Review Case Reports
Left spontaneous pneumothorax presenting with ST-segment elevations: a case report and review of the literature.
Common electrocardiogram (ECG) changes associated with left-sided pneumothorax include right axis deviation, reduced R-wave amplitude in precordial leads, QRS alterations (amplitude changes), and T-wave inversions. Few reports exist of ST-segment elevations or changes suggestive of acute myocardial infarction (AMI), and these involve older patients with tension pneumothorax and previous coronary heart disease. ⋯ All changes resolved after decompression of the pneumothorax. On the basis of the patient's presenting symptoms, response to therapy, and our review of the literature, we propose a number of possible mechanisms explaining his electrocardiographic findings.

To examine the evidential basis underpinning the monitoring of skin temperature and core-peripheral temperature gradient as elements of hemodynamic assessment in critically ill and adult cardiac surgical patients. ⋯ Skin temperature and core-peripheral temperature gradient should not be considered in isolation from other hemodynamic parameters when assessing cardiac status until they are validated by further large-scale prospective studies.

Chronic obstructive pulmonary disease (COPD) affects millions worldwide. Despite advances in the treatments of other chronic diseases, little progress in decreasing COPD morbidity and mortality has been made. The death rate associated with COPD has doubled in 30 years. The presence of psychiatric comorbidities, such as anxiety and depression, has been linked to increased mortality, decreased functional status, and decreased quality of life. ⋯ Although the prevalence of anxiety and depression among patients with COPD is significantly higher than the general population, there are serious barriers to the recognition and treatment of these comorbid conditions. Routine assessment and screening for anxiety and depression in all patients diagnosed with COPD should be considered.

Despite the increased mortality and morbidity in patients with acute decompensated heart failure (ADHF), its management has been based primarily on anecdotal experiences and physiologic assumptions rather than on prospective randomized controlled trials. The data on diuretics have been conflicting. ⋯ Good evidence that supports the safety and efficacy of the different medications that are routinely used in ADHF is lacking. Unless properly designed prospective clinical trials are done to evaluate the safety of the various ADHF regimens, clinicians might continue to be misguided by the beneficial short-term effects at the expense of long-term mortality and morbidity.

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy, left ventricular apical ballooning syndrome, and broken heart syndrome, is a clinical entity first described in the early 1990s in Japan and now receiving increased attention in the United States. The clinical features include an onset of chest pain mimicking that of an acute myocardial infarction, electrocardiogram changes similar to those of an acute myocardial infarction, normal coronary arteries on cardiac catheterization, and a signature appearance on echocardiogram. Takotsubo cardiomyopathy results in a significantly decreased ejection fraction that, as long as the patient receives appropriate hemodynamic support, typically undergoes spontaneous reversal. This article describes the history, clinical presentation, and management strategies for Takotsubo cardiomyopathy and provides a case study.
