Background Recent data suggest that colchicine may reduce cardiovascular events among patients presenting with acute coronary syndromes. This sub-study of the Australian COPS trial aimed to assess whether colchicine affects health status outcomes. Methods Health status was assessed at baseline and 12-months using the EuroQol-5 Dimension 5-level (EQ-5D-5L) score and the full 19-question Seattle Angina Questionnaire (SAQ). Data were available for 786 patients (388 randomized to colchicine, 398 to placebo). Results Baseline characteristics were well matched between groups; mean age was 60.1 (SD 14.8) years, and 20% were female. Baseline health status scores were impaired, and most parameters demonstrated significant improvement from baseline to 12-months (EQ-5D-5L Visual Analogue Score [VAS] 69.3 to 77.7; SAQ angina frequency score 83.0 to 95.3, both p Conclusions Treatment with colchicine did not appear to affect change in measures of health status following acute coronary syndromes, but it did lead to a greater likelihood of improvement in physical limitation scores.

Accurate measurement of central blood pressure (BP) using upper arm cuff-based methods is associated with several factors, including determining the level of systolic BP (SBP) amplification. This study aimed to determine the agreement between cuff-based and invasively measured SBP amplification. Patients undergoing coronary angiography had invasive SBP amplification (brachial SBP – central SBP) measured simultaneously with cuff-based SBP amplification using a commercially available central BP device (device 1: Sphygmocor Xcel; n = 171, 70% men, 60 ± 10 years) and a now superseded model of a central BP device (device 2: Uscom BP+; n = 52, 83% men, 62 ± 10 years). Mean difference (±2SD, limits of agreement) between cuff-based and invasive SBP amplification was 4 mmHg (−12, +20 mmHg, P < 0.001) for device 1 and −2 mmHg (−14, +10 mmHg, P = 0.10) for device 2. Both devices systematically overestimated SBP amplification at lower levels and underestimated at higher levels of invasive SBP amplification, but with stronger bias for device 1 (r = −0.68 vs. r = −0.52; Z = 2.72; P = 0.008). Concordance of cuff-based and invasive SBP amplification across quartiles of invasive SBP amplification was low, particularly in the lowest and highest quartiles. The root mean square errors from regression between cuff-based central SBP and brachial SBP were significantly lower (indicating less variability) than from invasive regression models (P < 0.001). Irrespective of the difference from invasive measurements, cuff-based estimates of SBP amplification showed evidence of proportional systematic bias and had less individual variability. These observations could provide insights on how to improve the performance of cuff-based central BP.

To assess the safety, feasibility and independent predictors of next day discharge (NDD) in patients undergoing minimalist transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) in a real-world Australian population.This single centre study reviewed 135 consecutive patients who underwent minimalist transfemoral TAVI from June 2020 to February 2022. Baseline demographics, procedural characteristic and outcomes were obtained. All patients were assessed by the local protocol for NDD. Patients were then divided into two groups: those who achieved next day discharge (NDD) and those requiring1 overnight hospital stay. Univariate, bivariate and stepwise multivariate logistic regression modelling was used to identify the predictors of successful next day discharge.The mean age of the cohort was 82.9±5.7 years with 62.3% patients male, the average STS score was 4.1±2.4. All 135 patients underwent a successful transfemoral TAVI procedure, with 131 (97%) receiving a balloon-expandable valve. Ninety-seven (97) (71.9%) patients achieved NDD. Thirty (30)-day outcomes were excellent with a 30-day mortality of 0.7%, transient ischaemic attack/cardiovascular accident (TIA/CVA) 1.5%, major vascular complication 1.5% and 11.4% need for permanent pacemaker (PPM). In patients not achieving NDD, the average length of stay (LOS) was 3.0 days. Baseline characteristics demonstrated pre-existing first degree atrioventricular (AV) block and right bundle branch block (RBBB) as statistically significant negative predictors of NDD on univariate analysis. Next day discharge was achievable in only 50% of patients who suffered any minor or major procedural complication (15/30). Stepwise multivariate logistic regression modelling demonstrated female gender (OR 3.094, 95% CI 1.141-8.391, p=0.026), smaller aortic valve area (AVA) (OR 48.265, 95% CI 2.269-102.6, p=0.013), the presence of diabetes mellitus (OR 0.594, 95% CI 0.356-0.991, p=0.046) and a longer procedure time (OR 0.960, 95% CI 0.935-0.986, p=0.002) as statistically significant negative predictors of NDD. In addition, there was no difference in 30-day readmission rates between the NDD and non-NDD cohort (7.2% vs 10.5%, p=0.386).Next day discharge is safe and feasible in almost three quarters of patients undergoing minimalist TAVI for severe AS in a predominantly balloon expandable valve cohort, with a very low rate of 30-day readmission. NDD provides advantages for hospital efficiency and improved cost-effectiveness. Female gender, smaller AVA, the presence of diabetes mellitus and a longer procedure time were independent negative predictors of successful NDD.

Objective: The soluble guanylate cyclase stimulator riociguat is approved for the treatment of adult patients with pulmonary arterial hypertension (PAH) and inoperable or persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH) following Phase 3 randomized trials. The EXPosurE Registry RiociguaT in patients with pulmonary hypertension (EXPERT) study was designed to monitor the long-term safety of riociguat in clinical practice. Methods: EXPERT was an international, multicenter, prospective, uncontrolled, non-interventional cohort study of patients treated with riociguat. Patients were followed for at least 1 year and up to 4 years from enrollment or until 30 days after stopping riociguat treatment. Primary safety outcomes were adverse events (AEs) and serious adverse events (SAEs) coded using Medical Dictionary for Regulatory Activities preferred terms and System Organ Classes version 21.0, collected during routine clinic visits and collated via case report forms. Results: In total, 956 patients with CTEPH were included in the analysis. The most common AEs in these patients were peripheral edema/edema (11.7%), dizziness (7.5%), right ventricular (RV)/cardiac failure (7.7%), and pneumonia (5.0%). The most common SAEs were RV/cardiac failure (7.4%), pneumonia (4.1%), dyspnea (3.6%), and syncope (2.5%). Exposure-adjusted rates of hemoptysis/pulmonary hemorrhage and hypotension were low and comparable to those in the long-term extension study of riociguat (Chronic Thromboembolic Pulmonary Hypertension Soluble Guanylate Cyclase–Stimulator Trial [CHEST-2]). Conclusion: Data from EXPERT show that in patients with CTEPH, the safety of riociguat in routine practice was consistent with the known safety profile of the drug, and no new safety concerns were identified. © 2020 The Authors Eli Lilly and Company; Pfizer; Bayer; GlaxoSmithKline; Merck; Actelion Pharmaceuticals; Meso Scale Diagnostics; United Therapeutics Corporation; Novartis Pharma; Merck Sharp and Dohme; GlaxoSmithKline Australia; Deutsche Forschungsgemeinschaft; Grupo Ferrer Internacional, S.A The EXPERT registry was funded by Bayer AG (Berlin, Germany) and Merck Sharp & Dohme Corp., a subsidiary of Merck & Co.

Background: Inflammation plays a crucial role in clinical manifestations and complications of acute coronary syndromes (ACS). Colchicine, a commonly used treatment for gout, has recently emerged as a novel therapeutic option in cardiovascular medicine owing to its anti-inflammatory properties. We sought to determine the potential usefulness of colchicine treatment in patients with ACS. Methods: This was a multicenter, randomized, double-blind, placebo-controlled trial involving 17 hospitals in Australia that provide acute cardiac care service. Eligible participants were adults (18–85 years) who presented with ACS and had evidence of coronary artery disease on coronary angiography managed with either percutaneous coronary intervention or medical therapy. Patients were assigned to receive either colchicine (0.5 mg twice daily for the first month, then 0.5 mg daily for 11 months) or placebo, in addition to standard secondary prevention pharmacotherapy, and were followed up for a minimum of 12 months. The primary outcome was a composite of all-cause mortality, ACS, ischemia-driven (unplanned) urgent revascularization, and noncardioembolic ischemic stroke in a time to event analysis. Results: A total of 795 patients were recruited between December 2015 and September 2018 (mean age, 59.8±10.3 years; 21% female), with 396 assigned to the colchicine group and 399 to the placebo group. Over the 12-month follow-up, there were 24 events in the colchicine group compared with 38 events in the placebo group ( P =0.09, log-rank). There was a higher rate of total death (8 versus 1; P =0.017, log-rank) and, in particular, noncardiovascular death in the colchicine group (5 versus 0; P =0.024, log-rank). The rates of reported adverse effects were not different (colchicine 23.0% versus placebo 24.3%), and they were predominantly gastrointestinal symptoms (colchicine, 23.0% versus placebo, 20.8%). Conclusions: The addition of colchicine to standard medical therapy did not significantly affect cardiovascular outcomes at 12 months in patients with ACS and was associated with a higher rate of mortality.

We describe the case of a degenerative, sutureless bioprosthetic valve (BPV) with deformation and stent infolding in a patient with elevated surgical risk. Following discussion among the heart team, balloon valve fracture was performed to facilitate deployment of an aortic valve-in-valve transcatheter heart valve. Post-procedural imaging demonstrated BPV frame protrusion and contained annular rupture, which required operative intervention.

Pulmonary arterial hypertension (PAH) is a rare disease with a poor prognosis if not treated. Pharmacological treatment options for PAH have increased significantly over the past 10 years, with availability of intravenous, oral and inhaled drugs targeting the nitric oxide, endothelin and prostacyclin pathways. Treatment with these therapies in specialised pulmonary hypertension centres has resulted in reductions in patient symptoms, disease progression and mortality, and improved exercise capacity. Recognition of chronic thromboembolic pulmonary hypertension is important, as this cause of pulmonary hypertension may be amenable to surgical treatment. Several new oral drugs, including macitentan, riociguat and selexipag, some of which have novel modes of action, and the use of combinations of PAH drugs have recently been shown to be beneficial in treating PAH and are likely to change treatment for this condition in the future.

Background Thrombocytosis and inflammation are vital elements in the pathogenesis of atherosclerosis. The platelet-to-lymphocyte ratio (PLR) is a novel biomarker that combines these parameters and has been shown to be associated with cardiovascular disease (CVD). This study aimed to determine whether PLR correlates with coronary artery disease (CAD) in high-risk patients, and if the relationship is affected by age. Methods Consecutive patients referred for coronary angiogram were evaluated (n = 822). with 608 patients demonstrating CAD, compared to 214 patients with normal coronary arteries. Patients were stratified into premature CAD (age < 55) and non-premature CAD (age ≥ 55). High and low PLR groups were defined as admission PLR in the highest (≥ 146.7) and lower two tertiles ( < 146.7) respectively. Multivariate logistic regression was undertaken to adjust for traditional cardiovascular risk factors. Results In univariate analysis, high PLR negatively correlated with premature CAD (OR 0.45, 95%CI 0.23–0.87, P = 0.017), while its association with CAD in older patients did not reach statistical significance (OR 1.32, 95%CI 0.89–1.97, P = 0.170). After adjustment for traditional risk factors, high PLR was significantly associated with increased CAD in older patients (OR 2.22, 95%CI 1.28–3.82, P = 0.004) but decreased premature CAD (OR 0.31, 95%CI 0.11–0.87, P = 0.026). Conclusions There is an age-related effect on the correlation between PLR and CAD. While high PLR was an independent marker of CAD in older high-risk patients, it was negatively correlated with premature CAD in younger patients. PLR is widely available and inexpensive, and could be used in highlighting patients at high risk for CAD.

Introduction: It is well known that high density lipoprotein cholesterol is inversely correlated with the risk of coronary artery disease. However, data is limited regarding the relationship of high density lipoprotein cholesterol in the acute setting of coronary artery disease and particularly how it compares to the most well-known biomarker, cardiac troponin I. Hypothesis: We assessed the hypothesis that high density lipoprotein cholesterol could be used as an alternative marker to troponin for acute coronary syndrome (ACS) in high risk patients. Methods: We analysed 740 patients of the BRAVEHEART cohort presenting for coronary angiography at our institution between October 2009 and March 2014. Of these, 153 patients presented with ACS, including 44 with ST elevation myocardial infarction and 109 with non-ST elevation myocardial infarction, and 587 patients presented without ACS. Binary logistic regression was used to compare high density lipoprotein cholesterol and cardiac troponin I levels as predictors of ACS, independent of age, sex, cardiac risk factors and statin use. Results: Patients presenting with ACS had higher median cardiac troponin I levels (0.34 vs. 0.02 μg/L; p Conclusion: In conclusion, high density lipoprotein cholesterol was found to be an independent marker of ACS in high risk patients at our institution. Further studies on high density lipoprotein cholesterol could determine its clinical use in conjunction with troponin levels in patients presenting with ACS.
