Maternal and Pregnancy Outcomes Following Heart Transplantation in the United States.

BACKGROUND: Improved survival following heart transplantation (HT) has led to more recipients contemplating pregnancy, but data on outcomes are limited. OBJECTIVES: The authors used a national data set to investigate and describe outcomes of pregnancies and deliveries in the United States in HT recipients. METHODS: Diagnosis and procedure codes from the 2010-2020 Nationwide Readmissions Database identified delivery hospitalizations, history of HT, comorbid conditions, and outcomes. The authors compared rates of severe maternal morbidity (SMM), nontransfusion SMM, cardiovascular SMM (cSMM), and preterm birth from delivery hospitalization between HT recipients and no-HT recipients. The authors evaluated readmission to 330 days postpartum. Logistic and proportional hazard regressions were performed, adjusting for age, socioeconomic and facility characteristics, and clinical comorbidities. RESULTS: Among 19,399,521 deliveries, 105 were HT recipients. Compared with no-HT, HT recipients were at higher risk for all SMM (24.8% vs 1.7%), nontransfusion SMM (20.8% vs 0.7%), cSMM (7.3% vs 0.12%), and preterm birth (43.3% vs 8.2%), all P < 0.001. In adjusted analyses, HT recipients had 16-fold greater odds of SMM, 28-fold greater odds of nontransfusion SMM, 38-fold greater odds of cSMM, and 7-fold greater odds of preterm birth. HT recipients had higher morbidity rates during delivery hospitalization and higher readmission rates within 1 year following delivery (26.9% vs 3.8%; adjusted HR: 6.03 [95% CI: 3.73-9.75]). CONCLUSIONS: Delivery with history of HT is associated with significantly increased rates of SMM, preterm birth, and hospital readmission. These results provide data regarding pregnancy outcomes for use when counseling patients with HT history who are considering pregnancy or who are pregnant.

Disparities in Loss to Follow-Up Among Adults With Congenital Heart Disease in North Carolina.

BACKGROUND: The AHA/ACC Adult Congenital Heart Disease guidelines recommend that most adults with congenital heart disease (CHD) follow-up with CHD cardiologists every 1 to 2 years because longer gaps in care are associated with adverse outcomes. This study aimed to determine the proportion of patients in North Carolina who did not have recommended follow-up and to explore predictors of loss to follow-up. METHODS: Patients ages ≥18 years with a healthcare encounter from 2008 to 2013 in a statewide North Carolina database with an ICD-9 code for CHD were assessed. The proportion with cardiology follow-up within 24 months following index encounter was assessed with Kaplan-Meier estimates. Cox regression was utilized to identify demographic factors associated with differences in follow-up. RESULTS: 2822 patients were identified. Median age was 35 years; 55% were female. 70% were white, 22% black, and 3% Hispanic; 36% had severe CHD. The proportion with 2-year cardiology follow-up was 61%. Those with severe CHD were more likely to have timely follow-up than those with less severe CHD (72% vs 55%, P < .01). Black patients had a lower likelihood of follow-up than white patients (56% vs 64%, P = .01). Multivariable Cox regression identified younger age, non-severe CHD, and non-white race as risk factors for a lower likelihood of follow-up by 2 years. CONCLUSION: 39% of adults with CHD in North Carolina are not meeting AHA/ACC recommendations for follow-up. Younger and minority patients and those with non-severe CHD were particularly vulnerable to inadequate follow-up; targeted efforts to retain these patients in care may be helpful.

Early diuretic strategies and the association with In-hospital and Post-discharge outcomes in acute heart failure.

BACKGROUND: Decongestion is a primary goal during hospitalizations for decompensated heart failure (HF). However, data surrounding the preferred route and strategy of diuretic administration are limited with varying results in prior studies. METHODS: This is a retrospective analysis using patients from ASCEND-HF with a stable diuretic strategy in the first 24 hours following randomization. Patients were divided into three groups: intravenous (IV) continuous, IV bolus and oral strategy. Baseline characteristics, in-hospital outcomes, 30-day composite cardiovascular mortality or HF rehospitalization and 180-day all-cause mortality were compared across groups. Inverse propensity weighted modeling was used for adjustment. RESULTS: Among 5,738 patients with a stable diuretic regimen in the first 24 hours (80% of overall ASCEND trial), 3,944 (68.7%) patients received IV intermittent bolus administration of diuretics, 799 (13.9%) patients received IV continuous therapy and 995 (17.3%) patients with oral administration. Patients in the IV continuous group had a higher baseline creatinine (IV continuous 1.4 [1.1-1.7]; intermittent bolus 1.2 [1.0-1.6]; oral 1.2 [1.0-1.4] mg/dL; P <0.001) and high NTproBNP (IV continuous 5,216 [2,599-11,603]; intermittent bolus 4,944 [2,339-9,970]; oral 3,344 [1,570-7,077] pg/mL; P <0.001). There was no difference between IV continuous and intermittent bolus group in weight change, total urine output and change in renal function till 10 days/discharge (adjusted P >0.05 for all). There was no difference in 30 day mortality and HF readmission (adjusted OR 1.08 [95%CI: 0.74, 1.57]; P = 0.701) and 180 days mortality (adjusted OR 1.04 [95%CI: 0.75, 1.43]; P = 0.832). CONCLUSION: In a large cohort of patients with decompensated HF, there were no significant differences in diuretic-related in-hospital, or post-discharge outcomes between IV continuous and intermittent bolus administration. Tailoring appropriate diuretic strategy to different states of acute HF and congestion phenotypes needs to be further investigated.
