Knowledge and Skills in Cardiopulmonary Resuscitation and Effect of Simulation Training on it among Healthcare Workers in a Tertiary Care Center in India.

Aim and background: High-quality cardiopulmonary resuscitation (CPR) is associated with improved patient outcomes, but healthcare workers (HCWs) may be frequently undertrained. This study aimed to assess baseline knowledge and skills among HCWs about basic and advanced life support and the effect of simulation-based training on it. Methods: It was a single-center prospective quasi-interventional study among resident doctors and nurses at a Tertiary Center in New Delhi, India. A questionnaire-based assessment was done to assess baseline knowledge. The participants then underwent simulation-based training followed by questionnaire-based knowledge assessment and skill assessment. A repeat questionnaire-based assessment was done 6 months post-training to assess knowledge retention. Results: A total of 82 HCWs (54 doctors and 28 nurses) were enrolled. The participants scored 22.28 ± 6.06 out of 35 (63.65%) in the pre-training knowledge assessment, with low scores in post-cardiac arrest care, advanced life support, and defibrillation. After the training, there was a significant rise in scores to 28.32 ± 4.08 out of 35 (80.9%) (p < 0.01). The retention of knowledge at 6 months was 68.87% (p < 0.01). The participants scored 92.61 ± 4.75% marks in skill assessment with lower scores in chest compressions and team leadership roles. There was a positive correlation (r = 0.35) between knowledge and skills scores (p < 0.01). Conclusion: There is a progressive decrease in baseline knowledge of HCWs with the further steps in the adult chain of survival. The simulation training program had a positive impact on the knowledge of HCWs. The training programs should focus on defibrillation, advanced life support, post-cardiac arrest care, and leadership roles.

Unveiling HPV's hidden link: Cardiovascular diseases and the viral intrigue.

Cardiovascular diseases (CVD) remain a major global health challenge, with an escalating impact on mortality despite advancements in managing conventional risk factors. This review investigates the intricate relationship between human papillomavirus (HPV) and CVD, shedding light on a novel aspect of cardiovascular health. Despite significant progress in understanding and managing traditional CVD risk factors, a substantial proportion of CVD cases lack these conventional markers. Recent research has unveiled HPV, a prevalent sexually transmitted infection, as a potential unconventional risk factor for CVD. This review delves into the underlying mechanisms linking HPV to CVD pathogenesis. HPV's influence on vascular endothelium and induction of systemic inflammation are key contributors. Additionally, HPV disrupts host lipid metabolism, further exacerbating the development of atherosclerosis. The link between HPV and CAD is not merely correlative; it encompasses a complex interplay of virological, immunological, and metabolic factors. Understanding the connection between HPV and CVD holds transformative potential. Insights from this review not only underscore the significance of considering HPV as a crucial risk factor but also advocate for targeted HPV screening and vaccination strategies to mitigate CVD risks. This multidisciplinary exploration bridges the gap between infectious diseases and cardiovascular health, emphasizing the need for a comprehensive approach to combating the global burden of cardiovascular disease. Further research and clinical guidelines in this realm are essential to harness the full scope of preventive and therapeutic interventions, ultimately shaping a healthier cardiovascular landscape.

Diagnostic Value of T1 Mapping in Detecting Iron Overload in Indian Patients with Thalassemia Major: A Comparison with T2* Mapping.

Purpose T2* is the gold standard for iron quantification in liver as well as myocardium. In this study, we evaluated the diagnostic accuracy of myocardial T1 mapping for the assessment of myocardial iron overload (MIO) as compared to the T2* mapping in patients with thalassemia major (TM). Methods Consecutive TM patients attending the thalassemia clinic were prospectively enrolled. Magnetic resonance imaging was performed on a 1.5 T scanner (Siemens Healthineers, Germany) using a gradient echo T2* as well as a T1 mapping (MOLLI) sequence done at a mid-ventricular short-axis single 8 mm slice of the left ventricle. Values were analyzed by manually drawing a region of interest in the mid-septum. T2*less than 20ms was used as the cutoff for significant MIO. Results One-hundred three patients (58 males, mean age: 17 ± 7.8 years, mean ferritin: 2009.5 µg/L) underwent cardiovascular magnetic resonance. Median T2* of myocardium was 33.45ms. Nineteen patients (18.4%) had T2*less than 20ms. T1 value was low (<850ms) in all the patients with T2* less than 20 ms. Receiver operating characteristic curve analysis revealed the best cutoff of native T1 mapping value as 850 ms which had high specificity (95.2%), sensitivity (94.2%) and negative predictive value (98.8%) for T2* less than 20ms. There was excellent agreement between T1 and T2* for diagnosis of MIO (Kappa-0.848, p <0.001). We did not find any patient who had normal T1 mapping values but had MIO on T2*. Conclusion T1 and T2* correlate well and normal T1 values may rule out presence of MIO. T1 mapping can act as additional imaging marker for MIO and may be helpful in centers with nonavailability or limited experience of T2*.

Distinguishing 'dual' from 'duplicated' right coronary artery: Revisiting the nomenclature.

We report a case of a 53-year-old man with a "short RCA" seen coursing within the proximal part of the right atrioventricular (AV) groove and terminating in the mid-portion of the right AV groove and a "long RCA" seen to have a proximal course outside the right AV groove, over the free wall of the right ventricle, where it gave rise to the right ventricular and acute marginal branches before returning to the right AV groove in its distal course. The discussion highlights the need for revisiting the nomenclature of "dual RCA and drawing a distinction between "dual" and "duplicated" RCA.

A unique location of the accessory pathway in a child with permanent junctional reciprocating tachycardia.

Permanent junctional reciprocating tachycardia (PJRT) is a rare supra ventricular tachycardia (SVT) due to an accessory pathway (AP), characterized by slow and decremental retrograde conduction, which is predominantly seen in infants and children. Although the typical site of AP in PJRT is a right posteroseptal region around or just within the coronary sinus (CS), atypical sites of AP have been described. We report a rare case of PJRT in a 7-year-old girl with an AP located in the superio-paraseptal (Para-Hsian) region that was successfully ablated through a non-coronary sinus.

Outcomes of out of hospital sudden cardiac arrest in India: A review and proposed reforms.

BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) is the cornerstone in managing out-of-hospital cardiac arrest (OHCA). However, India lacks a formal sudden cardiac arrest (SCA) registry and the infrastructure for a robust emergency medical services (EMS) response system. Also, there exists an opportunity to improve widespread health literacy and awareness regarding SCA. Other confounding variables, including religious, societal, and cultural sentiments hindering timely intervention, need to be considered for better SCA outcomes. OBJECTIVES: We highlight the current trends and practices of managing OHCA in India and lay the groundwork for improving the awareness, education, and infrastructure regarding the management of SCA. CONCLUSION: Effective management of OHCA in India needs collaborative grassroots reformation. Establishing a large-scale SCA registry and creating official and societal guidelines will be pivotal for transforming OHCA patient outcomes.

Low-dose ultra-high-pitch computed tomography coronary angiography: identifying the optimum combination of iteration strength and radiation dose reduction strategies to achieve true submillisievert scans

PURPOSE: To identify the optimum strength of advanced modeled iterative reconstruction (ADMIRE) to achieve the best subjective and objective image quality when combining three-dose reduction strategies, ultra-high-pitch computed tomography coronary angiography (FLASH CTCA; with single-dose ivabradine to lower heart rate), low tube voltage, and ADMIRE. METHODS: Sixty consecutive patients underwent FLASH CTCA at 100 kVp in this single-center prospective study. Single-dose ivabradine was administered to patients whose heart rate was above 75 bpm. Images were reconstructed using the three highest strengths of ADMIRE (A3, A4, and A5). Objective and subjective image quality (using a Likert scale) were evaluated in the three datasets. RESULTS: The signal strength remained unchanged but mean noise significantly reduced across the increasing strengths of ADMIRE [signal: 513.78 ± 101.7 Hounsfield units (HU) at A3, 515.6 ± 100.5 HU at A4, and 519.7 ± 107.9 HU at A5; noise: 23.4 ± 4.5 HU at A3, 20.2 ± 3.6 HU at A4, and 17.2 ± 3.3 HU at A5]. Signal-to-noise and contrast-to-noise ratios were the highest at A5, and A5 offered significantly higher Likert scores in image noise, vessel sharpness, and overall image quality than A3 or A4. Additionally, A5 did not interfere with image interpretation in any patient. CONCLUSION: Using all three dose reduction strategies during FLASH CTCA along with single-dose ivabradine administration ensures minimal radiation exposure in daily practice. In this study, A5 datasets had the best overall subjective and objective image quality despite their "plastic appearance". In the future, enhanced dose reduction can be obtained by further lowering tube voltages.

Comparing two different schedules of online learning for updated cardiopulmonary resuscitation guidelines in Covid-19 patients: A randomized study.

Background Coronavirus disease 2019 (Covid-19) is an evolving disease with newly generated evidence related to the clinical management of Covid-19 patients. We aimed to compare two online learning schedules for disseminating new cardiopulmonary resuscitation (CPR) guidelines in terms of knowledge gain and acceptability among nurses. Methods In a prospective randomized controlled study, 61 nurses trained in comprehensive cardiopulmonary life support (CCLS) were randomized to synchronous (n=31) and asynchronous learning groups (n= 30). The enhanced training module on CPR (ETMCPR) prepared by a team of experts was used to impart training to the nurses. Baseline data and pre-intervention knowledge of participants were collected using a structured demographic sheet and knowledge questionnaire (25 items) in a google form. Nurses in the synchronous group were provided training using ETMCPR through a licensed Zoom platform, while the nurses in the asynchronous group had access to the uploaded ETMCPR module in the e-learning platform. At the end of the intervention, the knowledge of the nurses was assessed along with their acceptability to the online learning schedule. Results Both schedules of online learning were effective in improving the knowledge scores of the nurses (11.93 [3.26] v. 21.15 [1.90], p=0.01 and 11.71 [3.12] v. 20.32 [1.71], p=0.01). The mean acceptability scores of nurses in the asynchronous group were statistically lower than in the synchronous group (38.93 [2.50] v. 42.5 [3.08], p=0.007). Conclusion Both synchronous and asynchronous schedules of online learning were effective in disseminating updated CPR guidelines; however, nurses in the synchronous group were more satisfied with the learning schedule.

1029 genomes of self-declared healthy individuals from India reveal prevalent and clinically relevant cardiac ion channelopathy variants.

BACKGROUND: The prevalence and genetic spectrum of cardiac channelopathies exhibit population-specific differences. We aimed to understand the spectrum of cardiac channelopathy-associated variations in India, which is characterised by a genetically diverse population and is largely understudied in the context of these disorders. RESULTS: We utilised the IndiGenomes dataset comprising 1029 whole genomes from self-declared healthy individuals as a template to filter variants in 36 genes known to cause cardiac channelopathies. Our analysis revealed 186,782 variants, of which we filtered 470 variants that were identified as possibly pathogenic (440 nonsynonymous, 30 high-confidence predicted loss of function ). About 26% (124 out of 470) of these variants were unique to the Indian population as they were not reported in the global population datasets and published literature. Classification of 470 variants by ACMG/AMP guidelines unveiled 13 pathogenic/likely pathogenic (P/LP) variants mapping to 19 out of the 1029 individuals. Further query of 53 probands in an independent cohort of cardiac channelopathy, using exome sequencing, revealed the presence of 3 out of the 13 P/LP variants. The identification of p.G179Sfs*62, p.R823W and c.420 + 2 T > C variants in KCNQ1, KCNH2 and CASQ2 genes, respectively, validate the significance of the P/LP variants in the context of clinical applicability as well as for large-scale population analysis. CONCLUSION: A compendium of ACMG/AMP classified cardiac channelopathy variants in 1029 self-declared healthy Indian population was created. A conservative genotypic prevalence was estimated to be 0.9-1.8% which poses a huge public health burden for a country with large population size like India. In the majority of cases, these disorders are manageable and the risk of sudden cardiac death can be alleviated by appropriate lifestyle modifications as well as treatment regimens/clinical interventions. Clinical utility of the obtained variants was demonstrated using a cardiac channelopathy patient cohort. Our study emphasises the need for large-scale population screening to identify at-risk individuals and take preventive measures. However, we suggest cautious clinical interpretation to be exercised by taking other cardiac channelopathy risk factors into account.

Impact of a nurse-led teleconsultation strategy for cardiovascular disease management during COVID-19 pandemic in India: a pyramid model feasibility study.

OBJECTIVE: The COVID-19 pandemic necessitated the use of telemedicine to maintain continuity of care for patients with cardiovascular diseases (CVDs). This study aimed to demonstrate the feasibility of implementing a nurse-led teleconsultation strategy for CVD management during the COVID-19 pandemic in India and evaluated the impact of nurse-led teleconsultations on patient treatment satisfaction. DESIGN, SETTING AND PARTICIPANTS: We developed a two-stage teleconsultation strategy and tested the feasibility of implementing a nurse-led teleconsultation strategy to manage CVD in a northern state (Punjab) in India. A multidisciplinary team of experts developed the treatment protocol used for teleconsultations to manage CVD. Nurses were trained to provide teleconsultation, triaging of patients and referrals to the physicians. Patients with CVD who had an outpatient visit or hospitalisation between September 2019 and March 2020 at the Dayanand Medical College Hospital, Ludhiana, India, were contacted by phone and offered teleconsultations. Telemedicine strategy comprised: stage 1 nurse-led teleconsultations and stage 2 physician-led teleconsultations. Descriptive analysis was performed to report the proportion of patients triaged by the two-stage telemedicine strategy, and patient's clinical characteristics, and treatment satisfaction between the nurse-led versus physician-led teleconsultations. RESULTS: Overall, nurse-led stage 1 teleconsultations were provided to 12 042 patients with CVD. The mean (SD) age of the participants was 58.9 years (12.8), and men were 65.4%. A relatively small proportion of patients (6.3%) were referred for the stage-2 physician-led teleconsultations and of these only 8.4% required hospitalisations. During stage 1 nurse-led teleconsultations, patients were referred to the physicians due to uncontrolled diabetes (24.9%), uncontrolled hypertension (18.7%) and congestive heart failure (16.2%). The patient's treatment satisfaction was similar between the nurse-led versus physician-led teleconsultations (p=0.07). CONCLUSION: This study showed that a nurse-led telemedicine strategy is feasible to implement in a resource-constraint setting for triaging patients with CVD and reduces physician's burden.

Early repolarization syndrome, epilepsy, and atrial fibrillation in a young girl with novel KCND3 mutation managed with quinidine.

A 6-year-old girl presented with a difficult to control epilepsy syndrome. On evaluation, additional presyncope episodes associated with polymorphic ventricular tachycardia were also noted. A diagnosis of early repolarization syndrome (ERS) was made with an early repolarization pattern on electrocardiogram, documented VT episodes, and clinical presyncope (proposed Shanghai score 7). Paroxysmal atrial fibrillation (AF) was also noted on 24-h Holter recordings. The child was stabilized with isoprenaline infusion and was later discharged with arrhythmia control on quinidine and cilostazol. The genetic evaluation revealed a potassium channel KCND3 gene missense mutation. The case highlights the association of epilepsy syndrome and AF with ERS; the possible association of KCND3 gene mutation with a malignant phenotype; and management issues in a small child.

Association of Low-Dose Triple Combination Therapy vs Usual Care With Time at Target Blood Pressure: A Secondary Analysis of the TRIUMPH Randomized Clinical Trial.

Importance: Cumulative exposure to high blood pressure (BP) is an adverse prognostic marker. Assessments of BP control over time, such as time at target, have been developed but assessments of the effects of BP-lowering interventions on such measures are lacking. Objective: To evaluate whether low-dose triple combination antihypertensive therapy was associated with greater rates of time at target compared with usual care. Design, Setting, and Participants: The Triple Pill vs Usual Care Management for Patients With Mild-to-Moderate Hypertension (TRIUMPH) trial was a open-label randomized clinical trial of low-dose triple BP therapy vs usual care conducted in urban hospital clinics in Sri Lanka from February 2016 to May 2017. Adults with hypertension (systolic BP >140 mm Hg and/or diastolic BP >90 mm Hg or in patients with diabetes or chronic kidney disease, systolic BP >130 mm Hg and/or diastolic BP >80 mm Hg) requiring initiation (untreated patients) or escalation (patients receiving monotherapy) of antihypertensive therapy were included. Patients were excluded if they were currently taking 2 or more blood pressure-lowering drugs or had severe or uncontrolled blood pressure, accelerated hypertension or physician-determined need for slower titration of treatment, a contraindication to the triple combination pill therapy, an unstable medical condition, or clinically significant laboratory values deemed by researchers to be unsuitable for the study. All 700 individuals in the original trial were included in the secondary analysis. This post hoc analysis was conducted from December 2020 to December 2021. Intervention: Once-daily fixed-dose triple combination pill (telmisartan 20 mg, amlodipine 2.5 mg, and chlorthalidone 12.5 mg) therapy vs usual care. Main Outcomes and Measures: Between-group differences in time at target were compared over 24 weeks of follow-up, with time at target defined as percentage of time at target BP. Results: There were a total of 700 randomized patients (mean [SD] age, 56 [11] years; 403 [57.6%] women). Patients allocated to the triple pill group (n = 349) had higher time at target compared with those in the usual care group (n = 351) over 24 weeks' follow-up (64% vs 43%; risk difference, 21%; 95% CI, 16-26; P < .001). Almost twice as many patients receiving triple pill therapy achieved more than 50% time at target during follow-up (64% vs 37%; P < .001). The association of the triple pill with an increase in time at target was seen early, with most patients achieving more than 50% time at target by 12 weeks. Those receiving the triple pill achieved a consistently higher time at target at all follow-up periods compared with those receiving usual care (mean [SD]: 0-6 weeks, 36.3% [30.9%] vs 21.7% [28.9%]; P < .001; 6-12 weeks, 55.2% [31.9%] vs 33.7% [33.0%]; P < .001; 12-24 weeks, 66.0% [31.1%] vs 43.5% [34.3%]; P < .001). Conclusions and Relevance: To our knowledge, this analysis provides the first estimate of time at target as an outcome assessing longitudinal BP control in a randomized clinical trial. Among patients with mild to moderate hypertension, treatment with a low-dose triple combination pill was associated with substantially higher time at target compared with usual care.

Long-term outcome after thoracoscopic cardiac sympathectomy for refractory ventricular tachyarrhythmia storm.

A man in his 40s presented with an acute anterior wall myocardial infarction (MI) 6 hours after symptom onset to a non-percutaneous intervention enabled hospital and underwent thrombolysis with tenecteplase. His chest pain resolved post-thrombolysis although ST segment resolution was less than 50%. He had an episode of sustained ventricular tachycardia (VT) 48 hours after MI which was successfully cardioverted with 150 J biphasic shock. A month later he presented with a ventricular tachycardia storm that was refractory to pharmacological management. He underwent radiofrequency ablation of the VT using three-dimensional mapping. Although the patient remained free of VT/ventricular fibrillation (VF) for 48 hours, he had an episode of VF subsequently. A decision for bilateral surgical video assisted thoracoscopic cardiac sympathetic denervation was taken and the patient remained free of ventricular tachyarrhythmias after the procedure until.

Role of endothelial colony forming cells (ECFCs) Tetrahydrobiopterin (BH4) in determining ECFCs functionality in coronary artery disease (CAD) patients.

Nitric oxide (NO.) is critical for functionality of endothelial colony forming cells (ECFCs). Dimerization of endothelial nitric oxide synthase (eNOS) is must to produce NO. and tetrahydrobiopterin (BH4) plays a crucial role in stabilizing this state. We investigated BH4 level in ECFCs and its effect on ECFCs functionality in CAD patients. Intracellular biopterin levels and ECFCs functionality in terms of cell viability, adhesion, proliferation, in vitro wound healing and angiogenesis were assessed. Guanosine Triphosphate Cyclohydrolase-1 (GTPCH-1) expression was studied in ECFCs. Serum total reactive oxygen/nitrogen species was measured and effect of nitrosative stress on ECFC's biopterins level and functionality were evaluated by treating with 3-morpholino sydnonimine (SIN-1). BH4 level was significantly lower in ECFCs from CAD patients. Cell proliferation, wound closure reflecting cellular migration as well as in vitro angiogenesis were impaired in ECFCs from CAD patients. Wound healing capacity and angiogenesis were positively correlated with ECFC's BH4. A negative effect of nitrosative stress on biopterins level and cell functionality was observed in SIN-1 treated ECFCs. ECFCs from CAD exhibited impaired functionality and lower BH4 level. Association of BH4 with wound healing capacity and angiogenesis suggest its role in maintaining ECFC's functionality. Oxidative stress may be a determinant of intracellular biopterin levels.

Effect of Yoga on Clinical Outcomes and Quality of Life in Patients With Vasovagal Syncope (LIVE-Yoga).

OBJECTIVES: This study aims to determine the impact of yoga as an adjunct to standard therapy versus standard therapy alone on the symptomatic burden in patients with recurrent vasovagal syncope (VVS). BACKGROUND: There is a significant reduction in the quality of life (QoL) of patients with recurrent VVS. Existing management therapies have been largely ineffective. Recent trials have demonstrated the efficacy of yoga in diseases with autonomic imbalance, suggesting its possible utility in VVS. METHODS: Patients with recurrent VVS were randomized to receive either a specialized yoga training program in addition to current guideline-based therapy (intervention arm, group 1) or current guideline-based therapy alone (control arm, group 2). The primary outcome was a composite of the number of episodes of syncope and presyncope at 12 months. Secondary outcomes included QoL assessment by World Health Organization Quality of Life Brief Field questionnaire (WHOQoL-BREF) scores and Syncope Functional Status Questionnaire scores at 12 months, head up tilt test, and heart rate variability at 6 weeks. RESULTS: A total of 55 patients underwent randomization. The mean number of syncopal or presyncopal events at 12 months was 0.7 ± 0.7 in the intervention arm compared to 2.52 ± 1.93 in the control arm (P < 0.01). In the intervention arm, 13 (43.3%) patients remained free of events versus 4 (16.0%) patients in the control arm (P = 0.02). QoL at 12 months showed significant improvement of all Syncope Functional Status Questionnaire scores and 2 domains of WHOQoL-BREF scores (P < 0.05). CONCLUSIONS: Yoga as adjunctive therapy is superior to standard therapy alone in reducing the symptomatic burden and improving QoL in patients with recurrent VVS.

Changing pattern of admissions for acute myocardial infarction in India during the COVID-19 pandemic.

AIM: Studies on the changes in the presentation and management of acute myocardial infarction (AMI) during the COVID-19 pandemic from low- and middle-income countries are limited. We sought to determine the changes in the number of admissions, management practices, and outcomes of AMI during the pandemic period in India. METHODS & RESULTS: In this two-timepoint cross-sectional study involving 187 hospitals across India, patients admitted with AMI between 15th March to 15th June in 2020 were compared with those admitted during the corresponding period of 2019. We included 41,832 consecutive adults with AMI. Admissions during the pandemic period (n = 16414) decreased by 35·4% as compared to the corresponding period in 2019 (n = 25418). We observed significant heterogeneity in this decline across India. The weekly average decrease in AMI admissions in 2020 correlated negatively with the number of COVID cases (r = -0·48; r2 = 0·2), but strongly correlated with the stringency of lockdown index (r = 0·95; r2 = 0·90). On a multi-level logistic regression, admissions were lower in 2020 with older age categories, tier 1 cities, and centers with high patient volume. Adjusted utilization rate of coronary angiography, and percutaneous coronary intervention decreased by 11·3%, and 5·9% respectively. CONCLUSIONS: The magnitude of reduction in AMI admissions across India was not uniform. The nature, time course, and the patient demographics were different compared to reports from other countries, suggesting a significant impact due to the lockdown. These findings have important implications in managing AMI during the pandemic.

World Heart Federation Roadmap on Atrial Fibrillation - A 2020 Update.

The World Heart Federation (WHF) commenced a Roadmap initiative in 2015 to reduce the global burden of cardiovascular disease and resultant burgeoning of healthcare costs. Roadmaps provide a blueprint for implementation of priority solutions for the principal cardiovascular diseases leading to death and disability. Atrial fibrillation (AF) is one of these conditions and is an increasing problem due to ageing of the world's population and an increase in cardiovascular risk factors that predispose to AF. The goal of the AF roadmap was to provide guidance on priority interventions that are feasible in multiple countries, and to identify roadblocks and potential strategies to overcome them. Since publication of the AF Roadmap in 2017, there have been many technological advances including devices and artificial intelligence for identification and prediction of unknown AF, better methods to achieve rhythm control, and widespread uptake of smartphones and apps that could facilitate new approaches to healthcare delivery and increasing community AF awareness. In addition, the World Health Organisation added the non-vitamin K antagonist oral anticoagulants (NOACs) to the Essential Medicines List, making it possible to increase advocacy for their widespread adoption as therapy to prevent stroke. These advances motivated the WHF to commission a 2020 AF Roadmap update. Three years after the original Roadmap publication, the identified barriers and solutions were judged still relevant, and progress has been slow. This 2020 Roadmap update reviews the significant changes since 2017 and identifies priority areas for achieving the goals of reducing death and disability related to AF, particularly targeted at low-middle income countries. These include advocacy to increase appreciation of the scope of the problem; plugging gaps in guideline management and prevention through physician education, increasing patient health literacy, and novel ways to increase access to integrated healthcare including mHealth and digital transformations; and greater emphasis on achieving practical solutions to national and regional entrenched barriers. Despite the advances reviewed in this update, the task will not be easy, but the health rewards of implementing solutions that are both innovative and practical will be great.

Exploring Barriers to Medication Adherence Using COM-B Model of Behaviour Among Patients with Cardiovascular Diseases in Low- and Middle-Income Countries: A Qualitative Study.

INTRODUCTION: In 2016, cardiovascular diseases (CVDs) led to 17.9 million deaths worldwide, representing 31% of all global deaths. CVDs are the leading cause of mortality worldwide and significant barriers to achieving the sustainable development goals. Modern medicines have been significant in improving health outcomes. However, non-adherence to medication is one of the reasons behind adverse health-related outcomes among patients suffering from atherosclerotic cardiovascular disease in low- and middle-income countries. PATIENTS AND METHODS: This qualitative study was conducted at two tertiary care hospitals in India and Ghana. A total of 35 in-depth interviews were conducted with atherosclerosis cardiovascular disease (ASCVD) patients. The data were analysed thematically using the Capability Opportunity and Motivation (COM-B) framework. FINDINGS: The findings were summarised under three important broad themes of the COM-B framework: capability, opportunity and behaviour. Under capability, comprehension of disease, medication schedule, and unplanned travel affected adherence among patients. Cost of medication, insurance and access were the critical factors under opportunity, which negatively influenced medication adherence. Mood, beliefs about treatment and outcome expectations under motivation led to non-adherence among patients. Apart from these factors, some important health system factors such as health care experience and trust in the facilities and reliance on alternative medication also affected adherence in both countries. CONCLUSION: This study has highlighted that the health system factors have dominantly influenced adherence to medication in India and Ghana. In India, we found participants to be satisfied with their health care provided at the government hospitals. However, limited time for consultation, lack of well-stocked pharmacy and unclear prescription negatively influenced adherence among participants in India and Ghana. The study emphasises that the health system needs to be strengthened, and the patients' belief system needs to be explored to address the issue of medication adherence in LMICs.

Utility of Caudal Angulation for Venous Access under Fluoroscopic Guidance during Cardiovascular Implantable Electronic Device Implantation.

BACKGROUND: Axillary venous access is preferred for CIED implantation. The procedure is usually performed under fluoroscopic guidance in anteroposterior (A-P) view. However, there is a lack of perception of depth in this view with a fear of creating complications. Caudal fluoroscopy (adding 30°-35° caudal angulation to A-P projection) has been proposed to circumvent this problem. OBJECTIVE: The aim of this study was to elucidate the advantages of caudal fluoroscopy using fluoroscopic images, contrast venograms, and CT angiography images of axillary vein. METHODS: The fluoroscopic images and contrast venograms obtained in the A-P view were compared with caudal fluoroscopy in patients undergoing CIED implantation at our centre. Also, the CT angiography images of axillary vein were reconstructed to understand the relative anatomy of the vein and the underlying lung parenchyma, simulating these 2 projections. RESULTS: The CT angiography images, contrast venograms, and fluoroscopic images confirmed that caudal fluoroscopy allows better visualization of the vein in relation to the lung parenchyma and rib cage. Analysis of fluoroscopic images revealed that the bend of the first rib formed a conical prominence in caudal fluoroscopy. This served as an important bony landmark for successful venous access, which was usually obtained while the needle was being directed towards this prominence in caudal fluoroscopy. CONCLUSIONS: The proposed advantages of caudal fluoroscopy for CIED implantation have been elucidated by analysis of CT angiography images, contrast venograms, and fluoroscopic images.
