Symptoms of Coronary Heart Disease are listed as follows:
1. Arrhythmia
If your heart muscle is damaged or dies, this may make your heart beat abnormally (an arrhythmia). This may develop gradually as coronary heart disease progresses. You may feel an arrhythmia as a palpitation (a feeling of a skipping or thumping heart beat) or you may not notice it at all. The most serious arrhythmias may cause your heart to stop beating altogether (cardiac arrest). This is fatal unless you’re given immediate emergency first aid.

2. Heart attack
Sometimes a blood clot forms on top of the plaque in your coronary artery, blocking the artery completely. This may stop blood and oxygen from reaching part of your heart muscle, which can lead to a heart attack. It’s possible to have a heart attack without ever having had angina or any other symptoms. Symptoms of a heart attack may include the following.
--A feeling of heaviness, squeezing or crushing in the centre of your chest.
--Pain that may spread to your arms, neck, jaw, face, back or stomach.
--Feeling dizzy.
--Feeling breathless.
--Sweating.
--Feeling sick or vomiting.

3. Angina
Angina usually happens if the blood flow in the arteries that supply your heart is restricted. Angina typically starts when you're exerting yourself physically or feeling upset. It can also be brought on by cold weather or after a meal. Symptoms may include the following.
--Discomfort or tightness across your upper chest.
--Pain that spreads to your neck, jaw, throat, back or arms.
--Feeling out of breath or as if you’re choking.
--Angina usually lasts for a few minutes and disappears quickly when you rest.  

4. Heart failure
Coronary heart disease may weaken your heart and lead to heart failure. Heart failure means your heart isn't strong enough to pump blood around your body effectively and you get tired and out of breath easily. It can also cause swelling in your ankles and legs.
