A 35-year-old postpartum woman was transferred to our emergency room because of severe precordial pain on the 49th day after delivery. Her ECG up on admission showed ST elevations in leads II, III, and aVF, and an emergency coronary angiography (CAG) demonstrated thrombosis in segment #1 and obstruction in segment #2 of the right coronary artery. Although percutaneous transluminal coronary angioplasty (PTCA) was performed immediately to dilate the stenotic and obstructive regions with balloons, it was not possible to achieve sufficient coronary blood flow TIMI grade 3 coronary blood flow was restored, however, through intracoronary thrombolysis.

In a 58-year-old male, upper digestive endoscopy revealed a protruding lesion in the esophagus on a medical examination. The patient was referred to the Department of Surgery in our hospital to undergo surgery. On the initial consultation, upper digestive endoscopy showed a smooth, soft, black purple, type II protruding lesion measuring approximately 25 mm at 35 cm apart from the incisor.

Several studies have reported that the use of a distal protection device decreases the incidence of slow-flow and/or no-reflow in patients with myocardial infarctions. In the present study, we investigated the influence of a RESCUE/Thrombuster system and a PercuSurge GuardWire catheter on coronary microcirculation disorders in patients with acute myocardial infarction using the natriuretic polypeptide (ANP), the brain natriuretic peptide (BNP), and (99m)Tc-tetrofosmin myocardial scintigraphy (TF). The group consisted of a 77 patients with initial inferior myocardial infarction who had undergone emergency coronary angioplasty.

Inflammatory cytokines are suspected to play an important role in the pathophysiology of left ventricular (LV) remodeling. We investigated whether high-sensitivity C-reactive protein (CRP) (hs-CRP) is a predictor for LV remodeling in patients with acute myocardial infarction (AMI) with successful reperfusion, and also whether such a situation can be avoided by the administration of angiotensin-converting enzyme inhibitors (ACEI) or angiotensin II receptor blockers (ARB). The subjects were 139 patients with an initial attack of anterior myocardial infarction successfully treated by reperfusion therapy.
