We investigated the prevalence and clinical importance of cardiovascular abnormalities in patients with hyperthyroidism. ⋯ In patients with hyperthyroidism, there is a high prevalence of pulmonary hypertension and atrioventricular valve regurgitation. These abnormalities usually correct after treatment for hyperthyroidism.

Respiratory failure is the leading cause of death among patients admitted with community-acquired pneumonia. We sought to determine the association between arterial carbon dioxide tension (P(a)CO(2)) and in-hospital mortality in patients admitted with pneumonia. ⋯ Among patients admitted with community-acquired pneumonia, in-hospital mortality was greater in those with hypocapnia or hypercapnia. These data suggest that measurement of P(a)CO(2) adds prognostic information to standard prediction rules and should be used for clinical and epidemiologic purposes to risk-stratify in-hospital patients with community-acquired pneumonia.
