American Heart Association Cardiovascular Health Score Calculator
This calculator helps estimate your cardiovascular health score based on key lifestyle factors. It is a simplified model and should not replace professional medical advice.
Your Cardiovascular Health Score will appear here.
Understanding Your Cardiovascular Health Score
The American Heart Association (AHA) emphasizes the importance of monitoring and improving cardiovascular health. This calculator provides a simplified estimation of your health score based on several key metrics that significantly influence heart disease risk. A higher score generally indicates better cardiovascular health and a lower risk of heart-related problems.
Factors Included and Their Significance:
- Age: Cardiovascular risk increases with age.
- Sex: Biological sex can influence risk factors and disease prevalence.
- Blood Pressure (Systolic & Diastolic): High blood pressure (hypertension) is a major risk factor, straining the heart and blood vessels.
- Total Cholesterol: High levels of LDL ("bad") cholesterol can lead to plaque buildup in arteries.
- Smoking Status: Smoking damages blood vessels, reduces oxygen in the blood, and significantly increases heart disease risk.
- Diabetes Status: Diabetes, particularly type 2, drastically increases the risk of cardiovascular disease due to its impact on blood sugar and blood vessel health.
- Physical Activity: Regular exercise strengthens the heart, improves blood pressure, cholesterol levels, and weight management. The AHA recommends at least 150 minutes of moderate-intensity aerobic activity per week.
- Diet Quality: A balanced diet rich in fruits, vegetables, whole grains, and lean proteins, while low in saturated fats, sodium, and added sugars, is crucial for heart health.
How the Score is Calculated (Simplified Model):
This calculator uses a weighted scoring system. Each input is assigned points based on its contribution to cardiovascular health. Generally:
- Favorable factors (e.g., normal blood pressure, non-smoker, high physical activity, good diet) contribute positively to the score.
- Unfavorable factors (e.g., high blood pressure, current smoker, diabetes, sedentary lifestyle, poor diet) detract from the score.
- Specific thresholds are used for each factor, and some factors may have different scoring weights depending on age and sex.
Example Calculation:
Consider a 45-year-old male, non-smoker, no diabetes, with blood pressure 130/85 mmHg, total cholesterol 220 mg/dL, engaging in 100 minutes of physical activity per week, and a diet quality score of 3.
The calculator would assess each factor:
- Age: Moderate impact.
- Sex: Male factor considered.
- BP: Slightly elevated, minor score reduction.
- Cholesterol: Borderline high, minor score reduction.
- Smoking: Never smoked, positive contribution.
- Diabetes: No, positive contribution.
- Physical Activity: Below recommended, moderate score reduction.
- Diet Quality: Average, neutral or slight reduction.
The final score would be an aggregation of these assessments, providing a general indication of cardiovascular health risk.
Disclaimer: This tool is for educational purposes only. It does not provide medical advice. Consult with a qualified healthcare professional for personalized health assessments and recommendations. The AHA uses more complex algorithms and clinical guidelines for actual risk assessments.

// — Scoring Logic (Simplified Example) —
// This is a highly simplified model. Real AHA calculations are complex.
// Age impact (higher age = lower score)
if (age > 60) score -= 15;
else if (age > 50) score -= 10;
else if (age > 40) score -= 5;
// Sex impact (example: female might have slightly different baseline risk perception in some models)
// For simplicity, we'll assume similar impact here, but a real model would have nuanced differences.
// Blood Pressure impact
if (systolicBP > 140 || diastolicBP > 90) {
score -= 15; // Stage 2 Hypertension or worse
if ((systolicBP > 130 && systolicBP 80 && diastolicBP 120 || diastolicBP > 80) {
score -= 3; // Prehypertension range
}
// Cholesterol impact (mg/dL)
if (cholesterol > 240) {
score -= 15; // Very High
} else if (cholesterol > 200) {
score -= 7; // Borderline High
}
// Smoking impact
if (smoking === "current") {
score -= 25;
} else if (smoking === "former") {
score -= 10;
}
// Diabetes impact
if (diabetes === "yes") {
score -= 20;
}
// Physical Activity impact (Minutes per week)
if (physicalActivity < 75) { // Less than half recommended minimum
score -= 10;
} else if (physicalActivity < 150) { // Below recommended minimum
score -= 5;
}
// Diet Quality impact (Scale 1-5)
if (dietQuality < 3) {
score -= 8;
} else if (dietQuality === 3) {
score -= 3;
