- Using a fluid-filled wire with a pressure sensor outside the patient compared to a conventional pressure wire may avoid the systematic error introduced by the hydrostatic pressure within the coronary circulation.To assess the safety and effectiveness of the novel fluid-filled wire, Wirecath (Cavis Technologies, Uppsala, Sweden), as well as its ability to avoid the hydrostatic pressure error.The Wirecath pressure wire was used in 45 eligible patients who underwent invasive coronary angiography and had a clinical indication for invasive coronary pressure measurement at Sahlgrenska University Hospital, Gothenburg, Sweden. In 29 patients, a simultaneous measurement was performed with a conventional coronary pressure wire (PressureWire X, Abbott Medical, Plymouth, MN, USA), and in 19 patients, the vertical height difference between the tip of the guide catheter and the wire measure point was measured in a 90-degree lateral angiographic projection. No adverse events caused by the pressure wires were reported. The mean Pd/Pa and mean FFR using the fluid-filled wire and the sensor-tipped wire differed significantly; however, after correcting for the hydrostatic effect, the sensor-tipped wire pressure correlated well with the fluid-filled wire pressure (R=0.74 vs. R=0.89 at rest and R=0.89 vs. R=0.98 at hyperemia).Hydrostatic errors in physiologic measurements can be avoided by using the fluid-filled Wirecath wire, which was safe to use in the present study. This trial is registered with NCT04776577 and NCT04802681.

- The number of elderly persons with cardiovascular disease is increasing. In Sweden, the incidence of acute myocardial infarction is the highest among individuals aged 85 years and over. However, there is still little evidence about whether this population benefits from established treatments. Furthermore, the values and preferences of octogenarians (age ⩾80 years), as well as how they could be involved in treatment decisions, have been largely overlooked in research. Overall, increased knowledge about the preferences and expectations of octogenarians is needed to incorporate their treatment expectations into the decision-making process.This study aimed to describe the treatment choice preferences and post-treatment life expectations of octogenarians with acute coronary syndrome.A total of 19 patients (eight women, 11 men) aged 80 years and older and diagnosed with non-ST-elevation myocardial infarction or unstable angina were enrolled in this qualitative study. Data were collected between May 2011 and June 2013 through semistructured interviews. The data were analysed using qualitative content analysis.We identified two main categories: Wanting the best and Hope for increased wellbeing. Participant preferences were influenced by their own and others' previous experiences and their confidence in healthcare professionals. With respect to treatment outcomes, the participants hoped to get well, stay active, experience fewer symptoms and regain vitality.The studied octogenarians desired the best treatment option and trusted that their healthcare providers will make appropriate recommendations. These patients expected their treatment to result in increased wellbeing and fewer symptoms.
