Your Estimated Risk

This calculator provides an estimate based on common risk factors. It is not a diagnostic tool and should not replace consultation with a healthcare professional.
Understanding Heart Attack Risk Factors
Cardiovascular diseases, including heart attacks (myocardial infarction), remain a leading cause of mortality worldwide. While some risk factors are non-modifiable (like age and family history), many are lifestyle-related and can be managed. This calculator aims to provide a simplified estimation of your potential risk based on several key indicators.
Key Risk Factors Considered:
Age: The risk of heart attack generally increases with age, as arteries can become narrower and harder over time.
Gender: Historically, men have had a higher risk at younger ages, but women's risk increases significantly after menopause.
Blood Pressure (Systolic & Diastolic): High blood pressure (hypertension) forces the heart to work harder and can damage arteries, increasing the risk of heart attack and stroke.
Total Cholesterol: High levels of total cholesterol, particularly LDL ("bad") cholesterol, can contribute to plaque buildup in arteries (atherosclerosis).
HDL Cholesterol: High-density lipoprotein (HDL) cholesterol, often called "good" cholesterol, helps remove LDL cholesterol from arteries. Lower levels of HDL are associated with increased risk.
Smoking Status: Smoking damages blood vessels, increases blood pressure, reduces the amount of oxygen in the blood, and makes blood more likely to clot.
Diabetes: Diabetes significantly increases the risk of heart disease, as high blood sugar levels can damage blood vessels and nerves that control the heart.
Family History: A history of early heart disease in close relatives (parents, siblings) before age 60 suggests a potential genetic predisposition.
How the Calculator Works (Simplified Model)
This calculator uses a simplified scoring system inspired by established cardiovascular risk assessment models like the Framingham Risk Score. Each input is assigned a point value based on its contribution to heart attack risk, often weighted by age and gender. The total score is then translated into a qualitative risk level (e.g., Low, Moderate, High).
Important Note: Real-world risk calculators often employ complex statistical models and algorithms that consider interactions between variables and may have different scoring thresholds. This tool is for educational purposes and general awareness only.
Interpreting Your Results:
Low Risk: Indicates a relatively low chance of experiencing a heart attack within a defined timeframe (often 10 years), assuming current lifestyle and health status.
Moderate Risk: Suggests a noticeable risk that warrants attention and potential lifestyle modifications or medical consultation.
High Risk: Indicates a significant likelihood of experiencing a heart attack, strongly advising immediate consultation with a healthcare provider to discuss preventative strategies.
