Characteristics and Outcomes of Adults With Congenital Heart Disease in the Cardiac Intensive Care Unit.

Background: Little is known regarding the characteristics, treatment patterns, and outcomes in patients with adult congenital heart disease (ACHD) admitted to cardiac intensive care units (CICUs). Objectives: The authors sought to better define the contemporary epidemiology, treatment patterns, and outcomes of ACHD admissions in the CICU. Methods: The Critical Care Cardiology Trials Network is a multicenter network of CICUs in North America. Participating centers contributed prospective data from consecutive admissions during 2-month annual snapshots from 2017 to 2022. We analyzed characteristics and outcomes of admissions with ACHD compared with those without ACHD. Multivariable logistic regression was used to assess mortality in ACHD vs non-ACHD admissions. Results: Of 23,299 CICU admissions across 42 sites, there were 441 (1.9%) ACHD admissions. Shunt lesions were most common (46.1%), followed by right-sided lesions (29.5%) and complex lesions (28.7%). ACHD admissions were younger (median age 46 vs 67 years) than non-ACHD admissions. ACHD admissions were more commonly for heart failure (21.3% vs 15.7%, P < 0.001), general medical problems (15.6% vs 6.0%, P < 0.001), and atrial arrhythmias (8.6% vs 4.9%, P < 0.001). ACHD admissions had a higher median presenting Sequential Organ Failure Assessment score (5.0 vs 3.0, P < 0.001). Total hospital stay was longer for ACHD admissions (8.2 vs 5.9 days, P < 0.01), though in-hospital mortality was not different (12.7% vs 13.6%; age- and sex-adjusted OR: 1.19 [95% CI: 0.89-1.59], P = 0.239). Conclusions: This study illustrates the unique aspects of the ACHD CICU admission. Further investigation into the best approach to manage specific ACHD-related CICU admissions, such as cardiogenic shock and acute respiratory failure, is warranted.

Characteristics, therapies, and outcomes of In-Hospital vs Out-of-Hospital cardiac arrest in patients presenting to cardiac intensive care units: From the critical care Cardiology trials network (CCCTN).

BACKGROUND: Cardiac arrest (CA) is a common reason for admission to the cardiac intensive care unit (CICU), though the relative burden of morbidity, mortality, and resource use between admissions with in-hospital (IH) and out-of-hospital (OH) CA is unknown. We compared characteristics, care patterns, and outcomes of admissions to contemporary CICUs after IHCA or OHCA. METHODS: The Critical Care Cardiology Trials Network is a multicenter network of tertiary CICUs in the US and Canada. Participating centers contributed data from consecutive admissions during 2-month annual snapshots from 2017 to 2021. We analyzed characteristics and outcomes of admissions by IHCA vs OHCA. RESULTS: We analyzed 2,075 admissions across 29 centers (50.3% IHCA, 49.7% OHCA). Admissions with IHCA were older (median 66 vs 62 years), more commonly had coronary disease (38.3% vs 29.7%), atrial fibrillation (26.7% vs 15.6%), and heart failure (36.3% vs 22.1%), and were less commonly comatose on CICU arrival (34.2% vs 71.7%), p < 0.001 for all. IHCA admissions had lower lactate (median 4.3 vs 5.9) but greater utilization of invasive hemodynamics (34.3% vs 23.6%), mechanical circulatory support (28.4% vs 16.8%), and renal replacement therapy (15.5% vs 9.4%); p < 0.001 for all. Comatose IHCA patients underwent targeted temperature management less frequently than OHCA patients (63.3% vs 84.9%, p < 0.001). IHCA admissions had lower unadjusted CICU (30.8% vs 39.0%, p < 0.001) and in-hospital mortality (36.1% vs 44.1%, p < 0.001). CONCLUSION: Despite a greater burden of comorbidities, CICU admissions after IHCA have lower lactate, greater invasive therapy utilization, and lower crude mortality than admissions after OHCA.

Health Professional Training and Capacity Strengthening Through International Academic Partnerships: The First Five Years of the Human Resources for Health Program in Rwanda.

BACKGROUND: The Rwanda Human Resources for Health Program (HRH Program) is a 7-year (2012-2019) health professional training initiative led by the Government of Rwanda with the goals of training a large, diverse, and competent health workforce and strengthening the capacity of academic institutions in Rwanda. METHODS: The data for this organizational case study was collected through official reports from the Rwanda Ministry of Health (MoH) and 22 participating US academic institutions, databases from the MoH and the College of Medicine and Health Sciences (CMHS) in Rwanda, and surveys completed by the co-authors. RESULTS: In the first 5 years of the HRH Program, a consortium of US academic institutions has deployed an average of 99 visiting faculty per year to support 22 training programs, which are on track to graduate almost 4600 students by 2019. The HRH Program has also built capacity within the CMHS by promoting the recruitment of Rwandan faculty and the establishment of additional partnerships and collaborations with the US academic institutions. CONCLUSION: The milestones achieved by the HRH Program have been substantial although some challenges persist. These challenges include adequately supporting the visiting faculty; pairing them with Rwandan faculty (twinning); ensuring strong communication and coordination among stakeholders; addressing mismatches in priorities between donors and implementers; the execution of a sustainability strategy; and the decision by one of the donors not to renew funding beyond March 2017. Over the next 2 academic years, it is critical for the sustainability of the 22 training programs supported by the HRH Program that the health-related Schools at the CMHS significantly scale up recruitment of new Rwandan faculty. The HRH Program can serve as a model for other training initiatives implemented in countries affected by a severe shortage of health professionals.

Causes and Predictors of Death in Patients With Coronary Heart Disease (from the Heart and Soul Study).

Although the prevalence of coronary heart disease (CHD) in the United States has increased during the past 25 years, cardiovascular mortality has decreased due to advances in CHD therapy and prevention. We sought to determine the proportion of patients with CHD who die from cardiovascular versus noncardiovascular causes and the causes and predictors of death, in a cohort of patients with CHD. The Heart and Soul Study enrolled 1,024 participants with stable CHD from 2000 to 2002 and followed them for 10 years. Causes of mortality were assigned based on detailed review of medical records, death certificates, and coroner reports by blinded adjudicators. During 7,680 person-years of follow-up, 401 participants died. Of these deaths, 42.4% were cardiovascular and 54.4% were noncardiovascular. Myocardial infarction, stroke, and sudden death accounted for 72% of cardiovascular deaths. Cancer, pneumonia, and sepsis accounted for 67% of noncardiovascular deaths. Independent predictors of cardiac mortality were older age, inducible ischemia on stress echocardiography, higher heart rate at rest, smoking, lower hemoglobin, and higher N-terminal pro-brain natriuretic peptide (all p values <0.05); independent predictors of noncardiac mortality included older age, inducible ischemia, higher heart rate, lower exercise capacity, and nonuse of statins (all p values <0.05). In conclusion, mortality in this cohort was more frequently due to noncardiovascular causes, and predictors of noncardiovascular mortality included factors traditionally associated with cardiovascular mortality.
