AIMS: Coronary artery disease is common in patients with end-stage renal failure (ESRF). However, there is little evidence that revascularisation improves outcomes, compared with medical management. This study assessed survival and cardiovascular outcomes in patients with ESRF undergoing coronary angiography and then having coronary artery bypass graft (CABG) surgery, percutaneous coronary intervention (PCI) or medical management. METHODS: Survival and major adverse cardiac events (MACE) were examined in all patients with ESRF who underwent coronary angiography at Auckland City Hospital between 2003 and 2012...

Mechanical compression devices enable transportation of patients with cardiac arrest to the catheterization laboratory. Coronary angiography and coronary interventions can be performed while the patients are being resuscitated with these devices. In this report, we describe three cases in whom resuscitation with mechanical compression devices and rapid transportation to the catheterization laboratory resulted in favorable cardiac and neurological outcome.

BACKGROUND: Napkin-ring sign (NRS) is an independent prognostic imaging marker of major adverse cardiac events. However, identification of NRS is challenging because of its qualitative nature. Radiomics is the process of extracting thousands of quantitative parameters from medical images to create big-data data sets that can identify distinct patterns in radiological images. Therefore, we sought to determine whether radiomic analysis improves the identification of NRS plaques. METHODS AND RESULTS: From 2674 patients referred to coronary computed tomographic angiography caused by stable chest pain, expert readers identified 30 patients with NRS plaques and matched these with 30 non-NRS plaques with similar degree of calcification, luminal obstruction, localization, and imaging parameters...

BACKGROUND: Cardiac computed tomography angiography (cardiac CTA) is an increasingly used versatile imaging method to evaluate coronary and cardiac morphology. Owing to improvements in technology, image quality has continuously improved over the last 10-20 years. At the same time, numerous non-randomized and randomized studies have been performed to reduce the associated radiation exposure. Currently, it is unclear if the advances in technology and knowledge about radiation reduction translated into reduced levels of cardiac CTA radiation dose in daily clinical practice as well as a wide utilization of dose-saving strategies...

BACKGROUND AND AIMS: Periodontitis, a common polymicrobial inflammatory disease in the tooth supporting tissues, is a risk factor for coronary artery disease. One of the proposed underlying mechanisms is the systemic immune response to periodontal infection. We studied how serum antibodies against seven periodontal pathogens and their subgingival levels associate with each other, periodontitis, and coronary artery disease. METHODS: The Parogene cohort included 505 Finnish patients (mean age 63 y) who underwent coronary angiography, and clinical and radiographic oral examinations...
