Coronary lesion type, location, and characteristics of acute ST elevation myocardial infarction in young adults under 35 years of age.

Objective: In the present study, we attempted to analyze the coronary artery lesion characteristics of acute ST elevation myocardial infarction (STEMI) in young patients (aged less than 35 years).

Methods: We retrospectively surveyed 25 038 coronary angiography procedures, which were carried out at The Baskent University Adana Hospital from 1998 to present, to discover acute STEMI in young patients. We studied clinical risk factors and angiographic characteristics in 42 consecutive patients who underwent primary coronary angiography for acute STEMI.

Correlation between QTc interval and clinical severity of subarachnoid hemorrhage depends on the QTc formula used.

Objectives: Subarachnoid hemorrhage (SAH) frequently prolongs QT interval in the acute phase. The purpose of our study is to investigate whether the correlation between electrocardiographic corrected QT interval and the clinical severity of SAH depends on QTc formula used.

Methods: We retrospectively studied 52 consecutive subjects with nontraumatic SAH (extravasation of blood into the spaces covering the central nervous system that are filled with cerebrospinal fluid) who were admitted within the first day of SAH.
