Bova Score for Pulmonary Embolism Complications

Description

Calculates the Bova Score to stratify the risk of PE-related complications (death, hemodynamic collapse, or recurrent PE) within 30 days in normotensive patients with acute pulmonary embolism. This tool helps identify patients who, despite being hemodynamically stable at presentation, are at intermediate-to-high risk for deterioration.

Usage

bova_pe_score(sbp, heart_rate, troponin_elevated, rv_dysfunction)

Arguments

sbp	Numeric. Systolic Blood Pressure in mmHg. (90-100 mmHg adds +2 points).
heart_rate	Numeric. Heart rate in beats per minute. (>= 110 bpm adds +1 point).
troponin_elevated	Numeric (0 or 1). Cardiac troponin elevated above the institutional upper limit of normal. (1 = Yes, +2 points).
rv_dysfunction	Numeric (0 or 1). Right Ventricular dysfunction visible on echocardiogram or CT. (1 = Yes, +2 points).

Value

A list containing:

Bova_Score	The calculated score (Range 0-7).
Risk_Stage	Risk classification (Stage I: 0-2, Stage II: 3-4, Stage III: >4).
PE_Related_Complication_Risk_30Day	Estimated percentage risk of complications within 30 days.

Examples

# Example 1: High Risk (Stage III)
# SBP 95 (+2), HR 115 (+1), Troponin Neg (0), RV Dysfx (+2)
# Score = 5

# Example 2: Low Risk (Stage I)
# SBP 120 (0), HR 90 (0), Troponin Pos (+2), RV Normal (0)
# Score = 2
