Diastolic Dysfunction Is a Contributing Factor to Exercise Intolerance in COPD.

Right ventricular (RV) systolic failure is rare in patients with COPD, but they often develop RV diastolic dysfunction. Left ventricular (LV) diastolic dysfunction is also common in this population. Nevertheless, data are scarce regarding the effect of diastolic dysfunction on the functional capacity in patients with COPD.

PET-CT imaging and reality.

The spectrum of human diseases caused by members of the Aspergillus genus is extensive. It ranges from allergic reactions to colonization of preexisting pulmonary cavities to invasion and destruction of lung parenchyma with pyemic spread to brain, skin, and other organs, causing rapid death. The immune status of the host is a crucial factor in determining the phenotype and severity of the disease.
