BackgroundFaster time to reperfusion can be achieved by minimizing various patient and system-level delays that contribute to total ischemic time. Procedural delays within the catheterization laboratory represent a non-negligible and modifiable component in the chain of reperfusion, but remain unquantified by conventional metrics such as door-to-ballon (D2B) time. Universal catheter approaches have rapidly gained traction as an alternative to the traditional two catheter approach for transradial coronary interventions. However, their utility for both diagnostic angiography and subsequent angioplasty is limited, and the impact of this strategy on reperfusion outcomes has remained unexplored. We utilized a procedural metric termed fluoroscopy-to-device (FluTD) time to quantify the efficiency of a single catheter strategy, and assessed its impact on epicardial and myocardial perfusion.
Methods and resultsIn this retrospective study, consecutive STEMI patients undergoing transradial primary PCI (pPCI) at a tertiary care center in India between May 2022 to October 2024 were analyzed. Patients were divided into two groups: 51 underwent PCI using a single universal guiding catheter (UGC), and 51 underwent the conventional two-catheter (CTC) approach. The primary outcome of the study was a comparison of the FluTD time between the two procedural strategies. Secondary outcomes included myocardial blush grade (MBG), Thrombolysis in Myocardial Infarction (TIMI) flow grade, total fluoroscopy time, radiation dose, device safety and efficacy, and procedural success.The median FluTD time was significantly shorter in the UGC compared to the CTC group (3 minutes [IQR 3–4] vs. 10 minutes [IQR 8–17], p Conclusion
A single catheter strategy for both angiography and pPCI in STEMI patients was associated with a significant reduction in FluTD time and improved microvascular perfusion, without compromising device safety or efficacy. In low- and middle-income countries (LMICs), where intra- and extra-procedural delays are often more pronounced, inclusion of the single catheter strategy can optimize catheterization workflows and yield substantial cost-savings.
Dietary modification, particularly low-carbohydrate diet, and diabetes self-management education (DSME) have shown promise in improving glycaemic control among persons with type 2 diabetes mellitus (T2DM). However, real-world evidence from India is limited. This protocol describes the methods of a cluster randomised trial to determine the effectiveness and feasibility of adopting a low-carbohydrate diet among persons with T2DM.
Our cluster-randomised trial with a mixed-method process evaluation will use computer-generated block randomisation sequence to randomise Urban Primary Health Centres (UPHCs) (n=16) to either continue delivering the usual guideline-based care under the National Programme for Prevention and Control of Non-Communicable Diseases (NPNCD) or our study intervention. The study intervention will comprise a personalised nutrition counselling focusing on (i) low-carbohydrate diet (
We will include persons with T2DM, over the age of 30 years and above, irrespective of comorbidities, registered in the selected UPHC under care for diabetes for at least a month and with an glycated haemoglobin (HbA1c) level ≥6.5% during the screening test. We will collect data electronically using semistructured questionnaires and measure HbA1c, blood pressure, lipid profile, serum creatinine and body weight at baseline, 3, 6, 9 and 12 months after enrolment. We will use a difference in difference analysis, adjusted for clustering, to compare the change in HbA1c at the follow-up visits compared with baseline across the two study arms. We will conduct both intention-to-treat and per-protocol analysis, exploring reasons for differences in effect size.
The study protocol was reviewed and approved by the Scientific Advisory Committee/Institutional Human Ethics Committee of the research institution (NIE/IHEC/202302-03). The findings of this study will be disseminated through publication in peer-reviewed journals.
