How this service works
Khan 2019 PCP-HF 10-year incident heart-failure percent for age 30-79 from sex, caller-assigned white or black cohort, treated or untreated systolic BP and fasting glucose, total and HDL cholesterol, BMI, smoking, and QRS duration. Table 2 coefficients. Caller assigns cohort; magent does not assign race. Not PREVENT 2024, not 2013 PCE, not a diagnosis or treatment order. magent does not assay lipids, measure blood pressure, or interpret an ECG.
Output
Returns the 10-year incident heart failure risk as a percentage, computed from Khan 2019 Table 2 PCP-HF coefficients using the supplied sex- and cohort-specific model terms including log-transformed age, SBP, glucose, BMI, cholesterol, HDL, QRS, and binary smoking and treatment flags.
Example use cases
Primary care cardiovascular risk panel
“Run the Khan 2019 PCP-HF 10-year heart failure risk calculation for a 63-year-old female in the black cohort: systolic BP 155 mmHg treated with antihypertensives, fasting glucose 118 mg/dL with no diabetes medication, BMI 31.2, total cholesterol 195 mg/dL, HDL 50 mg/dL, current smoker, QRS duration 88 ms.”
Untreated hypertension risk assessment
“What is the 10-year incident heart failure percent for a 45-year-old male in the white cohort with untreated systolic BP of 162 mmHg, fasting glucose of 98 mg/dL and no diabetes medication, BMI 27.5, total cholesterol 220 mg/dL, HDL 38 mg/dL, non-smoker, and QRS of 102 ms?”
Diabetes and elevated QRS risk stratification
“Calculate the Khan 2019 PCP-HF heart failure risk for a 70-year-old female in the black cohort: systolic BP 138 mmHg untreated, fasting glucose 145 mg/dL on diabetes medication, BMI 33.8, total cholesterol 178 mg/dL, HDL 44 mg/dL, non-smoker, QRS duration 120 ms.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/pcp_hfWhen to prefer
Choose this endpoint when you need to implement the specific Khan 2019 PCP-HF Table 2 model for 10-year heart failure risk in a primary care context for adults aged 30-79, and you have all 12 required clinical inputs including QRS duration. Do not use for PREVENT 2024, PCE 2013, diagnosis, or treatment orders. Prefer this over generic cardiovascular calculators when HF-specific risk (not ASCVD) is the clinical question.
Side effects
- Age outside 30-79 range is rejected
- Cohort value other than 'white' or 'black' is rejected
- SBP outside 50-250 mmHg range causes validation error
- QRS outside 40-300 ms range causes validation error
- Missing any required query parameter returns an error
- BMI outside 10-80 kg/m2 range is rejected
- HDL or cholesterol outside valid bounds causes error
- Payment not provided or insufficient USDC results in 402 response
