Myocardial stunning and hibernation have been subjects of intense laboratory and clinical investigations to elucidate mechanisms responsible for contractile dysfunction after transient ischemia or chronic hypoperfusion. Considerable evidence has implicated the generation of oxygen-derived free radicals and derangements in myocardial energy metabolism and excitation-contraction coupling as major...
According to recent researches about the importance of prognostic value of QT dispersion (QTD) in patients with acute myocardial infarction , the present study was performed to assess the relationship between QT dispersion increment and incidence of ventricular fibrillation in patients with acute myocardial infarction. &nb...
we discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. th e most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. moreover, since the systemic involvement of the di...
Background: Myocardial injury, defined by elevated troponin levels, is associated with adverse outcome in patients coronavirus disease 2019 (COVID-19). The frequency of cardiac injury remains highly uncertain and confounded current publications; myocarditis one several mechanisms that have been proposed. Methods: We prospectively assessed myocardial hospitalized for COVID-19 using transthoracic...
Coronary artery disease (CAD) is the most prevalent and single most common cause of morbidity and mortality [1] with the resulting left ventricular (LV) dysfunction an important complication. The distinction between viable and non-viable myocardium in patients with LV dysfunction is a clinically important issue among possible candidates for myocardial revascularization. Several available non-in...
