IntroductionKounis syndrome is an uncommon clinical presentation of acute coronary syndrome secondary to an allergic or hypersensitivity reaction, especially anaphylaxis. It results when inflammatory mediators are released following mast cell activation, some of these mediators cause coronary artery vasospasm and may initiate thrombus formation in susceptible individuals. Although Kounis syndrome is becoming more widely known, many clinicians are still unaware of its existence. We present a case report and a literature review of the pre-hospital treatment of Kounis syndrome by emergency medical services.MethodsA literature search of the EMBASE, MEDLINE and PubMed electronic medical databases was conducted using the terms ‘Kounis syndrome’, ‘allergic acute coronary syndrome’ and ‘allergic myocardial infarction’. The purpose of the literature search was to identify the pre-hospital treatment of Kounis syndrome by emergency medical services. We included case reports of Kounis syndrome that described the medical treatment provided by emergency medical services, published any time up to October, 2017.ResultsAnaphylaxis is the most commonly treated component of Kounis syndrome by emergency medical services (66% of reported cases). Both components of Kounis syndrome, anaphylaxis and acute coronary syndrome, were treated in 16% of reported cases. No specific treatment was provided for either component of Kounis syndrome in 16% of reported cases.ConclusionThe pre-hospital treatment of Kounis syndrome by emergency medical services is infrequently reported in the literature. Kounis syndrome involves two distinct clinical conditions, both of which should be considered during treatment.

The Impact

BackgroundCardiovascular comorbidity is common among patients with chronic obstructive pulmonary disease (COPD) and there is concern that long-acting bronchodilators (long-acting muscarinic antagonists (LAMAs) and long-acting beta2 agonists (LABAs)) may further increase the risk of acute coronary events. Information about the impact of treatment intensification on acute coronary syndrome (ACS) risk in real-world settings is limited. We undertook a nationwide nested case–control study to estimate the risk of ACS in users of both a LAMA and a LABA relative to users of a LAMA.MethodsWe used routinely collected national health and pharmaceutical dispensing data to establish a cohort of patients aged >45 years who initiated long-acting bronchodilator therapy for COPD between 1 February 2006 and 30 December 2013. Fatal and non-fatal ACS events during follow-up were identified using hospital discharge and mortality records. For each case we used risk set sampling to randomly select up to 10 controls, matched by date of birth, sex, date of cohort entry (first LAMA and/or LABA dispensing), and COPD severity.ResultsFrom the cohort (n=83 417), we identified 5399 ACS cases during 281 292 person-years of follow-up. Compared with current use of LAMA therapy, current use of LAMA and LABA dual therapy was associated with a higher risk of ACS (OR 1.28 (95% CI 1.13 to 1.44)). The OR in an analysis restricted to fatal cases was 1.46 (95% CI 1.12 to 1.91).ConclusionIn real-world clinical practice, use of two versus one long-acting bronchodilator by people with COPD is associated with a higher risk of ACS.

Abstract Background In our previous 5-year cohort study, we demonstrated that low gene expression of nerve growth factor receptor (NGFR) in peripheral leucocytes in acute coronary syndrome (ACS) predicted repetitive coronary interventions at the de novo lesions. An NGFR-positive cell has been demonstrated to reside in bone marrow (BM) stromal fraction and to be increased in peripheral blood mononuclear cell (MNCs) fraction in patients with ischemic heart disease. Purpose To investigate whether the BM-NGFR+ cell is associated with arterial remodeling and the relationship between the levels of peripheral NGFR+ cells after ACS and coronary plaque progression in an experimental and prospective clinical study. Methods and results In an experimental study, 8-week-old C57B6/J wild type male mice were subjected to irradiation with 9.6 Gy and transplantation with BM (BMT) isolated from GFP-transgenic NGFR wild type (WT) or knock-out (KO) mice at day 1. Four weeks after BMT, the right carotid artery was ligated for 4 weeks. Induced neointimal area was increased (p<0.05), where cells under apoptosis were decreased (p<0.05) in NGFR-KO-BMT group compared to WT-BMT group (n=4). NGFR+ cells were not detected in wild type sham-operated artery, whereas in the ligated artery in WT-BMT group NGFR+ cells assembled in the developed neointima and exclusively presented double positive with GFP, but absent in NGFR-KO-BMT group (p<0.05, n=4). In a clinical study, thirty patients with ACS who underwent primary percutaneous coronary intervention (PCI) were enrolled. The peripheral blood sample was collected on days 0, 3 and 7, and 9 months follow-up and the number of NGFR+MNCs were measured by flowcytometric analysis. The plaque volume at non-targeted coronary lesion (non-TL:>5 mm proximal or distal to the implanted stents) were quantitatively analysed using gray-scale intravascular ultrasound (IVUS) and Q-IVUS™ software at the acute phase and 9 months follow-up. The number of NGFR+MNCs in peripheral blood was 1.5-fold increased at day 3 (0.064±0.056%) compared to day 0 (0.042±0.030%) (p<0.05). The change in normalized total plaque volume (TAVN) at non-TL at 9 months was negatively correlated with the number of NGFR+MNCs at day 0 (r=−0.51), day 3 (r=−0.51) and 9 months (r=−0.59) after ACS (p<0.05). Multiple regression analysis showed that NGFR+MNCs at day 0 (β=−0.48, p=0.01) and CRP (β=−0.53, P<0.01) are independent factors associating with TAVN change at non-TL at 9 months, regardless of LDL-cholesterol control level. ROC analysis revealed that NGFR+MNCs <0.049 at day 0 predicted the increase of TAVN with AUC 0.78; sensitivity 0.82 and specificity 0.67. Conclusions Bone marrow-derived peripheral NGFR+ cells negatively regulate arterial remodeling through appropriate apoptosis of neointimal cells and the peripheral level of NGFR+ cells in ACS predicts plaque progression at the non-targeted lesion.

Plaque Erosion

Abstract Background Plaque erosion (PE) is responsible for at least one-third of acute coronary syndrome (ACS). Inflammatory activation is considered a key mechanism of plaque instability in patients with plaque rupture through the release of metalloproteinases and the inhibition of collagen synthesis that in turns lead to fibrous cap degradation. However, the clinical relevance of macrophage infiltration has never been investigated in patients with PE. Purpose In our study, we aimed at assessing the presence of optical coherence tomography (OCT)-defined macrophage infiltrates (MØI) at the culprit site in ACS patients with PE, evaluating their clinical and OCT correlates, along with their prognostic value. Methods ACS patients undergoing OCT imaging and presenting PE as culprit lesion were retrospectively selected. Presence of MØI at culprit site and in non-culprit segments along the culprit vessel was assessed. The incidence of major adverse cardiac events (MACEs), defined as the composite of cardiac death, recurrent myocardial infarction and target vessel revascularization (TVR), was assessed [follow-up median (interquartile range, IQR) time 2.5 (2.03–2.58) years]. Results We included 153 patients [median age (IQR) 64 (53–75) years, 99 (64.7%) males]. Fifty-one (33.3%) patients presented PE with MØI and 102 (66.7%) PE without MØI. Patients having PE with MØI compared with PE patients without MØI had more vulnerable plaque features both at culprit site and at non-culprit segments. In particular, culprit lesion analysis demonstrated that patients with PE with MØI had a significantly thinner fibrous cap [median (IQR) 100 (60–120) μm vs. 160 (95–190) μm, p<0.001], higher prevalence of thrombus [41 (80.4%) vs. 64 (62.7%), p=0.028], lipid plaque [39 (76.5%) vs. 50 (49.0%), p<0.001], TCFA [20 (39.2%) vs. 14 (13.7%), p=0.001], and a higher maximum lipid arc [median [IQR] 250.0° (177.5°-290.0°) vs. 190.0° (150.0°-260.0°), p=0.018) at the culprit lesion compared with PE without MØI. MACEs were significantly more frequent in PE with MØI patients compared with PE without MØI [11 (21.6%) vs. 6 (5.9%), p=0.008], mainly driven by a higher risk of cardiac death and TVR. At multivariable Cox regression model, PE with MØI [HR=2.95, 95% CI (1.09–8.02), p=0.034] was an independent predictor of MACEs. Conclusion Our study demonstrates that among ACS patients with PE the presence of MØI at culprit lesion is associated with a more aggressive phenotype of coronary atherosclerosis with more vulnerable plaque features, along with a worse prognosis at a long-term follow-up. These findings are of the utmost importance in the era of precision medicine because clearly show that macrophage infiltrates may identify patients with a higher cardiovascular risk requiring more aggressive secondary prevention therapies and a closer clinical follow-up.

Cardiovascular disease is one of the most common causes of hospitalization and is associated with high morbidity and mortality rates. Among the most important modifiable and well-known risk factors are an unhealthy diet and sedentary lifestyle. Nevertheless, adherence to healthy lifestyle regimes is poor. The present study examined longitudinal trajectories (pre-event, 6-, 12-, 24-, 36-, and 60-month follow-ups) of protein intake (fish, legumes, red/processed meat) and physical activity in 275 newly-diagnosed patients with acute coronary syndrome. Hierarchical Generalized Linear Models were performed, controlling for demographic and clinical variables, the season in which each assessment was made, and the presence of anxiety and depressive symptoms. Significant changes in protein intake and physical activity were found from pre-event to the six-month follow-up, suggesting the adoption of healthier behaviors. However, soon after the six-month follow-up, patients experienced significant declines in their healthy behaviors. Both physical activity and red/processed meat intake were modulated by the season in which the assessments took place and by anxiety symptoms over time. The negative long-term trajectory of healthy behaviors suggests that tailored interventions are needed that sustain patients’ capabilities to self-regulate their behaviors over time and consider patient preference in function of season.

Abstract Introduction Ischaemic stroke (IS) risk after acute coronary syndrome is increasing. The aim of our study was to evaluate the stroke rate in a multicentre study and to determine the prediction ability of the PRECISE DAPT score, added to the prediction power of the GRACE score, already demonstrated. Methods This was a retrospective study, carried out in two centres with 5916 patients, with ACS discharged between 2011 and 2017 (median 66±13 years, 27.7% women). The primary endpoint was the occurrence of ischaemic stroke and its risk during follow up (median 5.5, IQR 2.6–7.0). Results A multivariable logistic regression analysis was made, where GRACE (HR 1.01, IC 95% 1.00–1.02) and PRECISE DAPT score (HR 1.03, IC 95% 1.01–1.05) were both an independent predictor of ischaemic stroke after ACS, in a model adjusted by age and AF, which was found to be the independent factor with highest risk (HR 1.67, IC 95% 1.09–2.55). Conclusions GRACE and PRECISE DAPT scores are ischaemic stroke predictors used during follow-up for patients after acute coronary syndrome. We should use both of them not only trying to predict ischaemic/haemorrhagic risk respectively but also as ischaemic stroke predictors. Figure 1.
