Cardiac arrest, though not common during coronary angiography, is increasingly occurring in the catheterization laboratory because of the expanding complexity of percutaneous interventions (PCI) and the patient population being treated. Manual chest compression in the cath lab is not easily performed, often interrupted, and can result in the provider experiencing excessive radiation exposure. Mechanical cardiopulmonary resuscitation (CPR) provides unique advantages over manual performance of chest compression for treating cardiac arrest in the cardiac cath lab. Such advantages include the potential for uninterrupted chest compressions, less radiation exposure, better quality chest compressions, and less crowded conditions around the catheterization table, allowing more attention to ongoing PCI efforts during CPR. Out-of-hospital cardiac arrest patients not responding to standard ACLS therapy can be transported to the hospital while mechanical CPR is being performed to provide safe and continuous chest compressions en route. Once at the hospital, advanced circulatory support can be instituted during ongoing mechanical CPR. This article summarizes the epidemiology, pathophysiology and nature of cardiac arrest in the cardiac cath lab and discusses the mechanics of CPR and defibrillation in that setting. It also reviews the various types of mechanical CPR and their potential roles in and on the way to the laboratory. (Circ J 2016; 80: 1292 -1299

Empiric antibiotic usage is very common in clinical practice and Trimethoprim-Sulfamethoxazole (TMP-SMX) is one such antibiotic used extensively in primary care practice. Some patients experience serious adverse effects to the antibiotics that markedly increase the morbidity and the cost of medical care. We describe one such patient, a previously healthy 40-year-old Hispanic female who developed myositis and rhabdomyolysis secondary to TMP-SMX. To the best of our knowledge, this is the first report of TMP-SMX-induced rhabdomyolysis in an immunocompetent host.

Few patients at this center with LE-PAD underwent arterial revascularization. After adjusting for baseline differences, there is a trend toward lower 5-year mortality in those undergoing LE arterial revascularization when compared to those who do not.
