Article Synopsis
- - The study evaluates the effectiveness of quantitative perfusion cardiac magnetic resonance (QP-CMR) imaging in detecting significant coronary artery disease (CAD) in patients with a history of CAD and new chest pain, comparing it with visual assessment of stress perfusion CMR and quantitative PET imaging.
- - Involving 145 patients with prior heart issues, the research found QP-CMR's sensitivity at 66%, which is lower than PET at 80%, but its specificity is on par with both v-CMR and PET at about 60-63%.
- - Overall, the study concludes that QP-CMR's diagnostic performance is similar to that of both other imaging methods for identifying hemodynamically significant CAD, defined by fractional
Aim: Atrial fibrillation (AF) is a rhythm disorder characterized by very rapid and disorganized atrial-derived electrical activations with uncoordinated atrial contractions. Very short periods of AF-like activity (micro-AF) may be precursors of undetected, silent episodes of atrial fibrillation. Here, we examined the relationship between natriuretic peptide concentrations and echocardiography findings in patients with micro-AF.

Objective: Sudden cardiac death or arrest describes an unexpected cardiac cause-related death or arrest that occurs rapidly out of the hospital or in the emergency room. This study aimed to reveal the relationship between coronary angiographic findings and cardiac death secondary to acute ST-elevation myocardial infarction.
Materials And Methods: Patients presenting with acute ST-elevation myocardial infarction complicated with cardiac arrest were included in the study.
Endocan may predict the presence of coronary slow flow and coronary artery disease.

Article Synopsis
- The study investigates the relationship between endocan levels and coronary artery disease (CAD) and coronary slow flow (CSF) in a group of 169 subjects undergoing coronary angiography.
- Both CAD and CSF patients exhibited significantly higher endocan levels compared to a control group, with similar levels between the two conditions, suggesting endocan's role in these diseases.
- Endocan levels, particularly when exceeding 450 pg/mL, are key predictors for both CAD and CSF, highlighting its potential as an important biomarker in these cardiovascular conditions.
