Methods Patients with recurrent and first-episode IE enrolled in the EUROpean ENDOcarditis (EURO-ENDO) registry including 156 centres were identified and compared using propensity score matching. Recurrent IE was classified as relapse when IE occurred ≤6 months after a previous episode or reinfection when IE occurred >6 months after the prior episode. Results 3106 patients were enrolled: 2839 (91.4%) patients with first-episode IE (mean age 59.4 (±18.1); 68.3% male) and 267 (8.6%) patients with recurrent IE (mean age 58.1 (±17.7); 74.9% male). Among patients with recurrent IE, 13.2% were intravenous drug users (IVDUs), 66.4% had a repaired or replaced valve with the tricuspid valve being more frequently involved compared with patients with first-episode IE (20.3% vs 14.1%; p=0.012). In patients with a first episode of IE, the aortic valve was more frequently involved (45.6% vs 39.5%; p=0.061). Recurrent relapse and reinfection were 20.6% and 79.4%, respectively. Staphylococcus aureus was the microorganism most frequently observed in both groups (p=0.207). There were no differences in in-hospital and post-hospitalisation mortality between recurrent and first-episode IE. In patients with recurrent IE, in-hospital mortality was higher in IVDU patients. Independent predictors of poorer in-hospital and 1-year outcome, including the occurrence of cardiogenic and septic shock, valvular disease severity and failure to undertake surgery when indicated, were similar for recurrent and first-episode IE. Conclusions In-hospital and 1-year mortality was similar in patients with recurrent and first-episode IE who shared similar predictors of poor outcome.","PeriodicalId":9311,"journal":{"name":"British Heart Journal","volume":"108 1","pages":"1729 - 1736"},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49278776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute AR requires prompt intervention yet often is missed because the clinical presentation is not recognised. The large volume of retrograde diastolic flow into a left ventricle (LV) without compensatory dilation results in an abrupt decrease in cardiac output and increase in LV enddiastolic pressure (figure 1).

The IHM is likely due to vasa vasorum rupture with or without an intimal tear. As the IMH expands, it compresses the ipsilateral coronary artery wall against the contralateral wall, thereby occluding the coronary lumen and results in ischaemia or infarction of the subtended myocardium. While much has been learnt about the clinical presentation and sequelae of SCAD from studies of retrospective and ambispective registries, metaanalyses and prospective cohorts, major gaps in our understanding of disease mechanisms, management and outcomes persist, with little prospective data from large cohorts and lack of data from randomised control studies. GarciaGuimaraes and colleagues report on the treatment and clinical outcomes of SCAD determined in a cohort of 389 patients assembled from The Spanish Registry on SCAD involving subjects from 34 hospitals. Although the study uses a nonrandomised observational design, particular strengths are its prospective nature, the reasonably large size of the cohort assembled, its careful documentation of SCAD diagnosis by a central angiography reading group and the use of an independent clinical events committee to evaluate adverse outcomes. Moreover, although the study has limitations, as duly acknowledged by the authors, and sheds little new light on the optimal management of SCAD, it does yield important new hypothesisgenerating findings that warranted confirmation in future controlled studies. The study confirms that for those patients who survive to hospital admission, the overall prognosis is favourable, with a survival at discharge of 98%, and 6% suffering a major inhospital adverse cardiovascular event (MAE), mainly driven by reinfarction or unplanned revascularisation and 13% developing a major adverse cardiovascular or cerebrovascular event (MACCE) over a median followup of 2 years. Of course, the outcomes of SCAD sufferers prior to hospitalisation remains unknown, and undoubtedly, some succumb to the disorder. Although the inhospital outcomes reported by GarciaGuimaraes et al are confirmatory, if not better than those reported by others, the MAEs and MACCEs reported did not include the considerable psychosocial burden associated with SCAD, including insomnia, anxiet","PeriodicalId":9311,"journal":{"name":"British Heart Journal","volume":"108 1","pages":"1506 - 1507"},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46720459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latter is of particular importance when considering the development of patient symptoms, adverse clinical events and the need for aortic valve replacement (AVR). The hypertrophic response of the left ventricle is protective for many years, even decades, yet with time it decompensates and patients transition to heart failure. Current wisdom is that valve replacement should be performed in patients with severe stenosis just as that decompensation is starting to occur. Most commonly we use symptom development as our barometer of developing myocardial ill health, however there is increasing interest in more objective markers of LV dysfunction with which to optimise the timing of AVR. These include imaging markers of myocardial fibrosis and early systolic dysfunction as well as serum biomarkers such as highsensitivity troponin and Nterminalprobeta natriuretic peptide (NTproBNP)). 6 It is on this background that Dr Tan and colleagues report a multibiomarker study in 173 patients (55% male, age 69±11 years) with moderatetosevere AS, preserved LV function and New York Heart Association (NYHA) class III symptoms. A range of widely used (highsensitivity troponin T, NTproBNP) and novel (growth differentiation factor, suppression of tumorigenicity2, midregional proadrenomedullin (MRproADM), and MRproatrial natriuretic peptide) biomarkers were obtained from each participant, who were then followed up for a median of 2.7 years. The primary outcome was a composite of allcause mortality, progression to NYHA class IIIIV, and heart failure hospitalisation with the secondary outcome also incorporating syncope and acute coronary syndromes. Impressively, all but one participant had followup data available until either (1) aortic valve replacement was performed, (2) the first outcome of interest was reached, or (3) the date of final followup in those without events. Fiftynine participants fulfilled criteria for the primary outcome (34%) and 66 the secondary outcome (38%). Thirtyfour patients died (20%) with causes being cardiovascular (n=18), respiratory (n=4), sepsis (n=1) and unknown (n=15). There were additionally 28 (16%) heart failure hospitalisations, 10 (6%) syncopal events, 22 (13%) episodes of the acute coronary syndrome and 37 (21%) episodes of symtom progression to NYHA class IIIIV. Across all outcomes, MRproADM emerged as the biomarker with the best prognostic potential, being associated with HRs of 11 and 13 for the primary and secondary outcomes, respectively. The authors also looked at combining multiple biomarkers. Although the strongest dualbiomarker combination was NTproBNP combined with MRproADM, MRproADM remained stronger alone than in any combination.

Progressive improvements in technology over the last 20 years have increased diagnostic accuracy in all modalities and led to the incorporation of non-invasive imaging into many standard cardiac clinical care pathways. Cardiac imaging tests are requested by a variety of healthcare practitioners and performed in a range of settings from the most advanced hospitals to local health centres. Imaging is used to detect the presence and consequences of cardiovascular disease, as well as to monitor the response to therapies. The previous UK national imaging strategy statement which brought together all of the non-invasive imaging modalities was published in 2010. The purpose of this document is to collate contemporary standards developed by the modality-specific professional organisations which make up the British Cardiovascular Society Imaging Council, bringing together common and essential recommendations. The development process has been inclusive and iterative. Imaging societies (representing both cardiology and radiology) reviewed and agreed on the initial structure. The final document therefore represents a position, which has been generated inclusively, presents rigorous standards, is applicable to clinical practice and deliverable.

The beneficial effect of betablockers particularly applies to TTS patients with hypertension or cardiogenic shock. While this exciting finding validates an important risk reduction strategy in TTS survivors at longterm followup, Silverio et al’s results also bring up a seemingly paradoxical therapeutic dilemma in TTS patients with cardiogenic shock. Dynamic left ventricular outflow tract (LVOT) obstruction and worsening mitral regurgitation (MR) play important roles in TTSassociated cardiogenic shock. 3 Preceding myocardial structural abnormalities (hypertensive heart disease and basal septal hypertrophy, etc) may exacerbate LVOT obstruction on top of hyperdynamic motion of basal ventricular walls. There is a growing body of evidence that preexisting myocardial pathologies not only increase adverse haemodynamic events during TTS episodes but also are associated with persistent postTTS diastolic dysfunction and adverse outcomes. 4 5 This signifies the presence of certain specific conditions in some patients with TTS that warrants particular therapeutic strategies for longterm management and secondary prevention. A recent subset analysis of the DOREMI trial showed an outcome improvement in patients with cardiogenic shock who presented with betablockers on admission. Silverio et al’s results further highlight the possible prognostic benefits of early betablockade in TTS patients with cardiogenic shock. Betablockers are traditionally contraindicated in cardiogenic shock. Paradoxically, patients with TTS expected to benefit the most from early β-blockade are not expected to ‘tolerate’ this medication due to concern for worsening haemodynamic instability. In realworld practice, this may also result in an extended medication gap from the immediate hospitalisation period until outpatient followup visits, potentially depriving patients with TTS of the prognostic benefit from appropriate pharmacotherapy in the critical therapeutic window. Uncovering the unique pathophysiology underlying TTS may help solidify timely and effective therapeutic strategies. Brain natriuretic peptide (BNP) release in patients with TTS is usually more prominent than that in patients with acute myocardial infarction. Other than being a prognostic parameter, BNP release also causes natriuresis, vasodilatation and inhibition of the reninaldosterone system, which decreases mean arterial pressure and pulmonary capillary wedge pressure. Natriuresis, when combined with diuresis, may cause patients with TTS to become preload sensitive, precipitating hypotension and reflex tachycardia, resulting in ‘cardiogenic’ shock. In addition, a significant ventricular dilation during TTS episode easily leads to an assumption of pump failure and volume overload. Strict volume restriction or overdiuresis can cause inappropriately low ventricular preload","PeriodicalId":9311,"journal":{"name":"British Heart Journal","volume":"108 1","pages":"1243 - 1244"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44185443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
