ObjectivesThe primary objective was to examine the association between hyperlipidaemia (HLP) and 5-year survival after incident acute myocardial infarction (AMI). The secondary objectives were to assess the effect of HLP on survival to discharge across patient subgroups, and the impact of statin prescription, intensity and long-term statin adherence on 5-year survival.MethodsRetrospective cohort study of 7071 patients hospitalised for AMI at Mayo Clinic from 2001 through 2011. Of these, 2091 patients with HLP (age (mean±SD) 69.7±13.5) were propensity score matched to 2091 patients without HLP (age 70.6±14.2).ResultsIn matched patients, HLP was associated with higher rate of survival to discharge than no HLP (95% vs 91%; log-rank <0.0001). At year 5, the adjusted HR for all-cause mortality in patients with HLP versus no HLP was 0.66 (95% CI 0.58–0.74), and patients with prescription statin versus no statin was 0.24 (95% CI 0.21 to 0.28). The mean survival was 0.35 year greater in patients with HLP than in those with no HLP (95% CI 0.25 to 0.46). Patients with HLP gained on an average 0.17 life year and those treated with statin 0.67 life year at 5 years after AMI. The benefit of concurrent HLP was consistent across study subgroups.ConclusionsIn patients with AMI, concomitant HLP was associated with increased survival and a net gain in life years, independent of survival benefit from statin therapy. The results also reaffirm the role of statin prescription, intensity and adherence in reducing the mortality after incident AMI.

Background The etiology of febrile neutropenia in patients with hematological malignancy is identified in only 20–30% of cases. Sinus computed tomography (CT) is often used, regardless of symptoms, to rule out rhinocerebral source of infection. There are no clear guidelines on when to perform sinus CT in this population. In this study, we evaluated the role of sinus CT in febrile neutropenic patients. Methods We retrospectively reviewed medical records of all adults (age ≥18 years) with febrile neutropenia (T≥ 38.3ºC, ANC &lt; 0.5 x 109/L) and hematological malignancies who underwent sinus CT from January 2014 to May 2020. We present the preliminary analysis of the impact of sinus CT findings on the management of febrile neutropenia. Results 47 patients with a total of 56 episodes of febrile neutropenia met the inclusion criteria. The median age at presentation was 57 years (IQR: 42 - 68 years). The most common underlying malignancy was acute myeloid leukemia (51%), followed by myelodysplastic syndrome (19%). At presentation, 47% had refractory disease, 21% were newly diagnosed, 15% had relapsed, 15% were in complete remission, and 2% were in partial remission. Of the total 56 episodes, 29 (52%) had symptoms of rhinorrhea (20%), facial pain (14%), and sinus congestion (14%). The remaining 27 of 56 episodes (48%) had no sinus symptoms. Sinus CT was abnormal in 48 of 56 episodes (86%); the most common finding was mucosal thickening (47/48; 98%), followed by air-fluid levels (7/48; 14.5%), partial opacification (6/48; 12.5%), complete opacification (2/48; 4%), and bony invasion (2/48; 4%). The source of febrile neutropenia was attributed to the CT sinus findings in 9 cases (9/48; 29%), leading to a change in therapeutic management. All 9 patients were symptomatic, with evidence of necrosis in 22% (2/9) and purulence in 22% (2/9) on nasal endoscopy. Table 1 Conclusion Mucosal thickening is a frequent and non-specific imaging finding, particularly in patients without sinus symptoms. Sinus CT findings in patients with febrile neutropenia without sinus symptoms had no impact on clinical management. Consequently, sinus CT may be reserved for patients presenting with sinus symptoms.
