Characteristics and Outcomes of Heart Failure Outpatients with Improvement in Ejection Fraction in Qatar.

Introduction: Heart failure with reduced ejection fraction (HFrEF) in Qatar has not been well characterized in the outpatient setting.

Objective: To describe the characteristics of patients with HFrEF who had improvement in their left ventricular ejection fraction (LVEF) and independent predictors of improvement.

Methods: This retrospective cohort study conducted at the advanced heart failure (HF) clinic in Qatar recruited patients who visited the clinic between January 2017 and December 2018.

Clinical, Radiological, and Outcome Characteristics of Acute Pulmonary Embolism: A 5-year Experience from an Academic Tertiary Center.

Background: Acute pulmonary embolism (PE) is a common and potentially life-threatening condition. This comprehensive study from a Gulf Cooperation Council (GCC) country aimed to evaluate the clinical, radiological, and outcome characteristics associated with acute PE.

Methods: This retrospective observational study analyzed data of patients with confirmed acute PE who were admitted to the largest academic tertiary center in the State of Qatar from January 1, 2014, to December 31, 2018.

Saddle versus non-saddle pulmonary embolism: differences in the clinical, echocardiographic, and outcome characteristics.

The central location, the size, and instability of saddle pulmonary embolism (PE) have raised considerable concerns regarding its hemodynamic consequences and the optimal management approach. Sparse and conflicting reports have addressed these concerns in the past. We aimed to evaluate the clinical presentation, hemodynamic and echocardiographic effects, as well as the outcomes of saddle PE, and compare the results with those of non-saddle type.
