Lung ultrasound in acute myocardial infarction. Updating Killip & Kimball.

Background: Heart failure complicating acute myocardial infarction marks an ominous prognosis. Killip and Kimball's classification of heart failure remains a useful tool in these patients. Lung ultrasound can detect pulmonary congestion but its usefulness in this scenario is unknown.

Minor myocardial damage is a prevalent condition in patients with acute heart failure syndromes and preserved systolic function with long-term prognostic implications: a report from the CIAST-HF (Collaborative Italo-Argentinean Study on cardiac Troponin T in Heart Failure) study.

Background: Half of patients with acute heart failure syndromes (AHFS) have preserved left ventricular ejection fraction (PLVEF). In this setting, the role of minor myocardial damage (MMD), as identified by cardiac troponin T (cTnT), remains to be established.

Aim: To evaluate the prevalence and long-term prognostic significance of cTnT elevations in patients with AHFS and PLVEF.

Reduced systolic performance by tissue Doppler in patients with preserved and abnormal ejection fraction: new insights in chronic heart failure.

Background: Tissue Doppler imaging (TDI) is useful in the evaluation of systolic and diastolic function. It allows assessment of ventricular dynamics in its longitudinal axis. We sought to investigate the difference in systolic and diastolic longitudinal function in patients with chronic heart failure (CHF) with normal and reduced ejection fraction.

Cardiac troponin T levels are associated with poor short- and long-term prognosis in patients with acute cardiogenic pulmonary edema.

Background: The clinical determinants of increased cardiac troponin T (cTnT) in patients with acute cardiogenic pulmonary edema are not well defined, and the ability of this marker to predict long-term mortality has not yet been documented.

Methods: Eighty-four patients with acute cardiogenic pulmonary edema without acute myocardial infarction were prospectively enrolled. cTnT was measured in samples obtained 6 and 12 hours after admission.
