Introduction: Heart transplantation is associated with prolonged survival and improved quality of life in patients with advanced cardiac disease albeit with an increased risk of malignancies due to the use of immunosuppressant medications. Our study aimed to determine the types and trends of in patients’ hospitalization for malignancies among heart transplant patients. Methods: We queried the 2005 to 2014 National Inpatient Sample(NIS) database to identify all patients with a history of heart transplant (ICD-9 codes V412, 99683) who were hospitalized with a diagnosis of cancer. The main outcome was the trend in cancer admissions. Secondary outcome were inpatient mortality, total charge and length of stay. Cochran’s and Mantel-Haenszel test was used to assess trends of cancer admissions. Adjusted OR were used to compare the incidence of death between the two groups. Results: A total of 36543(weighted national estimate of 177,604) patients were admitted with a history of heart transplantation over the study period, out of which 2347(6.4%) had a diagnosis of a malignancy. Cancer patients were older (Mean age 66±12 Vs. 61.1±18 P-Value <0.001) and were more likely to be male. There was an increasing trend in the rate of cancer admissions over the study period from 60 per 1000 patients in 2005 to 70 per 1000patients in 2014(P-Vale <0.0001). Overall the most prevalent cancer was Non-Hodgkin’s 20.9% followed by lung Cancer 19.1%. ninety-seven patients(4.1%) had a 2 or more cancers. Patients with a diagnosis of cancer were more likely to die while inpatients as compared those without a diagnosis of cancer (6.6% vs. 3.1%, adjusted OR 2.42 95%CI 1.53-3.38 P-value <0.001). Lastly, patients with cancer had an increased total median coast and a longer length of stay(Total charge(39735 vs, 32,035, P value =<0.001 and 5 vs. 4. P-value <0.001). Conclusion: Development of cancer among patients with a history of transplant adds significant morbidity and mortality. Further studies are needed to determine effective ways to reduce morbidity in this patient cohort.

Venous thromboembolism (VTE) and coronary artery disease are major health issues that cause substantial morbidity and mortality. New data have emerged suggesting that these two conditions could have a close relationship. Thus, we sought to determine the trends in annual rate of VTE occurrence in patients with ST-segment elevation myocardial infarction (STEMI) and measure its impact on in-hospital mortality, bleeding complications, and cost and length of hospitalization. We queried the 2003–2013 Nationwide Inpatient Sample databases to identify adults with primary diagnosis of STEMI. VTE events were then allocated. Inpatient outcomes of patients with VTE were compared to those without VTE. Out of 2,495,757 hospitalizations for STEMI, VTE was diagnosed in 25,149 (1%) hospitalizations. Patients who experienced VTE were older (mean age: 67.5 vs 64.8, p < 0.01) and had a higher proportion of black patients (10.1% vs 7.7%, p < 0.001) and females (40.1% vs 35%, p < 0.001) compared to patients without VTE. There was an increasing trend in the rate of VTE during the study period (2003: 0.8% vs 2013: 1.0%, p < 0.001). Patients with VTE had a prolonged hospitalization (median: 9 vs 3 days, p < 0.001), increased cost, higher risk of gastrointestinal bleeding (OR: 2.13, p < 0.001), intracranial hemorrhage (OR: 2.14, p < 0.001), blood transfusions (OR: 1.94, p < 0.001), and mortality (OR: 1.39, p < 0.001). The rate of VTE occurrence in patients with STEMI in our study was 10 per 1000 admissions. VTE was associated with more bleeding complications, longer hospital stays, higher costs, and mortality. These findings suggest that a more aggressive approach for VTE prophylaxis may be warranted in this population.
