Long-Term Outcomes of Patients With Pulmonary Embolism Managed With Endovascular Therapies Compared to Medical Therapy.

ABSTRACT:

Background

Guidelines on the management of acute pulmonary embolism (PE) recommend consideration of endovascular therapies (EVT) for patients at intermediate-high risk. However, long-term data on the outcomes of patients after EVT as compared to medical therapy is lacking. This study aimed to compare outcomes of patients receiving EVT as compared to medical therapy alone at 3 to 6 months.

Methods

In this single-center, retrospective cohort study, 190 patients with PE underwent evaluation for presence of right ventricular (RV) dysfunction by transthoracic echocardiogram, residual perfusion defects on ventilation-perfusion scanning, and functional capacity by 6-minute walk distance (6MWD) at 3 to 6 month follow-up.

Results

Fifty-eight (31%) patients received EVT for the management of their acute PE. At follow-up (median 120 [97-170] days), 71% of patients who received EVT had normalization of RV function compared with only 34% of patients who received medical therapy alone (P < .001). Patients who received EVT had a significantly greater increase in their estimated glomerular filtration rate (P = .001), decrease in N-terminal proB-type natriuretic peptide (P = .003), and decrease in hemoglobin values (P = .018). Patients with intermediate-high to high risk PE who received EVT had significantly greater distance achieved on their 6MWD as compared to those who received medical therapy alone (P = .025).

Conclusions

Patients with acute PE who received EVT plus medical therapy were more likely to achieve normalization of RV dysfunction at 3 to 6 month follow-up compared to patients who received medical therapy alone. These data suggest that EVT is an effective therapy option for acute PE in intermediate-high and high risk patients with potential durable long-term benefits.

Project description:BackgroundThe benefit of catheter-directed therapy (CDT) for submassive pulmonary embolism (sPE) has been the subject of debate. We sought to determine the short- and long-term mortality and outcomes of CDT compared with anticoagulation for patients with sPE.MethodsWe performed a single healthcare network, multihospital, retrospective cohort study of hospitalizations for sPE from 2012 to 2019. sPE was defined as the presence of right heart strain or elevated biomarkers (troponin I or B-type natriuretic peptide). Patients with massive PE and those who had undergone systemic thrombolysis were excluded. The sPE groups included therapeutic anticoagulation alone or anticoagulation plus CDT (ie, thrombolysis or suction thrombectomy). The primary outcome was mortality at 1, 3, and 5 years. The other measured outcomes included PE-related death, short term mortality (30 days and 3 and 6 months), 30-day treatment-related complications (eg, bleeding, transfusion, stroke), chronic thromboembolic pulmonary hypertension, and 6-minute walk test at 1 year. After 1:1 nearest-neighbor propensity score matching, Kaplan-Meier survival plots were generated, and the treatment groups were compared using log-rank testing. We used Cox multivariate analysis to evaluate the outcomes after clustering at the hospital level, generating matched hazard ratios (mHRs) with associated 95% confidence intervals (CIs).ResultsOf 6746 sPE hospitalizations, the patients who had received CDT were younger (age, 58.9 ± 15.5 years vs 61.5 ± 17.4 years; P = .004), were more frequently White (92.5% vs 85.7%; P < .001), and had presented with a higher mean heart rate (104.6 bpm vs 94.9 bpm; P < .001), lower median systolic blood pressure (129 mm Hg vs 135 mm Hg; P < .001), and a greater incidence of right heart strain (79.2% vs 20.3%; P < .001). A total of 470 patients were matched, with 235 in the CDT group and 235 in the anticoagulation-only group. CDT was associated with a lower risk of mortality compared with anticoagulation at 1 year (7.6% vs 9.8%; mHR, 0.77; 95% CI, 0.65-0.92; P = .004), 3 years (11.1% vs 16.6%; mHR, 0.64; 95% CI, 0.55-0.73; P < .001), and 5 years (14.5% vs 19.1%; mHR, 0.71; 95% CI, 0.66-0.77; P < .001). Anticoagulation alone resulted in a greater incidence of PE-related deaths at 1, 3, and 5 years. The mortality at 30 days and 3 months was similar; however, CDT had resulted in better survival at 6 months (mHR, 0.81; 95% CI, 0.68-0.97; P = .02). No differences were found between the two groups in the incidence of bleeding complications at 30 days, development of chronic thromboembolic pulmonary hypertension, or the mean walking distance at 1 year.ConclusionsCDT plus anticoagulation for sPE was associated with improved long-term survival compared with anticoagulation alone, with a lower incidence of PE-related death and a low complication rate. CDT should be considered for select patients with sPE given its survival benefit.

Project description:ObjectivesAcute pulmonary embolism can be a life-threatening condition with a high mortality. The treatment choice is a matter of debate. The early and late outcomes of patients treated with surgical pulmonary embolectomy for acute pulmonary embolism in a single center were analyzed.MethodsAll consecutive patients operated on for pulmonary embolism between January 2002 and March 2017 were reviewed. Patient demographics and pre- and postoperative clinical data were retrieved from our patient registry, and risk factors for in-hospital and long-term mortality were identified.ResultsIn total, 175 patients (mean age 59±3 years, 50% male) were operated on for acute pulmonary embolism. In-hospital mortality was 19% (34/175). No differences were found when comparing surgery utilizing a beating heart or cardioplegic arrest. Risk factors for in-hospital mortality were age >70 years [odds ratio (OR) 4.8, confidence interval (CI) 1.7-13.1, p=0.002], body surface area <2 m2 (OR 4.7, CI 1.6-13.7, p=0.004), preoperative resuscitation (OR 14.1, CI 4.9-40.8, p<0.001), and the absence of deep vein thrombosis (OR 9.6, CI 2.5-37.6, p<0.001). Follow-up was 100% complete with a 10-year survival rate of 66.4% in 141/175 patients surviving to discharge. Once discharged from hospital, none of the risk factors identified for in-hospital mortality were relevant for long-term survival except the absence of deep vein thrombosis (OR 3.2, CI 1.2-8.2, p=0.019). The presence of malignancy was a relevant risk factor for long-term mortality (OR 4.3, CI 1.8-10.3, p=0.001).ConclusionSurgical pulmonary embolectomy as a therapy for acute pulmonary embolism demonstrates excellent short- and long-term results in patients with an otherwise life-threatening disease, especially in younger patients with a body surface area >2 m2 and pulmonary embolism caused by deep vein thrombosis. Pulmonary embolectomy should therefore not be reserved as a treatment of last resort for clinically desperate circumstances.
