Due to the small number of trials and their small size, potential risk of bias and concerns about imprecision and lack of applicability, we are uncertain of the effects of exercise-based CR compared to control on mortality, morbidity, cardiovascular hospital admissions, adverse events, return to work and health-related quality of life in people with stable angina. Low-quality evidence indicates that exercise-based CR may result in a small increase in exercise capacity compared to usual care. High-quality, well-reported randomised trials are needed to assess the benefits and harms of exercise-based CR for adults with stable angina. Such trials need to collect patient-relevant outcomes, including clinical events and health-related quality of life. They should also assess cost-effectiveness, and recruit participants that are reflective of the real-world population of people with angina.

ObjectiveA systematic review was undertaken to assess the effects of exercise-based cardiac rehabilitation (CR) for patients with stable angina.MethodsDatabases (Cochrane Central Register of Controlled Trials, MEDLINE, Embase and CINAHL) were searched up to October 2017, without language restriction. Randomised trials comparing CR programmes with no exercise control in adults with stable angina were included. Where possible, study outcomes were pooled using meta-analysis. Grading of Recommendations Assessment, Development and Evaluation was used to assess the quality of evidence. The protocol was published on the Cochrane Database of Systematic Reviews.ResultsSeven studies (581 patients), with a median of 12-month follow-up, were included. The effect of exercise-based CR on all-cause mortality (risk ratio (RR) 1.01, 95 % CI: 0.18 to 5.67), acute myocardial infarction (RR 0.33, 95% CI: 0.07 to 1.63) and cardiovascular-related hospital admissions (RR 0.14, 95% CI: 0.02 to 1.1) relative to control were uncertain. We found low-quality evidence that exercise-based CR results in a moderate improvement in exercise capacity (standard mean difference 0.45, 95% CI: 0.20 to 0.70). There was limited and very low-quality evidence for the effect of exercise-based CR on health-related quality of life (HRQoL), adverse events and costs. No data were identified on cost-effectiveness or return to work.ConclusionsExercise-based CR may improve the short-term exercise capacity of patients with stable angina pectoris. Well-designed randomised controlled trials are needed to definitely determine the impact of CR on outcomes including mortality, morbidity, HRQoL, and costs in the population of patients with stable angina receiving contemporary medical therapy.

An increasingly reported entity, Lemierre's syndrome classically presents with a recent oropharyngeal infection, internal jugular vein thrombosis and the presence of anaerobic organisms such asFusobacterium necrophorum. The authors report a normally fit and well 17-year-old boy who presented with severe sepsis following a 5-day history of a sore throat, myalgia and neck stiffness requiring intensive care admission. Blood cultures grewF. necrophorumand radiological investigations demonstrated left internal jugular vein, cavernous sinus and sigmoid sinus thrombus, left vertebral artery dissection and thrombus within the left internal carotid artery. Imaging also revealed two areas of acute ischaemia in the brain, consistent with septic emboli, skull base (clival) osteomyelitis and an extensive epidural abscess. The patient improved on meropenem and metronidazole and was warfarinised for his cavernous sinus thrombosis. He has an on-going left-sided hypoglossal (XIIth) nerve palsy.

Acute myocardial infarction (AMI) is a major cause of morbidity and mortality worldwide. Timely reperfusion with primary percutaneous coronary intervention (PPCI) remains the gold standard in patients presenting with ST-segment elevation myocardial infarction (STEMI), limiting infarct size, preserving left ventricular ejection fraction (LVEF), and improving clinical outcomes. Despite this, a significant proportion of STEMI patients develop post-infarct heart failure. We review the current understanding and up-to-date evidence base for therapeutic intervention of ischaemia-reperfusion injury (IRI), a combination of myocardial ischaemia secondary to acute coronary occlusion and reperfusion injury leading to further myocardial injury and cell death. Multiple treatment modalities have been shown to be cardioprotective and reduce IRI in experimental animal models. Recent phase II/III randomised controlled trials (RCT) have assessed multiple cardioprotective strategies ranging from ischaemic conditioning, therapeutic hypothermia and hyperoxaemia to pharmacological therapies. While several therapies have been shown to reduce infarct size in animal models or proof-of-concept studies, many larger scale trial results have proven inconsistent and disappointing. Hard clinical outcomes remain elusive. We discuss potential reasons for the difficulties in translation to clinical practice.

ObjectivesAssessing the impact of a new integrated heart failure service (IHFS) in a medium-sized district general hospital (DGH) on heart failure (HF) mortality, readmission rates, and provision of HF care.MethodsA retrospective, observational study encompassing all patients admitted with a diagnosis of HF over two 12-month periods before (2012/2013), and after (2015/2016) IHFS establishment.ResultsTotal admissions for HF increased by 40% (385 vs 540), with a greater number admitted to the cardiology ward (231 vs 121). After IHFS implementation, patients were more likely to see a cardiologist (35.1% vs 43.7%, p=0.009), undergo echocardiography (70.1% vs 81.5%, p<0.001), be initiated on all three disease modifying HF medications (angiotensin-converting enzyme inhibitors (ACEi), angiotensin II receptor blockers (ARB) and mineralocorticoid receptor antagonists (MRA)) in the heart failure with reduced ejection fraction (HFrEF) group (42% vs 99%, p<0.001) and receive specialist HF input (81.6% vs 85.4%, p=0.2). Both 30-day post-discharge mortality and HF related readmissions were significantly lower in patients with heart failure with preserved ejection fraction (HFpEF) (8.9% vs 3.1%, p=0.032, 58% reduction, p=0.043 respectively) with no-significant reductions in all other HF groups. In-patient mortality was similar. Length of stay in Cardiology wards increased from 8.4 to 12.7 days (p<0.001).ConclusionEstablishment of an IHFS within a DGH with limited resources and only a modest service re-design has resulted in significantly improved provision of specialist in-patient care, use of HFrEF medications, early heart failure nurse follow-up, and is associated with a reduction in early mortality, particularly in the HFpEF cohort, and HF related readmissions.
