Arteries are responsible for carrying oxygenated blood away from heart. There are different types of arteries like pulmonary arteries, systematic arteries and aorta. Coronary arteries are the first very first that branches off from the aorta, and they are responsible for supplying oxygenated and nutrient filled blood to the ventricle, septum of the heart and the heart muscle itself.

  • 1. Author: Lisa Brun Facts about Arterial Narrowing and Coronary Artery DiseaseArteries are responsible for carrying oxygenated blood away from heart. There aredifferent types of arteries like pulmonary arteries, systematic arteries and aorta.Coronary arteries are the first very first that branches off from the aorta, and they areresponsible for supplying oxygenated and nutrient filled blood to the ventricle, septum ofthe heart and the heart muscle itself. So they play a very important role in maintainingthe overall health of the heart.The food we take plays a vital role in keeping the coronary arteries clean and unclogged.Fat and cholesterol tend to accumulate inside the arterial wall over time and the buildupof cholesterol and fat starts from childhood. Eating healthy low fat food right fromchildhood helps to keep heart diseases at bay.Coronary artery(In French artères coronaires) disease otherwise called as arterialnarrowing or atherosclerosis is a condition where plaque builds up inside the coronaryarteries. The plaque made of cholesterol, fat and calcium builds inside the walls of thearteries there by reducing the diameter of the artery and restricts free flow of the blood.High fat in blood also tends to cause blood clots which also block the blood flow in thearteries. As the plaque grows over days, it hardens and causes angina or heart attack.The first symptom of arterial narrowing(In French le rétrécissement artériel) is mildchest pain, which indicates that oxygen rich blood does not flow properly into the heartmuscles. As the plaque thickens and grows in size, the chest pain increases gradually.When coronary arteries harden, heart exerts more pressure by squeezing the heartmuscle to pump the blood. The pain may also occur in neck, back, shoulder and jaw.Sometimes the coronary arteries worsen over time and remain silent until it is diagnosedfor palpitation or sudden heart attack. Arterial narrowing can weaken the heart musclewhich in turn can lead to heart failure. Heart failure is a condition that occurs when theheart muscles completely loose the ability to pump enough blood.Some of the main causes for arterial hardening are unhealthy cholesterol level, highblood sugar, insulin resistance, and obesity. Diabetes patients are more prone tocoronary arterial diseases because of high blood sugar level which in turn produces fat.High level of protein and triglycerides are also known to increase the risk. Arterialnarrowing also leads to sleep apnea, which is condition where breathing becomes shallowwhile sleeping. If the condition is left untreated then it can trigger heart attack. Most ofthe time, immediate physical activity after chest pain should be avoided as it exerts morepressure on the heart muscles and would cause more pain.
