Nutraceuticals in Chronic Coronary Syndromes: Preclinical Data and Translational Experiences.

Non-pharmacological treatments have always been considered important in the management of Chronic Coronary Syndromes. Nutraceuticals ("Nutrition" + "Pharmaceutical") could fall both under the definition of non-pharmacological treatment and pharmacological one or, probably more correctly, in the middle of these two kinds of therapies. However, the word “nutraceuticals” never appears in the latest guidelines on this issue. This is probably determined by the fact that evidences on this topic are scarce and most of the published articles are based on preclinical data while translational experiences are available only for some molecules. In this review we will focus on nutraceutical strategies that act on the ischemic myocardium itself and not only on the cardiovascular risk factors. As demonstrated by the important number of papers published in recent years, this is an evolving topic and evaluated substances principally act on two mechanisms (cardiac energetics and ischemia-reperfusion damage) that will be also reviewed.Electronic supplementary materialThe online version of this article (doi:10.1007/s40292-020-00416-8) contains supplementary material, which is available to authorized users.

Non-cardiovascular comorbidities in patients with chronic coronary syndromes (review) (2019 ESC Guidelines for the diagnosis and management of chronic coronary syndromes)

С areful evaluation of patient history, including of anginal symptoms, and evaluation of risk factors and manifestation of coronary artery disease (CAD), as well as proper physical examination and basic testing, are crucial for the diagnosis and management of chronic coronary syndrome(s) (CCS) and non-cardiovascular comorbidities. Anti-ischaemic treatment must be adapted to the individual patient based on comorbidites, co-administered therapies, expected tolerance and adherence, and patient preferences. The choice of anti-ischaemic drugs to treat chronic coronary sydromes should be adapted to the patient’s heart rate, blood pressure, and left-ventricular (LV) function. In patients with active cancer treatment decisions should based on life be expectancy, additional comorbidities such as thrombocytopenia, increased thrombosis propensity. and potential interactions between drugs used in CCS management and antineoplastic agents. In asymptomatic patients with diabetes mellitus, a periodic resting electrocardiogram is recommended for cardiovascular detection of conduction abnormalities, atrial fibrillation, and silent myocardial infarction. Recommendations for chronic kidney disease (CRD): use iodinated contrast agents is minimized in patients with severe CKD and preserved urine production to prevent further deterioration. It is recommended that particular attention is paid to side effects of drugs, intolerance, and overdosing in elderly patients with chronic coronary syndromes. Hormone replacement therapy is not recommended for risk reduction in post- menopausal women. Тransmyocardial revascularization is not recommended in patients with debilitating angina refractory to optimal medical and revascularization strategies.

Risk for Recurrent Cardiovascular Events and Expected Risk Reduction With Optimal Treatment 1 Year After an Acute Coronary Syndrome

According to the latest European Society of Cardiology Guidelines for the diagnosis and management of chronic coronary syndromes, patients who suffered an acute coronary syndrome fall into a chronic stable phase after 1 year. In these patients, the estimated 10-year risk for recurrent cardiovascular events varies considerably. We applied the SMART (Second Manifestations of Arterial Disease) risk score in 281 patients 1 year after an acute coronary syndrome to estimate the 10-year risk for recurrent cardiovascular events (subsequent nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death). We assessed the distribution of the estimated risk and the potential risk reduction that might be achieved with optimal guideline-directed management of modifiable risk factors (systolic blood pressure, low-density lipoprotein cholesterol, smoking, and body mass index). In our cohort, the median SMART score was 16.1% (interquartile range [IQR] 9.7 to 27.3), particularly increased in patients with older age, diabetes, polyvascular disease or chronic kidney disease (median 28.6%, IQR 20.8 to 52.9; 23.8%, 4.8 to 41.6; 29.4%, 18.8 to 49.7; 53.8%, 26.5 to 71.6, respectively). If all modifiable risk factors met guideline-recommended targets, the median SMART risk score would be 9.6% (IQR 6.3 to 20.9), with 51% of the patients at a 10-year risk <10%, while 11% and 15% at 20% to 30% and >30% risk, respectively. In conclusion, the SMART score had a wide distribution in patients with chronic coronary syndromes. A quarter of patients remained at a >20% 10-year risk, even with optimal risk factor management, clearly underlining that residual risk is an unmet clinical challenge.

Chronic stable angina (CCS) is the most prevalent symptom of ischaemic heart disease and its management is a priority. CCS are defined by the different evolutionary phases of CAD, excluding situations in which an acute coronary artery thrombosis dominates the clinical presentation (i.e ACS). The most frequently encountered clinical scenarios in patients with suspected or established CCS are: 1) CAD patients with suspected CAD and ''stable'' anginal symptoms, and/or dyspnoea; 2) patients with new onset of heart failure or left ventricular dysfunction and suspected CAD;3) asymptomatic and symptomatic patients with stabilized symptoms &lt;1 year after ASC or patients with recent revascularization;4) asymptomatic and symptomatic patients &gt; 1 year after initial diagnosis or revascularization; 5) patients with angina and suspected vasospastic or microvascular disease; 6) and asymptomatic subjects in whom CAD is screening. Т h е new technologies improve the results of treatment of these patients. Authors used determinants of the clinical likelihood of obstructive coronary artery disease and suggested stepwise strategy for long-term anti-ischemic drug therapy in patients with CCS and specific baseline characteristics. Current guidelines recommend pharmacological therapy with drugs classified as being first line (beta blockers, calcium channel blockers, short acting nitrates) or second line (long-acting nitrate, ivabradine, nicorandil, ranolazine and trimetazidine). Second line drugs are indicated for patients who have contraindications to first line agents, do not tolerante them or remain symptomatic. Patients with angina pectoris due coronary artery disease should also detreated with low dose aspirin and a statin. The demonstrated effect of the drugs include disease clinical manifestation, reduction and decrease of cardiovascular incidence and mortality rates.

ESC 2019 guidelines for the diagnosis and management of chronic coronary syndromes : Recommendations for cardiovascular imaging.

The European Society of Cardiology (ESC) has recently published new guidelines on the diagnosis and management of chronic coronary syndromes (CCS). Due to variable symptoms, objective tests are often necessary to confirm the diagnosis, exclude alternative diagnoses, and assess the severity of underlying disease. This review provides a summary of the main diagnostic strategies listed in the guidelines for evaluation of patients suspected of having obstructive coronary artery disease (CAD). Based on data from contemporary cohorts of patients referred for diagnostic testing, the pre-test probabilities of obstructive CAD based on age, sex, and symptoms have been adjusted substantially downward compared with the previous guidelines. Further, a new concept of “clinical likelihood of CAD” was introduced accounting for the impact of various risk factors and modifiers on the pre-test probability. Noninvasive functional imaging for myocardial ischemia, coronary computed tomography angiography, or invasive coronary angiography combined with functional evaluation is recommended as the initial strategy to diagnose CAD in symptomatic patients, unless obstructive CAD can be excluded by clinical assessment alone. When available, imaging tests are recommended as noninvasive modalities instead of exercise electrocardiograms.

Guidelines for the Diagnosis and Management of Chronic Coronary Syndromes in Primary Health Care - the Issue of Acceptability for the Russian Federation

In 2019, the European Society for Cardiology (ESC) published guidelines with a new term, "chronic coronary syndromes" (CCS). These guidelines presented 6 clinical scenarios, which are most common in outpatient practice. The diagnostic approach described in these guidelines shifts from the standardization to the rationality of individualized solutions on using various diagnostic methods. The diagnostic approach suggested in the ESC guidelines requires extensive medical discussion and consensus because this will definitely entail a) further increase in indexes that reflect the morbidity of ischemic heart disease (IHD) due to unconfirmed diagnoses and b) administration of unreasoned therapy. This article presents statements of the guidelines, which cannot be automatically transmitted to the existing medical practice and should be discussed and adjusted by experts of the Russian Society of Cardiology.

Non-invasive Imaging of Chronic Coronary Syndromes - CT Coronary Angiography and Stress Perfusion Cardiac MRI

Non-invasive Imaging of Chronic Coronary Syndromes - CT Coronary Angiography and Stress Perfusion Cardiac MRI Abstract. Coronary artery disease (CAD) is amongst the leading causes of death worldwide. The European Society of Cardiology (ESC) has recently published new guidelines on diagnosis and management of chronic coronary syndromes. These guidelines emphasize the use of non-invasive imaging tests to assess CAD. Compared to previous versions of these guidelines, the pre-test probabilities of CAD based on age, sex and symptoms have been adjusted downward. Unless obstructive CAD can be excluded by clinical assessment alone, various strategies to diagnose CAD in symptomatic patients may be used: coronary CT angiography, non-invasive functional imaging for myocardial ischaemia, or invasive coronary angiography combined with functional evaluation. This review summarizes strengths and weaknesses of non-invasive cardiac imaging modalities with emphasize on coronary CT angiography and stress perfusion cardiac magnetic resonance (CMR) imaging.

Direct-acting Anticoagulants in Chronic Coronary Syndromes

Direct-acting oral anticoagulants (DOACs) are easier to use, safer than and as effective as vitamin K antagonists (VKA) in the treatment of non-valvular AF (NVAF). Because of their favourable safety profile and easier use than VKAs, DOACs as anti-thrombotic therapy may have a role in the management of chronic coronary syndromes (CCS). To date, few studies have evaluated DOACs in this setting. Initial studies have focused on patients receiving DOACs for NVAF undergoing acute or elective percutaneous coronary intervention who additionally require dual antiplatelet therapy (DAPT). Rivaroxaban 15 mg once daily plus a P2Y12 inhibitor compared with a VKA regimen was associated with a reduction of bleedings (HR 0.59; 95% CI [0.47–0.76]; p<0.001). Rivaroxaban 2.5 mg twice daily plus DAPT up to 12 months followed by rivaroxaban 15 mg once daily plus P2Y12 inhibitor showed similar results. Dabigatran 110 mg twice daily plus a P2Y12 inhibitor versus a VKA regimen was associated with a reduction of bleedings (HR 0.52; 95% CI [0.42–0.63]; p<0.001), after a mean follow-up of 14 months. A dabigatran 150 mg regimen showed similar results. Apixaban 5 mg twice daily plus a P2Y12 inhibitor versus a VKA regimen confirmed at 6 months the safety of DOACs with a reduction of bleedings (HR 0.69; 95% CI [0.58–0.81]; p<0.001 for non-inferiority and superiority). Edoxaban 60 mg once daily plus a P2Y12 inhibitor was non-inferior to a VKA regimen on bleeding outcomes (major bleeding or non-major clinically relevant non-major bleeding) after a 12-month follow-up (HR 0.83; 95% CI [0.65–1.05]; p=0.001 for non-inferiority; p=0.1154 for superiority). Meta-analysis of these four trials confirmed the safety of DOACs regarding bleeding outcomes, but showed a trend toward stent thrombosis for dual antithrombotic therapy using DOACs versus triple antithrombotic therapy using VKAs. DOACs may show promise in the management of high-risk patients with chronic coronary syndromes. In these patients, rivaroxaban 2.5 mg twice daily in addition to aspirin was shown to reduce the composite outcome of cardiovascular death, stroke or MI compared to aspirin alone (HR 0.76; 95% CI [0.66–0.86]; p<0.001). All-cause death, cardiovascular death and stroke were also significantly lower. This benefit was at the cost of an increase in non-fatal bleeding.

Cardiac magnetic resonance imaging to detect ischemia in chronic coronary syndromes: state of the art.

The new 2019 European Society of Cardiology guidelines for the diagnosis and management of chronic coronary syndromes emphasize the role of noninvasive functional imaging of myocardial ischemia in diagnosing coronary artery disease to guide decision making regarding revascularization. Cardiac magnetic resonance imaging (CMR) stands out relative to other imaging modalities given its high safety profile, absence of ionizing radiation, and its versatility in encoding various image contrasts. It also allows an assessment of myocardial function, ischemia, and viability as well as permits tissue characterization including detection of edema in a single examination. In recent years, a number of meta‑analyses and studies considering the role of CMR for detecting ischemia have been published. The recent multicenter randomized MR‑INFORM trial has demonstrated the clinical utility of CMR in patients with stable angina and cardiovascular risk factors. This landmark study has proved that a perfusion CMR‑based strategy leads to a lower number of revascularizations while being noninferior to an invasive coronary angiography with fractional flow reserve-guided therapy in terms of major adverse cardiac events at 1 year. In light of recent and future technical improvements, CMR will become increasingly important in the assessment of myocardial ischemia in patients with chronic coronary syndromes.

Imaging in ESC clinical guidelines: chronic coronary syndromes.

The European Society of Cardiology (ESC) has recently published new guidelines on the diagnosis and management of chronic coronary syndromes (CCS). The 2019 guideline identified six common clinical scenarios of CCS defined by the different evolutionary phases of coronary artery disease (CAD), excluding the situations in which an acute coronary event, often with coronary thrombus formation, dominates the clinical presentation. This review aims at providing a summary of novel or revised concepts in the guidelines together with the recent data underlying the major changes on the use of cardiac imaging in patients with suspected or known CCS. Based on data from contemporary cohorts of patients referred for diagnostic testing, the pre-test probabilities of CAD based on age, sex and symptoms have been adjusted substantially downward as compared with 2013 ESC guidelines. Further, the impact of various risk factors and modifiers on the pre-test probability was highlighted and a new concept of 'Clinical likelihood of CAD' was introduced. Recommendations regarding diagnostic tests to establish or rule-out obstructive CAD have been updated with recent data on their diagnostic performance in different patient groups and impact on patient outcome. As the initial strategy to diagnose CAD in symptomatic patients, non-invasive functional imaging for myocardial ischaemia, coronary computed tomography angiography or invasive coronary angiography combined with functional evaluation may be used, unless obstructive CAD can be excluded by clinical assessment alone. When available, imaging tests instead of the exercise electrocardiogram are recommended when following the non-invasive diagnostic strategy.

European Society of Cardiology Chronic Coronary Syndromes Guidelines Review

New guidelines for the diagnosis and management of chronic coronary syndromes (CCS)1were released during the 2019 European Society of Cardiology (ESC) Congress. The new guidelines were discussed in multiple sessions with different formats across the congress; this review summarises some of the discussion among experts at the congress around what the new guidelines mean for the way they manage their patients with respect to antithrombotic treatment. A significant change in the new guidelines versus previous guidelines published in 20132is an update in nomenclature from ‘stable’ coronary artery disease (CAD) to chronic coronary syndromes, to reflect the fact that patients with CCS are at continuous risk of heart attacks, strokes, and death. This highlights the need for effective preventive therapy to protect against these thrombotic events and maintain a state of relative stability in patients with CCS. To this end, a new recommendation in the 2019 guidelines is to consider intensification of antithrombotic therapy, using aspirin plus another antithrombotic agent, to provide enhanced long-term protection for patients with CCS at high risk of ischaemic events. This review places the new guideline recommendations in clinical perspective, including thorough presentations of case studies to illustrate how patients at greatest risk of ischaemic events can be identified, and treatment stratified accordingly. These case studies highlight the role of dual pathway inhibition (DPI) in managing CCS patients with the greatest need for cardiovascular protection, who are likely to derive the greatest benefit from this treatment strategy.

Coronary artery disease (CAD) is a pathological process characterized by atherosclerotic plaque accumulation in the epicardial arteries, whether obstructive or non-obstructive. This process can be modified by lifestyle adjustments, pharmacological therapies, and invasive interventions designed to achieve disease stabilization or regression. The disease can have long, stable periods but can also become unstable at any time, typically due to an acute atherothrombotic event caused by plaque rupture or erosion. However, the disease is chronic, most often progressive, and hence serious, even in clinically apparently silent periods. The dynamic nature of the CAD process results in various clinical presentations, which can be conveniently categorized as either acute coronary syndromes (ACS) or chronic coronary syndromes (CCS). The Guidelines presented here refer to the management of patients with CCS. The natural history of CCS is illustrated in Figure 1.
