To assess the impact of spontaneous anterograde flow of the infarct artery on outcomes in patients with acute myocardial infarction (AMI), we studied 478 patients with a first anterior wall AMI who underwent coronary angiography within 12 hours after the onset of chest pain; Thrombolysis In Myocardial Infarction (TIMI) 3 flow was obtained after reperfusion(More)
BACKGROUND Peculiar asynergy, which consists of hypokinesis or akinesis from the mid portion to the apical area and hyperkinesis of the basal area on contrast left ventriculogram, is rare. Because the end-systolic left ventriculogram looks like a "tako-tsubo," which was used for trapping octopuses in Japan, we proposed the term "tako-tsubo-like left(More)
OBJECTIVE This study was undertaken to assess the relationship between acute hyperglycemia and left ventricular function after reperfusion therapy for acute myocardial infarction (AMI). METHODS This study consisted of 529 patients with a first anterior wall AMI who underwent coronary angiography followed by coronary angioplasty or thrombolysis within 12(More)
BACKGROUND Long-term moderate-intensity exercise augments endothelium-dependent vasodilation through an increase in nitric oxide (NO) production. The purpose of this study was to determine the effects of different intensities of acute exercise on hemodynamics in humans. METHODS We evaluated forearm blood flow (FBF) responses to different intensities of(More)
BACKGROUND Bone-marrow mononuclear cell (BM-MNC) implantation improves ischemic symptoms in patients with critical limb ischemia (CLI). The purpose of this study was to evaluate long-term clinical outcomes after autologous BM-MNC implantation in patients with CLI. METHODS AND RESULTS We assessed long-term clinical outcomes after BM-MNC implantation in 51(More)
BACKGROUND Therapeutic hypothermia (TH) is a standard strategy to reduce brain damage in post-cardiac arrest syndrome (PCAS) patients. However, it is unknown whether the target temperature should be adjusted for PCAS patients in different states. METHODS Participants in the J-PULSE-Hypo study database were divided into lower (32.0-33.5 °C; Group L) or(More)
OBJECTIVES We sought to assess myocardial perfusion and metabolism in patients with peculiar transient asynergy, which consisted of basal normokinesia and apical akinesia of the left ventricle (LV) at the same time. BACKGROUND This asynergy has been widely called "tako-tsubo-like LV dysfunction" in Japan, but little is known about its pathophysiology. (More)
Caffeine is the most widely used pharmacologic substance in the world. It is found in common nonessential grocery items (e.g., coffee, tea, cocoa, and chocolate). The effects of caffeine on cardiovascular diseases, including hypertension, remain controversial, and there is little information on its direct effect on vascular function. The purpose of this(More)
OBJECTIVE Smoking is associated with endothelial dysfunction and activated Rho-kinase in vascular smooth muscle cells (VSMCs) in humans. The purpose of this study was to elucidate the relationship between endothelial function and Rho-kinase activity in forearm VSMCs in healthy young men. METHODS AND RESULTS We evaluated the forearm blood flow (FBF)(More)
Residual risk of cardiovascular events after treatment with stain might be explained in part because patients have low levels of n-3 polyunsaturated fatty acids (PUFA). We examined how lipid-lowering therapy with strong statin affected serum PUFA levels in patients with coronary artery disease. The study population consisted of 46 patients with coronary(More)
