Introduction: Regarding the complications and costs of CT imaging for patients, this study aimed at investigating the necessity of CT scans in patients visiting the emergency unit with first-onset seizure.

Methods: One hundred patients who had experienced their first seizure were enrolled. Their CT scan was studied, and based on the radiology report, the type of probable pathologies and their percentage were determined.

Results: The patient's mean age was 39.78±17.43 yrs. CT scan abnormalities were reported in 27 cases as follows: nonspecific senile changes in 11 (40.7%), encephalomalacia in 3 (11.1%), acute infarct in 5 (18.5%), lacunar infarct in 3 (11.1%), mass-like lesion in 4 (14.8%) and cerebral venous thrombosis (CVT) evidence in 1 (3.7%). Acute infarct and mass-like lesions were seen together in the CT scan of one patient. In only 9 of the 27 abnormal CT scans, the findings were in accordance with seizure consisting of an acute infarct, mass-like lesion, and CVT evidence.

Discussion: It seems that performing a CT scan in all patients referring to the emergency department with a first-onset seizure is not necessary.

Background: He's team have recently developed a new Coronary Artery Tree description and Lesion EvaluaTion (CatLet) angiographic scoring system, which is capable of accounting for the variability in coronary anatomy, and risk-stratifying patients with coronary artery disease. Preliminary studies have demonstrated its superiority over the the Synergy between percutaneous coronary intervention with Taxus and Cardiac Surgery (SYNTAX) score with respect to outcome predictions for acute myocardial infarction (AMI) patients. However, there are fewer studies on the prognostic in chronic coronary artery disease(CAD).

Acute myocardial infarction (AMI) remains one of the most common causes for cardiogenic shock (CS), with high inpatient mortality (40-50 %). Studies have reported the use of pulmonary artery catheters (PACs) in decompensated heart failure, but contemporary data on their use to guide management of AMI-CS and in different SCAI stages of CS are lacking. We investigated the association of PACs and clinical outcomes in AMI-CS.

Introduction: Cardiogenic shock (CS) is marked by substantial morbidity and mortality. The two major CS etiologies include heart failure (HF) and acute myocardial infarction (AMI). The utilization trends of mechanical circulatory support (MCS) and their clinical outcomes are not well described.

Cardiologists and gastroenterologists often encounter the coexistence of symptoms and functional abnormalities, but determining causation is more difficult.​​ In 1962 Smith and Papp first coined the term "linked angina". Their statement was preceded by the experiment whereby increase in bile duct pressure elicited the typical chest pain in patients with ischemic heart disease.
