ABSTRACT: BACKGROUND: This study aimed to assess long-term prognosis of stable coronary artery disease (sCAD) in patients aged ≥ 75 years and to identify clinical predictors of cardiovascular and overall mortality. MATERIALS AND METHODS: From February 2000 to January 2007, 391 outpatients aged ≥ 75 years (median 78 years, interquartile range [IQR] 76-81 years, 66% male) with sCAD were recruited in this prospective cohort study. Associations of baseline variables with long-term cardiovascular and all-cause death were investigated. RESULTS: After up to 11 years of follow-up (median 4 years, IQR 2-6 years), 89 patients died (23%, 5·45%/year), 35 from cardiovascular causes (9%, 2·14%/year). Multivariate analysis identified family history of coronary disease (HR 4·28, 95% CI 1·22-15·02, P = 0·02), baseline atrial fibrillation (HR 3·18, 95% CI 1·37-7·39, P = 0·007), age (HR 1·61 per 5 year increase, 95% CI 1·04-2·50, P = 0·03), resting heart rate (HR 1·26 per 5 bpm increase, 95% CI 1·09-1·47, P = 0·003) and previous revascularization (HR 0·17, 95% CI 0·04-0·77, P = 0·02) as independent predictors of cardiovascular death, and previous acute coronary syndrome (HR 4·93, 95% CI 1·49-16·30, P = 0·009), baseline atrial fibrillation (HR 1·96, 95% CI 1·12-3·43, P = 0·02), tobacco use (HR 1·69, 95% CI 1·00-2·84, P = 0·049 for ex-smoking and HR 6·78, 95% CI 0·89-51·47, P = 0·06 for active smoking), age (HR 1·58 per 5 year increase, 95% CI 1·18-2·11, P = 0·002), resting heart rate (HR 1·10 per 5 bpm increase, 95% CI 1·00-1·22, P = 0·05) and diastolic blood pressure (HR 0·97, 95% CI 0·94-0·99, P = 0·01) as independent predictors of overall mortality. CONCLUSIONS: In this study, 4-years overall mortality was 23% among elderly patients with sCAD. Simple clinical variables can identify patients at higher risk of mortality.

ABSTRACT: INTRODUCTION AND OBJECTIVES: Different studies have shown improvement in patients with idiopathic nonischemic dilated cardiomyopathy treated with cell-therapy. However, factors influencing responsiveness are not well known. This trial investigates functional changes and factors influencing the 6-month gain in ejection fraction in 27 patients with dilated cardiomiopathy treated with intracoronary cell-therapy. METHODS: Patients received intracoronary infusion of autologous bone-marrow mononuclear cells (mean infused, 10.2 [2.9]×10(8)). Flow cytometry and functional analyses of the cells were also performed. RESULTS: The 6-month angiographic gain in ejection fraction ranged from -9% to 34% (mean, 9%). These changes were distinguished into 2 groups: 21 patients (78%) with a significant improvement at the 6-month evaluation (mean gain, 14 [7]%), and 6 patients who had no response (mean gain, -5 [3]%). The responders were younger as compared to the nonresponders (50 [12] years vs 62 [9] years; P<.04). There was an inverse correlation (r=-0,41; P<.003) between the gain in ejection fraction and the high density lipoprotein level, suggesting higher functional gain with low high density lipoprotein levels. The 24h migratory capability of the infused cells was significantly reduced in the responders' group (5.4 [1.7]×10(8) vs 8.1 [2.3]×10(8); P<.009 for vascular endothelial growth factor and 5.8 [1.7]×10(8) vs 8.4 [2.9]×10(8); P<.002 for stromal cell-derived factor-1). CONCLUSIONS: Younger patients with dilated cardiomiopathy and lower plasma high density lipoprotein levels gain greater benefit from intracoronary cell-therapy. Functional improvement also seems to be enhanced by a lower migratory capacity of the infused cells. Full English text available from:www.revespcardiol.org/en.

ABSTRACT: The authors' aim was to investigate the prognostic value of first-visit systolic and diastolic blood pressure (SBP/DBP) in hypertensive patients with stable coronary artery disease (sCAD) in conditions of contemporary daily clinical practice. From February 1, 2000, to January 31, 2004, 690 consecutive hypertensive patients with sCAD (mean age 68 ± 10 years, 65% male) were prospectively followed in the outpatient cardiology clinic for major events (acute coronary syndrome, revascularization, stroke, heart failure, or death) and associations with baseline SBP/DBP were investigated. At first visit, median SBP/SDP were 130/75 mm Hg (interquartile range, 25-75; 120-140/70-80 mm Hg). After 25 months of follow-up (median), 19 patients died (2.8%); 10 from cardiovascular causes (1.5%), 87 patients experienced a coronary event (13%), and 130 patients (19%) a major event. After adjusting for baseline variables, DBP <75 mm Hg or SBP <130 mm Hg resulted in independent predictors of major events (hazard ratio [HR], 1.52; 95% confidence interval [CI], 1.07-2.16, P=.02; HR, 1.68; 95% CI, 1.18-2.40, P=.004, respectively), coronary events (HR, 1.78; 95% CI, 1.15-2.75, P=.009; HR, 1.84; 95% CI, 1.20-2.83, P=.005, respectively), and cardiovascular mortality (HR, 7.02; 95% CI, 1.26-39.04, P=.03; HR, 9.26; 95% CI, 1.33-64.32, P=.02, respectively). In this study, a low first-visit SBP or DBP was associated with an adverse prognosis in hypertensive patients with sCAD of contemporary daily clinical practice.

ABSTRACT: The study aim was to investigate the etiologic spectrum of at least moderate mitral regurgitation (MR) in patients at a tertiary care center in a Spanish region.
All patients referred for echocardiography with moderate or severe MR, assessed according to the guidelines of the American Society of Echocardiography, were included prospectively in the study.
Between October 2006 and February 2008, a total of 276 patients (157 females, 119 males; mean age 61 +/- 20 years) were enrolled into the study. At the time of evaluation, 67% of the patients were outpatients and the remainder were hospitalized. The NYHA functional class was III-IV in 31% of patients. The main echocardiographic data were: color flow jet area 11 +/- 5 cm2, vena contracta 6.7 +/- 1.9 mm, effective regurgitant orifice area 0.46 +/- 0.28 cm2, left ventricular diastolic and systolic diameters 58 +/- 10 mm and 39 +/- 12 mm, respectively, left ventricular ejection fraction 0.55 +/- 0.19, and pulmonary artery systolic pressure 39 +/- 16 mmHg. The MR was degenerative in 42% of patients, rheumatic in 22%, functional due to idiopathic dilated cardiomyopathy in 18%, functional due to ischemic cardiomyopathy in 7%, congenital in 7%, and had other causes in 4%.
Among this Spanish population, the majority of the moderate or severe MR encountered was organic, with degenerative mitral disease as the most common etiology. Functional regurgitation was present in a significant proportion of patients, with idiopathic dilated cardiomyopathy being the most frequent cause.

ABSTRACT: Atrial septal defect (ASD) is one of the most common congenital heart diseases. Nowadays, percutaneous closure is considered the treatment of choice in most of secundum ASDs. Assessment of the defect and procedure monitoring have been usually performed by angiographic balloon-sizing and/or two-dimensional (2D) transesophageal echocardiography. However, in complex ASDs these techniques might be inaccurate.
From January 2009 to January 2011 all adult patients with complex ASDs submitted for percutaneous closure were selected. Those defects, where shunts were present through a device previously implanted on the atrial septum or through multiperforated septums, were considered complex ASDs. Two-dimensional transesophageal echocardiography and real time three-dimensional (3D) echocardiography were performed simultaneously during the percutaneous closure procedure. Number of orifices, relationships between the defect, catheter, and device, as well as residual shunt were assessed.
Seven patients were included. Five patients had a multiperforated septum and in two cases the defect in the septum was through a previously implanted device. In all cases, 3D echocardiography was superior to 2D echocardiography in relation to the assessment of the relationship between the defect and the catheter or the device. Mechanisms responsible for residual shunts through a device were also better assessed by 3D echocardiography.
Three-dimensional echocardiography is a safe and useful technique when monitoring percutaneous closure of ASDs, showing relevant advantages over 2D echocardiography.

ABSTRACT: To analyse the ultrasound anatomy of bifurcation lesions {1,1,0},{0,1,0} and {1,0,0} of the Medina classification in order to identify predictors of angiographic side branch (SB) damage after main branch (MB) stenting.
One hundred and ten patients with Medina classification bifurcation lesions of {1,1,0},{0,1,0} and {1,0,0} were recruited. An intravascular ultrasound study (IVUS) was performed on the MB before treatment, after stent implantation and after SB intervention. A quantitative analysis was conducted in combination with a qualitative study of the carina morphology and plaque distribution. Ostial SB damage (an increase of the percentage of ostial stenosis by QCA ≥30%) was observed in 51 lesions (48%) after MB stenting. The baseline IVUS identified a carina with a spiky morphology ("eyebrow" sign) in 51 bifurcations. In 41 out of 51 bifurcations with this sign, ostial SB damage was induced after stenting the MB due to carina shift (p<0.01). Narrower angiographic angles were associated with the presence of the "eyebrow" sign (62º±23º vs. 76º±24º, p<0.05). Plaque located at the carina was associated with a lower rate of ostial SB damage (29%) when compared with those lesions with no plaque exhibiting at the carina (51%), p<0.05.
The "eyebrow" sign is a powerful predictor of ostial SB damage after stent implantation in the MB in bifurcation coronary lesions without plaque involving the SB.

ABSTRACT: Transluminal balloon tearing of the membrane in a thin discrete subaortic stenosis is an alternative to membrane surgical resection. However, the long-term outcome of patients with isolated thin discrete subaortic stenosis treated by transluminal balloon tearing remains unknown.
This 25-year study describes findings from 76 patients with isolated thin discrete subaortic stenosis who underwent percutaneous transluminal balloon tearing of the membrane and were followed up for a mean period of 16±6 years. The age at presentation had a wide range (2-67 years). The mean age at treatment was 19±16 years. Immediately after treatment, the subvalvular gradient decreased from 70±27 to 18±12 mm Hg (P<0.001). No significant postprocedural aortic regurgitation was observed. After a mean follow-up time of 16±6 years, 11 patients (15%) developed restenosis, 3 patients (4%) progressed to muscular obstructive disease, and 1 patient (1.3%) developed a new distant obstructive membrane. Twelve patients (16%) were redilated at a mean of 5±3 years after their first treatment, and 4 patients (5%) underwent surgery at a mean of 3±2 years after their first treatment. Fifty-eight patients (77%) remained alive and free of redilation or surgery at follow-up. Larger annulus diameter and thinner membranes were independent factors associated with better long-term results.
Most patients (77%) with isolated thin discrete subaortic stenosis treated with transluminal balloon tearing of the membrane had sustained relief at subsequent follow-ups without restenosis, the need for surgery, progression to muscular obstructive disease, or an increase in the degree of aortic regurgitation.

ABSTRACT: The aim of our study is to assess changes in the epidemiologic features of patients with native valve infective endocarditis.
We analyzed a prospective series of 228 cases of native valve infective endocarditis in non-intravenous drug users attending our center between 1987 and 2009. We compared three subperiods: 1987-1994 (67 cases), 1995-2002 (74 cases) and 2003-2009 (87 cases).
The mean age of patients has progressively increased (38±22 years in the first subperiod vs 60±16 years in the third; P<.001), as has the proportion of cases without predisposing heart disease (25%, 46% and 67%; P<.001). Incidence of mitral valve prolapse remained stable (12%, 18% and 11%). Percentages of patients with predisposing heart disease and who were aware of their condition have fallen in recent years (45%, 27% and 21%; P<.001). A portal of entry for the infection could not be identified in 64%. Overall, Staphylococcus aureus is the most frequent causative organism (26%) whereas the percentage of cases caused by Streptococcus viridans remains unaltered (22%, 20% and 24%).
We found significant changes in the epidemiology of native valve infective endocarditis. The incidence of patients without predisposing heart disease has increased significantly and staphylococci are the most frequent causative organisms. Full English text available from: www.revespcardiol.org.

ABSTRACT: The prevalence of malnutrition among patients with heart failure and the role it might play in prognosis is not currently known. The aim of this study was to analyse the prevalence and risk of malnutrition as well as its possible influence on long-term mortality in patients with heart failure.
A prospective analysis was conducted on 208 patients discharged consecutively from our centre between January 2007 and March 2008 after being hospitalised with heart failure. Before discharge, a complete nutritional assessment was performed and diagnosis of malnutrition and risk of malnutrition was done with the Mini Nutritional Assessment. Its possible independent association with mortality was assessed by a Cox multivariate analysis.
The mean age of the patients was 73 ± 10 years, with 46% women; the most common aetiology of heart failure was ischaemia (41%). In addition, 13% were classified as malnourished, 59.5% at risk of malnutrition and 27.5% were well-nourished. At a median follow-up of 25 months, mortality in the three groups was 76%, 35.9% and 18.9%, respectively (log-rank, P<.001). In the Cox multivariate analysis, the malnutrition state was an independent predictor of mortality (hazard ratio 3.75, 95% confidence interval, 1.75-8.02, P=.001).
Malnutrition and the risk of malnutrition are highly prevalent in patients hospitalised for heart failure. Furthermore, we found that the state of malnutrition as defined by the Mini Nutritional Assessment survey is an independent predictor of mortality in these patients.

ABSTRACT: Despite the recognized benefit of intervention programs in patients with heart failure (HF), it is unknown whether different types of programs have similar efficacy. The aim of our study was to compare the effectiveness of three different types of intervention.
208 patients discharged with the diagnosis of HF were randomized. Fifty-two were assigned to each one of different groups of intervention (home visits, telephone follow-up, HF unit) and 52 patients to usual care (control group).
Median follow-up was 10.8±3.2 months. During the study, the primary end point (HF hospitalization or death) was reached in: 20 patients (38.5%) in control group, 19 (36.5%) in telephone follow-up (HR 1.11; IC95% [0.59-2.01], p=0.79), 24 (46.2%) in home visits (HR 1.27; IC95% [0.69-2.32], p=0.78) and 23 patients (44.2%) in HF unit (HR 1.33; IC95% [0.73-0.42], p=0.79). There was a trend to higher hospitalizations (shorter) with lower mortality in intervention groups (mortality: 23.1% intervention groups vs 33.3% in control group, HR 0.61 IC al 95% [0.35-1.01], p=0.08).
In our study, the application of three different intervention programs in patients with HF has a little non-significant prognosis benefit, with a slight increase in the number of shorts hospitalizations in HF unit.

ABSTRACT: The present report compared the incidence of 1-year clinical events in patients with bifurcation lesions that had been treated with a simple approach who were randomized to either a simultaneous final kissing balloon (KB) or an isolated side-branch (SB) balloon post-dilation. From February 2007 to December 2008, 293 patients with all types of Medina bifurcation lesions were enrolled in a prospective study. All patients underwent implantation of a sirolimus- or everolimus-eluting stent across the bifurcation and provisional SB stenting. Patients with no SB ostial compromise or those needing a second stent were excluded from the present study (n = 49). The eligible patients were randomly assigned to treatment with final KB inflation (n = 124, KB group) or isolated balloon after dilation (n = 120, non-KB group). No significant differences were found between the patients from the KB and non-KB groups in terms of age, risk factors, clinical status, or location of the bifurcation lesions. The angiographic data and immediate results were also similar in both groups. Four patients experienced a non-Q-wave acute myocardial infarction in the hospital: three (2%) from the KB group and one (1%) from the non-KB group. Two in-hospital deaths occurred in the non-KB group. Target lesion revascularization was required in 7 patients (3%): 5 from the KB group and 2 from the non-KB group. Late mortality occurred in 3 patients from the KB group and 2 patients from the non-KB group. The incidence of major events at 1 year (death, target lesion revascularization, or acute myocardial infarction) was similar in both groups: 11 (9%) from the KB group and 7 (6%) from the non-KB group (p = NS). In conclusion, no differences in the clinical outcome at 1 year of follow-up were observed between the patients with bifurcation lesions treated with a simple approach and either a simultaneous final KB or an isolated SB balloon post-dilation.

ABSTRACT: Our aim was to evaluate the effectiveness of oral anticoagulation (OAC) in patients aged ≥80 years with nonvalvular atrial fibrillation in daily clinical practice. From February 1, 2000 to June 30, 2009, we enrolled all patients aged ≥80 years with nonvalvular atrial fibrillation attended at 2 outpatient cardiology clinics of a tertiary care university hospital. The patients received antithrombotic treatment according to the recommendations from scientific societies and were prospectively followed, with major events (i.e., all-cause death, stroke, transient ischemic attack, peripheral embolism, severe bleeding) analyzed according to the treatment group (OAC vs no OAC). Of 269 patients included in the present study (87 men, mean age 83 ± 3 years), 164 received OAC (61%). After 2.8 ± 1.9 years of follow-up, the raw rates (per 100 patient-years) of embolic events (1.52% vs 8.30%, p <0.0001) and mortality (6.67% vs 10.94%, p = 0.04) were lower for patients receiving OAC, with a nonsignificant greater rate of severe bleeding (3.03% vs 1.25%, p = 0.14). The probability of survival free of major embolic or hemorrhagic events at the mean follow-up was greater for patients receiving OAC (82.27% vs 66.10%, p = 0.004). After adjustment for age, gender, coronary heart disease, and embolic risk, evaluated using the CHADS(2) score (congestive heart failure, 1 point; hypertension [blood pressure consistently >140/90 mm Hg or hypertension medication], 1 point; age ≥75 years, 1 point; diabetes mellitus, 1 point; previous stroke or transient ischemic attack, 2 points), only OAC was an independent predictor of embolic events (hazard ratio 0.17, 95% confidence interval 0.07 to 0.41, p <0.001). The CHADS(2) score (hazard ratio 1.32, 95% confidence interval 1.01 to 1.73, p = 0.04) and OAC (hazard ratio 0.52, 95% confidence interval 0.31 to 0.88, p = 0.01) were independent predictors of mortality. In conclusion, OAC according to the scientific societies' recommendations is effective and safe in daily clinical practice, even in patients aged ≥80 years.

ABSTRACT: The plaque distribution patterns in coronary bifurcation lesions are not well understood. It has been speculated that carina is free of plaque partly because of high wall shear stress providing an atheroprotective effect. To study plaque distribution with intravascular ultrasound (IVUS) in the coronary bifurcation and the prevalence of carina involvement.
IVUS study was performed on 195 coronary bifurcation lesions in the main vessel (MV) and on 91 in the side branch (SB). Plaque at the carina was considered when its thickness was > 0.3mm. Plaque burden was measured at different levels: proximal reference, distal, carina and at the point of minimal lumen area (MLA).
The prevalence of plaque at the carina was 32%. Its thickness was 0.8 (0.36) mm, less than that observed at the counter-carina [1.22 (0.54) mm; P<.01]. The prevalence was higher (52%) when the MLA point was distal to the carina. The plaque at the carina was associated with a lower incidence of damage at the SB ostium after stenting the MV (32% vs 54%; P<.04).
The carina is not immune to atherosclerosis, showing plaque at this level in one third of the bifurcations. The incidence of plaque is higher in those bifurcations with the MLA point distal to the carina and seems to be associated with a lower incidence of damage to the SB ostium.

ABSTRACT: The study investigated echocardiographic findings after 1 month in 22 patients who received a CoreValve prostheses to treat aortic valve stenosis. Particular attention was paid to the evaluation of valvular leaks and the left ventricular wall thickness. Echocardiograms were obtained prior to implantation, at discharge and 1 month later. The patients' mean age was 77 ± 4 years. At discharge, 16 patients (76%) had aortic regurgitation: 8 grade I and 8 grade II. At 1 month, only 13 (62%) presented with the condition: 10 grade I and 3 grade II, with 8 patients (38%) demonstrating a reduction of at least one grade (P < .005). The septal thickness decreased (from 14.2 ± 2 mm at baseline to 11 ± 2.4 mm at 1 month; P < .001), as did the posterior wall thickness (from 10.9 ± 2.4 mm at baseline to 8.3 ± 1.2 mm at 1 month; P < .001). In our patient series, the frequency and grade of residual aortic regurgitation after implantation of the CoreValve prosthesis decreased within 1 month, and favorable left ventricular remodeling was also observed.

ABSTRACT: We report our experience with the Venture wire-control catheter in 20 patients with bifurcation lesions in which it was impossible to access the side branch using conventional techniques. This device was always used as a last resort and was employed during different stages in the treatment of the bifurcation lesions (i.e. initially, after stenting of the main vessel or both). In 17 patients (85%), use of the Venture catheter resulted in the success of the procedure. Only one complication associated with a monorail catheter was recorded. It was resolved successfully. One patient died from heart failure 10 days after the procedure and two patients, in whom it was impossible to access the side branch, had non-Q-wave myocardial infarctions. In conclusion, the Venture catheter was effective and safe, and enabled the side branches of complex bifurcation lesions to be accessed.

ABSTRACT: Our aim was to investigate the prognostic value of the resting heart rate (RHR) in a broad unselected population of patients with stable coronary artery disease (sCAD).
Between February 1, 2000 and January 31, 2004, 1264 ambulatory patients with sCAD were recruited into the prospective study. Patients were followed up for major events (i.e. death, acute coronary syndrome, coronary revascularization, stroke, and hospitalization for heart failure). Associations between these events and the RHR (i.e. ≥ 70 beats per minute [bpm] versus < 70 bpm) were evaluated.
The patients' median age was 68 years (interquartile range [IQR] 60-74 years) and 926 (73%) were male. The RHR was ≥ 70 bpm in 645 patients (51%) and < 70 bpm in 619 (49%). After a median follow-up period of 25 months (IQR 12-39 months), with only seven patients lost to follow-up, the probability of an event was 17.48% in patients with an RHR ≥ 70 bpm and 17.67% in those with an RHR < 70 bpm (P =. 32) and total mortality was 2.32% and 2.5%, respectively (P = .56). After adjustment for age, sex, cardiovascular risk factors, blood pressure, baseline cardiac rhythm, ejection fraction and treatment at first visit, no significant association was found between the RHR and major events (hazard ratio [HR] = 1.04; 95% confidence interval [CI], 0.76-1.43; P = .79) or mortality (HR = 1.24; 95% CI, 0.55-2.81; P=.61).
The RHR was not an adverse prognostic factor in this group of unselected patients with sCAD. The prognostic value of the RHR in daily clinical practice could be low in this population.
