About This Dictionary: This comprehensive guide explains each variable used in our heart disease prediction model. Use this reference to better understand what each field means and how to provide accurate information.

Variable	Description	Type	Values / Range	Notes
Age	Age of the patient.	Numeric Discrete	`18 - 80` years	Current age in completed years
Gender	Biological sex of the patient.	Categorical Nominal	`Male`, `Female`	Biological gender classification
Blood Pressure	Systolic blood pressure reading.	Numeric Continuous	`~120 - 180` mmHg	Key indicator of hypertension. Normal: <120, Elevated: 120-129, High: ≥130
Cholesterol Level	Total serum cholesterol level.	Numeric Continuous	`~150 - 300` mg/dL	Desirable: <200, Borderline: 200-239, High: ≥240
Exercise Habits	Self-reported level of physical activity.	Categorical Ordinal	`Low`, `Medium`, `High`	Weekly frequency and intensity of physical exercise
Smoking	Current smoking status.	Binary	`Yes`, `No`	Current tobacco smoking habit
Family Heart Disease	Family history of heart disease.	Binary	`Yes`, `No`	Genetic predisposition indicator
Diabetes	Diagnosed diabetes status.	Binary	`Yes`, `No`	Type 1 or Type 2 diabetes diagnosis
BMI	Body Mass Index.	Numeric Continuous	`~18 - 40` kg/m²	Calculated from weight and height. Underweight: <18.5, Normal: 18.5-24.9, Overweight: 25-29.9, Obese: ≥30
High Blood Pressure	Diagnosis of hypertension.	Binary	`Yes`, `No`	May be correlated with the Blood Pressure reading. Diagnosed hypertension history
Low HDL Cholesterol	Indicator of low High-Density Lipoprotein ("good" cholesterol).	Binary	`Yes`, `No`	HDL <40 mg/dL (men) or <50 mg/dL (women)
High LDL Cholesterol	Indicator of high Low-Density Lipoprotein ("bad" cholesterol).	Binary	`Yes`, `No`	LDL ≥160 mg/dL indicates high risk
Alcohol Consumption	Self-reported level of alcohol intake.	Categorical Ordinal	`None`, `Low`, `Medium`, `High`	Weekly alcohol consumption frequency
Stress Level	Self-reported level of stress.	Categorical Ordinal	`Low`, `Medium`, `High`	Psychological stress assessment scale
Sleep Hours	Self-reported average hours of sleep per night.	Numeric Continuous	`~4 - 10` hours	Recommended: 7-9 hours for adults
Sugar Consumption	Self-reported level of dietary sugar intake.	Categorical Ordinal	`Low`, `Medium`, `High`	Daily added sugar consumption level
Triglyceride Level	Level of triglycerides in the blood.	Numeric Continuous	`~100 - 400` mg/dL	A type of fat (lipid) found in your blood. Normal: <150, Borderline: 150-199, High: ≥200
