Abstract

Aims: We aimed to elucidate the association between malnutrition and the occurrence of bleeding events in patients with heart failure. Methods and results: We evaluated the nutritional status of patients with heart failure [n = 2044, median (inter‐quartile range) age 69.0 (59.0–78.0) years, 1209 (59.1%) males] using the Geriatric Nutritional Risk Index (GNRI). The primary endpoint was a composite of bleeding events such as haemorrhagic stroke or gastrointestinal bleeding. According to the survival classification and regression tree analysis, the accurate cut‐off point of GNRI for predicting the primary endpoint was 106.2. We divided the patients into two groups based on GNRI levels: high GNRI group (GNRI ≥ 106.2, n = 606, 29.6%) and low GNRI group (GNRI < 106.2, n = 1438, 70.4%). We compared the patients' characteristics and prognosis between the two groups. The low GNRI group was older [72.0 (63.0–79.0) vs. 63.0 (53.0–73.0) years, P < 0.001] and had a lower prevalence of male sex (56.9% vs. 64.5%, P = 0.001). There were no differences in the use of antiplatelet agents and anticoagulants between the two groups. Levels of B‐type natriuretic peptide were higher [321.1 (123.3–667.4) vs. 111.6 (42.6–235.4) pg/mL, P < 0.001] and levels of haemoglobin were lower [12.4 (10.8–13.7) vs. 14.2 (12.9–15.4) g/dL, P < 0.001] in the low GNRI group. The Kaplan–Meier analysis demonstrated that bleeding event rates were higher in the low GNRI group (log‐rank P < 0.001). The multivariable Cox proportional hazard analysis revealed that low GNRI (hazard ratio 1.952, 95% confidence interval 1.002–3.805, P = 0.049) was associated with bleeding events. Conclusions: Heart failure patients with poor nutritional status, determined by GNRI under 106.2, experienced high bleeding event rates. Comprehensive management is required to avoid bleeding event in those populations. [ABSTRACT FROM AUTHOR]

Abstract

Cardiac angiosarcoma is a rare malignant tumor with a poor prognosis, characterized by the high uptake of 18F-fluorodeoxyglucose (FDG). This case report presents two cases of cardiac angiosarcoma with a marked difference in FDG uptake and prognosis.Case Summary:Case 1: A 40-year-old male presented with syncope. Ultrasound echocardiography demonstrated a cardiac tumor with a high uptake of 18F-FDG (maximum standardized uptake value=9.2). The patient underwent heart catheterization and tumor biopsy. The pathological result was high-grade angiosarcoma, and the MIB-1(Ki-67) proliferation index was approximately 20%. Systemic chemotherapy was administered; however, the patient died 2 years and 5 months after disease onset.Case 2: A 65-year-old female had a right atrial tumor incidentally diagnosed during routine ultrasound echocardiography. The tumor exhibited a low uptake of 18F-FDG (maximum standardized uptake value=1.8). Open heart surgery was performed, and the tumor was completely resected. Histological analysis revealed low-grade angiosarcoma, and the MIB-1(Ki-67) proliferation index was less than 5%. The patient was followed-up and had not relapsed 2 years after surgery.Conclusion: 18F-FDG uptake may reflect pathological tumor grade and prognosis in cardiac angiosarcoma.

Abstract

Background: To compare phase analysis with positron emission tomography (PA) and magnetic resonance feature tracking derived myocardial strain (FT) for left ventricular (LV) mechanical dyssynchrony using PETMR system in patients with ischemic heart disease. Methods and results: Patients who underwent rest-pharmacological stress 13N ammonia PETMR were enrolled. Histogram bandwidth (BW) and phase standard deviation (PSD) were compared to global longitudinal, long axis radial, short axis circumferential, and radial strain (GLS, GRS, SA Circ, and SA Rad) obtained from FT. LV dyssynchrony index (SDI) derived from PA and FT were compared. BW and PSD showed significant correlations with FT (a Pearson's coefficient r = 0.64, P <.0001, and r = 0.51, P <.0001 for SA Circ; r = 0.67, P <.0001, and r = 0.74, P <.0001 for GLS; r = − 0.60, P <.0001, r = − 0.61, P <.0001 for SA Rad; r = − 0.62, P <.0001, and r = − 0.68, P <.0001 for GRS, respectively). Bland-Altman plots for SDI showed a preferable agreement (95% limit of agreement − 0.12 to 0.075, − 0.20 to 0.098, − 0.38 to 0.077, and − 0.37 to 0.032; bias 0.0068 ± 0.056, 0.026 ± 0.068, 0.11 ± 0.088, and 0.13 ± 0.079 for SA Circ, SA Rad, GLS, and GRS, respectively). Conclusion: In simultaneous acquisition using PETMR, comparison of PET phase analysis and MR strain showed a good correlation. [ABSTRACT FROM AUTHOR]
