A 51-year-old man was being admitted to the emergency department with chest pains. He had a history of acute myocardial infarction (MI) on two prior occasions and was successfully treated with drug eluting stents. He was diagnosed with 3 consecutive events of acute MI in 3 different vessels. The consecutive events of acute MI in different vessels are a very rare case. He did not have risk facto...

The purpose of this study is to investigate the impact oxygen therapy on cardiovascular outcomes in relation sex patients with confirmed myocardial infarction (MI). DETermination role Oxygen suspected Acute Myocardial Infarction trial randomized 6,629 at 6 L/min for 6-12 hours or ambient air. In present subgroup analysis including 5,010 (1,388 women and 3,622 men) MI, we report effect supplemen...

OBJECTIVES This study aimed to determine whether remote ischemic conditioning (RIC) initiated prior to primary percutaneous coronary intervention (PPCI) could reduce myocardial infarct (MI) size in patients presenting with ST-segment elevation myocardial infarction. BACKGROUND RIC, using transient limb ischemia and reperfusion, can protect the heart against acute ischemia-reperfusion injury. ...

Abstract Background: Early diagnosis of right ventricle (RV) involvement in inferior myocardial infarction (Inf MI) is very critical. This study was performed to evaluate the clinical findings of Inf MI with or without RV infarction. Methods: From September 2010 to September 2012, 195 patients with definite diagnosis of Inf MI were evaluated in the Department of Cardiology, in Babol, north of...

The term acute coronary syndrome (ACS) describes the spectrum of disease from acute myocardial infarction (MI) to unstable angina, as described in the first article of this feature (p285).The primary cause of these diseases is essentially the same — thrombosis of a coronary artery leading to ischaemia and possibly infarction of the myocardium.The degree of ischaemia or infarct size is related t...

In this issue of the Journal, Pinney and Wasserman describe the case of a patient who survives acute aortic dissection complicated by occlusion of the left main coronary ostium and anterior myocardial infarction (MI), due in part to the fortuitous presence of an anomalous left circumflex artery. The case illustrates the challenges of diagnosing aortic dissection, even in the current era of accu...

conclusions we showed that patients with metabolic syndrome have larger infarct size compared to control subjects. background infarct size is an important surrogate end point for early and late mortality after acute myocardial infarction. despite the high prevalence of metabolic syndrome in patients with atherosclerotic diseases, adequate data are still lacking regarding the extent of myocardia...

Disruption of vulnerable or high-risk plaques is the common pathophysiological mechanism of acute coronary syndromes with or without ST elevation. The reflection of the same pathophysiological mechanism differs in non-ST-elevation acute coronary syndromes and ST-elevation myocardial infarction (STEMI) in terms of clinical presentation, prognosis and therapeutic approach. Diagnostic and therapeu...

A large body of evidence produced during decades of research indicates that myocardial injury activates innate immunity. On the one hand, innate immunity both aggravates ischemic injury and impedes remodeling after myocardial infarction (MI). On the other hand, innate immunity activation contributes to myocardial healing, as exemplified by monocytes' central role in the formation of a stable sc...

Background: Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI) could be used for assessing sheep myocardium following an acute myocardial infarction (MI) and response to int...
