Contemporary cardiac intensive care units (CICUs) have an increasing prevalence of noncardiovascular comorbidities and multisystem organ dysfunction. However, little guidance exists to support the development of best-practice principles specific to the CICU. This scientific statement evaluates strategies to avoid the potentially preventable complications encountered within contemporary CICUs, focusing on those that are most applicable to the CICU environment. This scientific statement reviews evidence-based practices derived in non-CICU populations, assesses their relevance to CICU practice, and highlights key knowledge gaps warranting further investigation to attenuate patient risk.

The medical complexity and critical care needs of patients admitted to cardiac ICUs are increasing, and prospective studies examining the underlying cardiac and noncardiac diagnoses, the management strategies, and the prognosis of cardiac ICU patients with respiratory failure are needed.

BACKGROUND:Myocardial infarction (MI) complicated by cardiogenic shock (CS) is associated with high mortality. Early coronary revascularization improves survival, but the optimal mode of revascularization remains uncertain. We sought to characterize practice patterns and outcomes of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with MI complicated by CS. METHODS:Patients hospitalized for MI with CS between 2002 and 2014 were identified from the United States National Inpatient Sample. Trends in management were evaluated over time. Propensity score matching was performed to identify cohorts with similar baseline characteristics and MI presentations who underwent PCI and CABG. The primary outcome was in-hospital all-cause mortality. RESULTS:A total of 386,811 hospitalizations for MI with CS were identified; 67% were STEMI. Overall, 62.4% of patients underwent revascularization, with PCI in 44.9%, CABG in 14.1%, and a hybrid approach in 3.4%. Coronary revascularization for MI and CS increased over time, from 51.5% in 2002 to 67.4% in 2014 (P for trend < .001). Patients who underwent CABG were more likely to have diabetes mellitus (35.5% vs. 29.2%, P < .001) and less likely to present with STEMI (48.7% vs. 80.9%, P < .001) than those who underwent PCI. CABG (without PCI) was associated with lower mortality than PCI (without CABG) overall (18.9% vs. 29.0%, P < .001) and in a propensity-matched subgroup of 19,882 patients (19.0% vs. 27.0%, P < .001). CONCLUSIONS:CABG was associated with lower in-hospital mortality than PCI among patients with MI complicated by CS. Due to the likelihood of residual confounding, a randomized trial of PCI versus CABG in patients with MI, CS, and multi-vessel coronary disease is warranted.

To explore demographics, comorbidities, transfers, and mortality in critically ill patients with confirmed severe acute respiratory syndrome coronavirus 2.

The COVID-19 pandemic has presented a major unanticipated stress on our workforce, organizational structure, systems of care, and critical resource supply. In order to ensure provider safety, maximize efficiency, and optimize patient outcomes, health systems need to be agile. Critical care cardiologists may be uniquely positioned to treat the numerous respiratory and cardiovascular complications of the SARS-CoV-2 virus and support clinicians without critical care training who may be suddenly asked to care for critically ill patients. This manuscript draws upon the experiences of colleagues from heavily impacted regions of the United States and Europe as well as lessons learned from military mass casualty medicine. We offer pragmatic suggestions on how to implement scalable models for critical care delivery, cultivate educational tools for team training, and embrace technologies such as telemedicine to enable effective collaboration despite social distancing imperatives.
