Key points
- 1
Coronary heart disease develops when the arteries supplying blood to the heart become narrowed by a build-up of fatty deposits (atherosclerosis), reducing blood flow to the heart muscle. This can cause angina, and if an artery becomes completely blocked, a heart attack.

01 · Know
What is Coronary Heart Disease (CHD)?
Coronary heart disease develops when the arteries supplying blood to the heart become narrowed by a build-up of fatty deposits (atherosclerosis), reducing blood flow to the heart muscle. This can cause angina, and if an artery becomes completely blocked, a heart attack.
CHD develops over many years, influenced by factors like smoking, high blood pressure, high cholesterol, diabetes, and lifestyle. With the right combination of medication and lifestyle changes, the progression of CHD can be slowed significantly, and risk of complications reduced.
02 · Understand
Clinical context
Risk factors are often modifiable
Many of the strongest risk factors for coronary heart disease — smoking, high blood pressure, high cholesterol, and inactivity — can be meaningfully improved, which is why lifestyle changes and medication together make such a significant difference.

When to Seek Non-Emergency Review
- 1You have risk factors for CHD, such as smoking, high blood pressure, or a family history, and want to discuss your own risk
- 2You've been diagnosed and have questions about your medication or lifestyle changes
- 3You experience new or changing symptoms, such as breathlessness on exertion
04 · Prevent & manage
Practical steps
Chest Pain That Doesn't Ease with Rest Is Always an Emergency
While stable angina typically eases with rest, any chest pain that persists, worsens, or feels different from usual should be treated as a possible heart attack and needs emergency care immediately.
- 1Take all prescribed medication consistently.This typically includes medication to manage cholesterol, blood pressure, and reduce clotting risk.
- 2Stop smoking.This is one of the most significant steps you can take to reduce CHD progression and risk.
- 3Manage blood pressure and cholesterol.Both medication and lifestyle changes play an important role here.
- 4Stay physically active as advised by your doctor.Regular activity supports heart health and helps manage several risk factors together.
- 5Attend cardiac rehabilitation if recommended.This offers structured support for improving heart health and confidence in daily activity.
