LMT AMI Caused by a Valve-Like Ridge in a 9-Year-Old Boy Successfully Treated With PCI.

A 9-year-old boy was suspected of having acute myocardial infarction and emergency coronary angiogram was performed. No signs of flow limitation in either coronary artery was detected. We performed intravascular ultrasonography from the ascending aorta, which showed a ridge on the left main trunk acting like a valve, resulting in significant stenosis.

Acarbose treatments improve arterial stiffness in patients with type 2 diabetes mellitus.

Unlabelled: Aims/Introduction:  Although the improvement of postprandial hyperglycemia by an alpha-glucosidase inhibitor (α-GI) has been associated with a risk reduction of cardiovascular events, the relationship between postprandial hyperglycemia and arterial stiffness has not been well understood. We therefore examined whether ameliorating the postprandial state by α-GI leads to an improvement in arterial stiffness.

Materials And Methods:   A total of 22 patients with type 2 diabetes mellitus were treated with acarbose.

[Usefulness of technetium-99m tetrofosmin single-photon emission computed tomography for short-term risk stratification in patients with acute chest pain in the emergency room].

Objectives: High-risk patients with acute coronary syndrome are difficult to distinguish from low-risk patients with chest pain in the emergency room. Technetium-99m (99mTc) tetrofosmin single-photon emission computed tomography (SPECT) was investigated to exclude high-risk patients with chest pain in the emergency room.

Methods: 99mTc-tetrofosmin SPECT was evaluated using a four-point scoring system in 228 patients (144 men, 84 women, mean age 68 +/- 12 years) with chest pain.
