Obstructive HCM Gradient Calculator

Calculates the resting and provoked LVOT gradient in hypertrophic obstructive cardiomyopathy (HOCM) using Doppler measurements. Helps determine treatment eligibility for septal reduction therapy.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates the resting and provoked LVOT gradient in hypertrophic obstructive cardiomyopathy (HOCM) using Doppler measurements. Helps determine treatment eligibility for septal reduction therapy

Each component has a specific meaning:

  • Doppler measurements — The doppler measurements recorded for the scenario being assessed.

Note: Interpret the hcm gradient result against the thresholds and context described above.
