We investigated whether a high white blood cell (WBC) count on admission for acute myocardial infarction (AMI) may be associated with a higher risk of subsequent left ventricular (LV) remodeling. We included 107 patients with anterior AMI. Echocardiographic studies were performed at hospital discharge, at 3 months, and at 1 ...

Cardiac troponin is the standard biomarker for the diagnosis of acute myocardial infarction (AMI) and risk stratification for short-term adverse cardiac events (death, AMI or need for revascularization). Unfortunately, the concentration of troponin in blood is normal in AMI patients who present early after the onset of symptoms. As such, ...

Acute mesenteric ischemia (AMI) is an abdominal emergency with a high mortality. Prompt revascularization can prevent intestinal infarction and reduce mortality. We report three cases of acute occlusive mesenteric ischemia without signs of intestinal necrosis, which were successfully managed with endovascular interventions. Mechanical thrombus fragmentation was performed and underlying chronic ...

Genetic factors are thought to contribute to the pathogenesis of acute myocardial infarction (AMI). A common variant of factor XIII (FXIII), FXIII Val34Leu, may be protective against developing an AMI, but various studies show conflicting results. We performed a meta-analysis to determine whether the FXIII Val34Leu variant is associated with ...

Dynamic intraventricular obstruction is a less well-known mechanical complication of acute myocardial infarction (AMI). Its hallmark is the development of a new systolic murmur, and echocardiography is necessary for diagnosis. We describe a case of a 74-year-old woman with dynamic intraventricular obstruction complicating AMI. Serial echocardiography suggested that the intraventricular ...

Nitroprusside (NTP) is used for the treatment of slow coronary flow (SCF) after coronary interventions. The wide variation in dosage, route, and timing of its administration in the reported studies prevents an objective assessment of its efficacy. We report the incidence and response to a standardized NTP protocol of SCF ...

It is now recognized that changes occurring during cardiac remodeling may influence the tolerance of the myocardium to ischemic stress. Therefore, the present study investigated the response of the post-infarcted heart to ischemia in an experimental model of ischemia and reperfusion injury and the possible underlying mechanisms. Acute myocardial infarction ...
