Takotsubo cardiomyopathy in a bedridden patient with dementia and communication difficulties due to Alzheimer's disease.

Takotsubo cardiomyopathy is a transient wall motion abnormality of the left ventricular apex, accompanied by emotional or physical stress. Although Takotsubo cardiomyopathy is generally considered a benign disease, severe clinical complications may occur, and early detection of the disease is important. In this report, we present the case of an 86-year-old bedridden woman with a history of bronchial asthma who was transferred to our hospital because of wheezing.

Fulminant type 1 diabetes mellitus and fulminant viral myocarditis. A case report and literature review.

A 35-year-old Japanese woman was admitted with coma following flu-like symptoms. She was diagnosed with diabetic ketoacidosis and fulminant type 1 diabetes (FT1D) and received intravenous infusion of insulin and saline. The next day, the ketoacidosis disappeared, and she recovered consciousness.

Scavenger receptor A index and coronary thrombus in patients with acute ST elevation myocardial infarction.

To examine the relationship between the scavenger receptor A (SRA) index (the number of SRA+ cells observed in 10 high power fields of peripheral blood (PB) smear samples; normal upper limit <30) and coronary thrombus, 389 thrombi obtained from 393 patients with acute ST elevation myocardial infarction were examined. Thrombi were classified into platelets (PT), mixed (MT), fibrin-rich (FT) and organizing thrombi (OT); 387, 269, 57 and 29 cases were detected, respectively. Patients were divided into group A (PT only, 89 cases), B (containing MT and PT but not FT, 243 cases), and C (containing FT, 57 cases).

Impact of earthquakes on risk for pulmonary embolism.

Physical and psychological stress induced by catastrophic events such as earthquakes can lead to sudden death, acute coronary syndrome, stroke, and other cardiovascular diseases. We investigated the impact of the earthquake that occurred in Niigata, Japan, on pulmonary embolism. Pulmonary embolism increased to 9 cases in the 4 weeks after the earthquake, compared to 1 case in the 4 weeks before the earthquake, 2 cases in the corresponding 8 weeks in 2003, and 1 case in 2002.

Increase of scavenger receptor A-positive monocytes in patients with acute coronary syndromes.

To evaluate the utility of the scavenger receptor A (SRA) index (no. SRA(+) monocytes observed in 10 high-power fields of peripheral blood (PB) smear samples, normal upper limit <30) as the indication of disrupted, fissured, or eroded plaque, 225 patients with acute myocardial infarction (AMI), 79 with unstable angina (UA) and 91 with stable angina (SA) were examined. Thrombus was gathered from 95 of 205 sequential AMI patients (46.

Increased incidence of transient left ventricular apical ballooning (so-called 'Takotsubo' cardiomyopathy) after the mid-Niigata Prefecture earthquake.

Background: On October 23, 2004, a major earthquake, which registered 6.8 on the Richter scale, occurred in Niigata Prefecture in Japan. Emotional stress is important as a trigger of transient left ventricular apical ballooning (so-called 'Takotsubo' cardiomyopathy), but its incidence and clinical profile immediately after a natural disaster have not been fully elucidated.
