Association of Potentially Inappropriate Medications With All-Cause Mortality in the Elderly Acute Decompensated Heart Failure Patients: Importance of Nonsteroidal Anti-Inflammatory Drug Prescription.

BACKGROUND: Acute decompensated heart failure (ADHF) is the most common cause of readmissions in the hospital. ADHF patients are associated with polypharmacy. It is a common problem among elderly patients due to frequently occurring multiple morbidities and is associated with the use of potentially inappropriate medications (PIMs). The aim of this study was to examine the association between PIMs and all-cause mortality in elderly ADHF patients. METHODS: This retrospective study included ADHF patients who were admitted to the Showa University Fujigaoka Hospital between January 2015 and August 2016. We investigated the proportion of patients taking at least one PIM at admission and the characteristics of patients at admission. PIMs were defined based on the Screening Tool of Older People's potentially inappropriate Prescriptions (STOPP). Multiple Cox regression analysis was performed to examine the association between PIM use and all-cause mortality. RESULTS: A total of 193 elderly patients (median age 81 years, interquartile range (IQR) 65 - 99 years) were included in the study. All-cause death occurred in 30 patients. The median number of medications at admission was 7 (IQR 0 - 18). The number of medications (greater than or equal to six) at admission was associated with mortality. Multivariate Cox regression analysis revealed that systolic blood pressure (SBP) < 100 mm Hg at admission, chronic obstructive pulmonary disease (COPD), and use of non-steroidal anti-inflammatory drugs (NSAIDs) at admission were independent predictors for all-cause mortality. CONCLUSIONS: The medical staff should attempt to stop unnecessary medications that are prone to be inappropriate prescribing. In particular, prescription of NSAIDs should be carefully assessed and monitored.

Prognostic Value of Left Atrial Size and Functional Indices Measured by 3-Dimensional Speckle-Tracking Analysis.

BACKGROUND: The prognostic value of indices for left atrial volumes (LAV) and reservoir function measured by 3D speckle-tracking analysis (3DSTA) has not been determined. Methods and Results: LA maximal and minimal volume indices (LAVImax, LAVImin), and LA emptying fraction (LAEmpF) were measured via 2D echocardiography (2DE) and 3DSTA in 514 patients (62% male, mean age: 66±15 years) with various cardiovascular diseases. Two cutoff values using normal±2SD (cutoff criterion 1) and receiver-operating characteristic analysis (cutoff criterion 2) were evaluated. During a mean follow-up of 720±383 days, MACE (cardiac death, nonfatal myocardial infarction, stroke and admission for heart failure) occurred in 98 patients. Kaplan-Meier survival analysis showed both cutoff criteria measured by 2DE and 3DSTA had significant predictive power for MACE (P<0.001). For cutoff criterion 1, 3DSTA measurements yielded higher hazard ratios than 2DE by Cox proportional hazard model. Cutoff criterion 2 using 3DSTA had higher average treatment effect values than 2DE by matching propensity scores on the outcome. Further, a regression model that included clinical variables, left ventricular ejection fraction and cutoff criterion 2 using 3DSTA-derived LAEmpF had significantly higher prognostic power than 2DE. CONCLUSIONS: LA indices measured by 3DSTA had greater prognostic power for future MACE than 2DE. In particular, 3DSTA-derived LAEmpF has the potential to be a valuable prognostic tool in clinical settings.

Long-Term Effects of Enzyme Replacement Therapy for Anderson-Fabry Disease.

Anderson-Fabry disease is a rare X-linked lysosomal storage disease caused by α-galactosidase A (α-GalA) gene variants and characterized by a large genotypic and phenotypic spectrum. Enzyme replacement therapy (ERT) using recombinant α-GalA has been approved for > 10 years as a specific therapy for the disease. However, the long-term clinical efficacy for cardiac manifestations has been equivocal because it depends on several factors such as genotype, sex, age, and disease severity at the initiation of ERT. We report the differences in the clinical effects of ERT continued for > 10 years in three patients with the same genotype. Left ventricular hypertrophy and myocardial dysfunction progressed in the heterozygote proband even under ERT, although disease progression was prevented in two sons of Case 1.
