Background: Current guidelines for the treatment of heart failure with reduced ejection fraction (HFrEF) are based on studies that have excluded or underrepresented older patients.

Objectives: To assess the value of guideline directed medical therapy (GDMT) in HFrEF patients 80 years of age and older.

Methods: A single-center retrospective study included patients hospitalized with a first and primary diagnosis of acute decompensated heart failure (ADHF) and ejection fraction (EF) of ≤ 40%. Patients 80 years of age and older were stratified into two groups: GDMT, defined as treatment at hospital discharge with at least two drugs of the following groups: beta-blockers, angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), or mineralocorticoid antagonists; and a personalized medicine group, which included patients who were treated with up to one of these drug groups. The primary outcomes were 90-day all-cause mortality, 90-day rehospitalization, and 3-years mortality.

Results: The study included 1152 patients with HFrEF. 254 (22%) patients who were at least 80 years old. Of the group, 123 were GDMT at discharge. When GDMT group was compared to the personalized medicine group, there were no statistically significant differences in terms 90-day mortality (17% vs. 13%, P = 0.169), 90-day readmission (51 % vs. 45.6%, P = 0.27), or 3-year mortality (64.5% vs. 63.3%, P = 0.915).

Conclusions: Adherence to guidelines in the older adult population may not have the same effect as in younger patients who were studied in the randomized clinical trials. Larger prospective studies are needed to further address this issue.

Background: Recurrent miscarriages are associated with a high prevalence of thrombophilia. Use of a calibrated automated thrombogram (CAT) can serve as a universal test for thrombophilia.

Objectives: To examine whether thrombin generation measured by CAT is elevated during the first trimester in women with unexplained recurrent miscarriages.

Methods: This study comprised 25 pregnant women with recurrent pregnancy loss referred for thrombophilia screening and treated with low-molecular-weight heparin (LMWH). Thrombin generation parameters were measured in women who had miscarriages or live births and who were diagnosed as positive or negative for thrombophilia.

Results: Of the pregnancies, 76% resulted in live birth and 24% ended in miscarriages. Among the women, 76% were positive for thrombophilia. Thrombin generation parameters between pregnancies that ended in miscarriage compared to live births were not significantly different, and CAT parameters failed to predict pregnancy outcome. Although the CAT parameters demonstrated a trend toward a hypercoagulable state in women with thrombophilia, there was no statistical significance (P > 0.05).

Conclusions: Women with unexplained pregnancy loss demonstrated similar thrombin generation in the first trimester, regardless of the pregnancy outcome. CAT parameters failed to predict pregnancy outcome in women with recurrent unexplained pregnancy loss. Our results should be interpreted with caution due to the small number of participants.
