Coronary artery disease (CAD) is a condition where plaque builds up inside the coronary arteries which supplies the heart with oxygen-rich blood.
Plaque narrows the arteries and reduces blood flow to the heart. It also makes it more likely that blood clots will form in the arteries.
Plaque is made up of fat, cholesterol, calcium and other substances found in the blood. When plaque builds up in the arteries, the condition is called CAD.
Over time, CAD can weaken the heart and lead to heart failure and arrhythmia. Heart failure is a condition in which the heart cannot pump enough blood throughout the body. Arrhythmia is related to irregularity of the speed or rhythm of the heartbeat.
Coronary artery disease (CAD) is caused by certain factors such as:
High amounts of certain fats and cholesterol in the blood
High blood pressure
High amounts of sugar in the blood due to insulin resistance or diabetes
