Heart disease is often caused by a combination of factors, including high blood pressure, high cholesterol, smoking, diabetes, obesity, lack of physical activity, and an unhealthy diet. These factors can lead to the buildup of plaque in the arteries, which can restrict blood flow and increase the risk of heart attack or stroke. Other factors like age, family history, and stress can also contribute to heart disease. According to a study by the American Heart Association [https://www.ahajournals.org/doi/10.1161/CIR.0000000000000757], addressing modifiable risk factors can significantly reduce the risk of developing heart disease.
