure to pulmonary elastance in an acute respiratory distress syndrome model using Young's modulus and its consequences on ventilatory-induced lung injury.
