Prognostic impact of antiplatelet therapy in Takotsubo syndrome: a systematic review and meta-analysis of the literature.

While the most recent evidence suggests a lack of benefit, antithrombotic therapy is still extensively prescribed in patients with Takotsubo syndrome (TTS). The objective of this study was to determine whether patients with TTS benefit from anti-aggregation, in terms of either short-term or long-term outcomes. A systematic review and meta-analysis was conducted. A comprehensive search of the literature included MEDLINE, Cochrane Library, Clinicaltrials.gov, EU Clinical Trial Register, References, and contact with the authors. Methodological quality assessment and data extraction were systematically performed. The review adhered to the PRISMA framework guidelines. A total of 86 citations were identified, six being eligible for inclusion, for a total of 1997 patients. One of them considered both short-term and long-term outcomes. One reported outcomes during the index event, while the remaining four focused on potential long-term benefits. They were all retrospective cohort studies.Based on our data, the long-term use of antiplatelet therapy (AT) led to a significantly higher incidence of the composite outcome (OR: 1.54; 95% CI 1.09-2.17; p = 0.014) and overall mortality (OR 1.72; 95% CI 1.07-2.77; p = 0.027). The analysis did not show a statistically significant difference in TTS recurrences, stroke/TIA, and MI or CAD worsening with AT compared with no anti-aggregation. The AT in this settings did not show any clear benefit in improving the long-term outcomes, and it may be even detrimental and it may be detrimental. These results warrant further future research and the design of adequately powered randomized controlled trials focusing on the impact of aspirin on the outcomes in patients presenting with TTS.

A Preliminary Case-Control Study: Peritoneal Approach in Congestive Heart Failure Treatment.

BACKGROUND: Congestive heart failure (CHF) associated with worsening renal function is a very common disorder, and, as well known, the goal of the treatment is reducing venous congestion and maintaining a targeted extracellular volume. The objective of the study is to evaluate regular peritoneal ultrafiltration treatment compared to a standard conservative approach in NYHA III-IV CHF patients. In particular, the primary endpoints of the study were the major event-free survival and the total days of medical care per month (which consist of the days of hospitalization and the number of outpatient visits). MATERIAL AND METHODS: This is a retrospective case-control study. Twenty-four patients were included in the present study. Twelve consecutive patients were treated with peritoneal treatment (group A) and 12 matched for age, gender, and severity of disease with a standard approach. Patients were observed over a maximum period of 18 months. Information on events, hospitalizations, and number of visits was collected during follow-up. RESULTS: During the follow-up, we observed a major event in 4 patients in group A (33.3%) and in 8 patients in group B (66.7%). In group B, we observed 7 deaths and 1 ICD shock, while in group A, 3 deaths and 1 ICD shock. The number of visits per month was significantly lower in patients treated with the peritoneal method (1.2 [0.4-4.1] vs. 2.5 [2.0-3.1]; p = 0.03). The total days of medical care was significantly lower in group A (2.0 [1.1-5.5] vs. 4.4 [3.0-8.7]; p = 0.034). A multiple event analysis according to the Andersen-Gill model showed a significant event-free survival for group A. During the follow-up, we did not observe any episode of peritonitis in the treated group. CONCLUSIONS: Our study shows that the peritoneal technique is a good therapeutic tool in well-selected patients with CHF. In accordance with prior experience, this intervention has not only an important and significant clinical impact but also potential economic and social consequences.

Occurrence, outcomes and predictors of portal hypertension in cystic fibrosis: A longitudinal prospective birth cohort study.

BACKGROUND: The reported prevalence of portal hypertension (PH) in Cystic Fibrosis is variable, incidence rates rarely provided and the utility of liver function tests (LFT's) early in life to predict PH is questionable. The aims were to (1) determine PH prevalence (P) and incidence rate (IR) and combined mortality transplant (MTX) data in PH vs non-PH patients and (2) to assess association of LFTs in early life with liver disease and PH. METHOD: (1) A double centre longitudinal cohort study of 577 CF patients diagnosed by newborn screening (NBS) with annual examinations for PH up to 18.5 years of age (max) was performed over 28 years for P, IR, and MTX data; (2) Cox proportional hazard models were used to assess the association of elevated LFTs on 2 or more occasions over 0-6.5 years and PH. RESULTS: 51/577(8.8%) developed PH with an average IR of near 3/1000 patient years per 5 year interval representing young, mid and late childhood respectively in patients 3-18 years of age. Combined mortality/liver transplant occurred in 12/51 (23.5%) PH and 25/526 (4.8%) non-PH (p < 0.001). Elevated enzymes particularly GGT (HR:5.71, 95% CI 3.11-10.47); ALT/GGT (HR: 5.56, 95% CI 2.82-10.98); and ALP/GGT (HR: 5.74, 95% CI 2.78-11.86) were associated with the onset of PH. CONCLUSION: This birth cohort with annual examination for PH provides an accurate assessment of the prevalence, and IR of PH and MTX of PH vs non-PH. Early elevated LFTs are associated with onset of MBC/PH.

Role of Speckle Tracking Echocardiography in the Evaluation of Breast Cancer Patients Undergoing Chemotherapy: Review and Meta-analysis of the Literature.

Diagnosis and management of Cancer therapeutics-related cardiac dysfunction is of crucial importance in breast cancer (BC) patients. The role of advanced echocardiographic techniques, such as deformation imaging, in the diagnosis and characterization of patients receiving cancer therapy has so far involved relatively small studies in the research setting. Therefore, we conducted a meta-analysis and systematic review of observational studies evaluating myocardial changes during chemotherapy detected through conventional echocardiographic parameters, such as 2D left ventricular ejection fraction (2D LVEF), and 2D Speckle tracking echocardiography (STE). The literature search retrieved 487 research works, articles, of which 17 were found to be pertinent with this topic. After full article review, 16 studies were considered suitable for the present analysis. Two separate analyses, one for the anthracyclines-based therapeutic regimen and one for the trastuzumab based therapeutic regimen, were performed. A significant reduction in 2D LVEF and 2D STE parameters during cancer therapy was found in both the investigations. Peak systolic global longitudinal strain demonstrated to be the most consistent 2D STE parameter in detecting early myocardial changes among all the studies. Thus, we confirmed the role of 2D STE for the early detection of myocardial damage, suggesting its crucial role in monitoring BC patients and eventually driving the introduction of cardioprotective treatment.

Sacubitril/valsartan eligibility and outcomes in the ESC-EORP-HFA Heart Failure Long-Term Registry: bridging between European Medicines Agency/Food and Drug Administration label, the PARADIGM-HF trial, ESC guidelines, and real world.

AIMS: To assess the proportion of patients with heart failure and reduced ejection fraction (HFrEF) who are eligible for sacubitril/valsartan (LCZ696) based on the European Medicines Agency/Food and Drug Administration (EMA/FDA) label, the PARADIGM-HF trial and the 2016 ESC guidelines, and the association between eligibility and outcomes. METHODS AND RESULTS: Outpatients with HFrEF in the ESC-EORP-HFA Long-Term Heart Failure (HF-LT) Registry between March 2011 and November 2013 were considered. Criteria for LCZ696 based on EMA/FDA label, PARADIGM-HF and ESC guidelines were applied. Of 5443 patients, 2197 and 2373 had complete information for trial and guideline eligibility assessment, and 84%, 12% and 12% met EMA/FDA label, PARADIGM-HF and guideline criteria, respectively. Absent PARADIGM-HF criteria were low natriuretic peptides (21%), hyperkalemia (4%), hypotension (7%) and sub-optimal pharmacotherapy (74%); absent Guidelines criteria were LVEF>35% (23%), insufficient NP levels (30%) and sub-optimal pharmacotherapy (82%); absent label criteria were absence of symptoms (New York Heart Association class I). When a daily requirement of ACEi/ARB ≥ 10 mg enalapril (instead of ≥ 20 mg) was used, eligibility rose from 12% to 28% based on both PARADIGM-HF and guidelines. One-year heart failure hospitalization was higher (12% and 17% vs. 12%) and all-cause mortality lower (5.3% and 6.5% vs. 7.7%) in registry eligible patients compared to the enalapril arm of PARADIGM-HF. CONCLUSIONS: Among outpatients with HFrEF in the ESC-EORP-HFA HF-LT Registry, 84% met label criteria, while only 12% and 28% met PARADIGM-HF and guideline criteria for LCZ696 if requiring ≥ 20 mg and ≥ 10 mg enalapril, respectively. Registry patients eligible for LCZ696 had greater heart failure hospitalization but lower mortality rates than the PARADIGM-HF enalapril group.

Exercise Training on Locomotion in Patients with Alzheimer's Disease: A Feasibility Study.

BACKGROUND: Although current literature has shown that patients with Alzheimer's disease (AD) have worse locomotion compared with healthy counterparts, no studies have focused on the efficacy of exercise training in improving gait abnormalities including biomechanics and metabolic aspects, in this population. OBJECTIVE: To verify the effectiveness of exercise training (ET) on gait parameters (i.e., speed, step and stride length, single and double support, and energy cost of walking (Cw)) in patients with AD with respect to a standard cognitive treatment (CT). METHODS: In this study, we included a small portion of data belonging to a larger study (ClinicalTrials.gov number, NCT03034746). Patients with AD (Mini-Mental State Examination 22±5) were included in the study. Gait parameters and Cw were assessed at baseline and after 6 months (72 treatment sessions) of treatment. ET included 90 min of aerobic and strength training. CT included 90 min of cognitive stimuli. RESULTS: The 16 patients assigned to ET exhibited significant improvement of Cw (-0.9±0.1 J/kg·m-1), while differences in gait parameters were negligible. The effect on gait parameters were undetectable in the 18 patients assigned to CT (-0.2±0.5 J/kg·m-1). CONCLUSIONS: Data from this study showed that ET program seems effective in improving Cw in patients with AD. Interestingly, the positive effect of ET on Cw was not coupled with ameliorations of patient's gait parameters, suggesting that the gain of metabolic aspects of locomotion were the main factors responsible for this positive result.

Association between Beta1 -Adrenergic Receptor Polymorphism and Risk of ICD Shock in Heart Failure Patients.

BACKGROUND: Sympathetic activation in heart failure patients favors the development of ventricular arrhythmias, thus leading to an increased risk of sudden cardiac death. ß1 - and ß2 -adrenergic receptor polymorphisms have been linked to the risk of sudden death. Implantable cardioverter-defibrillators (ICD) are implanted in a large percentage of heart failure patients, and beyond preventing sudden cardiac death they provide a continuous monitoring of major ventricular arrhythmias and of their own interventions. We investigated whether functionally relevant ß1 - and ß2 -adrenergic receptor polymorphisms are associated with risk of ICD shocks, as evidenced in ICD memory. METHODS: 311 patients with systolic heart failure were enrolled, and number and timing of shocks in ICD memory were recorded. Four selected polymorphisms were determined: ß1 -adrenergic receptor polymorphisms Ser(49) Gly and Arg(389) Gly and ß2 -adrenergic receptor polymorphisms Arg(16) Gly and Gln(27) Glu. RESULTS: Only Ser(49) Gly was significantly correlated with time free from ICD shocks, both considering time to the first event in a Cox model (hazard ratio 2.117), and modeling repeated events with the Andersen-Gill method (hazard ratio 2.088). Gly allele carriers had a higher probability of ICD shock. The relationship remained significant even after adjusting for ejection fraction and beta-blocker dosage (hazard ratio 1.910). CONCLUSIONS: Data from our study suggest that the ß adrenoreceptor Gly 49 allele of the ß1 -adrenergic receptor Ser(49) Gly polymorphisms may increase the risk of ICD shock in patients with heart failure, independent of beta-blocker dosage.

Dynamic changes of repolarization abnormalities in takotsubo cardiomyopathy.

OBJECTIVE: This study analyses dynamicchangesin dispersion of ventricularrepolarization over the time course of takotsubo cardiomyopathy (TC), and their relationships with clinical features and life-threatening arrhythmias. METHODS AND RESULTS: All consecutive patients admitted to our division between January 2008 and December 2011 with a diagnosis of TC were analysed. Patients with prior myocardial infarction, symptoms-onset-to-admission time greater than 12 hours, an implanted pacemaker, or under treatment with drugs affecting QTinterval, were excluded. Standard 12-lead ECG recordings during the acute, subacute and chronic phases were collected for each patient. Twenty-four patients (23 women, 63 +/- 14 years) were includedin our analysis. Only one patient experienced ventricular arrhythmias (4.2%). Significant increases were observed in QT and QTc intervals (from 420 ?423 to 505 +/- 66 ms, P < 0.00001, and from 479 +/- 33 to 551 +/- 51 ms, P < 0.00001, respectively), QTdispersion (from 59 +/- 18 to 100 +/- 44 ms, P=0.0006), Tpeak-to-Tend (from 82 +/- 20 to 123 +/- 39 ms, P=0.00006) and Tpeak-to-Tend/QT (from 0.20 +/- 0.33 to 0.26 +/- 0.57, P=0.0003) during the subacute phase. All these parameters returned to baseline values in the chronic phase and did not show any significant differences between the acute and chronic phases. CONCLUSIONS: A marked increase in QTc, QT dispersion, Tpeak-to-Tend and Tpeak-to-Tend/QT was observed during the subacute phase; this increase was transient and reverted in allpatients before hospital discharge. Ofnote, these findings were not associated with an increased risk of life-threatening arrhythmias.

Identification of high-risk chronic heart failure patients in clinical practice: role of changes in left ventricular function.

BACKGROUND: Left ventricular (LV) dysfunction and remodeling are key pathophysiological features underlying disease progression in chronic heart failure (CHF). HYPOTHESIS: To describe the course of LV dysfunction and identify predictors and prognostic impact of changes in LV volumes and function in stable CHF patients under optimal therapy. METHODS: There were 318 consecutive CHF outpatients who underwent a repeated echocardiographic evaluation at baseline and at 1 year and subsequently followed-up for at least 12 months. The end point of the study was all-cause mortality. RESULTS: Mean LV ejection fraction (LVEF) was 33 ± 7% at baseline and 36 ± 9% at follow-up. Twenty-four percent of patients had an improvement of LVEF >5 absolute points (group 1); 58% remained stable (group 2), 17% worsened at >5 absolute points (group 3). Age, New York Heart Association class, diuretic dose, renal function, and baseline LVEF were independent predictors of LVEF improvement at 1 year. At the Cox analysis, patients in group 3 had a 4-fold higher risk of death when compared with group 1 (hazard ratio: 3.99, 95% confidence interval: 1.6-9.9, P = 0.002), independently of age, etiology, and symptoms severity. CONCLUSIONS: In stable CHF outpatients, LV function improves in 24% of cases; a modest decrease in LV systolic function is associated with a significantly higher risk of all-cause mortality, independent of other markers of disease severity.

Immunosuppressive therapy with oral prednisone to prevent restenosis after PCI. A multicenter randomized trial.

BACKGROUND: Prednisone at immunosuppressive doses after stenting has shown remarkable efficacy in reducing ischemic recurrences in nondiabetic patients with high post-procedural levels of C-reactive protein; the study aim was to compare the clinical outcome obtained in a control group of patients treated with bare metal stents versus 2 other study groups--bare metal stent plus oral prednisone or drug eluting stents--assuming similar optimal adjunctive medical treatment. METHODS: Five tertiary Italian hospitals enrolled 375 nondiabetic patients with coronary artery disease and no contraindications to dual antiplatelet treatment or corticosteroid therapy in a randomized, controlled study performed between 2007 and 2009. Patients were allocated into 3 study groups: bare metal stents (controls), bare metal stents followed by a 40-day prednisone treatment, or drug-eluting stents. The primary endpoint was the event-free survival of cardiovascular death, myocardial infarction, and recurrence of ischemia needing repeated target vessel revascularization at 1 year as adjudicated by an independent clinical events committee. RESULTS: One-year follow-up was obtained in all patients. Patients receiving bare metal stents alone as compared to those treated with prednisone or drug-eluting stents had lower event-free survival; the primary endpoint was 80.8% in controls compared to 88.0% in the prednisone and 88.8% in the drug-eluting stent groups, respectively (P=.04 and .006). CONCLUSION: Compared with bare metal stents alone, prednisone treatment after bare metal stents or drug-eluting stent implantation result in a better event-free survival at 1 year.

Injury risk factors in young soccer players detected by a multivariate survival model.

Soccer is a popular game practiced all around the world by teenagers. However, despite being a relatively safe sport, muscle-strain injuries during competitive matches are common compared to other team-sports. Few studies, to date, have investigated risk factors for soccer injuries using a multivariate survival model (e.g., Cox regression). The aim of this study was to use a multivariate survival model to investigate factors associated with an increased risk of thigh muscle strains, in young soccer players. A multivariate Cox regression was used to evaluate survival probability predictors for thigh muscle strains. 84 young male soccer players (16.4 ± 1.6 years) were followed for a season. Baseline tests were performed for body size, body composition, endurance, flexibility, and jump height from both a static position (SJ), and with a countermovement (CMJ); the percentage difference between the two types of jumps was also calculated (ΔJH). Cox regression result (hazard ratio; C.I. 95%) showed that: previous injuries (2.80; 1.19-6.54), ΔJH (0.79; 0.71-0.87), and stature (1.17; 1.06-1.25) were significantly correlated to thigh-strain survival probability. This study confirms that previous injuries are an important risk factor. However, we also report that a negative ΔJH and an elevated stature increased the probability of thigh strain. This could be explained by poor player coordination, influencing jumping ability, which may be even more evident in tall young players.

An interactive computer program can effectively educate potential users of cystic fibrosis carrier tests.

The demand for cystic fibrosis (CF) carrier testing is steadily growing, not only from individuals with raised a priori carrier risk, but also from the general population. This trend will likely exceed the availability of genetic counselors, making it impossible to provide standard face-to-face genetic counseling to all those asking for the test. In order to reduce the time needed to educate individuals on the basics of the disease, its genetic transmission, and carrier testing peculiarities, we developed an educational method based on an interactive computer program (IC). To assess the effectiveness of this program and to compare it to a classical genetic counseling session, we conducted a comparative trial. In a population setting of people undergoing assisted reproduction, 44 individuals were randomly assigned to either receiving standard one-on-one genetic counseling or education by the IC program. We measured pre- and post-intervention knowledge about CF genetic transmission and carrier testing. Starting from an equivalent baseline of correct answers to a specially designed multiple-choice questionnaire (47% in the counselor group and 45% in the computer group) both groups showed a highly significant and similar increase (reaching 84% in the counselor group and 85% in the computer group). The computer program under evaluation can successfully educate individuals considering genetic testing for CF.

Cardiovascular and noncardiovascular comorbidities in patients with chronic heart failure.

A broad spectrum of concomitant disorders may complicate heart failure adding further morbidity and mortality risk. Comorbidities may be subdivided into cardiovascular and noncardiovascular. The first group includes hypertension, coronary artery disease, peripheral artery disease, cerebrovascular disease, arrhythmias and valvular heart disease. Noncardiovascular comorbidities include respiratory, endocrine, metabolic, nutritional, renal, hematopoietic, neurological as well as musculoskeletal conditions. In recent years, advances in the treatment of heart failure have not been attended by important changes in management of its comorbidities. They now seem to be major causes of the poor prognosis of heart failure patients. In this review we provide an updated summary of the epidemiological, pathophysiological and clinical characteristics of comorbidities as well as their potential impact for heart failure treatment.

Physiopathologic correlates of intrathoracic impedance in chronic heart failure patients.

BACKGROUND: Increased plasma levels of amino-terminal fraction of brain natriuretic peptide (NT-proBNP) and alterations of diastolic filling as described by Doppler transmitral flow pattern are well-known markers of decompensated heart failure (HF). Recently, some implantable defibrillators have allowed monitoring of intrathoracic impedance, which is related to lung water content, potentially indicating HF deterioration. The aim of this study was to assess the correlation between intrathoracic impedance and NT-proBNP and echo-Doppler transmitral flow indexes. METHODS: Data were collected from 111 HF patients, in six Italian centers. All patients were on optimal medical therapy. Device diagnostics, echographic data, NT-proBNP determination, and clinical status as assessed by the Heart Failure Score (HFS) were registered at baseline, at bimonthly visits, and at unscheduled examinations due to HF decompensation or device alerts. RESULTS: Over a median follow-up of 413 days, 955 examinations were performed. Intrathoracic impedance was significantly correlated with NT-proBNP (P = 0.013) and with mitral E-wave deceleration time (DtE) (P = 0.017), but not with HFS. At the time of confirmed alert events, NT-proBNP was significantly higher than during confirmed nonalert event examinations; DtE did not differ, whereas impedance was significantly lower. CONCLUSION: A decrease in intrathoracic impedance is inversely correlated with NT-proBNP and directly correlated with DtE. Intrathoracic impedance monitoring therefore has the physiologic basis for being a useful tool to identify early HF decompensation.

[Nonvalvular atrial fibrillation: thromboembolic risk assessment and therapy in a general practice population]. / Fibrillazione atriale non valvolare: valutazione del rischio tromboembolico e del trattamento antitrombotico in una popolazione di pazienti in medicina generale.

BACKGROUND: Cardiologists may prescribe antithrombotic therapy to patients with atrial fibrillation (AF), but prescription application mostly depends on general practitioners. The present study aims to assess frequency and appropriateness of antithrombotic therapy in general practice, as a function of thromboembolic risk factors, using the CHADS2 score. METHODS: The computer records of 39 general practitioners were evaluated in order to identify patients with non-valvular AF; therapy and thromboembolic risk factors were recorded. RESULTS: AF was documented in 951 patients; 96 (10.1%) had contraindications to oral anticoagulants. Among the remaining 850 patients, 292 (34.4%) did not receive antithrombotic therapy according to guidelines. In particular, 102 (12.0%) did not receive any antithrombotic treatment. CONCLUSIONS: Among general practitioners of the Veneto region (Italy), the application of guidelines on antithrombotic therapy in non-valvular AF is comparable, or even slightly better than that reported in published cohort studies, but it deserves further improvement. There is a need for targeted educational interventions and a better coordination between cardiologists and general practitioners.

Sleep disordered breathing is associated with appropriate implantable cardioverter defibrillator therapy in congestive heart failure patients.

BACKGROUND: Implantable cardioverter defibrillators (ICDs) are increasingly employed in patients affected by congestive heart failure (CHF) and sleep disordered breathing (SDB) is frequent in this population. HYPOTHESIS: To investigate SDB prevalence and influence on appropriate ICD discharges in CHF patients. METHODS: A total of 22 consecutive ICD patients with systolic CHF (left ventricular ejection fraction [LVEF]< 45%) were studied by polysomnography. RESULTS: A total of 17 (77.2%) showed SDB (apnea-hypopnea index [AHI]_ 10 events/hour). After controlling for LVEF and New York Heart Association (NYHA) class, AHI and severity of hypoxia during sleep results correlated to appropriate ICD discharges (r = 0.718; P < .001, r = - 0.619; P = .003, respectively). CONCLUSIONS: Sleep disordered breathing is frequent in ICD recipients due to left systolic ventricular dysfunction and may increase the risk of ventricular arrhythmia and appropriate ICD discharges.

Inconclusive cystic fibrosis neonatal screening results: long-term psychosocial effects on parents.

AIM: Cystic Fibrosis (CF) Newborn Screening occasionally identifies neonates where a CF diagnosis can neither be confirmed nor excluded. To assess how parents of these infants cope with this ambiguous situation. METHODS: Parents of 11 children with Ambiguous Diagnosis (group AD) were compared with parents of 11 children diagnosed with CF through neonatal screening [group Cystic Fibrosis Diagnosis (CFD)] and with parents of 11 Healthy Control children (group HC) matched for gender and age. RESULTS: The emotional reaction to the inconclusive result was less pronounced in AD than in CFD (p = 0.003), and AD parents considered their infants as healthy as controls. Parents' anxiety about their child's health is stronger in CFD than in AD (p < 0.05) and HC (p < 0.001). Long-term emotional distress was rated similarly in AD and CFD, and greater than in HC (p = 0.0003). The parent/child relationship was less influenced in AD than in the CF group (p = 0.03). Seven AD and CFD parents changed their family planning projects. CONCLUSION: Inconclusive neonatal screening results appear to be understood and associated with lower anxiety levels than CF diagnosis. Concern about the child's health is similar to healthy controls and lower than in parents of CF children.

Usefulness of ultrasonographic markers of carotid atherosclerosis (intima-media thickness, unstable carotid plaques and severe carotid stenosis) for predicting presence and extent of coronary artery disease.

OBJECTIVE: To investigate the usefulness of carotid ultrasound evaluation in predicting the presence and the extent of coronary artery disease in a consecutive series of patients. DESIGN: We examined retrospectively 1337 patients in whom both coronary angiography and carotid ultrasound were evaluated, from 1995 to 2005. Markers of carotid artery disease were considered, such as intima-media thickness more than 0.90 mm, unstable plaque and severe stenosis (> or =70%). Carotid risk score was defined as the sum of these parameters. We considered as affected by significant coronary artery disease those patients with at least one lesion more than 50% within the main branches of the coronary arteries. RESULTS: The markers of carotid atherosclerosis increased proportionally in patients with one-, two- or three-vessel coronary artery disease. At univariate analysis, intima-media thickness more than 0.90 mm was associated with an odds ratio of coronary artery disease of 2.28 (1.8-2.9) (P < 0.0001), unstable plaque 3.6 (2.3-5.7) (P < 0.001) and severe carotid stenosis 4.2 (2.0-8.7) (P = 0.0001). At multivariate analysis, the three markers mentioned above were independent risk factors for coronary artery disease even when considering other risk factors. CONCLUSION: We confirmed the usefulness of carotid ultrasound evaluation in predicting the presence and extent of coronary artery disease. Considering the high correlation between carotid and coronary artery disease, carotid screening is useful in patients with coronary artery disease. In patients with an occasional finding of a carotid risk score of at least 2, a careful search for coronary artery disease seems warranted.

Periprocedural management and in-hospital outcome of patients with indication for oral anticoagulation undergoing coronary artery stenting.

PURPOSE: In patients on oral anticoagulation (OAC) undergoing coronary stenting (PCI-S), procedural management and in-hospital outcome have never been specifically and prospectively investigated. Also, the contribution of early bleeding to the relevant hemorrhagic rate reported at follow-up with triple therapy of OAC, aspirin, and clopidogrel is largely unknown. METHODS: Consecutive patients with indication for OAC undergoing PCI-S at 5 centers were enrolled and prospectively evaluated. RESULTS: Out of 3410 patients undergoing PCI-S in the study period, indication for OAC was present in 4.8%. Femoral approach and bare metal stents were the most frequently used. During PCI-S, OAC was continued in about 30% of patients, whereas in about 20% heparin bridging was carried out. Glycoprotein IIb/IIIa inhibitors were rarely used (11%), whereas a standard bolus of unfractionated heparin was given in 93% of cases. Major adverse cardiovascular events (MACE) occurred in 4.8% of patients and major bleeding in 4.3%. No predictors of MACE or bleeding were identified, although the femoral approach was of borderline significance for major bleeding (OR 4.6, 95% CI 1.0-20.8; P = 0.05). A history of previous hemorrhage (OR 5.3, 95% CI 1.6-18.1; P = 0.007) predicted Carbofilm-coated stent implantation. CONCLUSIONS: A limited, albeit clinically relevant, proportion of patients undergoing PCI-S has indication for OAC. Procedural management appears not substantially different from that of common patients. In-hospital major bleeding is relevant and should be taken into account when evaluating the overall hemorrhagic rate at a medium- to long-term follow-up.
