The worldwide pandemic caused by the novel acute respiratory syndrome coronavirus 2 has resulted in a new and lethal disease termed coronavirus disease 2019 (COVID-19). Although there is an association between cardiovascular disease and COVID-19, the majority of patients who need cardiovascular care for the management of ischemic heart disease may not be infected with this novel coronavirus. The objective of this document is to provide recommendations for a systematic approach for the care of patients with an acute myocardial infarction (AMI) during the COVID-19 pandemic. There is a recognition of two major challenges in providing recommendations for AMI care in the COVID-19 era. Cardiovascular manifestations of COVID-19 are complex with patients presenting with AMI, myocarditis simulating an ST-elevation myocardial infarction (STEMI) presentation, stress cardiomyopathy, non-ischemic cardiomyopathy, coronary spasm, or nonspecific myocardial injury, and the prevalence of COVID-19 disease in the US population remains unknown with risk of asymptomatic spread. This document addresses the care of these patients focusing on (a) varied clinical presentations; (b) appropriate personal protection equipment (PPE) for health care workers; (c) the roles of the emergency department, emergency medical system, and the cardiac catheterization laboratory (CCL); and (4) regional STEMI systems of care. During the COVID-19 pandemic, primary percutaneous coronary intervention (PCI) remains the standard of care for STEMI patients at PCI-capable hospitals when it can be provided in a timely manner, with an expert team outfitted with PPE in a dedicated CCL room. A fibrinolysis-based strategy may be entertained at non-PCI-capable referral hospitals or in specific situations where primary PCI cannot be executed or is not deemed the best option.

A systematic review of randomized trials comparing double versus triple antithrombotic therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention

Sullivan, Alexander E; Nanna, Michael G; Rao, Sunil V; Cantrell, Sarah; Gibson, C Michael; Verheugt, Freek W A; Peterson, Eric D; Lopes, Renato D; Alexander, John H; Granger, Christopher B; Yee, Megan K; Kong, David F
BACKGROUND:Prior randomized controlled trials (RCT) evaluating the optimal antithrombotic therapies for patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) have not been powered to evaluate ischemic outcomes. We compared double therapy with oral anticoagulation (OAC) and a P2Y12 inhibitor to triple therapy with an OAC + dual antiplatelet therapy in patients with AF requiring PCI. METHODS:Using PRISMA guidelines, we searched for RCTs including patients with AF as an indication for OAC and undergoing PCI or medical management of acute coronary syndrome. The results were pooled using fixed-effects and random-effects models to estimate the overall effect of double therapy versus triple therapy on ischemic and bleeding outcomes. RESULTS:= 64%), as were intracranial hemorrhages (19/5470 vs. 30/4710; fixed effect model OR 0.54, 95% CI 0.31-0.96). CONCLUSIONS:Double therapy in patients with AF requiring OAC following PCI or Acute coronary syndrome has a significantly better safety profile than triple therapy but may be associated with a modest increased risk of stent thrombosis.

The State of Percutaneous Intervention in Stable Coronary Artery Disease

Drescher, Caitlin; Rao, Sunil V
PURPOSE OF REVIEW:This review examines trials of percutaneous coronary intervention (PCI) compared with optimal medical therapy (OMT) in order to inform clinical decision-making regarding the role of PCI in stable ischemic heart disease (SIHD). RECENT FINDINGS:Several large, randomized, controlled trials published in recent years suggest that OMT should be the initial treatment strategy for symptomatic SIHD, but there is a role for PCI in patients who continue to be symptomatic despite OMT. Additionally, using fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) techniques may help to identify physiologically significant lesions and may be useful in maximizing the benefit from PCI in SIHD. Recent trials demonstrate PCI for the treatment of symptomatic SIHD does not reduce mortality compared with OMT but effectively relieves anginal symptoms. However, OMT continues to be the first-line therapy for SIHD but is significantly underutilized.

Performance of Hospitals When Assessing Disease-Based Mortality Compared With Procedural Mortality for Patients With Acute Myocardial Infarction

Nathan, Ashwin S; Xiang, Qun; Wojdyla, Daniel; Khatana, Sameed Ahmed M; Dayoub, Elias J; Wadhera, Rishi K; Bhatt, Deepak L; Kolansky, Daniel M; Kirtane, Ajay J; Rao, Sunil V; Yeh, Robert W; Groeneveld, Peter W; Wang, Tracy Y; Giri, Jay
Importance:Quality of percutaneous coronary intervention (PCI) is commonly assessed by risk-adjusted mortality. However, this metric may result in procedural risk aversion, especially for high-risk patients. Objective:To determine correlation and reclassification between hospital-level disease-specific mortality and PCI procedural mortality among patients with acute myocardial infarction (AMI). Design, Setting, and Participants:This hospital-level observational cross-sectional multicenter analysis included hospitals participating in the Chest Pain-MI Registry, which enrolled consecutive adult patients admitted with a diagnosis of type I non-ST-segment elevation myocardial infarction (NSTEMI) or ST-segment elevation myocardial infarction (STEMI), and hospitals in the CathPCI Registry, which enrolled consecutive adult patients treated with PCI with an indication of NSTEMI or STEMI, between April 1, 2011, and December 31, 2017. Exposures:Inclusion into the National Cardiovascular Data Registry Chest Pain-MI and CathPCI registries. Main Outcomes and Measures:For each hospital in each registry, a disease-based excess mortality ratio (EMR-D) for AMI was calculated, which represents a risk-adjusted observed to expected rate of mortality for AMI as a disease using the Chest Pain-MI Registry, and a procedure-based excess mortality ratio (EMR-P) for PCI was calculated using the CathPCI Registry. Results:A subset of 625 sites participated in both registries, with a final count of 776 890 patients from the Chest Pain-MI Registry (509 576 men [65.6%]; 620 981 white [80.0%]; and median age, 64 years [interquartile range, 55-74 years]) and 853 386 patients from the CathPCI Registry (582 701 men [68.3%]; 691 236 white [81.0%]; and median age, 63 years [interquartile range, 54-73 years]). Among the 625 linked hospitals, the Spearman rank correlation coefficient between EMR-D and EMR-P produced a ρ of 0.53 (95% CI, 0.47-0.58), suggesting moderate correlation. Among the highest-performing tertile for disease-based risk-adjusted mortality, 90 of 208 sites (43.3%) were classified into a lower category for procedural risk-adjusted mortality. Among the lowest-performing tertile for disease-based risk-adjusted mortality, 92 of 208 sites (44.2%) were classified into a higher category for procedural risk-adjusted mortality. Bland-Altman plots for the overall linked cohort demonstrate a mean difference between EMR-P and EMR-D of 0.49% (95% CI, -1.61% to 2.58%; P < .001), with procedural mortality higher than disease-based mortality. However, among patients with AMI complicated by cardiogenic shock or cardiac arrest, the mean difference between EMR-P and EMR-D was -0.64% (95% CI, -4.41% to 3.12%; P < .001), with procedural mortality lower than disease-based mortality. Conclusions and Relevance:This study suggests that, for hospitals treating patients with AMI, there is only a moderate correlation between procedural outcomes and disease-based outcomes. Nearly half of hospitals in the highest tertile of performance for PCI performance were reclassified into a lower performance tertile when judged by disease-based metrics. Higher rates of mortality were observed when using disease-based metrics compared with procedural metrics when assessing patients with cardiogenic shock and/or cardiac arrest, signifying what appears to be potential risk avoidance among this highest-risk subset of patients.

A reduced transferrin saturation is independently associated with excess morbidity and mortality in older adults with heart failure and incident anemia

Ambrosy, Andrew P; Fitzpatrick, Jesse K; Tabada, Grace H; Gurwitz, Jerry H; Artz, Andrew; Schrier, Stanley L; Rao, Sunil V; Reynolds, Kristi; Smith, David H; Peterson, Pamela N; Fortmann, Stephen P; Sung, Sue Hee; Cohen, Harvey Jay; Go, Alan S
BACKGROUND:Low transferrin saturation (TSAT) or reduced serum ferritin level are suggestive of iron deficiency but the relationship between iron parameters and outcomes has not been systematically evaluated in older adults with heart failure (HF) and anemia. METHODS:We identified a multicenter cohort of adults age ≥ 65 years with HF and incident anemia (hemoglobin <13 g/dL [men] or < 12 g/dL [women]) between 2005 and 2012. Patients were included if ferritin (ng/mL) and TSAT (%) were evaluated within 90 days of incident anemia. HF hospitalizations and all-cause death were ascertained from electronic health records. RESULTS:Among 4103 older adults with HF and incident anemia, 47% had TSAT <20% and the median (IQR) ferritin was 126 (53, 256) ng/mL. In multivariable analyses, compared with TSAT ≥20%, patients with TSAT <20% were at increased risk of HF hospitalization for serum ferritin <100 ng/mL (adjusted HR [aHR] 1.40, 95% CI:1.16-1.70) and 100-300 ng/mL (aHR 1.24, 95% CI:1.01-1.52) but not for a ferritin >300 ng/mL (aHR 0.89, 95% CI 0.65-1.23). In addition, TSAT <20% was independently associated with an increased risk of all-cause death regardless of serum ferritin level (<100 ng/mL: aHR 1.42, 95% CI:1.20-1.68; 100-300 ng/mL: aHR 1.18, 95% CI:1.00-1.38; >300 ng/mL: aHR 1.33, 95% CI:1.06-1.69). CONCLUSIONS:Among older adults with HF and incident anemia who had iron studies tested, nearly half had a TSAT <20%, which was independently associated with higher rates of morbidity and death.

Percutaneous coronary intervention or coronary artery bypass graft surgery for left main coronary artery disease: A meta-analysis of randomized trials [Letter]

Kuno, Toshiki; Ueyama, Hiroki; Rao, Sunil V; Cohen, Mauricio G; Tamis-Holland, Jacqueline E; Thompson, Craig; Takagi, Hisato; Bangalore, Sripal
We aimed to investigate long-term (≥5 years) outcomes of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD) using a meta-analysis from updated published randomized trials. Our data showed that the risk of all-cause death as well as cardiovascular death, myocardial infarction, and stroke was similar between PCI and CABG, whereas PCI had significantly higher rates of repeat revascularization compared to CABG. Decisions for PCI versus CABG for LMCAD should be based on weighing the upfront morbidity and mortality risk of CABG with late risk of repeat revascularization with PCI and taking into consideration patient preference.
