Prediction of incident atrial fibrillation in hypertrophic cardiomyopathy

BACKGROUND AND AIM

Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM) with significant effects on outcome. We aim to compare the left atrial (LA) diameter measurement with HCM-AF Score in predicting atrial fibrillation (AF) development in HCM.

METHODS

From the regional cohort of the Campania Region, Italy, 519 HCM patients (38% women, age45 ± 17 years) without history of AF, were enrolled in the study. The primary clinical endpoint was the development of AF, defined as at least 1 episode documented by ECG.

RESULTS

During the follow-up (mean 8 ± 6, IQ range 2.5-11.2 years), 99 patients (19%) developed AF. Patients who developed AF were more symptomatic, had higher prevalence of ICD implantation, had larger LA diameter, greater left ventricular (LV) maximal wall thickness and LV outflow tract obstruction (p < 0.01). Both LA diameter and HCM-AF score were higher in patients who developed AF versus those who did not (LA diameter 49 ± 7 versus 43 ± 6 mm; HCM-AF score 22 ± 4 versus 19 ± 4; p < 0.0001); however, ROC curve analysis demonstrated that LA diameter had a significant greater area under the curve than HCM-AF Score (p < 0.0001). At 5 years follow-up, a LA diameter > 46 mm, showed a similar accuracy in predicting AF development of HCM-AF score ≥ 22, which identifies patients at high risk to develop AF.

CONCLUSION

Our analysis shows that LA diameter, a worldwide and simple echocardiographic measure, is capable alone to predict AF development in HCM patients.

Reproducibility of an artificial intelligence optical coherence tomography software for tissue characterization: Implications for the design of longitudinal studies

BACKGROUND

To assess the reproducibility of coronary tissue characterization by an Artificial Intelligence Optical Coherence Tomography software (OctPlus, Shanghai Pulse Medical Imaging Technology Inc.).

METHODS

74 patients presenting with multivessel ST-segment elevation myocardial infarction (STEMI) underwent optical coherence tomography (OCT) of the infarct-related artery at the end of primary percutaneous coronary intervention (PPCI) and during staged PCI (SPCI) within 7 days thereafter in the MATRIX (Minimizing Adverse Hemorrhagic Events by Transradial Access Site and angioX) Treatment-Duration study (ClinicalTrials.gov, NCT01433627). OCT films were run through the OctPlus software. The same region of interest between either side of the stent and the first branch was identified on OCT films for each patient at PPCI and SPCI, thus generating 94 pairs of segments. 42 pairs of segments were re-analyzed for intra-software difference. Five plaque characteristics including cholesterol crystal, fibrous tissue, calcium, lipid, and macrophage content were analyzed for various parameters (span angle, thickness, and area).

RESULTS

There was no statistically significant inter-catheter (between PPCI and SPCI) or intra-software difference in the mean values of all the parameters. Inter-catheter correlation for area was best seen for calcification [intraclass correlation coefficient (ICC) 0.86], followed by fibrous tissue (ICC 0.87), lipid (ICC 0.62), and macrophage (ICC 0.43). Some of the inter-catheter relative differences for area measurements were large: calcification 9.75 %; cholesterol crystal 74.10 %; fibrous tissue 5.90 %; lipid 4.66 %; and macrophage 1.23 %. By the intra-software measurements, there was an excellent correlation (ICC > 0.9) for all tissue types. The relative differences for area measurements were: calcification 0.64 %; cholesterol crystal 5.34 %; fibrous tissue 0.19 %; lipid 1.07 %; and macrophage 0.60 %. Features of vulnerable plaque, minimum fibrous cap thickness and lipid area showed acceptable reproducibility.

CONCLUSION

The present study demonstrates an overall good reproducibility of tissue characterization by the Artificial Intelligence Optical Coherence Tomography software. In future longitudinal studies, investigators may use discretion in selecting the imaging endpoints and sample size, accounting for the observed relative differences in this study.

Aortic Root Diameter in Highly-Trained Competitive Athletes: Reference Values According to Sport and Prevalence of Aortic Enlargement

BACKGROUND

Studies exploring the extent of aortic root dilation across the different types of sport are limited. We aimed to define the physiological limits of aortic remodelling in a large population of healthy elite athletes in comparison with nonathletic controls.

METHODS

A total of 1995 consecutive athletes evaluated at the Institute of Sports Medicine (Rome, Italy) and 515 healthy controls underwent a comprehensive cardiovascular screening. The aortic diameter was measured at the level of the sinuses of Valsalva. The 99th percentile from the mean of the aortic diameter in the control population was used to define an abnormally enlarged aortic root dimension.

RESULTS

Athletes showed a larger aortic root diameter (30.6 [± 3.3] vs 28.1 [± 3.1] mm, P value < 0.001) than controls. The difference was evident in male and female athletes, regardless of sport- predominant component and level of intensity. The 99th percentile value for aortic root diameter in control male and female subjects was 37 mm and 32 mm, respectively. Based on these values, 50 (4.2%) male and 21 (2.6%) female athletes would have been diagnosed with an enlarged aortic root. However, aortic root diameter of clinical relevance-ie, ≥ 40 mm-was observed in only 17 male athletes (0.85%) and did not exceed > 44 mm.

CONCLUSIONS

Athletes show a mild, although significant, increased aortic dimension in comparison with healthy controls. The degree of aortic enlargement varies in relation to type of sports and sex. Eventually, only a small minority of athletes exhibited a markedly enlarged aortic diameter (ie, ≥ 40 mm) in a range of clinical relevance.

Everolimus-eluting bioresorabable scaffold system in the treatment of cardiac allograft vasculopathy: the cardiac allograft reparative therapy (CART) prospective multicentre pilot study

Background

Cardiac allograft vasculopathy (CAV) is still the main drawback of heart transplantation (HTx) and percutaneous coronary intervention (PCI) is a palliative measure because of the high incidence of PCI failure. The bioresorbable scaffolds (BRS) could represent a potential novel therapeutic tool for the treatment of coronary obstructions in CAV.

Purpose

To investigates the effects of BRS implantation in CAV patients in a Nationwide prospective study.

Methods

Multicentre, single-arm, prospective, open-label study that included patients affected by advanced CAV treated with PCI and second-generation ABSORB BRS. The primary endpoint was the incidence of 12-month angiographic in-segment scaffold restenosis (ISSR). Secondary endpoints were the composite of cardiac death, myocardial infarction, and target lesion revascularisation at 12-and 36-month follow-up and the incidence of ISSR at 36 months. A paired analysis of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) at baseline and follow-up was also performed.

Results

Between 2015–2017 35 HTx patients were enrolled and treated on 44 coronary lesions with 51 BRS. The primary endpoint occurred in 13.5% of the lesions (5/37), with a cumulative ISSR rate up to 3 years of 16.2% (6/37).Angiographic lumen loss was 0.40±0.62mm at 12 months and 0.53±0.57mm at 36 months. Overall survival was 91.4% and 74.3%, and MACEs 14.2% and 31.4% at 12 and 36 months, respectively. At the paired intracoronary imaging analysis a significant increase of the vessel external elastic membrane area in the treated segment of the BRS was described at the OCT, while some progression of CAV was detected proximally at the IVUS assessment.

Conclusions

BRS in CAV was feasible and safe, with an ISSR incidence similar to drug-eluting stents. For the first time, a positive remodeling was observed in HTx patients after PCI. Vessel enlargement and the lack of metallic stents may allow repeated PCI avoiding the vessel shrinkage caused by the addition of multiple metal layers, being CAV a complex clinical scenario with a high incidence of MACEs, mainly driven by PCI failure.

Radial versus femoral access in ACS patients undergoing complex PCI is associated with consistent bleeding benefit and no excess of risks

BACKGROUND

The comparative effectiveness of transradial (TRA) compared with transfemoral access (TFA) in acute coronary syndrome (ACS) patients undergoing complex percutaneous coronary intervention (PCI) remains unclear.

METHODS

Among 8,404 ACS patients in the Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and Systemic Implementation of angioX (MATRIX)-Access trial, 5,233 underwent noncomplex (TRA, n=2,590 and TFA, n=2,643) and 1,491 complex PCI (TRA, n=777 and TFA, n=714). Co-primary outcomes were major adverse cardiovascular events (MACE, the composite of all-cause mortality, myocardial infarction, or stroke) and the composite of MACE and BARC type 3-5 bleeding (net adverse cardiovascular events, NACE) at 30 days.

RESULTS

Rates of 30-day MACE (hazard ratio [HR]:0.94; 95% confidence interval [CI]:0.72-1.22) or NACE (HR:0.89; 95% CI:0.69-1.14) did not significantly differ between groups in the complex PCI group, whereas both primary endpoints were lower (HR:0.84; 95% CI:0.70-1.00, HR:0.83; 95% CI:0.70-0.98, respectively) with TRA among noncomplex PCI patients, with negative interaction testing (P_int 0.473 and 0.666, respectively). Access-site BARC type 3 or 5 bleeding was lower with TRA, consistently among complex (HR:0.18; 95% CI:0.05-0.63) and noncomplex (HR:0.41; 95% CI:0.20-0.85) PCI patients, whereas the former group had a greater absolute risk reduction of 1.7% (number needed to treat: 59) due to their higher absolute risk.

CONCLUSIONS

Among ACS patients, PCI complexity does not affect the comparative efficacy and safety of TRA versus TFA, whereas the absolute risk reduction of access-site major bleeding was greater with TRA compared with TFA in complex as opposed to noncomplex PCI.

596 Multidisciplinary in-depth investigation in a young athlete suffering from syncope caused by myocardial bridge

Aims

Laboratory medicine along with genetic investigations are taking on an increasingly important role in monitoring athlete’s health conditions. Acute or intense exercise can lead to metabolic imbalances, muscle injuries, or can point up cardiovascular disorders.

Methods and results

This study aimed to monitor the health status of a basketball player, through an integrated approach including biochemical and genetic investigations and advanced imaging techniques, to shed light on the causes of recurrent syncope he experienced during exercise. Biochemical analyses showed that the athlete had abnormal iron, ferritin, and bilirubin levels. Coronary computed tomographic angiography highlighted the presence of an intramyocardial bridge, suggesting this may be the cause of the observed syncopes. The athlete was excluded from competitive activity. To understand if this cardiac malformation could be caused by an inherited genetic condition, both array-CGH and whole exome sequencing were performed. Array-CGH showed two intronic deletions involving MACROD2 and COMMD10 genes, which could be related to the congenital heart defect; the whole exome sequencing highlighted the genotype compatible with the Gilbert syndrome. However, no clear pathogenic mutations related to the patient’s cardiological phenotype were detected, even after applying machine learning methods.

Conclusions

This case highlights the importance and the need to provide exhaustive personalized diagnostic work-up for the athletes to cover the cause of their malaise, safeguarding their health. This multidisciplinary approach can be useful to create ad personam training and treatments, thus avoiding the appearance of diseases and injuries which, if underestimated, can become irreversible disorders and sometimes can lead to the death of the athlete.

Ultra-Short Term Evaluation of Coronary Vessel Wall Changes in Reference Segments Adjacent to Culprit Lesions in ST-Segment Elevation Myocardial Infarction

BACKGROUND

Culprit lesions of ST-segment elevation myocardial infarction (STEMI) patients are friable, soft, and prone to disruption during primary percutaneous coronary intervention (pPCI). The presence of dissections in reference vessel segments (RVSs), adjacent to stented culprit lesions, and dynamic luminal changes in proximal or distal RVSs have not yet been investigated. We therefore sought to assess the healing patterns of edge dissections and the changes of lumen area at RVSs within 1 week post stent implantation in patients with STEMI.

METHODS

In the MATRIX trial (ClinicalTrials.gov NCT01433627), optical coherence tomography (OCT) was performed at the end of pPCI and within 1 week during staged PCI. The RVS dissection was defined as: type 1 = flap; type 2 = cavity; type 3 = double barrel; and type 4 = fissure. We compared separately the fate of residual dissection and luminal area/dimension by OCT in the target vessel between pPCI and staged PCI, including 1-year clinical outcomes.

RESULTS

Out of 151 patients, 46 patients had dissections in 50 RVSs and did not experience worse clinical outcome. Dissections were 44% type 1, 28% type 2, 12% type 3, and 16% type 4. Overall, 18% of the dissections healed. The mean lumen area of the RVS enlarged in 82 patients (59%) from pPCI to staged PCI. Compared with the proximal RVS, there was a significant increase in the lumen diameter at the distal RVS (0.06 ± 0.25 mm vs -0.01 ± 0.21 mm; P=.01).

CONCLUSION

Dissections occur frequently after pPCI. One-fifth of them heal within 1 week and do not seem to negatively impact clinical outcomes. Distal RVS lumen area increased compared with proximal RVS, likely reflecting a different vasoconstriction pattern over time.

Impact of optical coherence tomography findings on clinical outcomes in ST-segment elevation myocardial infarction patients: a MATRIX (Minimizing Adverse Hemorrhagic Events by Trans-radial Access Site and angioX) OCT sub-study

PURPOSE

To investigate the association of the degree of stent expansion, as assessed by optical coherence tomography (OCT), following stent implantation, and clinical outcomes in ST-segment elevation myocardial infarction (STEMI) patients.

METHODS

STEMI patients from the MATRIX (Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and angioX) OCT study were selected; Clinical outcomes were collected through 1 year. Stent expansion index is a minimum stent area (MSA) divided by average lumen area (average of proximal and distal reference lumen area). The following variables were measured: MSA (< 4.5mm²), dissection (> 200 µm in width and < 5 mm from stent segment), malapposition (> 200 µm distance of stent from vessel wall), a thrombus (area > 5% of lumen area) were compared.

RESULTS

A total of 151 patients were included; after excluding patients with suboptimal OCT quality, the population with available OCT was classified into 2 groups: under-expanded < 90% (N = 72, 51%) and well-expanded ≥ 90% (N = 67, 49%). In the well-expanded group, a significant number of the proximal vessels had a lumen area < 4.5mm² (16.1%, p < 0.001) and a greater thrombus burden within stent (56.7%, p = 0.042). The overall 30 day and 1 year major adverse cardiovascular event (MACE) rates were 5% and 6.1%, respectively.

CONCLUSION

Irrespective of the degree of stent expansion, the OCT findings, in STEMI patients, and the MACE at 30 days and one year follow up was low; further, well-expanded stents led to a more significant residual thrombotic burden within the stent but seemed to have insignificant clinical impact. Acknowledged stent optimization criteria, traditionally related to worse outcomes in stable patients, do not seem to be associated with worse outcomes in this STEMI population.

Effect of body mass index on ischemic and bleeding events in patients presenting with acute coronary syndromes: insights from the START-ANTIPLATELET registry

Background

The protective effect of obesity on mortality in acute coronary syndromes (ACS) patients remains debated. We aimed at evaluating the impact of obesity on ischemic and bleeding events as possible explanations to the obesity paradox in ACS patients.

Methods

For the purpose of this sub-study, patients enrolled in the START-ANTIPLATELET registry were stratified according to Body Mass Index (BMI) into three groups: normal, BMI &lt;25kg/m2; overweight, BMI: 25–29.9kg/m2; obese, BMI ≥30kg/m2. The primary endpoint was net adverse clinical endpoints (NACE), defined as a composite of all-cause death, myocardial infarction (MI), stroke, and major bleeding.

Results

Patients were classified as follows: 410 (33.9%) normal, 538 (44.5%) overweight, 261 (21.6%) obese. Compared to the normal weight group, obese and overweight patients had a higher prevalence of cardiovascular risk factors, but were younger, with a better left ventricular ejection fraction (LVEF) and lower PRECISE-DAPT score. At one-year follow-up NACE was more frequently observed in normal than in overweight and obese patients (15.1%,8.6%,and9.6%, respectively; p=0.004), driven by a significantly higher rate of all-cause death (6.3%,2.6%, and 3.8%, respectively; p=0.008), while no significant differences were noted in terms of MI, stroke, and major bleeding. When correcting for confounding variables, BMI loses its power in independently predicting outcomes, failing to confirm the obesity paradox in a real-world ACS population.

Conclusions

Our study conflicts the obesity paradox in real-world ACS population, and suggest that the reduced mortality rate may be explained by a lower bleeding risk in obese patients allowing a more aggressive medical treatment, and by a better LVEF translating into a higher survival rate.

Activating stimuli induce platelet microRNA modulation and proteome reorganisation

Platelets carry megakaryocyte-derived mRNAs whose translation efficiency before and during activation is not known, although this can greatly affect platelet functions, both under basal conditions and in response to physiological and pathological stimuli, such as those involved in acute coronary syndromes. Aim of the present study was to determine whether changes in microRNA (miRNA) expression occur in response to activating stimuli and whether this affects activity and composition of platelet transcriptome and proteome. Purified platelet-rich plasmas from healthy volunteers were collected and activated with ADP, collagen, or thrombin receptor activating peptide. Transcriptome analysis by RNA-Seq revealed that platelet transcriptome remained largely unaffected within the first 2 hours of stimulation. In contrast, quantitative proteomics showed that almost half of > 700 proteins quantified were modulated under the same conditions. Global miRNA analysis indicated that reorganisation of platelet proteome occurring during activation reflected changes in mature miRNA expression, which therefore, appears to be the main driver of the observed discrepancy between transcriptome and proteome changes. Platelet functions significantly affected by modulated miRNAs include, among others, the integrin/cytoskeletal, coagulation and inflammatory-immune response pathways. These results demonstrate a significant reprogramming of the platelet miRNome during activation, with consequent significant changes in platelet proteome and provide for the first time substantial evidence that fine-tuning of resident mRNA translation by miRNAs is a key event in platelet pathophysiology.

Prevalence and clinical significance of cardiovascular abnormalities in patients with the LEOPARD syndrome

The aim of this study was to characterize cardiovascular involvement in a large number of patients with LEOPARD syndrome. Twenty-six patients (age range 0 to 63 years, median age at the time of the study evaluation 17 years) underwent clinical and genetic investigations. Familial disease was ascertained in 9 patients. Nineteen patients (73%) showed electrocardiographic abnormalities. Left ventricular (LV) hypertrophy was present in 19 patients (73%), including 9 with LV outflow tract obstructions; right ventricular hypertrophy was present in 8 patients (30%). Valve (57%) and coronary artery (15%) anomalies were also observed. Single patients showed LV apical aneurysm, LV noncompaction, isolated LV dilation, and atrioventricular canal defect. During follow-up (9.1 +/- 4.5 years), 2 patients died suddenly, and 2 patients had cardiac arrest. These patients had LV hypertrophy. Despite the limited number of subjects studied, genotype-phenotype correlations were observed in familial cases. In conclusion, most patients with LEOPARD syndrome showed LV hypertrophy, often in association with other valvular or congenital defects. A spectrum of underrecognized cardiac anomalies were also observed. Long-term prognosis was benign, but the occurrence of 4 fatal events in patients with LV hypertrophy indicates that such patients require careful risk assessment and, in some cases, consideration for prophylaxis against sudden death.

Obesity, inflammation, and vascular disease: the role of the adipose tissue as an endocrine organ

Insulin resistance, both in nondiabetic and diabetic subjects, is frequently associated with obesity, particularly with an excess of central fat. With the growing prevalence of obesity, scientific interest in the biology of adipose tissue has been extended to the secretory products of adipocytes, since they are increasingly shown to influence several aspects in the pathogenesis of obesity-related diseases Until relatively recently, the role of fat itself in the development of obesity and its consequences was considered to be a passive one; adipocytes were considered to be little more than storage cells for fat. It is now clear that, in addition to storing calories as triglycerides, they also secrete a large variety of proteins, including cytokines, chemokines and hormone-like factors, such as leptin, adiponectin and resistin. This production of pro-atherogenic chemokines by adipose tissue is of particular interest since their local secretion, e.g. by perivascular adipose depots, may provide a novel mechanistic link between obesity and the associated vascular complications. Recent research has revealed many functions of adipocytokines extending far beyond metabolism, such as immunity, cancer and bone formation. This remarkable understanding is allowing us to more clearly define the role that adipocytes play in health and in obesity and how inflammatory mediators act as signaling molecules in this process. Moreover, on a molecular level, we are beginning to comprehend how such variables as hormonal control, exercise, food intake, and genetic variation interact and result in a given phenotype, and how pharmacological intervention may modulate adipose tissue biology.

Resistin promotes smooth muscle cell proliferation through activation of extracellular signal-regulated kinase 1/2 and phosphatidylinositol 3-kinase pathways

BACKGROUND

Resistin, a novel adipokine, is elevated in patients with type 2 diabetes and may play a role in the vascular complications of this disorder. One recent study has shown that resistin has a proinflammatory effect on endothelial cells. However, there is no information on whether resistin could also affect vascular smooth muscle cells (SMCs). Thus, the purpose of this study was to assess whether resistin could induce SMC proliferation and to study the mechanisms whereby resistin signals in SMCs.

METHODS AND RESULTS

Human aortic smooth muscle cells (HASMCs) were stimulated with increasing concentrations of resistin for 48 hours. Cell proliferation was induced by resistin in a dose-dependent manner as assessed by direct cell counting. To gain more insights into the mechanism of action of resistin, we investigated the extracellular signal-regulated kinase (ERK) and/or phosphatidylinositol 3-kinase (PI3K) signaling pathways. Transient phosphorylation of the p42/44 mitogen-activated protein kinase (ERK 1/2) occurred after addition of resistin to HASMCs. U0126, a specific inhibitor of ERK phosphorylation, significantly inhibited ERK 1/2 phosphorylation and reduced resistin-simulated proliferation of HASMCs. LY294002, a specific PI3K inhibitor, also significantly inhibited HASMC proliferation after resistin stimulation.

CONCLUSIONS

Our results demonstrate that resistin induces HASMC proliferation through both ERK 1/2 and Akt signaling pathways. The proliferative action exerted by resistin on HASMCs may account in part for the increased incidence of restenosis in diabetes patients.

Multitasking of the 3-hydroxy-3-methylglutaryl coenzyme a reductase inhibitor: Beyond cardiovascular diseases

Statins can profoundly affect cellular metabolism by inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase, which is the rate-limiting enzyme responsible for cholesterol synthesis. Many physicians prescribe statins to lower plasma cholesterol levels, which has beneficial effects in both the primary and secondary prevention of coronary artery disease. However, in vitro, in vivo, animal, and clinical studies have all shown that statins may also have important pleiotropic properties. In fact, a number of clinical studies have suggested that statins are involved in modulating diseases such as cancer, osteoporosis, and dementia (including Alzheimer's disease). However, because these studies have been only preliminary and observational in nature, large randomized, placebo-controlled studies are needed to confirm the modulatory role of statins in these important diseases.

Effects of recombinant active site-blocked activated factor VII in rabbit models of carotid stenosis and myocardial infarction

We tested the effects of human recombinant active site-blocked activated factor VII (rFVIIai) in a rabbit model of carotid artery thrombosis. Cyclic flow variations (CFVs), due to recurrent thrombus formation, were obtained in stenotic rabbit carotid arteries with endothelial injury. After 30 min of CFV, the animals received rFVIIai. If CFVs were abolished, animals were observed for 30 additional minutes, after which human recombinant activated factor VII was infused into the carotid artery to determine whether it could displace rFVIIai from tissue factor (TF), thus restoring CFV. An additional group of animals received rFVIIai to determine its duration of action. Recombinant FVIIai abolished CFVs in 8 of 9 rabbits (P < 0.01). This effect was reversible, as rFVIIa administration restored CFVs in all animals. A further study was initiated to assess whether TF-dependent reductions in coronary blood flow might contribute to the occurrence of myocardial injury during postischaemic reperfusion of rabbit hearts. Recombinant FVIIai resulted in significant reductions in both infarct size and no-reflow area, while rFVIIa produced a significant increase in both infarct size and no-reflow area. These data suggest that rFVIIai might be beneficial in patients with acute myocardial infarction undergoing reperfusion therapies.

Unusual extracranial complications of otitis media in a young HIV patient: retropharyngeal and Mouret's abscess

Since the introduction of antibiotic therapy, the incidence of intra- and extracranial suppurative complication of acute and chronic purulent otitis media has sharply decreased. In particular, reports of laterocervical abscesses secondary to this disorder are quite rare, not more than twenty cases of Bezold's or Mouret's abscesses having been reported in the literature during the last ten years. The authors present a case of retropharyngeal and Mouret's abscess developed as a consequence of acute purulent otitis media in a young Aids patient. True otologic manifestations of Aids are rare while the incidental association of otologic disease with Aids is more common. The development of complication in the present case is favoured by the patients severe immunodepression.
