Cardiovascular Outcomes in Patients With Previous Myocardial Infarction and Mild Diabetes Mellitus Following Treatment With Pioglitazone: Reports of a Randomised Trial From The Japan Working Group for the Assessment Whether ioglitazone rotects DM Patients gainst e-Infarction (PPAR Study).

Background: Secondary prevention in patients with myocardial infarction (MI) is critically important to prevent ischaemic heart failure and reduce social burden. Pioglitazone improves vascular dysfunction and prevents coronary atherosclerosis, mainly via anti-inflammatory and antiatherogenic effects by enhancing adiponectin production in addition to antihyperglycemic effects, thus suggesting that pioglitazone attenuates cardiovascular events in patients with mild (HbA1c levels < 6·5%) diabetes mellitus (DM). Therefore, we evaluated the effects of pioglitazone on cardiovascular events in patients with both previous MI and mild DM.

Comparison of anti-inflammatory effects of rivaroxaban vs. dabigatran in patients with non-valvular atrial fibrillation (RIVAL-AF study): multicenter randomized study.

Some experimental studies have shown that direct oral anticoagulants (DOACs) have anti-inflammatory effects. However, the interval changes in inflammatory markers in patients with non-valvular atrial fibrillation (AF) who receive DOACs remain unknown. Between July 2013 and April 2014, a total of 187 AF patients randomly assigned to receive rivaroxaban (n = 91) or dabigatran (n = 96) were assessed for eligibility.

Takotsubo Cardiomyopathy in a Patient with Previously Undiagnosed Hypertrophic Cardiomyopathy with Latent Obstruction.

A 62-year-old woman with takotsubo cardiomyopathy (TCM) accompanied by cardiogenic shock due to the obstruction of left ventricular outflow tract (LVOT) and massive mitral regurgitation (MR) was admitted to the emergency department. After successful treatment with intensive care, dobutamine stress-echocardiography was performed, which reproduced a dynamic LVOT gradient, severe MR and cardiogenic shock. A histological examination obtained from the right ventricular septum demonstrated hypertrophied and bizarre myocytes, with myocyte disarray.

Current status of emergency care for ST-elevation myocardial infarction in an urban setting in Japan.

Background: The door-to-balloon time (DTB) is an important predictor of the outcome for patients with ST-elevation myocardial infarction (STEMI). In Japan, percutaneous coronary intervention (PCI) can be performed at many hospitals, and the predominant strategy for reperfusion therapy is primary PCI. However, it remains unclear how rapidly reperfusion is achieved at these hospitals.

Serum lipoprotein(a) level and clinical coronary stenosis progression in patients with myocardial infarction: re-revascularization rate is high in patients with high-Lp(a).

Background: High serum lipoprotein(a) (Lp(a)) levels are associated with coronary artery disease.

Methods And Results: The serum Lp(a) levels of 130 patients with acute myocardial infarction (AMI) who underwent direct percutaneous coronary intervention were investigated. On the basis of Lp(a) level at 1 month after the onset of AMI, the patients were classified into 2 groups (high-Lp(a) (> or =30 mg/dl) and low-Lp(a) (< 30 mg/dl)) for evaluation of the clinical coronary stenosis progression (CCSP) rate.
