Several inflammation biomarkers have been implicated in the pathogenesis and prognosis of acute coronary syndromes. However, the prognostic role of the neutrophil-lymphocyte white cell interactive response to myocardial injury in predicting short- and long-term mortality after ST elevation myocardial infarction (STEMI) remains poorly defined. ⋯ NLR based on an optimal cut off value of 7.4, was an excellent predictor of short- and long-term survival in patients with revascularized STEMI and warrants larger scale multi-center prospective evaluation, as a prognostic indicator. NLR offers improved prognostic capacity when combined with conventional clinical scoring systems, such as the Thrombolysis In Myocardial Infarction risk score.

Cardiac troponin T is a marker of myocardial injury, especially when measured by means of the high-sensitivity assay (hs-cTnT). The echocardiographic and clinical predictors of hs-cTnT may be different in ischemic heart failure (IHF) and non-ischemic dilated cardiomyopathy (DCM). ⋯ While LV-GLS is an independent predictor of hs-cTnT concentrations in patients with DCM, E/Em lateral predicted hs-TnT concentrations in patients with IHF.

Mean platelet volume (MPV) is a strong predictor of impaired angiographic reperfusion and 6-month mortality in ST-elevation myocardial infarction (MI) treated with primary percutaneous coronary intervention (PCI). No data is available for other platelet volume indices: platelet distribution width (PDW) and platelet large cell ratio (P-LCR). The aim was to assess the impact of 3 platelet volume indices on long-term prognosis in patients treated with primary PCI in acute MI. ⋯ Mean platelet volume, platelet distribution width and platelet large cell ratio measured on admission are strong, independent prognostic factors in PCI-treated acute MI.

Transfusion-related acute lung injury (TRALI) is one of the leading causes of death associated with transfusion of blood and blood components. The understanding of the etiology and pathophysiology of this syndrome has much improved during the last decades, nevertheless numerous issues are still unresolved and symptomatic treatment remains the cornerstone of medical management. ⋯ The awareness of the problem within the medical society is still unsatisfactory which results in a high number of unrecognized cases or of inaccurate diagnoses one of which is cardiogenic pulmonary edema. The aim of this review is to make the TRALI syndrome more familiar to clinicians and to emphasize how significant proper medical management is both for the patients presenting TRALI symptoms as well as for future recipients of blood components.

Under normal conditions function of the right ventricle (RV) is determined by the heart rhythm, RV filling time, RV systolic synchrony and interdependence between both ventricles. Failure of the left ventricle (LV) can lead to RV failure. Impaired function of the RV significantly worsens the prognosis in patients after myocardial infarction and with LV failure. ⋯ Frequent coexistence of chronic heart failure (CHF) and AF causes overlapping of the arrhythmia and RV dysfunction in the setting of CHF. They may lead to hemodynamic compromise and worsen prognosis in patients with chronic RV failure of various etiologies. RV structure and function can be assessed in 2D, 3D echocardiography, cardiac magnetic resonance imagingand computed tomography.
