[Identification and treatment of high-risk coronary atheromatous plaques: towards a shared strategy between the clinical and interventional cardiologist]. / Identificazione e trattamento della placca ateromasica coronarica ad alto rischio: verso una strategia condivisa tra il cardiologo clinico e l'interventista.

Modern coronary diagnostic methods, including cardiac computed tomography and intracoronary imaging, allow the identification of vulnerable coronary plaques with a high probability of complicating and causing acute coronary syndrome. The treatment limited to the plaques responsible for ischemic events could not be enough to prevent major cardiovascular events because most flow-limiting plaques are quiescent or slowly evolving. In several cases the plaques responsible for acute event determine a moderate reduction of the vessel lumen but have well-defined characteristics of vulnerability. The purpose of this review is (i) to describe the characteristics of these plaques based on both the pathological anatomy and computed tomography and intracoronary imaging findings and the associated clinical risk of developing future coronary events; (ii) to evaluate available trials on early treatment of vulnerable plaques by percutaneous revascularization; and (iii) to propose a decision-making algorithm in primary prevention integrating the search for myocardial ischemia and vulnerable plaques.

COMPASS criteria applied to a contemporary cohort of unselected patients with stable coronary artery diseases: insights from the START registry.

AIMS: Recently, the cardiovascular outcomes for people using anticoagulation strategies (COMPASS) trial demonstrated that dual therapy reduced cardiovascular outcomes compared with aspirin alone in patients with stable atherosclerotic disease. METHODS AND RESULTS: We sought to assess the proportion of patients eligible for the COMPASS trial and to compare the epidemiology and outcome of these patients with those without COMPASS inclusion or with any exclusion criteria in a contemporary, nationwide cohort of patients with stable coronary artery disease. Among the 4068 patients with detailed information allowing evaluation of eligibility, 1416 (34.8%) did not fulfil the inclusion criteria (COMPASS-Not-Included), 841 (20.7%) had exclusion criteria (COMPASS-Excluded), and the remaining 1811 (44.5%) were classified as COMPASS-Like. At 1 year, the incidence of major adverse cardiovascular event (MACE), a composite of cardiovascular death, myocardial infarction, and stroke, was 0.9% in the COMPASS-Not-Included and 2.0% in the COMPASS-Like (P = 0.01), and 5.0% in the COMPASS-Excluded group (P < 0.0001 for all comparisons). Among the COMPASS-Like population, patients with multiple COMPASS enrichment criteria presented a significant increase in the risk of MACE (from 1.0% to 3.3% in those with 1 and ≥3 criteria, respectively; P = 0.012), and a modest absolute increase in major bleeding risk (from 0.2% to 0.4%, respectively; P = 0.46). CONCLUSION: In a contemporary real-world cohort registry of stable coronary artery disease, most patients resulted as eligible for the COMPASS. These patients presented a considerable annual risk of MACE that consistently increases in the presence of multiple risk factors.

External applicability of the ISCHEMIA trial: an analysis of a prospective, nationwide registry of patients with stable coronary artery disease.

AIMS: We sought to assess the proportion of patients eligible for the ISCHEMIA trial and to compare the characteristics and outcomes of these patients with those without ISCHEMIA inclusion or with ISCHEMIA exclusion criteria in a contemporary, nationwide cohort of patients with stable coronary artery disease (CAD). METHODS AND RESULTS: Among the 5,070 consecutive patients enrolled in the START registry, 4,295 (84.7%) did not fulfil the inclusion criteria (ISCHEMIA-Not Included or ISCHEMIA-Unclassifiable), 582 (11.5%) had exclusion criteria (ISCHEMIA-Excluded), and the remaining 193 (3.8%) were classified as ISCHEMIA-Like. At one year, the incidence of the primary outcome, a composite of death from cardiovascular (CV) causes, myocardial infarction (MI), or hospitalisation for unstable angina and heart failure, was 0.5% in the ISCHEMIA-Like versus 3.3% in other patients (p=0.03). The composite secondary outcome of CV mortality and MI occurred in 0.5% of the ISCHEMIA-Like patients and in 1.4% of the remaining patients (p=0.1). CONCLUSIONS: In a contemporary real-world cohort of stable CAD patients, only 4% resulted in being eligible for the ISCHEMIA trial. These patients presented an extremely low annual risk of adverse events, especially when compared with other groups of stable CAD patients.

Lights and shadows of long-term dual antiplatelet therapy in "real life" clinical scenarios.

Dual antiplatelet therapy (DAPT) is a cornerstone of treatment for patients with acute coronary syndromes (ACS). Mounting evidences have opened the debate about the optimal DAPT duration. Considering the ACS-pathophysiology, the most recent guidelines recommend DAPT in all ACS patients for at least 12 months unless there are contraindications such as excessive risk of bleeding. Thus, it can be considered acceptable earlier discontinuation if the risk of morbidity from bleeding outweighs the anticipated benefit. On the other hand, several studies have clearly indicated that a significant burden of platelet related-events, such as stroke and new ACS might occur after this period, suggesting that potential benefits might derive by prolonging DAPT beyond 12 months (Long DAPT). Indeed, although current guidelines give some indications about patients eligible for Long DAPT, they do not embrace several real-life clinical scenarios. Thus, in such scenarios, how to decide whether a patient is eligible for Long DAPT or not might be still challenging for clinicians. This position paper presents and discusses various "real-life" clinical scenarios in ACS patients, in order to propose several possible recommendations to overcome guidelines potential limitations.

Current management and treatment of patients with stable coronary artery diseases presenting to cardiologists in different clinical contexts: A prospective, observational, nationwide study.

Background Stable coronary artery disease (CAD) is a leading cause of mortality worldwide. Few studies document the complete sequence of investigation of the overall stable CAD population during outpatient visits or hospitalisation. Aim To obtain accurate and up-to-date information on current management of patients with stable CAD. Methods START (STable coronary Artery diseases RegisTry) was a prospective, observational, nationwide study aimed at evaluating the presentation, management, treatment and quality of life of stable CAD patients presenting to cardiologists during outpatient visits or discharged from cardiology wards. Results Over a 3-month period, 5070 consecutive patients were enrolled in 183 participating centres: 72% managed by a cardiologist during outpatient or day hospital visits and 28% discharged from cardiology wards. The vast majority of patients (87%) received a coronary angiography (86% of patients managed during outpatient visits and 90% during hospitalisation; p < 0.0001). Outpatients more frequently received optimal medical therapy (OMT; i.e. aspirin or thienopyridine, ß-blockers and statins) compared to hospitalised patients (70.2% vs 67.1%; p = 0.03). A personalised diet was prescribed in 58% (60.5% in outpatients and 52.9% in those admitted to hospitals; p < 0.0001), physical activity programmes were suggested in 65% (69.4% and 54.3%; p < 0.0001) and smoking cessation was recommended in 71% of currently smoking patients (73.2% and 65.2%; p = 0.02). Conclusions In this large, contemporary registry, patients with stable CAD discharged from cardiology wards more commonly underwent diagnostic imaging procedures and less frequently received OMT or lifestyle modification programmes compared to patients manged by cardiologists during outpatient visits.

Consensus Document of the Italian Association of Hospital Cardiologists (ANMCO), Italian Society of Cardiology (SIC), Italian Association of Interventional Cardiology (SICI-GISE) and Italian Society of Cardiac Surgery (SICCH): clinical approach to pharmacologic pre-treatment for patients undergoing myocardial revascularization procedures.

The wide availability of effective drugs in reducing cardiovascular events together with the use of myocardial revascularization has greatly improved the prognosis of patients with coronary artery disease. The combination of antithrombotic drugs to be administered before the knowledge of the coronary anatomy and before the consequent therapeutic strategies, can allow to anticipate optimal treatment, but can also expose the patients at risk of bleeding that, especially in acute coronary syndromes, can significantly weigh on their prognosis, even more than the expected theoretical benefit. In non ST-elevation acute coronary syndromes patients in particular, we propose a 'selective pre-treatment' with P2Y12 inhibitors, based on the ischaemic risk, on the bleeding risk and on the time scheduled for the execution of coronary angiography. Much of the problems concerning this issue would be resolved by an early access to coronary angiography, particularly for patients at higher ischaemic and bleeding risk.

ANMCO Position Paper: the use of non-vitamin K dependent new oral anticoagulant(s) in pulmonary embolism therapy and prevention.

The new oral anticoagulants (NOACs) have radically changed the approach to the treatment and prevention of thromboembolic pulmonary embolism. The authors of this position paper face, in succession, issues concerning NOACs, including (i) their mechanism of action, pharmacodynamics, and pharmacokinetics; (ii) the use in the acute phase with the 'double drug single dose' approach or with 'single drug double dose'; (iii) the use in the extended phase with demonstrated efficacy and with low incidence of bleeding events; (iv) the encouraging use of NOACs in particular subgroups of patients such as those with cancer, the ones under- or overweight, with renal insufficiency (creatinine clearance > 30 mL/min), the elderly (>75 years); (v) they propose a possible laboratory clinical pathway for follow-up; and (vi) carry out an examination on the main drug interactions, their potential bleeding risk, and the way to deal with some bleeding complications. The authors conclude that the use of NOACs both in the acute phase and in the extended phase is equally effective to conventional therapy and associated with fewer major bleeding events, which make their use in patients at higher risk of recurrences safer.

Antiplatelet Therapy for Non-ST-Segment Elevation Myocardial Infarction in Complex "Real" Clinical Scenarios: A Consensus Document of the "Campania NSTEMI Study Group".

The incidence of ST-segment elevation myocardial infarction (STEMI) has significantly decreased. Conversely, the rate of non-STEMI (NSTEMI) has increased. Patients with NSTEMI have lower short-term mortality compared to patients with STEMI, whereas at long-term follow-up, the mortality becomes comparable. This might be due to the differences in baseline characteristics, including older age and a greater prevalence of comorbidities in the NSTEMI population. Although antithrombotic strategies used in patients with NSTEMI have been well studied in clinical trials and updated guidelines are available, patterns of use and outcomes in clinical practice are less well described. Thus, a panel of Italian cardiology experts assembled under the auspices of the "Campania NSTEMI Study Group" for comprehensive discussion and consensus development to provide practical recommendations, for both clinical and interventional cardiologists, regarding optimal management of antithrombotic therapy in patients with NSTEMI. This position article presents and discusses various clinical scenarios in patients with NSTEMI or unstable angina, including special subsets (eg, patients aged ≥85 years, patients with chronic renal disease or previous cerebrovascular events, and patients requiring triple therapy or long-term antithrombotic therapy), with the panel recommendations being provided for each scenario.

[ANMCO/SIC/SICI-GISE/SICCH Consensus document: Clinical approach to pharmacological pretreatment for patients undergoing myocardial revascularization]. / Documento di consenso ANMCO/SIC/SICI-GISE/SICCH: Approccio clinico al pretrattamento farmacologico in pazienti candidati a procedure di rivascolarizzazione miocardica.

The wide availability of drugs effective in reducing cardiovascular events and the use of myocardial revascularization have greatly improved the prognosis of patients with coronary artery disease. However, the combination of antithrombotic drugs to be administered before the exact knowledge of the coronary anatomy and before the consequent therapeutic strategy can, on one hand, allow to anticipate an optimal treatment but, on the other hand, may expose the patient to a bleeding risk not always necessary. In patients with ST-elevation acute coronary syndrome with an indication to primary angioplasty, the administration of unfractionated heparin and aspirin is considered the pre-procedural standard treatment. The upstream administration of an oral P2Y12 inhibitor, even if not supported by randomized controlled trials, appears reasonable in view of the very high likelihood of treatment with angioplasty. In patients with non-ST elevation acute coronary syndrome, in which it is not always chosen an invasive strategy, the occurrence of bleeding can significantly weigh on prognosis, even more than the theoretical benefit of pretreatment. Fondaparinux is the anticoagulant with the most favorable efficacy/safety profile. Antiplatelet pretreatment must be selective, guided by the ischemic risk conditions, the risk of bleeding and the time schedule for coronary angiography.In patients with stable coronary artery disease, generally treated with aspirin, pretreatment with clopidogrel is advisable in case of already scheduled angioplasty, and it appears reasonable in case of high likelihood, at least in patients at low bleeding risk. In patients candidate to surgical revascularization, aspirin is typically maintained and the oral P2Y12-inhibitor discontinued, with i.v. antiplatelet drug bridging in selected cases.Anti-ischemic drugs are useful in controlling symptoms, but they have no specific indications with regard to revascularization procedures. Statins showed protective effects on periprocedural damage and late clinical events, when administered early. Although randomized data are lacking, it seems reasonable their pre-procedural administration, due to potential advantages without significant adverse effects.

Contemporary antithrombotic strategies in patients with acute coronary syndromes managed without revascularization: insights from the EYESHOT study.

AIMS: Patients with acute coronary syndromes (ACSs) who are managed without coronary revascularization represent a mixed and understudied population that seems to receive suboptimal pharmacological treatment. METHODS AND RESULTS: We assessed patterns of antithrombotic therapies employed during the hospitalization and in-hospital clinical events of medically managed patients with ACS enrolled in the prospective, multicentre, nationwide EYESHOT (EmploYEd antithrombotic therapies in patients with acute coronary Syndromes HOspitalized in iTalian cardiac care units) registry. Among the 2585 consecutive ACS patients enrolled in EYESHOT, 783 (30.3%) did not receive any revascularization during hospital admission. Of these, 478 (61.0%) underwent coronary angiography (CA), whereas 305 (39.0%) did not. The median GRACE and CRUSADE risk scores were significantly higher among patients who did not undergo CA compared with those who did (180 vs. 145, P < 0.0001 and 50 vs. 33, P < 0.0001, respectively). Antithrombotic therapies employed during hospitalization significantly differ between patients who received CA and those who did not with unfractioned heparin and novel P2Y12 inhibitors more frequently used in the first group, and low-molecular-weight heparins and clopidogrel in the latter group. During the index hospitalization, patients who did not receive CA presented a higher incidence of ischaemic cerebrovascular events and of mortality compared with those who underwent CA (1.6 vs. 0.2%, P = 0.04 and 7.9 vs. 2.7%, P = 0.0009, respectively). CONCLUSION: Almost one-third of ACS patients are managed without revascularization during the index hospitalization. In this population, a lower use of recommended antiplatelet therapy and worse clinical outcome were observed in those who did not undergo CA when compared with those who did.
