Coronary air embolism is a rare event. We report a case in which an acute myocardial infarction occurred in the region supplied by the right coronary artery after the removal of a double-lumen hemodialysis catheter. Emergent coronary angiography revealed air bubbles obstructing the mid-segment of the right coronary artery with slow flow phenomenon distally. The patient expired due to myocardial...

Angina in the presence of intact coronary arteries remains a relatively frequent clinical issue. It is now well understood that an impairedcapacity to modulate coronary vascular resistances upon exercise (i.e. an impaired coronary flow reserve) may lead to ischemia and angina.We describe a case of coronary slow flow, i.e. a condition in which resting (micro) vascular resistances are ina...

INTRODUCTION Slow coronary flow (SCF) is described as the slow passage of contrast to distal coronaries despite anatomically normal coronary arteries. It has been shown that increased serum prolidase activity (SPA) correlates with collagen turnover. Increased collagen turnover might be associated with the development of atherosclerotic plaques. AIM To investigate the relationship between seru...

We would like to thank sincerely Balta et al. (1) for their positive comments and kind interest concerning our original research article that was recently published in Clinics (2). As indicated in the authors’ comments, red cell distribution width (RDW) is a measurement of the size variation in red blood cells, as well as an index of the heterogeneity of the circulating erythrocytes, which is c...
