Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population

Prognostic Value and Therapeutic Perspectives of Coronary CT Angiography: A Literature Review

Coronary stenosis severity is both a powerful and a still debated predictor of prognosis in coronary artery disease. Coronary computed tomographic angiography (CCTA) has emerged as a noninvasive technique that enables anatomic visualization of coronary artery disease (CAD). CCTA with newer applications, plaque characterization and physiologic/functional evaluation, allows a comprehensive diagnostic and prognostic assessment of otherwise low-intermediate subjects for primary prevention. CCTA measures the overall plaque burden, differentiates plaque subtypes, and identifies high-risk plaque with good reproducibility. Research in this field may also advance towards an era of personalized risk prediction and individualized medical therapy. It has been demonstrated that statins may delay plaque progression and change some plaque features. The potential effects on plaque modifications induced by other medical therapies have also been investigated. Although it is not currently possible to recommend routinely serial scans to monitor the therapeutic efficacy of medical interventions, the plaque modulation, as a part of risk modification, appears a feasible strategy. In this review we summarize the current evidence regarding vulnerable plaque and effects of lipid lowering therapy on morphological features of CAD. We also discuss the potential ability of CCTA to characterize coronary atherosclerosis, stratify prognosis of asymptomatic subjects, and guide medical therapy

Rupture of Aneurysm of Valsalva Sinus and Aortopathy in Bicuspid Aortic Valve: A Case Report and Review of Literature

The bicuspid aortic valve (BAV) is one of the most common form of congenital heart defects. It is a complex entity, in which involvement of the thoracic aorta forms part of the disease spectrum. The ascending aorta is the most common site involved in this process. We report the extremely rare case of a patient with true BAV associated with a diffuse aortopathy, involving the aneurysm of the non coronary sinus, that suddenly rupted into the right atrium and required urgent cardiac surgery, and the aneurismal dilation of a (non aberrant) left subclavian artery, resembling a Kommerell’s diverticulum

Impact of preclinical carotid atherosclerosis on global cardiovascular risk stratification and events in a 10-year follow-up: comparison between the algorithms of the Framingham Heart Study, the European SCORE and the Italian 'Progetto Cuore'

BACKGROUND: The aim of the study was to compare three widely used algorithms for stratification of the global cardiovascular risk (GCVR): the Framingham Heart Study (FHS) score, the European systemic coronary risk estimation (SCORE) and the Italian 'Progetto Cuore' (heart project) score. It was also investigated how preclinical carotid atherosclerosis (pre-ATS) might influence the incidence and improve the risk prediction of cerebrovascular and cardiovascular events. METHODS: Subjects (n = 358) without previous history of cardiovascular disease (CVD) were recruited and the GCVR was calculated for each patient. An ultrasound evaluation of the carotid arteries was also performed. RESULTS: According to SCORE, the recruited population had globally a low risk of cardiovascular mortality and the risk equation estimated a GCVR of 2% in spite of the in spite of the observed rate of 0.8% (95% CI -0.001 to 0.02) of fatal events. The FHS and the 'Progetto Cuore' risk equations, regarding a 10-year risk of fatal and nonfatal events, predicted a low GCVR of 31 and 30%, an intermediate risk of 64 and 66%, and a high risk of 5 and 4% of the population respectively. They also estimated a general GCVR of 6.9 and 6.4% respectively versus an observed event rate 27.7 (95% CI 23.0 to 32.0). The discriminative power, calculated with the area under the receiving operator curve (AUROC), was 0.53 for SCORE, 0.54 for FHS and 0.55 for Progetto Cuore. Based on the ultrasound evaluation of carotid arteries, a first clinical event at 10-year follow-up was reported in 3% of subjects with normal ultrasound examination, 32% with intima-media thickening (IMT) and 62% with asymptomatic carotid plaque (ACP). CONCLUSION: The present study has evaluated for the first time the prediction of GCVR in an asymptomatic population, comparing three different risk scores. Carotid pre-ATS was related to the major cardiovascular risk factors (RFs) and was independently associated with a major incidence of cerebro- and cardiovascular events, therefore enhancing the predictive value of the three different risk scores

Non-responders to cardiac resynchronization therapy: Insights from multimodality imaging and electrocardiography. A brief review

Background Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes. Objectives In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter. However, we are so far from routinary use in clinical practice. Electrocardiography (with respect to left ventricle capture and QRS narrowing) may represent a simple and low cost approach for early prediction of potential non-responder, with immediate practical implications. Conclusion This brief review covers the current recommendations for CRT in HF patients with particular attention to the potential benefits of multimodality imaging and electrocardiography in improving response rate

Native Mitral Valve Endocarditis Caused by Neisseria elongata subsp. nitroreducens in a Patient with Marfan Syndrome: First Case in Italy and Review of the Literature

Neisseria elongata (NE) is an aerobic Gram-negative organism that constitutes part of the commensal human normal oropharyngeal flora. Although previously considered not to be pathogenic, it has been recognized as an occasional cause of significant infections in humans. We report here the first case in Italy of infective endocarditis of a native prolapsing mitral valve in a patient with Marfan syndrome, caused by NE subspecies nitroreducens which has been rarely isolated from clinical specimens. The culprit organism has been confirmed by mass spectrometry directly from the positive blood culture, as previously reported. The amplified gene has been deposited in GenBank under accession number KT591873. In spite of the reported aggressive nature of NE, clinical remission was promptly obtained, there being no requirement for surgery

Magnitude of QRS duration reduction after biventricular pacing identifies responders to cardiac resynchronization therapy

Background Several studies have investigated the association between native QRS duration (QRSd) or QRS narrowing and response to biventricular pacing. However, their results have been conflicting. The aim of our study was to determine the association between the relative change in QRS narrowing index (QI) and clinical outcome and prognosis in patients who undergo cardiac resynchronization therapy (CRT) implantation. Methods and results We included 311 patients in whom a CRT device was implanted in accordance with current guidelines for CRT. On implantation, the native QRS, the QRSd and the QI during CRT were measured. After 6 months, 220 (71%) patients showed a 10% reduction in LVESV. The median [25th–75th] QI was 14.3% [7.2–21.4] and was significantly related to reverse remodeling (r = + 0.22; 95%CI: 0.11–0.32, p = 0.0001). The cut-off value of QI that best predicted LV reverse remodeling after 6 months of CRT was 12.5% (sensitivity = 63.6%, specificity = 57.1%, area under the curve = 0.633, p = 0.0002). The time to the event death or cardiovascular hospitalization was significantly longer among patients with QI > 12.5% (log-rank test, p = 0.0155), with a hazard ratio (HR) of 0.3 [95%CI: 0.11–0.78]. In the multivariate regression model adjusted for baseline parameters, a 10% increment in QI (HR = 0.61[0.44–0.83], p = 0.002) remained significantly associated with CRT response. Conclusions Patients with a larger decrease in QRSd after CRT initiation showed greater echocardiographic reverse remodeling and better outcome from death or cardiovascular hospitalization. QI is an easy-to-measure variable that could be used to predict CRT response at the time of pacing site selection or pacing configuration programming
