What are the causes of coronary heart disease?

Several: Many things contribute; some modifiable, others not. Things you can't change include family history, gender, genetics (although you can test for the latter). Things you can change or at least affect: smoking (stop!), exercise, diet, cholesterol & other biomarkers, diabetes/prediabetes/insulin resistance, blood pressure. Remember that often the 1st sign of chd is sudden death-so don't wait!

Cholesterol: Cholesterol builds up in the wall of the arteries resulting in progressive narrowing. This process is accelerated by smoking, diabetes, high cholesterol, high blood pressure, inflammation (high c-reactive protein), and oxidative damage through aging.

Atherosclerosis: Depends on one's personal risks smoking, obesity, hypertension, hyperlipemia, diabetes , family history. Simply, one blocks the feeding coronary artery to part of the heart muscle and low flow, or no flow causes ischemia which cause death of the heart cells, which is a heart attack! myocardial infarction is the medical term.Ekg and lab tests show the damage.
