Waiting time is inevitable during cardiovascular (CV) care. This study examines whether waiting room-based CV education could complement CV care.
A 2:1 randomised clinical trial of patients in ...waiting rooms of hospital cardiology clinics. Intervention participants received a series of tablet-delivered CV educational videos and were randomised 1:1 to receive another video on cardiopulmonary resuscitation (CPR) or no extra video. Control received usual care. The primary outcome was the proportion of participants reporting high motivation to improve CV risk-modifying behaviours (physical activity, diet and blood pressure monitoring) post-clinic.
clinic satisfaction, CV lifestyle risk factors (RFs) and confidence to perform CPR. Assessors were blinded to treatment allocation.
Among 514 screened, 330 were randomised (n=220 intervention, n=110 control) between December 2018 and March 2020, mean age 53.8 (SD 15.2), 55.2% male. Post-clinic, more intervention participants reported high motivation to improve CV risk-modifying behaviours: 29.6% (64/216) versus 18.7% (20/107), relative risk (RR) 1.63 (95% CI 1.04 to 2.55). Intervention participants reported higher clinic satisfaction RR: 2.19 (95% CI 1.45 to 3.33). Participants that received the CPR video (n=110) reported greater confidence to perform CPR, RR 1.61 (95% CI 1.20 to 2.16). Overall, the proportion of participants reporting optimal CV RFs increased between baseline and 30-day follow-up (16.1% vs 24.8%, OR=2.44 (95% CI 1.38 to 4.49)), but there was no significant between-group difference at 30 days.
CV education delivery in the waiting room is a scalable concept and may be beneficial to CV care. Larger studies could explore its impact on clinical outcomes.

Background
The provision of reliable patient education is essential for shared decision-making. However, many clinicians are reluctant to use commonly available resources, as they are generic and may ...contain information of insufficient quality. Clinician-created educational materials, accessed during the waiting time prior to consultation, can potentially benefit clinical practice if developed in a time- and resource-efficient manner.
Objective
The aim of this study is to evaluate the utility of educational videos in improving patient decision-making, as well as consultation satisfaction and anxiety, within the outpatient management of chronic disease (represented by atrial fibrillation). The approach involves clinicians creating audiovisual patient education in a time- and resource-efficient manner for opportunistic delivery, using mobile smart devices with internet access, during waiting time before consultation.
Methods
We implemented this educational approach in outpatient clinics and collected patient responses through an electronic survey. The educational module was a web-based combination of 4 short videos viewed sequentially, followed by a patient experience survey using 5-point Likert scales and 0-100 visual analogue scales. The clinician developed the audiovisual module over a 2-day span while performing usual clinical tasks, using existing hardware and software resources (laptop and tablet). Patients presenting for the outpatient management of atrial fibrillation accessed the module during waiting time before their consultation using either a URL or Quick Response (QR) code on a provided tablet or their own mobile smart devices. The primary outcome of the study was the module’s utility in improving patient decision-making ability, as measured on a 0-100 visual analogue scale. Secondary outcomes were the level of patient satisfaction with the videos, measured with 5-point Likert scales, in addition to the patient’s value for clinician narration and the module’s utility in improving anxiety and long-term treatment adherence, as represented on 0-100 visual analogue scales.
Results
This study enrolled 116 patients presenting for the outpatient management of atrial fibrillation. The proportion of responses that were “very satisfied” with the educational video content across the 4 videos ranged from 93% (86/92) to 96.3% (104/108) and this was between 98% (90/92) and 99.1% (107/108) for “satisfied” or “very satisfied.” There were no reports of dissatisfaction for the first 3 videos, and only 1% (1/92) of responders reported dissatisfaction for the fourth video. The median reported scores (on 0-100 visual analogue scales) were 90 (IQR 82.5-97) for improving patient decision-making, 89 (IQR 81-95) for reducing consultation anxiety, 90 (IQR 81-97) for improving treatment adherence, and 82 (IQR 70-90) for the clinician’s narration adding benefit to the patient experience.
Conclusions
Clinician-created educational videos for chronic disease management resulted in improvements in patient-reported informed decision-making ability and expected long-term treatment adherence, as well as anxiety reduction. This form of patient education was also time efficient as it used the sunk time cost of waiting time to provide education without requiring additional clinician input.
Periodontitis is a chronic inflammatory disorder often seen in patients with diabetes mellitus (DM). Individuals with diabetes are at a greater risk of developing cardiovascular complications and ...this may be related, in part, to lipid abnormalities observed in these individuals. The objective of this systematic review is to compile the current scientific evidence of the effects of periodontal treatment on lipid profiles in patients with type 2 diabetes mellitus. Through a systematic search using MEDLINE, EMBASE, PubMed, and Web of Science, 313 articles were identified. Of these, seven clinical trials which met all inclusion criteria were chosen for analysis. Between baseline and 3-month follow-up, there was a statistically significant reduction in the levels of total cholesterol (mean differences (MD) -0.47 mmol/L (95% confidence interval (CI), -0.75, -0.18,
= 0.001)), triglycerides (MD -0.20 mmol/L (95% CI -0.24, -0.16,
< 0.00001)) favouring the intervention arm, and a statistically significant reduction in levels of high density lipoprotein (HDL) (MD 0.06 mmol/L (95% CI 0.03, 0.08,
< 0.00001)) favouring the control arm. No significant differences were observed between baseline and 6-month follow-up levels for any lipid analysed. The heterogeneity between studies was high. This review foreshadows a potential benefit of periodontal therapy for lipid profiles in patients suffering from type 2 DM, however, well designed clinical trials using lipid profiles as primary outcome measures are warranted.
Background The clinical relevance of minor elevations of cardiac troponin (cTn) in the general population remains uncertain. The objective of this systematic review was to examine the literature and ...evaluate the prevalence of raised cTn in asymptomatic, community populations and explore the strength of the relationship between cTn and cardiovascular mortality amongst those studied. Methods Studies were identified by searching Medline, Embase, CINAHL, EBM Reviews, Cochrane Library and using the “related citation” search tool in PubMed from inception through August 2014. Prospective cohort studies of asymptomatic individuals recruited from the community (age ≥ 18 years) that assessed the relationship between cTn levels and mortality or cardiovascular events were included. Results Twenty-one prospective studies involving 64,855 participants were identified. An elevated cTn measurement (>99th percentile) occurred in 5% of individuals and was associated with a tripling of risk of mortality (adjusted RR 3.07, 95% confidence interval CI 2.32-4.06) and cardiovascular mortality (adjusted RR 3.30, 95% CI 1.77-6.12). In studies including high sensitivity assays, cTn was detectable in 58% of individuals. A detectable cardiac troponin T (cTnT) was also associated with an increased risk of cardiovascular mortality (adjusted RR 1.32, 95% CI 1.10 – 1.59). The risk increased with increasing cTnT level. Conclusions Elevated troponin in asymptomatic individuals in the community is associated with a tripling of risk of all-cause and cardiovascular mortality. Cardiac troponin T (cTnT) is generally not measured in this group of patients, but may potentially have utility in predicting risk in this population. Further research is required to assess if this risk is modifiable with usual primary prevention treatments.
Treatment inertia is a recognised barrier to blood pressure control, and simpler, more effective treatment strategies are needed. We hypothesised that a hypertension management strategy starting with ...a single pill containing ultra-low-dose quadruple combination therapy would be more effective than a strategy of starting with monotherapy.
QUARTET was a multicentre, double-blind, parallel-group, randomised, phase 3 trial among Australian adults (≥18 years) with hypertension, who were untreated or receiving monotherapy. Participants were randomly assigned to either treatment, that started with the quadpill (containing irbesartan at 37·5 mg, amlodipine at 1·25 mg, indapamide at 0·625 mg, and bisoprolol at 2·5 mg) or an indistinguishable monotherapy control (irbesartan 150 mg). If blood pressure was not at target, additional medications could be added in both groups, starting with amlodipine at 5 mg. Participants were randomly assigned using an online central randomisation service. There was a 1:1 allocation, stratified by site. Allocation was masked to all participants and study team members (including investigators and those assessing outcomes) except the manufacturer of the investigational product and one unmasked statistician. The primary outcome was difference in unattended office systolic blood pressure at 12 weeks. Secondary outcomes included blood pressure control (standard office blood pressure <140/90 mm Hg), safety, and tolerability. A subgroup continued randomly assigned allocation to 12 months to assess long-term effects. Analyses were per intention to treat. This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry, ACTRN12616001144404, and is now complete.
From June 8, 2017, to Aug 31, 2020, 591 participants were recruited, with 743 assessed for eligibility, 152 ineligible or declined, 300 participants randomly assigned to intervention of initial quadpill treatment, and 291 to control of initial standard dose monotherapy treatment. The mean age of the 591 participants was 59 years (SD 12); 356 (60%) were male and 235 (40%) were female; 483 (82%) were White, 70 (12%) were Asian, and 38 (6%) reported as other ethnicity; and baseline mean unattended office blood pressure was 141 mm Hg (SD 13)/85 mm Hg (SD 10). By 12 weeks, 44 (15%) of 300 participants had additional blood pressure medications in the intervention group compared with 115 (40%) of 291 participants in the control group. Systolic blood pressure was lower by 6·9 mm Hg (95% CI 4·9–8·9; p<0·0001) and blood pressure control rates were higher in the intervention group (76%) versus control group (58%; relative risk RR 1·30, 95% CI 1·15–1·47; p<0·0001). There was no difference in adverse event-related treatment withdrawals at 12 weeks (intervention 4·0% vs control 2·4%; p=0·27). Among the 417 patients who continued, uptitration occurred more frequently among control participants than intervention participants (p<0·0001). However, at 52 weeks mean unattended systolic blood pressure remained lower by 7·7 mm Hg (95% CI 5·2–10·3) and blood pressure control rates higher in the intervention group (81%) versus control group (62%; RR 1·32, 95% CI 1·16–1·50). In all randomly assigned participants up to 12 weeks, there were seven (3%) serious adverse events in the intervention group and three (1%) serious adverse events in the control group.
A strategy with early treatment of a fixed-dose quadruple quarter-dose combination achieved and maintained greater blood pressure lowering compared with the common strategy of starting monotherapy. This trial demonstrated the efficacy, tolerability, and simplicity of a quadpill-based strategy.

Summary
Chest pain is the second most common reason for adult emergency department presentations.
Most patients have low or intermediate risk chest pain, which historically has led to inpatient ...admission for further evaluation.
Rapid access chest pain clinics represent an innovative outpatient pathway for these low and intermediate risk patients, and have been shown to be safe and reduce hospital costs.
Despite variations in rapid access chest pain clinic models, there are limited data to determine the most effective approach. Developing a national framework could be beneficial to provide sites with evidence, possible models, and business cases. Multicentre data analysis could enhance understanding and monitoring of the service.
To examine whether there are sex differences in the characteristics, management, and clinical outcomes of patients with an ST-elevation myocardial infarction (STEMI). Design, setting: Cohort study; ...analysis of data collected prospectively by the CONCORDANCE acute coronary syndrome registry from 41 Australian hospitals between February 2009 and May 2016.
2898 patients (2183 men, 715 women) with STEMI.
Rates of revascularisation (percutaneous coronary intervention PCI, thrombolysis, coronary artery bypass grafting CABG), adjusted for GRACE risk score quartile.
timely vascularisation rates; major adverse cardiac event rates; clinical outcomes and preventive treatments at discharge.
The mean age of women with STEMI at presentation was 66.6 years (SD, 14.5 years), of men, 60.5 years (SD, 12.5 years). The proportions of women with hypertension, diabetes, prior stroke, chronic kidney disease, chronic heart failure, or dementia were larger than those of men; fewer women had histories of previous coronary artery disease or myocardial infarction, or of prior PCI or CABG. Women were less likely to have undergone coronary angiography (odds ratio, adjusted for GRACE score quartile aOR, 0.53; 95% CI, 0.41-0.69) or revascularisation (aOR, 0.42; 95% CI, 0.34-0.52); they were less likely to have received timely revascularisation (aOR, 0.72; 95% CI, 0.63-0.83) or primary PCI (aOR, 0.76; 95% CI, 0.61-0.95). Six months after admission, the rates of major adverse cardiovascular events (aOR, 2.68; 95% CI, 1.76-4.09) and mortality (aOR, 2.17; 95% CI, 1.24-3.80) were higher for women. At discharge, significantly fewer women than men received β-blockers, statins, and referrals to cardiac rehabilitation.
Women with STEMI are less likely to receive invasive management, revascularisation, or preventive medication at discharge. The reasons for these persistent differences in care require investigation.
A healthy diet is an important component of secondary prevention of coronary heart disease (CHD). The TEXT ME study was a randomised clinical trial of people with CHD that were randomised into ...standard care or a text-message programme in addition to standard care. This analysis aimed to: 1) assess the effects of the intervention onadherence to the dietary guideline recommendations; 2) assess the consistency of effect across sub-groups; and 3) assess whether adherence to the dietary guideline recommendations mediated the improvements in objective clinical outcomes.
Dietary data were collected using a self-report questionnaire to evaluate adherence to eight dietary guideline recommendations in Australia, including consumption of vegetables, fruits, fish, type of fat used for cooking and in spreads, takeaway food, salt and standard alcohol drinks. The primary outcome of this analysis was the proportion of patients adhering to ≥ 4 dietary guideline recommendations concomitantly and each recommendation was assessed individually as secondary outcomes. Data were analysed using log-binomial regression for categorical variables and analysis of covariance for continuous variables.
Among 710 patients, 54% were adhering to ≥ 4 dietary guideline recommendations (intervention 53% vs control 56%, p = 0.376) at baseline. At six months, the intervention group had a significantly higher proportion of patients adhering to ≥ 4 recommendations (314, 93%) compared to the control group (264, 75%, RR 1.23, 95% CI 1.15-1.31, p < 0.001). In addition, the intervention patients reported consuming higher amounts of vegetables, fruits, and fish per week; less takeaway foods per week; and greater salt intake control. The intervention had a similar effect in all sub-groups tested. There were significant mediational effects of the increase in adherence to the recommendations for the association between the intervention and LDL-cholesterol (p < 0.001) and body mass index (BMI) at six months follow-up (p = 0.005).
A lifestyle-focused text-message programme improved adherence to the dietary guideline recommendations, and specifically improved self-reported consumption of vegetables, fruits, fish, takeaway foods and salt intake. Importantly, these improvements partially mediated improvements in LDL-cholesterol and BMI. This simple and scalable text-messaging intervention could be used as a strategy to improve diet in people with CHD.

This study explored factors that may influence blood pressure (BP) control in patients with atrial fibrillation (AF) with hypertension.
Cross-sectional retrospective analysis of the MedicineInsight ...database which includes de-identified electronic health records from general practices (GPs) across Australia. BP control was assessed in patients with diagnosed AF and hypertension (controlled BP defined as <140/90 mm Hg). We explored BP control, factors influencing BP control and likelihood of receiving guideline-recommended treatment.
34 815 patients with AF and hypertension were included; mean age was 76.9 (10.2 SD) years and 46.2% were female. 38.0% had uncontrolled BP. Women (OR 0.72; 95% CI 0.68, 0.76; p<0.001) and adults ≥75 years (OR 0.78; 95% CI 0.70, 0.86; p<0.001) were less likely to have controlled BP. Greater continuity of care (CoC; that is, visits with the same clinician) and having frequent GP visits were associated with higher odds of controlled BP (model 1: CoC, OR 1.29; 95% CI 1.20, 1.40, p<0.001; GP visits, OR 1.71; 95% CI 1.58, 1.85, p<0.001) and a greater likelihood of being prescribed ≥2 types of BP-lowering medicines (model 2: CoC, OR 1.12; 95% CI 1.03, 1.23; p=0.011; GP visits, OR 1.80; 95% CI 1.63, 1.98; p<0.001).
Uncontrolled BP was more likely in women and adults ≥75 years. Patients who had frequent GP visits with the same clinician were more likely to have BP controlled and receive guideline-recommended antihypertensive treatment. This suggests that targeting these primary care factors could potentially improve BP control and subsequently reduce stroke risk in patients with AF.
Inequitable access to health services influences health outcomes. Some studies have found patients of lower socio-economic status (SES) wait longer for surgery, but little data exist on access to ...outpatient services. This study analyzed patient-level data from outpatient public cardiology clinics and assessed whether low SES patients spend longer accessing ambulatory services. Retrospective analysis of cardiology clinic encounters across 3 public hospitals between 2014 and 2019 was undertaken. Data were linked to age, gender, Indigenous status, country of birth, language spoken at home, number of comorbidities, and postcode. A cox proportional hazards model was applied adjusting for visit type (new/follow up), clinic, and referral source. Higher hazard ratio (HR) indicates shorter clinic time. Overall, 22 367 patients were included (mean SD age 61.4 15.2, 14 925 (66.7%) male). Only 7823 (35.0%) were born in Australia and 8452 (37.8%) were in the lowest SES quintile. Median total clinic time was 84 min (IQR 58-130). Visit type, clinic, and referral source were associated with clinic time (R2 = 0.23, 0.35, 0.20). After adjusting for these variables, older patients spent longer in clinic (HR 0.94 0.90-0.97), though there was no difference according to SES (HR 1.02 0.99-1.06) or other variables of interest. Time spent attending an outpatient clinic is substantial, amplifying an already significant time burden faced by patients with chronic health conditions. SES was not associated with longer clinic time in our analysis. Time spent in clinics could be used more productively to optimize care, improve health outcomes and patient experience.
