NPPB and atrial fibrillation: The H2FPEF score is easier to understand and is based on six clinical factors: BMI > 30, ≥2 antihypertensive meds, AF, pulmonary artery systolic pressure >35 mmHg, age > 60, and E/e’ >9. NT-proBNP is not directly included in the score; however, the combination of H2FPEF and NT-proBNP enhances discrimination [2].
