H2FPEF Score (Heart Failure with Preserved EF Probability) Calculator

H2FPEF Score: Explanation and Clinical Context The H2FPEF Score is a validated diagnostic scoring system designed to estimate the likelihood of heart failure with preserved ejection fraction (HFpEF) in patients presenting with unexplained dyspnea. It integrates six easily measurable clinical and echocardiographic variables: Heavy (BMI ≥30 kg/m²), Hypertensive (≥2 antihypertensive medications), Atrial fibrillation, Pu

HF-CRT Echo Resynchronization Index Calculator

HF-CRT Echo Resynchronization Index: Explanation and Clinical Context The HF-CRT Echo Resynchronization Index is a composite echocardiographic measure designed to quantify the mechanical dyssynchrony and remodeling response in patients undergoing cardiac resynchronization therapy (CRT). It integrates key mechanical and electrical parameters that have been shown to predict CRT benefit, including septal-to-lateral dela
