[The heart failure management in Sicily: cognitive analysis of clinical features.] / La gestione dello scompenso cardiaco in Sicilia: analisi conoscitiva degli aspetti clinici e organizzativi.

INTRODUCTION: Heart failure (HF) is a main issue of modern healthcare system. Patient affected are continuously growing in number and age; therefore, an integrated management between different parts of healthcare system is crucial to optimize outcome and sustainability. So far, little is known about clinical pathways of HF patients in Sicily. METHODS: On initiative of the Regional HF Group of the Italian Association of Hospital Cardiologists (ANMCO), we decided to census all the Cardiology Unit of Sicily. A simple questionnaire elaborated by the group and exploring clinical and organizational matters of HF was sent to the Units. The answer arrived on a voluntary basis. RESULTS: 41/46 Units sent back the filled questionnaire. Five typologies of units were represented, based on complexity [1. Outpatient units; 2. Units without Intensive Care Unit (ICU); 3. Units with ICU; 4. Units with ICU and Cath Lab; 5. Units with ICU, Cath lab and Cardiac Surgery). A dedicated HF unit is present only in half centers, but it is formally recognized solely in 22% of Units. These Units have scarce dedicated staff and activity is predominantly based on personal initiative. Diagnostic and therapeutic tools are used appropriately in most of them, even though congestion is judged mainly through physical exam and echocardiography. Differently from the indications of the guidelines, post discharge titration of therapy lacks in almost 30% of centers. DISCUSSION AND CONCLUSIONS: In Sicily, HF is managed on a plan mainly based on personal initiative. The quality is sufficiently good but a more appropriate and structured organization in particular of the follow-up seems a necessary and improvable requirement in view of quality measurers and economic sustainability of health care.

Chronic Stanford type A aortic dissection.

: Chronic evolution of type A acute aortic dissection is not frequently observed in untreated patients because of the high mortality rate. Chronic aortic dissection is usually asymptomatic and may be incidentally discovered following an asymptomatic acute dissection. The life expectancy in these patients is prolonged by graft replacement therapy when the aortic diameter exceeds 55 mm. We report a case of a paucisymptomatic 78-year-old woman in whom chest X-ray revealed a right calcified mass.

Extracorporeal membrane oxygenation for graft failure after heart transplantation: a multidisciplinary approach to maximize weaning rate.

OBJECTIVES: Primary graft failure (PGF) after heart transplantation is a detrimental complication, and carries high morbidity and mortality. The aim of this study was to analyze the results of our multidisciplinary approach in supporting patients affected with PGF after heart transplantation. METHODS: Out of 114 consecutive patients receiving orthotopic heart transplantation between January 2006 and July 2013, 18 (15.7%) developed PGF requiring veno-arterial extracorporeal membrane oxygenator (VA-ECMO) support. Fourteen patients were male and the mean age was 49±11 years. General principles in treating the patients were based on a low dose of adrenaline (0.05 mic/kg per min) infusion; femoral intra-aortic balloon pump (13 of the 18 patients); low dose of vasoconstrictors; careful fluid balance; daily echocardiographic transesophageal monitoring. RESULTS: Mean graft recipient pulmonary vascular resistance was 3.6±3.2 WU. Five patients had absolute contraindication to IABP placement. The mean left ventricle ejection fraction pre-VA-ECMO was 18.4%±10.2%. The mean VA-ECMO and IABP support times were 6.7±3.2 and 9.2±7.6 days, respectively. Mean VA-ECMO flow was 4164±679 l/min. The mean left ventricle ejection fraction increased to 43.4%±17.7% at the end of support. Weaning and discharge rates in patients treated with VA-ECMO+IABP were 84% and 53%, respectively. Causes of death were primarily end-stage organ failure. CONCLUSIONS: A multidisciplinary evaluation of ECMO patients done by intensivists, cardiologists, and surgeons may influence weaning and survival rate. Our approach seems to be a safe and reproducible strategy for avoiding left ventricle distension and fluid overload, and for detecting complications that negatively affect outcomes.

Vitamin K antagonists in patients with nonvalvular atrial fibrillation: appropriateness and quality of treatment in an Italian cohort.

BACKGROUND: Vitamin K antagonists (VKA) are highly recommended in patients with atrial fibrillation for their efficacy in preventing stroke. However, there is a lack of data on oral anticoagulation (OAC) with VKA overall treatment (i.e. from writing the prescription to time spent in therapeutic range) in patients discharged from hospital with a diagnosis of atrial fibrillation. OBJECTIVE: The aim of this study was to assess the adherence to stroke prevention guidelines in a cohort of patients discharged with atrial fibrillation from the two hospitals of the Agency for Health Services no. 3 'Upper Friuli'. METHODS: All patients discharged from the hospitals with a diagnosis of nonvalvular atrial fibrillation during the year 2009 were enrolled in this study. Record linkage for the previous 5 years and pharmaceutical data were used to assess comorbid conditions (ICD9-CM) and to calculate congestive heart failure, hypertension, age at least 75 years, diabetes and stroke (CHADS2) scores. Prescription orders were obtained from discharge letters. Patients' adherence to VKA prescription was assessed through pharmacy records, and prothrombin/international normalized ratios (INR) for a period of 180 days after discharge from the whole 'Upper Friuli' laboratories. A patient was considered to have purchased VKA if at least one drug purchase was found in the pharmacy records. Time in therapeutic range (TTR) was calculated in patients who had at least two INR measurements. RESULTS: In 2009, 509 patients (mean age 80 ±â€Š8 years) were discharged with atrial fibrillation from 'Upper Friuli' hospitals (90% from internal medicine); of these, 284 patients (55.8%) had a CHADS2 score greater than 1 and no contraindications to VKA therapy at discharge. Within this subgroup, 112 patients (39.4%) received VKA prescription at discharge; of these, 84 (29.6%) purchased VKA and 58 patients had a TTR of at least 65% (20.4%). CONCLUSION: VKA prescription for atrial fibrillation patients is low and not explained by present or past comorbid condition. A second failure is represented by patients' low compliance. Overall, adherence to VKA guidelines in atrial fibrillation is scarce.

Impact of diabetes mellitus on long-term follow-up of percutaneous coronary intervention based on clinical presentation of coronary artery disease.

AIMS: In the drug-eluting stent (DES) era, diabetes mellitus is still associated with poor clinical and angiographic outcome after PCI. Whether this phenomenon is exacerbated in the setting of acute coronary syndromes (ACS) is unclear. We investigated the long-term interaction of diabetes mellitus and clinical presentation in patients treated with percutaneous coronary intervention (PCI). METHODS: Consecutive patients undergoing PCI and DES implantation were retrospectively analyzed. The 3-year composite of death, non-fatal myocardial infarction (MI) or target vessel revascularization (TVR) was assessed. RESULTS: Four subgroups of patients were identified: diabetes mellitus and ACS (n = 302); diabetes mellitus and no-ACS (n = 191); no-diabetes mellitus and ACS (n = 573); no-diabetes mellitus and no-ACS (n = 396). Compared to non-diabetes mellitus, diabetes mellitus patients experienced higher 3-year rates of death, non-fatal MI or TVR (32.3 vs. 21.9%, P < 0.001). Diabetes mellitus was significantly associated with the composite of death, non-fatal MI or TVR in the no-ACS group [adjusted hazard ratio (AHR) 1.307, 95% confidence interval (CI) 1.090-1.566, P = 0.004] and, albeit to a lesser extent, in the ACS group (AHR 1.177, 95% CI 1.006-1.377, P = 0.041). No statistically significant interaction was observed between diabetes mellitus and clinical presentation (P for interaction = 0.802). CONCLUSIONS: No significant interaction between diabetes mellitus and clinical presentation was noted in this study. The high rates of cardiac events observed in diabetes mellitus patients despite recent advances in interventional techniques outline the need for a multidisciplinary approach in the management of diabetes mellitus patients, including optimization of glycemic control, aggressive medical therapy and more complete coronary revascularization.

Sirolimus versus paclitaxel-eluting stents in small coronary vessels: long-term outcomes from a single-center registry.

OBJECTIVE: Several studies showed that small vessel diameter is a determinant of increased risk of adverse events after stenting. The efficacy of different drug-eluting stent types implanted in small vessels has still not been established. The aim of the present observational study was to compare long-term clinical outcomes after sirolimus-eluting stent (SES) or paclitaxel-eluting stent (PES) implantation in lesions located in small coronary vessels. METHODS: For the purpose of this analysis patients undergoing SES or PES implantation in vessels with diameter 2.5 mm or less, from May 2002 to December 2006, were included. Long-term rates of major adverse cardiac events were evaluated and compared between the two groups. Independent predictors of major adverse cardiac events were also investigated. RESULTS: A total of 336 patients were included, 225 were treated only with SES and 111 only with PES. During a mean follow-up of 23.3 +/- 12.1 months the major adverse cardiac events rates were 12.8 versus 13.6%, P = 0.98 in SES versus PES groups, respectively. The rates of target lesion revascularization (8.0 versus 6.3%, P = 0.75), mortality (3.5 versus 4.5%, P = 0.88) and myocardial infarction (2.6 versus 4.5%, P = 0.41) were similar between SES and PES, respectively. The overall thrombosis rate was also not significantly different in SES and PES groups (1.3% SES versus 4.5% PES, P = 0.12). CONCLUSION: In this study SES and PES provided similar long-term results after treatment of lesions in small vessels. Nevertheless, larger randomized studies are needed to confirm these findings.

EuroSCORE refines the predictive ability of SYNTAX score in patients undergoing left main percutaneous coronary intervention.

BACKGROUND: Whether SYNTAX score should be used as a stand-alone tool or whether its performance may be improved by the parallel use of clinical scores focusing on comorbidities, such as EuroSCORE, is a matter of debate. METHODS: A combined risk model including both clinical and angiographic information was developed, and its performance tested on a contemporary population of 255 patients with left main disease undergoing percutaneous coronary intervention (PCI). A global risk classification (GRC) system was created by combination of SYNTAX score and EuroSCORE strata, and new classes of risk were defined. RESULTS: When EuroSCORE was fitted into the SYNTAX score model, c-statistic increased from 0.681 to 0.732 for the prediction of cardiac mortality. The likelihood ratio test for the significance of adding the EuroSCORE term to the model was chi(2) = 4.109 (P = .043) with a net reclassification improvement of 26% (P = .002). GRC showed the best prediction and discriminative ability in terms of two-year cardiac mortality (HR 3.40, 95% CI 1.79-6.43, P < .001; c-statistic 0.756) as compared with SYNTAX score (HR 2.87, 95% CI 1.35-6.10, P = .006; c-statistic 0.747) and EuroSCORE (HR 3.04, 95% CI 1.41-6.57, P = .005; c-statistic 0.708) alone. CONCLUSIONS: We found a significant improvement in the prediction of cardiac mortality with the inclusion of EuroSCORE in a SYNTAX score-based model. The degree of reclassification between treatment threshold categories indicates that clinical and angiographic information are both important for assessing individual risk of patients undergoing left main PCI.

Sirolimus- vs. paclitaxel-eluting stents in patients undergoing off-label percutaneous coronary intervention.

Studies of percutaneous coronary intervention (PCI) with drug-eluting stents in high-risk scenarios are often limited by short follow up and use definitions of "off-label" PCI which do not entirely mirror insert packages recommendations. We analyzed the incidence of cardiovascular events in 1050 consecutive patients undergoing off-label PCI with sirolimus- (n=581) or paclitaxel- (n=469) eluting stents. At 3 years, there were no differences between groups in terms of major cardiovascular events (adjusted hazard ratio 0.991; 95% CI, 0.758 to 1.295; p=0.945), despite slightly higher rates of myocardial infarction and late stent thrombosis seen among patients who received paclitaxel-eluting stents.

Long-term outcomes comparison of different types of DES in elderly patients from a real-world experience.

OBJECTIVE: We sought to evaluate the impact on long-term clinical outcomes of different types of drug-eluting stents (DES) in elderly patients. BACKGROUND: Elderly patients constitute a fast-growing portion of cardiovascular patients, however, they are not adequately represented in clinical trials. Moreover, few data comparing different type of DES in elderly patients are available. METHODS: From a total of 2,330 consecutive patients treated at our institution with DES, we selected 207 elderly patients (> or = 75 years of age) who underwent, from May 2002 to December 2006, sirolimus-eluting stent (SES group, 116 patients [pts], 56%) or paclitaxel-eluting stent (PES group, 91 pts, 43.9%) implantation. We evaluated the 24-month incidence of major adverse cardiac events (MACE). RESULTS: Higher rates of hypertension (78.4% vs. 90.1%; p = 0.01), diabetes (37.9 vs. 45.1; p = 0.01) and previous coronary artery bypass grafts (10.3% vs. 19.4%; p = 0.04) in the PES group were observed, whereas in the SES group, there were more smokers (26.6% vs. 12.1%; p = 0.007) and a higher incidence of previous myocardial infarction (MI) (50% vs. 35.2%; p = 0.02). Procedural success and in-hospital MACE were similar in both groups. At follow up, there was a higher incidence of MACE (22.4% vs. 10.9%; p = 0.04) and target lesion revascularization (7.1% vs. 3.0%; p = 0.02) in the SES group compared to the PES group. The incidence of cardiac death and MI were comparable between the two groups, as well as the rate of stent thrombosis. After adjustment for clinical and angiographic characteristics, no significant differences in outcomes were observed between SES and PES. CONCLUSIONS: In this real-word experience, no significant differences were found in the safety and efficacy profiles between SES and PES use in elderly patients.

A novel approach to define risk of stent thrombosis after percutaneous coronary intervention with drug-eluting stents: the DERIVATION score.

Recent studies of drug-eluting stents (DES) use in routine clinical practice have led to concern regarding their long-term safety and to questions about the adequacy of current antiplatelet therapy guidelines. This study sought to derivate a risk score for predicting stent thrombosis after drug-eluting stenting. The large single center DES Real-world Incremental Value in the erA of percutaneous revascularizaTION (DERIVATION) database, collecting data about 1,377 patients of any age undergoing PCI with DES as treatment for symptomatic coronary artery disease, was use for this purpose. Logistic regression and bootstrap procedure were used to select correlates of stent thrombosis that were subsequently weighted and integrated into an integer scoring system. Five variables selected from the initial multivariate model were weighted proportionally to their respective odds ratio for stent thrombosis [baseline left ventricular ejection fraction <50% (4 points), angioplasty in the setting of acute coronary syndromes (3 points), bifurcation lesion (2 points), left anterior descending as target vessel (2 points), multiple stenting (2 points)]. Three strata of risk were defined (low risk, 0-2; intermediate risk, 3-6; high risk >or=7) with good prognostic accuracy for early, late and very late thrombosis (c statistic = 0.75, 0.65 and 0.73, respectively) in the derivation set. In conclusion, the DERIVATION score may be used as a simple clinical tool for the identification of a sizable cohort in whom close monitoring and aggressive therapy may be beneficial.
