Management of acute coronary syndromes in older adults.

Older patients are underrepresented in prospective studies and randomized clinical trials of acute coronary syndromes (ACS). Over the last decade, a few specific trials have been conducted in this population, allowing more evidence-based management. Older adults are a heterogeneous, complex, and high-risk group whose management requires a multidimensional clinical approach beyond coronary anatomic variables. This review focuses on available data informing evidence-based interventional and pharmacological approaches for older adults with ACS, including guideline-directed management. Overall, an invasive approach appears to demonstrate a better benefit-risk ratio compared to a conservative one across the ACS spectrum, even considering patients' clinical complexity and multiple comorbidities. Conversely, more powerful strategies of antithrombotic therapy for secondary prevention have been associated with increased bleeding events and no benefit in terms of mortality reduction. An interdisciplinary evaluation with geriatric assessment should always be considered to achieve a holistic approach and optimize any treatment on the basis of the underlying biological vulnerability.

Gastroprotection in patients on antiplatelet and/or anticoagulant therapy: a position paper of National Association of Hospital Cardiologists (ANMCO) and the Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO).

Aspirin and P2Y12 receptor antagonists are widely used across the spectrum of cardiovascular and cerebrovascular diseases. Gastrointestinal complications, including ulcer and bleeding, are relatively common during antiplatelet treatment and, therefore, concomitant proton pump inhibitor (PPI) treatment is often prescribed. However, potential increased risk of cardiovascular events has been suggested for PPIs, and, in recent years, it has been discussed whether these drugs may reduce the cardiovascular protection by aspirin and, even more so, clopidogrel. Indeed, pharmacodynamic and pharmacokinetic studies suggested an interaction through hepatic CYP2C19 between PPIs and clopidogrel, which could translate into clinical inefficacy, leading to higher rates of cardiovascular events. The FDA and the EMA sent a warning in 2010 discouraging the concomitant use of clopidogrel with omeprazole or esomeprazole. In addition, whether the use of PPIs may affect the clinical efficacy of the new P2Y12 receptor antagonists, ticagrelor and prasugrel, remains less known. According to current guidelines, PPIs in combination with antiplatelet treatment are recommended in patients with risk factors for gastrointestinal bleeding, including advanced age, concurrent use of anticoagulants, steroids or non-steroidal anti-inflammatory drugs, and Helicobacter pylori infection. Like vitamin K antagonists (VKAs), DOACs can determine gastrointestinal bleeding. Results from both randomized clinical trials and observational studies suggest that high-dose dabigatran (150 mg bid), rivaroxaban and high-dose edoxaban (60 mg daily) are associated with a higher risk of GI bleeding as compared with apixaban and warfarin. In patients taking oral anticoagulant with GI risk factor, PPI could be recommended, even if usefulness of PPIs in these patients deserves further data. Helicobacter pylori should always be searched, and treated, in patients with history of peptic ulcer disease (with or without complication). Given the large number of patients treated with antithrombotic drugs and PPIs, even a minor reduction of platelet inhibition or anticoagulant effect potentially carries a considerable clinical impact. The present joint statement by ANMCO and AIGO summarizes the current knowledge regarding the widespread use of platelet inhibitors, anticoagulants, and PPIs in combination. Moreover, it outlines evidence supporting or opposing drug interactions between these drugs and discusses consequent clinical implications.

[Antithrombotic therapy after acute coronary syndromes: is it possible to identify the PEGASUS and COMPASS patient?] / Terapia antitrombotica dopo sindrome coronarica acuta: come identificare il paziente PEGASUS ed il paziente COMPASS.

Although having different rationales and purposes, the PEGASUS-TIMI 54 and COMPASS trials present various points of contact and, especially after the first recommended year of dual antiplatelet therapy (DAPT) from an acute coronary syndrome, pose the clinical question of whether DAPT should be prolonged (PEGASUS strategy) or aspirin should be maintained by combining rivaroxaban 2.5 mg bid (COMPASS strategy). In this review, we try to trace the PEGASUS and COMPASS patient's profile by analyzing the design of each study with their inclusion/exclusion criteria, the main subanalyses and the real-world studies recently published in this setting.

Management of atrial fibrillation in the emergency room and in the cardiology ward: the BLITZ AF study.

AIMS: To assess the number of admissions to the emergency room (ER) of patients with atrial fibrillation (AF) or atrial flutter (af) and their subsequent management. To evaluate the clinical profile and the use of antithrombotics and antiarrhythmic therapy in patients with AF admitted to cardiology wards. METHODS AND RESULTS: BLITZ-AF is a multicentre, observational study conducted in 154 centres on patients with AF/af. In each centre, data were collected, retrospectively for 4 weeks in ER and prospectively for 12 weeks in cardiology wards. In ER, there were 6275 admissions. Atrial fibrillation was the main diagnosis in 52.9% of the cases, af in 5.9%. Atrial fibrillation represented 1.0% of all ER admissions and 1.7% of all hospital admissions. A cardioversion has been performed in nearly 25% of the cases. Out of 4126 patients, 52.2% were admitted in cardiology ward; mean age was 74 ± 11 years, 41% were females. Patients with non-valvular AF were 3848 (93.3%); CHA2DS2-VASc score was ≥2 in 87.4%. Cardioversion was attempted in 38.8% of the patients. In-hospital mortality was 1.2%. At discharge, 42.6% of the patients were treated with vitamin K antagonists, 39.5% with direct oral anticoagulants, 13.6% with other antithrombotic drugs, and 4.2% did not take any antithrombotic agent. Rate control strategy was pursued in 47.2%, rhythm control in 44.0%, 45.6% were discharged in sinus rhythm. CONCLUSION: Atrial fibrillation still represents a significant burden on health care system. Oral anticoagulant use increased over time even if compliance with guidelines, with respect to prevention of the risk of stroke, remains suboptimal.

[Clinical competence in intensive cardiac care units: from practical needs to training programs]. / Le competenze cliniche del cardiologo di unità di terapia intensiva cardiologica: dalle esigenze pratiche ai progetti formativi.

Since the early 1970s, intensive cardiac care is applied in coronary care units (CCUs), initially developed to treat lethal arrhythmias in patients with acute myocardial infarction. In the last decades, treatments offered within the CCUs have greatly expanded. Thus, these units have been called intensive cardiac care units (ICCUs) to reflect such evolution of care and the different epidemiology of patients admitted (subjects with acute coronary syndromes, acute and advanced heart failure, rhythm disturbances or severe valve dysfunction). At the same time, new drugs have become available but also different diagnostic, interventional and therapeutic procedures have been developed, resulting in better patient treatment and improved outcomes. These new devices require a high degree of specialization and specific skills that not every cardiologist is always used to. Consequently, specific training programs on intensive cardiac care for cardiologists working in ICCUs are clearly warranted. The present paper describes the advanced training programs on intensive cardiac care endorsed by the European Society of Cardiology and the Italian Association of Hospital Cardiologists (ANMCO). Both projects aim at improving current knowledge and skills of intensive cardiologists on specific pharmacologic and technical procedures, extending the competence of trained cardiologists to the management of critically ill cardiac patients, and uniforming the quality of care in any ICCU.

Effects of glucose-insulin-potassium infusion on myocardial perfusion and left ventricular remodeling in patients treated with primary angioplasty for ST-elevation acute myocardial infarction.

The role of glucose-insulin-potassium (GIK) infusion in the management of acute coronary syndrome is controversial. Limited data are available on the effects of adjunctive high-dose GIK (30% glucose, 50 IU of insulin, 80 mEq of potassium chloride infused at 1.5 ml/kg/hour over 24 hours) on myocardial perfusion and left ventricular (LV) remodeling in patients treated with primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction. In this prospective study, 73 patients were randomized to receive GIK infusion (n = 40) or saline (placebo, n = 33) in addition to standard therapy. The primary end points were myocardial perfusion after PCI and LV remodeling at 6 months. Thrombolysis In Myocardial Infarction frame count and myocardial blush grade were evaluated before and after reperfusion treatment. LV end-diastolic and end-systolic volumes, ejection fraction, and wall motion score index were assessed in each patient after PCI and after 6 months. Although no differences in final Thrombolysis In Myocardial Infarction flow were observed between the 2 groups, myocardial blush grade 3 was more frequently achieved in the GIK group (p <0.05). At 6 months, ventricular remodeling was more often observed in the control group (24% vs 3%, p <0.05). In conclusion, GIK infusion in adjunct to primary PCI in patients with ST-segment elevation myocardial infarction was safe, improved myocardial perfusion after revascularization, and was associated with less LV remodeling at follow-up.

Reassessment of dobutamine, dopamine, and milrinone in the management of acute heart failure syndromes.

The appropriate role of intravenous inodilator therapy (inotropic agents with vasodilator properties) in the management of acute heart failure syndromes (AHFS) has long been a subject of controversy, mainly because of the lack of prospective, placebo-controlled trials and a lack of alternative therapies. The use of intravenous inodilator infusions, however, remains common, but highly variable. As new options emerge for the treatment of AHFS, the available information should be reviewed to determine which approaches are supported by evidence, which are used empirically without evidence, and which should be considered inappropriate. For these purposes, we reviewed data available from randomized controlled trials on short-term, intermittent, and long-term use of intravenous inodilator agents (dobutamine, dopamine, and milrinone) in AHFS. Randomized controlled trials failed to show benefits with current medications and suggested that acute, intermittent, or continuous use of inodilator infusions may increase morbidity and mortality in patients with AHFS. Their use should be restricted to patients who are hypotensive as a result of low cardiac output despite a high left ventricular filling pressure.
