Percutaneous Coronary Intervention for Chronic Total Occlusion

Treatment of coronary chronic total occlusions represents one of the major challenges in the field of interventional cardiology. This is due to the complexity of these procedures and to the relatively higher risk of complications. In recent years, the development of innovative techniques and the evolution of materials have produced significant progress in this field. Better procedural outcomes have been achieved, with fewer complications. This article highlights the most recent scientific evidence and techniques, with the intention to guide interventional cardiologists in optimal patient selection and procedure choice

Complexity in hospital internal medicine departments: What are we talking about?

Internal medicine (IM) patients are mostly elderly, with multiple complex co-morbidities, usually chronic. The complexity of these patients involves the intricate entanglement of two or more systems (e.g. body and disease, family-socio-economic and environmental status, coordination of care and therapies) and this requires comprehensive, multi-dimensional assessment (MDA). Despite attempts to improve management of chronic conditions, and the availability of several MDA tools, defining the complex patient is still problematic. The complex profile of our patients can only be described through the best assessment tools designed to identify their characteristics. In order to do this, the Federation of Associations of Hospital Doctors on Internal Medicine FADOI has created its own vision of IM. This involves understanding the different needs of the patient, and analyzing diseases clusters and the possible relationships between them. By exploring the real complexity of our patients and selecting their real needs, we can exercise holistic, anthropological and appropriate choices for their treatment and care. A simpler assessment approach must be adopted for our complex patients, and alternative tools should be used to improve clinical evaluation and prognostic stratification in a hierarchical selection of priorities. Further investigation of complex patients admitted to IM wards is needed

Intracoronary physiology-guided percutaneous coronary intervention in patients with diabetes

Objective: The risk of vessel-oriented cardiac adverse events (VOCE) in patients with diabetes mellitus (DM) undergoing intracoronary physiology-guided coronary revascularization is poorly defined. The purpose of this work is to evaluate the risk of VOCE in patients with and without DM in whom percutaneous coronary intervention (PCI) was performed or deferred based on pressure-wire functional assessment. Methods: This is a retrospective analysis of a multicenter registry of patients evaluated with fractional flow reserve (FFR) and/or non-hyperaemic pressure ratio (NHPR). Primary endpoint was a composite of VOCE including cardiac death, vessel-related myocardial infarction (MI), and ischemia-driven target vessel revascularization (TVR). Results: A large cohort of 2828 patients with 3353 coronary lesions was analysed to assess the risk of VOCE at long-term follow-up (23 [14-36] months). Non-insulin-dependent-DM (NIDDM) was not associated with the primary endpoint in the overall cohort (adjusted Hazard Ratio [aHR] 1.18, 95% CI 0.87-1.59, P = 0.276) or in patients with coronary lesions treated with PCI (aHR = 1.30, 95% CI 0.78-2.16, P = 0.314). Conversely, insulin-dependent diabetes mellitus (IDDM) demonstrated an increased risk of VOCE in the overall cohort (aHR 1.76, 95% CI 1.07-2.91, P = 0.027), but not in coronary lesions undergoing PCI (aHR 1.26, 95% CI 0.50-3.16, P = 0.621). Importantly, in coronary lesions deferred after functional assessment IDDM (aHR 2.77, 95% CI 1.11-6.93, P = 0.029) but not NIDDM (aHR = 0.94, 95% CI 0.61-1.44, P = 0.776) was significantly associated with the risk of VOCE. IDDM caused a significant effect modification of FFR-based risk stratification (P for interaction < 0.001). Conclusion: Overall, DM was not associated with an increased risk of VOCE in patients undergoing physiology-guided coronary revascularization. However, IDDM represents a phenotype at high risk of VOCE

Clinical characteristics of very old patients hospitalized in internal medicine wards for heart failure: a sub-analysis of the FADOI-CONFINE Study Group

The incidence and prevalence of chronic heart failure are increasing worldwide, as is the number of very old patients (>85 years) affected by this disease. The aim of this sub-analysis of the multicenter, observational CONFINE study was to detect clinical and therapeutic peculiarities in patients with chronic heart failure aged >85 years. We recruited patients admitted with a diagnosis of chronic heart failure and present in the hospital in five index days, in 91 Units of Internal Medicine. The patients' clinical characteristics, functional and cognitive status, and the management of the heart failure were analyzed. A total of 1444 subjects were evaluated, of whom 329 (23.1%) were over 85 years old. Signs and symptoms of chronic heart failure were more common in very old patients, as were severe renal insufficiency, anemia, disability and cognitive impairment. The present survey found important age-related differences (concomitant diseases, cognitive status) among patients with chronic heart failure, as well as different therapeutic strategies and clinical outcome for patients over 85 years old. Since these patients are usually excluded from clinical trials and their management remains empirical, specific studies focused on the treatment of very old patients with chronic heart failure are needed

Complexity of patients with chronic obstructive pulmonary disease hospitalized in internal medicine: a survey by FADOI

Chronic obstructive pulmonary disease (COPD) is one of the most frequent pathologies among patients hospitalized in Internal Medicine (IM) Departments. COPD is frequently associated with concomitant diseases, which represent major causes of death, and affect disease management. Objectives of our study are to assess the prevalence of COPD patients in IM, to evaluate their comorbidity status, and to describe their complexity, by means of the validated multidimensional prognostic index (MPI) score. COMPLEXICO is an observational, prospective, multicenter study, enrolling consecutive patients hospitalized for any cause in IM, with diagnosis of COPD documented by spirometry. A total of 1002 patients in 43 IM Units in Italy were enrolled. The prevalence of COPD in IM was found to be 18.1%, and 72.8% of patients had at least three chronic diseases other than COPD. The mean MPI was 0.43±0.15, and according to a stratification algorithm 31.8% of patients were classified as having low-risk, 58.9% moderate-risk and 9.3% severe-risk of adverse outcome. More than two-thirds of COPD patients in our study present moderate to severe risk of poor outcome according to the MPI stratification

Dental Health and Mortality in People With End-Stage Kidney Disease Treated With Hemodialysis: A Multinational Cohort Study

Background Dental disease is more extensive in adults with chronic kidney disease, but whether dental health and behaviors are associated with survival in the setting of hemodialysis is unknown. Study Design Prospective multinational cohort. Setting & Participants 4,205 adults treated with long-term hemodialysis, 2010 to 2012 (Oral Diseases in Hemodialysis [ORAL-D] Study). Predictors Dental health as assessed by a standardized dental examination using World Health Organization guidelines and personal oral care, including edentulousness; decayed, missing, and filled teeth index; teeth brushing and flossing; and dental health consultation. Outcomes All-cause and cardiovascular mortality at 12 months after dental assessment. Measurements Multivariable-adjusted Cox proportional hazards regression models fitted with shared frailty to account for clustering of mortality risk within countries. Results During a mean follow-up of 22.1 months, 942 deaths occurred, including 477 cardiovascular deaths. Edentulousness (adjusted HR, 1.29; 95% CI, 1.10-1.51) and decayed, missing, or filled teeth score ≥ 14 (adjusted HR, 1.70; 95% CI, 1.33-2.17) were associated with early all-cause mortality, while dental flossing, using mouthwash, brushing teeth daily, spending at least 2 minutes on oral hygiene daily, changing a toothbrush at least every 3 months, and visiting a dentist within the past 6 months (adjusted HRs of 0.52 [95% CI, 0.32-0.85], 0.79 [95% CI, 0.64-0.97], 0.76 [95% CI, 0.58-0.99], 0.84 [95% CI, 0.71-0.99], 0.79 [95% CI, 0.65-0.95], and 0.79 [95% CI, 0.65-0.96], respectively) were associated with better survival. Results for cardiovascular mortality were similar. Limitations Convenience sample of clinics. Conclusions In adults treated with hemodialysis, poorer dental health was associated with early death, whereas preventive dental health practices were associated with longer survival

Parametric analysis of flat top beam patterns generated by linear periodic arrays

The synthesis of linear periodic arrays generating flat top beam patterns is a canonical problem which has been investigated adopting different algorithms. In this contribution a parametric investigation is proposed in order to appreciate how the pattern evolves as a function of different design parameters like the array dimension, the beam flatness, the beam roll-off and the sidelobe levels. The numerical results proposed are based on linear programming synthesis techniques which guarantee optimality of the solutions for the given set of parameters
