The Unique Clinical Features and Outcome of Infectious Endocarditis and Vertebral Osteomyelitis Co-infection

Objective

The clinical significance of vertebral osteomyelitis and infectious endocarditis co-infection is unclear. This study investigates the rate, clinical features, and outcome of vertebral osteomyelitis with and without concomitant infectious endocarditis.

Methods

A retrospective study of all cases of osteomyelitis with spinal imaging (n = 176), from January 2007 to April 2013, that were diagnosed as vertebral osteomyelitis. Sixty-two patients with spontaneous vertebral osteomyelitis were identified after excluding postsurgical, decubitus ulcers and spinal metastases. Seventeen (27%) were identified with concomitant infectious endocarditis.

Results

All patients presented with back pain and 59% were diagnosed with infectious endocarditis subsequent to vertebral osteomyelitis. Distinguishing features among the co-infection group include the increased use of transesophageal echocardiography (94% vs 58%, P = .004), predisposing cardiac conditions (59% vs 16%, P = .001), and Gram-positive bacteremia, of which Streptococcus sp. and Enterococcus sp. were more common (35% vs 11%, P = .026). Adverse neurologic events were increased significantly in the co-infection group (59% vs 22%, P = .006). On transesophageal echocardiography, 88% of co-infection patients had highly mobile vegetations, 9 of which measured 10 mm or more. The overall mortality was 41% and 29% in the co-infection and lone vertebral osteomyelitis groups, respectively (P = .356). One-year mortality was identical for both groups at 24% (P = .999), and higher than previously reported (11.3% for lone vertebral osteomyelitis).

Conclusions

Patients with vertebral osteomyelitis, in whom infectious endocarditis is not excluded, are at increased risk for adverse neurologic events and mortality. The prompt diagnosis of infectious endocarditis, and associated high-risk features that may benefit from surgical intervention, require early evaluation by transesophageal echocardiography.     

Percutaneous Aortic Balloon Valvotomy in the United States: A 13-Year Perspective

Background

We determined the contemporary trends of percutaneous aortic balloon valvotomy and its outcomes using the nation's largest hospitalization database. There has been a resurgence in the use of percutaneous aortic balloon valvotomy in patients at high surgical risk because of the development of less-invasive endovascular therapies.

Methods

This is a cross-sectional study with time trends using the Nationwide Inpatient Sample database between the years 1998 and 2010. We identified patients using the International Classification of Diseases, 9th Revision, Clinical Modification procedure code for valvotomy. Only patients aged more than 60 years with aortic stenosis were included. Primary outcome included in-hospital mortality, and secondary outcomes included procedural complications and length of hospital stay.

Results

A total of 2127 percutaneous aortic balloon valvotomies (weighted n = 10,640) were analyzed. The use rate of percutaneous aortic balloon valvotomy increased by 158% from 12 percutaneous aortic balloon valvotomies per million elderly patients in 1998-1999 to 31 percutaneous aortic balloon valvotomies per million elderly patients in 2009-2010 in the United States (P < .001). The hospital mortality decreased by 23% from 11.5% in 1998-1999 to 8.8% in 2009-2010 (P < .001). Significant predictors of in-hospital mortality were the presence of increasing comorbidities (P = .03), unstable patient (P < .001), any complication (P < .001), and weekend admission (P = .008), whereas increasing operator volume was associated with significantly reduced mortality (P = .03). Patients who were admitted to hospitals with the highest procedure volume and the highest volume operators had a 51% reduced likelihood (P = .05) of in-hospital mortality when compared with those in hospitals with the lowest procedure volume and lowest volume operators.

Conclusion

This study comprehensively evaluates trends for percutaneous aortic balloon valvotomy in the United States and demonstrates the significance of operator and hospital volume on outcomes.     

Thrombocytopenia,Dual Antiplatelet Therapy,and Heparin Bridging Strategy Increase Pocket Hematoma Complications in Patients Undergoing Cardiac Rhythm Device Implantation

Background

Pocket hematoma is a troublesome complication associated with the implantation of cardiac implantable electronic devices (CIEDs). This study aims to determinate the risk factors of pocket hematoma complications in relation to different antithrombotic strategies and severity of thrombocytopenia in Chinese patients.

Methods

We conducted a retrospective study of 1093 consecutive patients undergoing implantation of CIEDs and divided them into 3 groups: no antithrombotic group (n = 512), continuing antiplatelet group (n = 477), and temporarily discontinuing warfarin with or without heparin bridging strategy (n = 104).

Results

A pocket hematoma developed in 40 patients (3.7%). The temporarily discontinuing warfarin group (7.7%) had a higher incidence of pocket hematoma than no oral antithrombotic group (2.1%) and continuing antiplatelet group (4.4%) (P = 0.012). The dual antiplatelet group (16.2%) and the heparin bridging strategy group (14.0%) had significantly higher incidence of pocket hematoma compared with the no antithrombotic group (2.1%; P < 0.001, both). Patients having aspirin or clopidogrel alone had low incidence of pocket hematoma (3.9% and 1.2%, respectively), similar to the no antithrombotic group (P = not significant). Multivariate analysis revealed that dual antiplatelet agents (P = 0.004), heparin bridging strategy (P < 0.001), and moderate to severe thrombocytopenia (P = 0.007) were independent predictors for pocket hematoma complications.

Conclusions

The use of dual antiplatelet agents, heparin bridging strategy, and the presence of moderate to severe thrombocytopenia significantly increased the risk of pocket hematoma complications in the periprocedural period of CIED implant. Aspirin or clopidogrel alone did not increase the risk of pocket hematoma complications.     

Corrélations entre antécédents d’angioplastie coronaire et mortalité précoce après chirurgie coronaire

Background

In this study, we examine the effect of previous percutaneous intervention on the rate of adverse perioperative outcome in patients undergoing coronary artery bypass graft surgery (CABG).

Methods

Outcomes of 240 CABG patients, collected consecutively in an observational study, were compared. Gp A (n = 35) had prior PCI before CABG and Gp B (n = 205) underwent primary CABG.

Results

Statistically significant results were obtained for the following preoperative criteria: previous myocardial infarction: 48.6% vs 36.6% (P = 0.003), distribution of CAD (P = 0.0001), unstable angina: 45.7% vs 39% (P = 0.04). For intraoperative data, the total number of established bypasses was 2.6 (GpA) vs 2.07 (Gp B) (P = 0.017), with the number of arterial bypass grafts being: 20% vs 13% (P = ns). Regarding the postoperative course, no significant difference in troponine I rate, 24-hour bleeding: 962 ml (Gp A) vs 798 ml (Gp B) (P = 0.004), transfusion (PRBC unit): 3.63 (Gp A) vs 2.5 (Gp B) (P = 0.006). Previous PCI emerged as an independent predictor of postoperative in-hospital mortality (OR 2.24, 95% CI [1.52–2.75], P < 0.01).

Conclusion

Patients with prior PCI presented for CABG with more severe CAD. Thirty-day mortality and morbidity were significantly higher in patients with prior PCI.     

Non-high-density lipoprotein cholesterol and the development of coronary heart disease and stroke subtypes in a general Japanese population: The Hisayama Study

Background and purpose

It has not been fully determined whether non-high-density lipoprotein cholesterol (non-HDLC) levels are involved in vascular events, especially stroke, in general Asian populations. We evaluated the association between non-HDLC levels and the risk of type-specific cardiovascular disease in a prospective cohort study in Japan.

Methods

A total of 2452 community-dwelling Japanese subjects aged ≥40 years were followed prospectively for 24 years.

Results

The age- and sex-adjusted incidence of coronary heart diseases (CHD) significantly increased with elevating non-HDLC levels (P for trend < 0.001), but no such association was observed for ischemic and hemorrhagic strokes. With regard to ischemic stroke subtypes, the age- and sex-adjusted incidence of lacunar infarction significantly increased with elevating non-HDLC levels (P for trend < 0.01), and such tendency was seen for atherothrombotic infarction (P for trend = 0.098), while a significant inverse association was observed for cardioembolic infarction (P for trend = 0.007). After adjustment for confounders, namely, age, sex, diabetes, body mass index, systolic blood pressure, electrocardiogram abnormalities, current drinking, current smoking, and regular exercise, the associations remained significant for CHD [adjusted hazard ratio (HR) for a 1 standard deviation of non-HDLC concentrations = 1.17, 95% confidence interval (CI) = 1.02 to 1.35], atherothrombotic infarction (adjusted HR = 1.39, 95% CI = 1.09 to 1.79), and cardioembolic infarction (adjusted HR = 0.64, 95% CI = 0.47 to 0.85).

Conclusions

Our findings suggest that elevated non-HDLC levels are a significant risk factor for the development of atherothrombotic infarction as well as CHD but reduce the risk of cardioembolic infarction in the general Japanese population.     

Increased Prevalence of Coronary Artery Disease in Severe Psoriasis and Severe Atopic Dermatitis

Background

Psoriasis and atopic dermatitis (AD) are immuno-inflammatory diseases that can result in lifelong systemic inflammation. Unlike AD, psoriasis has been associated with cardiovascular disease. The aim of this study was to examine the prevalence, severity, and subtype of coronary artery disease (CAD) in psoriasis and AD patients without known cardiovascular disease.

Methods

Consecutively enrolled patients (psoriasis n = 58, AD n = 31) and retrospectively matched controls (n = 33) were examined using cardiac computed tomography angiography (CCTA) and assessed using an 18-segment model of the coronary tree.

Results

The prevalence of a coronary artery calcium score >0 was 29.8% in psoriasis and 45.2% in AD, vs 15.2% in controls (P = .09 and P = .01, respectively). More patients with psoriasis had a coronary artery calcium score ≥100 (psoriasis 19.3%, controls 2.9%; P = .02). CCTA showed the presence of plaques in 38.2% of psoriasis patients and 48.1% of AD patients, vs 21.2% of controls (P = .08 and P = .03, respectively). Psoriasis was associated with an increased prevalence of significant coronary stenosis (stenosis >70%) (psoriasis 14.6%, controls 0%; P = .02) and 3-vessel coronary affection or left main artery disease (psoriasis 20%, controls 3%; P = .02), whereas AD was associated with mild (AD 40.7%, controls 9.1%; P = .005) single-vessel affection.

Conclusions

These findings suggest that psoriasis and AD are associated with an increased prevalence of CAD. Patients with psoriasis have an increased prevalence of severe CAD.     

Lower Blood Vitamin D Levels Are Associated With an Increased Incidence of Contrast-Induced Nephropathy in Patients Undergoing Coronary Angiography

Background

Vitamin D deficiency may be associated with an increased risk of renovascular disease. We assessed the correlation between vitamin D levels and contrast-induced nephropathy (CIN) in patients undergoing coronary angiography (CAG).

Methods

Vitamin D and parathyroid hormone (PTH) levels were assessed before CAG in 403 patients. Estimated glomerular filtration rate (eGFR) was calculated using the Cockcroft-Gault equation. Patients with eGFR < 60 mL/min/1.73 m² were hydrated with 0.9%-saline at 1 mL/kg/h for 12 hours before and after CAG. CIN was defined as serum creatinine increase of > 0.5 mg/dL or > 25% within 48-72 hours after CAG.

Results

CIN developed in 74 participants. Baseline eGFR, blood urea and creatinine in CIN (+) and (−) groups were not significantly different (P = 0.14, P = 0.07, and P = 0.61, respectively). Total volume of contrast medium (CM) was higher in the CIN (+) group (132 ± 64 mL vs 90 ± 41 mL; P = 0.01). Vitamin D levels were lower (median 8.5 [range, 0.5-26.6] ng/mL vs 14.9 [range, 1.9-93.5] ng/mL; P = 0.01) and PTH levels were higher (median 73.9 [range, 22-530] pg/mL vs 44.2 [range, 5-361] pg/mL; P = 0.01) in the CIN (+) group. Multivariate logistic regression analysis revealed that lower vitamin D levels (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.11-1.26; P = 0.01) and increased CM volume (OR, 1.01; 95% CI, 1.008-1.017; P = 0.01) were independently correlated with CIN. In patients who had undergone percutaneous coronary intervention, lower levels of vitamin D were independently associated with CIN development.

Conclusions

Lower vitamin D levels, implying possible vitamin D deficiency, are associated with a higher incidence of CIN.     

Randomized Trial of Nordic Walking in Patients With Moderate to Severe Heart Failure

Background

Patients with heart failure are a growing population within cardiac rehabilitation. The purpose of this study was to compare, through a single-centre, parallel-group, randomized controlled trial, the effects of Nordic walking and standard cardiac rehabilitation care on functional capacity and other outcomes in patients with moderate to severe heart failure.

Methods

Between 2008 and 2009, 54 patients (aged 62.4 ± 11.4 years) with heart failure (mean ejection fraction = 26.9% ± 5.0%) were randomly assigned to standard cardiac rehabilitation care (n = 27) or Nordic walking (n = 27); both groups performed 200 to 400 minutes of exercise per week for 12 weeks. The primary outcome, measured after 12 weeks, was functional capacity assessed by a 6-minute walk test (6MWT).

Results

Compared with standard care, Nordic walking led to higher functional capacity (Δ 125.6 ± 59.4 m vs Δ 57.0 ± 71.3 m travelled during 6MWT; P = 0.001), greater self-reported physical activity (Δ 158.5 ± 118.5 minutes vs Δ 155.5 ± 125.6 minutes; P = 0.049), increased right grip strength (Δ 2.3 ± 3.5 kg vs Δ 0.3 ± 3.1 kg; P = 0.026), and fewer depressive symptoms (Hospital Anxiety and Depression Scale score = Δ −1.7 ± 2.4 vs Δ −0.8 ± 3.1; P = 0.014). No significant differences were found for peak aerobic capacity, left-hand grip strength, body weight, waist circumference, or symptoms of anxiety.

Conclusions

Nordic walking was superior to standard cardiac rehabilitation care in improving functional capacity and other important outcomes in patients with heart failure. This exercise modality is a promising alternative for this population.     

Endocarditis infecciosa en 2 hospitales universitarios españoles que difieren en su localización y en la presencia de servicio quirúrgico

Objectives

To assess possible differences in clinical presentation, microbiology, morbidity and mortality of infective endocarditis between two Spanish hospitals, one on the mainland that has cardiac surgery and one in the Canary Islands without this service.

Method

A total of 229 patients consecutively diagnosed of endocarditis between 2005 and 2012, including pediatric population, were studied in the Reina Sofía Hospital (Córdoba, n = 119) and Nuestra Señora de Candelaria Hospital (Tenerife, n = 110). We compared the clinical, microbiological and echocardiographic data and analyzed mortality differences by binary logistic regression analysis.

Results

There were no differences in underlying heart disease, proportion of surgery, or the microbiological profile. The proportion of infections attributable to catheter was higher in the Canary Islands hospital (13.6% vs 3.4%). Mortality was also higher (31.8% vs 18.5%, P = .020), although this difference was no longer significant in the multivariate analysis (OR = 1.85; 95% CI, 0.70-4.87; P = .213). Age (OR = 1.04/year; 95% CI, 1.01-1.07; P = .006), cardiac complications (OR = 5.05; 95% CI, 1.78-14.34; P = .002), persistent sepsis (OR = 4.89; 95% CI, 2.09-11.46; P < .001), and emergent surgery (OR = 4.43, 95% CI, 1.75-11.19; P = .002) were independent predictors of death. Time to surgery, length of stay in the hospital without a surgical service (20 [13-30.5] vs 13 [6-25] days; P = .019) was not associated with outcome.

Conclusions

There are differences in the presentation of endocarditis between two distant hospitals in Spain. The different hospital mortality can not be directly related to the presence of a surgery service.     

Résultats diagnostiques à court terme et pronostiques à long terme chez des patients avec syncopes inexpliquées : résultats d’un série menée en centre hospitalier

Objective

Evaluate the diagnostic and prognostic input of head-up tilt test in the exploration of unexplained syncope.

Method

Between January 2009 and December 2012, all patients undergoing a head-up tilt test for recurrent syncope were studied. Follow-up data were obtained using telephone interviews and medical record reviews.

Results

A head-up tilt test was realized in 77 patients (47.8 ± 20 years, 53% female) for an exploration of syncope. The tilt test elicited syncope or pre-syncope in 57 patients (74%). The positive response included vaso-vagal syncope in 53 patients and psychogenic syncope in 4 patients. After a mean follow-up of 32 ± 11 months (range 6–54 months), 90% of patients had not a recurrence of syncope. Of note, the incidence of recurrence was the same regardless of whether the patients had a positive (n = 5/48; 10%) or a negative head-up tilt test response (n = 2/19; 10%).

Conclusion

The tilt test has a certain diagnostic value in the exploration of unexplained syncope. Recurrence rate of syncope after a tilt test is low. However, our study suggests no correlation between head-up tilt test results and the likelihood of recurring syncope.     

Influencia del fenómeno migratorio sobre la tuberculosis en una zona semiurbana

Aims

To describe the epidemiology of tuberculosis and analyzing the differences among native and immigrant patients in Area III of the Region of Murcia.

Methods

Cohort study of tuberculosis cases reported to the Epidemiological Surveillance Service from 2004 to 2009. Data collection was performed through the System of Notification Diseases, reviewing clinical files and epidemiological surveys.

Results

One hundred sixty two cases were detected; 110 (67.9%) were immigrants, whose incidence rates ranged from 43.4 to 101.2 cases per 100,000 inhabitants. Ecuador (42.7%), Bolivia (30%) and Morocco (18.2%) were the main nationalities.Immigrants were younger than Spanish population (P < .001). The overall diagnostic delay was 50.5 days: 59.5 in Spanish and 47 in foreigners. Moroccans had higher proportions of extrapulmonary TB (P = .02). Mainly, immigrant population took treatment with four drugs (P < .001). Natives had better treatment adherence (P = .04). Spanish cases tuberculosis were associated with smoking (P < .001), the same as alcohol consumption (P = .01) and injection drug use (P < .001), nevertheless in the foreign-born population the most relevant risk factor was overcrowding (P < .001).

Conclusions

The incidence tuberculosis rates are higher among immigrant population, whose the main risk factor is overcrowding. In contrast, Spanish cases are associated with toxic substances consumption and increasing age.     

Pacemaker-Detected Atrial Fibrillation in Patients With Pacemakers: Prevalence,Predictors, and Current Use of Oral Anticoagulation

Background

Dual-chamber pacemakers frequently document atrial fibrillation (AF) in patients without symptoms. Pacemaker-detected AF is associated with a 2.5-fold increased risk of stroke, although it is not established whether oral anticoagulation reduces this risk. This study sought to determine the prevalence and predictors of pacemaker-detected AF and to document current oral anticoagulant use.

Methods

A retrospective analysis included all patients from a single academic hospital who had pacemakers capable of documenting AF. Blinded evaluation of all echocardiograms conducted within 6 months of implantation was performed.

Results

Of 445 patients, pacemaker-detected AF was present in 246 (55.3%), who were older (74.3 ± 13.7 years vs 71.7 ± 14.4, P = 0.046), more likely to have a history of clinical AF (29.7% vs 19.1%, P = 0.01), and had a larger left atrial volume index (34.4 ± 11.8 mL/m² vs 30.0 ± 9.9 mL/m², P = 0.019) than the patients without pacemaker-detected AF. Among patients without a clinical history of AF, left atrial volume index was higher among those with pacemaker-detected AF (33.7 ± 11.3 mL/m² vs 29.0 ± 10.1 mL/m², P = 0.034). Anticoagulants were used in 35.3% of patients with pacemaker-detected AF, compared with 21.6% of patients without (P < 0.05). In patients with pacemaker-detected AF, anticoagulants were used more frequently among patients who also had clinical AF (58.9%) compared with those without (23.7%, P < 0.001).

Conclusions

Pacemaker-detected AF occurs in 50% of pacemaker patients and is treated with anticoagulants in less than 25% of patients who do not have a history of clinical AF. Clinical trials are needed to determine the role of anticoagulation in this population.     

Late Gadolinium Enhancement in Cardiac Transplant Patients Is Associated With Adverse Ventricular Functional Parameters and Clinical Outcomes

Background

Heart transplant recipients (HTRs) experience multiple cardiac complications, many of which might produce myocardial fibrosis. Cardiovascular magnetic resonance imaging (CMR) can image myocardial fibrosis using late gadolinium enhancement (LGE) imaging. We hypothesized that the presence and volume of LGE in heart transplant recipients correlates with left ventricular (LV) functional parameters and clinical outcomes.

Methods

Thirty-eight stable HTRs underwent a CMR study and clinical follow-up.

Results

In 38 stable HTRs, LGE was seen in 19 patients (50%), of which 15 (79%) had a nonischemic pattern and 4 (21%) had an ischemic pattern. LGE volume was associated with reduced LV ejection fraction (EF) (R² = 0.57; P = 0.001) and increased LV end-diastolic volume (R² = 0.59; P = 0.001). The presence of LGE was associated with cardiovascular death or hospitalization within the next year (P = 0.04), and patients who died or were hospitalized had more LGE than those that were not hospitalized (15 g vs 7 g; P = 0.03).

Conclusions

LGE is common in HTR and is associated with adverse ventricular remodelling and adverse clinical outcomes. LGE might be a useful noninvasive approach to monitor graft disease in asymptomatic patients after heart transplant.     

Caregiving in heart failure: Relationship quality is associated with caregiver benefit finding and caregiver burden

Objective

To determine whether relationship quality is associated with caregiver benefit or burden and how depression influences these associations.

Background

Caregivers influence outcomes of patients with heart failure (HF). Relationship quality, caregiver benefit and burden are key factors in the caregiving experience.

Methods

Nineteen caregivers of HF outpatients completed measures of relationship quality, caregiver benefit, burden and depression. Associations were assessed using Pearson's correlations.

Results

Relationship quality was positively associated with caregiver benefit (r = 0.45, P = 0.05) and negatively associated with burden (r = −0.80, P < 0.0001) and depression (r = −0.77, P = 0.0001). Relationship quality and burden remained associated after controlling for depression.

Conclusions

In this exploratory study, relationship quality was positively associated with caregiver benefit and negatively associated with burden. Future studies are needed to further understand these key caregiving factors, which may lead to opportunities to help caregivers see benefits and reduce burden.     

Association of metabolically abnormal but normal weight (MANW) and metabolically healthy but obese (MHO) individuals with arterial stiffness and carotid atherosclerosis

Objective

Despite recent interest in differential impact of body size phenotypes on cardiovascular outcomes and mortality, studies evaluating the association between body size phenotypes and indicators of atherosclerosis are limited. This study investigated the relationship of metabolically abnormal but normal weight (MANW) and metabolically healthy but obese (MHO) individuals with arterial stiffness and carotid atherosclerosis in Korean adults without cardiovascular disease.

Methods

A total of 1012 participants (575 men and 437 women, mean age 50.8 years), who underwent a health examination between April 2012 and May 2013 were prospectively enrolled based on inclusion and exclusion criteria. Study subjects were classified according to body mass index (BMI) and the presence/absence of metabolic syndrome.

Results

The prevalence of metabolically healthy normal weight (MHNW), MANW, MHO, and metabolically abnormal obese (MAO) were 54.84%, 6.42%, 22.83%, and 15.91%, respectively. Individuals with MANW had significantly higher brachial-ankle pulse wave velocity and maximal carotid intima-media thickness values than those with MHO, after adjusting for age and gender (P = 0.026 and P = 0.018, respectively). The odds ratio (OR) of arterial stiffness and carotid atherosclerosis in the MANW group were significantly higher than in the MHNW group in unadjusted models. Furthermore, multivariable models showed that increased OR of carotid atherosclerosis in the MANW group persisted even after adjusting for confounding factors (OR = 2.98, 95% CI = [1.54, 5.73], P = 0.011).

Conclusions

Compared to MHNW or MHO subjects, Korean men and women with the MANW phenotype exhibited increased arterial stiffness and carotid atherosclerosis.

Weight gain in infancy is associated with carotid extra-medial thickness in later childhood

Objective

Early life is an important period for determining future risk of cardiovascular disease. Carotid extra-medial thickness is a novel noninvasive measure that estimates arterial adventitial thickness, information concerning vascular health not captured by assessment of arterial intima-media thickness alone. We sought to determine whether fetal growth and early postnatal growth are associated with carotid extra-medial thickness in 8 year old children.

Methods

Carotid extra-medial thickness was assessed by high-resolution ultrasound in 379 non-diabetic children aged 8-years, with complete data for birth weight, gestational age, early postnatal weight gain and carotid extra-medial thickness.

Results

Weight gain during infancy, from birth to 18 months of age, was significantly and positively associated with carotid EMT (11 μm per kg length-adjusted weight gain [95% CI 3, 18], P = 0.007). This association was significantly stronger in boys than girls (P_{heterogeneity} = 0.005). By contrast, there was no significant association between birth weight and carotid EMT (6 μm/kg birth weight [95% CI −12, 24], P = 0.51).

Conclusion

Excessive weight gain during infancy is associated with increased carotid extra-medial thickness, indicating that the alterations to the vasculature associated with excessive early postnatal growth likely include arterial adventitial thickening.     

Influencia de una estrategia de alerta multidisciplinaria en la mortalidad por endocarditis infecciosa izquierda

Introduction and Objectives

Mortality from left-sided infective endocarditis remains very high. The aim of this study was to assess the impact of a multidisciplinary alert strategy (AMULTEI), based on clinical, echocardiographic and microbiological findings, implemented in 2008 in a tertiary hospital.

Methods

Cohort study comparing our historical data series (1996-2007) with the number of patients diagnosed with left-sided endocarditis from 2008-2011 (AMULTEI).

Results

The AMULTEI cohort included 72 patients who were compared with 155 patients in the historical cohort. AMULTEI patients were significantly older (62.5 vs 57.9 years in the historical cohort; P=.047) and had higher comorbidity (Charlson index, 3.33 vs 2.58 in the historical cohort; P=.023). There was also a trend toward more enterococcal etiology in the AMULTEI group (20.8% vs 11.6% in the historical cohort; P=.067). In the AMULTEI group, early surgery was more frequently performed (48.6% vs 23.2%; P<.001) during hospitalization, the incidence of septic shock was significantly lower (9.7% vs 24.5%; P=.009) and there was a trend toward reductions in neurological complications (19.4% vs 29.0%; P=.25) and severe heart failure (12.5% vs 18.7%; P=.24). In-hospital mortality and mortality during the first month of follow-up were significantly lower in the AMULTEI group (16.7% vs 36.1%; P=.003).

Conclusions

Despite the trend toward older age and more comorbidity measured by the Charlson index, early mortality was significantly lower in patients treated with the AMULTEI strategy.Full English text available from:www.revespcardiol.org/en     

Association of borderline ankle-brachial index with mortality and the incidence of peripheral artery disease in diabetic patients

Objective

Peripheral artery disease (PAD) and diabetes mellitus are significant risk factors for all-cause death or cardiovascular death. PAD occurs more frequently in diabetic than in non-diabetic patients. However, the association of ankle-brachial index (ABI), especially borderline ABI, with clinical outcomes has not been fully elucidated in diabetic patients. This study aimed to investigate the association of ABI with mortality and the incidence of PAD in Japanese diabetic patients.

Methods

This observational study included 3981 diabetic patients (61.0 ± 11.8 years of age, 59.4% men), registered in the Kyushu Prevention Study for Atherosclerosis. Patients were divided into 3 groups according to the value of ABI at baseline: ABI ≤0.90 (abnormal ABI:354 patients), 0.91 ≤ ABI ≤ 0.99 (borderline ABI:333 patients), and 1.00 ≤ ABI ≤ 1.40 (normal ABI:3294 patients).

Results

Cumulative incidence of all-cause death was significantly higher in patients with abnormal and borderline ABI than in those with normal ABI (34.4% vs. 13.5%, P < 0.0001 and 26.1% vs. 13.5%, P < 0.0001, respectively). In multivariate analysis, the risks for all-cause death in patients with abnormal ABI (HR:2.16; 95%CI:1.46–3.14; P = 0.0002) and borderline ABI (HR:1.78; 95%CI:1.14–2.70; P = 0.01) were significantly higher than in those with normal ABI. The incidence of PAD was remarkably higher in patients with borderline ABI than in those with normal ABI (32.2% vs.9.6%, P < 0.0001). After adjustment, the risk for PAD was significantly higher in patients with borderline ABI than in those with normal ABI (HR:3.10; 95%CI:1.90–4.95; P < 0.0001).

Conclusions

Borderline ABI in diabetic patients was associated with significantly higher risks for mortality and PAD compared with normal ABI.
