There is some literature on using the Bova score to decide on thrombolytics/interventional therapy as well. </p>
<p>Scoring Criteria:</p>
<ol>
<li>Score 2: Systolic <a href="https://fpnotebook.com/CV/Exam/BldPrsr.htm">Blood Pressure</a> 90-100 mmHg</li>
<li>Score 2: Elevated cardiac <a href="https://fpnotebook.com/CV/Lab/Trpn.htm">Troponin</a>
</li>
<li>Score 2: Right Ventricular Dysfunction
<ol>
<li>Right Ventricle to Left Ventricle ratio >0.9</li>
<li>Systolic pulmonary artery pressure >30 mmHg</li>
<li>Right ventricular free wall hypokinesis</li>
<li>Right ventricular dilatation (e.g. D-Sign)</li>
</ol>
</li>
<li>Score 1: <a href="https://fpnotebook.com/CV/Exam/HrtRt.htm">Heart Rate</a> >=110 bmp</li>
</ol>
<p>Interpretation:</p>
<ol>
<li>Stage 1: Bova Score 0-2 (low risk)
<ol>
<li>Mortality at 30 days: 3.1%</li>
<li>PE Related Complications: 4.4%</li>
</ol>
</li>
<li>Stage 2: Bova Score 2-4 (intermediate risk)
<ol>
<li>Mortality at 30 days: 6.8%</li>
<li>PE Related Complications: 18%</li>
</ol>
</li>
<li>Stage 3: Bova Score >4 (high risk)
<ol>
<li>Mortality at 30 days: 10%</li>
<li>PE Related Complications: 42%</li>
</ol>
