Patients with non-ST segment elevation acute coronary syndromes managed without coronary revascularization: A population needing treatment improvement.

NSTE-ACS patients are a heterogeneous population, with different clinical features and prognosis. A large proportion of them is medically managed, without any revascularization. In the EYSHOT and FAST-MI registries such patients were 40% and 35%, respectively. These patients are at higher risk of adverse cardiovascular events and have a worse prognosis compared with those receiving revascularization. Medically managed NSTE-ACS patients consist of different subgroups: those not undergoing coronary angiography, those without significant coronary artery disease, and those with coronary stenoses not referred to revascularization. Patients with NSTE-ACS for whom a conservative strategy without coronary angiogram is planned must be very carefully selected. In patients with comorbidities, frailty, or advanced age, a careful balance between benefits and risks is needed to choice the management strategy (perform or not coronary angiography and/or revascularization), as evidence-based medicine data are lacking in the setting of frailty and comorbidities. In this decisional process, it should be also taken into consideration the role of coronary anatomy in risk stratification and treatment guidance. NSTE-ACS patients managed without revascularization less frequently receive guideline-recommended pharmacological treatment. Dual antiplatelet therapy (DAPT) is recommended for 12months also in medically managed patients, after careful balancing of ischemic and bleeding risk. In these patients it is mandatory to optimize pharmacological treatment, including antiplatelet therapy, to improve outcome. In NSTE-ACS medically managed, the proportion of patients discharged with DAPT should be increased in comparison with current practice, and the use of ticagrelor in place of clopidogrel should be considered in selected patients.

[Patients with non-ST-elevation acute coronary syndrome managed without coronary revascularization: an undertreated population]. / I pazienti con sindrome coronarica acuta senza sopraslivellamento persistente del tratto ST non sottoposti a rivascolarizzazione coronarica: una popolazione sottotrattata.

Non-ST-elevation acute coronary syndromes (NSTE-ACS) represent one of the most common clinical presentations of ischemic heart disease. Patients with NSTE-ACS are a heterogeneous population, with different clinical features and prognosis. A significant proportion of this population is medically managed, without any revascularization. In the Italian EYESHOT and French FAST-MI registries, patients managed with a conservative strategy were 40% and 35%, respectively. NSTE-ACS patients not undergoing coronary revascularization are at higher risk of adverse cardiovascular events and have a worse prognosis, including short- and long-term mortality, compared with those receiving revascularization. Patients with NSTE-ACS medically managed consist of three different subgroups: those not undergoing coronary angiography, those receiving coronary angiography and without significant coronary artery disease, and those with significant coronary artery disease at angiography but not receiving revascularization. Patients presenting with NSTE-ACS for whom a conservative strategy without coronary angiography is planned should be selected very carefully and coronary angiography should not be denied because of the lack of on-site cath-lab facilities. In addition, advanced age alone, in the absence of severe comorbidities or frailty, should not be considered as a reason for denying coronary angiography and, in general, optimal treatment. Given that evidence-based data are lacking, a careful balance between benefits and risks is needed in the decision to perform or not coronary angiography and/or revascularization in patients with important comorbidities, or frailty, or advanced age. In this decisional process, it should be also taken into consideration the role of coronary anatomy in risk stratification and treatment guidance.NSTE-ACS patients managed without revascularization less frequently receive guideline-recommended pharmacological treatment. Dual antiplatelet therapy is recommended for 12 months also in medically managed patients, after careful balance of ischemic and bleeding risk. Indeed, in this group of patients it is mandatory to optimize pharmacological treatment, including antiplatelet therapy, in order to improve clinical outcome. In NSTE-ACS not undergoing revascularization, the proportion of patients discharged with dual antiplatelet therapy should be increased in comparison to current clinical practice, and the use of ticagrelor instead of clopidogrel should be considered in selected patients.

Trends of Prevalence of Uncontrolled Risk Factors for Cerebrocardiovascular Disease: Southern Italy from 1988/9 to 2008/9.

The aim of this study was to determine the trends of cardiovascular risk factor prevalence between 1988/9 and 2008/9 in the 25-74-year-old population in an area of Southern Italy. We compared three cross-sectional studies conducted in random population samples, in 1988/9, 1998/9, and 2008/9 in Salerno, Italy. The methodology of data collection (lipid profile, systolic and diastolic blood pressure, glycaemia, and smoking) and conducting tests which the population underwent during the three phases was standardized and comparable. Prevalence of diabetes, hypertension, hypercholesterolemia, and smoking was calculated and standardized for age. A total of 3491 subjects were included. From 1988/9 to 2008/9, in males, the prevalence of all four risk factors was reduced. In women, there was a clear reduction of hypertension, a similar prevalence of hypercholesterolemia, and an increase of smoking and diabetes. In the area of Salerno, our data confirm that the global prevalence of the major risk factors is decreasing in men, but their absolute values are still far from optimization. In women, diabetes and smoking showed a negative trend, therefore requiring targeted interventions. These data are now used as a base for executive targeted programs to improve prevention of cardiovascular disease in our community.

Clinical correlates of complicated grief among individuals with acute coronary syndromes.

OBJECTIVE: The study aimed at exploring bereavement and complicated grief (CG) symptoms among subjects without a history of coronary heart disease (CHD) at the time of a first acute coronary syndrome (ACS) and to evaluate the relationship of CG symptoms and ACS. METHOD: Overall, 149 subjects with ACS (namely, acute myocardial infarct with or without ST-segment elevation or unstable angina), with no previous history of CHD, admitted to three cardiac intensive care units were included and evaluated by the Structured Clinical Interview for Complicated Grief (SCI-CG), Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, and the 36-item Short-Form Health Survey (MOS-SF-36). RESULTS: Of the total sample of 149 subjects with ACS, 118 (79.2%) met criteria for DSM-5 persistent complex bereavement disorder. Among these, subjects who lost a partner, child, or sibling were older (P=0.008), less likely to be working (P=0.032), and more likely to be suffering from hypertension (P=0.021), returned higher scores on the SCI-CG (P=0.001) and developed the index ACS more frequently between 12 and 48 months after the death than those who lost a parent or another relative (P≤0.0001). The occurrence of ACS 12-48 months (P=0.019) after the loss was positively correlated with SCI-CG scores. An inverse relationship with SCI-CG scores was observed for patients who experienced ACS more than 48 months after the loss (P=0.005). The SCI-CG scores significantly predicted lower scores on the "general health" domain of MOS-SF-36 (P=0.030), as well as lower scores on "emotional well-being" domain (P=0.010). CONCLUSION: A great proportion of subjects with ACS report the loss of a loved one. Among these, the loss of a close relative and the severity of CG symptoms are associated with poorer health status. Our data corroborate previous data indicating a strong relationship between CG symptoms and severe cardiac problems.

Influence of depression and anxiety on circulating endothelial progenitor cells in patients with acute coronary syndromes.

OBJECTIVES: Circulating endothelial progenitor cells (EPCs) are related to endothelial function and progression of coronary artery disease. There is evidence of decreased numbers of circulating EPCs in patients with a current episode of major depression. We investigated the relationships between the level of circulating EPCs and depression and anxiety in patients with acute coronary syndrome (ACS). METHODS: Patients with ACS admitted to three Cardiology Intensive Care Units were evaluated by the SCID-I to determine the presence of lifetime and/or current mood and anxiety disorders according to DSM-IV criteria. The EPCs were defined as CD133(+) CD34(+) KDR(+) and evaluated by flow cytometry. All patients underwent standardized cardiological and psychopathological evaluations. Parametric and nonparametric statistical tests were performed where appropriate. RESULTS: Out of 111 ACS patients, 57 were found to have a DSM-IV lifetime or current mood or anxiety disorder at the time of the inclusion in the study. The ACS group with mood or anxiety disorders showed a significant decrease in circulating EPC number compared with ACS patients without affective disorders. In addition, EPC levels correlated negatively with severity of depression and anxiety at index ACS episode. CONCLUSIONS: The current study indicates that EPCs circulate in decreased numbers in ACS patients with depression or anxiety and, therefore, contribute to explore new perspectives in the pathophysiology of the association between cardiovascular disorders and affective disorders.

Post-procedural hemodiafiltration in acute coronary syndrome patients with associated renal and cardiac dysfunction undergoing urgent and emergency coronary angiography.

OBJECTIVES: We investigated the use of a 3-hr treatment with hemodiafiltration, initiated soon after emergency or urgent coronary angiography in acute coronary syndrome (ACS) patients with associated severe renal and cardiac dysfunction. BACKGROUND: Patients with ACS and severe combined renal and cardiac dysfunction have a particularly high mortality risk. In them, the ideal strategy to both optimize treatment of coronary disease and minimize renal injury risk is currently unknown. METHODS: This was an interventional study. ACS patients (STEMI and NSTEMI) with associated severe renal (eGFR ≤30 ml/min/1.73 m(2) ) and cardiac (LVEF ≤40%) dysfunction, admitted at La Spezia Hospital <24 hr from symptoms onset, underwent a prophylactic 3-hr hemodiafiltration treatment, which was started soon after urgent or emergency coronary procedure. Controls were patients matched for age, gender, Mehran's risk score, and kind of ACS, admitted at the Centro Cardiologico Monzino Milan. In-hospital and 1-year outcomes were evaluated. RESULTS: Sixty patients (30% STEMI), 30 hemodiafiltration-treated patients and 30 controls, with similar baseline characteristics, were included. In-hospital and cumulative 1-year mortality rates were significantly lower in hemodiafiltration-treated patients than in controls (3% vs. 23%; P = 0.05, and 10% vs. 53%; P < 0.001, respectively). Moreover, they had a lower incidence of severe AKI (10% vs. 40%; P = 0.015) and lower need for rescue renal replacement therapy during hospitalization (7% vs. 27%; P = 0.04). CONCLUSIONS: Our pilot study suggests that, in ACS patients with severe renal and cardiac insufficiency, treatment with an aggressive prophylactic hemodiafiltration session after urgent or emergency coronary angiography seems to be associated with a relevant improvement in survival.

[Choosing wisely: the Top 5 list of the Italian Association of Hospital Cardiologists (ANMCO)]. / "Fare di più non significa fare meglio". Le proposte dell'ANMCO.

In recent years, a progressive increase in the number of medical diagnostic and interventional procedures has been observed, namely in cardiology. A significant proportion of them appear inappropriate, i.e. potentially redundant, harmful, costly, and useless. Recently, the document Medical Professionalism in the New Millennium: A Physician Charter, the American Board of Internal Medicine (ABIM) Foundation Putting the Charter into Practice program, JAMA's Less Is More and BMJ's Too Much Medicine series, and the American College of Physicians' High-Value, Cost-Conscious Care initiatives, have all begun to provide direction for physicians to address pervasive overuse in health care. In 2010, the Brody's proposal to scientific societies to indicate the five medical procedures at high inappropriateness risk inspired the widely publicized ABIM Foundation's Choosing Wisely campaign. As part of Choosing Wisely, each participating specialty society has created lists of Things Physicians and Patients Should Question that provide specific, evidence-based recommendations physicians and patients should discuss to help make wise decisions about the most appropriate individual care. In Italy, Slow Medicine launched the analogue campaign Fare di più non significa fare meglio. The Italian Association of Hospital Cardiologists (ANMCO) endorsed the initiative by recognizing the need to optimize available resources, reduce costs and avoid unnecessary cardiovascular assessments, thereby enhancing the more efficient care delivery models. An ad hoc ANMCO Working Group prepared a list of five cardiac procedures that seem inappropriate for routine use in our country and, after an internal revision procedure, these are presented here.

Impact of depression on circulating endothelial progenitor cells in patients with acute coronary syndromes: a pilot study.

AIMS: Depression has been identified as a risk factor for an adverse prognosis and reduced survival in patients with acute coronary syndrome (ACS). The number of endothelial progenitor cells (EPCs) is an independent predictor of clinical outcomes in patients with ACS. The aim of this study was to evaluate the impact of depression on EPC levels in patients with ACS. METHODS: Out of 74 ACS patients [23 non-ST-segment elevation myocardial infarction (NSTEMI), 48 STEMI], 36 had a diagnosis of major depressive episode (MDE) according to the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) criteria at the time of the inclusion in the study. Control groups were as follows: 15 healthy individuals and 18 patients with current MDE without a history of cardiovascular diseases. EPCs were defined as CD34CD133KDR and evaluated by flow cytometry. All patients underwent standardized cardiological and psychopathological evaluations. Parametric and nonparametric statistical tests were performed wherever appropriate. RESULTS: ACS patients with MDE showed a significant decrease in circulating EPC number compared with ACS patients without MDE (P < 0.001). The ACS study population was then subdivided into STEMI and NSTEMI groups, and within each group patients with MDE again showed a significant decrease in circulating CD34CD133KDR EPCs compared with others (P <0.001). CONCLUSION: We showed that ACS patients with MDE have a reduced number of circulating CD34CD133KDR cells compared with ACS patients without MDE, suggesting that the presence of MDE reduces the response of bone marrow to acute ischemic events. Considering the reparative role of EPCs in ACS patients, we propose that patients with MDE might be protected less than patients without MDE.

Microalbuminuria predicts silent myocardial ischaemia in type 2 diabetes patients.

PURPOSE: Myocardial ischaemia is frequently silent in patients with type 2 diabetes. Although it has been proposed as a potential screening tool, the role of myocardial perfusion single photon emission computed tomography (MPS) has recently been questioned, due to the low prevalence of positive scans and the low rate of cardiac events. The aim of this study was to assess if pretest clinical variables can identify a subgroup of asymptomatic patients with type 2 diabetes at risk of silent myocardial ischaemia and a subsequent poor outcome METHODS: This prospective study included 77 patients (50 men, mean age 63 ± 9 years) with type 2 diabetes and no known coronary artery disease (CAD) or angina pectoris who underwent gated MPS to screen for CAD between March 2006 and October 2008. MPS images were interpreted using a semiquantitative visual 20-segment model to define summed stress, rest and difference scores. Ischaemia was defined as a sum difference score (SDS) ≥2. Patients were followed-up (median 4.1 years, range 0.8 - 6.1 years) and cardiac hard events (cardiac death or nonfatal myocardial infarction) were recorded. RESULTS: Silent ischaemia was detected in 25 of the 77 patients (32 %). Specifically, 10 patients (13 %) had mild ischaemia (SDS 2 to ≤4) and 15 patients (19 %) had severe ischaemia (SDS >4). In univariate binary logistic analysis, microalbuminuria was the only significant predictor of silent ischaemia on MPS (odds ratio 4.42, 95 % CI 1.27 - 15.40; P = 0.019). The overall accuracy of microalbuminuria for predicting silent ischaemia was 71.4 % and was 89.6 % for predicting severe ischaemia. Kaplan-Meier curves showed no significant group differences in 5-year cardiac event-free survival between patients with and those without microalbuminuria, or between patients with SDS ≥2 and those with SDS <2. In contrast, 5-year event-free survival was significantly lower in patients with SDS >4 than in patients with SDS ≤4: 55.6 % (95 % CI 39.0 - 72.2 %) vs. 94.5 % (95 % CI: 91.4 - 97.6 %), respectively (Breslow test, chi-square 20.9, P < 0.001). Median cardiac event-free survival was not observed in the whole group, while the 25th percentile of cardiac event-free survival was reached only in patients with SDS >4 (2.3 years). In univariate Cox regression analysis, SDS >4 predicted cardiac event-free survival (hazard ratio 12.87, 95 % CI 2.86 - 27.98; P = 0.001), while SDS ≥2 did not (hazard ratio 2.78, 95 % CI 0.62 - 12.46, P = 0.16). CONCLUSION: In this group of patients with type 2 diabetes, microalbuminuria was the only predictor of silent ischaemia on MPS. Assessment of microalbuminuria should be routinely considered among the first risk stratification steps for CAD in patients with type 2 diabetes, even though severe ischaemia on MPS is a major predictor of cardiac event-free survival.

The third component of the complement (C3) is a marker of the risk of atherogenesis.

AIM: The aim of this study was to assess the association between the third component of the complement (C3) and other risk factors of coronary heart disease. METHODS AND RESULTS: We evaluated 1200 individuals aged 25-74 years (600 men and 600 women). A strong relationship was shown between serum C3 and both body mass index (BMI, P<0.01) and fibrinogen (P<0.01). We found a significant, independent correlation with: platelet count (P<0.01), insulin level (P<0.01), triglycerides (P<0.01), low-density lipoprotein (LDL) cholesterol (P<0.01), and an inverse correlation with cigarette smoking (P<0.01). CONCLUSIONS: A high concentration of C3 is a marker of a profile at risk of atherogenesis.
