Direct comparison of high-sensitivity cardiac troponin T and I in the early differentiation of type 1 vs. type 2 myocardial infarction.

Aims: To directly compare the diagnostic accuracy of high-sensitivity cardiac troponin (hs-cTn) T vs. hs-cTnI in the early non-invasive differentiation of Type 1 myocardial infarction (T1MI) due to plaque rupture and atherothrombosis from Type 2 myocardial infarction (T2MI) due to supply-demand mismatch.

Methods And Results: In a prospective multicentre diagnostic study, two independent cardiologists centrally adjudicated the final diagnosis of T1MI vs.

Incremental value of high-frequency QRS analysis for diagnosis and prognosis in suspected exercise-induced myocardial ischaemia.

Aim: Exercise stress testing is used to detect myocardial ischaemia, but is limited by low sensitivity and specificity. The authors investigated the value of the analysis of high-frequency QRS components as a marker of abnormal depolarization in addition to standard ST-deviations as a marker of abnormal repolarization to improve the diagnostic accuracy.

Methods And Results: Consecutive patients undergoing bicycle exercise stress nuclear myocardial perfusion imaging were prospectively enrolled.

Ultrasound indications for maternal STORCH testing in pregnancy.

Aims Of The Study: Fetal abnormalities found on ultrasonography lead to a variety of diagnostic procedures, including a panel of serologies to detect possible maternal STORCH infections encompassing syphilis, Toxoplasma gondii, rubella, cytomegalovirus, herpes simplex, and others (human immunodeficiency virus, hepatitis B and C, parvovirus B19, enterovirus, varicella zoster, and Leptospira interrogans). The value of indiscriminate testing for infections upon the detection of fetal ultrasound abnormalities has been questioned. The aim of this study was to review the ultrasonographic abnormalities leading to maternal STORCH panels at the obstetrics department of a university hospital.
