Utilizing the prehospital ECG as a tool to bypass ER triage significantly decreases D2B times in patients with STEMI. This technology has the potential to substantially expedite reperfusion therapy in patients with STEMI.

Procedure-related complications after ICD placement are rare. Same-day discharge is safe and feasible following ICD placement for primary prevention of SCD and hence a reduction in healthcare costs can be achieved by decreasing the length of hospital stay.

SummaryBackground:Papillary muscle rupture is one of the catastrophic mechanical complications following myocardial infarction. Rupture leads to acute mitral valve regurgitation, pulmonary edema, and cardiogenic shock. Survival is dependent on prompt recognition and surgical intervention.Cases Report:We present two cases where acute myocardial infarction was complicated by papillary muscle rupture resulting in severe mitral regurgitation and cardiogenic shock. In both cases rupture occurred within one week of infarction. Both patients did not receive coronary revascularization; one patient presented late after the onset of chest pain, the other patient percutaneous revascularization attempted and was not successful. Both patients suffered an inferior wall infarction. Echocardiogram demonstrated severe mitral regurgitation with a jet directed posteriorly. In both cases rupture of the posteromedial papillary muscle resulted in flail of the anterior mitral valve leaflet, thus serving as a reminder that both the anterior and the posterior leaflets attach to both papillary muscles.Conclusions:While one case had a good outcome, the other reinforces the fact that this is a very serious complication requiring prompt recognition and treatment.

In patients with cardiac sarcoidosis, the sarcoid granulomas usually involve the myocardium or endocardium. The disease typically presents as heart failure with ventricular arrhythmias, conduction disturbances, or both. Constrictive pericarditis has rarely been described in patients with sarcoidosis: we found only 2 reports of this association. We report the case of a 57-year-old man who presented with clinical and hemodynamic features of constrictive pericarditis, of unclear cause. He was admitted for treatment of recurrent pleural effusion. After a complicated hospital course, he underwent pericardiectomy. His clinical and hemodynamic conditions improved substantially, and he was discharged from the hospital in good condition. The pathologic findings, the patient's clinical course, and his response to pericardiectomy led to our diagnosis of cardiac sarcoidosis presenting as constrictive pericarditis. In addition to the patient's case, we discuss the nature and diagnostic challenges of cardiac sarcoidosis. Increased awareness of this disease is necessary for its early detection, appropriate management, and potential cure.

Atherosclerotic renal artery disease is a common cause of hypertension and chronic kidney disease that may progress into end stage renal failure if not diagnosed and treated early. Renal artery stenosis (RAS) has been shown to be an independent risk factor for mortality in patients with coronary artery disease. We sought to determine whether race is an independent risk factor for developing RAS. A retrospective study was conducted including 324 patients with resistant hypertension who underwent renal angiography with or without coronary angiography. In univariate analysis, Caucasian race was associated with significant risk of RAS (OR = 2.3, P = .01). However, this association was no longer significant after correcting for additional clinical variables in a multivariate model (OR = 1.5, P = .07). There was a strong association between smoking and RAS (OR 2.0, P = .02). We conclude that traditional risk factors, especially smoking, rather than race, are the most important predictors of RAS development.
