Real-World Data on Potent P2Y12 Inhibition in Patients with Suspected Chronic Coronary Syndrome, Referred for Coronary Angiography.

Introduction: Potential benefit with potent platelet inhibition in patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI) has been discussed. The aim of this study was to compare a potent P2Y12 inhibition strategy using ticagrelor with clopidogrel in CCS patients referred for coronary angiography (CA) and PCI if feasible.

Methods: In this retrospective real-world study, patients referred for outpatient CA due to suspected CCS were included.

Transradial versus trans-femoral access site in high-speed rotational atherectomy in Sweden.

Background: Radial artery is the preferred access site in contemporary percutaneous coronary intervention (PCI). However, limited data exist regarding utilization pattern, safety, and long-term efficacy of transradial artery access (TRA) PCI in heavily calcified lesions using high-speed rotational atherectomy (HSRA).

Methods: All patients who underwent HSRA-PCI in Sweden between 2005 and 2016 were included.

Management of latent Mycobacterium tuberculosis infection: WHO guidelines for low tuberculosis burden countries.

Latent tuberculosis infection (LTBI) is characterised by the presence of immune responses to previously acquired Mycobacterium tuberculosis infection without clinical evidence of active tuberculosis (TB). Here we report evidence-based guidelines from the World Health Organization for a public health approach to the management of LTBI in high risk individuals in countries with high or middle upper income and TB incidence of <100 per 100 000 per year. The guidelines strongly recommend systematic testing and treatment of LTBI in people living with HIV, adult and child contacts of pulmonary TB cases, patients initiating anti-tumour necrosis factor treatment, patients receiving dialysis, patients preparing for organ or haematological transplantation, and patients with silicosis.
