Penetrating cardiac trauma carries high mortality rates. It has been commonly associated with stabbing, but increasing urban violence has led to growing numbers of gunshot heart wounds. The latter have higher mortality rates among penetrating cardiac injuries and may affect multiple heart chambers, with mortality rates even higher. We report ...

3,5,3'-Levo-triiodothyronine (L-T3) is essential for DNA transcription, mitochondrial biogenesis and respiration, but its circulating levels rapidly decrease after myocardial infarction (MI). The main aim of our study was to test whether an early and sustained normalization of L-T3 serum levels after MI exerts myocardial protective effects through a mitochondrial preservation. ...

Toxic cardiac arrest is an uncommon manifestation of poisoning. Patients might benefit from resuscitative measures that are over and above those recommended in standard ACLS resuscitation guidelines. Extraordinary resuscitative measures might include the use of toxin-specific antidotes, prolonged CPR and/or other measures to bypass the poisoned myocardium (such as extra-corporeal ...

Prolonged ischemia causes cellular necrosis and myocardial infarction (MI) via intracellular calcium (Ca(2+)) overload. Manganese-enhanced MRI indirectly assesses Ca(2+) influx movement in vivo as manganese (Mn(2+)) is a Ca(2+) analog. To characterize myocardial Mn(2+) efflux properties, T(1)-mapping manganese-enhanced MRI studies were performed on adult male C57Bl/6 mice in which Ca(2+) ...

Previously, 7-[2-[4-(4-nitrobenzene)piperazinyl]ethyl]-1, 3-dimethylxanthine (KMUP-3) has been shown to induce aortic smooth muscle relaxation through K(ATP) channel opening and endothelial nitric oxide synthase (eNOS) enhancement. We further investigated whether KMUP-3 protects against myocardial remodelling after myocardial infarction (MI), and whether KMUP-3 increases the expression of eNOS in MI rats. Wistar rats ...

The automated external defibrillator (AED), in combination with effective cardiopulmonary resuscitation (CPR), is a critical part of the American Heart Association's "Chain of survival." Newer guidelines have simplified resuscitation and emphasized the importance of CPR in providing rapid and deep compressions with minimal interruptions; in fact, CPR should resume immediately ...

Cocaine use is a known cause of chest pain and acute myocardial infarction and frequently leads to cardiac catheterization procedure. The treatment of cocaine-related acute coronary syndromes presents unique challenges because a variety of mechanisms including atherosclerotic plaque rupture, platelet activation, and coronary vasospasm may contribute to the pathogenesis. Our ...

Whether myocardial perfusion grade (MPG) following late recanalization of infarct-related arteries (IRAs) predicts left ventricular (LV) function recovery beyond the acute phase of myocardial infarction (MI) is unknown. The Total Occlusion Study of Canada-2 enrolled stable patients with a persistently occluded IRA beyond 24 hours and up to 28 days ...

Right ventricular infarction (RVI) during inferior myocardial infarction (MI) is readily diagnosed when ST-segment elevation (STE) is recorded in lead V4R. RVI may also yield precordial STE and such an electrocardiographic (ECG) pattern may be misinterpreted as a sign of anterior MI. We present a case of inferior-right ventricular (RV) ...

After a myocardial infarction (MI), an episode of ischemia-reperfusion (I/R) can result in a greater impairment of left ventricular (LV) regional function (LVRF) than that caused by an initial I/R episode in the absence of MI. Membrane type-I matrix metalloproteinase (MT1-MMP) proteolytically processes the myocardial matrix and is upregulated in ...

WHO has played a leading role in the formulation and promulgation of standard criteria for the diagnosis of coronary heart disease and myocardial infarction since early 1970s. The revised definition takes into consideration the following: well-resourced settings can use the ESC/ACC/AHA/WHF definition, which has new biomarkers as a compulsory feature; ...

Clusterin (Apolipoprotein J), a plasma protein with cytoprotective and complement-inhibiting activities, localizes in the infarcted heart during myocardial infarction (MI). Recently, we have shown a protective effect of exogenous clusterin in vitro on ischaemically challenged cardiomyocytes independent of complement. We therefore hypothesized that intravenous clusterin administration would reduce myocardial infarction ...

Existing models for outcome after percutaneous coronary interventions (PCIs) lack assessment of long-term prognosis. Our goal was to derive 1- and 5-year mortality and mortality/myocardial infarction (MI) risk models for PCI outcomes from simple, easily obtainable clinical and laboratory variables. Using the Mayo Clinic registry, we analyzed long-term mortality and ...

BACKGROUND: Carotid intima-media thickness (CIMT) is increasingly being used as a surrogate end point in randomized control trials (RCTs) of novel cardiovascular therapies. However, it remains unclear whether changes in CIMT that result from these therapies correlate with nonfatal myocardial infarction (MI). METHODS: We performed a literature search of RCTs ...

A positive family history for myocardial infarction (MI) is known to be a major cardiovascular risk factor. The current European guidelines therefore recommend intensified primary prevention for the siblings and children of persons who have had an MI. Although the genes underlying the heritable component of MI were largely unknown ...

We previously reported serum C-reactive protein (CRP) elevation after acute myocardial infarction (MI) to be associated with adverse outcomes including cardiac rupture, left ventricular (LV) remodeling, and cardiac death. Experimental studies have indicated that CRP per se has various biological actions including proinflammatory and proapoptotic effects, suggesting a pathogenic role ...

BACKGROUND: Growing evidence suggests that intramyocardial biomaterial injection improves cardiac functions after myocardial infarction (MI) in rodents. Cell therapy is another promising approach to treat MI, although poor retention of transplanted cells is a major challenge. In this study, we hypothesized that intramyocardial injection of self-assembling peptide nanofibers (NFs) thickens ...

Clopidogrel is beneficial after ACS. Recent data suggest the superiority of prasugrel or ticagrelor compared with clopidogrel. However, there is no comparison of prasugrel vs. ticagrelor. We performed an adjusted indirect meta-analysis comparing prasugrel vs. ticagrelor for acute coronary syndromes (ACSs). Randomized trials were searched in PubMed. The primary end-point ...
