Cook CM, Howard JP, Ahmad Y, et al., 2021, Comparing invasive hemodynamic responses in adenosine hyperemia versus physical exercise stress in chronic coronary syndromes., Int J Cardiol
OBJECTIVES: Adenosine hyperemia is an integral component of the physiological assessment of obstructive coronary artery disease in patients with chronic coronary syndrome (CCS). The aim of this study was to compare systemic, coronary and microcirculatory hemodynamics between intravenous (IV) adenosine hyperemia versus physical exercise stress in patients with CCS and coronary stenosis. METHODS: Twenty-three patients (mean age, 60.6 ± 8.1 years) with CCS and single-vessel coronary stenosis underwent cardiac catheterization. Continuous trans-stenotic coronary pressure-flow measurements were performed during: i) IV adenosine hyperemia, and ii) physical exercise using a catheter-table-mounted supine ergometer. Systemic, coronary and microcirculatory hemodynamic responses were compared between IV adenosine and exercise stimuli. RESULTS: Mean stenosis diameter was 74.6% ± 10.4. Median (interquartile range) FFR was 0.54 (0.44-0.72). At adenosine hyperemia versus exercise stress, mean aortic pressure (Pa, 91 ± 16 mmHg vs 99 ± 15 mmHg, p < 0.0001), distal coronary pressure (Pd, 58 ± 21 mmHg vs 69 ± 24 mmHg, p < 0.0001), trans-stenotic pressure ratio (Pd/Pa, 0.63 ± 0.18 vs 0.69 ± 0.19, p < 0.0001), microvascular resistance (MR, 2.9 ± 2.2 mmHg.cm-1.sec-1 vs 4.2 ± 1.7 mmHg.cm-1.sec-1, p = 0.001), heart rate (HR, 80 ± 15 bpm vs 85 ± 21 bpm, p = 0.02) and rate-pressure product (RPP, 7522 ± 2335 vs 9077 ± 3200, p = 0.0001) were all lower. Conversely, coronary flow velocity (APV, 23.7 ± 9.5 cm/s vs 18.5 ± 6.8 cm/s, p = 0.02) was higher. Additionally, temporal changes in Pa, Pd, Pd/Pa
Seligman H, Nijjer S, van de Hoef TP, et al., 2021, Phasic Flow Patterns of Right versus Left Coronary Arteries in Patients Undergoing Clinical Physiological Assessment., EuroIntervention
BACKGROUND: Coronary blood flow in humans is known to be predominantly diastolic. Small studies in animals and humans suggest this is less pronounced or even reversed in the right coronary artery. AIMS: This study aims to characterise the phasic patterns of coronary flow in the left versus right coronary arteries of patients undergoing invasive physiological assessment. METHODS: We analysed data from the Iberian-Dutch-English Collaborators (IDEAL) Study. 482 simultaneous pressure and flow measurements from 301 patients were included in our analysis. RESULTS: On average, coronary flow was higher in diastole both at rest and during hyperaemia both in the RCA and LCA (mean diastolic-to-systolic velocity ratio was, respectively, 1.85±0.70, 1.76±0.58, 1.53±0.34 and 1.58±0.43 for LCArest , LCAhyp , RCArest and RCAhyp , p<0.001 for between vessel comparisons). Although the type of RCA dominance affected the DSVR magnitude (RCAdom = 1.55 ± 0.35, RCAco-dom =1.40 ± 0.27, RCAnon-dom = 1.35, (SD not reported as n=3), systolic flow was very rarely predominant (DSVR was greater than or equal to 1.00 in 472/482 cases (97.9%) overall), with equal prevalence in the LCA. Stenosis severity or microvascular dysfunction had negligible impact on DSVR in both RCA and LCA (DSVR x hyperaemic stenosis resistance R 2 = 0.018, p=0.03 and DSVR x coronary flow reserve R 2 <0.001, p=0.98). CONCLUSIONS: In patients with CAD undergoing physiological assessment, diastolic flow predominance is seen in both left and right coronary arteries. Clinical interpretation of coronary physiological data should therefore not differ between the left and the right coronary systems.
Levy S, Cole G, Pabari P, et al., 2021, New horizons in cardiogeriatrics: geriatricians and heart failure care-the custard in the tart, not the icing on the cake., Age Ageing, Vol: 50, Pages: 1064-1068
Heart failure (HF) can be considered a disease of older people. It is a leading cause of hospitalisation and is associated with high rates of morbidity and mortality in the over-65s. In 2012, an editorial in this journal detailed the latest HF research and guidelines, calling for greater integration of geriatricians in HF care. This current article reflects upon what has been achieved in this field in recent years, highlighting some future challenges and promising areas. It is written from the perspective of one such integrated team and explores the new role of cardiogeriatrician, working in a multidisciplinary team to deliver and improve care to increasingly complex, older, frail patients with multiple comorbidities who present with primary cardiology problems, especially decompensated HF. Geriatric liaison has improved the care of frail patients in orthopaedics, cancer services, stroke, acute medicine and numerous community settings. We propose that this vital role should now be extended to cardiology teams in general and to HF in particular.

INTRODUCTION: The ORBITA trial of percutaneous coronary intervention (PCI) versus a placebo procedure for patients with stable angina was conducted across six sites in the United Kingdom via home monitoring and telephone consultations. Patients underwent detailed assessment of medication adherence which allowed us to measure the efficacy of the implementation of the optimization protocol and interpretation of the main trial endpoints. METHODS: Prescribing data were collected throughout the trial. Self-reported adherence was assessed, and urine samples collected at pre-randomization and at follow-up for direct assessment of adherence using high-performance liquid chromatography with tandem mass spectrometry (HPLC MS/MS). RESULTS: Self-reported adherence was >96% for all drugs in both treatment groups at both stages. The percentage of samples in which drug was detected at pre-randomization and at follow-up in the PCI versus placebo groups respectively was: clopidogrel, 96% versus 90% and 98% versus 94%; atorvastatin, 95% versus 92% and 92% versus 91%; perindopril, 95% versus 97% and 85% versus 100%; bisoprolol, 98% versus 99% and 96% versus 97%; amlodipine, 99% versus 99% and 94% versus 96%; nicorandil, 98% versus 96% and 94% versus 92%; ivabradine, 100% versus 100% and 100% versus 100%; and ranolazine, 100% versus 100% and 100% versus 100%. CONCLUSIONS: Adherence levels were high throughout the study when quantified by self-reporting methods and similarly high proportions of drug were detected by urinary assay. The results indicate successful implementation of the optimization protocol delivered by telephone, an approach that could serve as a model for treatment of chronic conditions, particularly as consultations are increasingly conducted online.

Coronavirus disease 2019 (COVID-19) is forcing cardiology departments to rapidly adapt existing clinical guidelines to a new reality and this is especially the case for acute coronary syndrome pathways. In this focused review, the authors discuss how COVID-19 is affecting acute cardiology care and propose pragmatic guideline modifications for the diagnosis and management of acute coronary syndrome patients, particularly around the appropriateness of invasive strategies as well as length of hospital stay. The authors also discuss the use of personal protective equipment for healthcare workers in cardiology. Based on shared global experiences and growing peer-reviewed literature, it is possible to put in place modified acute coronary syndrome treatment pathways to offer safe pragmatic decisions to patients and staff.

Kaura A, Sterne J, Trickey A, et al., 2020, Invasive versus non-invasive management of elderly patients with non-ST elevation myocardial infarction: cohort study based on routine clinical data, The Lancet, Vol: 396, Pages: 623-634, ISSN: 0140-6736
BackgroundPrevious trials suggest lower long-term mortality after invasive rather than non-invasive management among patients with non-ST elevation myocardial infarction (NSTEMI), but these excluded very elderly patients.MethodsWe estimated the effect of invasive versus non-invasive management within 3 days of peak troponin on survival in NSTEMI patients aged ≥80 years, using routine clinical data collected during 2010–2017 (NIHR Health Informatics Collaborative). Propensity scores based on pre-treatment variables were derived using logistic regression; patients with high probabilities of non-invasive or invasive management were excluded. Patients who died within 3 days without receiving invasive management were assigned to the invasive or non-invasive management groups based on their propensity scores, to mitigate immortal time bias. We estimated mortality hazard ratios comparing invasive with non-invasive management, and also compared rates of hospital admission for heart failure.FindingsOf 1976 patients with NSTEMI, 101 died within 3 days of their peak troponin, whilst 375 were excluded because of extreme propensity scores. The remaining 1500 patients (56% non-invasive management) had a median age 86 (IQR 82-89) years. During median follow-up of 3.0 (IQR 1.2-4.8) years, there were 613 (41%) deaths. Using inverse probability weighting, adjusted cumulative 5-year mortality was 36% and 55% in the invasive and non-invasive management groups, respectively. The mortality hazard ratio comparing invasive with non-invasive management was 0.64 (95% CI 0.52-0.79) after multivariable adjustment for clinical characteristics and propensity score and inclusion of patients who died within three days. Invasive management was associated with lower incidence of hospital admissions for heart failure (adjusted rate ratio compared with non-invasive management 0.67, 95% CI 0.48–0.93).
Hughes AD, Park C, Ramakrishnan A, et al., 2020, Feasibility of estimation of aortic wave intensity using non-invasive pressure recordings in the absence of flow velocity in man, Frontiers in Physiology, Vol: 11, Pages: 1-9, ISSN: 1664-042X
Background: Wave intensity analysis provides valuable information on ventriculo-arterial function, hemodynamics, and energy transfer in the arterial circulation. Widespread use of wave intensity analysis is limited by the need for concurrent measurement of pressure and flow waveforms. We describe a method that can estimate wave intensity patterns using only non-invasive pressure waveforms (pWIA).Methods: Radial artery pressure and left ventricular outflow tract (LVOT) flow velocity waveforms were recorded in 12 participants in the Southall and Brent Revisited (SABRE) study. Pressure waveforms were analyzed using custom-written software to derive the excess pressure (Pxs) which was scaled to peak LVOT velocity and used to calculate wave intensity. These data were compared with wave intensity calculated using the measured LVOT flow velocity waveform. In a separate study, repeat measures of pWIA were performed on 34 individuals who attended two clinic visits at an interval of ≈1 month to assess reproducibility and reliability of the method.Results: Pxs waveforms were similar in shape to aortic flow velocity waveforms and the time of peak Pxs and peak aortic velocity agreed closely. Wave intensity estimated using pWIA showed acceptable agreement with estimates using LVOT velocity tracings and estimates of wave intensity were similar to values reported previously in the literature. The method showed fair to good reproducibility for most parameters.Conclusion: The Pxs is a surrogate of LVOT flow velocity which, when appropriately scaled, allows estimation of aortic wave intensity with acceptable reproducibility. This may enable wider application of wave intensity analysis to large studies.
Kaura A, Arnold AD, Vasileios P, et al., 2020, Prognostic significance of troponin level in 3,121 patients presenting with atrial fibrillation (The NIHR Health Informatics Collaborative TROP-AF study), Journal of the American Heart Association, Vol: 9, ISSN: 2047-9980
Background-—Patients presenting with atrial fibrillation (AF) often undergo a blood test to measure troponin, but interpretation of theresult is impeded by uncertainty about its clinical importance. We investigated the relationship between troponin level, coronaryangiography, and all-cause mortality in real-world patients presenting with AF.Methods and Results-—We used National Institute of Health Research Health Informatics Collaborative data to identify patients admitted between 2010 and 2017 at 5 tertiary centers in the United Kingdom with a primary diagnosis of AF. Peak troponin results 7 were scaled as multiples of the upper limit of normal. A total of 3121 patients were included in the analysis. Over a median followup of 1462 (interquartile range, 929–1975) days, there were 586 deaths (18.8%). The adjusted hazard ratio for mortality associatedwith a positive troponin (value above upper limit of normal) was 1.20 (95% CI, 1.01–1.43; P<0.05). Higher troponin levels were associated with higher risk of mortality, reaching a maximum hazard ratio of 2.6 (95% CI, 1.9–3.4) at 250 multiples of the upper limit of normal. There was an exponential relationship between higher troponin levels and increased odds of coronary angiography.The mortality risk was 36% lower in patients undergoing coronary angiography than in those who did not (adjusted hazard ratio, 0.61; 95% CI, 0.42–0.89; P=0.01).Conclusions-—Increased troponin was associated with increased risk of mortality in patients presenting with AF. The lower hazard ratio in patients undergoing invasive management raises the possibility that the clinical importance of troponin release in AF may be mediated by coronary artery disease, which may be responsive to revascularization.

Howard JP, Tan J, Shun-Shin MJ, et al., 2020, Improving ultrasound video classification: an evaluation of novel deep learning methods in echocardiography., J Med Artif Intell, Vol: 3
Echocardiography is the commonest medical ultrasound examination, but automated interpretation is challenging and hinges on correct recognition of the 'view' (imaging plane and orientation). Current state-of-the-art methods for identifying the view computationally involve 2-dimensional convolutional neural networks (CNNs), but these merely classify individual frames of a video in isolation, and ignore information describing the movement of structures throughout the cardiac cycle. Here we explore the efficacy of novel CNN architectures, including time-distributed networks and two-stream networks, which are inspired by advances in human action recognition. We demonstrate that these new architectures more than halve the error rate of traditional CNNs from 8.1% to 3.9%. These advances in accuracy may be due to these networks' ability to track the movement of specific structures such as heart valves throughout the cardiac cycle. Finally, we show the accuracies of these new state-of-the-art networks are approaching expert agreement (3.6% discordance), with a similar pattern of discordance between views.

Ahmad Y, Vendrik J, Eftekhari A, et al., 2019, Determining the Predominant Lesion in Patients With Severe Aortic Stenosis and Coronary Stenoses: A Multicenter Study Using Intracoronary Pressure and Flow, Circulation: Cardiovascular Interventions, Vol: 12, ISSN: 1941-7640
Background:Patients with severe aortic stenosis (AS) often have coronary artery disease. Both the aortic valve and the coronary disease influence the blood flow to the myocardium and its ability to respond to stress; leading to exertional symptoms. In this study, we aim to quantify the effect of severe AS on the coronary microcirculation and determine if this is influenced by any concomitant coronary disease. We then compare this to the effect of coronary stenoses on the coronary microcirculation.Methods:Group 1: 55 patients with severe AS and intermediate coronary stenoses treated with transcatheter aortic valve implantation (TAVI) were included. Group 2: 85 patients with intermediate coronary stenoses and no AS treated with percutaneous coronary intervention were included. Coronary pressure and flow were measured at rest and during hyperemia in both groups, before and after TAVI (group 1) and before and after percutaneous coronary intervention (group 2).Results:Microvascular resistance over the wave-free period of diastole increased significantly post-TAVI (pre-TAVI, 2.71±1.4 mm Hg·cm·s−1 versus post-TAVI 3.04±1.6 mm Hg·cm·s−1 [P=0.03]). Microvascular reserve over the wave-free period of diastole significantly improved post-TAVI (pre-TAVI 1.88±1.0 versus post-TAVI 2.09±0.8 [P=0.003]); this was independent of the severity of the underlying coronary stenosis. The change in microvascular resistance post-TAVI was equivalent to that produced by stenting a coronary lesion with an instantaneous wave-free ratio of ≤0.74.Conclusions:TAVI improves microcirculatory function regardless of the severity of underlying coronary disease. TAVI for severe AS produces a coronary hemodynamic improvement equivalent to the hemodynamic benefit of stenting coronary stenoses with instantaneous wave-free ratio values <0.74. Future trials of physiology-guided revascularization in severe AS may consider us

ObjectiveTo determine the relation between age and troponinlevel and its prognostic implication.DesignRetrospective cohort study.SettingFive cardiovascular centres in the UK National Institutefor Health Research Health Informatics Collaborative(UK-NIHR HIC).Participants257948 consecutive patients undergoing troponintesting for any clinical reason between 2010 and2017.Main outcome measureAll cause mortality.Results257948 patients had troponin measured during thestudy period. Analyses on troponin were performedusing the peak troponin level, which was the highesttroponin level measured during the patient’s hospitalstay. Troponin levels were standardised as a multipleof each laboratory’s 99th centile of the upper limitof normal (ULN). During a median follow-up of 1198days (interquartile range 514-1866 days), 55850(21.7%) deaths occurred. A positive troponin result(that is, higher than the upper limit of normal)signified an overall 3.2-fold higher mortality hazard(95% confidence interval 3.1-fold to 3.2-fold) overthree years. The mortality hazard varied markedly withage, from 10.6-fold (8.5-fold to 13.3-fold) in 18-29year olds to 1.5 (1.4 to 1.6) in those older than 90.A positive troponin result was associated with anapproximately 15 percentage points higher absolutethree year mortality across all age groups. The excessmortality with a positive troponin result was heavilyconcentrated in the first few weeks. Results wereanalysed using multivariable adjusted restrictedcubic spline Cox regression. A direct relation wasseen between troponin level and mortality in patientswithout acute coronary syndrome (ACS, n=120049),whereas an inverted U shaped relation was foundin patients with ACS (n=14468), with a paradoxicaldecline in mortality at peak troponin levels >70xULN.In the group with ACS, the inverted U shaped relationpersisted after multivariable adjustment in those whowere managed invasively; however, a direct positiverelation was found between troponin level
Al-Lamee R, Shun-Shin M, Howard J, et al., 2019, Dobutamine stress echocardiography ischemia as a predictor of the placebo-controlled efficacy of percutaneous coronary intervention in stable coronary artery disease: the stress echo-stratified analysis of ORBITA, Circulation, Vol: 140, Pages: 1971-1980, ISSN: 0009-7322
BackgroundDobutamine stress echocardiography (DSE) is widely used to test for ischemia in patients with stable coronary artery disease (CAD). In this analysis we studied the ability of pre-randomization stress echo score to predict the placebo-controlled efficacy of percutaneous coronary intervention (PCI) within the ORBITA trial. MethodsOne hundred and eighty-three patients underwent DSE before randomization. The stress echo score is broadly the number of segments abnormal at peak stress, with akinetic segments counting double and dyskinetic segments counting triple. The ability of pre-randomization stress echo to predict the placebo-controlled effect of PCI on response variables was tested using regression modelling.ResultsAt pre-randomization, the stress echo score was 1.561.77 in the PCI arm (n=98) and 1.611.73 in the placebo arm (n=85). There was a detectable interaction between pre-randomization stress echo score and the effect of PCI on angina frequency score with a larger placebo-controlled effect in patients with the highest stress echo score (pinteraction=0.031). With our sample size we were unable to detect an interaction between stress echo score and any other patient-reported response variables: freedom from angina (pinteraction=0.116), physical limitation (pinteraction=0.461), quality of life (pinteraction=0.689), EQ-5D-5L quality of life score (pinteraction=0.789) or between stress echo score and physician-assessed Canadian Cardiovascular Society angina class (pinteraction=0.693), and treadmill exercise time (pinteraction=0.426). ConclusionsThe degree of ischemia assessed by DSE predicts the placebo-controlled efficacy of PCI on patient-reported angina frequency. The greater the downstream stress echo abnormality caused by a stenosis, the greater the reduction in symptoms from PCI.
