2021 ACC/AHA/SCAI Guideline for Coronary Artery Revascularization: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines.
AIM
The guideline for coronary artery revascularization replaces the 2011 coronary artery bypass graft surgery and the 2011 and 2015 percutaneous coronary intervention guidelines, providing a patient-centric approach to guide clinicians in the treatment of patients with significant coronary artery disease undergoing coronary revascularization as well as the supporting documentation to encourage their use.
METHODS
A comprehensive literature search was conducted from May 2019 to September 2019, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, CINHL Complete, and other relevant databases. Additional relevant studies, published through May 2021, were also considered.
STRUCTURE
Coronary artery disease remains a leading cause of morbidity and mortality globally. Coronary revascularization is an important therapeutic option when managing patients with coronary artery disease. The 2021 coronary artery revascularization guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with coronary artery disease who are being considered for coronary revascularization, with the intent to improve quality of care and align with patients' interests.

Review
The 'epidemic' of heart failure seems to be changing, but precise prevalence estimates of heart failure and left ventricular dysfunction (LVD) in older adults, based on adequate echocardiographic assessment, are scarce. Systematic reviews including recent studies on the prevalence of heart failure and LVD are lacking. We aimed to assess the trends in the prevalence of LVD, and heart failure with reduced (HFrEF) and preserved ejection fraction (HFpEF) in the older population at large. A systematic electronic search of the databases Medline and Embase was performed. Studies that reported prevalence estimates in community-dwelling people ≥60 years old were included if echocardiography was used to establish the diagnosis. In total, 28 articles from 25 different study populations were included. The median prevalence of systolic and 'isolated' diastolic LVD was 5.5% (range 3.3-9.2%) and 36.0% (range 15.8-52.8%), respectively. A peak in systolic dysfunction prevalence seems to have occurred between 1995 and 2000. 'All type' heart failure had a median prevalence rate of 11.8% (range 4.7-13.3%), with fairly stable rates in the last decade and with HFpEF being more common than HFrEF [median prevalence 4.9% (range 3.8-7.4%) and 3.3% (range 2.4-5.8%), respectively]. Both LVD and heart failure remain common in the older population at large. The prevalence of diastolic dysfunction is on the rise and currently higher than that of systolic dysfunction. The prevalence of the latter seems to have decreased in the 21st century.

Review
In modern cardiology, sodium-glucose cotransporter 2 (SGLT2) inhibitors are critical components of heart failure (HF) treatment algorithms and exert their effects primarily by preventing glucose reabsorption and facilitating its urinary excretion. The objective was to systematically review randomized controlled trials (RCTs) assessing the effects of SGLT2 inhibitors, particularly canagliflozin, empagliflozin, dapagliflozin, ertugliflozin, sotagliflozin (dual SGLT inhibitor), and their use in HF. Systematic searches of PubMed/Medline, The Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov databases were performed. There were no restrictions imposed on the date and status of publication; however, there were restrictions on language for the searched studies. A total of 1139 records were identified in the bibliographic searches from both databases and the register of choice for this systematic review. Following duplicate removal, screening for titles and abstracts, and thorough assessment of full-text articles, 12 RCTs met the inclusion criteria. Altogether, 83 878 patients were included in this review. Among the included studies, two RCTs, with six respective reports, investigated canagliflozin, four RCTs with 13 derived reports investigated dapagliflozin, three RCTs with 12 separate reports studied the effects of empagliflozin, one RCT and its three respective reports assessed ertugliflozin's effects, and two RCTs with one added report investigated the dual inhibitor sotagliflozin. Pooled meta-analytic effects of SGLT2 inhibitors were as follows: on atrial fibrillation odds ratio (OR) = 0.83, 95% confidence interval (CI): 0.68-1.01, prediction interval (PI): 0.57-1.19; on HF hospitalization OR = 0.69, 95% CI: 0.60-0.78, PI: 0.60-0.78; on cardiovascular death OR = 0.82, 95% CI: 0.58-1.15, PI: 0.42-1.60; and on major adverse cardiovascular events OR = 0.90, 95% CI: 0.77-1.06, PI: 0.71-1.15. SGLT2 inhibitors significantly improve the quality of life in HF patients. Their beneficial effects on HF, especially in left ventricular dysfunction, have made their use possible irrespective of diabetes mellitus or atrial fibrillation status.

Meta-Analysis
AIMS
An algorithm for non-invasive diagnosis of amyloid transthyretin cardiac amyloidosis (ATTR-CA) and novel disease-modifying therapies have prompted an active search for CA. We examined the prevalence of CA in different settings based on literature data.
METHODS AND RESULTS
We performed a systematic search for screening studies on CA, focusing on the prevalence, sex and age distribution in different clinical settings. The prevalence of CA in different settings was as follows: bone scintigraphy for non-cardiac reasons (n = 5 studies), 1% (95% confidence interval [CI] 0%-1%); heart failure with preserved ejection fraction (n = 6), 12% (95% CI 6%-20%); heart failure with reduced or mildly reduced ejection fraction (n = 2), 10% (95% CI 6%-15%); conduction disorders warranting pacemaker implantation (n = 1), 2% (95% CI 0%-4%); surgery for carpal tunnel syndrome (n = 3), 7% (95% CI 5%-10%); hypertrophic cardiomyopathy phenotype (n = 2), 7% (95% CI 5%-9%); severe aortic stenosis (n = 7), 8% (95% CI 5%-13%); autopsy series of 'unselected' elderly individuals (n = 4), 21% (95% CI 7%-39%). The average age of CA patients in the different settings ranged from 74 to 90 years, and the percentage of men from 50% to 100%. Many patients had ATTR-CA, but the average percentage of patients with amyloid light-chain (AL) CA was up to 18%.
CONCLUSIONS
Searching for CA in specific settings allows to identify a relatively high number of cases who may be eligible for treatment if the diagnosis is unequivocal. ATTR-CA accounts for many cases of CA across the different settings, but AL-CA is not infrequent. Median age at diagnosis falls in the eighth or ninth decades, and many patients diagnosed with CA are women.

Beta-adrenoreceptor antagonist (beta-blocker) poisoning is a common overdose which can lead to significant morbidity and mortality. To evaluate the effects of treatments for beta-adrenoreceptor antagonist poisoning. Searches were conducted across MEDLINE (1946-26 November 2019, Ovid); Embase (1974-26 November 2019, Ovid); and the Cochrane Central Register of Controlled Trials (CENTRAL, to 26 November 2019) utilising a combination of subject headings and free text. The search strategy identified 15, 553 citations. Two reviewers screened titles and abstracts prior to selecting 141 articles (Kappa on articles included = 0.982, 95% CI 0.980-0.985). Primary outcomes included mortality and improvement in haemodynamic parameters (e.g., heart rate, blood pressure or a composite measure able to quantitate a haemodynamic response). The risk of bias was high for all interventions. Fifteen case reports described the administration of activated charcoal and five detailed the use of gastric lavage. As there was concurrent utilisation of multiple interventions, it was difficult to draw definitive conclusions regarding the relative contribution of these interventions to mortality or survival. The use of catecholamines in treating beta-blocker toxicity was reported in 16 case reports, 3 case series and 2 animal studies. These agents most likely provided a survival benefit and improved haemodynamics. Multiple intravenous boluses of atropine were associated with improvement in heart rate and blood pressure in one case report. Intravenous calcium was associated with an improvement in haemodynamics in three out of six case reports but in association with multiple other therapies as well as in two animal studies. The use of this therapy was associated with mortality benefit in 10 case series. Two case reports showed clear haemodynamic improvement in a timeframe consistent with insulin administration (bolus then continuous infusion). Maintenance dosing ranged from 1 to 10 units/kg/h of insulin. However, it is unclear whether high-dose insulin euglycaemic therapy improved haemodynamic response above catecholamines and other inotropic agents in humans. Hypoglycaemia and hypokalemia were commonly observed adverse effects. Glucagon was associated with minor improvements in haemodynamics through an increase in heart rate in two cases series, nine case reports and five animal studies. Four case reports reported an association with improvement in haemodynamics following administration of methylene blue but in the setting of co-ingestion with amlodipine. There was variable response to intravenous lipid emulsion therapy reported in 10 case series, 5 animal studies and 21 case reports. There were four case reports showing variable response to lignocaine in arrhythmias secondary to beta-blocker toxicity. Fructose diphosphate, levosimendan and amrinone did not provide a mortality or significant haemodynamic benefit in three animal studies and nine case reports. . Veno-arterial extracorporeal membrane oxygenation was associated with improved survival in patients with severe cardiogenic shock or cardiac arrest in an observational study and four cases series. The evidence of four case reports suggest haemodialysis may assist in the management of massive overdose of specific water-soluble beta-blockers (e.g., atenolol) by improving elimination; however, a survival or haemodynamic benefit was not established. One case series and a single case report showed the utility of temporary overdrive cardiac pacing to prevent arrhythmias in sotalol toxicity. Catecholamines, vasopressors, high-dose insulin euglycaemic therapy and veno-arterial extracorporeal membrane oxygenation were associated with reduced mortality. However, it must be acknowledged that multiple treatments were often given simultaneously. Haemodynamic improvements in blood pressure and cardiac output were seen with the use of catecholamines, vasopressin and high-dose insulin euglycaemic therapy. Evidence for treatment recommendations is almost entirely drawn from very low- to low-quality studies and subject to bias. However, it is reasonable to have a graduated response to cardiovascular instability beginning with intravenous fluids, commencement of a single or a combination of catecholamine inotropes and vasopressors depending upon the type of haemodynamic compromise (bradycardia, left ventricular dysfunction, vasodilation). High-dose insulin euglycaemic therapy can be introduced as an adjunctive inotrope and lastly, more invasive methods such as veno-arterial extracorporeal membrane oxygenation should be considered in cases unresponsive to other therapies.

INTRODUCTION/AIMS
Prognostic factors in Duchenne muscular dystrophy (DMD) predict the disease course and may help individualize patient care. The aim was to summarize the evidence on prognostic factors that may support treatment decisions.
METHODS
We searched six databases for prospective studies that each included ≥50 DMD patients with a minimum follow-up of 1 y. Primary outcomes were age at loss of ambulation (LoA), pulmonary function (forced vital capacity percent of predicted, FVC%p), and heart failure.
RESULTS
Out of 5074 references, 59 studies were analyzed. Corticosteroid use was associated with a delayed LoA (pooled effect hazard ratio [HR] 0.42, 95% confidence interval [CI] 0.23-0.75, I2 94%), better pulmonary function tests (higher peak FVC%, prolonged time with FVC%p > 50%, and reduced need for assisted ventilation) and delayed cardiomyopathy. Longer corticosteroid treatment was associated with later LoA (>1 y compared to <1 y; pooled HR: 0.50, 95% CI 0.27-0.90) and early treatment start (aged <5 y) may be associated with early cardiomyopathy and higher fracture risk. Genotype appeared to be an independent driver of LoA in some studies. Higher baseline physical function tests (e.g., 6-minute walk test) were associated with delayed LoA. Left ventricular dysfunction and FVC <1 L increased and the use of angiotensin-converting enzyme (ACE) inhibitors reduced the risk of heart failure and death. Fusion surgery in scoliosis may potentially preserve pulmonary function.
DISCUSSION
Prognostic factors that may inform clinical decisions include age at corticosteroid treatment initiation and treatment duration, ACE-inhibitor use, baseline physical function tests, pulmonary function, and cardiac dysfunction.

Meta-Analysis
Assessment of Prognostic Value of Left Ventricular Global Longitudinal Strain for Early Prediction of Chemotherapy-Induced Cardiotoxicity: A Systematic Review and Meta-analysis.
IMPORTANCE
Echocardiographic left ventricular global longitudinal strain (GLS) detects early subclinical ventricular dysfunction and can be used in patients receiving potentially cardiotoxic chemotherapy. A meta-analysis of the prognostic value of GLS for cancer therapy-related cardiac dysfunction (CTRCD) has not been performed, to our knowledge.
OBJECTIVE
To explore the prognostic value of GLS for the prediction of CTRCD.
DATA SOURCES
Systematic search of the MEDLINE, Embase, Scopus, and the Cochrane Library databases from database inception to June 1, 2018.
STUDY SELECTION
Cohort studies assessing the prognostic or discriminatory performance of GLS before or during chemotherapy for subsequent CTRCD.
DATA EXTRACTION AND SYNTHESIS
Random-effects meta-analysis and hierarchical summary receiver operating characteristic curves (HSROCs) were used to summarize the prognostic and discriminatory performance of different GLS indices. Publication bias was assessed using the Egger test, and meta-regression was performed to assess sources of heterogeneity.
MAIN OUTCOMES AND MEASURES
The primary outcome was CTRCD, defined as a clinically significant change in left ventricular ejection fraction with or without new-onset heart failure symptoms.
RESULTS
Analysis included 21 studies comprising 1782 patients with cancer, including breast cancer, hematologic malignancies, or sarcomas, treated with anthracyclines with or without trastuzumab. The incidence of CTRCD ranged from 9.3% to 43.8% over a mean follow-up of 4.2 to 23.0 months (pooled incidence, 21.0%). For active treatment absolute GLS (9 studies), the high-risk cutoff values ranged from -21.0% to -13.8%, with worse GLS associated with a higher CTRCD risk (odds ratio, 12.27; 95% CI, 7.73-19.47; area under the HSROC, 0.86; 95% CI, 0.83-0.89). For relative changes vs a baseline value (9 studies), cutoff values ranged from 2.3% to 15.9%, with a greater decrease linked to a 16-fold higher risk of CTRCD (odds ratio, 15.82; 95% CI, 5.84-42.85; area under the HSROC, 0.86; 95% CI, 0.83-0.89). Both indices showed significant publication bias. Meta-regression identified differences in sample size and CTRCD definition but not GLS cutoff value as significant sources of interstudy heterogeneity.
CONCLUSIONS AND RELEVANCE
In this meta-analysis, measurement of GLS after initiation of potentially cardiotoxic chemotherapy with anthracyclines with or without trastuzumab had good prognostic performance for subsequent CTRCD. However, risk of bias in the original studies, publication bias, and limited data on the incremental value of GLS and its optimal cutoff values highlight the need for larger prospective multicenter studies.

Meta-Analysis
BACKGROUND
Myocardial infarction with nonobstructive coronary arteries (MINOCA) is common in current clinical practice. Cardiac magnetic resonance (CMR) plays an important role in its management and is increasingly recommended by all the current guidelines. However, the prognostic value of CMR in patients with MINOCA is still undetermined.
OBJECTIVES
The purpose of this study was to determine the diagnostic and prognostic value of CMR in the management of patients with MINOCA.
METHODS
A systematic review was performed to identify studies reporting the results of CMR findings in patients with MINOCA. Random effects models were used to determine the prevalence of different disease entities: myocarditis, myocardial infarction (MI), or takotsubo syndrome. Pooled odds ratios (ORs) and 95% CIs were calculated to evaluate the prognostic value of CMR diagnosis in the subgroup of studies that reported clinical outcomes.
RESULTS
A total of 26 studies comprising 3,624 patients were included. The mean age was 54.2 ± 5.3 years, and 56% were men. MINOCA was confirmed in only 22% (95% CI: 0.17-0.26) of the cases and 68% of patients with initial MINOCA were reclassified after the CMR assessment. The pooled prevalence of myocarditis was 31% (95% CI: 0.25-0.39), and takotsubo syndrome 10% (95% CI: 0.06-0.12). In a subgroup analysis of 5 studies (770 patients) that reported clinical outcomes, CMR diagnosis of confirmed MI was associated with an increased risk of major adverse cardiovascular events (pooled OR: 2.40; 95% CI: 1.60-3.59).
CONCLUSIONS
In patients with MINOCA, CMR has been demonstrated to add an important diagnostic and prognostic value, proving to be crucial for the diagnosis of this condition. Sixty-eight percent of patients with initial MINOCA were reclassified after the CMR evaluation. CMR-confirmed diagnosis of MINOCA was associated with an increased risk of major adverse cardiovascular events at follow-up.

BACKGROUND
The risk of complications, including death, is substantially increased in patients with pulmonary hypertension (PH) undergoing anaesthesia for surgical procedures, especially in those with pulmonary arterial hypertension (PAH) and chronic thromboembolic PH (CTEPH). Sedation also poses a risk to patients with PH. Physiological changes including tachycardia, hypotension, fluid shifts, and an increase in pulmonary vascular resistance (PH crisis) can precipitate acute right ventricular decompensation and death.
METHODS
A systematic literature review was performed of studies in patients with PH undergoing non-cardiac and non-obstetric surgery. The management of patients with PH requiring sedation for endoscopy was also reviewed. Using a framework of relevant clinical questions, we review the available evidence guiding operative risk, risk assessment, preoperative optimisation, and perioperative management, and identifying areas for future research.
RESULTS
Reported 30 day mortality after non-cardiac and non-obstetric surgery ranges between 2% and 18% in patients with PH undergoing elective procedures, and increases to 15-50% for emergency surgery, with complications and death usually relating to acute right ventricular failure. Risk factors for mortality include procedure-specific and patient-related factors, especially markers of PH severity (e.g. pulmonary haemodynamics, poor exercise performance, and right ventricular dysfunction). Most studies highlight the importance of individualised preoperative risk assessment and optimisation and advanced perioperative planning.
CONCLUSIONS
With an increasing number of patients requiring surgery in specialist and non-specialist PH centres, a systematic, evidence-based, multidisciplinary approach is required to minimise complications. Adequate risk stratification and a tailored-individualised perioperative plan is paramount.

Cardiovascular disease (CVD) remains the leading cause of mortality in women, yet many people perceive breast cancer to be the number one threat to women's health. CVD and breast cancer have several overlapping risk factors, such as obesity and smoking. Additionally, current breast cancer treatments can have a negative impact on cardiovascular health (eg, left ventricular dysfunction, accelerated CVD), and for women with pre-existing CVD, this might influence cancer treatment decisions by both the patient and the provider. Improvements in early detection and treatment of breast cancer have led to an increasing number of breast cancer survivors who are at risk of long-term cardiac complications from cancer treatments. For older women, CVD poses a greater mortality threat than breast cancer itself. This is the first scientific statement from the American Heart Association on CVD and breast cancer. This document will provide a comprehensive overview of the prevalence of these diseases, shared risk factors, the cardiotoxic effects of therapy, and the prevention and treatment of CVD in breast cancer patients.
