Comparative Study
High-sensitivity cardiac troponin T is more helpful in detecting peri-operative myocardial injury and apoptosis during coronary artery bypass graft surgery.
To determine whether there is a correlation between cardiac markers and peri-operative myocardial injury (PMI) and apoptosis in coronary artery bypass graft (CABG) surgery and to compare the efficacy of cardiac markers to detect PMI. ⋯ Although both cTnI and hs-cTnT may be specific and efficacious markers of myocardial apoptosis and injury occurring during CABG with CPB, hs-cTnT may be a more useful marker than cTnI to detect peri-operative myocardial apoptosis and injury.

Review Case Reports
Dyspnoea and chest pain as the presenting symptoms of pneumomediastinum: two cases and a review of the literature.
Pneumomediastinum is the presence of air in the mediastinum. It may occur as spontaneous, traumatic, or iatrogenic pneumomediastinum. Although spontaneous pneumomediastinum is usually observed in healthy young men, traumatic pneumomediastinum may be caused by blunt or penetrating trauma to the chest and neck. ⋯ Case 2 was a 23-year-old man who had a two-day history of dyspnoea and chest pain with no history of trauma. In both patients, diagnosis of pneumomediastinum was confirmed with thoracic computed tomography scans, and the condition resolved within five days of in-patient observation. In conclusion, the diagnosis of pneumomediastinum should be considered for all patients who present to the emergency department with chest pain and dyspnoea.
