Reduced-Dose Thrombolysis in Acute Pulmonary Embolism A Systematic Review

Addressing the rising trend of high-risk pulmonary embolism mortality: Clinical and research priorities

BACKGROUND

Deaths from high-risk pulmonary embolism (PE) appear to have increased in the US over the last decade. Modifiable risks contributing to this worrisome trend present opportunities for physicians, researchers, and healthcare policymakers to improve care.

METHODS

We sought to contextualize contemporary, high-risk PE epidemiology and examine clinical trials, quality improvement opportunities, and healthcare policy initiatives directed at reducing mortality.

RESULTS

We observed significant and modifiable excess mortality due to high-risk PE. We identified several opportunities to improve care including: (1) rapid translation of forthcoming data on reperfusion strategies into clinical practice; (2) improved risk stratification tools; (3) quality improvement initiatives to address presumptive anticoagulation practice gaps; and (3) adoption of health policy initiatives to establish pulmonary embolism response teams and address the social determinants of health.

CONCLUSION

Addressing knowledge and practice gaps in intermediate and high-risk PE management must be prioritized and informed by forthcoming high-quality data. Implementation efforts are needed to improve acute PE management and resolve treatment disparities.

Novel Risk Stratification and Hemodynamic Profiling in Acute Pulmonary Embolism: A Proposed Classification Inspired by Society for Cardiovascular Angiography and Intervention Shock Staging

Treatment options for patients with acute pulmonary embolism (PE) and right ventricular shock (RVS) have grown exponentially. Therapy options include anticoagulation, systemic thrombolysis, catheter-based thrombolysis/ thrombectomy, and may include short-term mechanical circulatory support. However, the incidence of short-term morbidity and mortality has not changed despite the emergence of several advanced therapies in acute PE. This is possibly due to the inclusion of heterogenous populations in research studies without differentiation based on the acuity/severity of presentation. We propose a novel classification for PE-RVS to allow for standardizing appropriate therapy escalation and better communication of the severity among cardiovascular critical care, and emergency health care professionals.
