The Heart Health Index Calculator provides an overall measure of cardiovascular well-being by evaluating key health indicators such as resting heart rate, blood pressure, cholesterol levels, and physical activity. It calculates a heart health score on a scale from 0 to 100, where a higher value reflects a stronger and healthier cardiovascular system. This tool helps users understand how lifestyle and biological factors contribute to their heart condition, encouraging preventive habits such as balanced nutrition, regular exercise, and stress control. While it gives a helpful estimate, only medical professionals can provide an accurate assessment of heart health and related risks.
