The Effect of Daylight-Saving Time on Percutaneous Coronary Intervention Outcomes in Acute Coronary Syndrome Patients-Data from the Polish National Registry of Percutaneous Coronary Interventions (ORPKI) in the Years 2014-2022.

INTRODUCTION: Many factors related to the switch to summer/winter time interfere with biological rhythms. OBJECTIVES: This study aimed to analyze the impact of time change on clinical outcomes of patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI). PATIENTS AND METHODS: Electronic data of 874,031 patients with ACS who underwent invasive procedures were collected from the Polish National Register of Interventional Cardiology Procedures (ORPKI) between 2014 and 2021. We determined the number of patients undergoing PCI and periprocedural mortality during the day of spring or autumn time change and within the first 3 and 7 days after the time change. RESULTS: We demonstrated the impact of time changes on the periprocedural mortality of ACS patients within 1 day and the period of 3 and 7 days from the time change. We observed that the occurrence of all ACS and NSTEMI on the first day was lower for both time changes and higher in the case of UA and spring time change. The autumn time change significantly reduced the occurrence of all types of ACS. A significant decrease in the number of invasive procedures was found after autumn transition in the period from the first day to 7 days for ACS, NSTEMI, and UA. CONCLUSIONS: The occurrence of ACS and the number of invasive procedures were lower for both changes over time. Autumn time change is associated with increased periprocedural mortality in ACS and a less frequent occurrence of UA and NSTEMI within 7 days.

Factors determining the frequency of optical coherence tomography and intravascular ultrasound use in patients treated with percutaneous coronary interventions in recent years: Analysis based on a large national registry.

BACKGROUND: Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have demonstrated improvement in the clinical outcome of patients undergoing percutaneous coronary intervention (PCI). AIMS: We aimed to examine the frequency of implementing OCT and IVUS during coronary angiography (CA) and PCI in everyday practice in Poland. Factors related to the more common choice of these imaging techniques were determined. METHODS: Data from the Polish National Registry of Percutaneous Coronary Interventions (ORPKI) were procured for analysis. Between January 2014 and December 2021, we extracted data on 1 452 135 CAs, 11 710 using IVUS (0.8%) and 1471 with OCT (0.1%) and 838 297 PCIs, 15 436 with IVUS (1.8%) and 1680 with OCT (0.2%). We assessed the determining factors for applying IVUS and OCT via multiple regression logistics models. RESULTS: The frequency of applying IVUS during CAs and PCIs increased significantly between the years 2014 and 2021. In 2021, it reached 1.54% for CAs and 4.42% for PCIs, while for OCT, there was a rise regarding the CA group, namely 0.13% in 2021, and, in the PCI group, 0.43%. Age was one of the factors significantly associated with the frequency of using IVUS/OCT during CA/PCI, which was confirmed by multivariate analysis (Odds ratio: 0.981 for IVUS and 0.973 for OCT use with PCI). CONCLUSION: The frequency at which IVUS and OCT were used has undergone a significant increase in previous years. This increase can be largely attributed to the current reimbursement policies. Further improvement is required for this frequency to be at a satisfactory level.

The Effect of COVID-19 on the Perioperative Course of Acute Coronary Syndrome in Poland: The Estimation of Perioperative Prognosis and Neural Network Analysis in 243,515 Cases from 2020 to 2021.

COVID-19 causes thromboembolic complications that affect the patient's prognosis. COVID-19 vaccines significantly improve the prognosis for the course of the infection. The aim of this study was to evaluate the impacts of patient characteristics, including COVID-19 vaccinations, on perioperative mortality in acute coronary syndrome in Poland during the pandemic. We analyzed the data of 243,515 patients from the National Registry of Invasive Cardiology Procedures (Ogólnopolski Rejestr Procedur Kardiologii Inwazyjnej [ORPKI]). In this group, 7407 patients (21.74%) had COVID-19. The statistical analysis was based on a neural network that was verified by the random forest method. In 2020, the most significant impact on prognosis came from a diagnosis of unstable angina, a short period (<2 h) from pain occurrence to first medical contact, and a history of stroke. In 2021, the most significant factors were pre-hospital cardiac arrest, female sex, and a short period (<2 h) from first medical contact to coronary angiography. After adjusting for a six-week lag, a diagnosis of unstable angina and psoriasis were found to be relevant in the data from 2020, while in 2021, it was the time from the pain occurrence to the first medical contact (2−12 h) in non-ST segment elevation myocardial infarction and the time from first contact to balloon inflation (2−12 h) in ST-segment elevation myocardial infarction. The number of vaccinations was one of the least significant factors. COVID-19 vaccination does not directly affect perioperative prognosis in patients with acute coronary syndrome.

Individual and dyadic rope turning as a window into social coordination.

The spontaneous and intentional movement coordination between peoples is well understood. Less is known about such interactions when the coordination is subordinate to the task and when the task involves, next to vision, mechanically induced haptic and kinesthetic coupling between dyadic partners. We therefore investigated dyadic jump rope turning. Fifteen dyadic pairs conjointly turned a jump rope to which five markers were equidistantly attached, and whose movements were recorded in 3D. In addition, each participant turned one side of the rope while the other side was quasi-fixed in an individual baseline condition. The participants' goal was to turn the rope regularly and smoothly. Individual spontaneous turning frequencies differed substantially across participants. Yet, dyadic pairs spontaneously turned the rope at a common frequency, indicative of frequency entrainment. The dyadic rope rotations were less variable despite weaker between near-hand marker coordination than the individual rope rotations, and the degree of performance improvement was most pronounced for participants who were paired with a partner who performed better in the individual condition. The direction and relative strength of the coupling between partners varied substantially across dyads, but the degree of coupling asymmetry had no substantial effect on the rope tuning quality. The absolute degree in which dyadic partners adjusted to each other, however, scaled moderately with their turning performance. Although the individual performances did not predict the dyadic performances, the difference in individual performance between dyadic partners had some predictive value for the dyadic performance. In combination, these results indicate that the partners were functionally adapting to each other in order to satisfy the task goal and suggest that the relative performance differences rather than the individual performances has predictive value for conjoint action.
